VEHICLE AND METHOD FOR CONTROLLING THE SAME

[0001] This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2018-0093578, filed on Aug. 10, 2018, the disclosure of which is incorporated by reference in its entirety.

[0002] The present disclosure relates to a vehicle and a method for controlling the same, and more particularly to a technology that advances a control start time of an advanced driver assistance system (ADAS) of a vehicle by operating the advanced driver assistance system (ADAS) based on driver awareness, as well as to increase a reference level for releasing an operation of the ADAS.

[0003] A vehicle typically travels on roads or move in various directions according to rotation of at least one wheel mounted to a vehicle body. Such vehicles may include, for example, a three-wheeled or four-wheeled vehicle, a two-wheeled vehicle such as a motorcycle, a motorized bicycle, construction equipment, a bicycle, a train traveling on rails, and the like.

[0004] The number of users of vehicles as simple transportation devices is rapidly increasing and with the rapid development of vehicle technology, vehicle users are able to travel longer distances distance travel. However, within areas with high population density, road traffic situations may be deteriorated thus increasing traffic congestion.

[0005] Recently, to mitigate driver's difficulty as well as to increase driver convenience during vehicle driving, many developers are conducting intensive research into a vehicle provided with an advanced driver assistance system (ADAS), such that the ADAS-embedded vehicle may actively provide the driver with various types of information, for example, vehicle states, driver's states, peripheral environment information, etc.

[0006] A representative example of the ADAS embedded in the vehicle may include a Smart Cruise Control System (SCCS), a Lane Keeping Assist System (LKAS), a Lane Departure Warning System (LDWS), a Forward Collision Avoidance (FCA) system, an Autonomous Emergency Brake (AEB) system, etc. The ADAS may determine the degree of possibility of collision between a host vehicle provided with the ADAS and another peripheral vehicle (or an oncoming vehicle) while the host vehicle is being driven. When there is a high possibility of collision between the host vehicle and other vehicles, the ADAS may allow the host vehicle to perform emergency braking to avoid collision between the host vehicle and other vehicles. Thus, the host vehicle provided with the ADAS may travel on roads while being spaced apart from a preceding vehicle by a constant distance and may also be prevented from inadvertently departing from a current lane.

[0007] Further, the ADAS may have difficulty in rapidly coping with either sudden vehicle manipulation of the driver operating the ADAS-embedded vehicle or sudden change in vehicle traveling environments. In addition, it is necessary for the ADAS to recognize driver intention in a manner that starting or stopping of the ADAS may be executed according to the recognized driver intention. For this reason, there is a need for new technology for automatically operating the ADAS by recognizing driver intention, guaranteeing the safety of vehicle traveling, and preparing for unexpected careless driving situations by releasing the ADAS only in a specific situation.

[0008] Therefore, it is an aspect of the present disclosure to provide a technology for advancing a control start time of an advanced driver assistance system (ADAS) of a vehicle by operating the advanced driver assistance system (ADAS) when there is a high possibility of careless driving by a driver (e.g., driver awareness) operating the vehicle, and increasing a reference level for releasing an operation of the ADAS to reduce the possibility of danger caused by such careless driving situation of the driver. Additional aspects of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

[0009] In accordance with an aspect of the present disclosure, a vehicle may include an image capturing device configured to detect an object by capturing an image of the object located in a peripheral region of a vehicle, a detection sensor configured to acquire at least one position information of the object and speed information of the object, an input configured to receive a command for starting an operation of an ADAS of the vehicle, and a controller configured to receive the command for starting the operation of the ADAS of the vehicle, start operation of the ADAS when a traveling environment and traveling status of the vehicle satisfy a predefined condition, advance a warning start time based on the operation of the ADAS by a predetermined time after starting operation of the ADAS, and allow an operation release reference value for releasing the operation of the ADAS to be higher than a predetermined value.

[0010] The controller may be configured to determine the traveling environment of the vehicle based on at least one of information detected by the image capturing device and information acquired by the detection sensor. The traveling environment of the vehicle may include at least one of a width of a road on which the vehicle 1 travels, a curvature (C1) of the road on which the vehicle travels, a distance to an obstacle located in a forward direction of the traveling vehicle, and a time-to-collision (TTC) time between the vehicle and the object. The controller may also be configured to determine the traveling status of the vehicle based on at least one of a traveling speed of the vehicle and a steering angle of the vehicle.

[0011] When the width of the road on which the vehicle travels is less than a predetermined length, when a curvature of the traveling road of the vehicle is less than a predetermined curvature value, when the distance between the vehicle and the obstacle is less than a predetermined distance, and when a time-to-collision (TTC) time between the vehicle and the object is longer than a predetermined time, the controller may be configured to determine that the traveling environment of the vehicle has satisfied the predefined condition. When the traveling speed of the vehicle is less than a predetermined speed and when the steering angle of the vehicle is less than a predetermined angle, the controller may be configured to determine that the traveling status of the vehicle has satisfied the predefined condition.

