<P>PROBLEM TO BE SOLVED: To apply appropriate repulsive force to a brake pedal and smoothly supply brake liquid to a liquid-pressure control device when the brake pedal is suddenly operated in a brake device, which carries out regenerative cooperations. <P>SOLUTION: The brake pedal 19 causes a master cylinder 110 to generate a brake liquid pressure, and it is supplied to wheel cylinders Ba to Bd of respective wheels. Regenerative braking is carried out by the regenerative brake device 8 with reservoir ports 166 and 167 open, and the brake liquid pressure supplied to the wheel cylinders Ba to Bd by a liquid-pressure control device 5 is adjusted to execute regenerative cooperation control. In response to a sudden operation of the brake pedal 19, appropriate repulsive force is applied by orifices of the reservoir ports 166 and 167, and the brake liquid is smoothly supplied to the liquid-pressure control device 5 by bypass passages 180 and 181, which bypass the reservoir ports 166 and 167, and non-return valves 182 and 183, thereby preventing an excessive pressure reduction in primary and secondary chambers 162 and 163. <P>COPYRIGHT: (C)2013,JPO&INPIT |
