Active steering system operating method for motor vehicle, involves producing overlapping steering angle, and producing impact moment by steering force support device when steering wheel angle reaches steering wheel-maximum angle

摘要

The method involves producing an overlapping steering angle (Sigma-m) by an overlapping steering gear (4), where the angle is overlaid to a steering wheel angle (Sigma-l). The overlapping guidance angle is adjusted opposite to an increase of the steering wheel angle provided by a driver, and is partially compensated when the difference of a reference yaw rate and an actual yaw rate exceeds a predetermined activation threshold value. An impact moment is produced by a steering force support device (9) when the steering wheel angle reaches a steering wheel-maximum angle.
