Method for the driver assistance of a road vehicle

Abstract:

A method for the driver assistance of a road vehicle; the assistance method comprises the steps of: determining an actual steering angle of the front wheels; determining a desired steering angle of the front wheels; and changing the servo-assistance torque applied by a servo-assistance device to a steering system based on the actual steering angle and on the desired steering angle, so that the servo-assistance torque that is applied when a steering wheel is rotated in a first direction to change the actual steering angle causing it to approach the desired steering angle is greater than the servo-assistance torque that is applied when the steering wheel is rotated in a second direction, which is opposite to the first direction, to change the actual steering angle causing it to distance itself from the desired steering angle.
