Auxiliary steering angle control device for motor vehicle

摘要

A computing unit (21) computes a desired value (dPSIM) for a movement variable e.g. yaw speed of the vehicle based on the detected vehicle condition. A yaw speed sensor (10) is provided for determining the actual value (dPSI) of the movement variable and a computing unit (23) determines an auxiliary steering angle engagement (delta F/B) corresp. to the deviation between the desired and actual value of the variable. A detection unit (24) determines a roadway condition variable (R) for denoting the condition of roadway travelled over. A unit corrects the auxiliary steering angle regulating engagement namely reducing this, if the detecting unit (24) gives a signal, which indicates the poor condition of the roadway, being travelled over.
