Abstract:
A system for remote monitoring of tire pressure in a vehicle having a plurality of tires, the system comprising:a plurality of tire monitors, each monitor for mounting in one of the plurality of tires to monitor tire pressure, each monitor comprising a transponder for transmitting a signal representative of the tire pressure and for receiving a control signal for use in regulating transmission of the tire pressure signal; a receiver for mounting on-board the vehicle for receiving the tire pressure signals transmitted by the transponders and for receiving a passive entry signal transmitted by a remote passive entry device; a transmitter for mounting on-board the vehicle for transmitting to the transponders the control signal for use in regulating transmission of the tire pressure signals; and a controller for mounting on-board the vehicle and to be provided in communication with the receiver and the transmitter, the controller for conveying tire pressure information to a vehicle occupant based on the tire pressure signals, determining whether the vehicle is occupied based on the passive entry signal, and generating the control signal for use in regulating transmission of the tire pressure signals, wherein the control signal is operative to halt transmission of the tire pressure signals by the transponders when the vehicle is unoccupied.
