Abstract

In a selected operating situation, the automatic control circuit, which is closed during normal operation, is opened, the final control element of the wheel brake being actuated within the scope of an open-loop control process. The drive signal value for the wheel brake changes in accordance with a predetermined time function, and the application pressure or release pressure is found on the basis of the characteristic behavior of a value representing the braking action.
