The invention provides a control method and device for a full-active suspension and a vehicle, the full-active suspension comprises a plurality of sub-suspensions, the control method comprises the steps that the internal pressure of air springs of the sub-suspensions is obtained, and sprung mass is calculated according to the internal pressure and the pre-stored effective cross sectional area of the air springs; the vertical vibration acceleration of the sub-suspension at the current moment is obtained, and theoretical active force is calculated according to the sprung mass and the vibration acceleration; and a control instruction is sent according to the theoretical main power, so that the theoretical main power is applied to the sub-suspension. According to the control method and device of the full-active suspension and the vehicle, the method and device are simple and convenient, the theoretical active force can be quickly and effectively calculated, so that the actual active force of the sub-suspension reaches the theoretical active force, vehicle body vibration is reduced, vehicle smoothness is improved, and user experience is high.
