Abstract:
A method is provided for authenticating a transceiver in a keyless entry system for a vehicle. The method uses a collision avoidance radar system on the vehicle for authenticating a key fob radar transceiver. A lower power radar signal is transmitted from the vehicle. The lower power radar signal is transmitted below an ambient noise level to make the radar signal difficult for an attacker to detect. The key fob transceiver is then authenticated as being a legitimate transceiver for accessing the vehicle using the low power radar signal. A distance bounding scheme may be used to determine if the key fob is within a predetermined distance. Challenge/response communications may be used to authenticate that the key fob is the legitimate key fob.

Claim (Index 17):
The method of  claim 16 , wherein transmitting a low power radar signal from the vehicle further comprises:\n transmitting a first low power radar signal from a first transmitter fixed at a first location on the vehicle; and transmitting a second low power radar signal from a second transmitter fixed at a second location on the vehicle, the first location being different than the second location.
