Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 6 illustrate a vehicle identification and information system indicated generally by the numeral 10.

The vehicle identification and information system 10 provides information on a particular vehicle 12 via an identification unit 14 including an emergency button 16 to both individuals in the area surrounding the vehicle 12 and to official vehicles such as police cars 18. The vehicle identification and information system 10 further includes a remote unit 20 positioned within the official vehicle 18 and a central computer 22 which communicates with the remote unit 20 for providing information regarding a particular vehicle 12 thereto. A remote control device 24 may also be operated by the user or owner 26 of the vehicle 12 for initiating the displaying of a distress signal such as "STOLEN" on a display unit 28 connected to the vehicle 12. The information displayed on the display unit 28 is to alert others in the vicinity of the vehicle 12 as to any situations or events involving the vehicle 12.

The vehicle identification and information system 10 is ideally included in every vehicle registered with the department of motor vehicles in every state in the country and the information is accessible from a central database or computer 22. When a vehicle 12 is manufactured the identification unit 14 is installed therein and upon sale of the vehicle 12 the necessary information such as that depicted on a display 84 as illustrated in FIG. 2 is input to the central computer 22. The necessary information includes an identification unit ID number 30, a vehicle license plate number 32, the state of vehicle registration 34, information regarding current registration 36 and insurance coverage 38 and a message regarding the status of the vehicle 40. Other additional information such as identification of the driver including address, telephone number and other identifying information may be stored within the central computer 22 for access by authorized personnel such as the police.

The central computer 22 communicates with the identification unit 14 in a particular vehicle 12 by wirelessly transmitting an information signal 44 thereto related to the status of the vehicle, e.g. "no insurance", "stolen", etc. and other pertinent information. The signal 44 is received by the identification unit 14 which displays the message on the display unit 28 from which the message can be viewed by persons in the vicinity of the vehicle 12. The owner 26 of the vehicle 12 is also supplied with a remote control unit 24 which can wirelessly transmit a signal 50 to the vehicle 12 to display a message on the display 28 indicating the vehicle 12 is stolen. The official vehicle 18 can also wirelessly transmit a signal 42 to the identification unit 14 indicating the vehicle is stolen. This signal may then be displayed on the display unit 28. This is in case the owner of the vehicle does not have a remote control device 24 or the vehicle 12 has been reported stolen. In order for the official vehicle to transmit the signal to the vehicle 12 a request signal would have to be transmitted to the central computer 22 requesting the identification number of the identification unit 14. The official vehicle 18 can also receive information regarding a particular vehicle 12 from the central computer 22 by transmitting an information request signal 46. This signal 46 would have to identify the vehicle 12 in some manner such as by including the license plate number of the vehicle 12. Upon receipt of this information request signal 46, the central computer 22 will transmit an information response signal 48 including the desired information for viewing on a display unit 84 within the official vehicle 18. If the information indicates the vehicle 12 is not registered as is indicated for vehicle 1 in FIG. 2 or uninsured as indicated for vehicles 1 and 4 of FIG. 2 the police can be alerted to this situation and stop the vehicle. Other information can be included such as the messages of column 40 which can indicate whether or not the vehicle should be stopped as for vehicle 3 of FIG. 2. This will alert persons in the area of the vehicle 12 as to the situation and thus take the appropriate action.

The internal components of the identification unit 14 are illustrated in FIG. 3. The identification unit 14 includes a microprocessor 52 connected to receive power from a power source 54 which may be the vehicle's 12 battery or a separate power source located within the vehicle 12. A memory 64 storing certain information regarding the vehicle 12 and identification unit 14 is connected to the microprocessor 52. A receiver 60 which receives signals transmitted from the central computer 22, the remote control unit 24 and remote unit 20 via an antenna 58 is connected to the microprocessor 52. The microprocessor 52 also receives signals from the emergency button 16 located within the vehicle 12. The microprocessor 52 analyzes the signals received from the receiver 60 and emergency button 16. The microprocessor 52 is also connected to the display unit 28 and transmits the analyzed information to the display unit 28 alerting persons in the vicinity of the vehicle 12 as to the current status of the vehicle 12. Information is also transmitted to the display unit 28 upon receipt of a distress signal from the remote control unit 24 or an alert signal received from either the remote unit 20, central computer 22 or remote control unit 24.

