The invention provides a control method, system and device for a semi-active suspension of a vehicle, and is applied to a smooth regulator. The control method comprises the steps that the initial driving current of a shock absorber in the semi-active suspension of the vehicle to be controlled and the operation condition information of the vehicle are obtained; the timer collects the running time of the to-be-controlled vehicle according to the running condition information; an enable marker analyzes the travel time and determines an enable marker state of a smooth drive current by determining a target timer; a smooth current calculator determines a smooth driving current by using the initial driving current, a preset smooth coefficient and a preset time sequence according to the enabling mark state; and the current synthesizer determines a target driving current used for driving the shock absorber from an initial driving current and a smooth driving current according to the enabling mark state. Therefore, in the semi-active suspension control system, the smoothness of current switching is improved through a method of smoothly adjusting the current, so that the comfort of a driver and passengers is improved.
