An engine start control method in a shift process of a hybrid electric vehicle, the hybrid electric vehicle comprising an engine, a drive motor, and a clutch provided between the engine and the drive motor, the control method comprising: disengaging a synchronizer of a gearbox (S410); a step (S420) for controlling the torque capacity of the clutch so as to adjust the rotational speed of the engine from when the synchronizer is disengaged; and when the rotation speed of the engine reaches the preset rotation speed, starting the engine (S430). Thus, the engine can be started in time, thereby improving drivability. The invention further discloses an engine starting control device in the gear shifting process of the hybrid electric vehicle.
一种混合动力汽车换档过程中的发动机启动控制方法,混合动力汽车包括发动机、驱动电机、以及设置在发动机和驱动电机之间的离合器,控制方法包括:使变速箱的同步器分离(S410);自同步器分离时起,对离合器的扭矩容量进行控制以调整发动机的转速(S420);在发动机的转速达到预定转速时,启动发动机(S430)。由此,能够及时启动发动机,从而改善驾驶性能。还公开了一种混合动力汽车换档过程中的发动机启动控制装置。
