[0002] Because the recirculation heating mode of car air conditioners has the advantages of rapidly raising the temperature inside the car and saving energy, most drivers choose to run the air conditioner in recirculation mode when driving in winter. However, when the air conditioner is running in recirculation mode, it easily causes fogging on the windshield. Fogging on the windshield can affect the driver's safety. To ensure safe driving, the driver needs to manually switch to external circulation heating mode to defog the windshield. However, manually switching the heating mode still poses certain risks. Summary of the Invention

[0003] In view of this, in order to solve the technical problem that the windshield fogs up when the vehicle air conditioner is running in internal circulation heating mode, requiring the driver to switch the heating mode, which affects driving safety, the present invention provides a control method, device, vehicle air conditioner and storage medium for vehicle air conditioner.

[0007] Based on the target difference and the outside humidity value, the defogging strategy corresponding to the vehicle air conditioner is determined;

[0008] The vehicle air conditioning is controlled according to the defogging strategy.

[0009] In an optional implementation, determining the defogging strategy corresponding to the vehicle air conditioning system based on the target difference and the outside humidity value includes:

[0010] When the target difference and the external humidity value meet a first preset condition, the defogging strategy is determined to be a first defogging strategy.

[0020] When the air outlet temperature value is greater than the first preset temperature value, the actual opening degree of the electronic expansion valve in the vehicle air conditioner is determined;

[0021] Based on the actual opening degree, the opening degree of the electronic expansion valve is controlled to a preset opening degree, wherein the preset opening degree is less than the actual opening degree.

[0022] In an optional implementation, the method further includes:

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] To facilitate understanding of the embodiments of the present invention, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of the present invention.

[0053] refer to Figure 1 , Figure 1 This is a flowchart illustrating a vehicle air conditioning control method provided in an embodiment of the present invention. The vehicle air conditioning control method provided in this embodiment of the present invention includes the following steps:

[0054] S101: When the vehicle air conditioner is in the first heating mode, obtain the vehicle interior temperature, vehicle exterior temperature, and vehicle exterior humidity.

[0055] In this embodiment, the vehicle air conditioner typically has a first heating mode and a second heating mode. The first heating mode is an internal circulation heating mode, and the second heating mode is an external circulation heating mode. A temperature sensor is installed inside the vehicle to collect the interior temperature value and sends the collected interior temperature value to the controller in the vehicle air conditioner for logical judgment. A temperature sensor and a humidity sensor are installed on the outside of the windshield inside the vehicle. The temperature sensor is used to collect the exterior temperature value, and the humidity sensor is used to collect the exterior humidity value. The exterior temperature value and exterior humidity value are sent to the controller in the vehicle air conditioner for logical judgment in conjunction with the interior temperature value.

[0056] S102: Determine the target difference between the interior temperature and the exterior temperature.

[0057] In this embodiment, after obtaining the interior and exterior temperature values, a target difference between the interior and exterior temperatures is calculated. Based on the target difference and the exterior humidity value, the corresponding defogging strategy for the vehicle's air conditioning system is determined. The target difference between the interior and exterior temperatures is actually the absolute value of the difference between the interior and exterior temperatures.

[0058] S103: Determine the defogging strategy corresponding to the vehicle air conditioner based on the target difference and the outside humidity value.

[0059] In this embodiment, the control unit in the vehicle air conditioner stores a pre-set control algorithm. After determining the target difference and the outside humidity value, the control algorithm performs logical judgment on the target difference and the outside humidity value to determine the corresponding defogging strategy of the vehicle air conditioner.

[0060] Specifically, in step S103, the defogging strategy corresponding to the vehicle's air conditioning system is determined based on the target difference and the outside humidity value, including:

[0061] The target preset conditions that the target difference and the external humidity value satisfy are determined from multiple preset conditions;

[0062] The defogging strategy corresponding to the target preset conditions is determined from the preset association relationship. The association relationship stores the correspondence between multiple preset conditions and defogging strategies.

[0063] The defogging strategies include: a first defogging strategy, a second defogging strategy, and a third defogging strategy. The first defogging strategy corresponds to the first preset condition among multiple preset conditions, the second defogging strategy corresponds to the second preset condition among multiple preset conditions, and the third defogging strategy corresponds to the third preset condition among multiple preset conditions.

