Abstract
Abstract In a system for remote monitoring of tire pressure in a vehicle having front tires including a right tire and a left tire, and rear tires including a right tire and a left tire, a system and method are provided for automatically identifying tire location. A transmitters mounted in each tire transmits tire information signals conveying tire pressure data and associated tire rotation direction data. A vehicle mounted receiver has a location a first distance from the front tires and a second distance from the rear tires, the first distance being different from the second. A vehicle mounted controller in communication with the receiver determines whether pressure data is associated with a front tire or a rear tire based on the strength of the tire information signal, and whether pressure data is associated with a right tire or a left tire based on the associated rotation direction data.
