Vehicle, ventilation system of vehicle and ventilation method applied to vehicle

Abstract

The invention discloses a ventilation method applied to a vehicle. The method includes the steps that a power-off signal generated when an ignition switch leaves an ON gear is obtained; an evaporatortemperature t1 is acquired; whether vapor can be condensed on the surface of an evaporator or not is judged according to the condition whether the evaporator temperature t1 is smaller than a preset condensation temperature or not, if the evaporator temperature t1 is smaller than the preset condensation temperature, the vapor can be condensed on the surface of the evaporator, and a next step is conducted; and a ventilation circulation mode is controlled to be an outer circulation mode, and air is blown. The above method is mainly used for power-off mildew removal of the vehicle, the problem that the evaporator of an air conditioner is mildewed is solved, the method is further used for ventilating the inside of the vehicle to reduce the temperature, and the problems that the temperature in the vehicle is too high and harmful gases are gathered are solved. In addition, the invention discloses a ventilation system and the vehicle comprising the above ventilation system.

Description

technical field [0001] The invention relates to the field of vehicle electrical system control, in particular to a ventilation method applied to vehicles. Furthermore, the invention also relates to a ventilation system and a vehicle comprising the aforementioned ventilation system. Background technique [0002] With the development of the automobile industry, people are more and more fond of using cars, but many drivers have certain problems in their car habits, especially after parking, they directly turn off the air conditioner used for cooling before locking the car and leaving. At this time, the temperature of the evaporator of the air conditioner is obviously lower than the temperature of the external environment, and a certain amount of water vapor will condense on the surface of the evaporator. If things go on like this, the evaporator will become mildewed and emit peculiar smell during use, which will affect the driver in the car. The comfort of passengers; secondly...
