OPERATIONAL METHOD FOR CONTROLLING THE BRAKE PRESSURE GENERATOR OF THE MAIN SYSTEM

An operational method for controlling a first brake pressure generator. The operational method includes reading the detected wheel speeds into the brake pressure generator control unit, simulating a control strategy of the secondary control unit for controlling the hydraulic unit based on the wheel speeds so that a brake pressure required at the respective wheel is ascertained, predicting the pressure resulting from the control strategy of the secondary control unit and the brake pressure at the first brake pressure generator, and controlling the first brake pressure generator in accordance with the predicted resulting pressure if the predicted resulting pressure exceeds a limit value, so that the pressure resulting at the brake pressure generator is lower than the predicted pressure due to an activation of the first brake pressure generator.