[0064] More specifically, reference Figure 2 In step S103, based on the target difference and the outside humidity value, the corresponding defogging strategy for the vehicle's air conditioning is determined, specifically including:

[0065] S201: When the target difference and the external humidity value meet the first preset condition, the defogging strategy is determined to be the first defogging strategy.

[0066] The first preset condition includes: the target difference is within a first temperature range and the external humidity value is within a first humidity range; or,

[0067] The target difference is in the second temperature range and the outside humidity value is in the second humidity range.

[0068] In the above, the temperature value corresponding to the first temperature range is greater than the temperature value corresponding to the second temperature range, and the humidity value corresponding to the second humidity range is greater than the humidity value corresponding to the first humidity range. In this embodiment, the first temperature range, second temperature range, first humidity range, and second humidity range can be divided according to actual needs. For example, the first temperature range can be defined as a target difference T > 20℃, the second temperature range as 10℃ ≤ target difference T ≤ 20℃, the first humidity range as 40% < in-vehicle humidity < 50%, and the second humidity range as 50% ≤ in-vehicle humidity ≤ 70%. When the target difference and the external humidity value meet the first preset condition, it indicates that there is a possibility of fogging on the windshield inside the vehicle, requiring control of the vehicle's air conditioning system to defog the windshield.

[0069] S202: When the target difference and the external humidity value meet the second preset condition, the defogging strategy is determined to be the second defogging strategy.

[0070] The second preset condition includes: the target difference is within the first temperature range and the outside humidity is within the third humidity range; or,

[0071] The target difference is in the second temperature range and the outside humidity value is in the fourth humidity range.

[0072] In the above, the temperature value corresponding to the first temperature range is greater than the temperature value corresponding to the second temperature range, the humidity value corresponding to the third humidity range is greater than the humidity value corresponding to the first humidity range, and the humidity value corresponding to the fourth humidity range is greater than the humidity value corresponding to the second humidity range. In this embodiment, the first temperature range, second temperature range, third humidity range, and fourth humidity range can be set according to actual needs. For example, the first temperature range can be a target difference T > 20℃, the second temperature range can be 10℃ ≤ target difference T ≤ 20℃, the third humidity range can be an in-vehicle humidity value > 50%, and the fourth humidity range can be an in-vehicle humidity value > 70%. When the target difference and the outside humidity value meet the second preset condition, it indicates that there is a high probability of fogging on the windshield inside the vehicle, requiring control of the vehicle's air conditioning to quickly defog the windshield.

[0073] S203: When the target difference and the outside temperature value meet the third preset condition, the defogging strategy is determined to be the third defogging strategy.

[0074] The third preset condition includes: the target difference is in the third temperature range and the outside humidity value is in the fifth humidity range.

[0075] In the above description, the temperature value corresponding to the third temperature range is lower than the temperature value corresponding to the second temperature range, and the humidity value corresponding to the fifth humidity range is lower than the humidity value corresponding to the second humidity range. The third temperature range and the fifth humidity range can be set according to actual needs; this embodiment does not limit this setting. For example, the third temperature range can be a target difference T < 10℃, and the fifth humidity range can be an outside humidity value < 50%. When the target difference and the outside humidity value meet the third preset condition, it indicates that there is a very small possibility of fogging on the windshield inside the vehicle. Therefore, at this time, there is no need to control the vehicle's air conditioning; it is sufficient to continue operating the vehicle's air conditioning in its previous mode.

[0076] S104: Control the vehicle air conditioning according to the defogging strategy.

[0077] In this embodiment, after the defogging strategy is determined in step S103, the vehicle air conditioner can be controlled accordingly based on the determined defogging strategy so that when the windshield inside the vehicle fogs up, the vehicle air conditioner can be controlled to defog the windshield inside the vehicle.

[0078] Specifically, reference Figure 2 Step S104 controls the vehicle's air conditioning system according to the defogging strategy, including:

[0079] S204: When the defogging strategy is the first defogging strategy, control the vehicle air conditioning to switch from the first heating mode to the second heating mode.

[0080] In this embodiment, when the first defogging strategy is in place, there is a possibility of fogging on the windshield inside the vehicle. The vehicle's air conditioning is switched from internal circulation heating mode to external circulation heating mode to defog the windshield. During the defogging process, step S101 is executed again until the final target difference and the outside humidity value meet the third preset condition. Then, the vehicle's air conditioning is switched from external circulation heating mode to internal circulation heating mode to operate in internal circulation heating mode.

