Description

Technical Field

[0001] This application relates to the field of automotive electronics technology, and in particular to a method and device for in-vehicle temperature control based on multiple systems after the vehicle is removed. Background Technology

[0002] With the continuous advancement of automotive technology and people's increasing demands for driving experience, in-vehicle environmental control has become an important component of modern automotive design. Especially in the high temperatures of summer, the rapid rise in in-vehicle temperature not only affects the comfort of passengers but can also damage the vehicle's electronic equipment. Therefore, how to effectively control in-vehicle temperature and provide a comfortable and safe driving environment has become a crucial issue for automakers and related technology research.

[0003] Currently, most existing methods for controlling the interior temperature after the vehicle leaves rely on a single temperature sensor to determine whether to activate the air conditioning system, thus regulating the interior temperature through the vehicle's built-in air conditioning system. While this method can control the interior temperature, it does not take into account the differentiated processing under different temperature conditions and lacks comprehensive consideration of external environmental factors such as light intensity. As a result, the interior temperature control effect is poor under extreme high temperature conditions, leading to a poor user experience. Summary of the Invention

[0004] In view of the above problems, this application provides a vehicle interior temperature control method and device based on multiple systems after leaving the vehicle. The main purpose is to comprehensively consider the differences in temperature conditions and external environmental factors to improve the effect of vehicle interior temperature control and enhance the user experience.

[0005] To solve the above-mentioned technical problems, this application proposes the following solution:

[0008] The current cooling scenario of the vehicle is determined based on the vehicle interior temperature and the vehicle surface light intensity.

[0009] If the scenario to be cooled is a high-temperature scenario to be cooled, then the vehicle is controlled to perform corresponding temperature control operations according to the first cooling strategy. The first cooling strategy is a dynamic collaborative control strategy based on ventilation and sunshade.

[0010] If the cooling scenario is the ultra-high temperature cooling scenario, the vehicle is controlled to perform corresponding temperature control operations according to the second cooling strategy. The second cooling strategy is a dynamic collaborative control strategy based on cooling, sunshade and energy replenishment.

[0011] Secondly, this application provides a multi-system in-vehicle temperature control device for use after leaving the vehicle, the device comprising:

The first cooling strategy is a dynamic collaborative control strategy based on ventilation and sunshade.

[0015] The second processing unit is configured to control the vehicle to perform corresponding temperature control operations according to the second cooling strategy if the determining unit confirms that the cooling scenario is the ultra-high temperature cooling scenario. The second cooling strategy is a dynamic collaborative control strategy based on cooling, sunshade and energy replenishment.

[0018] By means of the above technical solution, the present application provides a vehicle interior temperature control method and device based on multiple systems after leaving the vehicle. When it is necessary to control the temperature inside the vehicle after leaving the vehicle, the environmental information of the vehicle is acquired. The environmental information includes the interior temperature and the light intensity on the vehicle surface. The current cooling scenario of the vehicle is determined based on the interior temperature and the light intensity on the vehicle surface. If the cooling scenario is a high temperature cooling scenario, the vehicle is controlled to perform corresponding temperature control operations according to the first cooling strategy. The first cooling strategy is a dynamic collaborative control strategy based on ventilation and sunshade. If the cooling scenario is an ultra-high temperature cooling scenario, the vehicle is controlled to perform corresponding temperature control operations according to the second cooling strategy. The second cooling strategy is a dynamic collaborative control strategy based on cooling, sunshade and energy replenishment.

[0025] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0026] Currently, most existing methods for controlling the interior temperature after the vehicle leaves rely on a single temperature sensor to determine whether to activate the air conditioning system, thus regulating the interior temperature through the vehicle's built-in air conditioning system. While this method can control the interior temperature, it does not take into account the differentiated processing under different temperature conditions and lacks comprehensive consideration of external environmental factors such as light intensity. As a result, the interior temperature control effect is poor under extreme high temperature conditions, leading to a poor user experience.

