Abstract
A method for determining the absolute angular position of a steering wheel of an electric power-assisted steering column of a motor vehicle, including a means for measuring a dynamic parameter while the vehicle is running and including among others, the steps of periodically determining a multi-turn relative angular position, determining at least one dynamic parameter relating to the running conditions of the vehicle using the means for measuring said parameter, determining an absolute steering-wheel angle calculated according to at least one dynamic parameter, and weighting the calculated value of the absolute steering-wheel angle according to a test of the validity of the calculated value of the absolute steering-wheel angle and the origin of said value, in other words, the measurement means used to determine said at least one dynamic parameter.