[0012] Further, the controller may be configured to calculate a time-to-collision (TTC) time between the vehicle and the object according to at least one of the position information and the speed information of the object detected by the detection sensor. When the advanced driver assistance system (ADAS) starts operation, the controller may be configured to advance a collision warning start time determined based on the calculated time-to-collision (TTC) time by a predetermined time.

[0013] When the ADA) starts operation, the controller may allow the operation release reference time for releasing the advanced driver assistance system (ADAS) operation to be higher than the predetermined value by a predetermined magnitude. When a numerical value of a variable based on a change of the traveling status of the vehicle is greater than the increased operation release reference time, the controller may be configured to stop operation of the advanced driver assistance system (ADAS). The numerical value of the variable based on the change of the traveling status of the vehicle may include at least one of a numerical value indicating a traveling speed of the vehicle and a numerical value indicating a steering angle of the vehicle.

[0014] When the numerical value indicating the traveling speed of the vehicle is greater than the increased operation release reference value, the controller may be configured to stop operation of the advanced driver assistance system (ADAS). When the numerical value indicating the steering angle of the vehicle is greater than the increased operation release reference value, the controller may be configured to stop operation of the advanced driver assistance system (ADAS). After lapse of a predetermined period of time from beginning of the operation of the advanced driver assistance system (ADAS), the controller may be configured to stop the operation of the advanced driver assistance system (ADAS). When the advanced driver assistance system (ADAS) starts operation and a command for stopping operation of the advanced driver assistance system (ADAS) is then input to the controller, the controller may be configured to stop operation of the advanced driver assistance system (ADAS).

[0015] The vehicle may further include a speed sensor configured to detect a traveling speed of the vehicle, and a speed regulator configured to regulate the traveling speed of the vehicle.

[0017] The method may further include determining the traveling environment of the vehicle based on at least one of information detected through the object image capturing and the acquired information. The traveling environment of the vehicle may include at least one of a width of a road on which the vehicle 1 travels, a curvature (C1) of the road on which the vehicle travels, a distance to an obstacle located in a forward direction of the traveling vehicle, and a time-to-collision (TTC) time between the vehicle and the object. The method may further include determining the traveling status of the vehicle based on at least one of a traveling speed of the vehicle and a steering angle of the vehicle.

[0018] Additionally, the method may include, when the width of the road on which the vehicle travels is less than a predetermined length, when a curvature of the traveling road of the vehicle is less than a predetermined curvature value, when the distance between the vehicle and the obstacle is less than a predetermined distance, and when a time-to-collision (TTC) time between the vehicle and the object is longer than a predetermined time, determining that the traveling environment of the vehicle has satisfied the predefined condition. When the traveling speed of the vehicle is less than a predetermined speed and when the steering angle of the vehicle is less than a predetermined angle, the method may include determining that the traveling status of the vehicle has satisfied the predefined condition.

[0019] The method may further include calculating a time-to-collision (TTC) time between the vehicle and the object according to at least one of the position information and the speed information of the object. The advancing of the warning start time by the predetermined time may include, after the advanced driver assistance system (ADAS) starts operation, advancing a collision warning start time determined based on the calculated time-to-collision (TTC) time by the predetermined time.

[0020] Further, the method may include, when the advanced driver assistance system (ADAS) starts operation, allowing the operation release reference time for releasing the advanced driver assistance system (ADAS) operation to be higher than the predetermined value by a predetermined magnitude, and when a numerical value of a variable based on a change of the traveling status of the vehicle is greater than the increased operation release reference time, stopping operation of the advanced driver assistance system (ADAS).

[0021] The numerical value of the variable based on the change of the traveling status of the vehicle may include at least one of a numerical value indicating a traveling speed of the vehicle and a numerical value indicating a steering angle of the vehicle. The method may further include, when the numerical value indicating the traveling speed of the vehicle is greater than the increased operation release reference value, stopping operation of the advanced driver assistance system (ADAS), and when the numerical value indicating the steering angle of the vehicle is greater than the increased operation release reference value, stopping operation of the advanced driver assistance system (ADAS).

[0044] Referring to FIG. 1, the vehicle 1 may include a detection sensor module 200. The detection sensor 200 may be configured to detect the presence or absence of a target object located in a forward direction of the vehicle 1, and acquire at least one of position information and traveling speed information of the detected target object. The detection sensor 200 according to one exemplary embodiment of the present disclosure may be configured to acquire at least one of position information and speed information of the target object located in the vicinity of the vehicle 1 based on the current position of the vehicle 1. In other words, the detection sensor 200 may be configured to acquire, in real time, coordinate information changed with movement of the target object, and may be configured to detect a distance between the vehicle 1 and the target object.

[0045] As will be described later, the controller 100 (see FIG. 2) may be configured to calculate a relative distance between the vehicle 1 and the target object and a relative speed between the vehicle 1 and the target object, upon receiving the target object position information and the target object speed information from the detection sensor module 200. Then, the controller may be configured to calculate a Time-To-Collision (TTC) time between the vehicle 1 and the target object using the calculated relative distance and the calculated relative speed.

[0046] As shown in FIG. 1, the detection sensor 200 may include a first detection sensor 200a, a second detection sensor 200b, and a third detection sensor 200c installed on the vehicle 1 to detect the presence or absence of other vehicles.

