Abstract
A difference .delta..sub.2 -.delta..sub.1 is formed between the steering angle .delta..sub.2 actually measured and the steering angle .delta..sub.1 calculated from the vehicle transverse acceleration, vehicle speed, and a series of constants. This difference (.delta..sub.2 -.delta..sub.1) is used to displace the working point on the .mu.-slip curve in the direction of an increase of the lateral stability, i.e., toward smaller slip values. Response can be improved by making the displacement also dependent on the rate of change of this difference or the rate of change of the actual steering angle. Preferably no reaction is produced when the difference is below a threshold angle unless one of the rates exceeds a respective threshold.
