Abstract:Based on analysis of engine start control theory of P2 hybrid powertrain with double clutch transmissions, the control strategies of P2 hybrid powertrain engine start dynamic condition was designed. The target powertrain control value calculations and the analysis corresponding to those each control phases were proposed. It is proved that the designed control strategy may realize the engine start effectively through the simulation and vehicle tests. According to the vehicle longitudinal acceleration curves of the real vehicle tests, the designed control strategy also achieves good results in vehicle ride comfort.
