Abstract
A system and method to identify fuel consumption optimization based on reactive and deliberative components is described. Modifiable use conditions, such as speeding, excessive idling, gear selection, acceleration and deceleration profiles, which all represent opportunities for fuel savings, are identified and optimized for minimal fuel consumption based on a reactive interaction with the vehicle on a real-time basis. Deliberative analysis of historical data linked to a specific location or route is also conducted to arrive at a historical optimal fuel consumption profile. Similar historical fuel consumption profiles for the same route in question from other nearby vehicles are collected and analyzed to determined a more robust deliberative component of optimal fuel consumption. The reactive and deliberative components are optimized fuel consumption are merged to form a recommended profile for optimal fuel consumption.

Background of the Invention
[0002] 1. Field of the Invention
[0003] Embodiments of the present invention relate, in general, to vehicular management systems, and more particularly, to systems and related methodology for improved fuel efficiency based on reactive and historical data analysis.
[0004] 2. Relevant Background
[0005] Modern vehicles are typically equipped with one or more computer systems. These systems often provide, among other things, information relating to the vehicle's fuel economy. There are many different versions of these types of devices but generally, each of them provide information with respect to the vehicle's current or historical fuel efficiency. For example, one display may provide and “instantaneous” miles per gallon while another may provide “average” miles per gallon over a specified trip or time frame. Most models of vehicles on the road today can provide this type of information to users with reasonable accuracy. Little information, however, is provided to give the user an indication of what steps can be taken to improve fuel efficiency.
[0006] Similarly, navigation systems that are either integrated into a vehicle or added as after market products are widely available that can provide detailed directions regarding a quickest route to a destination or a route that avoids toll roads, ferries or even traffic delays. However, current systems however do not offer a user with route guidance as to how to modify their route to increase fuel efficiency. Moreover, little or no information is provided as how to modify the control of a vehicle to optimize fuel efficiency. For example, it is widely accepted that vehicles consume less fuel at slower speeds.
[0007] One basis for that assumption is that as vehicle speed increases, the resistance induced from moving through the air (drag) increases just as is experienced with an aircraft. Such a statement is substantially true in controlled conditions, however, real world driving does not occur in a controlled environment. In reality, better fuel efficiency may be achieved by maintaining a higher speed on one segment of a road and a lower speed on another segment due to several competing factors. For example, if we assume at least one factor for determining fuel efficiency is drag experienced by the vehicle due to wind resistance, then to increase fuel efficiency when traveling with a tail wind, one should speed up. These and other considerations and deficiencies of the prior art are addressed by one or more embodiment of the present invention.
Summary of the Invention
[0008] A system for managing the consumption of fuel can, according to one embodiment of the present invention, include a reactive module and a deliberative module. The reactive module is operable to determine a real-time vehicle speed for optimal fuel efficiency while the deliberative module can determine a vehicle speed for optimal fuel efficiency for a particular location based on historical data. A behavior module interposed between and communicatively coupled to the reactive module and the deliberative module combines the reactive vehicle speed and the deliberative vehicle speed to arrive at a suggested optimal vehicle speed for fuel efficiency.
[0009] A vehicle control system of the present invention collects and analyzes real time and historical vehicular and environmental data to provide behavioral recommendations with respect to optimized fuel consumption. In addition to collecting and analyzing intrinsic data the system can also gather data from other vehicles with respect to their optimal fuel efficiency profiles for the same geographic location. This ancillary data is normalized and used to enhance the intrinsic calculations for behavioral recommendations.
[0010] In another embodiment of the present invention a method for managing fuel consumption of a vehicle includes collecting real time vehicular and environmental data, as well as determining a location for the vehicle, to determine a reactive vehicle speed for optimal fuel efficiency. In addition the method accesses historical vehicular performance data for the location of the vehicle to determine a deliberate vehicle speed for optimal fuel efficiency and then merges the reactive vehicular speed and the deliberate vehicle speed to ascertain an optimal vehicle speed for fuel efficiency.
[0011] Other aspects of the present invention include such things as the reactive module collecting real time data about a plurality of vehicle and environmental characteristics. These characteristics can include vehicle weight, temperature, tire pressure, road condition, and barometric pressure.
[0012] Moreover the deliberative module ideally analyzes and applies historical vehicular performance data of the vehicle for the particular location but can use pre-established non-location specific performance data. The deliberative module can also analyzes and apply historical vehicular performance data of other vehicles at the particular location.
