The invention provides a high-altitude flameout prevention control method for an engine, belongs to the technical field of automobile control, and aims to solve the problems that when the altitude of a vehicle meets a preset time condition, the ambient air of the vehicle is rarefied, and if an air conditioner compressor is started, the torque of the engine is greatly consumed, and the risk of flameout of the engine is caused. And under the condition, a compressor of the vehicle-mounted air conditioner is turned off, torque consumption is reduced, and therefore the flameout risk of the engine in the plateau environment is reduced.

    本申请提供了一种发动机高海拔防熄火控制方法,属于汽车控制技术领域,当判断出车辆所处海拔高度满足预设时条件,则说明车辆所处环境空气稀薄,如果开启空调压缩机,则会大幅消耗发动机扭矩,有导致发动机熄火的风险,在这种情况下,则关闭车载空调的压缩机,减小扭矩消耗,从而降低发动机在高原环境下的熄火风险。
