发明名称 BRAKING FORCE CONTROL DEVICE FOR VEHICLE
摘要 PROBLEM TO BE SOLVED: To provide a braking force control device for a vehicle which can improve the feeling of a brake pedal operation at the ABS control time. SOLUTION: This control device has a selector valve SA3 for switching the interception and communication of a liquid passage between a master cylinder 31 and wheel cylinder 41 (41FR, 41FL, 41RR, 41RL) and at the ABS control time, the liquid passage is intercepted by the selector valve SA3 and the wheel cylinder 41 is connected to an accumulator 36 and also to brake force can be controlled by adjusting the liquid pressure of the wheel cylinder 41 (41FR, 41FL, 41RR, 41RL). This device is provided with a stroke sensor 12 for detecting the operation amount of a brake operation by a driver and at the ABS control time, when the stroke S is not a set value A or more, the liquid passage between the master cylinder 31 and wheel cylinder 41 (41FR, 41FL, 41RR, 41RL) is communicated and when the stroke S is the set value or more, the selector valve SA3 is switched so that the liquid passage is switched from the communication state to the interception state.
