The invention relates to the field of vehicle hydraulic suspensions, in particular to an active hydraulic suspension liquid supply unit and a control method thereof.Solenoid valves with relatively small sizes are integrated in a valve block to form an integrated liquid supply unit, and the integrated liquid supply unit comprises a first solenoid valve, a second solenoid valve, a third solenoid valve, a fourth solenoid valve and a one-way pump; the one-way pump is powered by a one-way motor, the first oil supply end of the first electromagnetic valve and the first oil supply end of the third electromagnetic valve are both communicated with a second liquid supply port of the active hydraulic suspension liquid supply unit, and the first oil supply end of the second electromagnetic valve and the first oil supply end of the fourth electromagnetic valve are both communicated with a first liquid supply port of the active hydraulic suspension liquid supply unit. The second oil feeding ends of the third electromagnetic valve and the fourth electromagnetic valve are communicated with the oil outlet end of the one-way pump, the second oil feeding ends of the first electromagnetic valve and the second electromagnetic valve are communicated with the oil inlet end of the one-way pump, control modes of different modes can be provided for a suspension according to different conditions, and therefore various defects of a suspension liquid supply system in the prior art are overcome.
