The invention provides a vehicle suspension system which comprises a plurality of shock absorbers, a plurality of motor pumps and a control valve, two connectors of each shock absorber are in butt joint with a first connector and a second connector of the control valve respectively, two connectors of each motor pump are in butt joint with a third connector and a fourth connector of the control valve respectively, the first connector is communicated with the third connector, and the second connector is communicated with the fourth connector. The second interface is communicated with the fourth interface, and the control valve is used for setting the connection relation between the target third interface and the target fourth interface which are respectively connected with the interfaces of at least part of the target motor pumps so as to control the at least part of the target motor pumps to cooperatively work and enable the to-be-controlled target shock absorber to operate. The problems that in the prior art, due to the fact that a motor pump in a suspension system is difficult to provide large flow for a shock absorber, the response time of the suspension system is difficult to shorten, the motor pump is difficult to provide high pressure exceeding a preset value for the shock absorber, and when the motor pump breaks down, no alternative scheme is provided for driving the shock absorber to work are solved.
本发明提供了一种车辆的悬架系统,包括多个减震器、多个电机泵和控制阀,减震器的两个接口分别对接控制阀的第一接口和第二接口,电机泵的两个接口分别对接控制阀的第三接口和第四接口,第一接口和第三接口相连通,第二接口和第四接口相连通,控制阀用于设定至少部分目标电机泵的接口各自连接的目标第三接口和目标第四接口之间的连接关系,以控制至少部分目标电机泵协同工作,使待控制的目标减震器运作。解决了相关技术中,存在悬架系统中的电机泵难以为减震器提供大流量,导致难以减小悬架系统响应时间的问题、电机泵难以为减震器提供超出预设值的高压力的问题,以及电机泵出现故障时,没有替代方案驱动减震器工作的问题。
