The determination includes one or more of: the pressure sensor and the infrared sensor are used for judging whether people are in the vehicle, the concentration of carbon dioxide is greater than a preset value, the concentration of carbon monoxide is greater than a preset value and the concentration of formaldehyde is greater than a preset value. As an example, the predetermined values of carbon dioxide concentration, carbon monoxide concentration, and formaldehyde concentration may be preset with reference to the regulations of "indoor air quality standards" in our country (for example, GB/T18883-2002). For example, the predetermined carbon dioxide, carbon monoxide and formaldehyde concentrations may be selected from 10mg/m for carbon monoxide, 0.1% for carbon dioxide and 0.1mg/m for formaldehyde respectively. However, it is understood that the predetermined values of the carbon dioxide concentration, the carbon monoxide concentration and the formaldehyde concentration may be changed according to the change of the indoor air quality standard in China.
