The embodiment of the invention discloses a distributed semi-active suspension system. The distributed semi-active suspension system comprises a chassis domain controller, a communication bus and at least one damping-adjustable shock absorber assembly, the damping-adjustable shock absorber assembly comprises a shock absorber, an electromagnetic valve and a driver, damping force of the shock absorber changes along with changes of control current of the electromagnetic valve, the driver comprises an acceleration sensor module and an electromagnetic valve driving module, the acceleration sensor module is used for collecting vibration acceleration information of the suspension, and the electromagnetic valve driving module is used for driving the acceleration sensor module. The electromagnetic valve driving module is used for adjusting the control current of the electromagnetic valve; and the chassis domain controller determines a target current value according to the acceleration information and sends the target current to the electromagnetic valve driving module, so that the electromagnetic valve driving module controls the control current of the electromagnetic valve to change to the target current value. By the adoption of the technical scheme, the integration degree of the semi-active suspension system can be improved, so that the system cost can be effectively reduced, and the smoothness and handling stability of a vehicle are effectively improved.

    本发明实施例公开了一种分布式半主动悬架系统,分布式半主动悬架系统包括底盘域控制器、通讯总线和至少一个阻尼可调减振器总成;阻尼可调减振器总成包括减振器、电磁阀、驱动器,减振器的阻尼力随电磁阀控制电流大小的变化而变化,驱动器包括加速度传感器模块和电磁阀驱动模块,加速度传感器模块用于采集悬架振动加速度信息,电磁阀驱动模块用于调整电磁阀的控制电流;底盘域控制器根据加速度信息确定目标电流值,并将目标电流发送至电磁阀驱动模块,使电磁阀驱动模块控制电磁阀的控制电流变化至目标电流值。采用本发明的技术方案,可以提升半主动悬架系统的集成化程度,从而可有效降低系统成本,并有效地提高车辆的平顺性和操纵稳定性。
