This scheme adopted a higher power of the motor and an electric automatic clutch between the engine and motor, a manual clutch was fixed between motor and transmission. Based on the theory of vehicle dynamics in typical Chinese urban roads and so on, many kinds of needed motivations were calculated, and a simulink model of the double-clutche hybrid vehicle under the transient condition was established, and in the vehicle’s transient accelerate condition, coordinated torque was distributed through the clutch. Simulation and experimental results indicate that the new scheme improves state-transition processes smoothly, improves the transient process of the torque response speed, and shortens the accelerating time.
