Abstract: In the hybrid electric bus, the vehicle control system frequently switches the driving mode of the vehicle according to the working conditions, and the clutch is an important component of the drive mode switching, and its working quality determines the overall performance of the drive system. In this paper, a fuzzy control model is established to control the engagement process of clutch by analyzing and modeling the structure of the clutch and studying the evaluation index of the clutch bonding quality. In order to achieve the goal of reducing fuel consumption of hybrid electric vehicles, it is proposed to use pure electric drive on the premise of meeting the torque required for driving the vehicle. When the output torque of the motor cannot meet the driving requirements of the vehicle, the motor outputs additional torque to drive the engine. The control strategy of fuel injection ignition after reaching a certain speed. After the engine is ignited, the main and driven discs of the clutch are in a sliding state, and when the speed difference between the main and driven discs is small, they are quickly engaged to reduce impact and improve ride comfort.
