The invention relates to a control device () for at least one electromechanical brake booster of a brake system of a vehicle having an electronics device () that is designed to compare a provided sensor signal () relating to a differential path (d) between a valve body (), displaced by a controlled motor, of the electromechanical brake booster and an input rod () of the brake system with a specified normal value range, such that, if the sensor signal () relating to the differential path (d) lies outside the specified normal value range, the electronics device () is in addition designed to define a maximum limit value for a target quantity relating to a target motor torque to be carried out by the motor, at least taking into account the sensor signal (), in such a way that, at least during a specified time interval after the defining of the maximum limit value, at most an actual motor torque corresponding to the defined maximum limit value can be carried out by the controlled motor. The present invention also relates to an electromechanical brake booster for a brake system of a vehicle, to a brake system for a vehicle, and to a method for operating an electromechanical brake booster of a brake system of a vehicle.

Control device and method for operating an electromechanical brake booster

A method for ascertaining information relating to a mechanically effective power of an active brake booster of a braking system of a vehicle, including: ascertaining a first piece of information relating to an assisting force that is effectuated with the aid of the operated active brake booster, ascertaining a second piece of information relating to a pressure force in a master brake cylinder of the braking system, situated downstream from the active brake booster, the pressure force acting counter to the operated active brake booster, ascertaining a third piece of information relating to a spring force of at least one spring of the active brake booster and/or of the braking system, the spring force acting counter to the operated active brake booster, and establishing the information relating to the mechanically effective power of the active brake booster, taking into consideration the first, second, and third pieces of information.
