    • 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.
    • 确定动力转向系统中辅助力的设定值的方法根据转向角速度(LWG)减小动力转向系统中的辅助力。 通过确定表示横向加速度(ay)的变量,通过由转向角(LW)导出表示横向加速度的设定值(ayset)的变量而发生的相对于转弯力的一般驾驶状况的估计, 并且从表示横向加速度(ay)的变量的偏差与表示横向加速度的设定值(ayset)的偏差导致临界驱动状态高于阈值。 作为转向角速度LWG的函数,动力转向系统中的辅助力的减小仅在检测到临界驱动状态时才发生。
