ABSTRACT:
The method consists in measuring the speed, VV, of the vehicle, in comparing the current speed, VV, to a predetermined speed, VM, in order to zero a shaft turn counter when, VV, is greater than, VM. VM, is updated to the value, VV, when, VV, is greater than, VM. The direction of movement of a steering shaft in the vehicle into a position corresponding to an extreme of the signal emitted by an angular position sensor coupled to the shaft and sensitive to the angular position of the shaft during one turn is detected, in order to increment or decrement the counter according to the direction detected. The number of turns recorded is combined with the current signal, VS, emitted by the sensor in order to form a signal representing the angle of rotation of the steering shaft, during several turns. The implementation of the method is a device for controlling, for example, an adaptable suspension for a motor vehicle.