In accordance with one exemplary embodiment, the detection sensors 200 (200a, 200b, 200c) may be installed at the front, left, and right sides of the vehicle 1, such that the detection sensors 200 (200a, 200b, 200c) may be configured to detect the presence or absence of an object located in the forward direction of the vehicle 1, the presence or absence of an object located in a direction (hereinafter referred to as a front left direction) interposed between the left direction and the forward direction of the vehicle 1, and the presence or absence of an object located in a direction (hereinafter referred to as a front right direction) interposed between the right direction and the forward direction of the vehicle 1.

[0047] The first detection sensor 200a may be disposed at a radiator grille 6 of the vehicle 1. For example, the first detection sensor 200a may be installed in the radiator grille 6, and there is no limitation as to installation position of the first detection sensor 200a capable of detecting the presence or absence of a peripheral vehicle located in the forward direction of the vehicle 1. For convenience of description and better understanding of the present disclosure, the exemplary embodiment of the present disclosure has exemplarily disclosed that the first detection sensor 200a is disposed at the front center of the vehicle 1.

[0049] In accordance with one exemplary embodiment, the rear-lateral detection sensors of the rear lateral detection sensor 201 may be installed at both the left side and the right side of the vehicle 1, such that the rear-lateral detection sensors may be configured to detect the presence or absence of an object located in a direction (hereinafter referred to as a rear-left-lateral direction) interposed between the left lateral direction and the backward direction of the vehicle 1, and may also be configured to detect the presence or absence of an object located in a direction (hereinafter referred to as a rear-right-lateral direction) interposed between the right lateral direction and the backward direction of the vehicle 1.

The detection sensors of the detection sensor 200 may be implemented using any one of the above-mentioned sensors or a combination thereof. If one vehicle 1 is provided with the plurality of detection sensors 200, the respective detection sensors 200 may be implemented using the same or different devices, or may also be implemented using various devices and combinations capable of being considered by a system designer.

[0051] A display 303 for use within the vehicle 1 (hereinafter referred to as a display) may be installed at an upper panel of a dashboard (not shown). The display 303 may be configured to display or output images thereon to provide the driver or passenger with various types of information using the displayed images. For example, the display 303 may audio-visually provide the driver or passengers with maps, weather, news, music, various moving images or still images, and various types of information (e.g., air-conditioner information, etc.) associated with states or operations of the vehicle 1. In addition, the display 303 may provide the driver or passengers with various warning messages based on different danger levels.

[0052] In particular, when the vehicle 1 changes a current lane to another lane during vehicle driving or when there is a high possibility of collision between the vehicle 1 and other vehicles, the display 303 may be configured to output different warning messages based on different danger levels to the driver or passengers. In addition, even when the vehicle 1 has to deviate from a current lane or has to travel on roads while maintaining a constant distance to a preceding vehicle, the display 303 may be configured to output a warning message to the driver.

[0053] In addition, as will be described later, when the ADAS of the vehicle 1 starts or stops operation, the display 303 may be configured to provide the driver with operation state information of the system. The display 303 may also be implemented as a general navigation device as necessary. The center fascia (not shown) may be installed at the center of the dashboard, and may include one or more input parts 318 (318a to 318c) for allowing a user to input various commands associated with the vehicle 1. The input parts 318a to 318c may be implemented using a physical button, a switch, a knob, a touchpad, a touchscreen, a stick-type manipulation device, a trackball, or the like. The driver may control various operations of the vehicle 1 using the input parts 318a to 318c.

[0054] As will be described later, the driver of the vehicle 1 may input a command for starting the ADAS of the vehicle 1 through any input part. In other words, when the driver anticipates a high possibility of driver's careless driving situation during traveling of the vehicle 1 and inputs a command for starting the ADAS using the input part to prevent occurrence of such careless driving situation, the controller 100 may be configured to determine whether the traveling environment or the traveling status of the vehicle 1 corresponds to or satisfies a predetermined condition, to thus start operation of the ADAS when the predetermined condition is satisfied.

[0055] The dashboard may be connected to a steering wheel and an instrument panel that are arranged to face the driver seat. The steering wheel may be rotatable in a predetermined direction according to the driver's manipulation, and front wheels or rear wheels of the vehicle 1 may rotate in the rotation direction of the steering wheel to steer the vehicle 1 in a driver-desired direction. The steering wheel may include a spoke connected to a rotation shaft, and a knob wheel connected to the spoke. The spoke may also include at least one input part for receiving various commands from a user such as the driver. The input part may be implemented using a physical button, a knob, a touchpad, a touchscreen, a stick-type manipulation device, a track ball, or the like.

The speed sensor 80 may be configured to sense or detect a traveling speed of the vehicle 1. The storage unit 90 may be configured to store data associated with control of the vehicle 1. The controller 100 may be configured to adjust a traveling speed of the vehicle 1 as well as to operate respective constituent elements of the vehicle 1. The notification unit 304 may provide the driver with various types of information associated with the operation and traveling of the vehicle 1.

