[0026] Embodiment 1 like Figure 1 As shown, this embodiment provides a vehicle anti-fogging control method, comprising the following steps: Step S100: collecting the temperature and humidity in the vehicle, and determining the dew point temperature according to the temperature and humidity in the vehicle; in this embodiment, the temperature and humidity in the vehicle are data obtained by the vehicle control system controlling the temperature sensor and humidity sensor in the vehicle.

[0027] Step S200: Collect the temperature of the front windshield of the vehicle, and calculate the difference T between the front windshield temperature and the dew point temperature; in this embodiment, the front windshield temperature accident vehicle control system controls the data obtained by the front windshield temperature sensor.

[0028] Step S300: Determine the fogging level of the front windshield by comparing the difference T with the level threshold; it should be noted that in this step, if the difference T is within the specified temperature range, there is no risk of fogging on the front windshield of the vehicle, and the fogging level is recorded as .

[0029] Step S400: receiving a defogger program start signal, and starting a corresponding defogger mode according to the fogging level.

[0030] In this embodiment, after starting the vehicle, the control system in the vehicle can control the vehicle temperature sensor, humidity sensor and windshield temperature sensor on the vehicle to obtain the temperature and humidity in the vehicle, as well as the temperature of the vehicle windshield, and calculate the fogging level through the vehicle control system, and after receiving the defogger program start signal, start the defogger mode corresponding to the above-mentioned fogging level. In this embodiment, the fogging level of the vehicle windshield is first calculated, and then the corresponding defogger mode can be started after receiving the defogger signal. Compared with the existing defogger method, the reaction time of the driver in the vehicle to start the defogger system after seeing the fogging of the windshield is eliminated, the time when the fogging of the windshield blocks the driver's vision is shortened, and the safety performance of vehicle driving is improved.

[0034] Step S421: Determine whether the air conditioner is in the off mode.

[0035] Step S422: Feedback the operation instruction to the interaction end.

[0036] Step S4231: If the interactive end feedback agrees with the instruction.

[0037] Step S4232: Start the air conditioner to automatic mode and match the defog mode corresponding to the fogging level.

[0038] Step S4241: If the interactive end feedback disagrees with the instruction.

[0039] Step S4242: The air conditioner remains off.

[0040] Step S431: Determine whether the air conditioner is in manual mode.

[0041] Step S432: Control the compressor to control the first target evaporation temperature .

[0042] In a possible implementation of this embodiment, the interactive end includes a main control screen in the vehicle, or a main control screen in the vehicle and an auxiliary screen for the co-pilot; the operation instruction includes a pop-up window instruction, which is used to be displayed on the control screen, or displayed on the main control screen and the auxiliary screen at the same time, so that the personnel in the vehicle can operate. In this embodiment, the pop-up window instruction is specifically a text box displayed on the main control screen indicating whether to start the defog mode, and a yes selection box and a no selection box located on the control box. When the pop-up window instruction is displayed on the main control screen and the auxiliary screen, it is convenient for the personnel in the vehicle to operate.

[0043] The pop-up window instruction is displayed on the main control screen for a long time, blocking the display content on the main control screen and preventing the driver from obtaining the content on the main control screen. For this reason, the operation instruction in this embodiment also includes a timing instruction, specifically a countdown box displayed on the text box, and the countdown box displays the countdown of the set time. When the countdown ends and the occupants do not operate, the text box is automatically closed and the air conditioner is not started. It should be noted that when the pop-up window instruction is displayed on the main control screen and the auxiliary screen at the same time, after the countdown of the timing instruction ends, the pop-up window display on the main control screen disappears, and the pop-up window display on the auxiliary screen is still there, so that other people in the car can operate.

[0044] In a possible implementation of this embodiment, the operating instructions also include voice instructions. When the pop-up instructions are displayed on the control screen, or displayed on the control screen and the auxiliary screen at the same time, voice instructions are issued at the same time so that the people in the car can operate through voice interaction, so that the people in the car can choose the interaction method according to the situation, thereby further ensuring the safety performance of the vehicle during driving.

