The invention discloses a power assembly of a vehicle, the vehicle and a control method of the vehicle. The power assembly of the vehicle comprises a warm air system, a first cooling liquid channel is communicated between the battery motor system and the warm air system; the engine is provided with an exhaust pipe, and a second cooling liquid channel is communicated between the engine and the warm air system; the heat energy recovery device selectively recovers heat energy of the exhaust pipe so as to heat the cooling liquid in the heat energy recovery device, and a third cooling liquid channel is arranged between the heat energy recovery device and the warm air system; and the controller is electrically connected with the heat energy recovery device, the first cooling liquid channel, the second cooling liquid channel and the third cooling liquid channel. Therefore, the heat energy in the tail gas exhausted by the engine can be fully utilized, the heat efficiency of the whole vehicle can be improved, the influence of the low-temperature environment on the power assembly can be resisted, and even if the vehicle runs in the low-temperature environment, the high heat efficiency and the long endurance mileage can be kept.

    本发明公开了一种车辆的动力总成、车辆和车辆的控制方法,车辆的动力总成包括:暖风系统;电池电机系统,电池电机系统与暖风系统之间连通有第一冷却液通道;发动机,发动机设置有排气管,发动机与暖风系统之间连通有第二冷却液通道;热能回收装置,热能回收装置选择性地回收排气管的热能,以对热能回收装置内的冷却液加热,热能回收装置与暖风系统之间设置有第三冷却液通道;控制器,控制器分别与热能回收装置、第一冷却液通道、第二冷却液通道和第三冷却液通道电连接。由此,可以充分利用发动机排出的尾气中的热能,可以提高整车热效率,抵御低温环境对动力总成的影响,即使车辆在低温环境中行驶,也能保持较高的热效率及较高的续航里程。