[0058] The speed regulator 70 may be configured to adjust or regulate the speed of the vehicle 1 steered by the driver. The speed regulator 70 may include an accelerator driver 71 and a brake driver 72. The accelerator driver 71 may be configured to operate an accelerator (e.g., acceleration pedal) upon receiving a control signal from the controller 100, thereby accelerating the vehicle 1. The brake driver 72 may be configured to operate a brake (e.g., brake pedal) upon receiving a control signal from the controller 100, thereby decelerating the vehicle 1. In other words, the controller 100 may be configured to operate the brake driver 72 based on a time-to-collision (TTC) time of the vehicle 1, thereby adjusting the braking of the vehicle 1.

[0059] The controller 100 may be configured to accelerate or decelerate the vehicle 1 to either decrease or increase a distance between the vehicle 1 and another object based on the distance between the vehicle 1 and another object and also based on a predefined reference distance stored in the storage unit 90. In addition, the controller 100 may be configured to calculate a TTC time between the vehicle 1 and a target object based on a relative distance between the vehicle 1 and the target object and also based on a relative speed between the vehicle 1 and the target object, and may be configured to transmit a signal for adjusting the traveling speed of the vehicle 1 based on the calculated TTC time to the speed regulator 70.

[0060] The speed regulator 70 may be configured to adjust or regulate the traveling speed of the vehicle 1 under control of the controller 100. When there is a high possibility of collision between the vehicle 1 and another object, the speed regulator 70 may be configured to reduce the traveling speed of the vehicle 1 by decelerating the vehicle 1. The speed sensor 80 may be configured to detect the traveling speed of the vehicle 1 steered by the driver upon receiving a control signal from the controller 100. In other words, the speed sensor 80 may be configured to detect the traveling speed of the vehicle 1 using a rotation speed of wheels of the vehicle 1. The traveling speed of the vehicle 1 may be denoted by [kph] (where kph: kilometer per hour), expressing the number of kilometers travelled in one hour [h].

[0061] The storage unit 90 may be configured to store various types of data related to control of the vehicle 1. In particular, the storage unit 90 may be configured to store a traveling speed, a traveling distance, and a traveling time of the vehicle 1. The storage unit 90 may also be configured to store position information and speed information of a target object that is captured by the image capturing part 350 or detected by the detection sensor module 200, and store real-time coordinate information of a target object moving from place to place, a relative distance between the vehicle 1 and the target object, and a relative speed between the vehicle 1 and the target object. The storage unit 90 may be configured to store data of the TTC time that is calculated in real time by the controller 100 during traveling of the vehicle 1.

[0062] Further, the storage unit 90 may be configured to store predefined conditions associated with the traveling environment and traveling status of the vehicle 1. Particularly, the predefined conditions are needed to start operation of the ADAS of the vehicle 1. The storage unit 90 may also be configured to store data associated with a predetermined time needed for starting or releasing the ADAS. The storage unit 90 may be configured to store data regarding numerical equations and control algorithm needed to operate the vehicle 1 therein, and the controller 100 may be configured to output a control signal for operating the vehicle 1 according to the numerical equations and the control algorithm.

[0063] Although the storage unit 90 may be implemented as any one of a non-volatile memory (e.g., a cache, a Read Only Memory (ROM), a Programmable ROM (PROM), an Erasable Programmable ROM (EPROM), an Electrically Erasable Programmable ROM (EEPROM), a flash memory, etc.), a volatile memory (e.g., a Random Access Memory (RAM)), and a storage medium (e.g., a Hard Disk Drive (HDD), a CD-ROM, etc.), the scope or spirit of the present disclosure is not limited thereto. The storage unit 90 may be a memory that is implemented as a separate chip independent of the above processor related to the controller 100, or may be implemented as a processor and a single chip.

[0064] Referring back to FIG. 2, at least one controller 100 may be provided within the vehicle 1. The controller 100 may be configured to electronically operate constituent elements related to the operation of the vehicle 1. A vehicle and a method for controlling the same according to the exemplary embodiment of the present disclosure will hereinafter be described with reference to FIG. 3A and FIG. 3B.

[0065] The ADAS of the vehicle 1 may have difficulty in rapidly responding to either sudden vehicle manipulation of the driver or sudden change in vehicle traveling environments during traveling of the vehicle 1. In other words, if another vehicle suddenly cuts in front of the driver's vehicle 1 (i.e., a host or subject vehicle) while the driver is distracted and not maintaining a forward direction of eyesight, the ADAS of the host vehicle 1 may not rapidly respond to a high possibility of collision with another vehicle. Moreover, if an unexpected dangerous situation (e.g., driver's coughs or sneezes) occurs in the traveling time of the host vehicle 1, the driver may have difficulty in safely steering the host vehicle 1 due to such dangerous situation, and thus, the host vehicle 1 steered by the driver may suddenly deviate from a current lane.

[0066] Therefore, according to the vehicle and the method for controlling the same, if there is a higher possibility of such unexpected situations during traveling of the vehicle 1, the driver may input a desired control command to the input 318 to authorize the vehicle 1 to control vehicle traveling. If there is a high possibility that an unexpected situation associated with operation of the vehicle 1 will occur during driving of the vehicle 1, the driver may input a command for starting the ADAS of the vehicle 1 using the input 318. The input 318 designed to receive the above control command may be implemented as a button or switch, or may also be implemented in various shapes without departing from the scope or spirit of the present disclosure.