[0081] S205: When the defogging strategy is the second defogging strategy, control the vehicle air conditioning to switch from the first heating mode to the second heating mode; and,

[0082] Control the air guide plate of the first air outlet in the vehicle air conditioner to rotate towards the target position so that the air outlet of the first air outlet is directed towards the windshield inside the vehicle.

[0083] In this embodiment, the first air outlet is located on the center console inside the vehicle, and the target position can be understood as facing the windshield inside the vehicle. When the defogging strategy is the second defogging strategy, there is a high probability of fogging on the windshield inside the vehicle, requiring control of the vehicle air conditioning to quickly defog the windshield. At this time, the vehicle air conditioning is switched from internal circulation heating mode to external circulation heating mode, and the air outlet direction of the first air outlet is controlled so that the air outlet direction is facing the windshield inside the vehicle. During the defogging process, the execution of step S101 is repeated until the final target difference and the external humidity value meet the third preset condition. The vehicle air conditioning is then switched from external circulation heating mode to internal circulation heating mode to control the vehicle air conditioning to operate in internal circulation heating mode, and the air guide plate of the first air outlet in the vehicle air conditioning is controlled to rotate back to its original position (i.e., the position that has not rotated towards the target position).

[0084] S206: When the defogging strategy is the third defogging strategy, control the vehicle air conditioner to operate in the first heating mode.

[0085] In this embodiment, when the defogging strategy is the third defogging strategy, there is a very small possibility that the windshield inside the vehicle will fog up. Therefore, it is sufficient to control the vehicle air conditioner to continue operating in the first heating mode.

[0086] Through the above methods, this embodiment provides a vehicle air conditioning control method that monitors the outside temperature, inside temperature, and outside humidity values, and controls the vehicle air conditioning based on the monitored outside temperature, inside temperature, and outside humidity values ​​to achieve defogging of the windshield inside the vehicle. This eliminates the need for the driver to manually switch the heating mode, improving the safety of windshield defogging and ensuring the driver's safe driving.

[0087] In this embodiment, when the vehicle air conditioner operates in the first heating mode for an extended period of time, excessively high temperatures at the air vents at the bottom of the vehicle can cause a burning sensation in the driver's feet, affecting the driver's driving experience. Furthermore, manually adjusting the temperature can compromise driving safety. To improve both the driver's experience and safety, the temperature at the air vents at the bottom of the vehicle is monitored to control the vehicle air conditioner, thereby enhancing both the driver's experience and safety. The specific details are as follows.

[0088] refer to Figure 3 The vehicle air conditioning control method provided in this embodiment of the invention further includes the following steps:

[0089] S301: When the vehicle air conditioner is in the first heating mode, obtain the air outlet temperature value of the second air outlet in the vehicle air conditioner. The second air outlet is located at the bottom of the vehicle.

[0090] In this embodiment, a temperature sensor is installed at the second air outlet of the vehicle air conditioner. The temperature sensor is used to collect the outlet temperature value of the second air outlet of the vehicle air conditioner and send the outlet temperature value to the control unit of the vehicle air conditioner so that the control unit can make a logical judgment.

[0091] S302: Determine whether the air outlet temperature value is greater than the first preset temperature value.

[0092] In this embodiment, the first preset temperature value can be set according to actual needs, and the specific value of the first preset temperature value is not limited in this embodiment. For example, the first preset temperature value can be 50°C. When the air outlet temperature value is greater than the first preset temperature value, it indicates that the driver's feet may experience discomfort, and the air outlet temperature value of the second air outlet needs to be adjusted.

[0093] S303: When the air outlet temperature is greater than the first preset temperature value, determine the actual opening degree of the electronic expansion valve in the vehicle air conditioner.

[0094] In this embodiment, the actual opening degree of the electronic expansion valve is used to characterize the opening degree of the electronic expansion valve before any regulation is performed.

[0095] S304: Based on the actual opening degree, control the opening degree of the electronic expansion valve to the preset opening degree, where the preset opening degree is less than the actual opening degree.

[0096] In this embodiment, after determining the actual opening degree, the first difference between the outlet temperature value and the first preset temperature value can be determined. The control value corresponding to the first difference is determined from the association relationship. The association relationship stores multiple sets of correspondences between the first difference and the control value. After determining the control value, the difference between the actual opening degree and the control value is determined as the preset opening degree, and the opening degree of the electronic expansion valve is controlled to the preset opening degree.

