Automobile automatic defogging system and control method thereof

Abstract

The invention provides an automobile automatic defogging system and a control method thereof, belongs to the automobile technical field and solves the problem that the defrosting system in the prior art is not smart enough. The system comprises a centralized controller, wherein the centralized controller is connected to a first temperature sensor, a first humidity sensor, a second humidity sensor and an air-conditioning system controller; the air-conditioning system controller controls the air-conditioning system to start the automatic defrosting mode upon determining that the humidity outside the automobile is higher than the humidity inside the automobile; and the centralized controller compares the temperature in the automobile with a predetermined reference temperature, and adjusts an air-conditioning system control instruction according to the temperature in the automobile and makes adjustment on the air-conditioning temperature, air direction and air quantity of the automatic defrosting mode. The method comprises the steps of: (1) starting the automatic defogging system to work; (2) controlling the four door switches of the automobile to be closed; (3) starting the automatic defrosting mode; and (4) adjusting the air outlet direction, the air outlet quantity and the air outlet temperature of the air-conditioning system. The system and the method realize full smart defrosting while keeping the environment in the automobile comfortable.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an automatic defogging system for automobiles and a control method thereof. Background technique [0002] In rainy or snowy days, when people are driving, there are often water droplets or fog on the windshield, which affects the driver's vision. Usually, the driver will open the window, but not too much. Cold, the second is that there is rain coming in, and the third is that the defrosting effect cannot be achieved immediately; the driver may also turn on the air conditioner to defog, turn the series of air conditioner switches on the central control panel, and operate the car while driving without seeing the road clearly. The air conditioner is switched on and off, which seriously affects driving safety; there is also the use of towels or paper towels to wipe the inner surface of the window for defogging. [0003] The above-mentioned various methods have played the function ...

AI Technical Summary

Problems solved by technology

The device also activates a certain automatic defogging function, but only the signals detected by the above two sensors are used as the judgment basis to realize automatic defrosting. can be uncomfortable under fortification

Therefore, the device is not comprehensive and intelligent enough
