A braking device for a motor vehicle includes at least one brake, at least one brake pad, a brake disk, and an elastic element. The elastic element is configured to place the brake pad against the brake disk such that the brake pad and the brake disk generate either no braking force or a small braking force acting on the motor vehicle. The at least one brake is operatively interrelated with the elastic element.

Braking device for a motor vehicle, and method for controlling the braking device

A parking brake for a vehicle includes an electric brake motor, a transmission, and a brake piston. The transmission transfers a drive movement of the motor to the brake piston. The transmission has a transmission efficiency that steadily increases as a temperature in the transmission rises.

Parking brake in a vehicle

The disclosure relates to a brake system of a motor vehicle having at least one parking brake which can be activated, having a plurality of means for operating the parking brake and having at least one control device which has at least one of the means, characterized in that at least one further control device has at least another of the means.

Brake system, method for operating same

In a method for setting a parking brake that has an electromechanical brake device having an electrical brake motor, the release time duration for displacing the electrical brake motor in the release direction is determined from the closing time duration in which the brake motor was previously displaced in the closing direction.

Method for setting a parking brake in a vehicle

A method is used for operating a braking device of a vehicle, in particular a parking brake device. The braking device comprises an electromotive actuator that displaces an actuator element either into a clamping position for subjecting a brake disk to a clamping force or into a release position for releasing the brake disk. A brake disk temperature is determined in order to activate the actuator depending on the determined brake disk temperature. The brake disk temperature is determined depending on at least one actuator current value.

Method and apparatus for operating a braking device, braking device

A method for releasing a brake device for an automatic parking brake, a corresponding device, and a control device enable safely releasing the parking brake without stress on components. A method for actuating a parking brake with a brake device having a brake caliper housing with a chamber configured to receive a fluid, a brake piston, a spindle and a spindle nut, includes determining a first hydraulic driver-applied pre-pressure in the chamber during a mechanical application process of the parking brake. The method further includes comparing the first driver-applied pre-pressure to a predetermined pressure threshold value via the control device; and building up a hydraulic support pressure in the chamber in order to unload the spindle when the first driver-applied pre-pressure is above the pressure threshold value.

Method for actuating an automatic parking brake

In a method for setting the clamping force, which is exerted by a parking brake, a portion of which clamping force is at least partially generated by an electromechanical braking device having an electric actuator, and another portion is additionally generated by an additional braking device, as needed, the actual force curve is determined and compared to a characteristic, defined force curve to determine the magnitude of the electromechanical clamping force to be supplied by the electric actuator. If the actual force curve corresponds to the characteristic force curve, then, in addition to the electromechanical clamping force, an additional clamping force of the additional braking device is also taken into account for obtaining the setpoint clamping force.

Method for setting the clamping force exerted by a parking brake

A method and corresponding device for turning at least one steerable wheel of a motor vehicle during parking on a longitudinal inclination of a roadway includes activating a parking brake of the motor vehicle, ascertaining the inclination angle of the vehicle inclination that is effected by the longitudinal inclination of a roadway, and turning the steerable wheel to achieve a wheel angle as a function of at least one specifiable and/or ascertained parameter. The setting of the magnitude of the wheel angle takes place as a function of at least one surroundings situation of the motor vehicle, ascertained using at least one sensor. The corresponding device cooperates with a parking brake, an inclination angle sensor, a steering device, and a surroundings recording device having at least one sensor.

Method and device for parking a motor vehicle

In a method for setting the clamping force exerted by a parking brake, which is generated at least partially by an electromechanical braking device and, if needed, in supplementary fashion by a hydraulic braking device, in the provision of the hydraulic clamping force, a boost pressure to be generated in the hydraulic braking device is increased with respect to a switch-off pressure at the switch-off time that corresponds to the hydraulic clamping force.

A method for operating a parking brake with an electromotively driven parking brake mechanism includes applying the parking brake by the electric motor, switching off the electric motor in the state in which the parking brake is applied, switching on the electric motor after a prespecified time and reapplying the parking brake mechanism in the brake application direction. During the brake reapplication operation, an electrical variable of the electric motor is determined and compared with a reference value. The brake reapplication process is continued or terminated depending on whether the electrical variable, or a variable derived therefrom, is smaller or greater than the reference value.

Method for operating a parking brake having an electromotively driven parking brake mechanism

A method for operating a parking brake of a vehicle, in particular of a motor vehicle, which parking brake operates in the superposition mode, the brake force of the parking brake being applicable by two different force-generating actuators mutually supporting one another in the superposition mode. It is provided that the force-generating, in particular pressure-generating, actuator is activated for support even before the superposition.

Method for operating a parking brake of a vehicle

In a method for setting the clamping force applied by a parking brake, which is generated by an electromechanical brake device and additionally by a hydraulic brake device as needed, the hydraulic pressure is ascertained, and the pressure is assigned a pressure reference path which is compared with an actuator path.

Method for setting the actuating force applied by a parking brake

A method for operating a parking brake having an electromechanical braking device, which includes an electric brake motor, the electromechanical braking device being re-applied in order to generate a clamping force again in the case of a fault of the release process of the electromotive braking device.

In a method for reducing the clamping force applied by a parking brake, which may be generated at least partially by an electromechanical brake device having an electric brake motor and supplemented if necessary by a hydraulic brake device, a signal is generated for actuating the hydraulic brake device for the case that it is not possible for the brake motor to be released for reducing the clamping force.
