Abstract
A passive entry passive start (PEPS) method for preventing relay attack includes detecting a distance of a wireless device to a vehicle based on a time of flight of an ultra-wideband (UWB) signal between the wireless device and a base station at the vehicle. The method further includes enabling by the base station a function of the vehicle only when the distance of the wireless device to the vehicle is within a zone of the vehicle.
