摘要
The present invention relates to a method of estimating a force rods (Fb), which is exerted, in a power steering system (1) fitted to a vehicle (2), on a steering rod (3) belonging to a steering mechanism (4) which connects an actuator, such as a steering wheel (5) or an assist motor (6), to a steerable steering wheel (7) carrying a tire ( 8) whose tread (8BR) is in contact with a ground (9), the value of the estimated linkage force (Fb) being corrected according to the longitudinal velocity of the vehicle (V_vehic), by means of a force component (F2) modeling the release of the elastic torsion of the tire (8), so as to reduce, in absolute value, the estimated linkage force (Fb), as a function of the longitudinal speed of the vehicle ( V_vehic), when the vehicle passes from a parking situation, in which the longitudinal speed of the vehicle (V_v ehic) is zero, at a rolling situation, in which the longitudinal velocity of the vehicle (V_vehic) is non-zero.
