Abstract: A method for operating an electromechanical brake booster of a brake system of a vehicle. A virtual dynamic brake pressure value representing a driver braking request of a driver of the vehicle is determined in a control unit of the brake booster using a pedal travel of a brake pedal of the vehicle acquired at the brake booster, a clearance value of the brake system read in via a data bus of the vehicle from a brake control unit of the brake system, and a stiffness factor of the brake system read in via the data bus from the brake control unit.

Abstract: A method for operating a brake system of a vehicle. The brake system having: a first and a second actuator for generating a hydraulic pressure in the brake system; a first control device designed to control the first actuator; and a second control device designed to control the second actuator. In the method, the brake system is monitored for emergency braking, wherein the first actuator is controlled by the first control device to generate a first hydraulic pressure for achieving a pre-specified emergency deceleration of the vehicle if emergency braking is detected. The second control device is controlled by the first control device to control the second actuator to generate a second hydraulic pressure when the deceleration that can be or is achieved by means of the first actuator is less than the pre-specified emergency deceleration.

Abstract: A control apparatus for an electromechanical-brake-booster of a vehicle, having: an electronic-device to control an electric-motor of the electromechanical-brake-booster so that an output piston, connected indirectly to the electric-motor, of the electromechanical-brake-booster is displaceable out of its initial-position by the controlled electric-motor, such that only after a displacement of the output-piston out of its initial-position by at least a predefined limit displacement travel does a frictional engagement exist between the output-piston and an input-piston that is indirectly connected to the brake-pedal and is displaced by the actuation of the brake-pedal, and such that a speed of the output-piston displaced out of its initial-position by less than the limit displacement travel is at first increased from a reference-speed to a maximum-speed and is then reduced from the maximum-speed to the reference-speed.
