[0023] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0024] The cleanliness of the vehicle air conditioning system directly affects the air quality in the car and the operating efficiency of the air conditioning system. Therefore, car owners pay more and more attention to the cleaning and maintenance of the vehicle air conditioning system to ensure its normal operation and provide a comfortable in-car environment. Although traditional manual cleaning methods can achieve a certain cleaning effect, there are many inconveniences and limitations, such as time-consuming, complicated operation, and the need for professional tools and cleaning agents. In addition, since car owners may not have sufficient professional knowledge and skills, it is easy to damage the air conditioning system when cleaning by themselves, resulting in increased maintenance costs.

[0025] As the automobile industry develops towards intelligence and automation, the automatic cleaning technology of vehicle air conditioners has begun to be applied to vehicles. The relevant automatic cleaning technology of vehicle air conditioners realizes automatic detection, evaluation and cleaning of the air conditioning system through sensors and controllers integrated in the vehicle air conditioning system; among them, it judges whether the air conditioner needs self-cleaning through cleaning parameters (such as air volume parameters, dust particle size parameters, air odor parameters, etc.). If it is determined that the vehicle air conditioner needs self-cleaning, the vehicle air conditioner is controlled to perform self-cleaning of the air filter. The cleaning process can include preset steps such as heating, ventilation, spraying detergent and drying to ensure that internal dirt is removed and microbial growth is inhibited.

[0026] However, the related automatic cleaning technology of vehicle air conditioners detects the concentration of hazardous substances (such as air volume parameters, dust particle size parameters, air odor parameters, etc.) through sensors integrated in the vehicle air conditioning system. When the concentration of hazardous substances reaches a certain preset threshold, the self-cleaning program will be started. However, the accumulation of hazardous substances will increase the difficulty of cleaning, and a greater cleaning intensity is required. For example, if the vehicle air conditioner has not been cleaned for a long time, the internal dirt and microorganisms may form stubborn attachments that are difficult to remove by conventional cleaning methods; in addition, a greater cleaning intensity may have a destructive effect on the air conditioning device, such as damaging the filter, air duct and other components. On the other hand, the increase in the concentration of hazardous substances is not necessarily entirely caused by the air conditioner. If the vehicle is driving in a heavily polluted environment, the concentration of hazardous substances detected may also be very high. Even if there is no problem with the vehicle air conditioner itself, the cleaning program may be triggered by mistake, resulting in unnecessary cleaning and energy waste.

[0027] In view of the above problems, the embodiment of the present application provides a cleaning control method for a vehicle air conditioner. By obtaining the current operating parameters of the vehicle air conditioner in the vehicle, by obtaining detailed operating parameters of the vehicle air conditioner, the operating status of the air conditioner can be more comprehensively understood, rather than just relying on the concentration of hazardous substances. When it is determined based on the current operating parameters that the vehicle air conditioner needs to be self-cleaned, the environmental parameters inside the vehicle and the environmental parameters outside the vehicle are obtained to provide more information for subsequent decision-making. According to at least one of the current operating parameters of the vehicle air conditioner, the environmental parameters inside the vehicle, and the environmental parameters outside the vehicle, the cleaning control parameters of the vehicle air conditioner are determined, wherein the cleaning control parameters include at least one of the cleaning intensity, the cleaning mode, and the cleaning duration, and the most appropriate cleaning intensity, mode, and duration are intelligently determined. Through multi-dimensional data, the cleaning control parameters of the vehicle air conditioner are dynamically adjusted. According to the cleaning control parameters of the vehicle air conditioner, the vehicle air conditioner is controlled to perform self-cleaning and specific cleaning operations are performed, so that each cleaning can achieve the expected effect, while protecting the air conditioning components from damage caused by excessive cleaning. In this way, the present application can accurately identify when the vehicle air conditioner needs self-cleaning by continuously monitoring the operating parameters of the vehicle air conditioner, thereby improving cleaning efficiency and effectiveness, preventing long-term accumulation of pollutants, reducing the difficulty of subsequent cleaning, and solving the problem of inaccurate judgment of whether the vehicle air conditioner needs self-cleaning based on the concentration threshold of hazardous substances in related technologies. It not only ensures the cleaning effect, but also avoids damage to the air-conditioning components due to excessive cleaning, improves the timeliness and accuracy of cleaning, reduces unnecessary cleaning operations, and improves the long-term performance and life of the vehicle air conditioner.

[0028] The cleaning control method and device of the vehicle air conditioner in the present application will be described in detail below with reference to the accompanying drawings.

[0029] Figure 1It is a flow chart of a cleaning control method for a vehicle air conditioner provided in an embodiment of the present application. Figure 1 The cleaning control method of the vehicle air conditioner can be executed by a vehicle controller, a vehicle terminal or a vehicle air conditioning system. Figure 1 As shown, the cleaning control method of the vehicle air conditioner includes:

[0030] Step 101, obtaining current operating parameters of the vehicle air conditioner.

[0031] In some embodiments, the current operating parameters of the vehicle air conditioner may include the cumulative operating time of the air conditioner since the last self-cleaning of the vehicle air conditioner, the cumulative operating time of the heating mode since the last self-cleaning of the vehicle air conditioner, the cumulative operating time of the cooling mode since the last self-cleaning of the vehicle air conditioner, and the cumulative vehicle mileage, air conditioning mode, air conditioning temperature, etc. corresponding to the vehicle air conditioner operating time since the last self-cleaning of the vehicle air conditioner.

[0032] Among them, the cumulative operating time of the air conditioner since the last self-cleaning of the vehicle air conditioner is the total operating time of the vehicle air conditioner since the last cleaning, the cumulative operating time of the heating mode since the last self-cleaning of the vehicle air conditioner is the cumulative operating time of the vehicle air conditioner in the heating mode since the last cleaning, the cumulative operating time of the cooling mode since the last self-cleaning of the vehicle air conditioner is the cumulative operating time of the vehicle air conditioner in the cooling mode since the last cleaning, and the cumulative mileage of the vehicle corresponding to the operating time of the vehicle air conditioner is the cumulative mileage of the vehicle during the operation of the vehicle air conditioner since the last cleaning.

[0033] When obtaining the current operating parameters of the vehicle's air conditioner, the current operating parameters of the vehicle's air conditioner can be directly obtained from the vehicle's air-conditioning control system; wherein, the current operating parameters of the vehicle's air conditioner can be obtained once every preset period of time, and the preset period of time can be 1 minute, without specific restrictions here.

