IPC: B60T8/48
Filed: 2009-01-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a braking device inhibiting a sense of incongruity during vehicle stop keeping control.  <P>SOLUTION: In vehicle stop keeping control, an oil pressure control unit 78 reduces the flow of brake fluid toward a master cylinder 11 by a master cut valve 31 after a lapse of a certain time after driving a pump motor 34. Thus, when the flow of the brake fluid toward the master cylinder 11 is reduced before the flow of the brake fluid becomes stable in increasing the oil pressure at the pump motor 34, drop of the oil pressure inside the master cylinder 11 can be inhibited because the brake fluid flowing through a supply passage 26 flows to a return passage 25 by suction force of the pump motor 34. Consequently, a feeling that a brake pedal 5 is sucked toward the master cylinder 11 due to drop of the oil pressure inside the master cylinder 11 can be inhibited. As a result, a sense of incongruity during vehicle stop keeping control can be inhibited.  <P>COPYRIGHT: (C)2010,JPO&INPIT
