    Abstract: A passive entry passive start (PEPS) vehicle security system configured to thwart a relay attack on the system. The system includes one or more ultra wideband transceivers (UWBX) installed on a vehicle and configured to transmit a request pulse at a request time. A mobile UWBX, possibly installed in a nomadic device such as a smart phone, is configured to transmit a reply pulse in response to the request pulse. A controller is configured to determine a distance between each UWBX and the mobile UWBX based on a time interval between the request time and a time that corresponds to when the reply pulse is received by the each UWBX. The controller may also be configured to unlock doors of the vehicle only if the distance is less than an unlock threshold.

    Abstract: A method of operating a tire pressure monitor system on a vehicle to determine a wheel location of wheels equipped with pressure sensors. The method includes equipping a plurality of wheels with a pressure sensor, determining a plurality of pressure values from each pressure sensor, detecting a variation of the pressure values from a plurality of pressure sensors, and determining a wheel location based on a comparison of the variations of the pressure values. Variations useful for determining wheel location may include running over an object such as a rumble strip or pot-hole on the roadway, or the vehicle executing a turn.

    Abstract: A passive entry passive start (PEPS) vehicle security system configured to activate a vehicle function when an activation signal is received. The system includes a nomadic device configured to detect a change of a magnetic field relative to the nomadic device, and emit an activation signal only if the change corresponds to walking by an operator carrying the nomadic device.
