Abstract

The invention relates to a driver assistance method for a motor vehicle that is moving in a roadway, during which, on the basis of a data item (yL) relating to the position of the motor vehicle relative to the roadway, the position of the motor vehicle is taken into account The torque applied by the driver to this steering member (T A ) to determine (c) the corrective torque to be applied to the steering member of the motor vehicle (T C ), so that the motor vehicle follows the target path. According to the invention, this method further comprises the following steps, during which steps: d) determining a filtered correction torque (T CF ) such that the value of the filtered corrective torque is systematically smaller than the value of the corrective torque when the applied torque is substantially opposite to the corrective torque, and e) the filtered A corrective torque is applied to a steering member of the motor vehicle.

Description

technical field [0001] The invention generally relates to the field of driver assistance methods for motor vehicles. [0002] More specifically, the invention relates to a driver assistance method for a motor vehicle using a roadway, the method comprising the steps of: [0003] a) obtaining at least one data item relating to the position of the motor vehicle relative to the traffic lane), [0004] b) obtaining the torque applied by the driver of the motor vehicle to the steering member of the motor vehicle, [0005] c) Determining a corrective torque to be applied to said steering member depending on said data items, taking into account said applied torque, such that the motor vehicle follows a target path. Background technique [0006] Today, many motor vehicles are equipped with driver assistance systems which make it possible to apply an additional torque to the steering column of the vehicle by means of an electric motor in order to assist the driver of the vehicle in ...