[0027] Through research, the inventors discovered that different cooling scenarios can be set based on varying temperatures and light intensities, namely high-temperature cooling scenarios and ultra-high-temperature cooling scenarios. For each cooling scenario, different cooling strategies are set based on multiple temperature-related systems in the vehicle, such as the air conditioning system, sunshade system, and sunroof system. Once the cooling scenario is determined, multiple systems are dynamically and collaboratively controlled according to the corresponding cooling strategy. This allows for a more comprehensive assessment of the vehicle's environmental conditions by considering different temperature conditions and external environmental factors, accurately determining the cooling scenario and selecting the appropriate cooling strategy, thus improving the accuracy and effectiveness of temperature control and enhancing the user experience.

[0028] Based on the above considerations, this application provides a multi-system-based in-vehicle temperature control method after the user leaves the vehicle. This method comprehensively considers temperature differences and external environmental factors to improve the effectiveness of in-vehicle temperature control and enhance the user experience. The specific execution steps are as follows: Figure 1 As shown, it includes at least 101-104.

[0029] 101. Obtain vehicle environmental information.

[0030] The environmental information includes the vehicle interior temperature and the intensity of light on the vehicle surface.

[0031] In this step, temperature sensors are pre-installed at multiple locations inside the vehicle, such as the driver's seat, front passenger seat, and rear seats, to comprehensively monitor the temperature in various areas of the vehicle. These sensors collect real-time temperature data and transmit it to the vehicle's control system. Simultaneously, light intensity sensors are pre-installed on the vehicle's roof or near the windshield to detect the intensity of sunlight reaching the vehicle's surface. These sensors monitor solar radiation intensity in real-time and transmit the light intensity data to the control system, thus providing the vehicle with environmental information.

[0032] 102. Determine the current cooling scenario of the vehicle based on the interior temperature and the intensity of light on the vehicle surface.

[0033] Among them, the scenarios awaiting cooling include high-temperature scenarios awaiting cooling and ultra-high-temperature scenarios awaiting cooling.

[0034] In this step, based on the obtained in-vehicle temperature and surface light intensity, the current cooling scenario of the vehicle can be determined. Specifically, a set of temperature thresholds and light intensity thresholds can be preset. The real-time collected vehicle interior temperature and vehicle surface light intensity are compared with their respective thresholds. If the vehicle interior temperature exceeds the preset temperature threshold, the vehicle is determined to be in a high-temperature cooling scenario. If both the vehicle interior temperature and the vehicle surface light intensity exceed the preset light intensity threshold, the vehicle is determined to be in an extremely high-temperature cooling scenario. Multiple sets of temperature thresholds and light intensity thresholds can also be preset to correspond to different cooling scenarios. For example, high temperature corresponds to the first temperature threshold and the second light intensity threshold, and extremely high temperature corresponds to the second temperature threshold and the second light intensity threshold. When the real-time collected vehicle interior temperature and vehicle surface light intensity are compared with the thresholds of each set, if both the vehicle interior temperature and the vehicle surface light intensity exceed the preset first temperature threshold, the vehicle is determined to be in a high-temperature cooling scenario. If both the vehicle interior temperature and the vehicle surface light intensity exceed the preset second temperature threshold, the vehicle is determined to be in an extremely high-temperature cooling scenario. This embodiment does not limit the specifics of these thresholds.

[0035] The temperature threshold and the light intensity threshold can be customized by the user based on their vehicle usage needs, or they can be dynamically adjusted based on the weather conditions of the vehicle's location. For example, the vehicle's current location can be obtained through the vehicle's GPS, and real-time weather information for the area, including temperature and light intensity data, can be obtained from the cloud. The average temperature, rate of temperature change, average light intensity, and rate of change of light intensity for the area can be calculated, thereby dynamically adjusting the temperature threshold and light intensity threshold to adapt to different environmental conditions.

