The invention discloses an active pressure release valve control method for air conditioner joint control, and relates to the technical field of vehicle engineering. If it is obtained that the vehicle is in the normal running mode, the vehicle door opening and closing state, the vehicle window opening and closing state, the air conditioner running state and in-vehicle environment information are detected; under the working conditions that a vehicle door is closed, a vehicle window is closed and an air conditioner is started, when the in-vehicle environment information parameter reaches a preset threshold value, the pressure release valve is controlled to be closed; when the in-vehicle environment parameters do not reach the preset threshold value, the pressure release valve is controlled to be opened or intermittently opened; if it is obtained that the vehicle is in the uphill and downhill mode, in-vehicle environment information is detected; when the in-vehicle environment information parameter reaches a preset threshold value, the pressure release valve is controlled to be in a closed state, when the in-vehicle environment information parameter exceeds the preset threshold value, the pressure release valve is controlled to release pressure in a small-opening, multi-frequency and staged mode, and when the in-vehicle environment information is abnormal, the opening degree of the pressure release valve is controlled, air conditioner external circulation is started, and air pressure inside and outside the vehicle is balanced.

    本申请公开了一种空调联控的主动式泄压阀控制方法,涉及车辆工程技术领域,具体包括获取车辆的工作模式;若获取到车辆处于正常行驶模式,检测车门开闭状态、车窗开闭状态、空调运行状态和车内环境信息;当车门闭合、车窗闭合和空调开启工况下:车内环境信息参数达到预设阈值时,控制泄压阀闭合;车内环境参数未达到预设阈值时,控制泄压阀开启或者间歇开启;若获取到车辆处于上下坡模式时,检测车内环境信息;当车内环境信息参数达到预设阈值时,控制泄压阀处于闭合状态,当车内环境信息参数超过预设阈值时,控制泄压阀小开度、多频次、分阶段进行泄压,当车内环境信息出现异常时,控制泄压阀的开度并开启空调外循环,使得车内外气压平衡。