[0013] The behavior module of the present invention suggests, in one embodiment, an optimal gear selection and other techniques for fuel efficiency. As mentioned, the system is operable to communicate data among two or more vehicles including the reactive vehicle speed for optimal fuel efficiency and the deliberate vehicle speed for optimal fuel efficiency. By doing so vehicles share historical vehicular performance data for a plurality of particular locations. The behavior module is operable to modulate the reactive vehicle speed based on data received from other vehicles within a predetermined proximity of the vehicle and suggest an optimal vehicle speed for fuel efficiency is based on a collaborative calculation among the other vehicles within the predetermined proximity of the vehicle.
[0014] The features and advantages described in this disclosure and in the following detailed description are not all-inclusive. Many additional features and advantages will be apparent to one of ordinary skill in the relevant art in view of the drawings, specification, and claims hereof. Moreover, it should be noted that the language used in the specification has been principally selected for readability and instructional purposes and may not have been selected to delineate or circumscribe the inventive subject matter; reference to the claims is necessary to determine such inventive subject matter.

Description of the Invention
[0022] A vehicle control module collects and analyzes real time and historical vehicular and environmental data to provide behavioral recommendations with respect to optimized fuel consumption. According to one embodiment of the present invention, a vehicular control module monitors and collects real-time vehicular and environmental data to construct an optimal speed/behavior profile that is reactive to current conditions. As the system determines that the vehicle can be operated in a manner that is more fuel efficient, recommendations on how to do so are presented to the user. Simultaneously, a deliberative fuel consumption profile is constructed based on historical data tied to the current location of the vehicle. The current conditions and user interaction with the vehicle with respect to fuel consumption are compared to historical data with respect to the same location. Using this data a determination can be made whether, based on current conditions, and historical data, a recommendation can be presented to the user as a means by which to modify current operating methodology to optimize fuel consumption.
[0023] In one embodiment of the present invention, a deliberative policy module also interacts with other nearby vehicles to gain normalized data pertinent to the determination of optimized fuel efficiency. For example the operation of truck versus a car with respect to optimized fuel efficiency on the same segment of road may be vastly different. But both optimized solutions may be based on one or more common considerations. By sharing universally applicable data, a vehicle that has never traversed a particular segment of highway or traveled that route an insufficient number of times to individually develop meaningful data can benefit from vehicles that have traveled the same segment numerous times. And while some of the data is vehicular specific, other portions of the data can be universally applicable to all vehicles. This universal data is conveyed in an abstract format and used to provide to the user a deliberative optimized fuel consumption profile that when combined with the reactive profile, provides the user with useful behavioral recommendations.

[0034] As described with reference in addition to FIG. 1 , vehicular management system 100 includes a vehicle control module 110 communicatively coupled to a plurality of sensors 140, a reactive adaptation module 120, and a deliberative policy module 130. Taking data collected by the plurality of sensors 140 and the recommendations provided by the reactive adaptation model 120 and the deliberative policy module 130, the vehicular control module 110 works with the driver behavior module 150 to provide user recommendations as to how to operate the vehicle to produce optimal fuel consumption.
[0035] According to one embodiment of the present invention the vehicle control module 110 is communicatively coupled to a plurality of sensors 140 that can convey data relating to the global position of the vehicle, native vehicle data such as fuel flow delivered to the engine, operating temperature, oxygenation, barometric pressure with respect to engine operation, tire pressure, gear selection in gear ratio, gross vehicular weight, vehicular configuration (status of windows and/or roof components) and the like. One of reasonable skill in the relevant art will appreciate that any of these factors alone or in combination may significantly affect fuel consumption. For example, having the windows down while driving at highway speed increases drag while operating the vent system may maintain the interior temperature without a incurring a “fuel expense”. Additional sensors that are coupled to the vehicular control module 110 can also provide environmental data including air temperature, surface temperature, relative humidity, inclination, road conditions, relative wind speed, and other factors that may affect the performance of the vehicle. Driving on a dirt or gravel road is not as efficient as on a paved surface, just as a snow packed road, while reducing friction, makes the operation of the engine less efficient.
[0036] The vehicular control module 110 in conjunction with the reactive adaptation module 120 applies advanced computational intelligence methods to the collected data in real-time to extract valuable information with respect to the vehicle and the environment and, by identifying significant behavioral patterns while removing outliers, constructs a fuzzy model regarding optimize fuel consumption. The reactive adaptation model 120 adjusts the determination of an optimal speed for fuel efficiency based on current conditions and recent data feedback from the vehicular sensors and any user inputs. By contrast the deliberative policy module 130 uses historical data associated with the current route and past user interaction so at to determine historical optimal performance.
