Patent ID: 7578564

Claim:
A brake hydraulic pressure control unit for a vehicle comprising: a hydraulic block including a plurality of pumps each for drawing and feeding brake fluid to one of wheel cylinders configured to be mounted to respective wheels of the vehicle, and a plurality of solenoid valves for selectively opening and closing brake fluid passages extending from a master cylinder to the respective wheel cylinders and brake fluid passages extending from the respective wheel cylinders to a reservoir, and for individually controlling hydraulic pressures in the respective wheel cylinders, said plurality of pumps comprising first and second pumps for first and second hydraulic circuits, respectively; motors for driving said first and second pumps, respectively; and an electronic control unit for controlling said solenoid valves and said motors, said hydraulic block having ports connected to the master cylinder, the wheel cylinders and the reservoir, respectively, at an upper portion thereof; wherein said motors are provided at a first end of said hydraulic block so as to be aligned along a vertical axis of said hydraulic block, and said plurality of solenoid valves and said electronic control unit are provided at a second end of said hydraulic block that is opposite to said first end; and wherein when an end surface of said hydraulic block at said second end is viewed from a direction perpendicular to said end surface, component parts forming said first hydraulic circuit are provided in a first vertically elongated area on the right-hand side of pump mounting portions in which said pumps are mounted, and component parts forming said second hydraulic circuit are provided in a second vertically elongated area on the left-hand side of said pump mounting portions, said component parts in each of said first and second vertically elongated areas overlapping each other in a direction perpendicular to said vertical axis.
