Publication number: 20090138158Abstract: In a method for controlling a motor vehicle via driving dynamics, using an auxiliary steering system, including a power steering assistance unit, a superposed transmission, and a final control element to correct a driver-steering angle by applying an auxiliary steering angle, an overall steering angle is formed to modify the wheel-steering angle of steered wheels with the aid of the superposed transmission, and a control and regulation unit assigned to the final control element determines a setpoint for the auxiliary steering angle. When an understeering state is detected, the setpoint of the auxiliary steering angle is modified such that the lateral wheel force is kept within a range of a maximally achievable maximum value for the lateral wheel force, which is dependent upon environmental influences, for the duration of the understeering state.Type: ApplicationFiled: November 25, 2008Publication date: May 28, 2009Inventors: Roland GREUL, Joerg Strecker, Christopher Kreis