[0037] For example, assume a sedan equipped with a plurality of sensors and the capability of the invention described herein is traveling along a particular segment of highway. As the sedan travels down the highway, sensors continually collect information with respect to the fuel flow to the engine, the operating temperature of the engine and its characteristic operation, tire pressure, gear ratio and gear selection, the configuration of the vehicle with respect to whether the windows are rolled up or down or in the case of a convertible if the top is up or down, and other native characteristics of the vehicle. Using this information, a real-time consumption of fuel with respect to the distance traveled, a.k.a. miles-per-gallon (mpg), can be calculated and displayed. Just as in many versions of vehicles currently on the road, and is well known in the prior art, a display of the real-time current miles-per-gallon to be presented to the user as an indication of how much fuel is being used.
[0038] According to one embodiment of the present invention, the information collected by the vehicle control module 110 is conveyed to the reactive adaptation module 120 which determines whether the current operation of the vehicle optimizes fuel consumption and how minor modifications to user behavior or configuration can improve fuel efficiency. When the sedan is operating at a speed at which fuel consumption can be optimized by either traveling faster or slower, such an indication is presented to the user as an action by which to optimize fuel consumption. For example, perhaps based on the weight of the sedan an increase in the tire pressure by 5 pounds/inch can provide a 5% increase in fuel economy. Further and for the purposes of this example, assume the sedan is traveling on a slightly inclined paved roadway with dry road conditions and a 10 mile an hour headwind. Also assume that there are no legal restrictions to either decreasing or increasing the vehicle speed so as to optimize fuel consumption. One of reasonable skill in the relevant art will recognize that in certain circumstances, achieving an optimal fuel consumption speed profiled may violate governmental regulations or safety parameters.
[0039] In this circumstance, the user may typically set the sedan to travel at 50 mph resulting in a fuel economy of 20 miles per gallon. However, in this circumstance with a slightly inclined road and in tailwind a more optimized miles per gallon may be obtained at 55 mph. The increase in speed may be attributed to the decreasing wind resistance due to the tailwind, and a lower than normal gross weight of the vehicle. According to one embodiment of the present invention, a user interface 160 such as a display indicator on the odometer will provide immediate feedback to the user to increase his speed so as to reach optimal fuel consumption or a simply message that indicates to the user that by increasing their speed to 55 mph, if safe and legal to do so, the user may increase fuel economy from 20 miles-per-gallon to 22 miles-per-gallon. One of reasonable skill in the relevant art will appreciate that if the user simply turns the car around and travels over the same segment of road in the opposite direction, the speed at which an optimal fuel consumption occurs will be different than that described above. For example, the tailwind would now be a headwind and the inclination of the highway would now be a declination. Accordingly, the computation of the speed at which to achieve optimal fuel consumption and associated recommendations would likely differ.
[0040] Another aspect of the present invention is the incorporation of a deliberative policy with respect to optimal fuel consumption. While the reactive adaptation module 120 provides the user with real-time feedback with respect optimal fuel consumption, the present invention also stores current information with respect to fuel consumption as associated with a particular segment of highway or similar positional data for later analysis and use. The deliberative policy module 130 retrieves historical data from memory 135 regarding fuel consumption and vehicle characteristics to determine behavioral responses which have historically provided optimal fuel consumption and to provide a datum by which to compare the current state so as to arrive at a determination of whether there exists the possibility that fuel efficiency can be improved. Accordingly these historical behavioral responses are merged with the reactive real-time recommendations to provide to the user a much more comprehensive and useful recommendation.
[0041] For example, consider the same sedan traveling down a segment of highway which is frequently traveled by the user. The segment of highway is paved, possesses a dry road condition, and has a declination angle of approximately 5°. In a normal situation with calm wind, assume that the optimal speed for this section of highway as determined by the reactive adaptation module would be 55 mph. If the user is currently traveling at 30 mph the reactive adaptation module 120 would display a recommendation to the user to increase his speed to 55 mph. However the deliberative policy module 130, recognizing that the vehicle is on a segment of highway which has been frequently traveled, calculates based on the position of the vehicle that it is highly likely the vehicle will come to stop within the next half mile and a more accurate optimal speed is 45 mph. This conclusion is based on historical data of the sedan traveling on the same segment of highway in the past. For example, perhaps either a stoplight or stop sign normally restricts travel in this particular segment of highway. Alternatively traffic may suggest that a particular time of day the optimal speed of 55 mph is not realistically possible. Regardless of the circumstances that surround the historical data, the deliberative policy module determines that an optimal fuel consumption speed is, for example, more accurately 45 mph for the next 2 miles followed by 50 mph for the next 5 miles. Depending on how robust the data from which the deliberative policy module had made its determination, the vehicular control module merges the recommendations from the reactive adaptation model and the deliberative policy module to arrive at a final recommendation presented to the user. In this case, as the deliberative policy module possesses substantial data identifying the likelihood that the vehicle will stop with the next half mile, the vehicular control module overrides the reactive adaptation module's recommendation and presents to the user a recommendation for optimal fuel consumption more aligned with that produced by the deliberative policy module.
