Patent ID: 7750623

Claim:
A method of locating the right or left position of a wheel ( 2 ) of a vehicle ( 3 ) equipped with an electronic monitoring system unit ( 1 ), characterized in that it consists: in incorporating in the electronic unit ( 1 ) a magnetic measuring component ( 4 ) comprising a core ( 5 ) made of ferromagnetic material on which are arranged, crosswise, two windings ( 8 , 9 ) configured to present maximum sensitivity axes (S 8 , S 9 ) offset from each other by a predetermined angle θ, and in positioning said magnetic measuring component in said electronic unit so that the maximum sensitivity axes (S 8 , S 9 ) of the windings ( 8 , 9 ) extend in a plane intersecting the axis of rotation (R) of the wheel ( 2 ), and, when the vehicle moves in a given direction of movement: in measuring a signal generated by the variation of a magnetic field at the terminals of each of the windings ( 8 , 9 ), so as to deliver two periodic signals phase-shifted from each other by an angular value equal to (+ or −) θ, each representative of the variations of the values of the magnetic field detected by said windings during a wheel rotation ( 2 ), in determining from this phase shift the direction of rotation of the wheel ( 2 ), and in deducing, from this direction of rotation and from the direction of movement of the vehicle ( 3 ), the location of the right or left position of the wheel ( 2 ).
