Abstract: A method is aimed at controlling a steer-by-wire steering system of a vehicle having at least one steering axle having at least two steer wheels electronically controlled by a control member. In the case of asymmetric adhesion conditions, the method anticipates steering into the skid for the first steer wheel that is on the surface exhibiting the higher coefficient of adhesion—for example asphalt—so as to counter a moment applied to the Z-axis. At the same time, the second steer wheel which is on the surface having the lower coefficient of adhesion—for example a sheet of black ice—remains in the vehicle direction of travel or is oriented towards the second steer wheel in a snow plough mode. The vehicle stability is vastly improved when the vehicle regains an area of uniform adhesion.

Abstract: The invention relates to a method for determining a set steering angle β0 of steered wheels of a vehicle comprising a tractor and a trailer that is articulated with regard to the tractor. This method makes it possible to produce a set value that can be used for various purposes. This set value can thus be used for controlling an actuator acting upon the steering angle or for being communicated in order to inform the driver. According to the invention, during reversing maneuvers: based on a target point C via which the driver would like the path of the vehicle to pass, an angle set value ?c between the axes of the trailer and of the tractor is determined according to said target point C and to the dimensions of the vehicle, and; the set steering angle β of the steered wheels is determined according to a servo-system causing the measured angle ? between the axis of the trailer and the tractor to tend toward said angle set value ?c.
