Abstract: A relay attack deterrence system includes a mobile platform including a plurality of mobile platform transmitter components and a mobile platform receiver component provided therein. The system further includes a fob device having a fob receiver component, a fob transmitter component, and a motion sensor component configured to produce motion information. The fob device is configured to receive, at the fob receiver component, one or more first signals from at least one of the plurality of mobile platform transmitter components and to selectably transmit, to the mobile platform receiver component, a second signal based on the motion information and position information derived from the one or more first signals.

Abstract: Methods and apparatus are provided to dynamically configure a passive entry, passive start system to issue passive and active commands upon authentication of a remote keyless fob with a body control module in a given vehicle selected from a fleet of vehicles. In particular, a UID secret key data field is generated in the FOB data store using a fleet secret key data field and a vehicle secret key field retrieved from the BCM data store. A wakeup pattern data field stored in the FOB data store is generated with a fleet wakeup pattern data field and a master wakeup pattern data field retrieved from the BCM data store such that an approach wakeup pattern data field stored in the BCM data field is written to an approach wakeup pattern data field in the FOB data store when the remote fob is authenticated with the body control module.