[0036] When the scenario to be cooled is determined to be a high temperature scenario, proceed to step 103; when the scenario to be cooled is determined to be an ultra-high temperature scenario, proceed to step 104.

[0037] 103. Control the vehicle to perform the corresponding temperature control operation according to the first cooling strategy.

[0038] The first cooling strategy is a dynamic, coordinated control strategy based on ventilation and shading.

[0039] Due to the trend towards vehicle intelligence, most vehicles are equipped with multiple intelligent systems to achieve various functions. Among these, systems related to temperature control include, but are not limited to, air conditioning systems, sunshade systems, and solar awning systems. Therefore, for the high-temperature cooling scenario in this step, a corresponding cooling strategy can be set based on these multiple systems, namely the first cooling strategy. Since the interior temperature is high but not yet extremely high in this scenario, the primary goal is to lower the interior temperature through ventilation and sunshade to prevent further increases. Introducing cooler outside air through external circulation mode, combined with closing the electric sunshade, can effectively lower the interior temperature while achieving a good balance between energy consumption and cooling effect. Therefore, in this step, cooling can be achieved primarily by controlling ventilation and sunshade in synergy. Specifically, the air conditioning system is activated, set to external circulation mode, and the fan speed and duration are set, such as running at medium speed for half an hour. External circulation mode effectively introduces cooler outside air, lowering the interior temperature. At the same time, the electric sunshade is closed to block direct sunlight, thereby reducing the amount of external heat entering the vehicle and lowering the interior temperature.

[0040] In addition, to ensure the effectiveness and accuracy of the primary cooling strategy for high-temperature scenarios requiring cooling, the system can monitor and analyze the changing trend of the single execution duration in these scenarios and dynamically adjust the air conditioning system's fan speed settings. For example, if it is found that the single execution duration of a high-temperature scenario requiring cooling gradually increases over a certain period, the system can appropriately increase the fan speed to accelerate the cooling process.

[0041] 104. Control the vehicle to perform the corresponding temperature control operation according to the second cooling strategy.

[0042] The second cooling strategy is a dynamic coordinated control strategy based on cooling, shading, and energy replenishment.

[0043] Based on the description of the temperature control-related systems in the vehicle in step 103, a corresponding cooling strategy can also be set based on the above multiple systems for the ultra-high temperature cooling scenario in this step, namely the second cooling strategy.

[0044] In extreme heat scenarios requiring cooling, the interior temperature is very high, and the intensity of sunlight on the vehicle surface is also very strong. Therefore, the primary goal is to rapidly reduce the interior temperature to ensure the environment returns to a comfortable state as quickly as possible. Compared to high-temperature cooling scenarios, relying solely on external air circulation may not be sufficient to quickly lower the interior temperature. More robust cooling measures are needed, such as internal air circulation, higher fan speed, and adjusting the solar sunroof to its lowest possible transmittance. These extreme conditions require more energy for rapid cooling. In addition to using the air conditioning's internal circulation mode and high fan speed, the solar sunroof system can be used to charge the battery, ensuring sufficient energy to support the air conditioning system's prolonged operation. Therefore, in this step, cooling can be achieved primarily through the coordinated control of cooling, sunshade, and energy replenishment. This involves starting the air conditioning system, setting it to internal circulation mode, and configuring the temperature, fan speed, and duration of the internal circulation mode, such as running at a lower temperature and high fan speed for half an hour. Internal circulation mode quickly lowers the interior temperature, while the higher fan speed helps accelerate airflow and improve cooling efficiency. Furthermore, the electric sunshade can be closed to block direct sunlight, further reducing external heat entering the vehicle and thus lowering the interior temperature. Simultaneously, the solar sunroof's color can be adjusted to its lowest light transmittance to maximize sunlight reflection, reducing heat absorption inside the vehicle. Moreover, if the battery's remaining charge is insufficient, the solar sunroof can be used to charge the battery, utilizing solar energy to improve energy efficiency.

