Method for boosting the braking force in an electronically slip-controllable vehicle brake system having electromechanical brake boosting

A method for boosting a braking force in an electronically slip-controllable vehicle brake system having electromechanical brake boosting,

• providing a communications link between a first electronic control device of a brake booster and a second electronic control device of a brake-pressure control device, wherein the vehicle brake system includes a braking-intention detection device to which an actuation travel correlating with the applied braking force is allocatable, the brake booster which drivable by the first electronic control device to execute an actuation stroke as a function of the actuation travel of the braking-intention detection device, a travel sensor system which outputs a travel signal that correlates with the actuation travel of the braking-intention detection device, and the brake-pressure control device having the second electronic control device and a drivable pressure generator;
• checking, for an existing disturbance in the brake boosting, whether the travel sensor system, the first electronic control device of the brake booster, and the communications link between the control devices are functional;
• and
• generating, via the first electronic control device, if the devices are functional, a trigger signal as a function of a travel signal from the travel sensor system, and transmitting the trigger signal via the communications link to the second electronic control device.
