The invention discloses a full-active suspension control method and device. The method comprises the steps that running state information of a vehicle is monitored in real time; obtaining a vehicle body state and a suspension state of the vehicle based on the sensor signal; demand force parameters of the vehicle suspension in the multiple vehicle frame movement directions are determined based on the sprung speeds, the vertical relative displacements and the vehicle driving signals corresponding to the multiple vehicle frame movement directions; and determining a control signal of the vehicle suspension based on each demand force parameter in combination with an effective output acting force of an actuator of the vehicle suspension. According to the method, demand force parameters of a vehicle suspension in multiple vehicle frame movement directions are obtained based on the vehicle body state and the suspension state of a vehicle, and acting force generated by the vehicle suspension in all the vehicle frame movement directions is controlled based on all the demand force parameters and effective output acting force of an actuator as reference bases. Therefore, the stable running of the vehicle is maintained, and the control precision of the full-active suspension is effectively improved.