[0034] The operating parameters of the vehicle air conditioner can help determine the workload of the air conditioner and the degree of possible accumulation of pollutants, and thus determine when and how to clean the vehicle air conditioner. In addition, based on the analysis of the operating parameters of the vehicle air conditioner, cleaning operations can be performed in advance before the harmful substances attached to the vehicle air conditioner accumulate to an excessively high level, preventing the degradation of the air conditioner performance and the impact of harmful substances on the health of passengers; in addition, the cleaning program is automatically triggered according to multiple parameters without manual intervention, and it is ensured that cleaning is performed at the most appropriate time.

[0035] Step 102 : When it is determined based on the current operating parameters that the vehicle air conditioner needs to be self-cleaned, obtain the environmental parameters inside the vehicle and the environmental parameters outside the vehicle.

[0036] In some embodiments, by continuously monitoring the operating parameters of the vehicle air conditioner, it is possible to determine whether to enter automatic air conditioning cleaning after the vehicle air conditioner is used based on the current operating parameters of the vehicle air conditioner to prevent the continuous accumulation of harmful substances (such as dust, bacteria or odors), thereby reducing the difficulty of subsequent cleaning and allowing the vehicle air conditioner to be in a clean state for a long time.

[0037] In addition, by judging whether the vehicle air conditioner needs self-cleaning through the current operating parameters, compared with the related art, when the detected harmful substances (such as dust, bacteria or odor) reach a preset level, the cleaning operation is triggered. The increase in the harmful substance parameters may also be caused by the vehicle driving in a heavily polluted environment. At this time, it may be misjudged as needing cleaning, triggering unnecessary cleaning operations. The present embodiment judges whether the vehicle air conditioner needs self-cleaning through the current operating parameters, which can more accurately judge whether self-cleaning is needed, thereby avoiding misjudgment and unnecessary cleaning operations.

[0038] The environmental parameters inside the vehicle may include temperature and humidity, and the environmental parameters outside the vehicle may include temperature and humidity.

[0039] When it is determined that the vehicle air conditioner needs to be self-cleaned based on the current operating parameters, the environmental parameters inside and outside the vehicle can be obtained through vehicle sensors or external data sources. The environmental parameters inside and outside the vehicle can provide references for formulating accurate cleaning strategies. For example, in a high temperature environment, the frequent operation of the vehicle air conditioner will cause a large amount of condensed water to form on the surface of the evaporator. If this water cannot be discharged in time, mold and bacteria may grow. Therefore, in this case, the evaporation of water on the evaporator can be accelerated by increasing ventilation or heating steps to prevent mold growth. At the same time, the cleaning intensity can be appropriately increased to remove moisture and pollutants attached to the evaporator. For another example, in a low temperature environment, the moisture content in the air is low, and dust and other particles are more likely to adhere to the inside of the vehicle air conditioner. Therefore, in this case, the ventilation operation can be strengthened to help remove loose dust and other particles, or a cooling-heating combination mode can be used to first cool the fixed attachments and then heat to discharge the water droplets containing dirt.

[0040] When it is determined based on the current operating parameters that the vehicle air conditioner needs to be self-cleaned, the environmental parameters inside the vehicle and the environmental parameters outside the vehicle are obtained, thereby avoiding the situation where the vehicle internal and external environmental parameters are ineffectively obtained when self-cleaning is not required. Of course, in some embodiments, the current operating parameters of the vehicle air conditioner, the environmental parameters inside the vehicle, and the environmental parameters outside the vehicle can also be obtained at the same time, thereby avoiding the secondary acquisition process of the parameters.

[0041] Step 103, determining the cleaning control parameters of the vehicle air conditioner based on the current operating parameters of the vehicle air conditioner, the environmental parameters inside the vehicle, and at least one of the environmental parameters outside the vehicle, wherein the cleaning control parameters include at least one of the cleaning intensity, the cleaning mode, and the cleaning time.

[0042] The cleaning control parameters are key settings in the vehicle air conditioning automatic cleaning system for controlling the self-cleaning operation of the vehicle air conditioning. The cleaning control parameters include at least one of the cleaning intensity, cleaning mode and cleaning time, so that each cleaning can achieve the best effect while protecting the air conditioning components and extending their service life.

[0043] Cleaning intensity refers to the force or energy level used during the cleaning process, which determines the cleaning operation's ability to remove pollutants. For example, in a high-temperature environment, frequent operation of the vehicle air conditioner will cause a large amount of condensed water to form on the evaporator surface. If this water cannot be discharged in time, mold and bacteria may grow. Therefore, a more powerful cleaning method can be used for this situation. The cleaning mode is a specific cleaning process or method selected according to different environmental conditions and usage requirements. The cleaning mode can include hot air mode, fan mode, and a combination of hot and cold modes. The cleaning time is the length of time required for the entire cleaning process, and the cleaning time determines the duration of the cleaning operation.

[0044] In some embodiments, cleaning control parameters (such as cleaning intensity, mode and duration) are dynamically adjusted according to different environmental conditions (environmental parameters inside the vehicle and environmental parameters outside the vehicle) and usage conditions (current operating parameters of the vehicle air conditioner), thereby providing rich information through multi-dimensional parameter data and selecting the most appropriate cleaning intensity, cleaning mode and cleaning duration based on this, which can not only ensure the cleaning effect but also protect the air conditioning components and avoid damage caused by excessive cleaning.

[0045] By comprehensively considering the current operating parameters of the vehicle air conditioner and the environmental parameters inside and outside the vehicle, cleaning control parameters can be formulated more accurately, solving the problems caused by single threshold-triggered cleaning in related technologies, achieving more timely and effective cleaning operations, reducing cleaning difficulty and risks, and improving the long-term performance and life of the equipment, so that the vehicle air conditioning system can always remain in a clean state.

[0046] Step 104 , controlling the vehicle air conditioner to perform self-cleaning according to the cleaning control parameters of the vehicle air conditioner.

[0047] After determining the cleaning control parameters of the vehicle air conditioner, the vehicle air conditioner can be controlled to perform self-cleaning based on the cleaning control parameters of the vehicle air conditioner, so that the self-cleaning effect of the vehicle air conditioner conforms to the current operating parameters of the vehicle air conditioner and the environmental parameters inside and outside the vehicle, thereby making the environment inside the vehicle meet the needs of users and improving the riding experience.

