Abstract:
A portable ID transmitter for an authentication system of a vehicle includes a supply battery, a micro controller, UWB transmitting and receiving circuits controlled by the microcontroller for communication with a vehicle-side control device, and an LF receiving circuit controlled with the microcontroller for receiving LF wake-up signals transmitted in the LF frequency range, all arranged in a housing.

Claim (Index 12):
A method for operating a vehicle authentication system for authenticating a portable ID transmitter to the vehicle to enable vehicle functions for an operator carrying the portable ID transmitter,\n the authentication system comprising the portable ID transmitter and a vehicle authentication arrangement, the authentication arrangement comprising a plurality of UWB antennas having at least a first UWB antenna and a second UWB antenna spaced apart on the vehicle, the method comprising the following steps:\n A) selecting a UWB antenna from the plurality of UWB antennas of the authentication arrangement as the selected UWB antenna, wherein the UWB antenna is selected at least \n depending on a function of a reception signal strength of an LF signal transmitted between the ID transmitter and an LF interface of the authentication arrangement, and/or \n depending on a function of a reception signal strength of an HF signal transmitted between the ID transmitter and an HF interface of the authentication arrangement, and/or \n depending on a function of a proximity signal from a proximity sensor located on the vehicle; \n B) controlling the selected UWB antenna to perform UWB communication between the ID transmitter and the authentication arrangement; \n C) performing the UWB communication between the ID transmitter and the authentication arrangement; \n D) detecting a running time of a UWB signal of the UWB communication between the ID transmitter and the selected UWB antenna; \n E) checking whether the running time of the UWB signal is less than a predetermined maximum running time.