[0097] S305: During the operation of the electronic expansion valve at a preset opening, determine whether the outlet temperature is lower than the second preset temperature value.

[0098] In this embodiment, the second preset temperature value is lower than the first preset temperature value. When the airflow from the second air outlet is reduced, to maintain the overall temperature inside the vehicle, the electronic expansion valve needs to continue operating at its actual opening when the outlet temperature is lower than the second preset temperature value. The second preset temperature can be set according to actual needs; this embodiment does not limit the specific value of the second preset temperature. For example, the second preset temperature value could be 40°C.

[0099] S306: When the outlet temperature is less than the second preset temperature, control the opening of the electronic expansion valve to the actual opening and return to execute step S301.

[0100] S307: When the outlet temperature is greater than or equal to the second preset temperature, continue to control the electronic expansion valve to operate at the preset opening.

[0101] In this embodiment, when the outlet temperature is less than or equal to the second preset temperature value, the electronic expansion valve needs to continue to operate at the preset opening to continue to reduce the air volume of the second outlet, thereby reducing the outlet temperature value of the second outlet, and returning to step S305.

[0102] S308: When the outlet temperature is less than or equal to the first preset temperature, return to execute step S301.

[0103] In this embodiment, when the air outlet temperature is less than or equal to the first preset temperature value, it indicates that the driver's feet will not feel hot. At this time, the process returns to step S301 to monitor the air outlet temperature of the second air outlet.

[0104] By using the above methods, the temperature value of the air vents at the bottom of the vehicle is monitored during the operation of the vehicle air conditioner in the first heating mode, so as to control the opening of the electronic expansion valve in the vehicle air conditioner and thus regulate the temperature of the air vents at the bottom of the vehicle. This improves the driver's driving experience and ensures the driver's driving safety by eliminating the need for manual adjustment by the driver.

[0105] In this embodiment, when the vehicle air conditioner operates in the first heating mode for an extended period of time, the air quality inside the vehicle will deteriorate. When the air quality inside the vehicle deteriorates, the driver needs to manually adjust the windows or the operating mode of the vehicle air conditioner, which cannot guarantee the driver's driving safety. Therefore, in this embodiment, when the vehicle air conditioner is operating in the first heating mode, the air quality inside the vehicle is monitored to automatically adjust the air quality inside the vehicle and ensure the driver's travel safety, as detailed below.

[0106] refer to Figure 4 The vehicle air conditioning control method provided in this embodiment further includes the following steps:

[0107] S401: Obtain the humidity value inside the vehicle when the vehicle's air conditioning is in the first heating mode.

[0108] In this embodiment, to prevent the vehicle's air conditioning from operating in the first heating mode for extended periods, which can lead to dryness due to moisture evaporation and cause discomfort and static electricity, the vehicle's air conditioning is controlled by monitoring the humidity level inside the vehicle to increase the humidity. A humidity sensor is installed inside the vehicle to collect the humidity value and send it to the control unit in the air conditioning system, allowing the control unit to make logical decisions based on the humidity level.

[0109] S402: Determine whether the humidity value inside the vehicle is less than the first preset humidity value.

[0110] In this embodiment, the first preset humidity value can be set according to actual needs, and there is no limitation on the first preset humidity value in this embodiment. For example, the first preset humidity value can be 30%. When the humidity inside the vehicle is less than the first preset humidity value, it indicates that the vehicle interior is relatively dry, and the vehicle air conditioning needs to be controlled to increase the humidity inside the vehicle.

[0111] S403: When the humidity level inside the vehicle is lower than the first preset humidity level, control the humidification device in the vehicle's air conditioning system to operate.

[0112] In this embodiment, a small humidifier is installed in the vehicle air conditioner. When the interior of the vehicle is relatively dry, the humidity inside the vehicle is increased by controlling the operation of the humidifier in the vehicle air conditioner.

[0113] S404: During the operation of the humidification device, determine whether the humidity value inside the vehicle is greater than or equal to the first preset humidity value and less than the second preset humidity value.

