The invention discloses an engine starting control method and device for a hybrid electric vehicle, the hybrid electric vehicle comprises an engine, a driving motor and a clutch arranged between the engine and the driving motor, and the method comprises the following steps: a judgment step: after the starting of the engine is completed, starting the clutch; judging whether the clutch torque capacity adaptive quantity for the starting of the engine needs to be adjusted or not; the adjusting step is used for adjusting the clutch torque capacity adaptive quantity according to the starting time data of the engine in the starting process if it is judged that the clutch torque capacity adaptive quantity needs to be adjusted, storing the adjusted clutch torque capacity adaptive quantity, and adjusting the clutch torque capacity adaptive quantity according to the stored clutch torque capacity adaptive quantity. Wherein the adjusted clutch torque capacity adaptation amount is used for next starting of the engine. Therefore, the torque capacity of the target clutch required to be used in the next start of the engine is always reasonable, so that the rotating speed of the engine can reach the threshold rotating speed in time in the next start of the engine, and the start processing of the engine can be completed in time.

    一种混合动力汽车的发动机启动控制方法及装置,该混合动力汽车包括发动机、驱动电机、以及设置在所述发动机和所述驱动电机之间的离合器,该方法包括:判断步骤,用于在完成所述发动机的本次启动后,判断是否需要调整用于所述发动机的本次启动的离合器扭矩容量适应量;调整步骤,用于如果判断为需要调整所述离合器扭矩容量适应量,则根据所述发动机在本次启动中的启动时间数据来调整所述离合器扭矩容量适应量,并对调整后的离合器扭矩容量适应量进行存储,其中调整后的离合器扭矩容量适应量用于所述发动机的下次启动。由此,使得发动机的下次启动中所要使用的目标离合器扭矩容量总是合理的,从而使得在发动机的下次启动中发动机转速能够及时地达到阈值转速,进而能够及时地完成发动机启动处理。