[0048] The cleaning control method of the vehicle air conditioner provided in the present application obtains detailed operating parameters of the vehicle air conditioner to more comprehensively understand the operating status of the air conditioner, rather than relying solely on the concentration of hazardous substances. When the vehicle air conditioner is determined to need self-cleaning based on the current operating parameters, the environmental parameters inside the vehicle and the environmental parameters outside the vehicle are obtained to provide more information for subsequent decision-making. The cleaning control parameters of the vehicle air conditioner are determined according to at least one of the current operating parameters of the vehicle air conditioner, the environmental parameters inside the vehicle, and the environmental parameters outside the vehicle, wherein the cleaning control parameters include at least one of the cleaning intensity, the cleaning mode, and the cleaning duration, and the most appropriate cleaning intensity, mode, and duration are intelligently determined. The cleaning control parameters of the vehicle air conditioner are dynamically adjusted through multi-dimensional data, thereby improving the overall cleaning efficiency and solving the problem of inaccurate determination of whether the vehicle air conditioner needs self-cleaning based on the threshold of hazardous substances in the related art. This ensures the cleaning effect and avoids damage to the air conditioner components due to excessive cleaning, thereby improving the timeliness and accuracy of cleaning, reducing unnecessary cleaning operations, and improving the user experience and the long-term performance of the vehicle air conditioner.

[0049] In some embodiments, as an example, taking a vehicle air conditioning system as an example, the vehicle air conditioning system includes a central processing unit (CPU) and an actuator. When the air conditioning is turned on, the CPU can be used to obtain the current operating parameters of the vehicle air conditioning in the vehicle. In particular, if the system does not record the current operating parameters, that is, the cumulative operating time of the air conditioning since the last self-cleaning of the vehicle air conditioning, the cumulative operating time of the heating mode, the cumulative operating time of the cooling mode, and the cumulative mileage of the vehicle corresponding to the running time of the vehicle air conditioning in the current operating parameters are not recorded, it can be considered that the vehicle has not turned on the vehicle air conditioning, that is, the current operating parameters can be set to 0.

[0050] When the CPU determines that the vehicle air conditioner needs to perform self-cleaning based on the current operating parameters, it obtains the environmental parameters inside the vehicle and the environmental parameters outside the vehicle, and determines the cleaning control parameters of the vehicle air conditioner according to at least one of the current operating parameters of the vehicle air conditioner, the environmental parameters inside the vehicle and the environmental parameters outside the vehicle; the cleaning control parameters of the vehicle air conditioner are the optimal configuration obtained by comprehensively analyzing the current operating parameters of the vehicle air conditioner, the environmental parameters inside the vehicle and the external environmental parameters; the actuator can be used to control the vehicle air conditioner to perform self-cleaning according to the cleaning control parameters of the vehicle air conditioner, and the specific steps of self-cleaning include preset heating, ventilation, spraying of detergent and drying, etc., and each step is performed according to the preset cleaning control parameters to ensure cleaning effect and safety.

[0051] In addition, the vehicle air-conditioning system can also be used for data storage. On the one hand, it stores the date and cleaning judgment data of each self-cleaning of the vehicle air-conditioning. The date of self-cleaning may include the timestamp from the judgment of the cleaning time of the vehicle air-conditioning to the completion of cleaning. The cleaning judgment data may be the current operating parameters of the vehicle air-conditioning, and whether the operating status of the air-conditioning is normal after cleaning. By storing the date and cleaning judgment data of each self-cleaning, a historical database of all vehicle air-conditioning cleaning activities can be maintained for a long time to facilitate subsequent analysis and optimization strategies. On the other hand, it can store user personalized settings, including user preferences for cleaning frequency, intensity, etc. User personalized setting information can provide users with a reference for services that meet user needs.

[0052] In addition, the vehicle air conditioning automatic cleaning system can control the vehicle air conditioning to perform self-cleaning through data analysis, which mainly includes continuously collecting and monitoring the operating parameters from the vehicle air conditioning control system, the environmental parameters inside the vehicle collected by the vehicle sensor, and the environmental parameters outside the vehicle. As the vehicle runs, the above data is updated in real time to ensure that the cleaning control parameters of the vehicle air conditioning are based on the latest data. According to the collected current operating parameters of the vehicle air conditioning, it can be analyzed whether the current state meets the preset self-cleaning trigger conditions. For example, if it is detected that the cumulative running time of the air conditioning since the last self-cleaning of the vehicle air conditioning exceeds a certain threshold, it can be determined that the vehicle air conditioning needs to be self-cleaned. At the same time, according to at least one of the current operating parameters of the vehicle air conditioning, the environmental parameters inside the vehicle, and the environmental parameters outside the vehicle, the cleaning control parameters of the vehicle air conditioning are determined, the most appropriate cleaning strategy is selected, and the cleaning control parameters of the determined vehicle air conditioning can be notified to the user through the vehicle's central control display screen or voice broadcast. After receiving the user's response instruction to perform self-cleaning, the vehicle air conditioning is controlled to perform self-cleaning according to the cleaning control parameters of the vehicle air conditioning.

[0053] Figure 2The data monitoring module 201 is a logical framework diagram of the automatic cleaning system of the vehicle air conditioner, wherein the data monitoring module 201 includes two submodules: a real-time monitoring module 202 and a data acquisition module 203. The real-time monitoring module 202 is used to continuously monitor the current operating parameters of the vehicle air conditioner, and the data acquisition module 203 is used to collect the environmental parameters inside the vehicle, the environmental parameters outside the vehicle and the data records of each self-cleaning. The data monitoring module 201 determines whether self-cleaning is required based on the current operating parameters of the vehicle air conditioner, determines self-cleaning at an appropriate time point, and avoids unnecessary cleaning operations; and combines the current operating parameters of the vehicle air conditioner, the environmental parameters inside the vehicle and the environmental parameters outside the vehicle to perform frequency judgment, cleaning intensity adjustment, cleaning mode judgment and cleaning time judgment to generate the cleaning control parameters of the vehicle air conditioner; and according to the cleaning control parameters of the vehicle air conditioner, controls the vehicle air conditioner to perform self-cleaning, records all data about the self-cleaning process, and obtains self-cleaning data records.

