System for remote tire pressure monitoring with low frequency initiation antenna

摘要

A system for remote monitoring of tire pressure in a vehicle having multiple tires, where each tire has an associated wheel well. The system includes a tire monitor mounted in one of the tires that includes a transmitter for transmitting a signal representative of a sensed tire pressure, and a receiver for receiving an initiation signal. An initiator mounted on-board the vehicle associated with the tire is for use in generating a low frequency initiation signal for receipt by the receiver to cause the transmitter to transmit a tire pressure signal. An antenna in communication with the initiator transmits the low frequency initiation signal. The antenna includes a multi-turn loop on a surface of the wheel well associated with the tire such that the low frequency initiation signal transmitted by the antenna is received by the receiver for any tire position.
