| 摘 要： | 在研究P2双离合器变速器混合动力构型发动机启动控制理论的基础上，设计了P2混合动力总成发动机启动动态工况的控制策略，给出了相应控制过程的动力控制目标值计算公式及相应的分析。通过对所设计的启动控制策略进行仿真及实车测试，验证了该控制策略能有效地实现发动机的启动功能。同时由实车测试车辆的纵向加速度曲线可知，所设计的控制策略在车辆平顺性上也取得了很好的效果。

| 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. |
