Abstract:
1. 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,
