  • Patent number: 10504373
    Abstract: A system for locating a vehicle utilizing a zone posts in known locations that when the vehicle comes within a proximity of the zone post receives an identification signal from the vehicle and sends that identification signal on to a central command center. The identification signal may be provided by a dongle or a tire pressure monitoring system tire pressure sensor. The central command center may be queried with vehicle identifying information, and the location of the zone post that last sent the identification signal is provided as an indication of the location of the vehicle.
