Control device and method for operating an electromechanical brake booster of a brake system of a vehicle

A brake system for a vehicle comprising:

• an electromechanical brake booster;
• and
• a control device configured to operate the at least one electromechanical brake booster the control device having an electronic device configured to:
• specify a target rotational speed of a motor of the at least one electromechanical brake booster based on at least one brake-specifying signal that is output to the electronic device in relation to at least one of (i) a braking request of a driver of the vehicle and (ii) an automatic speed-controlling system of the vehicle;
• output at least one control signal to the motor of the at least one electromechanical brake booster based on the target rotational speed at;
• and
• specify a maximum target rotational speed of the motor of the at least one electromechanical brake booster based on at least one prevailing current strength of a motor current of the motor of the at least one electromechanical brake booster and a prevailing rotation angle of a rotor of the motor of the at least one electromechanical brake booster,
• wherein the target rotational speed of the motor of the at least one electromechanical brake booster is specified less than or equal to the maximum target rotational speed.
