Patent ID: 7392119

Claim:
A device for locating the position, on the right or on the left, of a wheel ( 2 ) of a vehicle ( 3 ), comprising: two magnetic sensors ( 4 , 5 ) having axes of maximum sensitivity (S 4 , S 5 ) lying in a plane that is intersecting to the axis of rotation (R) of the wheel ( 2 ) and which axes are offset from one another in the intersecting plane by a predetermined angle θ, the two magnetic sensors mounted on said wheel and configured to detect and provide, at terminals of each of the sensors, a signal representative of variations in values of a magnetic field, means ( 7 , 8 ) for measuring the signal at the terminals of each of the magnetic sensors ( 4 , 5 ), the measuring means being able to deliver two periodic signals phase-shifted from one another by an angular value equal to (+ or −) θ, each of the two periodic signals representative of the variations in the values of the magnetic field as detected by said magnetic sensors during a revolution of the wheel ( 2 ), and a calculation unit ( 9 ) programmed to determine, from the phase shift between the two periodic signals, the direction of rotation of the wheel ( 2 ) and, from this direction of rotation and from the direction of travel of the vehicle ( 3 ), to deduce the location, on the right or on the left side of the vehicle, of the wheel ( 2 ).
