METHOD AND SYSTEM FOR AUTHENTICATING VEHICLE EQUIPPED WITH PASSIVE KEYLESS SYSTEM
First Claim
1. A method for authenticating a vehicle equipped with and a passive keyless system that includes a vehicle module configured to communicate with a portable keyfob, the method comprising the steps of:
- sending one or more initial challenge signal(s) from the vehicle module to the portable keyfob in response to a passive keyless start attempt of the vehicle, the initial challenge signal(s) being sent before a successful passive keyless start of the vehicle;
sending one or more secondary challenge signal(s) from the vehicle module to the portable keyfob in response to a trigger event, the secondary challenge signal(s) being sent after a successful passive keyless start of the vehicle;
initiating an active authentication to confirm the presence of an authorized driver in the vehicle when a valid response to the secondary challenge signal(s) is not received by the vehicle module; and
performing one or more remedial action(s) if a valid response to the active authentication is not received.

13. A method for authenticating a vehicle equipped with and a passive keyless system that includes a vehicle module configured to communicate with a portable keyfob, the method comprising the steps of:
-
initiating passive authentication of the keyfob following a passive keyless start of the vehicle and in response to a trigger event; determining if an authorized driver is present in the vehicle when a predetermined number of attempts to passively authenticate the keyfob have failed, wherein determining if an authorized driver is present includes sending one or more prompt(s) requiring a valid active-response from an authorized driver and/or an authorized wireless device; and performing one or more remedial action(s) if a valid active-response is not received. - View Dependent Claims (14, 15, 16, 17, 18)

19. A system for authenticating an authorized driver of a vehicle, the system comprising:
-
at least one vehicle system module configured to detect one or more moving vehicle trigger(s); and a passive keyless start system including a vehicle module configured to wirelessly communicate with, and to passively authenticate, a portable keyfob in response to detecting at least one of the moving vehicle triggers, the passive keyless start system is configured to; determine if an authorized driver is present in the vehicle when a predetermined number of attempts to passively authenticate the keyfob have failed, wherein determining the presence of the authorized driver includes sending one or more prompt(s) requiring a valid active-response from an authorized driver and/or an authorized wireless device; and initiate one or more remedial action(s) in response to determining that no authorized driver is present. - View Dependent Claims (20)