[0054] The conditions and thresholds for frequency judgment and cleaning intensity are shown in the following table:

[0055] Table 1 Conditions and thresholds corresponding to frequency judgment and cleaning intensity

[0056]

[0057]

[0058] In the related art, the automatic cleaning technology of vehicle air conditioners usually relies on the concentration of detected hazardous substances (such as dust, bacteria or odor) reaching a preset level to trigger the cleaning operation. However, when the vehicle is driving in a heavily polluted environment, the increased concentration of hazardous substances may also lead to the misjudgment that the vehicle air conditioner needs to be self-cleaned, resulting in inaccurate cleaning timing.

[0059] In view of the above problem, in some embodiments, the current operating parameters of the vehicle air conditioner include: the cumulative operating time of the air conditioner since the last self-cleaning of the vehicle air conditioner, the cumulative operating time of the heating mode, the cumulative operating time of the cooling mode, and the cumulative mileage of the vehicle corresponding to the operating time of the vehicle air conditioner;

[0060] Determine that the vehicle air conditioner needs to be self-cleaned based on the current operating parameters, including:

[0061] When it is determined that any current operating parameter is greater than or equal to the corresponding parameter threshold, it is determined that the vehicle air conditioner needs to be self-cleaned; or,

[0062] When it is detected that the current time reaches the target cleaning time, it is determined that the vehicle air conditioner needs to be self-cleaned, where the target cleaning time is determined based on the last self-cleaning time of the vehicle air conditioner and the target cleaning frequency currently corresponding to the vehicle air conditioner.

[0063] Among them, the cumulative running time T0 of the vehicle air conditioner since the last self-cleaning is the total running time of the vehicle air conditioner since the last cleaning. The longer the cumulative running time T0 of the vehicle air conditioner since the last self-cleaning, the more pollutants may be accumulated in the corresponding vehicle air conditioner, so regular cleaning is required to maintain performance; the parameter threshold t corresponding to the cumulative running time of the vehicle air conditioner since the last self-cleaning is a pre-set duration threshold.

[0064] The cumulative running time H0 of the heating mode is the cumulative running time of the vehicle air conditioner in the heating mode since the last cleaning. In the heating mode, condensation water is easily formed inside the air conditioner, increasing the risk of mold growth. The longer the corresponding cumulative running time H0 of the heating mode is, the more pollutants may accumulate in the corresponding vehicle air conditioner. The parameter threshold h corresponding to the cumulative running time of the heating mode since the last self-cleaning of the vehicle air conditioner is the pre-set time threshold.

[0065] The cumulative running time C0 of the cooling mode is the cumulative running time of the vehicle air conditioner in the cooling mode since the last cleaning. In the cooling mode, the vehicle air conditioner is prone to dust and bacteria. The longer the cumulative running time C0 of the cooling mode is, the more pollutants may accumulate in the corresponding vehicle air conditioner, which needs to be cleaned regularly to prevent pollution accumulation. The parameter threshold c corresponding to the cumulative running time of the cooling mode since the last self-cleaning of the vehicle air conditioner is the pre-set time threshold.

[0066] The vehicle cumulative mileage M0 corresponding to the vehicle air conditioner operation time is the cumulative mileage of the vehicle during the vehicle air conditioner operation since the last cleaning. The vehicle cumulative mileage M0 corresponding to the vehicle air conditioner operation time reflects the vehicle usage and helps to more comprehensively judge the cleaning needs. The greater the vehicle cumulative mileage M0 corresponding to the vehicle air conditioner operation time, the more pollutants may be accumulated in the corresponding vehicle air conditioner. The parameter threshold m corresponding to the vehicle cumulative mileage M0 is a pre-set mileage threshold.

[0067] Any current operating parameter greater than or equal to the corresponding parameter threshold may specifically include:

[0068] The cumulative running time T0 of the vehicle air conditioner since the last self-cleaning of the vehicle air conditioner is greater than or equal to the parameter threshold t corresponding to the cumulative running time of the vehicle air conditioner since the last self-cleaning of the vehicle air conditioner; or

[0069] The cumulative operation time H0 of the heating mode is greater than or equal to the parameter threshold h corresponding to the cumulative operation time of the heating mode; or

[0070] The cumulative operation time C0 of the cooling mode is greater than or equal to the parameter threshold c corresponding to the cumulative operation time of the cooling mode; or,

[0071] The vehicle cumulative mileage M0 corresponding to the vehicle air conditioner operation time is greater than or equal to a parameter threshold m corresponding to the vehicle cumulative mileage corresponding to the vehicle air conditioner operation time.

[0072] When any current operating parameter is greater than or equal to the corresponding parameter threshold, it is determined that the vehicle air conditioner needs to be self-cleaned. The parameter threshold corresponding to any current operating parameter can be obtained based on empirical data or experimental data, and can be flexibly adjusted according to user needs. This is not specifically limited here.

[0073] The current operating parameters can be obtained once every preset time period. When it is determined that any current operating parameter is greater than or equal to the corresponding parameter threshold, it can be considered that the pollutants have not yet accumulated seriously. In this case, controlling the vehicle air conditioner to perform self-cleaning can avoid the formation of stubborn dirt that is difficult to remove later. The corresponding cleaning intensity for lighter pollutants is also lower, which can prevent the problem of damage to the vehicle air conditioner due to the use of higher cleaning intensity.

[0074] In addition, the target cleaning frequency currently corresponding to the vehicle air conditioner is determined according to the current operating parameters of the vehicle air conditioner. The higher the target cleaning frequency currently corresponding to the vehicle air conditioner, the closer the interval between the last self-cleaning time and the target cleaning time. Conversely, the interval between the last self-cleaning time and the target cleaning time is farther. After determining the target cleaning frequency currently corresponding to the vehicle air conditioner according to the current operating parameters of the vehicle air conditioner, the current cleaning time can be determined, and then it can be detected whether the current time has reached the current cleaning time. When it is detected that the current time has reached the target cleaning time, it can be determined that the vehicle air conditioner needs to be self-cleaned, so that the vehicle air conditioner can be cleaned according to the determined frequency, maintain its efficient operation, and avoid false triggering caused by changes in the external environment.

