The invention provides a hybrid power engine thermal management system, a control method and a vehicle, the hybrid power engine thermal management system comprises an engine cooling loop, the engine cooling loop comprises an engine cooling pipeline, and the first end of the engine cooling pipeline communicates with the inlet end of the engine cooling pipeline; the motor cooling loop comprises a motor cooling pipeline, the motor cooling pipeline and the motor are adjacently arranged for heat exchange, and the inlet end of the motor cooling pipeline selectively communicates with the inlet end of the engine cooling pipeline through a first three-way valve; wherein the engine cooling loop and the motor cooling loop have an independent heat exchange mode when heat exchange operation is independently carried out, and the engine cooling loop and the motor cooling loop have a combined heat exchange mode when the engine cooling loop and the motor cooling loop communicate with each other and carry out heat exchange operation at the same time. The motor cooling loop communicates with the engine cooling loop, the engine is heated through heat generated by locked-rotor heating of the motor, and therefore the engine can be warmed up faster.
本发明提供了一种混合动力发动机热管理系统、控制方法、车辆,包括:发动机冷却回路,发动机冷却回路包括发动机冷却管路,发动机冷却管路的第一端与发动机的冷却管路的进口端连通设置;电机冷却回路,电机冷却回路包括电机冷却管路,电机冷却管路与电机相邻地设置以进行热交换,电机冷却管路的进口端通过第一三通阀可选择地与发动机冷却管路的进口端连通设置;其中,发动机冷却回路和电机冷却回路具有相互独立进行热交换作业时的独立换热模式,以及发动机冷却回路和电机冷却回路具有相连通且同时进行热交换作业时的联合换热模式。本申请将电机冷却回路与发动机冷却回路联通,通过电机的堵转加热产生的热量来加热发动机,以实现发动机更快的暖机。
