The invention relates to the field of vehicle body posture adjusting active suspensions, in particular to a vehicle body posture adjusting active suspension actuator, a system and a control method, and the vehicle body posture adjusting active suspension actuator comprises a shock absorber, a hydraulic two-way pump, an energy accumulator and a fluid loop; the shock absorber comprises a cylinder body, a piston rod and a piston head, the piston rod and the piston head are assembled and then slidably installed in the cylinder body, and the cylinder body is divided into a rod cavity and a rodless cavity. The fluid loop comprises a first hydraulic pipeline and a second hydraulic pipeline, the first hydraulic pipeline is communicated between the rod cavity and the hydraulic two-way pump, and the second hydraulic pipeline is communicated between the rodless cavity and the hydraulic two-way pump; a first hydraulic branch and a second hydraulic branch are sequentially connected to the fluid loop in parallel in the direction from the shock absorber to the hydraulic two-way pump. The whole device has the advantages that active output force can be automatically changed in real time according to changes of external conditions and environments, ideal suspension performance can be obtained under various working conditions, and comfort and operation stability can be both considered.
