Description

Technical Field

[0001] The present invention relates to the field of terminal technology, and in particular to a vehicle control method, device, equipment and storage medium. Background Art

[0002] The dew point temperature refers to the temperature to which the gaseous water in the air needs to drop to reach saturation and condense into liquid water under fixed air pressure and water content. As the difference between the glass temperature and the dew point temperature decreases, the risk of fogging will gradually increase. In related technologies, the fogging risk is calculated by real-time monitoring of parameters such as ambient temperature, glass temperature, and dew point temperature. The corresponding air conditioning control strategy is determined based on the interval where the fogging risk occurs, and the air conditioning is then controlled to reduce the fogging risk. However, in this method, the intervals are all pre-set fixed intervals, which cannot match the complex environment of the actual vehicle use process, resulting in the selected air conditioning control strategy being inaccurate. Summary of the Invention

[0003] The purpose of the present invention is to provide a vehicle control method, device, equipment and storage medium to solve the technical problems in the prior art.

[0004] In a first aspect, an embodiment of the present application provides a vehicle control method, the method comprising:

[0005] Obtain a temperature difference and parameter information of the vehicle; the parameter information is a parameter that affects the temperature difference; the temperature difference is the difference between the glass temperature and the dew point temperature of the vehicle; obtain a first target number of first air-conditioning threshold ranges based on the parameter information; determine the first air-conditioning threshold range where the temperature difference is located from the first air-conditioning threshold range, and determine the air-conditioning control strategy corresponding to the first air-conditioning threshold range where the temperature difference is located; and control the air-conditioning of the vehicle based on the air-conditioning control strategy.

[0006] In an embodiment of the present application, the first air-conditioning threshold range of the first target number is dynamically determined by using parameter information that affects the temperature difference between the glass temperature and the dew point temperature, so that the determined first air-conditioning threshold range is more in line with the current environment of the vehicle, and the air-conditioning control strategy determined according to the temperature difference and the first air-conditioning threshold range is more matched with the current fogging risk, thereby obtaining a more accurate air-conditioning control strategy to better cope with the current fogging risk, which can avoid the waste of resources caused by adopting a high power consumption strategy under low fogging risk, and can also avoid the problem of poor defogging effect caused by adopting a strategy with low defogging ability under high fogging risk.

[0007] In some possible embodiments, the method also includes: obtaining a second target number of heating threshold ranges based on parameter information; the second target number is an integer greater than or equal to 2; determining a first heating threshold range where the temperature difference is located from the heating threshold range, and determining a heating control strategy corresponding to the first heating threshold range; and controlling the heating film of the vehicle based on the heating control strategy.

[0008] In the embodiment of the present application, the air conditioning airflow covers a limited area, and there are areas in the front windshield that are not covered by the air conditioning airflow. Therefore, during the process of using air conditioning for defrosting and defogger, the heating film in the vehicle can also be controlled to heat the windows through the heating film, so that the air conditioning and the heating film can work together to achieve uniform defogger and enhance the defrosting and defogger effect.

[0009] In some possible embodiments, obtaining a first target number of air-conditioning threshold ranges based on parameter information includes: obtaining a preset first target number of second air-conditioning threshold ranges; determining an air-conditioning target adjustment value according to the parameter information; and adjusting the first target number of second air-conditioning threshold ranges according to the air-conditioning target adjustment value to obtain a first target number of first air-conditioning threshold ranges.

[0010] In an embodiment of the present application, in the presence of a fixed second air-conditioning threshold range, it is impossible to characterize the degree of influence of the parameter information on the risk of fogging. Therefore, the second air-conditioning threshold range is adjusted according to the parameter information to obtain a first air-conditioning threshold range that is more in line with the current environment of the vehicle. Then, the air-conditioning control strategy that best fits the vehicle operating conditions can be determined based on the temperature difference and the first air-conditioning threshold range.

[0011] In some possible embodiments, before obtaining the first air-conditioning threshold range where the temperature difference is located from the first air-conditioning threshold range, it also includes: determining the air-conditioning adjustment coefficient based on the driving mode setting information of the vehicle; and adjusting the first target number of first air-conditioning threshold ranges according to the air-conditioning adjustment coefficient.

[0012] In an embodiment of the present application, in order to make the obtained first air-conditioning threshold range more suitable for the current condition of the vehicle, after obtaining the first air-conditioning threshold range, the air-conditioning adjustment coefficient is determined according to the driving mode setting information of the vehicle; thereby, the air-conditioning threshold range after adjusting the first target number of first air-conditioning threshold ranges according to the air-conditioning adjustment coefficient is more suitable for the working condition of the vehicle.

[0013] In some possible embodiments, the parameter information includes at least one of the following parameters: vehicle speed, ambient temperature, and blower speed of the vehicle.

[0014] In the embodiment of the present application, the faster the vehicle speed, the easier it is for water mist to diffuse. When other parameters remain unchanged, the risk of fogging will be reduced. The higher the ambient temperature outside the vehicle, the lower the risk of fogging. The faster the blower speed, the higher the blower air volume, and therefore the greater the impact on the airflow intensity, which can reduce the risk of fogging. Therefore, the parameters that increase the impact on the risk of fogging are used as parameter information.

[0015] In some possible embodiments, determining the air conditioning target adjustment value based on parameter information includes: determining the air conditioning adjustment value corresponding to each parameter based on each parameter in the parameter information and the influence coefficient corresponding to each parameter; calculating the sum of the air conditioning adjustment values ​​corresponding to each parameter to obtain the air conditioning target adjustment value.

[0016] In an embodiment of the present application, when there are multiple parameter information, the multiple parameter information are weighted and summed, so that the obtained air-conditioning target adjustment value can represent the impact of the multiple parameter information on the fogging risk.

[0017] In some possible embodiments, obtaining the air-conditioning control strategy corresponding to the first air-conditioning threshold range includes: determining the air-conditioning control strategy corresponding to each first air-conditioning threshold range among a first target number of first air-conditioning threshold ranges; obtaining the air-conditioning control strategy corresponding to the first air-conditioning threshold range where the temperature difference is located from the air-conditioning control strategy corresponding to each first air-conditioning threshold range.

[0018] In an embodiment of the present application, the air-conditioning control strategies corresponding to different first air-conditioning threshold ranges are not exactly the same. The air-conditioning control strategy corresponding to the first air-conditioning threshold range in which the temperature difference falls is the air-conditioning control strategy that is most suitable for the current fogging risk, further improving the defrosting and defogger effects.

