Method for situation-adaptive changing of steering stiffness of motor car, involves parameterizing angle controller/steering angle rate controller for steering intervention such that criticality of situation is reflected in stiffness

摘要

The method involves parameterizing a subordinate steering angle controller/steering angle rate controller for realization of an automatic steering intervention such that criticality of a situation is reflected in steering stiffness. An adaptation is carried out by an estimated sensor safety, where the adaptation takes place by a driver for speed alternatives. Steering stiffness is asymmetrically determined such that a steering movement of a driver leads to an obstacle for higher stiffness than away from the obstacle.
