Abstract
A method for estimating the absolute angular position of a steering wheel equipping a power-steering device, referred to as 'relative steering wheel position', of the shaft of a power-steering motor is assessed, a first estimation (Angle) of the absolute angular position of the steering wheel is assessed from at least one first model using the speed difference between the left and right rear wheels, a first dynamic offset equal to the difference between the first estimation (Angle) of the absolute angular position of the steering wheel and the relative steering wheel position is estimated, and the absolute angular position of the steering wheel is calculated by adding to the relative steering wheel position a total compensation offset determined from the first dynamic offset, also when restarting the vehicle, a switching-off offset corresponds to the value of the total compensation offset at the time when the vehicle was previously switched off.
