液圧ブレーキシステム
Document Type and Number:
Japanese Patent JP5655938
Kind Code:
B2
Abstract:
The purpose of the present invention is to make control hunting less likely to occur in a hydraulic brake system provided with drum brakes. In a regenerative cooperative control, a separate valve 134 is placed in its closed state, an accumulator cutoff valve 136 is placed in its closed state, a master cutoff valve 138 is placed in its open state, and a first common hydraulic-pressure control valve 140 is controlled. That is, in the regenerative cooperative control, brake cylinders 52FL, 52FR of the drum brakes 50RL, 50RR are isolated from a common hydraulic-pressure sensor 226, so even if pulsation occurs in the drum brakes 50RL, 50RR, the control of the first common hydraulic pressure control valve 140 will not be affected. Accordingly, even if the drum brakes 50RL, 50RR are used, the control hunting can be made less likely to be generated.
