The invention relates to a dual-driving oil pump for hybrid vehicles and a control system thereof. The dual-driving oil pump comprises a pump body, a driving motor and a hydraulic oil line, and is characterized in that the pump body is provided with a left input shaft and a right input shaft; the left input shaft is connected with a driving motor by a left clutch; the right input shaft is connected with an output shaft of a hybrid speed changing box by a right clutch; and a hydraulic oil input end of the pump body is communicated with an oil tank, and a hydraulic oil output end of the pump body is communicated with each hydraulic control mechanism by a check valve. When the rotate speed of the output shaft of the hybrid speed changing box is low, and due to increasing relation between theflow and rotate speed of the oil pump, the flow of the pump body is insufficient under the condition that the oil pump is driven by the output shaft of the hybrid speed changing box. Therefore the pump body is driven by the motor when the rotate speed of the output shaft of the hybrid speed changing box is low to provide pressure oil for the operating of the hybrid speed changing box.