[0067] If a driver intention determination unit 130 contained in the controller 100 receives the command for starting the ADAS from the driver, this signals that the driver of the vehicle 1 is concern about the possibility of careless driving and thus inputs the command for starting the ADAS through the input. If the controller 100 receives the command for starting the ADAS from the driver (1000), the controller 100 may be configured to confirm traveling environments and traveling statuses of the vehicle 1 moving on the roads to determine whether to activate the ADAS of the vehicle 1. In other words, the command provided by the driver regarding driven intention may be input prior to any detection of careless driving such that the ADAS may take control of vehicle operation when such driving is detected. Careless driving may include detecting driver distraction, unintentional lane change (e.g., swerving), unintentional sudden engagement of accelerator pedal, or the like.

[0068] In other words, from the viewpoint of a current traveling environment and current traveling status of the vehicle 1, upon determining that the authority to control vehicle traveling is allocated to the driver without being allocated to the vehicle 1, the controller 100 may be configured to prevent activation of the ADAS even when the driver inputs the command for starting the ADAS of the vehicle 1. The controller 100 may be configured to determine the traveling environment of the vehicle 1 based on target object information detected by the image capturing part 350 and also the position and speed information of the target object detected by the detection sensor module 200.

[0069] Referring to FIG. 4, the traveling environment of the vehicle 1 may include at least one of a width (W1) of the road on which the vehicle 1 travels, a curvature (C1) of the road on which the vehicle 1 travels, a distance to an obstacle (ob) located in a forward direction of the moving vehicle 1, and a TTC time between the vehicle 1 and a target object. A traveling environment recognizer 110 contained in the controller 100 may be configured to recognize various traveling environments of the vehicle 1.

[0070] In particular, a target object located close to (e.g., in a predefined vicinity of the vehicle) the vehicle 1 (i.e., a host vehicle) may be another vehicle 2 that is moving in front of the host vehicle 1, or may be yet another vehicle 3 that is moving on crossroads or alleys located ahead of the current lane of the host vehicle 1. In other words, when the controller 100 determines the traveling environment of the vehicle 1 based on the above-mentioned factors, if it is undesirable that traveling of the vehicle 1 be adjusted using the ADAS of the vehicle 1 or if the operation for adjusting traveling of the vehicle 1 using the ADAS is considered unsafe, the controller 100 may be configured to prevent activation of the ADAS.

[0071] As described above, various factors capable of allowing the controller 100 to determine the traveling environment of the vehicle 1 may include not only the above-mentioned factors but also other factors. The controller 100 may be configured to determine whether the traveling environment of the vehicle 1 corresponds to or satisfies a predefined condition (1100). In particular, if the width (W) of the road on which the vehicle 1 travels is less than a predetermined length, the controller 100 may be configured to determine that the traveling environment of the vehicle 1 has satisfied the predefined condition. In addition, if the width (W) of the road on which the vehicle 1 travels is equal to or greater than the predetermined length, the controller 100 may be configured to determine a high possibility of collision between the vehicle 1 and another object, in which it may be undesirable to activate the ADAS without driver intention.

[0072] Further, if the curvature (C1) of the current lane of the vehicle 1 is less than a predetermined curvature value, the controller 100 may be configured to determine that the traveling environment of the vehicle 1 has satisfied the predefined condition. In particular, if the curvature (C1) of the current lane of the vehicle 1 is equal to or greater than the predetermined curvature value, the controller 100 may be configured to determine a high possibility of collision between the vehicle 1 and another object (e.g., peripheral vehicle 2 or 3 moving in front of the vehicle 1), in which it may be undesirable to activate the ADAS without driver intention.

[0073] Additionally, if the distance between the vehicle and the obstacle (ob) is less than a predetermined distance, the controller 100 may be configured to determine that the traveling environment of the vehicle 1 has satisfied the predefined condition. In particular, if the distance between the vehicle 1 and the obstacle (ob) is equal to or greater than the predetermined distance, the controller 100 may be configured to determine a high possibility of collision between the vehicle 1 and the obstacle (ob), in which it may be undesirable to activate the ADAS activation without driver intention.

[0074] In addition, if a TTC time between the vehicle 1 and a target object is greater than a predetermined time, the controller 100 may be configured to determine that the traveling environment of the vehicle 1 has satisfied the predefined condition. In particular, if the TTC time between the vehicle 1 and the object is equal to or less than the predetermined time, the controller 100 may be configured to determine a high possibility of collision between the vehicle 1 and the object, in which it may be undesirable to activate the ADAS without driver intention. Particularly, the target object located close to the vehicle 1 may be a peripheral vehicle 2 that is moving in front of the vehicle 1, or may be another peripheral vehicle 3 that is moving on crossroads or alleys located ahead of the current lane of the vehicle 1.