[0019] In some possible embodiments, the first target number of first air-conditioning threshold ranges includes: a third air-conditioning threshold range and a fourth air-conditioning threshold range, the threshold included in the fourth air-conditioning threshold range is greater than the threshold included in the third air-conditioning threshold range, the air-conditioning control strategy corresponding to the third air-conditioning threshold range includes more air-conditioning adjustment items than the air-conditioning control strategy corresponding to the fourth air-conditioning threshold range, and the air-conditioning control strategy corresponding to the third air-conditioning threshold range includes the air-conditioning adjustment items in the air-conditioning control strategy corresponding to the fourth air-conditioning threshold range.

[0020] In an embodiment of the present application, the air-conditioning threshold range with a larger air-conditioning threshold value includes fewer air-conditioning adjustment items, and the air-conditioning threshold range with a smaller air-conditioning threshold value includes more air-conditioning adjustment items, and the air-conditioning adjustment items corresponding to the air-conditioning threshold range with a small threshold value include the air-conditioning adjustment items corresponding to the air-conditioning threshold range with a large threshold value. The smaller the temperature difference, the greater the risk of fogging. Therefore, more air-conditioning adjustment items are set in the air-conditioning threshold range with a large air-conditioning threshold value, and then more air-conditioning adjustment items can be used for defrosting and defogger when the risk of fogging is high to ensure the defrosting effect.

[0021] In some possible embodiments, the first target number is an integer greater than or equal to 3, and the first target number of first air-conditioning threshold ranges includes: a fifth air-conditioning threshold range, a sixth air-conditioning threshold range, and a seventh air-conditioning threshold range; the method also includes: if the air-conditioning of the vehicle is controlled based on the air-conditioning control strategy corresponding to the fifth air-conditioning threshold range in the first air-conditioning threshold range, and it is detected that the temperature difference enters the seventh air-conditioning threshold range, the air-conditioning control strategy corresponding to the sixth air-conditioning threshold range is adopted to control the air-conditioning of the vehicle; wherein, the threshold included in the seventh air-conditioning threshold range is greater than the threshold included in the sixth air-conditioning threshold range, and the threshold included in the sixth air-conditioning threshold range is greater than the threshold included in the fifth air-conditioning threshold range.

[0022] In an embodiment of the present application, as the vehicle air conditioning is controlled, the risk of fogging in the vehicle gradually decreases, and the temperature difference also increases. In the process of increasing the temperature difference, it may jump repeatedly in multiple first air conditioning threshold ranges. Therefore, after the temperature difference increases, the air conditioning will not be directly controlled according to the air conditioning control strategy corresponding to the first air conditioning threshold range where the increased temperature difference is located, avoiding the problem of poor user experience caused by frequent adjustments to the vehicle's air conditioning.

[0023] In some possible embodiments, obtaining a second target number of first heating threshold ranges based on parameter information includes: obtaining a preset second target number of second heating threshold ranges; determining a heating target adjustment value according to the parameter information; and adjusting the second target number of second heating threshold ranges according to the heating target adjustment value to obtain a second target number of first heating threshold ranges.

[0024] In the embodiment of the present application, the second heating threshold range is fixed and cannot characterize the degree of influence of the parameter information on the risk of fogging. Therefore, the second heating threshold range is adjusted according to the parameter information to obtain the first heating threshold range that is more in line with the current environment of the vehicle. Then, the heating control strategy that best fits the vehicle operating conditions can be determined based on the temperature difference and the first heating threshold range.

[0025] In some possible embodiments, before obtaining the first heating threshold range where the temperature difference is located from the heating threshold range, it also includes: determining the vehicle's driving mode setting information to determine a heating adjustment coefficient; and adjusting a second target number of first heating threshold ranges according to the heating adjustment coefficient.

[0026] In an embodiment of the present application, in order to make the obtained first heating threshold range more suitable for the current vehicle condition, after obtaining the first heating threshold range, the heating adjustment coefficient is determined according to the vehicle's driving mode setting information; thereby, the heating threshold range after adjusting the first target number of first heating threshold ranges according to the heating adjustment coefficient is more suitable for the vehicle's operating condition.

[0027] In some possible embodiments, determining the heating target adjustment value based on parameter information includes: determining the heating adjustment value corresponding to each parameter based on each parameter in the parameter information and the influence coefficient corresponding to each parameter; calculating the sum of the heating adjustment values ​​corresponding to each parameter to obtain the heating target adjustment value.

[0028] In an embodiment of the present application, when there are multiple parameter information, the multiple parameter information are weighted and summed, so that the obtained heating target adjustment value can represent the impact of the multiple parameter information on the fogging risk.

[0029] In some possible embodiments, obtaining the heating control strategy corresponding to the first heating threshold range includes: determining the heating control strategy corresponding to each first heating threshold range in a second target number of first heating threshold ranges; and obtaining the heating control strategy corresponding to the first heating threshold range where the temperature difference is located from the heating control strategy corresponding to each first heating threshold range.

[0030] In an embodiment of the present application, the heating power and target temperature in the heating control strategy corresponding to different first heating threshold ranges are different. The heating control strategy corresponding to the first heating threshold range in which the temperature difference falls is the heating control strategy that is most suitable for the current fogging risk, further improving the defrosting and defogger effect.

[0031] In some possible embodiments, a heating control strategy corresponding to the first heating threshold range where the temperature difference is located is obtained from the heating control strategy corresponding to each first heating threshold range, including: obtaining the heating power and the target heating temperature based on the first heating threshold range where the temperature difference is located; and controlling the heating film to heat to the target heating temperature based on the heating power.

[0032] In an embodiment of the present application, the heating power and target temperature in the heating control strategy corresponding to different first heating threshold ranges are different. The heating control strategy corresponding to the first heating threshold range in which the temperature difference falls is the heating control strategy that is most suitable for the current fogging risk, further improving the defrosting and defogger effect.

[0033] In some possible embodiments, the heating film is controlled to be heated to a target heating temperature according to the heating power, including: obtaining a heating time according to a first target heating threshold range in which the temperature difference is located; if the heating time of the heating film controlled according to the heating power reaches the heating time, and the heating film has not yet been heated to the target heating temperature, the heating film is controlled to stop heating.

[0034] In the embodiment of the present application, if the target heating temperature is not reached after the heating time has expired, it may indicate that the current ambient temperature of the vehicle is low and the defrosting effect of continuing to heat the heating film is poor, so heating can be stopped to save power consumption.

[0035] In some possible embodiments, the second target number of first heating threshold ranges includes: a third heating threshold range, a fourth heating threshold range, and a fifth heating threshold range; the method also includes: if the heating film of the vehicle is controlled based on the heating control strategy corresponding to the third heating threshold range in the first heating threshold range, and it is detected that the temperature difference enters the fifth heating threshold range, the heating control strategy corresponding to the fourth heating threshold range is adopted to control the heating film of the vehicle; wherein, the heating power and target heating temperature corresponding to the third heating threshold range are greater than the heating power and target heating temperature corresponding to the fourth heating threshold range; the heating power and target heating temperature corresponding to the fourth heating threshold range are greater than the heating power and target heating temperature corresponding to the fifth heating threshold range.

