Abstract: A method for operating a motor vehicle having two wheels, each of which is associated with a parking brake. The parking brakes are controlled as a function of a friction between the respective wheel and the ground.

Abstract: A method for operating a braking system for a motor vehicle, including a service brake unit and the service brake unit is activated to generate a brake force on a wheel axle of the motor vehicle at least temporarily as a function of a setting of an operating element. The generation of the brake force is performed using a calibration data set stored in a control unit of the braking system. An identifier stored in the operating element is transmitted to the control unit and used for a compatibility check. If the compatibility check is successful, a configuration of the operating element takes place and a generic data set stored in the control unit is used as the calibration data set and an operating element-specific data set stored in the operating element is transmitted to the control unit and used as a calibration data set after the transmission.

Abstract: A braking system of a vehicle, with at least one brake control system with a brake pressure regulator which, in case of a braking request, builds up a hydraulic brake pressure by which the vehicle wheel brakes can be actuated. The brake control system is attached to the vehicle body via a holder. For the detection of a holder failure, an evaluation unit is provided, which acquires a sensor signal curve from an internal sensor built into the brake control system. In the evaluation unit, a signal comparison occurs. The acquired sensor signal curve is compared to a reference signal curve. In case of a significant deviation of the acquired sensor signal curve from the reference signal curve, the evaluation unit generates a holder damage signal.

Abstract: A method for engaging a parking lock of a motor vehicle having a service brake and a parking brake, in which the parking lock is engaged, while by means of a braking device of the motor vehicle, the rolling away of the motor vehicle is at least restricted, wherein as the braking device, an additionally provided braking device of the motor vehicle, different from the service brake and from the parking brake, is used.

Abstract: A parking brake system for a vehicle, in particular for a motor vehicle, includes two control units, by means of which two actuators, which are designed to actuate respective wheel brakes, can be controlled. The control units are connected to a power source via separate lines, wherein exclusively one of the control units is connected to an operating device which is designed to transmit signals to the control unit for actuation of the wheel brakes. The control unit is designed to control at least one of the actuators, dependent on the signals for actuation of the wheel brakes.

Abstract: A method for activating a braking device in the drive train of a vehicle with an automatic gear box, a gear-side parking brake, and a braking system. The vehicle, starting from a parked position with an engaged parking lock, and under the presence of a starting condition, a control apparatus independent from a driver request, controls the braking system to secure against the vehicle rolling away by until the parking lock is released.
