Abstract
The present invention concerns a method for determining the position of a movable steering member () belonging to a steering mechanism () of a vehicle that comprises at least a first movable member (), such as a shaft () of an assistance motor (M), and a second movable member (), such as a rack (), which cooperate with each other by means of at least one first link (L), said method comprising a step (a) that involves measuring the position (θ) of the first member (), then a step (b) that involves calculating the instantaneous position (θ) of the second member () from said position of the first member (θ), and a correction step (d) during which the calculation of the position (θ) of the second member () is adapted, taking into consideration the offset (δθυ) in the position of the second member () that results from the elastic deformation of the first link (L) under the force (C) transmitted by the latter.
