The invention relates to a hydraulic braking system (1) for a vehicle, comprising a master brake cylinder (5), a hydraulic unit (9) and a plurality of wheel brakes (RR, FL, FR, RL), the hydraulic unit(9) comprising at least one brake circuit (BC1, BC2) for brake pressure modulation in the wheel brakes (RR, FL, FR, RL). The invention further relates to a corresponding operating method for a braking system (1) of this type. A bistable solenoid valve (10) is associated with at least one wheel brake (RR, FL, FR, RL), which valve is looped into the corresponding fluid channel, immediately upstreamof the associated wheel brake (RR, FL, FR, RL), and in a de-energized open position enables brake pressure modulation in the associated wheel brake (RR, FL, FR, RL), and in a de-energized closed position seals a current brake pressure in the associated wheel brake (RR, FL, FR, RL), wherein a hydraulic force (FH) brought about by the sealed-in brake pressure acts in a seat-opening manner in the corresponding bistable solenoid valve (10).
本发明涉及一种用于车辆的液压制动系统(1),所述液压制动系统具有主制动缸(5)、液压单元(9)和多个车轮制动器(RR、FL、FR、RL),其中,所述液压单元(9)包括至少一个用于所述车轮制动器(RR、FL、FR、RL)中的制动压力调制的制动回路(BC1、BC2),并且本发明涉及一种用于这种制动系统(1)的相应的运行方法。在此,至少一个车轮制动器(RR、FL、FR、RL)配备有双稳态电磁阀(10),该电磁阀直接在所配属的车轮制动器(RR、FL、FR、RL)上游接入到相应的流体通道中,并且在无电流打开位置中实现在所配属的车轮制动器(RR、FL、FR、RL)中的制动压力调制,并且在无电流闭合位置中将当前的制动压力锁定在所配属的车轮制动器(RR、FL、FR、RL)中,其中,通过锁定的制动压力引起的液压力(FH)以打开阀座的方式在相应的双稳态电磁阀(10)中起作用。