[0036] In an embodiment of the present application, as the vehicle heating is controlled, the risk of fogging of the vehicle gradually decreases, and the temperature difference also increases accordingly. In the process of increasing the temperature difference, it may jump repeatedly in multiple first heating threshold ranges. Therefore, after the temperature difference increases, the heating will not be directly controlled according to the heating control strategy corresponding to the first heating threshold range where the increased temperature difference is located, avoiding the problem of poor user experience caused by frequent adjustments to the vehicle's heating film.

[0037] In some possible embodiments, the first target number is the same as the second target number, the first target number of first air-conditioning threshold ranges corresponds one-to-one to the second target number of heating threshold ranges, and the range length of the first air-conditioning threshold range is greater than the range length of the heating threshold range corresponding to the first air-conditioning threshold range.

[0038] In an embodiment of the present application, since increasing the blower air volume and increasing the window blowing ratio will have a greater impact on the user's physical sensation, before entering the first air-conditioning threshold range corresponding to increasing the blower air volume and increasing the window blowing ratio, a heating film can be used to heat the car windows, thereby improving the user experience while ensuring the defrosting effect.

[0039] In some possible embodiments, the first target number of first air-conditioning threshold ranges includes: a third air-conditioning threshold range, a fourth air-conditioning threshold range; the air-conditioning control strategy corresponding to the third air-conditioning threshold range does not include switching the compressor speed, and the air-conditioning control strategy corresponding to the fourth air-conditioning threshold range includes switching the compressor speed; the third air-conditioning threshold range is adjacent to the fourth air-conditioning threshold range; the first endpoint value is equal to the second endpoint value, the first endpoint value is the common endpoint value between the third air-conditioning threshold range and the fourth air-conditioning threshold range, and the second endpoint value is the common endpoint value between the heating threshold range corresponding to the third air-conditioning threshold range and the heating threshold range corresponding to the fourth air-conditioning threshold range.

[0040] In an embodiment of the present application, since increasing the compressor speed will place higher requirements on the vehicle's power consumption, increase noise, and aggravate the wear of components, when using the air-conditioning control strategy corresponding to the third air-conditioning threshold range to perform the defrosting and defogger process, in order to avoid the temperature difference from entering the fourth air-conditioning threshold range, the heating control strategy corresponding to the heating threshold range corresponding to the third air-conditioning threshold range can be used at the same time to control the heating film, so that the heating film and the air-conditioning work together to perform defrosting and defogger.

The first target number of first air-conditioning threshold ranges includes: a third air-conditioning threshold range, a fourth air-conditioning threshold range; the air-conditioning control strategy corresponding to the third air-conditioning threshold range does not include switching the compressor speed, and the air-conditioning control strategy corresponding to the fourth air-conditioning threshold range includes switching the compressor speed; the third air-conditioning threshold range is adjacent to the fourth air-conditioning threshold range; the first endpoint value is greater than the second endpoint value, the first endpoint value is the common endpoint value between the third air-conditioning threshold range and the fourth air-conditioning threshold range, and the second endpoint value is the common endpoint value between the heating threshold range corresponding to the third air-conditioning threshold range and the heating threshold range corresponding to the fourth air-conditioning threshold range.

[0042] In an embodiment of the present application, before adopting the air conditioning control strategy corresponding to increasing the compressor speed with higher power consumption, a heating film control strategy with uniform heating, low power consumption and no user perception is first adopted to control the heating film.

[0043] In some possible embodiments, the third endpoint value is greater than the fourth endpoint value, the third endpoint value is the endpoint value in the third air-conditioning threshold range except the first endpoint value, and the fourth endpoint value is the endpoint value in the heating threshold range corresponding to the third air-conditioning threshold range except the second endpoint value.

[0101] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0102] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0103] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0104] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0105] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0106] Dew point temperature refers to the temperature at which the gaseous water in the air reaches saturation and condenses into liquid water under fixed air pressure and water content. As the difference between the glass temperature and the dew point temperature decreases, the risk of fogging gradually increases. Related technologies calculate the fogging risk by real-time monitoring of parameters such as ambient temperature, glass temperature, and dew point temperature. The corresponding air conditioning control strategy is determined based on the fixed range of fogging risk, such as Figure 1 As shown, to Figure 2The front windshield shown in the figure is blown to increase the glass temperature or lower the dew point temperature to reduce the risk of fogging. However, in this method, the intervals are pre-set and cannot be adjusted in real time according to the environment, resulting in inaccurate air conditioning control strategies.

[0107] To address the above-mentioned issues, embodiments of the present application provide a vehicle control method, apparatus, device, and storage medium for resolving the above-mentioned issues. The inventive concept of the present application can be summarized as follows: obtaining a vehicle temperature difference and parameter information; the parameter information is a parameter that affects the temperature difference; the temperature difference is the difference between the vehicle's glass temperature and the dew point temperature; obtaining a first target number of first air conditioning threshold ranges based on the parameter information; obtaining the first air conditioning threshold range within which the temperature difference lies from the first air conditioning threshold range, and obtaining an air conditioning control strategy corresponding to the first air conditioning threshold range within which the temperature difference lies; and controlling the vehicle's air conditioning based on the air conditioning control strategy.

[0108] In an embodiment of the present application, the first air-conditioning threshold range of the first target number is dynamically determined by using parameter information that affects the temperature difference between the glass temperature and the dew point temperature, so that the determined first air-conditioning threshold range is more in line with the current environment of the vehicle, and the air-conditioning control strategy determined according to the temperature difference and the first air-conditioning threshold range is more matched with the current fogging risk, thereby obtaining a more accurate air-conditioning control strategy to better cope with the current fogging risk, which can avoid the waste of resources caused by adopting a high power consumption strategy under low fogging risk, and can also avoid the problem of poor defogging effect caused by adopting a strategy with low defogging ability under high fogging risk.

[0109] For ease of understanding, a vehicle control method provided by an embodiment of the present application is described in detail below with reference to the accompanying drawings:

[0110] like Figure 3 FIG. 1 is a schematic diagram of the overall process of a vehicle control method provided by an embodiment of the present application, wherein:

[0111] In step 301: the temperature difference and parameter information of the vehicle are obtained; the parameter information is the parameter that affects the temperature difference; the temperature difference is the difference between the glass temperature and the dew point temperature of the vehicle.

[0112] In the embodiments of the present application, the vehicle's window temperature can be obtained using a temperature sensor installed on the vehicle window, and the dew point temperature in the vehicle can be obtained using a device such as a dry-bulb thermometer or a dew point meter, thereby obtaining a temperature difference. Parameters that may affect the temperature difference can be used as parameter information in this application, including but not limited to vehicle speed, external ambient temperature, blower speed, and external air humidity.

