System and method for automatic location assignment of wheels equipped with pressure sensors

Abstract

A method of operating a tire pressure monitor system (12) on a vehicle (10) to determine a wheel location of wheels (14) equipped with pressure sensors (16). The method includes equipping a plurality of wheels (14) with a pressure sensor (16), determining a plurality of pressure values from each pressure sensor (16), detecting a variation of the pressure values from a plurality of pressure sensors (16), and determining a wheel location based on a comparison of the variations of the pressure values. Variations useful for determining wheel location may include running over an object such as a rumble strip or pot-hole on the roadway, or the vehicle (10) executing a turn.

Description

technical field [0001] The present invention relates generally to tire pressure monitoring systems, and more particularly to determining the wheel position of pressure sensor-equipped wheels based on a comparison of changes in pressure values ​​that occur while the vehicle is being operated. Background technique [0002] Some vehicles are equipped with tire pressure monitoring systems. These systems generally indicate the tire pressure of the wheels at a particular wheel alignment or wheel position. For example, the system individually indicates tire pressure at front right (RF), rear right (RR), front left (LF) and rear left (LR) wheel positions. Some systems require reprogramming of the wheel position by a service technician or the vehicle owner if the position of the wheel changes. Various approaches have been proposed for the system to automatically recognize or self-train wheel positions, some of which require an undesired addition of expensive hardware. For various ...
