Method for operating a motor vehicle in the event of a functional restriction of the motor vehicle, control unit for carrying out the method and motor vehicle with such a control unit

摘要

A method for operating a motor vehicle (1), comprising the steps of: - checking while the motor vehicle (1) is driving, ▪ whether there is a functional restriction on a brake system and / or a front-wheel steering of the motor vehicle (1); and / or▪ whether a collision of the motor vehicle (1) has been detected; - If the functional restriction and / or the collision is determined, at least one rear wheel steering angle is determined as a function of sensor data of the motor vehicle (1) and a predetermined driving behavior of the motor vehicle (1) determined, the sensor data being provided by a sensor unit (14); - actuation of a rear wheel steering (7) of the motor vehicle (1) according to the determined rear wheel steering angle in order to achieve the specified driving behavior, the driving behavior being specified in such a way that a skidding movement of the motor vehicle (1 ) is prevented or terminated, with sensor data relating to the yaw rate or the lateral acceleration of the motor vehicle (1) being provided by the sensor unit in order to determine the skidding movement of the motor vehicle (1).