[0113] In step 302: a first target number of first air-conditioning threshold ranges are obtained based on the parameter information.

[0114] In an embodiment of the present application, considering the different effects of different air-conditioning controls on the user's physical sensations and the different power consumption requirements for the vehicle, at least three first air-conditioning threshold ranges need to be set, so the first target number is an integer greater than or equal to 3.

[0115] In some possible embodiments, the first air conditioning threshold range is obtained according to the parameter information, which can be specifically implemented as follows: Figure 4A The steps shown, where:

[0116] In step 401: a preset first target number of second air-conditioning threshold ranges is obtained.

[0117] In an embodiment of the present application, the first target number is an integer greater than or equal to 3, so there are at least three pre-set second air-conditioning threshold ranges. Since the second air-conditioning threshold range is fixed, it is impossible to characterize the degree of influence of the parameter information on the fogging risk. Therefore, it is necessary to adjust the second air-conditioning threshold range according to the parameter information to obtain a first air-conditioning threshold range that is more in line with the current environment of the vehicle.

[0118] It is understandable that in the presence of a fixed second air conditioning threshold range, Figure 4A The method shown is used to adjust the second air conditioning threshold range. If the second air conditioning threshold range does not exist, the preset value can be directly used as the second air conditioning threshold range. Figure 4A The method shown directly determines the first air conditioning threshold range.

[0119] In step 402: an air conditioning target adjustment value is determined according to the parameter information.

[0120] In the embodiment of the present application, the parameter information includes but is not limited to: the vehicle speed, the ambient temperature outside the vehicle, and the blower speed of the vehicle.

[0121] In some possible embodiments, the air conditioning target adjustment value is determined based on the parameter information, which can be specifically implemented as follows: the air conditioning adjustment value corresponding to each parameter is determined based on each parameter in the parameter information and the influence coefficient corresponding to each parameter; the sum of the air conditioning adjustment values ​​corresponding to each parameter is calculated to obtain the air conditioning target adjustment value.

[0122] Among them, the influence coefficient represents the degree of influence of different parameter information on the air conditioner; in an embodiment of the present application, when the air conditioner target adjustment value is jointly determined based on multiple parameter information, the air conditioner target adjustment value is obtained by weighted summing the multiple parameters, and when the air conditioner target adjustment value is determined based on a single parameter information, the air conditioner adjustment value obtained based on the parameter is directly used as the air conditioner target adjustment value.

[0123] For example, if the parameter information includes vehicle speed, ambient temperature, and blower speed, the influence coefficient corresponding to vehicle speed is a, the influence coefficient corresponding to ambient temperature is b, and the influence coefficient corresponding to blower speed is c, then the air conditioning target adjustment value = a = vehicle speed + b = ambient temperature + c = blower speed.

[0124] The parameters include: vehicle speed and ambient temperature. The influence coefficient corresponding to vehicle speed is a, and the influence coefficient corresponding to ambient temperature is b. The air conditioning target adjustment value = a vehicle speed + b ambient temperature;

[0125] The parameters include: blower speed, the influence coefficient corresponding to the blower speed is c, and the air conditioning target adjustment value = c blower speed.

[0126] It should be noted that the faster the vehicle speed, the easier it is for the water mist to diffuse. When other parameters remain unchanged, the risk of fogging will be reduced. Therefore, the influence coefficient a corresponding to the vehicle speed is a positive number; when other parameters remain unchanged, the higher the ambient temperature outside the vehicle, the lower the risk of fogging. Therefore, the influence coefficient b corresponding to the ambient temperature is a positive number; when other parameters remain unchanged, the faster the blower speed, the higher the blower air volume, and therefore the greater the impact on the airflow intensity, which can reduce the risk of fogging. Therefore, the influence coefficient c corresponding to the blower speed is a negative number.

[0127] In step 403 : the first target number of second air-conditioning threshold ranges are adjusted according to the air-conditioning target adjustment value to obtain the first target number of first air-conditioning threshold ranges.

[0128] In some possible embodiments, the specific numerical values ​​of each second air-conditioning threshold range are different, so after adjusting different second air-conditioning threshold ranges using the same air-conditioning adjustment value, different first air-conditioning threshold ranges are obtained.

[0129] For example, if there are three second air-conditioning threshold ranges, namely [d1, d2], (d2, d3], and (d3, d4], then there are four second air-conditioning thresholds, namely d1, d2, d3, and d4. The air-conditioning target adjustment value is summed with d1 to obtain A; the air-conditioning target adjustment value is summed with d2 to obtain B; the air-conditioning target adjustment value is summed with d3 to obtain C; the air-conditioning target adjustment value is summed with d4 to obtain D; the obtained first air-conditioning thresholds are A, B, C, and D, and the three first air-conditioning threshold ranges obtained based on the first air-conditioning threshold are respectively: [A, B], (B, C], and (C, D].

[0130] In other possible embodiments, in order to make the obtained first air-conditioning threshold range more suitable for the current condition of the vehicle, after obtaining the first air-conditioning threshold range, the air-conditioning adjustment coefficient can be determined based on the driving mode of the vehicle; and the first target number of first air-conditioning threshold ranges can be adjusted according to the air-conditioning adjustment coefficient.

[0131] Among them, different driving modes correspond to different air-conditioning adjustment coefficients, and the driving modes include but are not limited to: energy-saving mode of different gears, standard mode, sports mode, comfort mode, etc.; the air-conditioning adjustment coefficient user dynamically adjusts the first air-conditioning threshold range to make the adjusted first air-conditioning threshold range more in line with the current driving mode of the vehicle.

[0132] For example: the user sets the vehicle to energy-saving mode 1, and the air-conditioning adjustment coefficient corresponding to energy-saving mode 1 is k1. According to the vehicle parameter information, the air-conditioning thresholds corresponding to the first air-conditioning threshold range of the vehicle are A, B, C, and D. The air-conditioning adjustment coefficient k1 is used to adjust the air-conditioning threshold A, and the adjusted air-conditioning threshold is k1A; the air-conditioning adjustment coefficient k1 is used to adjust the air-conditioning threshold B, and the adjusted air-conditioning threshold is k1B; the air-conditioning adjustment coefficient k1 is used to adjust the air-conditioning threshold C, and the adjusted air-conditioning threshold is k1C; the air-conditioning adjustment coefficient k1 is used to adjust the air-conditioning threshold D, and the adjusted air-conditioning threshold is k1D; and the adjusted first air-conditioning threshold ranges can be obtained as follows: [k1A, k1B], (k1B, k1C], (k1C, k1D].

[0133] Step 303: Obtain the first air-conditioning threshold range where the temperature difference is located from the first air-conditioning threshold range, and obtain the air-conditioning control strategy corresponding to the first air-conditioning threshold range where the temperature difference is located.

