The invention discloses an engine starting control method of a hybrid power vehicle and the hybrid power vehicle, and the engine starting control method of the hybrid power vehicle comprises the steps that in response to an engine starting instruction, an engine is controlled to enter a rotating speed control mode; acquiring the rotating speed of the engine and the rotating speed of the clutch; the clutch is controlled to enter a sliding friction control mode according to the difference value between the rotating speed of the engine and the rotating speed of the clutch, in the sliding friction control mode, the engine is controlled to be switched from the rotating speed control mode to the torque mode, and the compression degree of the clutch is controlled according to the difference value between the rotating speed of the engine and the rotating speed of the clutch. The speed of the engine is adjusted according to the compression degree of the clutch, so that the difference value between the rotating speed of the engine and the rotating speed of the clutch is smaller than a clutch closing threshold value; and the clutch is controlled to be closed to finish starting of the engine. By adopting the method, the closing time of the clutch can be accurately controlled, and the engine can be quickly started.

    本发明公开了一种混合动力车辆的发动机启动控制方法和混合动力车辆,混合动力车辆的发动机启动控制方法,包括:响应于发动机启动指令,控制发动机进入转速控制模式;获取发动机的转速和离合器的转速;根据发动机的转速与离合器的转速的差值控制离合器进入滑磨控制模式,其中,在滑磨控制模式下,控制发动机由转速控制模式切换为扭矩模式,并根据发动机的转速与离合器的转速的差值控制离合器的压紧程度,以通过离合器的压紧程度对发动机进行调速,使得发动机的转速与离合器的转速的差值小于离合器闭合阈值;控制离合器闭合,以完成发动机的启动。采用该方法可以精准控制离合器闭合的时机,实现快速启动发动机。
