The invention provides a commercial vehicle semi-active suspension control system and method, and belongs to the technical field of automobile control. A cab CDC damper; an acceleration sensor is suspended on the chassis; an acceleration sensor is suspended on the cab; the controller is used for determining first damping and second damping based on the vehicle speed, the opening degree of an accelerator pedal, the opening degree of a brake pedal, the steering wheel angle information, a chassis acceleration signal collected by the chassis suspension acceleration sensor and a cab acceleration signal collected by the cab suspension acceleration sensor, and adjusting the chassis CDC shock absorber based on the first damping and adjusting the second damping based on the cab acceleration signal collected by the cab suspension acceleration sensor. And adjust the cab CDC damper based on the second damping. The damping of the chassis CDC shock absorber and the damping of the cab CDC shock absorber are adjusted, so that the posture change of the cab is effectively restrained, and the technical problem that the riding comfort of a driver is poor due to the fact that the suspension control effect of a commercial vehicle is not ideal in the prior art is solved.
