摘　　要：为改善混合动力汽车的驾驶性能,提高混合动力汽车的动力响应速度,研究混合动力汽车发动机起动控制策略。构建P2构型混合动力系统结构,以此作为混合动力汽车动力系统,利用这一动力系统结构,分析混合动力汽车在纯电动运行模式、发动机单独驱动运行模式以及联合驱动等运行模式下不同汽车参数的变化情况,根据不同参数变化,构建发动机起动控制策略,通过PID模糊控制离合器油压以及动力源转矩协调控制,实现混合动力汽车发动机起动控制。经仿真实验验证:在该控制策略下,可在发动机起动过程中产生较小的冲击度,保障发动机起动稳定;且能够在起动时迅速实现发动机与电机之间的转速变化,为此具有良好的控制性能。In order to improve the driving performance and dynamic response speed of hybrid electric vehicle,the engine starting control strategy of hybrid electric vehicle was studied.The P2 configuration hybrid power system structure is constructed as the power system of the hybrid electric vehicle.Using this power system structure,the changes of different vehicle parameters in the pure electric operation mode,the single engine drive operation mode and the combined drive operation mode of the hybrid electric vehicle are analyzed,and the engine starting control strategy is constructed according to the changes of different parameters.By PID fuzzy control of clutch oil pressure and power source torque coordination control,the engine starting control of hybrid electric vehicle is realized.The simulation results show that under this control strategy,a small impact degree can be generated during engine starting and the engine starting stability can be guaranteed.And can quickly realize the speed change between the engine and the motor when starting,so it has good control performance.
