Drive assisting method for reversal path with drawn vehicle
First Claim
1. A method for assisting with backing-up maneuvers of a vehicle comprising a tractor and a trailer that is articulated with respect to said tractor, said vehicle being equipped with a steering assist device in which a steering angle of steered wheels of said vehicle is displayed on a display device as a position within a displayed range of steering angle positions within which said steering angle should be maintained, the method comprising:
- in response to selection of a target point (C) through which a path of the vehicle is to pass during said backing-up maneuvers, calculating a steering angle setpoint value (β
0) as a function of said target point (C) and of a geometry of the tractor and trailer of the vehicle; and
displaying said steering angle setpoint value (β
0) on said display device accessible to the driver of the vehicle, in comparison with said display of an actual steering angle value (β
) that corresponds to the position of the steered wheels with respect to a central axis of the vehicle.

Abstract
The invention relates to a drive assisting method for the reversal path of a vehicle which consists of a tow track and a trailer pivotable with respect thereto and is provided with a conventional mechanical steering device. The inventive method consists in selecting a target point (C), which the vehicle path should pass through, Determination in calculating the steering angle instruction β0 according to said target point (C) and the vehicle geometry and in displaying said steering angle instruction β0 in comparison with an actual steering angle β, which corresponds to the position of the member (21) of the steering device, on a display device accessible to a driver.
