Patent ID: 8095333

Claim:
A location device configured to be carried by a tire and wheel assembly so as to locate a right or left position of the assembly in a vehicle, the device comprising: two magnetic sensors with axes of maximum sensitivity; a measurement circuit for measuring a signal across terminals of each of the magnetic sensors, the measurement circuit being able to deliver two periodic signals phase-shifted with respect one another and each periodic signal representative of variations in values of a magnetic field detected by a corresponding magnetic sensor during a revolution of the tire and wheel assembly; and a calculation processor programmed to determine, based on the phase shift between the two periodic signals, a direction of rotation of the tire and wheel assembly, and to deduce, from the direction of rotation and a direction of travel of the vehicle, a right or left location of the tire and wheel assembly, wherein the two magnetic sensors have the axes of maximum sensitivity oriented in parallel, and wherein the two magnetic sensors are configured to be placed on the tire and wheel assembly at respective azimuths, and wherein the two magnetic sensors are configured to be placed on the tire and wheel assembly such that the axes of maximum sensitivity are oriented parallel to a rotation axis of the tire and wheel assembly.
