Abstract
A method and system for ensuring reliable operation of a brake booster system for a vehicle braking system in which a pressure value prevailing in the brake pressure reservoir of the brake booster system is sensed by a pressure sensor. An error occurring in the brake booster system is detected by evaluating the sensed pressure value prevailing in the brake pressure reservoir as a function of the actuation of the brake actuating mechanism. The brake booster system includes a diagnostic circuit that is connected to the pressure sensor and to the brake actuating mechanism.
