ABSTRACT:
In an electronically controllable braking system for motor vehicles with a brake pressure generator unit which comprises a master cylinder for generating a brake pressure, a brake pedal via which an actuation force can be introduced into the brake pressure generator unit for actuating the brake pressure generator unit, an electronically controllable brake booster, either for amplifying the actuation force introduced via the brake pedal for the actuation of the brake pressure generator unit, or for effecting an actuation of the brake pressure generator unit, as well as sensors which sense the brake pressure generated by the brake pressure generator unit and a parameter for an electronic control unit, which is related to the amplification of the electronically controllable brake pressure booster, there is provided, in order to comply with a very high safety standard at relatively low cost expenditures, that the electronic control unit determines the actuation force which is introduced via the brake pedal from the brake pressure generated by the brake pressure generator unit and the parameter which is related to the amplification of the electronically controllable brake booster. This results in the advantage that the actuation force which is introduced via the brake pedal can be determined reliably and safely without necessitating the employment of a force sensor.
