The invention provides a method for controlling start of an engine of a hybrid vehicle, which comprises the following steps: detecting a cold start working condition of the engine in response to an engine start request of the hybrid vehicle; when a cold start condition of the engine is detected, heat generated by an electric driving component of the hybrid vehicle is at least partially transferred to the engine to preheat the engine, and the electric driving component is used for providing power for the hybrid vehicle through electric power. Before heat generated by an electric drive component of the hybrid vehicle is at least partially transferred to the engine, the electric drive component is placed in a predetermined operating state, and the temperature of the electric drive component is continuously monitored during warm-up of the engine. Based on the temperature of the electric driving component, the electric driving component is controlled to temporarily exit the preset operation state and enter the preset operation state again; the engine is controlled to start when the engine is warmed up such that an engine start condition is reached.

    本发明提出一种用于控制混合动力车辆的发动机启动的方法,包括:响应于混合动力车辆的发动机启动请求,检测发动机的冷启动工况;在检测到发动机的冷启动工况的情况下,将由混合动力车辆的电驱动部件产生的热量至少部分地传递至发动机,以对发动机预热,电驱动部件用于通过电力来为混合动力车辆提供动力,在将混合动力车辆的电驱动部件产生的热量至少部分地传递至发动机之前,将电驱动部件置于预定运行状态,在对发动机预热期间持续地监测电驱动部件的温度,基于电驱动部件的温度控制电驱动部件临时退出预定运行状态以及重新进入预定运行状态;在发动机被预热至以使得达到发动机启动条件时,控制发动机启动。
