<P>PROBLEM TO BE SOLVED: To increase a W/C (wheel cylinder) pressure in emergency braking more quickly. <P>SOLUTION: When a W/C pressure does not follow an M/C (master cylinder) pressure, differential pressure control valves 16, 36 are controlled to a communication condition, so that a path R1 communicating to a main line A is included in a supply path of braking liquid from M/C 13 to W/C 14, 15, 34, 35. Accordingly, in emergency braking immediately after a start of braking, the braking liquid can be supplied from M/C 13 to W/C 14, 15, 34, 35 through the path R1 communicating to the differential control valves 16, 36. Therefore, corresponding to an increase of the M/C pressure, the W/C pressure can be increased quickly. <P>COPYRIGHT: (C)2008,JPO&INPIT |
