摘　　要：通过分析基于P2方案的混合动力汽车电机起动发动机的过程,提出变速箱在此过程中的控制逻辑,变换变速箱控制参考扭矩为驾驶员期望扭矩,分两阶段控制,确保过程中整车驾驶舒适平顺。试验结果表明:过程中电机成功起动发动机,电机和变速箱扭矩平顺,车速未突变,说明该控制策略的正确性和合理性。The process of the P2 hybrid vehicle e-motor starting the engine was analyzed.The transmission control strategy in this process was raised.The transmission controller refer torque was changed to drive demand torque,with a two phase control strategy,to make sure the vehicle driveability.The test results show the e-motor starts the engine successfully,and e-motor and transmission torque change smoothly,the vehicle speed has no big change.It is verified the control strategy is right and rationality.
