Abstract:
A method for operating a dual-circuit hydraulic brake system of a vehicle having an ABS function to feed back pressure medium from low-pressure reservoirs. When there is an autonomous pressure buildup request to increase brake pressure and an ABS control system is simultaneously activated, the following steps are carried out: monitoring the filling degree of the low-pressure reservoirs; emptying the low-pressure reservoir whose filling first reaches a defined threshold value; and if, during the execution of the low-pressure reservoir emptying process at the one low-pressure reservoir, the filling of the other low-pressure reservoir reaches the threshold value and the degree of emptying of the one low-pressure reservoir undershoots a defined threshold value, or the filling of the other low-pressure reservoir exceeds the threshold value by k/100, interrupting the low-pressure reservoir emptying process at the one low-pressure reservoir, and carrying out a low-pressure reservoir emptying process at the other low-pressure reservoir.