[0075] In some embodiments, the process of obtaining the target cleaning frequency currently corresponding to the vehicle air conditioner includes:

[0076] When the accumulated operation time of the air conditioner or the accumulated mileage of the vehicle when the vehicle air conditioner is running is greater than or equal to the corresponding parameter threshold, the preset frequency value is determined as the target cleaning frequency;

[0077] When the cumulative operation time of the heating mode since the last self-cleaning of the vehicle air conditioner is greater than or equal to the corresponding heating time threshold, the target cleaning frequency is determined based on the preset frequency value and the first frequency adjustment coefficient corresponding to the heating mode; wherein the first frequency adjustment coefficient is greater than 1;

[0078] When the cumulative running time of the cooling mode since the last self-cleaning of the vehicle air conditioner is greater than or equal to the corresponding cooling time threshold, the target cleaning frequency is determined based on the preset frequency value and the second frequency adjustment coefficient corresponding to the cooling mode; wherein the second frequency adjustment coefficient is less than 1.

[0079] Among them, the preset frequency value fbase is a pre-set cleaning reference frequency, the first frequency adjustment coefficient α is a coefficient used to increase the cleaning frequency, which can be used to cope with the possible increased accumulation of dirt and bacteria in the heating mode, and the first frequency adjustment coefficient β is greater than 1; the second frequency adjustment coefficient α is a coefficient used to reduce the cleaning frequency, which can be used to cope with the possible less accumulation of dirt and bacteria in the cooling mode, and the second frequency adjustment coefficient α is less than 1.

[0080] When the cumulative operating time T0 of the vehicle air conditioner since the last self-cleaning of the vehicle air conditioner is greater than or equal to the parameter threshold t corresponding to the cumulative operating time of the vehicle air conditioner since the last self-cleaning of the vehicle air conditioner, the preset frequency value fbase is determined as the target cleaning frequency; when the cumulative vehicle mileage M0 corresponding to the operating time of the vehicle air conditioner is greater than or equal to the parameter threshold m corresponding to the cumulative vehicle mileage corresponding to the operating time of the vehicle air conditioner, the preset frequency value fbase is determined as the target cleaning frequency; in this way, when the usage time and vehicle driving distance of the vehicle air conditioner since the last cleaning reach a certain standard, it is considered that the basic cleaning requirements have been met. At this time, the preset frequency value is used as the target cleaning frequency, so that the vehicle air conditioner can be cleaned and maintained in time after long-term operation or vehicle driving a long distance, to prevent performance degradation caused by long-term use.

[0081] When the cumulative operation time H0 of the heating mode is greater than or equal to the parameter threshold h corresponding to the cumulative operation time of the heating mode, the cleaning effect in the heating mode is ensured by increasing the cleaning frequency for the special pollution risk in the heating mode (such as mold growth caused by condensed water), and the cleaning frequency is increased. When determining the target cleaning frequency based on the preset frequency value and the first frequency adjustment coefficient corresponding to the heating mode, the preset frequency value fbase and the first frequency adjustment coefficient β corresponding to the heating mode can be multiplied, and the multiplication result can be determined as the target cleaning frequency; or, based on the predetermined preset frequency value and the weight coefficient corresponding to the multiplication result, the preset frequency value and the multiplication result are weighted and summed to obtain the target cleaning frequency.

[0082] When the cumulative operating time C0 of the cooling mode is greater than or equal to the parameter threshold c corresponding to the cumulative operating time of the cooling mode, when the cooling mode is running, the accumulation of dirt and bacteria inside the air conditioner may be less, and it is necessary to balance the cleaning effect and resource consumption by reducing the cleaning frequency. In addition, when determining the target cleaning frequency based on the preset frequency value and the second frequency adjustment coefficient corresponding to the cooling mode, the preset frequency value fbase and the second frequency adjustment coefficient α corresponding to the cooling mode can be multiplied, and the multiplication result is determined as the target cleaning frequency; or, based on the predetermined preset frequency value and the weight coefficient corresponding to the multiplication result, respectively, the preset frequency value and the multiplication result are weighted summed to obtain the target cleaning frequency.

[0083] For example, as an example, the process of obtaining the target cleaning frequency currently corresponding to the vehicle air conditioner can be expressed by the following formula:

[0084]

[0085] Where, represents the cumulative operation time of the air conditioner since the last self-cleaning of the vehicle air conditioner, and t represents the threshold value corresponding to the cumulative operation time of the air conditioner, which can be in hours;

[0086] M0 represents the cumulative mileage of the vehicle when the vehicle air conditioner is running since the last self-cleaning of the vehicle air conditioner, and m represents the threshold value corresponding to the cumulative mileage, which can be in meters or kilometers;

[0087] C0 represents the cumulative running time of the cooling mode since the last self-cleaning of the vehicle air conditioner, and c represents the cooling time threshold corresponding to the cooling mode, in hours;

[0088] H0 represents the cumulative running time of the heating mode since the last self-cleaning of the vehicle air conditioner, and h represents the heating time threshold corresponding to the heating mode, in hours;

[0089] F(M) represents the target cleaning frequency, α and β are constants, and fbase represents the preset frequency value, which can be set by the user or obtained based on experimental data or empirical data; when the cumulative operation time of the air conditioner or the cumulative mileage of the vehicle reaches the corresponding parameter threshold, or according to the judgment of the current operation mode, the cumulative operation time of a certain mode reaches the corresponding parameter threshold, the target cleaning frequency is calculated according to the above formula by adjusting the cleaning frequency. For example, when the air conditioner mode is cooling, α is 0.8, and the cleaning frequency is reduced. When the air conditioner mode is heating, β is 1.2, and the cleaning frequency is increased.

[0090] In this way, the cleaning frequency is dynamically determined by comparing the accumulated operating time of the air conditioner, the accumulated mileage, the accumulated operating time of the heating mode and the accumulated operating time of the cooling mode with the corresponding parameter thresholds, and the cleaning program is automatically triggered according to multiple parameters to ensure that the best cleaning lens can be maintained under different environmental conditions. It is more scientific and reasonable, without the need for human intervention, and ensures that cleaning is performed at the most appropriate time, so that the accumulation of dirt on components such as the evaporator and condenser can be reduced, the failure rate can be reduced, and the air-conditioning system can operate more efficiently and consume less energy, extending the service life of the system, effectively reducing the breeding of bacteria and viruses in the car, improving the air quality in the car, reducing the odor inside the air-conditioning system, and improving the riding experience. It avoids the possibility that fixed-mode cleaning may not be able to effectively cope with different degrees and types of pollution, and energy consumption and damage to the vehicle air conditioner caused by excessive cleaning or unnecessary cleaning operations.