[0114] In this embodiment, the second preset humidity value can be set according to actual needs, and the specific value of the second preset humidity value is not limited in this embodiment. When the humidity value inside the vehicle is greater than or equal to the first preset humidity value and less than the second preset humidity value, it indicates that the humidity inside the vehicle is sufficient and there is no need to increase the humidity inside the vehicle. At this time, the humidifier in the vehicle air conditioner can be stopped from operating.

[0115] S405: When the humidity value inside the vehicle is greater than or equal to the first preset humidity value and less than the second preset humidity value, control the humidifier to stop operating.

[0116] S406: When the humidity level inside the vehicle is lower than the first preset humidity level, continue to control the humidifier in the vehicle's air conditioning system to operate.

[0117] In this embodiment, when the vehicle humidity value is still lower than the first preset humidity value, it indicates that the vehicle interior is still dry, and it is necessary to continue to control the humidifier in the vehicle air conditioner to increase the humidity inside the vehicle.

[0118] S407: If the humidity value inside the vehicle is greater than or equal to the first preset humidity value, return to execute step S401.

[0119] In this embodiment, when the humidity value inside the vehicle is greater than or equal to the first preset humidity value, it indicates that the vehicle interior is not dry. At this time, the process can return to step S401 to continue monitoring the humidity value inside the vehicle.

[0120] By using the above methods, the humidity level inside the vehicle is monitored during the operation of the vehicle's air conditioning system in the first heating mode, thereby controlling the operation of the humidifier in the air conditioning system. This achieves humidity regulation inside the vehicle, improves the air quality inside the vehicle and the driver's driving experience, and ensures the driver's driving safety.

[0121] refer to Figure 5 The vehicle air conditioning control method provided in this embodiment further includes the following steps:

[0122] S501: When the vehicle's air conditioning is in the first heating mode, obtain the carbon dioxide concentration value inside the vehicle.

[0123] In this embodiment, when the vehicle's air conditioning operates in the first heating mode for an extended period, the carbon dioxide concentration inside the vehicle continuously rises. When the carbon dioxide concentration is too high, it can cause drowsiness and affect driver safety. To ensure driver safety, the carbon dioxide concentration inside the vehicle is monitored to control the air conditioning system, thereby improving air quality and enhancing driver safety. A carbon dioxide sensor is installed inside the vehicle to collect the carbon dioxide concentration and send it to the control unit for logical decision-making.

[0124] S502: Determine whether the carbon dioxide concentration inside the vehicle is greater than the first preset concentration value.

[0125] In this embodiment, the first preset concentration value can be set according to actual needs, and the specific value of the first preset concentration value is not limited in this embodiment. For example, the first preset concentration value can be 1500 ppm. When the carbon dioxide concentration in the vehicle is greater than the first preset concentration value, it indicates that the carbon dioxide concentration in the vehicle is too high. At this time, it is necessary to control the vehicle air conditioning to reduce the carbon dioxide concentration in the vehicle, thereby improving the air quality in the vehicle and improving the driver's driving safety.

[0126] S503: When the carbon dioxide concentration inside the vehicle exceeds the first preset concentration value, control the operation of the blower in the vehicle air conditioner.

[0127] In this embodiment, the vehicle air conditioner is equipped with a blower device. When the carbon dioxide concentration inside the vehicle is too high, the blower device of the vehicle air conditioner is controlled to reduce the carbon dioxide concentration inside the vehicle.

[0128] S504: During the operation of the blower, determine whether the carbon dioxide concentration inside the vehicle is less than the second preset concentration value.

[0129] In this embodiment, the second preset concentration value can be set according to actual needs, and the specific value of the second preset concentration value is not limited in this embodiment. For example, the second preset concentration value can be 1000 ppm. When the carbon dioxide concentration in the vehicle is less than the second preset concentration value, it indicates that the carbon dioxide concentration in the vehicle has decreased, and the in-vehicle environment has been improved by controlling the operation of the blower, thus ensuring the driver's driving safety.

[0130] S505: When the carbon dioxide concentration inside the vehicle is lower than the second preset concentration value, the blower device is controlled to stop operating.

[0131] In this embodiment, when the carbon dioxide concentration inside the vehicle is less than the second preset concentration value, the blower needs to be stopped to ensure the temperature inside the vehicle.

[0132] S506: When the carbon dioxide concentration in the vehicle is greater than or equal to the second preset concentration value, continue to control the operation of the blower in the vehicle air conditioner.
