摘要： A method for operating an electromechanical brake device transmits the rotational motion of the electric brake motor to the brake piston by way of an axially movable transmitting element. In the instance that the brake piston lies at a distance relative to an associated brake pad, a hydraulic brake pressure is produced in a hydraulic vehicle brake.

摘要： A method for operating a hydraulic brake system of a motor vehicle includes enabling a parking brake function by actuating a pressure generator and an actuator such that the pressure generator and the actuator together generate a total clamping force at a wheel brake, and actuating the pressure generator based on a movement of an actuator element and/or a brake piston, the movement generated by the actuator. The brake system includes the wheel brake having the brake piston, a brake pedal device, the pressure generator configured to actuate the wheel brake, the actuator assigned to the wheel brake and having the actuator element configured to actuate the wheel brake. A force that displaces the brake piston in order to actuate the wheel brake is generated by the pressure generator and/or the actuator.

摘要： A method for operating a hill hold controller of a motor vehicle including at least one parking brake. The parking brake is disengaged according to an actuation of a gas pedal of the motor vehicle. The disengagement of the parking brake is released according to a variable representing a road gradient. The release to disengage the parking brake is granted, independently of the variable and/or the availability of the variable, when the gas pedal of the motor vehicle reaches or exceeds a predefinable release position by way of the actuation thereof.

摘要： A method for maintaining a brake system in a vehicle with a hydraulic vehicle brake and an electromechanical brake device with an electric brake motor includes preparing the brake system for maintenance operations by actuating the electric brake motor to displace a transmission member into a retracted position that is remote from a brake starting position in which a brake lining is located adjacent to a brake disk of the wheel brake device. The method further includes actuating the electric brake motor to displace the transmission member in the direction of the brake starting position after completion of the maintenance operations.

摘要： A method for releasing a first electric motor-actuated brake device for a vehicle includes actuating a second brake device for the vehicle in a clamping direction with a first brake device in a clamped state in order to produce a predetermined clamping force on a brake piston that is associated with the first brake device and the second brake device in common. The method further includes actuating the first brake device in a release direction before the second brake device reaches the predetermined clamping force.

摘要： A method for operating a hydraulic braking system of a motor vehicle includes generating a force for displacing a brake piston of a wheel brake of the brake system via a pressure generator and an electromechanical actuator to actuate the wheel brake. The pressure generator and the actuator are controlled to collectively generate a total clamping force at the wheel brake in order to enable a parking brake function. During the enabling procedure, an operating current of the actuator is monitored to determine a functional capability of the braking system, and the pressure generator is controlled such that the hydraulic pressure is modulated for a predeterminable period of time to unload or to load the actuator. The operating current of the actuator during this time period in order to determine the functional capability of the braking system.

摘要： A method for determining a leakage in a hydraulic brake system in a vehicle includes evaluating a suspected leakage in the hydraulic brake system and taking into account an actuation of an automated hand brake during the evaluation of the suspected leakage. The hydraulic brake system has a hydraulic footbrake and the automated hand brake has an electromechanical actuator. The hydraulic footbrake and the automated hand brake are configured to act on the same brake piston.
