17 Claims

1. A computer for a motor vehicle, said vehicle comprising a plurality of wheels enabling the vehicle to move on a road, at least one of said wheels comprising a wheel sensor for measuring at least one value of a “pitch” parameter of the wheel, enabling the computer to determine a “pitch” coordinate of said wheel sensor along a predetermined “pitch” axis of the wheel orthogonal to a direction of movement of the vehicle and parallel to the plane of the road, relative to a predetermined reference of said pitch axis of the wheel, the computer being capable of:

a) receiving from the wheel sensor at least one value of the at least one pitch parameter of the wheel,

b) determining at least one pitch coordinate of the wheel sensor relative to the predetermined reference of the pitch axis of the wheel on the basis of the at least one value received,

c) detecting a geometric anomaly in the wheel including said wheel sensor when at least one determined pitch coordinate is outside a first predetermined range of values of coordinates on the pitch axis, centered on the predetermined reference of said pitch axis of the wheel between a minimum and a maximum, and

d) warning the driver of the vehicle, by sending a warning message, when an anomaly in the wheel has been detected.
