The invention discloses a vehicle air purification system and an in-vehicle air purification method. The purification system comprises an in-vehicle oxygen content detection device, a PM2.5 sensor, an inner circulation air door, an outer circulation air door, an activated carbon filter element and a control device. When the vehicle air conditioning system is in an automatic adjusting state, and the oxygen content in the vehicle is lower than a standard value, the control device controls the inner circulation air door to be closed, controls the outer circulation air door to be opened and switches to an outer circulation state; when the oxygen content in the vehicle is normal, the control device controls opening and closing of the inner circulation air door and the outer circulation air door according to the PM2.5 value in the vehicle and the PM2.5 value outside the vehicle, and switching of the inner circulation state and the outer circulation state is achieved. According to the purification system and the purification method provided by the invention, the air quality in the vehicle is monitored and improved by comprehensively considering indexes of PM2.5 and oxygen content, so that the supply quantity of oxygen is ensured, the PM2.5 content is reduced, the level of a driving environment in the vehicle is improved, and sterilization and disinfection can be performed through the negative ion generator.

    本发明公开了一种车用空气净化系统及车内空气净化方法,其中净化系统包括车内含氧量检测装置、PM2.5传感器、内循环风门、外循环风门、活性炭滤芯以及控制装置;车辆空调系统处于自动调节状态时:当车内含氧量低于标准值时,控制装置控制内循环风门关闭、外循环风门打开,切换至外循环状态;当车内含氧量正常时,控制装置根据车内、外PM2.5值,控制内循环风门与外循环风门的开关,实现内外循环状态的切换。本发明提供的净化系统及净化方法,通过综合考虑PM2.5以及含氧量的指标,对车内的空气质量进行监控和改善,既保证氧气的供给量,又降低了PM2.5含量,提高了车内驾驶环境的水平,并能通过负离子发生器进行灭菌消毒。
