Automatic adaptation of brake boost to different braking loads

A method for operating an electromechanical brake booster. A pedal force is ascertained, a brake pressure is ascertained from the pedal force by an actuator, and the brake pressure applied to frictional brakes is set, thereby producing a vehicle deceleration. The actuator has a standard configuration wherein, in response to the pedal force, a brake pressure is ascertained that produces a specified standard deceleration of the motor vehicle if a specified disturbance variable has a specified standard value. The influence of the disturbance variable on the vehicle deceleration is compensated. The actuator has at least one control parameter for setting a compensation configuration, an actual value of the disturbance variable is detected, and the compensation configuration is set based on the respective difference between the ascertained actual value and the standard value.
