A method for providing a brake force in a vehicle with a hydraulic vehicle brake and an electromechanical brake device includes determining a position of a brake piston at a brake contact point on the basis of a state variable of an electric brake motor when the electromechanical brake device is released. The method further includes displacing the brake piston in a positioning operation until reaching a braking start point.

Method for operating an automated hand brake comprising at least one first actuator and one second actuator for a motor vehicle, wherein each of the actuators is activated for an operation using a defined amperage, is characterized in that, in a first phase, the actuators are operated essentially synchronously until a defined first amperage is reached and, in a subsequent phase, the actuators are sequentially operated until a defined second amperage is reached.

A control device and method for executing a holding function using a hydraulic braking system of a vehicle including building up an initial holding pressure in at least one wheel brake cylinder using at least one brake pressure buildup device and closing at least one shutoff valve situated between the at least one wheel brake cylinder and the at least one brake pressure buildup device, a new holding pressure being built up in the wheel brake cylinder, in that an intermediate pressure less than the new holding pressure is built up between the shutoff valve and the brake pressure buildup device using the brake pressure buildup device, the shutoff valve is opened upon the presence of the intermediate pressure between the shutoff valve and the brake pressure buildup device, and brake fluid is transferred using the brake pressure buildup device through the open shutoff valve into the wheel brake cylinder.

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.

The disclosure relates to a method for determining the actuation distance in an electromechanical brake device having an electric brake motor, wherein the distance of a spindle nut is first determined while taking into account an initial value for the motor constant and the motor total resistance and a correction of the spindle nut distance is then performed after an estimation has been performed.

In a method for controlling a parking brake in a vehicle, in order to set a clearance between the brake pad and the brake disk, a supply voltage is first applied to an electric motor, after which the supply voltage is switched off before the brake pad comes into contact with the brake disk.

A method for operating an automated parking brake in a motor vehicle, having a hydraulic actuator for producing a hydraulic force component and an electromechanical actuator for producing an electromechanical force component, includes superimposing the hydraulic force component and the electromechanical force component to obtain a total clamping force for a parking brake operation, and maintaining the total clamping force by self-locking of the parking brake. The method further comprises during the parking brake operation, setting at least one defined hydraulic pressure level using the hydraulic actuator, and locking-in a defined hydraulic pressure level with a valve when the at least one defined hydraulic pressure level is reached.

In the case of a method for performing a function check on an electromechanical brake device having at least one electric brake motor, the motor current is measured at the brake motor and compared with a calculated motor current, wherein an error signal is generated in the event of an inadmissibly high deviation.

An automated parking brake for a motor vehicle having at least one brake device is configured to adopt at least two states. In a first state, no clamping force is established by the parking brake, and in a second state, a clamping force is established by the parking brake. A transition point defines a transition between the two states. An identification of the transition point is carried out during a releasing process of the parking brake.
