Problems solved by technology

[0002] When the car is driven in a low temperature environment, because the outside temperature is lower than the inside temperature, the front windshield of the car is prone to fogging and frosting, thus blocking the driver's sight and affecting driving safety
The driver generally needs manual operation to clean the windshield, which requires the driver to clean it manually, which can easily cause traffic accidents
Although some existing models are equipped with defoggers and defrosters, they still need to be manually switched by the driver, which is troublesome to operate. Moreover, there are many functions integrated in the existing models, and there are more and more start switches. When the driver Turning on the corresponding switch while driving may also cause traffic accidents, and it does not conform to the development trend of intelligence

[0045] see figure 1 , an embodiment of the present invention provides a method for controlling a vehicle air conditioner, including:

[0046] Step 101, obtaining real-time image information of the front windshield;

[0047] Step 102, according to the real-time image information, control the vehicle air conditioning system to activate or deactivate the defrosting and defogging of the front windshield by warm air.

[0048] In the control method of the vehicle air conditioner in the embodiment of the present invention, the real-time image information of the front windshield is obtained, the image information of the front windshield is recognized by image processing technology, and the front windshield is heated by controlling the air conditioning system to start the warm air. When there is no frost and no fog, control it to close, so as to realize automatic and real-time defogging and defrosting functions, and meet the needs of intelligent development of automobiles. In the con...

no. 2 example

[0051] see figure 2 For the first embodiment, the step of controlling the vehicle air conditioning system to activate or deactivate the warm air to defrost and defog the front windshield according to the real-time image information includes:

[0052] Step 201, performing preset processing on the real-time image information to obtain status information of the front windshield;

[0053] Step 202, when the state information indicates that the front windshield is currently in a state of frost and / or fogging, control the vehicle air conditioning system to start warm air to defrost and defog the front windshield;

[0054] Step 203 , when the status information indicates that the front windshield is currently in a non-frost and / or non-fog state, control the vehicle air conditioning system to turn off warm air to defrost and defog the front windshield.

[0055] Compared with the first embodiment, in this embodiment, how to control the vehicle air conditioning system to activate or d...

no. 3 example

[0058] see image 3 , For the second embodiment, the preset processing is performed on the real-time image information, and the step of obtaining the state information of the front windshield includes:

[0059] Step 301, performing a first preset process on the real-time image information to obtain processed image information;

[0060] Step 302, performing binarization on the processed image information to obtain a binary image;

[0061] Step 303, performing mathematical morphological operations on the binary image, and calculating the image area of ​​the frosting and / or fogging area in the binary image;

[0062] Step 304, comparing the value of the image area with a preset area value to obtain status information of the front windshield.

[0063] In this embodiment, the preprocessing of image information is explained in detail, because the gray value of the frosted and fogged area of ​​the glass is different from that of the non-frosted and fogged area, and the binarization ...

Abstract

The invention provides a control method and device for a vehicle air conditioner. The control method for the vehicle air conditioner comprises the steps that real-time image information of a front windshield is obtained; and a heater of a vehicle air conditioner system is turned on or off for defrosting and demisting of the front windshield according to the real-time image information. According to the control method and device for the vehicle air conditioner, the state of the front windshield is identified by means of the image processing technology, and the front windshield is defrosted and demisted through the heater so that the functions of automatic and real-time defrosting and demisting can be achieved in this way, and the demand for automobile intelligent development is met.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and device for a vehicle air conditioner. Background technique [0002] When the car is driven in a low temperature environment, because the temperature outside the car is lower than the temperature inside the car, the front windshield of the car is prone to fogging and frosting, thus blocking the driver's sight and affecting driving safety. Drivers generally need manual operations to clean the windshield, which requires the driver to manually clean up, which can easily cause traffic accidents. Although some existing models are equipped with defoggers and defrosters, they still need to be manually switched by the driver, which is troublesome to operate. Moreover, there are many functions integrated in the existing models, and there are more and more start switches. When the driver Turning on the corresponding switch during driving may also cause traffic acci...
