The invention provides an engine warming-up control method and system and an automobile, and the method comprises the steps: after an in-automobile heating mode is started, detecting the water temperature of an engine, and starting to calculate the starting time of the in-automobile heating mode through a timer; if the water temperature of the engine is smaller than the first preset temperature T1 and the starting time t of the vehicle heating mode is smaller than or equal to the first preset duration, a cold and warm air door mode of the heating ventilation air conditioner assembly is adjusted to be a full-cold mode, a face blowing and defrosting air door is closed, a foot blowing air door mode is adjusted to be a full-open mode, and an internal and external circulation air door mode is adjusted to be an internal circulation mode; the air volume gear of the air blower assembly is set as a preset gear; circulating air enters the heating ventilation air conditioner from the air opening of the inner circulating air door, passes through the air blower assembly, then flows through the evaporator core body, passes through an internal flow channel of the heating ventilation air conditioner and finally is blown into a vehicle from the front-row foot blowing air opening and the rear-row foot blowing air opening, so that the water temperature rise of an engine is accelerated.

    本发明提供了一种发动机暖机控制方法、系统及汽车,该方法包括:当车内采暖模式启动后,检测发动机水温,并通过计时器开始计算车内采暖模式启动时间;若发动机水温小于第一预设温度T1且车辆采暖模式启动时间t小于或等于第一预设时长,调整暖通空调总成的冷暖风门模式为全冷模式、吹面及除霜风门关闭、吹脚风门模式为全开模式、内外循环风门模式为内循环模式,并设置鼓风机总成的风量档位为预设档位;循环风从内循环风门的风口进入暖通空调,经过鼓风机总成后,流经蒸发器芯体,在通过暖通空调内部流道,最终从前排吹脚风口和后排吹脚风口吹至车内,以加快发动机水温上升。
