Method for determining a set steering angle of steered wheels of a vehicle
First Claim
1. A method of determining a steering setpoint angle (β
-
0) for the steered wheels of a vehicle (1) comprising a tractor (2) and a trailer (8) that is articulated with respect to the tractor (2) during backing-up maneuvers, in which;
a setpoint angle value (θ
C) is determined for the angle between the axes of the trailer (33) and of the tractor (38) using a target point (C) through which the path of the vehicle is to pass and as a function of said target point (C)the steering angle setpoint value (β
0) for the steered wheels is determined as the result of feedback control that causes the measured angle (θ
) between the axis of the trailer and of the tractor to tend toward said angle setpoint value (θ
C);
characterized in that the value of the setpoint angle (θ
C) between the axes of the trailer (33) and of the tractor (38) is determined as a function of the geometry of the vehicle.

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.
