<p><P>PROBLEM TO BE SOLVED: To miniaturize a cam or an output shaft, and to miniaturize a device as a whole, and to reduce cost. <P>SOLUTION: This hydraulic pressure control device for a vehicle includes a hydraulic pressure system partitioned into a first hydraulic pressure system and a second hydraulic pressure system, and includes a camshaft driven by an electric motor, eccentric cams 211a, 211b rotated and driven by the camshaft, and at least four or more even number of plunger pumps 6A-6F generating hydraulic pressure in the first and second hydraulic pressure systems different in phase by the eccentric cams 211a, 211b. The plunger pumps is composed of a plurality of first plunger pumps 6A, 6C, 6E, and the second plunger pumps 6B, 6D, 6F of the same numbers. The number of eccentric cams 211a, 211b is plurality, and each time they are rotated and driven one time, all of the plunger pumps 6A-6F are driven, and the hydraulic pressure is generated evenly in the first and second hydraulic pressure systems. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