[0045] In addition, to ensure the effectiveness and accuracy of the second cooling strategy for ultra-high temperature scenarios, the cumulative number of executions of the ultra-high temperature scenario can be monitored and analyzed. A preset threshold range can be used for comparison, and the temperature and fan speed settings of the air conditioning system can be adjusted accordingly. For example, if it is found that the cumulative number of executions of the ultra-high temperature scenario is high within a certain period, the system can appropriately lower the temperature or increase the fan speed to enhance the cooling effect.

[0046] Based on the above Figure 1As can be seen from the implementation method, the in-vehicle temperature control method based on multiple systems provided in this application obtains the vehicle's environmental information when it is necessary to control the temperature inside the vehicle after leaving the vehicle. The environmental information includes the in-vehicle temperature and the light intensity on the vehicle surface. Based on the in-vehicle temperature and the light intensity on the vehicle surface, the current cooling scenario of the vehicle is determined. If the cooling scenario is a high-temperature cooling scenario, the vehicle is controlled to perform corresponding temperature control operations according to the first cooling strategy. The first cooling strategy is a dynamic collaborative control strategy based on ventilation and sunshade. If the cooling scenario is an ultra-high-temperature cooling scenario, the vehicle is controlled to perform corresponding temperature control operations according to the second cooling strategy. The second cooling strategy is a dynamic collaborative control strategy based on cooling, sunshade, and energy replenishment. The technical solution provided in this application enables a more comprehensive assessment of the vehicle's environmental conditions based on the interior temperature and surface light intensity. This allows for accurate identification of high or ultra-high temperature scenarios requiring cooling, and the selection of appropriate cooling strategies based on these scenarios. Temperature control is achieved through the coordinated and dynamic adjustment of multiple systems, including the vehicle's air conditioning, sunshade, and panoramic sunroof systems, improving the accuracy and effectiveness of temperature control and enhancing the user experience. Furthermore, by implementing different cooling strategies for different scenarios, the vehicle's temperature control process becomes more targeted, effectively reducing energy consumption.

[0047] Furthermore, the preferred embodiments of this application are based on the above... Figure 1 Based on this, a detailed explanation of the multi-system in-vehicle temperature control process after the driver leaves the vehicle is provided. The specific steps are as follows: Figure 2 As shown, this includes 201-207.

[0048] 201. Obtain the vehicle's environmental information.

[0049] This step combines the description of step 101 in the above method, and the same content will not be repeated here.

[0050] 202. Obtain the preset temperature threshold and light intensity threshold.

[0051] Among them, the temperature threshold and light intensity threshold are dynamically adjusted according to the meteorological conditions at the vehicle's location.

[0052] In this step, an initial set of temperature and light intensity thresholds can be pre-set based on the user's desired comfortable temperature during vehicle use. For example, the temperature threshold could be 18 degrees Celsius, 20 degrees Celsius, etc., and the light intensity threshold could be 40,000 lux, 50,000 lux, etc. Since in-vehicle temperature changes are affected by external environmental factors, including air temperature and light intensity, and these vary depending on the location, the initial temperature and light intensity thresholds can also be adjusted based on meteorological information of the vehicle's location to adapt to different environmental conditions.

[0053] Regarding the above description of temperature thresholds and light thresholds based on meteorological information, the specific execution process is as follows: obtain meteorological information corresponding to the vehicle's location; determine the average temperature and temperature change rate based on the temperature information, and dynamically adjust the temperature threshold based on the average temperature and temperature change rate; determine the average light intensity and light intensity change rate based on the light intensity information, and dynamically adjust the light intensity threshold based on the average light intensity and light intensity change rate.