[0075] As shown in FIG. 4, the controller 100 may consider the traveling environments of the vehicle 1, for example, the width (W) and the curvature (C1) of the current lane of the vehicle 1, and may be configured to determine whether the distance between the vehicle 1 and either the obstacle (ob) or another object may be sufficiently guaranteed (i.e., determine whether the vehicle 1 is moving within a specific region Si in which current driving safety is guaranteed). In other words, if the traveling environment of the vehicle 1 corresponds to or satisfies the predefined condition, the controller 100 may be configured to determine to start operation of the ADAS.

[0076] The controller 100 may be configured to determine the traveling status of the vehicle 1 based on at least one of the traveling speed of the vehicle 1 and the steering angle of the vehicle 1. A traveling status recognizer 120 contained in the controller 100 may be configured to recognize various traveling statuses of the vehicle 1. In other words, when the controller 100 determines the traveling environment of the vehicle 1 based on various factors of the vehicle 1 (e.g., the traveling speed and the steering angle of the vehicle 1), if it is undesirable or unsafe for ADAS activation to be execute to control traveling of the vehicle 1, the controller 100 may be configured to prevent activation of the ADAS.

[0077] As described above, various factors for allowing the controller 100 to determine the traveling statuses of the vehicle 1 may include the above-mentioned factors and also other factors. The controller 100 may be configured to determine whether the traveling status of the vehicle 1 corresponds to or satisfies the predetermined condition (1200). In particular, if the traveling speed of the vehicle 1 detected by the speed sensor 80 is less than a predetermined speed, the controller 100 may be configured to determine that the traveling status of the vehicle 1 has satisfied the predefined condition. If the traveling speed of the vehicle 1 is equal to or greater than the predetermined speed, the controller 100 may be configured to determine a high possibility of collision between the vehicle 1 and another object, in which it may be undesirable to activate the ADAS without driver intention.

[0078] In addition, if the steering angle detected by a steering sensor (not shown) of the vehicle 1 is less than a predetermined angle, the controller 100 may be configured to determine that the traveling status has satisfied the predefined condition. In particular, if the steering angle of the vehicle 1 is equal to or greater than the predetermined angle, the controller 100 may be configured to determine a high possibility of collision between the vehicle 1 and another object, and the steering angle of the vehicle 1 is changed according to driver intention, in which it may be undesirable to activate the ADAS without driver intention. In other words, if the traveling status of the vehicle 1 corresponds to or satisfies the predefined condition, the controller 100 may be configured to start operation of the ADAS.

[0079] As described above, if the controller 100 receives the command for starting the ADAS of the vehicle 1 and determines that the traveling environment and traveling status of the vehicle 1 have satisfied the predefined condition, the controller 100 may be configured to start the ADAS of the vehicle 1 (1300). The above-mentioned ADAS may include at least one of a Smart Cruise Control System (SCCS), a Lane Keeping Assist System (LKAS), a Lane Departure Warning System (LDWS), a Forward Collision Avoidance system, and an Autonomous Emergency Brake (AEB) system. If necessary, the above-mentioned ADAS may further include various types of ADAS-based auxiliary systems.

[0080] The controller 100 may be configured to activate only one of the above-mentioned various advanced driver assistance systems (ADASs) of the vehicle 1, or may be configured to activate a plurality of systems to be simultaneously or sequentially as necessary. If the ADAS of the vehicle 1 starts operation, the controller 100 may be configured to advance a warning start time based on the ADAS by a predetermined time (1400).

[0081] As described above, in association with the target object located close to the vehicle 1 (e.g., within a predetermined distance from the subject vehicle) traveling within the same lane, the controller 100 may be configured to calculate a TTC time between the vehicle 1 and the target object based on at least one of position information and speed information of the target object detected by the detection sensor module 200. If the ADAS starts operation, the controller 100 may be configured to advance a collision warning start time decided based on the TTC time by a predetermined time.

[0082] Referring to FIG. 5, if a target object located in front of the host vehicle 1 traveling in the same lane is determined to be the peripheral vehicle 2, the controller 100 may be configured to calculate a TTC time between the host vehicle 1 and the peripheral vehicle 2 based on the position and speed information of the peripheral vehicle 2 detected by the detection sensor 200 and also the traveling speed of the host vehicle 1. The controller 100 may be configured to transmit a signal warning of collision between the host vehicle 1 and the peripheral vehicle 2 based on the calculated TTC time, and the display 303 and the notification unit 304 may be configured to transmit a warning message to the driver based on the transmitted warning collision signal.

[0083] Referring to FIG. 5, before the ADAS of the host vehicle 1 starts operation, a collision warning start time for warning of the danger of collision between the host vehicle 1 and the peripheral vehicle 2 may be set to a specific time point (t2), and a TTC time between the host vehicle 1 and the peripheral vehicle 2 at the time point (t2) may be set to a time point (Tb). In other words, before the ADAS of the host vehicle 1 starts operation, the controller 100 may be configured to output the collision warning signal at the time point (t2) where the TTC time between the host vehicle 1 and the peripheral vehicle 2 has a time duration (Tb) left until the host vehicle 1 collides with the peripheral vehicle 2. In contrast, after the ADAS of the host vehicle 1 starts operation, the controller 100 may be configured to advance the collision warning start time by a predetermined time, to thus output the collision warning signal at a time point (t1) where the TTC time between the host vehicle 1 and the peripheral vehicle 2 has a time duration (Ta) left until the host vehicle 1 collides with the peripheral vehicle 2.