[0091] In some embodiments, determining the cleaning control parameter of the vehicle air conditioner according to at least one of the current operating parameters of the vehicle air conditioner, the environmental parameters inside the vehicle, and the environmental parameters outside the vehicle includes:

[0092] Determine the cleaning intensity of the vehicle air conditioner according to the environmental parameters inside the vehicle and the environmental parameters outside the vehicle;

[0093] Determine the cleaning time of the vehicle air conditioner according to the current operating parameters of the vehicle air conditioner;

[0094] The cleaning mode of the vehicle air conditioner is determined based on the environmental parameters inside the vehicle, the environmental parameters outside the vehicle and the current operating parameters of the vehicle air conditioner; wherein the cleaning modes include a hot air mode for cleaning by hot air, a fan mode for cleaning by a fan and a combined hot and cold mode for cleaning by both cooling and heating.

[0095] Among them, the hot air mode is to clean the car air conditioner with hot air. It is suitable for cold seasons or humid environments. It uses hot air to remove attachments and moisture condensed by internal cold air, which can effectively prevent the growth of mold. The fan mode is to remove dust and odors through ventilation. It is suitable for lighter pollution conditions, such as short-distance driving or short air conditioning usage time. For example, the total air conditioning usage time reaches the threshold, but the actual mileage is very small, or the mileage is reached, but the actual usage time is very small. The combined hot and cold mode is to clean through cooling and heating together. For example, use cold air to remove surface dirt first, and then use hot air to dry. It is suitable for highly polluted conditions to ensure comprehensive cleaning.

[0096] In some embodiments, the environmental parameters inside the vehicle and the environmental parameters outside the vehicle can reflect the environmental conditions inside and outside the vehicle. Based on the environmental parameters inside the vehicle and the environmental parameters outside the vehicle, the cleaning intensity required for the air-conditioning system can be judged more accurately. After comprehensive analysis, the cleaning intensity of the vehicle air conditioner can be determined, thereby achieving the best cleaning effect.

[0097] In addition, cleaning time is an important parameter to ensure cleaning effect and improve cleaning efficiency. Reasonable cleaning time can help the air conditioning system to be fully cleaned while avoiding unnecessary energy waste. According to the current operating parameters of the car air conditioner and the setting of the cleaning intensity, the cleaning time can be flexibly adjusted to determine the cleaning time of the car air conditioner to prevent the accumulation of pollutants while ensuring cleaning efficiency. For example, if the car air conditioner is in a high-load working state for a long time (such as frequent cooling or heating), the cleaning time can be increased to ensure thorough cleaning.

[0098] In addition, the choice of cleaning mode directly affects the cleaning effect and energy efficiency. According to the environmental parameters inside the vehicle, the environmental parameters outside the vehicle and the current operating parameters of the vehicle air conditioner, the most suitable cleaning mode is intelligently selected. The cleaning mode of the vehicle air conditioner cooperates with factors such as cleaning intensity and cleaning time to jointly determine the cleaning effect, so that the air conditioning system can be cleaned most effectively, while reducing energy consumption and protecting equipment.

[0099] In addition, in other embodiments, users can set the cleaning intensity, cleaning time and cleaning mode according to their own needs. The vehicle air-conditioning system performs cleaning operations of the vehicle air-conditioning by responding to the setting parameters of the cleaning control parameters input by the user, thereby improving the flexibility of the system and user experience.

[0100] According to the current operating parameters of the vehicle air conditioner, the environmental parameters inside the vehicle and the environmental parameters outside the vehicle, the most suitable cleaning strategy, namely the cleaning control parameters, is selected according to the specific usage conditions. This not only solves the limitations of fixed-mode cleaning in related technologies, but also optimizes resource utilization, improves cleaning effects and extends the service life of the air-conditioning system.

[0101] In some embodiments, the environmental parameter outside the vehicle includes a temperature value, and the environmental parameter inside the vehicle includes a humidity value;

[0102] The cleaning intensity of the vehicle air conditioner is determined based on the environmental parameters inside and outside the vehicle, including:

[0103] When the temperature value is not within the preset temperature range or the humidity value exceeds the preset humidity threshold, determining the cleaning intensity to be the first cleaning intensity;

[0104] When the temperature value is within the preset temperature range and the humidity value does not exceed the preset humidity threshold, determining the cleaning intensity to be the second cleaning intensity;

[0105] The first cleaning intensity is greater than the second cleaning intensity.

[0106] In some embodiments, the preset temperature range is a preset suitable temperature interval, for example, the preset temperature range may be 10-35° C., wherein 10° C. is a low temperature threshold lt, and 35° C. is a high temperature threshold ht.

[0107] If the temperature value LT0 in the car is not within the preset temperature range, it indicates that it is currently in a high or low temperature state. The high or low temperature environmental conditions have an adverse effect on the air-conditioning system or the environment inside the car. Therefore, under this condition, a higher cleaning force is required during self-cleaning.

[0108] The preset humidity threshold hu is a preset maximum humidity limit. For example, the preset humidity threshold hu can be 60%. If the humidity value HU0 exceeds the preset humidity threshold, it indicates that the humidity in the vehicle is high at this time. High humidity may cause dust and bacteria to adhere more easily to the evaporator surface, so more frequent or strong cleaning is required.

[0109] If the temperature value LT0 ≤ low temperature threshold lt, or the temperature value LT0 ≥ High temperature threshold ht, or humidity value HU0 ≥ The preset humidity threshold hu, at this time the temperature value is not in the preset temperature range or the temperature value exceeds the preset humidity threshold, the environmental conditions will increase the pollution risk of the air-conditioning system, and a stronger cleaning intensity is required, so the cleaning intensity is determined to be the first cleaning intensity; if the low temperature threshold lt<temperature value LT0<high temperature threshold ht, and the humidity value HU0<preset humidity threshold hu, at this time the temperature value is in the preset temperature range and the humidity value does not exceed the preset humidity threshold, the environmental conditions will not increase the pollution risk of the air-conditioning system, and a stronger cleaning intensity is not required, so the cleaning intensity is determined to be the second cleaning intensity.

[0110] For example, as an example, the cleaning intensity of the car air conditioner can be expressed by the following formula:

[0111]

[0112] Among them, S(i) represents the cleaning intensity of the vehicle air conditioner, S1base represents the first cleaning intensity, S2base represents the second cleaning intensity, when the temperature value LT0 ≤ the low temperature threshold lt, or the temperature value HT0 ≥ High temperature threshold ht, or humidity value HU0 ≥When the humidity threshold hu is preset, the cleaning intensity is the first cleaning intensity S1base. When the low temperature threshold lt<temperature value LT0<high ​​temperature threshold ht, and the humidity value HU0<preset humidity threshold hu, the cleaning intensity is the second cleaning intensity S2base.

