To securely park a motor vehicle (1), a parking brake (5) is often used, said brake actuating a hydraulically or electrically assisted braking system (5, 5a) by means of a control button (2). If a speed signal is not available, the reliable functioning of the parking brake (5) is no longer guaranteed. According to the invention, to activate the parking brake (5), the control button (2) is depressed for at least a predetermined time period, the displacement mode of the motor vehicle (1) is detected using the signal of an additional device (3,4, 6 to 9), e.g. the status of the brake pedal, the park position of the gearbox, an acceleration sensor, a positioning system, a driver assistance system or level information and the parking brake (5) is only activated if the motor vehicle (1) has attained a predetermined limit value for the displacement mode. |
