Abstract:
1. Hydraulic brake system for a land vehicle comprising: a control unit with inputs to receive input parameters, which indicate operational states of the land vehicle, and outputs to output control signals for the brake system, at least one wheel brake, at least one hydraulic fluid storage device to store hydraulic fluid, a controllable pump for controlled feeding of hydraulic fluid out of the hydraulic fluid reservoir to the at least one wheel brake, and a valve arrangement with a first operational state, in which a hydraulic connection to feed braking pressure which a driver generates to the at least one wheel brake is open, and a second operational state, in which the hydraulic connection is blocked, the brake system having a predetermined holding capacity for hydraulic fluid within the brake system and the control unit being set up to determine a current holding capacity for hydraulic fluid from the input parameters, and if the current holding capacity is increased compared with the predetermined holding capacity, to provide control signals for the valve arrangement, to bring the valve arrangement into the second operational state, and to provide control signals for the pump, to feed a quantity of hydraulic fluid corresponding at least to the capacity increase to the at least one wheel brake.