[0134] In an embodiment of the present application, the air-conditioning control strategies corresponding to different first air-conditioning threshold ranges are not exactly the same. The air-conditioning control strategy corresponding to the first air-conditioning threshold range in which the temperature difference falls is the air-conditioning control strategy corresponding to the current fogging risk, that is: the air-conditioning control strategy corresponding to the first air-conditioning threshold range in which the temperature difference falls is obtained from the air-conditioning control strategy corresponding to each first air-conditioning threshold range.

[0135] In some possible embodiments, the first target number of first air-conditioning threshold ranges includes: a third air-conditioning threshold range and a fourth air-conditioning threshold range, the threshold included in the fourth air-conditioning threshold range is greater than the threshold included in the third air-conditioning threshold range, the air-conditioning control strategy corresponding to the third air-conditioning threshold range includes more air-conditioning adjustment items than the air-conditioning control strategy corresponding to the fourth air-conditioning threshold range, and the air-conditioning control strategy corresponding to the third air-conditioning threshold range includes the air-conditioning adjustment items in the air-conditioning control strategy corresponding to the fourth air-conditioning threshold range.

[0136] That is, in an embodiment of the present application, the air-conditioning threshold range with a larger air-conditioning threshold includes fewer air-conditioning adjustment items, and the air-conditioning threshold range with a smaller air-conditioning threshold includes more air-conditioning adjustment items, and the air-conditioning adjustment items corresponding to the air-conditioning threshold range with a smaller threshold include the air-conditioning adjustment items corresponding to the air-conditioning threshold range with a larger threshold.

[0137] For example: Figure 4B As shown, the air-conditioning thresholds include: A, B, C, D, where A is greater than B, B is greater than C, and C is greater than D. The first air-conditioning threshold range formed based on the air-conditioning threshold includes: [A, B], (B, C], (C, D], where the air-conditioning adjustment items included in [A, B] are: increasing the external circulation ratio; the air-conditioning adjustment items corresponding to (B, C] are: increasing the external circulation ratio and increasing the compressor speed; the air-conditioning adjustment items corresponding to (C, D] are: increasing the external circulation ratio, increasing the compressor speed, increasing the blower speed, and increasing the window blowing ratio.

[0138] It can be seen that the air-conditioning threshold value included in the first air-conditioning threshold range (C, D] is smaller than the threshold value included in (B, C], that is, the upper limit value of (C, D] is C, and the lower limit value is D, the upper limit value of (B, C] is B, and the lower limit value is C, the air-conditioning adjustment items included in the first air-conditioning threshold range (C, D] are more than the air-conditioning adjustment items included in [B, C], and the first air-conditioning threshold range (C, D] includes the air-conditioning adjustment items included in (B, C]; the relationship between the first air-conditioning threshold range (B, C] and [A, B] is the same as the relationship between (C, D] and (B, C], which will not be repeated here.

[0139] In step 304 : the air conditioning of the vehicle is controlled based on the air conditioning control strategy.

[0140] In an embodiment of the present application, after obtaining the air conditioning control strategy, the air conditioning control strategy is used to control the air conditioning in the vehicle to increase the difference between the glass temperature and the dew point temperature, thereby reducing the risk of fogging.

[0141] In other possible embodiments, as the vehicle air conditioning is controlled, the risk of fogging of the vehicle gradually decreases, and the temperature difference value also increases accordingly. During the process of increasing the temperature difference value, it may repeatedly jump between multiple first air conditioning threshold ranges. In order to avoid the problem of poor user experience caused by frequent adjustment of the vehicle air conditioning, it can be implemented as follows: when the vehicle air conditioning is controlled based on the air conditioning control strategy corresponding to the fifth air conditioning threshold range in the first air conditioning threshold range, if it is detected that the temperature difference value enters the seventh air conditioning threshold range, the vehicle air conditioning is controlled using the air conditioning control strategy corresponding to the sixth air conditioning threshold range;

[0142] Among them, the first target number of first air-conditioning threshold ranges includes: the fifth air-conditioning threshold range, the sixth air-conditioning threshold range, and the seventh air-conditioning threshold range; the threshold included in the seventh air-conditioning threshold range is greater than the threshold included in the sixth air-conditioning threshold range, and the threshold included in the sixth air-conditioning threshold range is greater than the threshold included in the fifth air-conditioning threshold range.

[0143] That is, in the embodiment of the present application, after the temperature difference increases, the air conditioner is not directly controlled according to the air conditioner control strategy corresponding to the first air conditioner threshold range where the increased temperature difference is located.

[0144] For example, the first air conditioning threshold range includes: [A, B], (B, C], (C, D], and the current temperature difference is in (C, D]. The air conditioning control strategy corresponding to (C, D] is used to control the air conditioning in the vehicle, that is, the air conditioning is controlled to increase the external circulation ratio, increase the compressor speed, increase the blower speed, and increase the window blowing ratio; as the air conditioning is running, the temperature difference falls into (B, C], and the air conditioning control strategy is not changed at this time; as the air conditioning is running, the temperature difference falls into [A, B], and the air conditioning control strategy corresponding to (B, C] is used to control the air conditioning, that is, the air conditioning is controlled to increase the external circulation ratio and increase the compressor speed.

[0145] As the air conditioner continues to run, the temperature difference gradually becomes greater than A, and the duration of the temperature difference exceeding A is longer than the first air conditioner preset duration. At this time, the air conditioner control strategy corresponding to [A, B] can be used to control the air conditioner, that is, to control the air conditioner to increase the external circulation ratio;

[0146] At this time, the air conditioner continues to run, the temperature difference continues to be greater than A, and the time it is greater than A is greater than the second air conditioner preset time, and the air conditioner can be stopped from being controlled.

[0147] It can be seen from this that in the fallback process of air conditioning control, if the first air conditioning threshold range greater than the current air conditioning threshold range is less than 2, it can be determined whether the air conditioning control needs to be rolled back based on the time when the temperature difference is greater than the maximum air conditioning threshold.

[0148] In some possible embodiments, such as Figure 5 As shown in the figure, the air conditioning airflow covers a limited area. There are areas in the front windshield that are not covered by the air conditioning airflow, such as corners and areas near the A-pillars on both sides, which will affect the user's field of vision. In order to achieve uniform defogging, Figure 6 As shown, some vehicles are equipped with a heating film in the front windshield. Based on this, while controlling the air conditioning in the vehicle, the following can also be used: Figure 7 The steps shown are used to control the heating film in the vehicle, so that the air conditioner and the heating film work together to enhance the defrosting and defogging effects. Specifically:

[0149] In step 701: a second target number of heating threshold ranges is obtained based on the parameter information; the second target number is an integer greater than or equal to 2.

[0150] In the embodiment of the present application, different heating threshold ranges are set to control the heating film for different durations and powers. Therefore, it is necessary to determine the heating threshold range that best matches the current vehicle condition based on parameter information.