[0045] In the present embodiment, when the air conditioner is in the off mode, the vehicle control system can first calculate the fogging level of the vehicle's front windshield, and feed it back to the occupants through pop-up instructions, or pop-up instructions and voice instructions. The occupants start the air conditioner to automatic mode by clicking on the contact interaction or voice interaction on the main control screen, and match the defog mode corresponding to the fogging level. Compared with the existing defog method, the reaction time of the driver in the vehicle to start the defog system after seeing the fogging of the windshield is eliminated, the redundant reaction time is reduced, the time that the fogging of the windshield blocks the driver's line of sight is shortened, and the safety performance of vehicle driving is improved.

[0047] The air conditioner is in off mode, when the fogging level is the first level When the fogging level is the first level, the operation command is fed back to the interactive end. or second level For the front windshield, which is slightly blocked and does not affect the driver's vision, some people are reluctant to start the defogger program to save energy. When the fogging level reaches the third level, When the front windshield is blocked, the driver's sight is affected, which poses a safety hazard, and the operation command needs to be fed back to the interactive end. Therefore, the user can feed back the operation command to the interactive end when the fogging level is at a certain level according to the needs, and there is no limitation here.

[0048] In a possible implementation of this embodiment, the level threshold includes three groups of fogging level arrangements distributed from low to high, namely, a low-sensitivity fogging level arrangement, a medium-sensitivity fogging level arrangement, and a high-sensitivity fogging level arrangement, as shown in the following table:

Therefore, you can choose to set a low-sensitivity fogging level arrangement, a medium-sensitivity fogging level arrangement, or a high-sensitivity fogging level arrangement in advance according to your needs, so that the front windshield can be defogged according to the setting after fogging, thereby improving the actual defog experience.

[0051] In a possible implementation of this embodiment, the defogging mode includes the first level , Second level , third level With the fourth estate The corresponding first demisting program, second demisting program, third demisting program and fourth demisting program respectively.

[0052] The first defog procedure includes starting the circulation damper motor and controlling the external circulation ratio to be no less than 40%.

[0053] The second defogger program includes starting the circulation damper motor and controlling the external circulation ratio to be no less than 60%, and controlling the compressor to control the second target evaporation temperature. .

[0054] The third defogger program includes controlling the circulation damper motor and controlling the external circulation ratio to be no less than 80%, controlling the air conditioning air outlet mode to add a window blowing mode on the basis of the current mode, and controlling the blower air volume to be no less than the first air volume threshold , control the compressor to control the third target evaporation temperature It can be understood that if the current air outlet mode is blowing on the face, the air outlet mode is controlled to blow on the face and windows to ensure the defog effect.

[0055] The fourth defogger program includes controlling the circulation damper motor and controlling the external circulation ratio to be not less than 100%, controlling the air conditioning outlet mode to be the window blowing mode, and starting the wind motor in this mode, and controlling the blower air volume to be not less than the second air volume threshold , control the compressor to control the fourth target evaporation temperature .

[0056] In the above embodiments, the circulating damper motor, the compressor, the mode wind motor and the blower are all controlled and adjusted by the vehicle control system.

[0057] In a possible implementation of this embodiment, in the third demisting program, the blower air volume is controlled to be not less than the first air volume threshold The steps include: First air volume threshold Include first specified threshold , the second specified threshold and the third specified threshold ,and < < .

[0058] If the current blower air volume increases After it is less than the first specified threshold , then increase the air volume to .

[0059] If the current blower air volume is within the first specified threshold Second specified threshold On this basis, add .

[0060] If the current blower air volume is greater than the third specified threshold , then the existing blower air volume remains unchanged. In this embodiment, the first air volume threshold Include first specified threshold , the second specified threshold and the third specified threshold In actual use, it can be adjusted according to the current air output of the vehicle's blower to avoid sudden and drastic adjustments to the blower affecting the actual experience of people in the car.

