In a method for determining the start and the end of an automatic braking process, an automatic braking process is triggered when the actuation speed of a brake pedal exceeds a threshold value. The triggering of the automatic braking process is optimized by changing the threshold value as a function of the driving state, e.g. the speed of the vehicle when the brake pedal is actuated and, independently thereof, the position of the brake pedal. In addition, various criteria are described for terminating the automatic braking process as a function of the actuation force of the brake pedal, of the speed of the vehicle and of the pedal travel.