[0151] In some possible embodiments, obtaining a second target number of first heating threshold ranges based on the parameter information may be specifically implemented as follows: Figure 8 The steps shown, where:

[0152] In step 801 : obtaining a preset second target number of second heating threshold ranges.

[0153] In an embodiment of the present application, the second target number is an integer greater than or equal to 2, so there are at least two pre-set second heating threshold ranges. Since the second heating threshold range is fixed, it is impossible to characterize the degree of influence of the parameter information on the fogging risk. Therefore, it is necessary to adjust the second heating threshold range according to the parameter information to obtain a first heating threshold range that is more in line with the current environment of the vehicle.

[0154] In step 802: a heating target adjustment value is determined according to the parameter information.

[0155] In some possible embodiments, determining the heating target adjustment value can be specifically implemented as follows: determining the heating adjustment value corresponding to each parameter based on each parameter in the parameter information and the influence coefficient corresponding to each parameter; calculating the sum of the heating adjustment values ​​corresponding to each parameter to obtain the heating target adjustment value.

[0156] Among them, the influence coefficient represents the degree of influence of different parameter information on the air conditioner; in an embodiment of the present application, when the heating target adjustment value is jointly determined based on multiple parameter information, the heating target adjustment value is obtained by weighted summing the multiple parameters, and when the heating target adjustment value is determined based on a single parameter information, the heating adjustment value obtained based on the parameter is directly used as the heating target adjustment value.

[0157] For example, if the parameter information includes vehicle speed, ambient temperature, and blower speed, the influence coefficient corresponding to vehicle speed is a, the influence coefficient corresponding to ambient temperature is b, and the influence coefficient corresponding to blower speed is c, then the heating target adjustment value = a = vehicle speed + b = ambient temperature + c = blower speed;

[0158] The parameters include: vehicle speed and ambient temperature. The influence coefficient corresponding to vehicle speed is a, and the influence coefficient corresponding to ambient temperature is b. The heating target adjustment value = a vehicle speed + b ambient temperature;

[0159] The parameters include: blower speed, the influence coefficient corresponding to the blower speed is c, and the heating target adjustment value = c blower speed.

[0160] In step 803 : a second target number of second heating threshold ranges are adjusted according to the heating target adjustment value to obtain a second target number of first heating threshold ranges.

[0161] In some possible embodiments, the specific numerical values ​​of each second heating threshold range are different. Therefore, after adjusting different second heating threshold ranges using the same heating adjustment value, different first heating threshold ranges are obtained.

[0162] For example, if there are three second heating threshold ranges, namely [t1, t2], (t2, t3], and (t3, t4], then there are four second heating thresholds, namely t1, t2, t3, and t4. The heating target adjustment value is summed with t1 to obtain X; the heating target adjustment value is summed with t2 to obtain Y; the heating target adjustment value is summed with t3 to obtain Z; the heating target adjustment value is summed with t4 to obtain R; the obtained first heating thresholds are X, Y, Z, and R, and the three first heating threshold ranges obtained based on the first heating thresholds are respectively: [X, Y], (Y, Z], and (Z, R].

[0163] In other possible embodiments, in order to make the obtained first heating threshold range more suitable for the current condition of the vehicle, after obtaining the first heating threshold range, the heating adjustment coefficient can be determined according to the vehicle's driving mode setting information; and the second target number of first heating threshold ranges can be adjusted according to the heating adjustment coefficient.

[0164] Among them, different driving mode setting information corresponds to different heating adjustment coefficients, and the driving modes include but are not limited to: energy-saving mode, standard mode, sports mode, comfort mode, etc. of different gears; the heating adjustment coefficient user dynamically adjusts the first heating threshold range to make the adjusted first heating threshold range more in line with the current driving mode of the vehicle.

[0165] For example: the user sets the vehicle to energy-saving mode 1, and the heating adjustment coefficient corresponding to energy-saving mode 1 is k2. According to the vehicle parameter information, the heating thresholds corresponding to the first heating threshold range of the vehicle are X, Y, Z, and R. The heating adjustment coefficient k2 is used to adjust the heating threshold X, and the adjusted heating threshold is k2X; the heating adjustment coefficient k2 is used to adjust the heating threshold Y, and the adjusted heating threshold is k2Y; the heating adjustment coefficient k2 is used to adjust the heating threshold Z, and the adjusted heating threshold is k2Z; the heating adjustment coefficient k2 is used to adjust the heating threshold R, and the adjusted heating threshold is k2R; and the adjusted first heating threshold ranges can be obtained as: [k2Z, k2Y], (k2Y, k2Z], (k2Z, k2R].

[0166] In step 702 : a first heating threshold range in which the temperature difference is located is obtained from the heating threshold range, and a heating control strategy corresponding to the first heating threshold range is obtained.

[0167] In an embodiment of the present application, the heating power and target heating temperature in the heating control strategies corresponding to different first heating threshold ranges are different. The heating control strategy corresponding to the first heating threshold range in which the temperature difference falls is the heating control strategy corresponding to the current fogging risk, that is: the heating control strategy corresponding to the first heating threshold range in which the temperature difference falls is obtained from the heating control strategy corresponding to each first heating threshold range.

[0168] For example, the heating thresholds include X, Y, Z, and R, where X is greater than Y, Y is greater than Z, and Z is greater than R. The first heating threshold range based on the heating thresholds includes [X, Y], (Y, Z], and (Z, R], where the heating power corresponding to [X, Y] is P1 and the target heating temperature is T1; the heating power corresponding to (Y, Z] is P2 and the target heating temperature is T2; the heating power corresponding to (Z, R] is P3 and the target heating temperature is T3; where P1 is less than P2, P2 is less than P3, T1 is less than T2, and T2 is less than T3.

[0169] In step 703: the heating film of the vehicle is controlled based on the heating control strategy.

[0170] That is, in the embodiment of the present application, the heating power and the target heating temperature are obtained according to the first heating threshold range where the temperature difference is located; and the heating film is controlled to be heated to the target heating temperature according to the heating power.

[0171] In other possible embodiments, if the vehicle is in a relatively cold environment, heating the heating film for a long time will not enable the heating film to reach the target temperature. At this time, in order to save energy, there is no need to heat the heating film for a long time. Specifically, it can be implemented as follows: according to the first target heating threshold range where the temperature difference is located, the heating time is obtained; if the heating time of the heating film controlled according to the heating power reaches the heating time, and the heating film has not yet been heated to the target heating temperature, the heating film is controlled to stop heating.

[0172] That is, in the embodiment of the present application, each first target heating threshold range is set with a corresponding heating time, and the heating film is heated according to the heating time corresponding to each first target heating threshold range. When the heating time of the heating film reaches the heating time corresponding to the first target heating threshold range, if the heating film still does not reach the target heating temperature, there is no need to continue heating the heating film.

