Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method for operating a braking mechanism includes controlling an actuator comprising an electric motor in such a way as to move an actuator element into a predefined position. Upon completion of the controlling action on the actuator, at least one motor coasting variable is measured. On the basis of the measured motor coasting variable, it is verified whether the actuator element has moved into the predefined position.

Abstract: A braking system for automatic driver-independent deceleration of a vehicle includes a hydraulic vehicle brake and a backup braking system. The hydraulic vehicle brake includes an adjustable brake pressure control device. A method for automatic driver-independent deceleration of a vehicle includes decelerating the vehicle by actuating a braking pressure control device and, in response to a set point valve set in a hydraulic vehicle brake exceeding a threshold value, actuating a backup braking system.

Abstract: 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.

Abstract: 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.

Abstract: A vehicle steering system includes (i) a first control unit configured to perform the steering function of the vehicle, (ii) a status detection unit configured to detect the operational state of the first control unit, and (iii) at least one second control unit configured to participate in the control of the steering function of the vehicle in the event that an abnormal operational state of the first control unit is detected. A method and a computer program product for controlling vehicle steering is also disclosed. Not only can redundancy for the steering system be provided to high-level autonomous driving systems and/or assisted driving system, especially achieving redundant design for steer-by-wire systems and ensuring safety when the vehicle is in motion, but it can also effectively enhance the stability and comfort of vehicle steering.

Abstract: 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.
