The invention provides a pressure release valve control method, a pressure release valve control device and a pressure release valve control system, and relates to the technical field of vehicles. According to the method, whether the pressure release valve is opened or not is judged through the vehicle speed and the vehicle leakage grade, and the influence of the vehicle speed and the vehicle leakage grade on road noise and passenger ear pressing feeling is comprehensively considered. And meanwhile, the vehicle leakage level is determined at least according to the vehicle locking signal, the internal and external air pressure difference of the vehicle under the current vehicle condition is judged in time, the pressure relief judgment process is optimized, and the problem of pressure relief lag can be well avoided. Besides, according to the technical scheme, at least one part of blades of the pressure release valve can be controlled to be opened in response to the opening condition of the pressure release valve, and all the blades of the pressure release valve can be controlled to be closed in response to the opening condition of the pressure release valve, so that balance between reduction of ear pressure of a vehicle passenger and reduction of road noise is achieved, the riding comfort is improved, and the user experience is improved. And meanwhile, the road noise performance is excellent.

    本公开提供一种泄压阀控制方法、泄压阀控制装置及泄压阀控制系统,涉及车辆技术领域。该方法通过车辆速度及车辆泄露等级判定是否开启泄压阀,综合考虑了车速及车辆泄露等级对路噪和乘员压耳感的影响。同时,至少根据车辆锁定信号确定车辆泄露等级,及时判断当前车况下车内外气压差,优化了泄压判断过程,能够较好地避免泄压滞后问题。另外,本公开的技术方案能够响应于符合泄压阀开启条件控制泄压阀的至少一部分叶片打开,响应于不符合泄压阀开启条件控制泄压阀的全部叶片关闭,从而在降低车辆乘员耳压感和降低路噪之间达到平衡,提升乘车舒适性,同时具有优异的路噪性能表现。
