Method and system for confirming the identity of a vehicle

Abstract

A system for confirming the identity of a vehicle. The device includes: a vehicle control unit in the vehicle to be identified; a vehicle identification device; an external service device designed to interact with the vehicle; a vehicle sensor in the vehicle; and an external sensor. The vehicle identification device establishes a data connection with the vehicle control unit and triggers a physical interaction between the vehicle control unit and the external service device. The vehicle sensor detects the physical interaction and transmits a corresponding vehicle detection value to the vehicle identification device. The external sensor detects the physical interaction and transmits a corresponding external detection value to the vehicle identification device; and the vehicle identification device compares the vehicle detection value and the external detection value with one another and confirms the identity of the vehicle if the two detection values coincide with one another within a predefined tolerance.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

(4) FIGS. 1 and 2 each show in a schematic representation a system 1 for confirming the identity of a vehicle 2 according to one exemplary embodiment of the present invention.

(5) System 1 includes a vehicle control unit 4 installed in the vehicle to be identified as well as a vehicle identification device 10.

(6) Vehicle control unit 4 and vehicle identification device 10 are connected to one another via a data connection 8. Data connection 8 may be a hardwired data connection 8 or a wireless data connection 8. Data connection 8 may, for example, be established via mobile transceiver device (Dongle) 7, which is inserted into an OBD socket 5 of vehicle 2. Alternatively, transceiver device 7 may be permanently integrated into vehicle control unit 6 for establishing data connection 8.

(7) System 1 further includes an external service device 12, which is designed to physically interact 15 with vehicle 2. External service device 12 may, for example, be a current charging station 12 for charging a rechargeable battery 6 installed in vehicle 2 designed as an electric vehicle, or a fuel pump 12 for refueling a fuel tank 6 installed in vehicle 2 (see FIG. 1). Service device 12 may also be an exhaust gas measuring device 12 for measuring exhaust gases 13 of vehicle 2 (see FIG. 2).

(8) An external sensor 14, present at or in external service device 12, is designed to measure physical interaction 15 between external service device 12 and vehicle 2, for example, the electric current flowing from a charging station 12 to a rechargeable battery 6 in vehicle 2, the fuel flowing from a fuel pump 12 into a fuel tank 6, or exhaust gases 13 emitted by vehicle 2.

(9) A vehicle sensor 16, installed in vehicle 2, is also designed to measure physical interaction 15 between external service device 12 and vehicle 2, for example, the electric current flowing from a charging station 12 to a rechargeable battery 6 in vehicle 2, the fuel flowing from a fuel pump 12 into a fuel tank 6, or exhaust gases 13 emitted by vehicle 2.

(10) To confirm the identity of vehicle 2, vehicle identification device 10 establishes data connection 8 with vehicle control unit 4. Once data connection 8 has been established, a physical interaction 15, for example a fueling or charging process, is triggered by vehicle identification device 10 via data connection 8 between vehicle 2 and external service device 12. Physical interaction 15 may also include the operation of an engine of vehicle 2 at a predefined rotational speed.

(11) Vehicle sensor 16 also detects physical interaction 15, for example, the current transmitted to vehicle 2, the quantity of fuel flowing into fuel tank 6 of vehicle 2, or exhaust gases 13 emitted by the engine of vehicle 2, and vehicle control unit 4 transmits via data connection 8 a vehicle detection value determined in this manner to vehicle identification device 10.

(12) External sensor 14 also detects physical interaction 15, and external service device 12 transmits a detection value determined in this manner to vehicle identification device 10.

(13) Vehicle identification device 10 compares the vehicle detection value with the external detection value and confirms the identity of vehicle 2 if the two detection values coincide with one another within a predefined tolerance.

(14) Vehicle control unit 4 and/or vehicle identification device 10 may also be connected to a database/cloud 20, which contains pieces of information about vehicle 2.

(15) Database/cloud 20 may, for example, contain identification data and/or keys, which enable vehicle identification 10 to identify vehicle 2 and/or vehicle control unit 4 and/or to communicate with vehicle control unit 4 via an encrypted data connection 8.

(16) Database/cloud 20 may further be designed to document and/or to bill the service performed by service device 12, for example, the current or fuel supplied by service device 12 to vehicle 2.

(17) Database/cloud 20 may also contain pieces of information about the locations of service devices 12, in order to enable vehicle control unit 4 to establish a data connection 8 with the nearest service device 12.

(18) In one exemplary embodiment of the present invention, service device 12 also includes a camera 18, which makes it possible to record at least one image of vehicle 2 if it is located in the surroundings of service device 12, and to transmit the image data to vehicle identification device 10. Vehicle identification device 10 may store the image data supplied by camera 18 together with the data measured by external sensor 14 for purposes of documentation and/or may prompt the owner of vehicle 2, for example, via his/her smartphone, to identify his/her vehicle 2 based on an image of vehicle 2 recorded by camera 18 and presented to the owner of vehicle 2, and to authorize planned physical interaction 15, for example, the charging, fueling or exhaust gas measuring process.

(19) The triggering of physical interaction 15 between vehicle 2 and service device 12 may take place directly via vehicle control unit 6 as it was previously described.

(20) In one alternative embodiment of the present invention, vehicle identification device 10 and/or vehicle control unit 6 may influence at least one sensor 22 of a driver assistance system 24 installed in vehicle 2, in order to prompt driver assistance system 24 to trigger desired physical interaction 15.

(21) Load changes for the diagnosis may also be triggered in vehicle 2 in parallel to the triggered service. In addition, additional off-board and on-board diagnostic processes may be started and varied via data connection 8 and may be comprehensively compared with other data, classified and evaluated in detail in database/cloud 20. Additional services such as, for example, the reading out of data loggers in vehicle 2 or the flashing of software of vehicle control unit 6 may also be offered.

(22) FIG. 3 shows a further exemplary embodiment of a system for confirming the identity of a vehicle in accordance with the present invention. The features that coincide with those shown in FIGS. 1 and 2 are provided with the same reference numerals and are not described again in detail.

(23) In the exemplary embodiment shown in FIG. 3, the feedback of vehicle control unit 6 to vehicle identification device 10, i.e., the transmission of the data measured by vehicle sensor 16 does not take place via the previously described direct data connection 8 between vehicle control unit 4 and vehicle identification device 10, but via a cloud 9, in particular, a cloud 9 of the vehicle manufacturer. The use of a cloud 9, in particular, of a cloud 9 of the vehicle manufacturer, increases the reliability of the method, since the identity of vehicle 2 and/or the identity of vehicle identification device 10 may be checked and confirmed by the vehicle manufacturer.
