The invention belongs to the technical field of automobiles, and particularly relates to a toe-in control arm, a five-connecting-rod rear suspension system and a vehicle, the toe-in control arm comprises a toe-in control arm fixing pipe, and two liquid inlet and outlet holes communicated with an inner cavity of the toe-in control arm fixing pipe are formed in the side end of the toe-in control arm fixing pipe in the axial direction at intervals; one end of the toe-in control arm piston rod extends into the toe-in control arm fixing pipe and is connected with a toe-in control arm piston located in the toe-in control arm fixing pipe, and the toe-in control arm piston is located between the two liquid inlet and outlet holes; the electronic brake control system is communicated with the two liquid inlet and outlet holes, and the electronic brake control system is further in communication connection with a front steering engine through a CAN bus and used for controlling the amount of brake liquid entering and exiting the toe-in control arm fixing pipe based on signals of the front steering engine so as to drive the toe-in control arm piston rod to move. The length of the toe-in control arm can be dynamically and timely adjusted, the design difficulty and cost of the auxiliary frame are reduced, and the weight of the whole vehicle is reduced.

    本发明属于汽车技术领域,尤其是涉及一种前束控制臂、五连杆后悬架系统及车辆,前束控制臂包括前束控制臂固定管,其侧端沿轴向间隔设置有与其内腔连通的两个进出液孔;前束控制臂活塞杆,其一端伸入所述前束控制臂固定管内,与位于所述前束控制臂固定管内的前束控制臂活塞连接,所述前束控制臂活塞位于两个进出液孔之间;以及电子制动控制系统,与两个进出液孔连通,所述电子制动控制系统还通过CAN总线与前转向机通信连接,用于基于所述前转向机的信号,控制进出前束控制臂固定管内的制动液量,以驱动所述前束控制臂活塞杆移动。本发明可动态适时调节前束控制臂的长度,降低了副车架的设计难度及成本,减轻了整车重量。