[0054] The meteorological information includes temperature and light intensity information. Real-time meteorological information about the vehicle's location can be obtained from the cloud via the internet or an in-vehicle communication module (such as a TBOX). Based on the obtained meteorological information, the average temperature and the rate of temperature change at that location are calculated. The average temperature reflects the overall temperature level at that location, while the rate of temperature change reflects the trend of temperature change. The temperature threshold is dynamically adjusted based on the calculated average temperature and rate of temperature change. For example, if the average temperature at that location is high and the rate of change is rapid, the temperature threshold can be appropriately increased. Specifically, a temperature adjustment gradient, such as 1 degree or 2 degrees, can be set to adapt to high-temperature environments. Similarly, the average light intensity and the rate of light intensity change at that location are calculated. The average light intensity reflects the overall light level of the area, while the rate of light intensity change reflects the trend of light intensity change. The light intensity threshold is dynamically adjusted based on the calculated average light intensity and rate of light intensity change. For example, if the average light intensity in the area is high and changes rapidly, the light intensity threshold can be appropriately increased. Specifically, a slight adjustment gradient for light intensity can be set, such as 10,000 lux or 15,000 lux, to adapt to strong light environments. This dynamic adjustment method makes the subsequent judgment process for cooling scenarios more accurate.

[0055] Since the interior temperature of a vehicle can rise even under moderate light intensity due to other factors (such as high external ambient temperature and heat dissipation from internal vehicle equipment), it is only necessary to monitor whether the interior temperature exceeds the temperature threshold to determine whether a cooling strategy is needed. This eliminates the need to consider the impact of light intensity on the interior temperature, thus improving the sensitivity in identifying high-temperature scenarios requiring cooling. Strong sunlight significantly increases heat accumulation inside the vehicle, causing the interior temperature to rise rapidly. When the surface light intensity also exceeds the light intensity threshold, it indicates that not only is the interior temperature high, but the external light intensity is also very strong. In this case, a more aggressive cooling strategy is needed, ensuring the accuracy of identifying extremely high-temperature scenarios requiring cooling. Therefore, in this step, by comparison, if the interior temperature exceeds the temperature threshold, step 203 is executed; if both the interior temperature and the surface light intensity exceed the light intensity threshold, step 204 is executed.

[0056] By setting different judgment criteria, more accurate and effective temperature control solutions can be provided under different environmental conditions. In high-temperature scenarios requiring cooling, focusing solely on the vehicle's interior temperature can effectively reduce energy consumption, while in ultra-high-temperature scenarios requiring cooling, comprehensively considering both the vehicle's interior temperature and the intensity of light on the vehicle's surface can ensure rapid cooling and improve the user experience. This layered strategy design can flexibly respond to various environmental conditions and provide optimal temperature control performance.

[0057] 203. Determine that the vehicle is currently in a high-temperature waiting-to-cool-down scenario.

[0058] In this step, if it is determined that the vehicle is currently in a high-temperature waiting-to-cool-down scenario, then step 205 is executed.

[0059] 204. Determine that the vehicle is currently in an extremely high temperature scenario and needs to cool down.

[0060] In this step, if it is determined that the vehicle is currently in an ultra-high temperature cooling scenario, then step 206 is executed.

[0061] 205. Control the vehicle's electric sunshade system to switch to the closed state, and control the vehicle's air conditioning system to operate in external circulation mode at the first preset fan speed for a preset time.

[0062] In this step, the preset duration and first preset fan speed can be customized according to usage needs. The fan speed selection can be determined based on the specific vehicle model and the performance of the air conditioning system; it can be set to medium speed, and the duration can be set to 30 minutes. By running the external circulation mode at the first preset fan speed for the preset duration, cooler outside air is continuously introduced, and the electric sunshade is closed, effectively blocking direct sunlight and preventing external heat from entering the vehicle, thereby effectively lowering the interior temperature.

[0063] To ensure the accuracy and effectiveness of the first cooling strategy, during this step, the following can also be done: obtain the duration of a single execution for the high-temperature scenario to be cooled within a specified period; statistically analyze the trend of the single execution duration; and update the first preset wind speed based on the trend.

