Abstract
A system and method for remote monitoring of vehicle tire pressure include monitors in each tire to transmit signals representative of tire pressure and receive control signals for use in regulating transmission of the tire pressure signals. A vehicle receiver receives the tire pressure signals and passive entry signals transmitted by a remote passive entry device. A vehicle transmitter transmits the control signals for use in regulating transmission of the tire pressure signals. A controller on-board the vehicle in communication with the receiver and transmitter conveys tire pressure information to a vehicle occupant based on the tire pressure signals, determines whether the vehicle is occupied based on the passive entry signal, and generates a control signal operative to halt transmission of the tire pressure signals when the vehicle is unoccupied.