[0061] See also Figure 3 In a possible implementation of this embodiment, the air volume of the current blower increases After it is less than the first specified threshold , then increase the air volume to The steps include: Step S311: Increase the air volume based on the real-time air volume of the blower To air volume .

[0062] Step S312: If the air volume Less than the first air volume threshold , on this basis, increase the air volume To air volume .

[0063] Step S313: If the air volume Less than the first air volume threshold On this basis, increase the air volume Until the air volume is not less than the first air volume threshold .

[0064] In a possible implementation of this embodiment, in the fourth demisting procedure, the blower air volume is controlled to be not less than the second air volume threshold The steps include: If the real-time air volume of the blower is less than the second air volume threshold , then increase the blower air volume to the second air volume threshold , and maintain the blower state at this time.

[0065] If the real-time air volume of the blower is not less than the second air volume threshold , then keep the blower working at this time.

[0066] In this embodiment, the first target evaporation temperature , Second target evaporation temperature , the third target evaporation temperature With four target evaporation temperatures They are respectively taken as the smaller value between the corresponding current air-conditioning target evaporation temperature and the anti-fog target evaporation temperature, wherein the current target evaporation temperature is obtained by the automatic air-conditioning algorithm according to the current air-conditioning state setting, and the anti-fog target evaporation temperature is obtained according to the anti-fogging strategy of different fogging risk levels. Other embodiments can be selected according to needs and are not limited here. In a possible implementation of this embodiment, the difference T between the front windshield temperature and the dew point temperature also includes a correction compensation for correcting the difference T, and the correction compensation includes at least one of ambient temperature correction, vehicle speed correction and sunlight correction. The compensation correction is corrected according to the specific application scenario of the vehicle and is not limited here.

[0067] In the specific application of this embodiment, when the vehicle is stationary, the ambient temperature correction and the sunlight correction are weightedly calculated to obtain a correction value ΔT, and the correction value ΔT is summed with the difference T to accurately determine the specific level of the fog level arrangement, and then accurately match the corresponding defog mode, so as to perform rapid defog, and ensure that the driver's line of sight is not obstructed. When the vehicle is in motion, the ambient temperature correction, the vehicle speed correction and the sunlight correction are weightedly calculated to obtain a correction value ΔT, and then accurately match the corresponding defog mode, so as to perform rapid defog, and ensure that the driver's line of sight is not obstructed. It is worth mentioning that the above is an example of a specific application scenario of the present implementation of the correction and compensation, but the present application does not limit the use of the correction compensation, and corrections are made according to specific uses in other usage scenarios.

[0068] In actual application, this embodiment can determine whether the front windshield is fogged according to the environment and usage scenario of the vehicle, and first calculate the fogging level of the front windshield of the vehicle, and then start the corresponding defog mode after receiving the defog signal.

[0090] In summary, through the technical solution proposed in this application, the fogging level of the vehicle's front windshield is first calculated, and then the corresponding defog mode can be started after receiving the defog signal. Compared with the existing defog method, the reaction time of the driver in the vehicle to start the defog system after seeing the fogging of the front windshield is eliminated, the time when the fogging of the front windshield blocks the driver's vision is shortened, and the safety performance of vehicle driving is improved. In addition, when the air conditioner is in the off mode, the vehicle control system can first calculate the fogging level of the vehicle's front windshield, and feedback it to the occupants through pop-up instructions, or pop-up instructions and voice instructions. The occupants start the air conditioner to automatic mode by clicking on the contact interaction or voice interaction on the main control screen, and match the defog mode corresponding to the fogging level; compared with the existing defog method, the reaction time of the driver in the vehicle to start the defog system after seeing the fogging of the front windshield is eliminated, the redundant time of reaction is reduced, the time when the fogging of the front windshield blocks the driver's vision is shortened, and the safety performance of vehicle driving is improved.