[0064] It's important to note that the determination of the high-temperature cooling scenario and the subsequent execution of the first cooling strategy are typically recorded. Since there's a hierarchical relationship between the high-temperature and ultra-high-temperature cooling scenarios, the difference in their determination lies in whether the vehicle surface light intensity exceeds a certain threshold. If the vehicle surface light intensity exceeds this threshold during the execution of the first cooling strategy, it's necessary to switch from the high-temperature cooling scenario to the ultra-high-temperature cooling scenario. In other words, the duration of a single execution in the high-temperature cooling scenario varies. Statistical analysis of this duration can reflect the effectiveness of the first cooling strategy. The first cooling strategy primarily involves the air conditioning system operating in external circulation mode, and the factor affecting the effectiveness of this mode is the first preset fan speed. Therefore, the trend of the single execution duration can be periodically analyzed, for example, every 24 hours, and the first preset fan speed can be dynamically adjusted based on this trend. For example, a wind speed adjustment gradient can be set, which can be a gear gradient or a specific level gradient. If the duration of a single execution gradually increases, the wind speed can be appropriately increased according to the adjustment gradient to speed up the cooling process. Conversely, if the duration of a single execution gradually decreases, the wind speed can be appropriately decreased according to the adjustment gradient to save energy.

[0065] 206. Control the vehicle's air conditioning system to operate in recirculation mode at a preset temperature and a second preset fan speed for a preset time period, control the vehicle's electric sunshade system to switch to the closed state, and control the vehicle's solar sunroof system to adjust the sunroof color to the lowest light transmittance.

[0066] In this step, the preset duration, preset temperature, and second preset fan speed can be customized according to usage needs. The preset temperature is lower than the aforementioned temperature threshold to ensure the air conditioning system is in cooling mode. Similarly, the fan speed selection can be determined based on the specific vehicle model and the performance of the air conditioning system; it can be set to a high fan speed, and the duration can be set to 30 minutes. By running the internal circulation mode at the preset temperature and second preset fan speed for the preset duration, the vehicle can be cooled and the cool air circulated. Closing the electric sunshade and adjusting the solar sunroof to its lowest light transmittance effectively blocks direct sunlight, maximizes the reflection of sunlight, reduces the absorption of heat inside the vehicle, and reduces the amount of external heat entering the vehicle, thereby lowering the interior temperature.

[0067] To ensure the accuracy and effectiveness of the second cooling strategy, the following steps can be taken during execution: The cumulative number of executions for the ultra-high temperature cooling scenario within a specified period can be obtained; the cumulative number of executions can be compared with a preset threshold range, and the preset temperature and / or the second preset wind speed can be updated based on the comparison results.

[0068] It should be noted that the determination of the ultra-high temperature cooling scenario and the subsequent execution of the second cooling strategy will also have corresponding execution records. Since the ultra-high temperature cooling scenario transitions from the high temperature cooling scenario, it means that the ultra-high temperature cooling scenario will only be entered under continuous strong sunlight and high temperature. Therefore, the fewer times the ultra-high temperature cooling scenario is entered, the more effective the second cooling strategy is. In other words, the cumulative number of executions corresponding to the ultra-high temperature cooling scenario reflects the effectiveness of the second cooling strategy. Therefore, the trend of the cumulative execution count can be periodically analyzed, for example, every 24 hours, and the preset temperature and / or the second preset wind speed can be dynamically adjusted based on the trend of the cumulative execution count. For example, a temperature adjustment gradient or a wind speed adjustment gradient can be set. The temperature adjustment gradient can be 1 degree or 2 degrees, and the wind speed adjustment gradient can be a gear gradient or a specific level gradient. If the cumulative number of executions is high, the preset temperature can be appropriately lowered according to the temperature adjustment gradient or the wind speed can be appropriately increased according to the wind speed adjustment gradient to enhance the cooling effect. Conversely, if the cumulative number of executions is low, the preset temperature can be appropriately raised according to the temperature adjustment gradient or the wind speed can be appropriately lowered according to the wind speed adjustment gradient to save energy.