A preferred embodiment of the display unit 28 is illustrated in FIG. 4. The display unit 28 is preferably located on the tailgate of the vehicle 12 and displays the license plate number 64, the state of registration 66 and a message as to the vehicle's current status 68. The message may indicate that the vehicle 12 is "STOLEN" as in FIG. 4. Other messages include "PLEASE HELP" indicating the operator of the car needs assistance, "CALL POLICE" indicating a crime may be taking place, "HANDICAPPED" indicating the operator or a passenger in the vehicle is handicapped, or "DRIVE SAFELY" indicating all is well.

It is to be understood that the present invention is not limited to use of the message display 28 as described above. Any type of message display such as a display including a speaker system for producing an audio signal to thus draw additional attention to the vehicle in an emergency situation may be used and connected to the vehicle in any visible location. Thus, the message display 28 is able to communicate any desired message to persons in the vicinity and is not limited to the display as described above.

The internal components of the remote unit 20 are depicted in FIG. 5. The remote unit 20 includes a microprocessor 72. The microprocessor 72 receives power from a power source 74 such as the vehicle battery or another internally located power source. The remote unit 20 includes a transmitter 76 and antenna 78 for transmitting an emergency signal to the identification unit 14 in a particular vehicle 12 indicating the vehicle is stolen and an information request signal to the central computer 22. An information signal 48 is received from the central computer 22 in response to the information request signal 46 via a receiver 80 and antenna 82 combination. The information contained in the information signal 48 received from the central computer 22 is displayed on the display unit 84 for viewing by the requester. An exemplary display unit 84 is illustrated in FIG. 2. The requester is normally a government official using the official vehicle 18 such as a police officer. Also connected between the power source 74 and the display 84 is a temporary power button 86 for providing power to the display 84 for a period of time after the vehicle is turned off. Thus, the display 84 is visible for a period of time and thus can be viewed by a police officer or any person in the vicinity in case of an emergency situation.

The operation of the device and system will now be described with specific reference to FIG. 6. In step S2, a vehicle 12 is equipped with the identification device 14 including an emergency button 16 located within the vehicle 12 and a display device 28 located in a visible position on an outer side of the vehicle 12. The display 28 is preferably located on the tailgate of the vehicle 12. Upon registration of the vehicle 12 pertinent information regarding the vehicle 12 including identification of the driver and insurance information are input into the central computer 22 as described in step S4. Official vehicles 18 are then equipped with remote units 20 for receiving information on vehicles 12 equipped with the identification unit 14 as stated in step S6. Now the system 10 is in place and operating. An official vehicle 18 equipped with a remote unit 20 can now receive information regarding the registration status, insurance status, driver information and vehicle information on any vehicle including the identification unit 14.

As described in steps S8 and S10, the central computer 22 continually transmits an information signal to the identification unit 14 containing information on the identified vehicle 12. The information received from the central computer 22 is then displayed on the display unit 28 for viewing by persons in the vicinity of the vehicle 12.

Upon desiring to check the status of a vehicle 12, the official operating the official vehicle 18 transmits a signal to the central computer 22 requesting the information on the vehicle 12, as stated in step S12. The central computer 22 then transmits the information signal and any other emergency information back to the remote unit 20 as described in step S14. The requester is an official having clearance to obtain such information and is normally requesting the information from an official vehicle 18 equipped with a remote unit 20. Based upon the information received, an official utilizing the system will make a determination whether or not to stop the vehicle 12 as stated in step S16.

The remote control unit 24 may be activated by the owner 26 of the vehicle 12 to transmit a signal to the identification unit 14 indicating the vehicle 12 has been stolen as described in step S18. If the owner does not have a remote control unit 24, information indicating the vehicle 12 is stolen may be transmitted to the display unit 28 by the central computer 22 or by the remote unit 20 upon receipt of a report from the owner as stated in step S20. Upon receipt of the transmitted distress signal the identification unit 14 will display a message on the display 28 indicating the vehicle 12 has been stolen to alert both persons in the vicinity of the vehicle 12 and law enforcement personnel so they may take appropriate action in stopping the vehicle 12 as stated in step S22.

From the above description it can be seen that the vehicle identification and information system of the present invention is able to overcome the shortcomings of prior art devices by providing a vehicle identification and information system which is able to warn others as to an emergency situation in a vehicle and includes a central computer able to relay information to a police vehicle regarding the insurance status and record of any violations on a vehicle. The vehicle identification system is able to inform others if a vehicle has been stolen and provide other vehicle status information on the vehicle. The vehicle identification system also includes a switch which will inform others as to an emergency situation within the vehicle when activated even when the vehicle is traveling. Furthermore, the vehicle identification and information system of the present invention is simple and easy to use and economical in cost to manufacture.