[0113] In addition, the second cleaning intensity may be a preset reference cleaning intensity, and the first cleaning intensity may be obtained based on the second cleaning intensity and a preset cleaning intensity coefficient, for example, the first cleaning intensity may be the product of the second cleaning intensity and a preset cleaning intensity coefficient, or the first cleaning intensity may be a weighted sum of the second cleaning intensity and the above product. The cleaning intensity coefficient is greater than 1.

[0114] By real-time monitoring and judging the environmental parameters inside and outside the vehicle and selecting the appropriate cleaning intensity based on the judgment results, the cleaning effect can be guaranteed while avoiding unnecessary waste of resources, effectively optimizing the performance of the vehicle air-conditioning system and the interior environment.

[0115] In some embodiments, determining the cleaning time of the vehicle air conditioner according to the current operating parameters of the vehicle air conditioner includes:

[0116] For any current operating parameter, when the current operating parameter is greater than or equal to the corresponding parameter threshold, the cleaning time of the vehicle air conditioner is determined according to the preset cleaning time and the time increment corresponding to the current operating parameter; wherein,

[0117] The duration increment corresponding to each current operating parameter is determined based on each current operating parameter and a parameter threshold corresponding to the current operating parameter.

[0118] Specifically, the preset cleaning time Tbase is the default cleaning time, which can be used as the basis for the cleaning time. The time increment corresponding to the current operating parameter can quantify the impact of the current operating parameter exceeding the threshold on the cleaning time, so that the cleaning time matches the actual usage.

[0119] Optionally, determining the cleaning time of the vehicle air conditioner according to a preset cleaning time and a time increment corresponding to the current operating parameters includes:

[0120] When the cumulative operation time T0 of the air conditioner since the last self-cleaning of the vehicle air conditioner is greater than or equal to the parameter threshold value t corresponding to the cumulative operation time of the air conditioner since the last self-cleaning of the vehicle air conditioner, the time increment corresponding to the cumulative operation time of the air conditioner is determined according to the cumulative operation time of the air conditioner and the parameter threshold value corresponding to the cumulative operation time of the air conditioner, and the cleaning time of the vehicle air conditioner is determined according to the preset cleaning time and the time increment corresponding to the cumulative operation time of the air conditioner;

[0121] When the cumulative operation time H0 of the heating mode is greater than or equal to the parameter threshold value h corresponding to the cumulative operation time of the heating mode, the time increment corresponding to the cumulative operation time of the heating mode is determined according to the cumulative operation time of the heating mode and the parameter threshold value corresponding to the cumulative operation time of the heating mode, and the cleaning time of the vehicle air conditioner is determined according to the preset cleaning time and the time increment corresponding to the cumulative operation time of the heating mode;

[0122] When the cumulative operation time C0 of the cooling mode is greater than or equal to the parameter threshold value c corresponding to the cumulative operation time of the cooling mode, the time increment corresponding to the cumulative operation time of the cooling mode is determined according to the cumulative operation time of the cooling mode and the parameter threshold value corresponding to the cumulative operation time of the cooling mode, and the cleaning time of the vehicle air conditioner is determined according to the preset cleaning time and the time increment corresponding to the cumulative operation time of the cooling mode;

[0123] When the vehicle's cumulative mileage M0 corresponding to the vehicle's air-conditioning operating time is greater than or equal to the parameter threshold m corresponding to the vehicle's cumulative mileage corresponding to the vehicle's air-conditioning operating time, the time increment corresponding to the vehicle's cumulative mileage is determined according to the vehicle's cumulative mileage and the parameter threshold corresponding to the vehicle's cumulative mileage, and the cleaning time of the vehicle air conditioner is determined according to the preset cleaning time and the time increment corresponding to the vehicle's cumulative mileage.

[0124] Among them, when calculating the time increment corresponding to the cumulative operating time of the air conditioner, the cumulative operating time of the heating mode and the cumulative operating time of the cooling mode, the difference between each current operating parameter and the parameter threshold corresponding to the current operating parameter can be calculated first, and the product of the difference and the preset coefficient corresponding to the current operating parameter can be determined as the time increment, or the difference can be directly determined as the time increment.

[0125] When calculating the time increment corresponding to the vehicle's cumulative mileage, the difference between each current operating parameter and the parameter threshold corresponding to the current operating parameter can be calculated first, and the quotient of the difference and the average speed of the vehicle in the period corresponding to the cumulative operating time of the air conditioner can be calculated. The product of the quotient and the preset coefficient corresponding to the vehicle's cumulative mileage is then determined as the time increment, or the quotient is directly determined as the time increment.

[0126] For example, as an example, when the cumulative running time T0 of the air conditioner since the last self-cleaning of the vehicle air conditioner is greater than or equal to the parameter threshold t corresponding to the cumulative running time of the air conditioner since the last self-cleaning of the vehicle air conditioner, the cleaning time F(T) of the vehicle air conditioner can be determined according to the following formula:

[0127] F(T)=Tbase+δ*(T0-t), or F(T)=Tbase+(T0-t), where Tbase is the preset cleaning time, δ is the preset coefficient corresponding to the cumulative operating time of the air conditioner, which can be set according to experimental data or empirical data, and δ*(T0-t) or (T0-t) is the time increment corresponding to the cumulative operating time T0 of the air conditioner since the last self-cleaning of the vehicle air conditioner.

[0128] As another example, when the cumulative operation time H0 of the heating mode is greater than or equal to the parameter threshold h corresponding to the cumulative operation time of the heating mode, the cleaning time F(T) of the vehicle air conditioner can be determined according to the following formula:

[0129] F(T)=Tbase+ε*(H0-h), or F(T)=Tbase+(H0-h), where ε is the preset coefficient corresponding to the cumulative running time of the heating mode, and ε*(H0-h) or (H0-h) is the time increment corresponding to the cumulative running time H0 of the heating mode.

[0130] As another example, when the cumulative operation time C0 of the cooling mode is greater than or equal to the parameter threshold c corresponding to the cumulative operation time of the cooling mode, the cleaning time F(T) of the vehicle air conditioner can be determined according to the following formula:

[0131] F(T)=Tbase+∈*(C0-c), or F(T)=Tbase+(C0-c), where ∈ is the preset coefficient corresponding to the cumulative running time of the cooling mode, and ∈*(C0-c) or (C0-c) is the time increment corresponding to the cumulative running time C0 of the cooling mode.

