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 (&#x3b8;) of the first member (), then a step (b) that involves calculating the instantaneous position (&#x3b8;) of the second member () from said position of the first member (&#x3b8;), and a correction step (d) during which the calculation of the position (&#x3b8;) of the second member () is adapted, taking into consideration the offset (&#x3b4;&#x3b8;&#x3c5;) 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.