[0069] 207. If the battery charge of the vehicle's power battery does not reach the preset battery charge threshold, the vehicle's solar sunroof system will be controlled to charge the power battery at a preset power within a preset time.

[0070] In this step, since the solar canopy's color was adjusted to its lowest light transmittance in step 206, further utilization of solar energy is achieved under strong direct sunlight, thus providing more sufficient energy for the air conditioning system. At this point, the battery management system can obtain real-time battery charge data and pre-set a battery charge threshold to determine if the battery is sufficiently charged, for example, at 80%. If sufficient, no additional charging is needed; if insufficient, the solar canopy system can charge the battery at a preset power for a preset time period, such as 20 minutes, and the preset power can be determined based on the solar canopy's performance and the battery's charging needs. Simultaneously, the battery management system monitors the charging status in real-time to ensure the battery charge reaches the preset threshold, maintaining stable battery charge during cooling and improving energy efficiency.

[0071] Furthermore, since the vehicle usage scenario in this embodiment is after leaving the vehicle, in order to improve the system's intelligence level and user experience, during the execution of steps 201-207, the following can also be done: monitor the execution status of the first cooling strategy or the second cooling strategy; generate cooling feedback information based on the execution status to provide real-time notifications to the user about the temperature control status inside the vehicle.

[0072] In this step, the current status of the sunshade (open or closed) is obtained through the electric sunshade controller, the current operating mode (external or internal circulation), fan speed setting, and temperature setting of the air conditioning system are obtained through the air conditioning controller, the current color (transmittance) and charging status of the solar sunroof are obtained through the solar sunroof controller, and the current battery charge is obtained through the battery management system. The status of each system can be checked periodically (e.g., every 5 minutes) to ensure data real-time performance and accuracy, and to detect any system malfunctions or abnormalities, such as the electric sunshade failing to close properly or the air conditioning system failing to start. The acquired system status data is integrated into a comprehensive status report, including information on the electric sunshade status, air conditioning system status, solar sunroof status, and battery charge. This report, combined with changes in the vehicle's interior temperature, generates cooling feedback information to provide real-time updates on the vehicle's temperature control. Specifically, this information is formatted into easily understandable text, such as: "Current interior temperature: 28℃, Electric sunshade: Closed, Air conditioning mode: External circulation, Fan speed: Medium, Solar sunroof: Lowest transmittance, Battery charge: 85%." It can also generate graphical interfaces that include the above information, such as a dashboard displaying the current temperature, a sunshade icon displaying the status, an air conditioner icon displaying the mode and fan speed, etc.

[0073] The generated cooling feedback information is sent to the user's mobile app via TBOX (Intelligent Connectivity System), and a notification is pushed to the user's app to ensure that the user can understand the temperature control status inside the vehicle in real time. If any fault or abnormality is detected in any system, an abnormality alarm message is immediately generated and sent to the user's app via TBOX.

[0074] Furthermore, as a response to the above Figure 1-2 The implementation of the method embodiment shown in this application provides a multi-system-based in-vehicle temperature control device after the user leaves the vehicle. This device comprehensively considers temperature differences and external environmental factors to improve the effectiveness of in-vehicle temperature control and enhance the user experience. The embodiment of this device corresponds to the aforementioned method embodiment. For ease of reading, this embodiment will not repeat the details of the aforementioned method embodiment, but it should be understood that the device in this embodiment can implement all the contents of the aforementioned method embodiment. Specifically, as shown... Figure 3 As shown, the device includes:

[0075] Acquisition unit 31 is used to acquire environmental information of the vehicle, including the vehicle interior temperature and the vehicle surface light intensity;

[0076] The determining unit 32 is used to determine the current cooling scenario of the vehicle based on the vehicle interior temperature and the vehicle surface light intensity obtained by the acquiring unit 31.

[0077] The first processing unit 33 is configured to control the vehicle to perform corresponding temperature control operations according to the first cooling strategy if the determining unit 32 confirms that the cooling scenario is the high temperature cooling scenario.