[0132] As another example, when the vehicle cumulative mileage M0 corresponding to the vehicle air conditioner operation time is greater than or equal to the parameter threshold m corresponding to the vehicle cumulative mileage corresponding to the vehicle air conditioner operation time, the cleaning time F(T) of the vehicle air conditioner can be determined according to the following formula:

[0133] F(T)=Tbase+γ*(M0-m) / V, or F(T)=Tbase+(M0-m) / V, where γ is the preset coefficient corresponding to the vehicle's cumulative mileage, V is the average speed of the vehicle during the period corresponding to the cumulative operating time of the air conditioner, and γ*(M0-m) / V or (M0-m) / V is the time increment corresponding to the vehicle's cumulative mileage M0.

[0134] In this way, for any parameter in the current operating parameters of the vehicle air conditioner, when the parameter is greater than or equal to the corresponding parameter threshold, the preset cleaning time and the time increment corresponding to the parameter are added to obtain the cleaning time of the vehicle air conditioner. The cleaning time in different modes can be set according to actual conditions, and the cleaning time can be dynamically adjusted according to the actual use of the air-conditioning system, thereby improving the self-cleaning effect.

[0135] In some embodiments, the environmental parameter outside the vehicle includes a temperature value, the environmental parameter inside the vehicle includes a humidity value, and the current operating parameter of the vehicle air conditioner includes a current operating mode of the vehicle air conditioner;

[0136] Determine the cleaning mode of the vehicle air conditioner based on the environmental parameters inside the vehicle, the environmental parameters outside the vehicle, and the current operating parameters of the vehicle air conditioner:

[0137] When the current operation mode of the vehicle air conditioner is the cooling mode or the humidity value in the vehicle is greater than a preset humidity threshold, determining that the cleaning mode is the hot air mode;

[0138] When the cumulative running time of the vehicle air conditioner since the last self-cleaning is less than the corresponding parameter threshold, or when the cumulative vehicle mileage corresponding to the running time of the vehicle air conditioner since the last self-cleaning is less than the corresponding parameter threshold, the cleaning mode is determined to be the fan mode;

[0139] When the current operating mode of the vehicle air conditioner is the heating mode, the cleaning mode is determined to be the cold and hot combined mode; in the cold and hot combined mode, after the vehicle air conditioner turns on cooling, when it is detected that the temperature in the vehicle is lower than the preset temperature threshold, the vehicle air conditioner turns on heating.

[0140] In some embodiments, the environment outside the vehicle is strongly correlated with the cleanliness status of the vehicle air conditioner. Reasonable mode matching is performed according to the current operating mode (heating, cooling) and the current environment (temperature, humidity) to ensure the cleaning effect of the vehicle air conditioner.

[0141] Among them, when the temperature inside the car is high, the current operating mode is cooling. When the current operating mode of the car air conditioner is the cooling mode, the temperature outside the vehicle is high at this time. The condensation water of the cold air generated by the cooling mode under high temperature is easy to breed bacteria. At this time, setting the cleaning mode of the car air conditioner to the hot air mode helps to remove moisture and bacteria; when the humidity value in the vehicle is greater than the preset humidity threshold, that is, in a high humidity environment, moisture is easy to accumulate on the air conditioner evaporator and cause mold growth. Setting the cleaning mode of the car air conditioner to the hot air mode helps to evaporate moisture quickly and prevent mold growth, thereby effectively improving the air quality in the car.

[0142] During short-distance driving, for example, when the cumulative operating time of the vehicle air conditioner since the last self-cleaning is less than the corresponding parameter threshold, or when the cumulative vehicle mileage corresponding to the vehicle air conditioner operating time after the last self-cleaning is less than the corresponding parameter threshold, the vehicle air conditioner is used less frequently or the vehicle travels a shorter distance. In this case, the fan mode is selected, that is, the fan is used to remove dust and bacteria for light cleaning, and correspondingly, cold treatment or heating treatment is not used to keep the air conditioning coefficient clean.

[0143] In addition, in normal use, that is, when the current operating mode of the vehicle air conditioner is neither cooling mode nor heating mode, or in the case of short-distance driving or short-time use of the air conditioner, it may not be enough to accumulate enough pollutants to require a more complex cleaning mode. In this case, the cleaning mode of the vehicle air conditioner can also be determined as fan mode.

[0144] In addition, the environmental parameters inside the vehicle, the environmental parameters outside the vehicle, and the current operating parameters of the vehicle air conditioner can also be compared with the preset conditions corresponding to each cleaning mode. If the environmental parameters inside the vehicle, the environmental parameters outside the vehicle, and the current operating parameters of the vehicle air conditioner do not meet the preset conditions corresponding to the hot air mode, and the preset conditions corresponding to the hot and cold combined mode are also not met, then the cleaning mode of the vehicle air conditioner can be determined as the fan mode. Of course, if the preset conditions corresponding to the hot air mode are met, the cleaning mode of the vehicle air conditioner is determined to be the hot air mode; if the preset conditions corresponding to the hot and cold combined mode are met, the cleaning mode of the vehicle air conditioner is determined to be the hot air mode.

[0145] In addition, in a low temperature environment, the current operating mode is heating. When the current operating mode of the vehicle air conditioner is the heating mode, attached pollutants are easily generated. At this time, the cleaning mode of the vehicle air conditioner is determined to be a combined cold and hot mode. The cooling mode can be turned on first, and the cooling threshold can be designed according to the temperature threshold. For example, assuming that the temperature in the car is lower than the preset cooling threshold, it is considered that the attachment is fixed to the inner wall of the air conditioner, and then the heating mode is turned on to heat the water droplets containing the attachment and discharge them through the pipe, thereby obtaining a clean and contaminant-free evaporator.

[0146] Of course, after entering the combined cold and hot mode, you can also turn on the hot air of the air conditioner, and inform the driver of the cleaning mode of the car air conditioner by voice or prompt box.

[0147] By dynamically determining the cleaning mode based on the vehicle's current usage pattern and parameters inside and outside the vehicle, each cleaning can achieve the best effect while avoiding waste of resources.

[0148] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0149] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application. For details not disclosed in the embodiment of the device of the present application, please refer to the embodiment of the method of the present application.