[0084] Meanwhile, a braking start time for braking the host vehicle 1 to prevent collision between the host vehicle 1 and the peripheral vehicle 2 may be set to a time point (t3) before the ADAS of the host vehicle 1 starts operation, and may also be set to the time point (t3) even after the ADAS of the host vehicle 1 starts operation. In other words, as shown in FIG. 5, assuming that the distance between the host vehicle 1 and the peripheral vehicle 2 colliding with each other is set to zero ‘0’, before the ADAS of the host vehicle 1 starts operation, the controller 100 may be configured to output the collision warning signal when the host vehicle 1 is located at a specific position (d2), and may be configured to execute braking of the host vehicle 1 when the host vehicle 1 is located at another position (d1).

[0085] In contrast, after the ADAS of the host vehicle 1 starts operation, the controller 100 may be configured to output the collision warning signal when the host vehicle 1 is located at a position (d3), to provide the driver of the host vehicle 1 with a sufficiently long reaction time prior to collision with the host vehicle 1. In addition, although the controller 100 may advance the collision warning start time between the host vehicle 1 and another object, if the host vehicle 1 deviates from a current lane, the controller 100 may be configured to advance a lane departure warning start time. The controller 100 may also be configured to advance a start time of any other warning messages as necessary.

[0086] In other words, if the driver of the host vehicle 1 anticipates occurrence of careless driving situation during traveling of the host vehicle 1, and inputs the command for starting the ADAS of the host vehicle 1, such that the ADAS of the host vehicle 1 starts operation, the controller 100 may be configured to advance a start time of various warning messages to be output to the driver of the host vehicle 1. Therefore, the controller 100 may guarantee safety in driving of the host vehicle 1 even when the driver's careless driving situation of the host vehicle 1 occurs.

[0087] Warning messages associated with traveling and operation of the host vehicle 1 may be visually output to the driver of the host vehicle 1 through the display 303. Alternatively, warning messages associated with traveling and operation of the host vehicle 1 may also be audibly output to the driver of the host vehicle 1 through the notification unit 304. When the ADAS starts operation, the controller 100 may be configured to adjust a reference value for releasing the ADAS operation to be higher than a predetermined value (1500). In other words, since the driver of the host vehicle 1 inputs a command for starting the ADAS after anticipating occurrence of a careless driving situation, and the ADAS is then activated by the command, the controller 100 may be configured to maintain the activation of the ADAS (e.g., prevent release thereof) even when the driver's careless driving situation occurs.

[0088] There are various examples of such careless driving situation of the driver operating the host vehicle 1. For example, during traveling of the host vehicle 1, when the driver sneezes or coughs, or when the driver fails to keep eyes forward or is otherwise distracted, the driver belatedly realizes the approaching danger and thus unintentionally turns the steering wheel to the right or left. In another example, since the driver neglects looking forward while driving the host vehicle 1, the driver may mistake an accelerator for a brake, resulting in traffic accidents.

[0089] A conventional ADAS-embedded vehicle has been designed to automatically release the ADAS operation when a driver of the vehicle repeatedly intervenes in vehicle control at least a predetermined number of times during the ADAS operation. As a result, although the conventional ADAS-embedded vehicle starts operation of the ADAS after anticipating occurrence of a careless driving situation, when the careless driving situation occurs, the ADAS operation is unavoidably released.

[0090] In contrast, according to the exemplary embodiment of the present disclosure, when the ADAS of the vehicle 1 starts operation, the controller 100 may be configured to continuous monitor the vehicle surroundings and detect driver intention during a predetermined time (t_m). In other words, if a numerical value of a predetermined variable is changed according to a change of the traveling status of the vehicle 1, the driver intention determination unit 130 contained in the controller 100 may be configured to determine whether the driver directly attempts to operate the vehicle 1 to change the traveling status of the vehicle 1.

[0091] As illustrated in the graph of FIG. 6, if a numerical value affected by the traveling status changed at a specific time point (t_b) is increased up to a predetermined value or higher during traveling of the vehicle 1, the controller 100 may be configured to determine the presence or absence of the driver's control intention. In particular, the numerical value of the variable based on the changed traveling status of the vehicle 1 may include at least one of a numerical value that indicates the traveling speed of the vehicle 1 and a numerical value that indicates the steering angle of the vehicle 1.

[0092] In other words, the controller 100 may be configured to determine the degree of the instantaneous change of the traveling speed of the vehicle 1 or may be configured to determine whether the steering angle of the vehicle 1 is changed by a predetermined angle or greater. As a result, in response to receiving the above determination results, the controller 100 may be configured to determine whether the driver intends to directly adjust driving of the vehicle 1 although the ADAS operation is being executed.

