Patent ID: 8344869

Claim:
A vehicle system comprising: tire sensors mounted in, on or adjacent respective tires of the vehicle, each tire sensor being configured to transmit a signal and to detect an LF field; low frequency (“LF”) antennas including a door-mounted antenna mounted on a door of the vehicle, each LF antenna being configured to transmit an LF tire sensor wake up field to wake up respective tire sensors; a receiver mounted on the vehicle configured to receive signals transmitted from the tire sensors; a door switch associated with the door having the door-mounted antenna mounted thereto, the door switch being configured for determining whether the door is open; and an electronic control unit (“ECU”) in communication with the antennas, the receiver and the door switch, wherein the ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals, and wherein the ECU is further configured to: (1) disregard signals received from the tire sensors woken up by the door-mounted antenna when the door was open, or (2) inhibit the door-mounted LF antenna from transmitting the LF field to wake up the tire sensors when the door is open.
