AUTHENTICATION ARRANGEMENT AND SYSTEM FOR A MOTOR VEHICLE

Abstract

An authentication arrangement for a motor vehicle includes an immobilize transponder, a first reception device, a control device and, optionally, a transmission and reception device. The immobilize transponder is switchable at least between an active operating state, which causes deactivation of the engine immobilizer, and an inactive operating state. The control device is designed to respond to a prescribed control signal captured by the first reception device by outputting a switching signal for switching the operating state of the immobilize transponder to the active operating state. An authentication system and a use of the authentication system are also disclosed.

Description

[0062] In the drawings:

[0063] FIG. 1: Design of an authentication arrangement as a system arranged on the motor vehicle;

[0064] FIG. 2: Design of an authentication arrangement as a portable ID transmitter with mechanical motor vehicle key;

[0065] FIG. 3: Design of an authentication system.

[0066] In FIG. 1, a motor vehicle 2 is shown, which has an authentication arrangement 1. In the example of FIG. 1, the authentication arrangement 1 is a portable ID transmitter which is stored in the motor vehicle 2. The authentication arrangement 1 has an immobilize transponder means 3, which can be controlled by a control means 6. The control means 6 is coupled to a first reception device 5, which is designed, for example, as a BLE interface. Furthermore, the authentication arrangement 1 also has a transmission and reception device 13, which is designed as an LF/HF transmission device and is provided for communication of the ID transmitter with a motor vehicle-side control device 4 to provide a Keyless Go or Passive Entry Passive Start functionality. The immobilize transponder means 3 further comprises a virtualized crypto-chip, which is coupled to transmission and reception means 3 and acts together with these as a crypto-chip transponder. The transmission and reception means 3 are designed as passive transponders.

[0067] The first reception device 5 designed as a BLE interface is set up to perform a BLE communication with a smartphone. The smartphone is equipped with a suitably provided app capable of transmitting the predetermined control signal to the first reception device 5 by radio communication. After receipt by the reception device 5, the control signal is verified by means of control means 6. The verification can be done, for example, by using a symmetrically encrypted communication between the smartphone and BLE interface, which is carried out as part of a coupling or the establishment of the BLE connection (pairing) between the smartphone and the BLE interface 5. Once the control means 6 acknowledges receipt of the predetermined control signal, the control means 6 initiates the emulation of the virtualized crypto-chip, thereby placing the immobilize transponder means in the active operating state. By switching the immobilize transponder means into the active operating state, the deactivation of an engine immobilizer 4 of the motor vehicle is brought about.

[0068] FIG. 2 shows another embodiment of an authentication arrangement. The authentication arrangement 1 of FIG. 2 has in particular a key bit 7. The operator is thus given the opportunity to operate the motor vehicle with the key bit 7 by means of the mechanical operation of a lock, such as a door lock or an ignition lock. The operation is successful in this case only when the immobilize transponder means 3 is activated, which is done by a switching signal which is output in response to the receipt of a predetermined control signal whose authenticity is confirmed by the control means 6. The remaining constituent parts of the authentication arrangement 1 shown in FIG. 2 correspond to the elements shown in FIG. 1.

[0069] An embodiment of the authentication system 18 is shown in FIG. 3. The authentication system 18 has a base station 12, which is designed as a lockable box in the embodiment shown. The base station 12 is arranged undetachably within the motor vehicle 2 by means of an adhesive connection 14a, 14b. An authentication arrangement 1 is positioned within the lockable box, wherein said arrangement is designed as a portable ID transmitter having an additional mechanical key bit 7 according to the exemplary embodiment shown in FIG. 2. The ID transmitter has a transmission and reception device 13, which is designed as an LF and HF interface. With an LF antenna of the LF and HF interface, the ID transmitter receives corresponding polling signals of the motor vehicle. Then, the ID transmitter enters a bidirectional HF radio communication with the vehicle-mounted control unit. As part of this bidirectional exchange, the authentication of the ID transmitter is performed on the motor vehicle. After successful authentication, the operator is granted access to the motor vehicle and access to the operation of the motor vehicle. The ID transmitter 1 is set up such that the readiness of the ID transmitter 1 for radio communication with the vehicle-side control unit corresponds to the delivery state of the ID transmitter 1. The ID transmitter 1 has an immobilize transponder means 3, 3 with which an engine immobilizer of the motor vehicle 2 can be deactivated. The switching on and off of the immobilize transponder means 3 occurs by means of the output of a switching signal by the control means 6 of the ID transmitter 1. The switching signal is output when the control means 6 detects the receipt of a predetermined control signal by the first reception device 5. The control signal, which is received by the first reception device 5, comes from the transmission device 9.

[0070] The prerequisite for a transmission of the control signal by the transmission device 9 is again the receipt of a corresponding activation signal 11 by a radio device 10. In the illustration shown, a smartphone 15 is used for the emission of the activation signal 11, on which a suitably prepared app is installed. With the app, a rental agent of the motor vehicle enables the transmission of the authorizing activation signal 11, which is transmitted via a Bluetooth connection to the radio device 10 of the base station 12. A computing unit 10 of the base station 12 evaluates the activation signal 11 after receipt. If the computing unit 10 recognizes the activation signal 11 received from the radio device 10 as authorizing, the transmission device 9 initiates the transmission of the predetermined control signal. The control signal is then received by the first reception device 5 of the ID transmitter 1 and used in the manner described above for deactivating the engine immobilizer.