[0173] In other possible embodiments, as the vehicle heating is controlled, the risk of fogging of the vehicle gradually decreases, and the temperature difference also increases. In the process of increasing the temperature difference, it may jump repeatedly in multiple first heating threshold ranges. In order to avoid the problem of poor user experience caused by frequent adjustments to the vehicle heating, it can be implemented: if the heating film of the vehicle is controlled based on the heating control strategy corresponding to the third heating threshold range in the first heating threshold range, it is detected that the temperature difference enters the fifth heating threshold range, then the heating control strategy corresponding to the fourth heating threshold range is used to control the heating film of the vehicle.

[0174] Among them, the second target number of first heating threshold ranges includes: the third heating threshold range, the fourth heating threshold range, and the fifth heating threshold range; the heating power and target heating temperature corresponding to the third heating threshold range are greater than the heating power and target heating temperature corresponding to the fourth heating threshold range; the heating power and target heating temperature corresponding to the fourth heating threshold range are greater than the heating power and target heating temperature corresponding to the fifth heating threshold range.

[0175] That is, in the embodiment of the present application, after the temperature difference increases, the heating is not directly controlled according to the heating control strategy corresponding to the first heating threshold range where the increased temperature difference is located.

[0176] For example: the first heating threshold range includes: [X, Y], (Y, Z], (Z, R], the current temperature difference is in (Z, R], and the heating control strategy corresponding to (Z, R] is adopted to control the heating in the vehicle, that is, the heating power adopted is P3, and the target heating temperature is T3; as the heating film is heated, the temperature difference falls into (Y, Z], and the heating control strategy is not changed at this time; as the heating film is heated, the temperature difference falls into [X, Y], and the heating control strategy corresponding to (Y, Z] is adopted to control the heating, that is, the heating power adopted is P2, and the target heating temperature is T2.

[0177] As the heating film continues to heat, the temperature difference gradually becomes greater than X, and the time it is greater than X is longer than the first heating preset time. At this time, the heating control strategy corresponding to [X, Y] can be used to control the heating, that is, the heating power is P1 and the target heating temperature is T1; at this time, the heating film continues to heat, the temperature difference continues to be greater than X, and the time it is greater than X is longer than the second heating preset time. At this time, the control of the heating film can be stopped.

[0178] It can be seen from this that in the process of falling back on the control of the heating film, if the first heating threshold range greater than the current heating threshold range is less than 2, it can be determined whether the control of the heating film needs to be fallen back based on the time when the temperature difference is greater than the maximum heating threshold.

[0179] In some possible embodiments, considering that increasing the external circulation ratio by controlling the air conditioner is imperceptible to the user and the energy consumption of the air conditioner is relatively low, compared with increasing the external circulation ratio by the air conditioner, using a heating film to heat the front windshield requires higher vehicle energy consumption. Therefore, when there is a risk of fogging and frosting, it is preferred to control the air conditioner to increase the external circulation ratio. This can ensure the defogging effect while reducing the power consumption demand of the entire vehicle. Therefore, the upper limit value of the largest air-conditioning threshold range in the first air-conditioning threshold range can be set greater than the upper limit value of the largest heating threshold range in the first heating threshold range.

[0180] In other possible embodiments, the number of first air-conditioning threshold ranges is equal to the number of first heating threshold ranges and corresponds one to one. The air-conditioning threshold range that does not include the compressor speed switching item in the air-conditioning control strategy is used as the third air-conditioning threshold range, and the air-conditioning threshold range adjacent to the third air-conditioning threshold range and including the compressor speed switching item is used as the fourth air-conditioning threshold range; the common endpoint value between the third air-conditioning threshold range and the fourth air-conditioning threshold range is used as the first endpoint value, and the common endpoint value between the heating threshold range corresponding to the third air-conditioning threshold range and the heating threshold range corresponding to the fourth air-conditioning threshold range is used as the second endpoint value; the first endpoint value is set equal to the second endpoint value.

[0181] That is, in the embodiment of the present application, since increasing the compressor speed will place higher requirements on the vehicle's power consumption, increase noise, and aggravate the wear of components, when the air-conditioning control strategy corresponding to the third air-conditioning threshold range is used to perform the defrosting and defogging process, in order to avoid the temperature difference from entering the fourth air-conditioning threshold range, the heating control strategy corresponding to the heating threshold range corresponding to the third air-conditioning threshold range can be used at the same time to control the heating film, so that the heating film and the air-conditioning work together to perform defrosting and defogging.

[0182] In other possible embodiments, since increasing the blower air volume and increasing the window blowing ratio will have a greater impact on the user's physical sensation, before entering the first air-conditioning threshold range corresponding to increasing the blower air volume and increasing the window blowing ratio, a heating film can be selected to heat the car windows. Therefore, the range length of the first air-conditioning threshold range can be set to be greater than the range length of the heating threshold range corresponding to the first air-conditioning threshold.

[0183] The range length refers to the difference between the upper limit and the lower limit of the threshold range. The larger the difference between the upper limit and the lower limit, the longer the range length corresponding to the threshold range.

[0184] For further understanding, the following example is used to illustrate:

[0185] For example: Figure 9 As shown, the first air conditioning threshold range includes: [A, B], (B, C], (C, D], (D, E], and the first heating threshold range includes: [X, Y], (Y, Z], (Z, R], (R, Q]; wherein the first heating threshold range corresponding to the first air conditioning threshold range [A, B] is [X, Y], the first heating threshold range corresponding to the first air conditioning threshold range (B, C] is (Y, Z], the first heating threshold range corresponding to the first air conditioning threshold range (C, D] is (Z, R], and the first heating threshold range corresponding to the first air conditioning threshold range (D, E] is (R, Q]; the air conditioning items included in the first air conditioning threshold range [A, B] are: controlling the air conditioning to increase the outside circulation ratio, the air conditioning items included in the first air conditioning threshold range (B, C] are to control the air conditioning to increase the external circulation ratio and increase the compressor speed; the air conditioning items included in the first air conditioning threshold range (C, D] are to control the air conditioning to increase the external circulation ratio, increase the compressor speed, increase the blower speed, and increase the window blowing ratio; the air conditioning items included in the first air conditioning threshold range (D, E] are to control the air conditioning to increase the external circulation ratio, increase the compressor speed, increase the blower speed, and increase the window blowing ratio; and the increase in the blower speed in (D, E] is greater than the increase in the blower speed in (C, D], and the increase in the window blowing ratio in (D, E] is greater than the increase in the window blowing ratio in (C, D];

[0186] Among them, the range length of [A, B] is greater than the range length of [X, Y], the range length of (B, C] is greater than the range length of (Y, Z], the range length of (C, D] is greater than the range length of (Z, R], and the range length of (D, E] is greater than the range length of (R, Q];

