System and method for integrated tire pressure monitoring and passive entry
First Claim
1. 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.

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.
