Abstract
In a system for remote monitoring of vehicle tire pressure, a system and method for automatically identifying tire location. A tire pressure monitor mounted in each tire includes a sensor for sensing tire pressure, a transmitter for transmitting a signal representative of the sensed tire pressure, and a magnetic switch for actuating the transmitter. An electromagnets is mounted on the vehicle in proximity to each tire location and generates a magnetic field causing the magnetic switch to actuate the transmitter of the associated tire pressure monitor. A controller mounted on the vehicle is provided in communication with the electromagnets, processes the tire pressure signals from the transmitters, and conveys tire pressure and location information to a user. The controller energizes the electromagnets so that each received tire pressure signal is automatically associated with a specific tire location.
