PURPOSE:To provide a compact hydraulic pressure controller for a vehicle which can perform antilock control and traction control, being applicable to a front-wheel driving car having a pipe composed of two systems, with one front wheel as one system and other front wheel as the other system. CONSTITUTION:This relates to a hydraulic pressure controller for a vehicle, where normally opened type first and second opening/closing solenoid valves V11 and V12, and V21 and V22, electric pumps P1 and P2, and orifices O11 and O12, and 0 21 and 022 are installed, respectively, in braking fluid pressure circuits 20 and 30. A normally opened type third solenoid valves V13 and V23 are interposed in the side section of the master cylinder of hydraulic circuits 23 and 33, and reservoirs R1 and R2 for storing brake fluid in advance are connected to hydraulic circuits 26 and 36, and check valves 43 and 53 for checking the flow to the side of wheel cylinders are provided in hydraulic circuits 25 and 35 where orifices O12 and O22 are interposed. |