[0042] Another aspect of the present invention, and specifically the deliberative policy module operation, is the ability to collect and utilize historical data from other vehicles. Using a wireless transmission capability embedded within the vehicles or a capability added to the vehicle as an aftermarket product, the deliberative policy model of one vehicle can wirelessly communicate and transfer data to a deliberative policy module of another vehicle. According to one embodiment of the present invention, data collected and stored by each vehicle is normalized so as to be applicable to any vehicle. When another vehicle comes within communication range, and communication protocols are exchanged, a communication relationship is established and normalized vehicle performance data for a particular position of interest is transferred. Normalized vehicular data may include information with respect to typical speed profiles for particular time of day (taking into account traffic and other delays which may not be otherwise physically) and for certain segments of highway. For example, an optimal fuel consumption profile for a large truck may indicate that from 4 PM to 6 PM on a certain segment of highway the optimal fuel consumption speed is 30 mph requiring a lower gear ratio and other certain configurations. Although this speed configuration and recommendation may not apply to a sedan, it nonetheless conveys important information with respect to the position and optimal speed determination for a certain period of time. Moreover the truck may indicate that for a particular location a certain gear selection provides an optimal fuel consumption profile. While the gross weight and particular gear selection of the truck is irrelevant to the sedan, a normalized reading of the same data may indicate to the sedan that a lower, sedan specific, gear selection may produce an optimize fuel consumption based on a gross weight analysis of the sedan. That, combined with the reactive adaptation module recommendation, produces a speedy recommendation for optimal fuel consumption.
[0043] According to another embodiment of the present invention, the recommendation prompted by fuel consumption is integrated with a behavior model which recognizes individualistic user patterns and produces a fuzzy logic recommendation for optimal fuel consumption. The behavior module recognizes differing user input and, based on historical data and ancillary considerations, produces a fuzzy logic model to simulate typical user patterns that can be adjusted so as to achieve better fuel efficiency.
[0044] In other embodiments of the present invention the deliberative policy module, in conjunction with the vehicular control module, can suggest alternative routes to a desired destination that provides optimized fuel consumption. The navigation systems of most vehicles can provide a “fastest route” to destination, the present invention incorporating historical and reactive data, can provide the user with a route to destination that minimizes fuel consumption. Parameters can be set such that a route that suggests minimal fuel consumption is limited to delay arrival by no more than a predetermined period of time and that any route that delayed arrival beyond that delay be rejected. In another embodiment the system and be set to default to a route that offers optimal fuel consumption but minimally affects arrival time. The result may, for example, be that the route suggested is less hilly, less congested, or with fewer traffic controls, so as to provide the vehicle with the best opportunity to maximize fuel efficiency. The user can then select the route not only based on fastest arrival time but one that would optimize fuel efficiency as well.
[0045] FIG. 2 is one method embodiment for vehicle management by which the reactive adaptation module can arrive at an optimal fuel consumption profile. The determination of a reactive optimal fuel consumption speed begins 205 with a collection of real-time vehicular performance data 210. In addition to collecting native vehicular data, the present invention collects real-time environmental data 220. This data may include things such as temperature, barometric pressure, relative humidity, relative wind, and the like. Data with respect to the current fuel consumption is obtained based on the current engine performance 230. The current fuel consumption is associated with the current location as provided by a global positioning system or similar positional data. Based on the collected vehicular data and environmental data, a reactive optimal fuel consumption profile 280 is produced.
[0046] Simultaneously, and as shown in FIG. 3 , the deliberative policy module 130 determines a deliberative optimal fuel consumption profile by using historical data associated with the current location of the vehicle. The process begins 305 with the determination of the vehicle's current position 310. Based on that position, historical data regarding fuel consumption is retrieved from memory 320. Optionally, third-party data regarding fuel consumption also associated with the same position is retrieved and locally stored 340. Based on the retrieved historical data from both the internal memory system of the vehicle and from historical data collected from third parties, a deliberative optimal fuel consumption profile for a particular location is determined 360.
