Patent ID: 8638089

Claim:
A device to be carried by a wheel-tire assembly to locate whether the assembly is positioned on a right side or a left side of a vehicle, the device comprising: two magnetic sensors with axes of maximum sensitivity, the two magnetic sensors providing two periodic signals that are phase shifted relative to one another, and each signal representing variations in a magnitude of a magnetic field detected by a corresponding one of the two magnetic sensors during a revolution of the wheel-tire assembly; a filtering element designed to eliminate components of the two periodic signals having frequencies equal to or below a given frequency; and a processing unit programmed to determine, from a phase shift between the two periodic signals, a direction of rotation of the wheel-tire assembly, and to deduce, from the determined direction of rotation and from a direction of travel of the vehicle, whether the wheel-tire assembly is located on the right side or the left side of the vehicle, wherein the two magnetic sensors are positioned on the wheel-tire assembly at distinct azimuthal locations.
