  • Patent number: 11572048
    Abstract: The disclosure relates to a control device and a corresponding method for operating an electromechanical brake booster of a brake system of a vehicle, comprising an electronics unit that defines a target variable with respect to a target rotational speed of a motor of the electromechanical brake booster, taking into account a brake input signal with respect to a braking request, and that sends at least one control signal to the motor. The electronics unit defines a maximum target variable with respect to a maximum target rotational speed of the motor, taking into account a current intensity of a motor current of the motor and a current angle of rotation of a rotor of the motor, and defines the target variable with respect to the target rotational speed of the motor of the electromechanical brake booster to be at the most equal to the defined maximum target variable.

  • Patent number: 11273816
    Abstract: In a method, which can be performed by a control device for carrying out an emergency braking and/or panic braking of a vehicle, in a first phase, a setpoint vehicle deceleration requested instantaneously by a driver is ignored and a motor of an electromechanical brake booster is operated in a predefined high power mode such that a main brake cylinder pressure in the main brake cylinder is increased; in an intermediate phase, the main brake cylinder pressure is reduced to a setpoint pressure by pumping brake fluid from the main brake cylinder into the at least one wheel brake cylinder and the motor force of the motor is reduced to a setpoint force; and the brake pressure increase in the at least one wheel brake cylinder is continued during a second phase only if the driver requests instantaneously a setpoint vehicle deceleration.
