The invention relates to an engine starting control method and device for a hybrid electric vehicle, wherein the control method comprises the steps: a basic clutch torque capacity and a clutch torquecapacity adjustment amount are determined when an engine is started, wherein the basic clutch torque capacity is determined according to the resistance torque of the engine, and the clutch torque capacity adjustment amount is determined according to clutch torque capacity used for historical starting of the engine; according to the basic clutch torque capacity and the clutch torque capacity adjustment amount, the target clutch torque capacity used for starting the engine this time is calculated; and the torque of the clutch is controlled based on the target clutch torque capacity, so that thespeed of the engine is adjusted to a threshold rotating speed, and the threshold rotating speed is the rotating speed required for starting the engine. Therefore, good drivability of engine starting can be achieved while the engine is successfully started.

    本公开涉及一种混合动力汽车的发动机启动控制方法及装置,所述控制方法包括:在启动所述发动机时,确定基本离合器扭矩容量和离合器扭矩容量调整量,其中,所述基本离合器扭矩容量根据所述发动机的阻力矩确定,所述离合器扭矩容量调整量根据所述发动机的历史启动所用的离合器扭矩容量确定;根据所述基本离合器扭矩容量和所述离合器扭矩容量调整量,计算所述发动机本次启动所用的目标离合器扭矩容量;以及基于所述目标离合器扭矩容量对所述离合器的扭矩进行控制,使所述发动机被调速至阈值转速,其中所述阈值转速是所述发动机启动所需的转速。由此,能够在成功启动发动机的同时实现发动机启动的良好驾驶性能。
