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.
