ABSTRACT:
A method of determining a set value of the assisting force in a power steering system reduces the assisting force in the power steering system as a function of the steering angular velocity (LWG). An estimate of the general driving situation with respect to the cornering force taking place by a variable representing a set value (a.sub.yset) of the lateral acceleration is derived from the steering angle (LW), by determining a variable representing the lateral acceleration (a.sub.y) and by deriving a critical driving state from a deviation of the variable representing the lateral acceleration (a.sub.y) from the variable representing the set value (a.sub.yset) of the lateral acceleration above a threshold value. The reduction of the assisting force in the power steering system as a function of the steering angular velocity LWG takes place only as long as the critical driving state is detected.
