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.
