The invention provides a hybrid power vehicle thermal management system, a control method and a vehicle. The thermal management system comprises a heater thermal management unit, an engine thermal management loop, a passenger compartment thermal management loop and a battery thermal management loop. The heater heat management unit comprises a first switch device, a heater figure, a second switch device and a first water pump which are connected in series; the engine heat management loop comprises a third switch device, a second water pump, an engine and a radiator. Energy of a high-voltage battery energy source in the hybrid power vehicle is fully utilized to heat the water temperature of the engine, so that the engine is restarted when the water temperature of the engine reaches the optimal working temperature range of the engine, and emission and oil consumption of PN and other gaseous substances can be reduced to the maximum extent; therefore, the power performance and the economical efficiency of the whole vehicle are effectively improved.
本发明提供了一种混合动力车辆热管理系统、控制方法及车辆,热管理系统包括加热器热管理单元、发动机热管理回路、乘客舱热管理回路和电池热管理回路;加热器热管理单元包括串联连接的第一开关装置、加热器附图、第二开关装置和第一水泵;发动机热管理回路包括第三开关装置、第二水泵、发动机和散热器。本发明充分利用混合动力车辆中的高压电池能量源的能量来对发动机水温进行加热,从而能够保证发动机水温达到发动机的最佳工作温度范围内时再起动,能够最大限度地降低PN和其他气态物的排放及油耗,从而有效提高整车的动力性能和经济性。
