System and method for remote tire pressure monitoring with low frequency initiation
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, each monitor comprising a sensor for sensing tire pressure, a transmitter for transmitting a signal representative of the sensed tire pressure, a battery for providing power to the transmitter, and a receiver for receiving an initiation signal;
a plurality of initiators, each initiator for mounting on-board the vehicle for association with one of the plurality of tire monitors, each initiator for use in generating a low frequency initiation signal for receipt by an associated receiver, the initiation signal causing the associated transmitter to transmit a tire pressure signal;
a vehicle receiver for mounting on-board the vehicle for receiving the tire pressure signals transmitted by the transmitters; and
a controller for mounting on-board the vehicle, the controller to be provided in communication with the plurality of initiators and the receiver, the controller for activating each of the plurality of initiators in order to generate the low frequency initiation signal and for processing the tire pressure signals received by the receiver to convey tire pressure information to a user, the controller further for activating each initiator in order to generate a low frequency electromagnetic field for use in recharging the battery in the associated tire pressure monitor.

Abstract
A system for remote monitoring of vehicle tire pressure includes monitors mounted in the tires, each including a tire pressure sensor, a transmitter for transmitting a tire pressure signal, a battery for the transmitter, and a receiver for receiving an initiation signal. Initiators are mounted on-board the vehicle, each initiator associated with one of the tire monitors. Each initiator is for use in generating a low frequency initiation signal for receipt by a tire receiver to cause the transmitter to transmit a tire pressure signal. A vehicle mounted controller activates the initiators in order to generate the low frequency initiation signals, and processes the tire pressure signals to convey tire pressure information to a user. The controller further activates the initiators in order to generate a low frequency electromagnetic field for use in recharging the batteries in the tire monitors.
