Abstract

A method for controlling the movement of a vehicle in an automatic driving operation involves, during the automatic driving operation, the vehicle capable of being operated both in a regular operating mode and in an emergency operating mode. When a functional impairment of the regular operating mode is established, a switch from the regular operating mode to the emergency operating mode is carried out. In the emergency operating mode, the vehicle is guided automatically to an emergency stop position. In the emergency operating mode, the vehicle is braked with a deceleration profile which contains three deceleration phases, namely a first deceleration phase with a momentary strong braking, a second deceleration phase with a somewhat longer moderate braking, and a third deceleration phase with a strong braking lasting until the vehicle has come to a standstill or until the vehicle driver of the vehicle takes over a vehicle guidance of the vehicle.