[0093] As illustrated in FIG. 6, the controller 100 may be configured to adjust the reference value for releasing the ADAS operation to be greater than a predetermined reference value by a predetermined magnitude. In other words, before the ADAS of the vehicle 1 starts operation, the reference value for releasing the ADAS operation may be set to ‘V1’. In contrast, after the ADAS of the vehicle 1 starts operation, the reference value for releasing the ADAS operation may increase up to ‘V2’.

[0094] During operation of the vehicle 1, the controller 100 may be configured to determine the numerical value of the variable based on the traveling status change of the vehicle 1 that is monitored during a predetermined time (t_m). In particular, if the determined numerical value of the variable is greater than the increased reference value (V2) for releasing the ADAS operation, the controller 100 may be configured to stop operation of the ADAS (1900). The controller 100 may then be configured to determine whether the numerical value of the variable based on the changed traveling status of the vehicle 1 is greater than the operation release reference value increased by initiation of the ADAS (1600).

[0095] In other words, although the operation release reference value increases from V1 to V2 due to such initiation of the ADAS, if the numerical value of the variable based on the traveling status change of the vehicle 1 is greater than the increased operation release reference value, the driver intends to intervene in control of the vehicle 1, and thus, the controller 100 may be configured to stop operation of the ADAS of the vehicle 1.

[0096] Meanwhile, if the numerical value of the variable based on the traveling status change of the vehicle 1 is less than the increased operation release reference value, the controller 100 may be configured to continue the operation of the ADAS of the vehicle 1 (e.g., not stop operation thereof), to allow the ADAS to be continuously controlled to properly respond to either the increasing traveling speed of the vehicle 1 affected by the driver's careless driving situation or the instantaneous change of the steering angle.

[0097] Referring to FIG. 6, assuming that a Lane Keeping Assist System (LKAS) or a Lane Departure Warning System (LDWS) operates as the ADAS of the vehicle 1, if the numerical value of the variable based on the traveling status change of the vehicle 1 is greater than the operation release reference value (V1) under the condition that the operation release reference value of the system is not increased (V1), the ADAS operation may be released, and thus, the vehicle 1 deviates from the lane and moves to a position (1a). In other words, since the system operation is released even when the vehicle 1 is operated by instantaneous careless driving of the driver at the operation state (V1) in which the operation release reference value of the ADAS is not increased, the Lane Keeping Assist System (LKAS) or the Lane Departure Warning System (LDWS) may not operate.

[0098] On the other hand, in the operation status (V2) in which the operation release reference value of the ADAS is increased, the numerical value of the variable based on the traveling status change of the vehicle 1 less than the operation release reference value (V2), the ADAS operation may not be released. As a result, even when the vehicle 1 attempts to deviate from the lane due to occurrence of the driver's instantaneous careless driving, the vehicle 1 may be located at the position (1b) without deviating from the lane through the LKAS or LDWS operation.

[0099] If the numerical value indicating the traveling speed of the vehicle 1 is greater than the increased operation release reference value, the controller 100 may be configured to stop operation of the ADAS. If the numerical value indicating the steering angle of the vehicle 1 is greater than the increased operation release reference value, the controller 100 may be configured to stop operation of the ADAS (1900). In addition, the controller 100 may be configured to determine whether a predetermined period of time has elapsed after activation of the ADAS of the vehicle 1 (1700). If the predetermined time has elapsed, the controller 100 may be configured to stop operation of the ADAS (1900).

[0100] If the driver inputs the command for stopping the ADAS through the input 318 during activation of the ADAS, the controller 100 may be configured to determine whether the command for stopping the ADAS has been received (1800), and may thus stop operation of the ADAS. Various types of information associated with the above-mentioned control and operations of the vehicle 1 may be supplied to the driver through the display 303.

[0101] The vehicle and the method for controlling the same according to the exemplary embodiment of the present disclosure have the following effects. The vehicle may automatically operate the ADAS by recognizing driver intention, such that the vehicle may advance a control start time of the ADAS, resulting in driving safety of the vehicle. In addition, the vehicle may raise the operation release reference level of the ADAS, such that the ADAS is released only in a specific situation, and a dangerous driving situation caused by occurrence of an unexpected careless driving situation may be prevented.

[0102] The above-mentioned embodiments may be implemented in the form of a recording medium storing commands capable of being executed by a computer system. The commands may be stored in the form of program code. When the commands are executed by the processor, a program module is generated by the commands so that the operations of the disclosed exemplary embodiments may be carried out. The recording medium may be implemented as a non-transitory computer-readable recording medium. The non-transitory computer-readable recording medium includes all types of recording media storing data readable by a computer system. Examples of the non-transitory computer-readable recording medium include a Read Only Memory (ROM), a Random Access Memory (RAM), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, etc.

[0103] As is apparent from the above description, the vehicle and the method for controlling the same according to the exemplary embodiments of the present disclosure may advance a control start time of the ADAS by automatically operating the advanced driver assistance system (ADAS) after recognizing driver intention, resulting in guarantee of safe driving. In addition, the vehicle may release operation of the ADAS only in a specific situation by raising a reference level for releasing the operation of the ADAS, such that the possibility of danger caused by unexpected careless driving is greatly reduced.

[0104] Although a few exemplary embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
