Abstract
The system for determining the absolute angular position θ of a steering wheel () of a motor vehicle with respect to the chassis thereof comprises a device for incrementally measuring the relative angular position δ of the steering wheel, a device () for measuring the differential velocity ΔV/V of the wheels mounted on the same axle and a processing device () for sampling the angular positions and differential velocities at a period t. Said device comprises computing means suitable to determine at moments tn: the estimate θ*(t) of an absolute angular position θ(t) according to the differential velocity ΔV/V, the mean difference offset(t) between the angular positions θ*(t) and δ(t), wherein i is a variant ranging from 0 to n and the absolute angular position θ(t) by the addition between the mean difference offset(t) and the angular position δ(t).
