The invention relates to the technical field of automobile auxiliary oil pumps, and in particular relates to an auxiliary oil pump device for a hybrid electric vehicle and a control method. The auxiliary oil pump device comprises an engine and a motor, the output end of one side of the engine is fixedly connected with a clutch, the input end of the side, away from the engine, of the clutch is fixedly connected with the output end of one side of the motor, and a gearbox is arranged on the side, away from the clutch, of the motor. The auxiliary oil pump device has the advantages that the stepless speed regulation motor, the auxiliary oil pump and a power regulator are arranged, an oil pressure sensor is arranged on one side of the clutch, the pressure sensing end of the oil pressure sensor is located in the clutch, and the electric signal output end of the oil pressure sensor is electrically connected with the signal input end of the power regulator; and the situation that when oil pressure in the clutch is lost slowly, oil supply of the auxiliary oil pump is too fast, pressure is too large, the oil pressure in the clutch is lost rapidly, oil supply of the auxiliary oil pump is too slow, oil pressure loss is too much, and the clutch cannot be used normally is prevented.
本发明涉及汽车辅助油泵技术领域,特别是一种用于混合动力汽车的辅助油泵装置及控制方法,包括发动机与电动机,所述发动机一侧的输出端固定连接有离合器,所述离合器远离发动机一侧的输入端与电动机一侧的输出端固定连接,所述电动机远离离合器的一侧设置有变速箱。本发明的优点在于:通过设置了无级调速电机、辅助油泵与功率调节器,且离合器的一侧设置有油压传感器,油压传感器的压力感受端位于离合器的内部,油压传感器的电信号输出端与功率调节器的信号输入端电性连接,防止离合器内油压流失较慢时,辅助油泵供油过快,导致压力过大,防止离合器内油压流失较快,辅助油泵供油过慢,导致油压流失过多,造成离合器无法正常使用。
