The invention relates to an engine starting control method and device for a hybrid electric vehicle, and the method comprises the steps: after the starting of an engine is completed, if it is judged that starting time data meets preset conditions, calculating a first coefficient corresponding to the working temperature of the engine during the starting according to the starting time data; and determining that the clutch torque capacity adaptive quantity needs to be adjusted according to the first coefficient, adjusting the clutch torque capacity adaptive quantity corresponding to the working temperature according to the first coefficient and a preset compensation quantity, and correspondingly storing the adjusted clutch torque capacity adaptive quantity and the working temperature, wherein the adjusted adaptive quantity of the clutch torque capacity is used for next starting of the engine corresponding to the working temperature, so that frequent adjustment of the adaptive quantity of the clutch torque capacity can be avoided, the adaptive quantity of the clutch torque capacity can be converged at different temperatures, and the drivability is improved.

    本申请涉及混合动力汽车的发动机启动控制方法及装置,该方法包括:在完成所述发动机的本次启动后,若判断为所述启动时间数据满足所述预定条件,则根据所述启动时间数据计算与发动机的本次启动时的工作温度相对应的第一系数;根据所述第一系数确定为需要调整所述离合器扭矩容量适应量,则根据所述第一系数和预定补偿量来调整所述工作温度对应的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和所述工作温度进行对应存储,其中调整后的离合器扭矩容量适应量用于所述发动机对应于所述工作温度的下次启动,由此,既可避免频繁地调整离合器扭矩容量适应量,又能使离合器扭矩容量适应量在不同温度下收敛,提高驾驶性能。
