The invention relates to a vehicle steering hydraulic pipeline system and a control method thereof. A common section comprises a first communication valve, a steering oil tank, a steering oil pump and a second communication valve which are sequentially connected through pipelines. The first oil supply section comprises a first power-assisted steering part used for being connected with front wheels of a vehicle, and the first oil supply section and the common section form a first loop. The second oil supply section comprises a normally-closed connecting valve and a second power-assisted steering part which are sequentially connected through a pipeline, and the second oil supply section and the common section form a second loop; the control device is connected with the normally-closed connecting valve and used for controlling opening or closing of the normally-closed connecting valve so as to connect or disconnect the second loop. Due to the fact that one steering oil tank and one steering oil pump are used, pressure consistency and oil product consistency can be guaranteed, the pressure oil product difference of two oil supply systems is avoided, power consumption can be reduced, and hydraulic power can be provided during active steering of the rear axle in cooperation with a corresponding adjustment and control strategy.
本申请涉及一种车辆转向液压管路系统及其控制方法,包括:共用段包括通过管道依次连接的第一连通阀、转向油罐、转向油泵和第二连通阀;第一供油段包括用于和车辆前轮连接的第一转向助力件,第一供油段与共用段形成第一回路;第二供油段包括通过管道依次连接的常闭连接阀和第二转向助力件,第二供油段与共用段形成第二回路;控制装置与常闭连接阀连接,并用于控制常闭连接阀的开启或关闭,以连通或断开第二回路;由于用一个转向油罐和转向油泵,能够保证压力一致,油品一致,避免设置两个供油系统的压力油品差异,可降低功耗,配合相适应的调控制策略,可在后桥主动转向时提供液压动力。