[0187] The endpoint value shared by the first air-conditioning threshold range [A, B] and the first air-conditioning threshold range (B, C] is the value B, the endpoint value shared by the first heating threshold range [X, Y] and the first heating threshold range (Y, Z] is the value Y, and the value B is equal to the value Y;

[0188] The A value in the first air conditioning threshold range [A, B] is greater than the Y value in the first heating threshold range [X, Y];

[0189] Based on this, when there is a risk of fogging in the vehicle, the air-conditioning control strategy corresponding to the first air-conditioning threshold range [A, B] is first adopted to perform defrosting and defogging. If the temperature difference is still decreasing and enters the first heating threshold range [X, Y], the heating control strategy corresponding to the first heating threshold range [X, Y] is adopted to control the heating film at the same time. If the temperature difference is still decreasing and enters the first air-conditioning threshold range (B, C] and the first heating threshold range (Y, Z], the air-conditioning control strategy corresponding to the first air-conditioning threshold range (B, C] is adopted to perform defrosting and defogging, and the heating control strategy corresponding to the first heating threshold range (Y, Z] is adopted to control the heating film at the same time. If the temperature difference is still decreasing, at this time The temperature difference first enters the interval corresponding to the first heating threshold range (Z, R], and the heating control strategy corresponding to the first heating threshold range (Z, R] is adopted to control the heating film; if the temperature difference enters the interval corresponding to the first air-conditioning threshold range (C, D], the air-conditioning control strategy corresponding to the first air-conditioning threshold range (C, D] is adopted to perform defrosting and defogging; if the temperature difference enters the interval corresponding to the first heating threshold range (R, Q], the heating control strategy corresponding to the first heating threshold range (R, Q] is adopted to control the heating film; if the temperature difference enters the first air-conditioning threshold range (D, E], the air-conditioning control strategy corresponding to the first air-conditioning threshold range (D, E] is adopted to perform defrosting and defogging.

[0190] In some other possible embodiments, the related art generally adopts the following Figure 10 The heating film is arranged in the manner shown. Since it is necessary to arrange temperature sensors and other equipment in the front windshield, there is a target area in the front windshield that is not covered by the heating film. Therefore, in order to achieve uniform heating of the heating film, it can be as follows Figure 11As shown, a first heating strip is installed in the target area of ​​the front windshield that is not covered by the heating film. The first heating strip is placed below the second heating strip and above the third heating strip. The first, second, and third heating strips are used to circulate current. The area through which the heating strip passes is where the current flows when the heating film is powered on. By installing the heating strips, the temperature of the area not covered by the heating film can be increased, thereby achieving uniform heating. The heating strips can be made of copper foil; the heating strips can also be made of other materials. This application does not limit the material of the heating strips.

[0191] In such Figure 11 In the case shown, the heating effect of the heating film is better, so you can use Figure 12 The air conditioning threshold and the heating threshold are set in the manner shown, wherein: the first air conditioning threshold range includes: [A, B], (B, C], (C, D], (D, E], and the first heating threshold range includes: [X, Y], (Y, Z], (Z, R], (R, Q]; wherein the first heating threshold range corresponding to the first air conditioning threshold range [A, B] is [X, Y], the first heating threshold range corresponding to the first air conditioning threshold range (B, C] is (Y, Z], the first heating threshold range corresponding to the first air conditioning threshold range (C, D] is (Z, R], and the first heating threshold range corresponding to the first air conditioning threshold range (D, E] is (R, Q]; the air conditioning items included in the first air conditioning threshold range [A, B] are : Controlling the air conditioner to increase the external circulation ratio, the air conditioning items included in the first air conditioning threshold range (B, C] are controlling the air conditioner to increase the external circulation ratio and increase the compressor speed, the air conditioning items included in the first air conditioning threshold range (C, D] are controlling the air conditioner to increase the external circulation ratio, increase the compressor speed, increase the blower speed, and increase the window blowing ratio, and the air conditioning items included in the first air conditioning threshold range (D, E] are controlling the air conditioner to increase the external circulation ratio, increase the compressor speed, increase the blower speed, and increase the window blowing ratio; and the increase magnitude of the blower speed in (D, E] is greater than the increase magnitude of the blower speed in (C, D], and the increase magnitude of the window blowing ratio in (D, E] is greater than the increase magnitude of the window blowing ratio in (C, D];

[0192] Among them, the range length of [A, B] is greater than the range length of [X, Y], the range length of (B, C] is greater than the range length of (Y, Z], the range length of (C, D] is greater than the range length of (Z, R], and the range length of (D, E] is greater than the range length of (R, Q];

[0193] The A value in the first air conditioning threshold range [A, B] is greater than the Y value in the first heating threshold range [X, Y];

[0194] The endpoint value shared by the first air-conditioning threshold range [A, B] and the first air-conditioning threshold range (B, C] is the value B, the endpoint value shared by the first heating threshold range [X, Y] and the first heating threshold range (Y, Z] is the value Y, and the value B is less than the value Y;

[0195] Based on this, when there is a risk of fogging in the vehicle, the air-conditioning control strategy corresponding to the first air-conditioning threshold range [A, B] is first adopted to perform defrosting and defogging. If the temperature difference is still decreasing and enters the first heating threshold range [X, Y], the heating control strategy corresponding to the first heating threshold range [X, Y] is adopted to control the heating film at the same time; if the temperature difference is still decreasing, first enter the first heating threshold range (Y, Z], and adopt the heating control strategy corresponding to the first heating threshold range (Y, Z] to control the heating film; if the temperature difference is still decreasing and enters the first air-conditioning threshold range (B, C], the air-conditioning control strategy corresponding to the first air-conditioning threshold range (B, C] is adopted to perform defrosting and defogging; if the temperature difference is still decreasing, When decreasing, at this time, the temperature difference first enters the interval corresponding to the first heating threshold range (Z, R], and the heating control strategy corresponding to the first heating threshold range (Z, R] is adopted to control the heating film; if the temperature difference enters the interval corresponding to the first air-conditioning threshold range (C, D], the air-conditioning control strategy corresponding to the first air-conditioning threshold range (C, D] is adopted to perform defrosting and defogging; if the temperature difference enters the interval corresponding to the first heating threshold range (R, Q], the heating control strategy corresponding to the first heating threshold range (R, Q] is adopted to control the heating film, and if the temperature difference enters the first air-conditioning threshold range (D, E], the air-conditioning control strategy corresponding to the first air-conditioning threshold range (D, E] is adopted to perform defrosting and defogging.

[0196] That is, in the embodiment of the present application, before adopting the air-conditioning control strategy corresponding to increasing the compressor speed with higher power consumption, a heating film control strategy with uniform heating, low power consumption and no user perception is first adopted to control the heating film.
