Abstract
A method for controlling a compressed air brake system of a vehicle includes outputting an analog driver brake pressure via a brake pressure control line during driver braking by operating a brake pedal, a switching device set in a driver braking position to a brake circuit with at least one ABS stop valve device, a brake line, and a wheel brake. The method additionally includes, in the presence of both driver braking and the external brake demand signal, measuring the driver brake pressure and determining a driver brake pressure value. Furthermore, the method includes forming a combined brake pressure value by adding or superimposing the driver brake pressure value and an external brake pressure value contained in the external brake demand signal, and switching the switching device into the functional position and controlling the combined brake pressure value from the system pressure by actuating the ABS stop valve device.
