Abstract

The present application relates to a hybrid vehicle transmission control system and a control method thereof. Since the clutch DC brush motor and the cooling and lubricating DC brush motor are connected to the clutch motor control unit and the cooling and lubricating motor control unit through two positive and negative wire harnesses respectively, and are thus separated from the transmission system controller, compared with the original DC brushless motor and the controller connected by U / V / W three-phase wire harnesses and Hall signal wire harnesses, the number of wire harness connections is significantly reduced, cost is saved, and loss is reduced. The clutch motor control unit controls the operation of the clutch DC brush motor through an H-bridge control circuit; the cooling and lubricating motor control unit controls the cooling and lubricating DC brush motor through a DC chopper control circuit; different control circuits are used for the different running direction requirements of the clutch motor and the cooling and lubricating motor. Compared with the traditional DC brushless motor using a three-phase full-bridge control algorithm, it is easier to control the DC voltage and realize motor speed control.
