The invention relates to the technical field of vehicle brake control and particularly discloses an electric control hydraulic system capable of achieving bidirectional pressure buildup. The system comprises a liquid storage pot, wherein working liquid is arranged in the liquid storage pot; a braking assembly which is used for braking the wheels; a power-assisted cylinder which comprises a power-assisted cylinder body with a power-assisted piston cavity and a power-assisted piston located in the power-assisted piston cavity in a sliding mode, the power-assisted piston divides the power-assisted piston cavity into a first cavity and a second cavity which are variable in volume, the liquid storage pot can communicate with the first cavity and the second cavity in a one-way mode, and the second cavity can communicate with the brake assembly in a one-way mode; and a first control valve which is arranged between the first cavity and the brake assembly, and the first control valve is used for controlling connection or disconnection between the first cavity and the brake assembly. According to the electric control hydraulic system capable of achieving two-way pressure buildup, a problem that the braking effect is poor due to insufficient braking fluid is solved.

    本发明涉及车辆制动控制技术领域,具体公开了一种可双向建压的电控液压系统,包括储液壶,储液壶内设置有工作液;制动组件,制动组件用于对车轮制动;助力缸,助力缸包括具有助力活塞腔的助力缸缸体,以及滑动位于助力活塞腔中的助力活塞,助力活塞将助力活塞腔分隔为容积可变的第一腔和第二腔,储液壶能单向连通于第一腔和第二腔,第二腔能单向连通于制动组件;第一控制阀,设置于第一腔和制动组件之间,且第一控制阀用于控制第一腔和制动组件之间的连通或断开。该可双向建压的电控液压系统解决了制动液不足情况导致的制动效果不佳的情况。
