摘要： To avoid an exceedance of a permissible maximum pressure in a hydraulic vehicle power braking system including anti-slip regulation, continuous valves are to be utilized as inlet valves of wheel brakes of the vehicle braking system, and the inlet valve of a wheel brake, whose outlet valve will be opened or is open in order to regulate the wheel brake pressure, is to be partially closed, so that this inlet valve acts as a throttle and limits a brake pressure in the vehicle braking system.

摘要： An electronically slip-controllable power braking system for a motor vehicle, in which a controllably drivable pressure generator supplies multiple brake circuits connected in parallel to one another with pressure medium under brake pressure. Each of the brake circuits are separable through existing first control valves from the pressure generator and include second control valves that are connected downstream from the first control valves to control the brake pressure in the wheel brakes, which are connected with the brake circuits. An electronic control unit in the brake circuits has three devices, the third device puts the first control valve of a brake circuit into a passage position if a leakage is established downstream from the second control valve in this brake circuit and if it is established that the pressure generated by the pressure generator has at least approximately reached or exceeded a pressure limit of the first control valve.

摘要： In a method for actuating a hydraulic braking system, a hydraulic fluid is temporarily stored in a storage chamber when the antilocking system is activated and recirculated back into the brake circuit with the aid of a recirculation pump. The target pump speed of the recirculation pump depends on the degree of filling of the storage chamber with hydraulic fluid and in addition on the control frequency of the antilocking system.
