The invention discloses an active pressure release valve control system and method and a vehicle, and belongs to the technical field of automobiles. Comprising the following steps that S100, whether a vehicle is in a parking state or not is detected; s200, the working state of an air conditioning system of the vehicle is obtained, and if an air conditioner is in an on state, an air pressure release valve is controlled to be completely opened; s300, whether the vehicle is in a wading working condition or not is obtained, and if the vehicle is in the wading working condition, the air pressure relief valve is controlled to be closed; and S400, the pressure difference value inside and outside the vehicle is obtained, the opening area of the air pressure release valve is calculated according to the pressure difference value inside and outside the vehicle, and the air pressure release valve is controlled to be opened to the opening area. According to the pressure release valve state corresponding to different vehicle cabin internal and external pressure differences under different use working conditions of an automobile, collaborative development among multiple performances can be achieved, the door closing sound quality is improved, and the problems of ear pressure sense and door closing force increase during door closing are solved.

    本发明公开了一种主动式泄压阀控制系统、控制方法及车辆,属于汽车技术领域。包括以下步骤:S100、检测车辆是否处于驻车状态;S200、获取车辆的空调系统的工作状态,若空调为开启状态,则控制空气泄压阀完全打开;S300、获取车辆是否处于涉水工况,若汽车处于涉水工况,则控制空气泄压阀关闭;S400、获取车辆车内外的压力差值,用车内外的压力差值计算空气泄压阀阀门的开启面积,控制空气泄压阀开启至开启面积。本发明能够针对汽车在不同使用工况下、不同车舱内外压力差对应的泄压阀状态,实现多性能间的协同开发,提升关门声品质,避免关门时的“耳压感”和关门力变大的问题。