[0047] The reactive optimal fuel consumption profile and deliberative optimal fuel consumption profile are combined by process shown, in one embodiment, in FIG. 4 . Such a process begins 405 with the determination of whether sufficient data exists to create a deliberative fuel consumption profile 410 and whether the vehicle is currently performing at optimal fuel efficiency 420 according to the reactive optimal fuel consumption profile. In no deliberative policy is available and the vehicle is substantially operating at its optimal fuel efficiency the process ends 495. If, however, the determination is made that the vehicle is traveling at a speed other than that which optimal fuel consumption can be achieved, system suggests 425 behavioral changes consistent with the optimal fuel consumption profile developed by the reactive module. (note this is in the instance in which there is insufficient data to develop a deliberative policy profile)
[0048] If a deliberative fuel consumption profile exists, it is retrieved 430 as is the reactive optimal fuel consumption profile and they are compared 440 to determine if based on the deliberative profile the reactive recommendation can be further modified. The reactive optimal fuel consumption profile and the deliberative optimal fuel consumption profile are combined 450. In situations in which a significant amount of historical data is available and the deliberative profile substantially differs from the reactive profile, the deliberative fuel consumption profile and the reactive fuel consumption profile are combined 450 to produce a recommended optimal fuel consumption profile. Alternatively, in situations in which historical data is lacking or is possesses questionable relevance based on current conditions, the reactive fuel consumption profile can be favored. For example, while deliberative fuel consumption profile may exist and may be associated with conditions which are not consistent with those being experienced by the current vehicle. Conditions such as the gross weight of the vehicle, vehicle configuration, road conditions, and other real-time factors may diminish the importance of deliberative fuel consumption profile. Once produced, the recommended optimal fuel consumption profile is presented 460 to the user to initiate behavior modifications.
[0049] Another aspect of the present invention is to associate the movement of two or more vehicles that are proximal to each other and traveling in the same direction or on the same route so as to produce optimal fuel consumption for each vehicle. A convoy handler module (not shown) enables two or more vehicles to travel along the same route and operate as a collaborative unit so as to optimize combined fuel consumption. By communicating various parameters including each determined reactive and deliberative optimal speed profiles between vehicles and data with respect to the movement of the entire convoy each vehicle can provide recommendations to each user as how to optimally react and control their individual vehicle. Accordingly, information such as convoy and vehicle speed, gear selection, fuel use, and the like can be transmitted among the vehicles so as to preclude accordion like behavior which is detrimental to fuel efficiency. In one embodiment of the present invention each vehicle in a convey can be equipped with ultra wide band frequency tag or similar technology which not only identifies which local vehicles are in a particular convey but enable a more robust and reliable communication of information. The information conveyed between vehicles can be used to develop a spatial understanding and relative positioning that can have synergistic effects with respect to pace, range, speed and other factors that can affect aggregate fuel consumption. This communication can be used to coordinate activities and behaviors.
[0050] For example, information conveyed in a designated convey can indicate that while fuel efficiency would be increased for 3 of 5 vehicles by increasing speed 10 mph, the result would dramatically reduce the efficiency of the remaining two vehicles. A more efficient aggregate speed, while not optimal for any one vehicle, may nonetheless result in a lower overall consumption of fuel.
[0051] In other embodiments of the present invention, the reactive and the deliberative modules can be linked to real-time traffic control modules to optimize speed so as to match certain regulatory and certain traffic control signals that minimize stop and go operation and therefore optimize fuel efficiency. Such information can be used to modulate the speed by the operator to ensure that the vehicle reaches each stoplight with sufficient time so as to proceed without stopping.
[0052] The present invention focuses on the determination of optimal performance based on internal vehicle performance, external environmental characteristics and historical positional data. By collaboratively combining native data with respect to a vehicle, external and environmental data and positional data, a speed at which to achieve optimal fuel efficiency can be recommended to the user. Moreover, the present invention can utilize recorded behavioral characteristics and fuzzy logic to provide a recommendation to the user that needs user characteristics while still optimizing fuel consumption. The invention described herein enables vehicle operators to modify their behaviors to optimize efficiency by communicating insights regarding optimal speed, gear selection, acceleration/deceleration, alternative routes, and the like. These insights are based on the analysis of a wide range of factors that individually and collectively affect performance. While the invention described herein is applicable to the consumption of fossil fuels, it can be equally applied to the consumption of electricity or vehicles possessing hybrid technology. For example, it may be more optimal to utilize battery resources for electrical vehicles to climb a hill and then regenerate the battery during braking descents, as opposed to charging the battery using an engine during an ascent and wasting braking energy during descent.
