[0025] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0026] At present, the existing in-car temperature control after leaving the vehicle mostly relies on a single temperature sensor to determine whether to start the air conditioning system, so as to adjust the temperature in the car through the air conditioning system equipped in the vehicle. Although this method can control the temperature in the car, 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, resulting in poor in-car temperature control effect and poor user experience under extreme high temperature conditions.

[0027] After research, the inventor found that different cooling scenes can be set in combination with different temperatures and light intensities, namely high-temperature cooling scenes and ultra-high-temperature cooling scenes. Different cooling strategies can be set for different cooling scenes based on the air-conditioning system, sunshade system, skylight system and other systems related to temperature control in the vehicle. After determining the cooling scene, the temperature control of multiple systems can be dynamically coordinated according to the corresponding cooling strategy. In this way, the environmental conditions of the vehicle can be more comprehensively evaluated by considering different temperature conditions and external environmental factors, so as to accurately determine the cooling scene and select the appropriate cooling strategy to execute, thereby improving the accuracy and effectiveness of temperature control and enhancing the user experience.

[0028] Based on the above considerations, the embodiment of the present application provides a method for in-vehicle temperature control based on multiple systems after leaving the vehicle. This method can comprehensively consider the differences in temperature conditions and factors outside the vehicle environment, improve the effect of in-vehicle temperature control, and enhance user experience. The specific execution steps are as follows: Figure 1 As shown, at least 101-104 are included.

[0029] 101. Obtain vehicle environmental information.

[0030] Among them, environmental information includes the temperature inside the car and the light intensity on the car surface.

[0031] In this step, temperature sensors are installed in multiple locations in the car, such as the driver's seat, the co-pilot seat, the back seat, etc., to comprehensively monitor the temperature of each area in the car. The temperature sensor collects the temperature data in the car in real time and transmits it to the body controller. At the same time, a light intensity sensor is installed on the top of the vehicle or near the front windshield to detect the light intensity received by the vehicle. The light intensity sensor can monitor the intensity of solar radiation in real time and transmit the light intensity data to the body controller. Thus, the vehicle obtains environmental information.

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

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

[0034] In this step, the current cooling scenario of the vehicle can be comprehensively determined based on the acquired vehicle interior temperature and vehicle surface light intensity. Specifically, a set of temperature thresholds and light intensity thresholds can be pre-set, and the real-time collected in-vehicle temperature and vehicle surface light intensity are compared with their respective thresholds. If the in-vehicle temperature exceeds the preset temperature threshold, it is judged that the vehicle is currently in a high temperature waiting to be cooled down scene. If the in-vehicle temperature exceeds the preset temperature threshold and the vehicle surface light intensity exceeds the preset light intensity threshold, it is judged that the vehicle is currently in an ultra-high temperature waiting to be cooled down scene. Multiple sets of temperature thresholds and light intensity thresholds can also be pre-set to correspond to different cooling down scenes, such as high temperature corresponding to a first temperature threshold and a second light intensity threshold, and ultra-high temperature corresponding to a second temperature threshold and a second light intensity threshold. When the real-time collected in-vehicle temperature and vehicle surface light intensity are compared with the thresholds of each group, if the in-vehicle temperature exceeds the preset first temperature threshold and the vehicle surface light intensity exceeds the preset first light intensity threshold, it is judged that the vehicle is currently in a high temperature waiting to be cooled down scene. If the in-vehicle temperature exceeds the preset second temperature threshold and the vehicle surface light intensity exceeds the preset second light intensity threshold, it is judged that the vehicle is currently in an ultra-high temperature waiting to be cooled down scene. This embodiment does not limit this.

[0035] The temperature threshold and the light intensity threshold can be customized by the user based on the vehicle usage requirements, and can also be dynamically adjusted based on the meteorological conditions at the vehicle's location. For example, the vehicle's current location is obtained through the on-board GPS, and real-time meteorological information of the area is obtained from the cloud, including temperature and light intensity data, and the average temperature, temperature change rate, average light intensity, light intensity change rate, etc. of the area are calculated, so as to dynamically adjust the temperature threshold and the light intensity threshold to adapt to different environmental conditions.

[0036] When it is determined that the scene to be cooled is a high-temperature scene to be cooled, step 103 is executed; when it is determined that the scene to be cooled is an ultra-high-temperature scene to be cooled, step 104 is executed.

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

[0038] Among them, the first cooling strategy is a dynamic collaborative control strategy based on ventilation and shading.

[0039] Due to the trend of intelligent vehicles, most of them are equipped with multiple intelligent systems to achieve multiple functions, and the systems related to temperature control include but are not limited to air conditioning systems, sunshade systems, solar canopy systems, etc. Therefore, for the high temperature cooling scene in this step, a corresponding cooling strategy can be set based on the above multiple systems, that is, the first cooling strategy. Because in the high temperature cooling scene, the temperature inside the car is high, but has not reached an extreme high temperature, that is, the main goal at this time is to reduce the temperature inside the car through ventilation and shading to prevent the temperature from continuing to rise. The introduction of cooler air from the outside through the external circulation mode, combined with the closing of the electric sunshade, can effectively reduce the temperature inside the car, and a good balance is achieved between energy consumption and cooling effect. Therefore, in this step, cooling can be achieved mainly by controlling ventilation and shading. That is, start the air conditioning system, set it to the external circulation mode, and set the wind speed and running time of the external circulation mode, such as running at a medium wind speed for half an hour, etc., and the external circulation mode can effectively introduce cooler air from the outside to reduce the temperature inside the car. At the same time, the electric sunshade is controlled to close to block direct sunlight, so as to reduce the external heat entering the car and thus lower the temperature inside the car.

[0040] In addition, in order to ensure the effectiveness and accuracy of the first cooling strategy for high-temperature cooling scenarios, the changing trend of the single execution time in the high-temperature cooling scenario can be monitored and analyzed, and the wind speed setting of the air-conditioning system can be dynamically adjusted. For example, if it is found that the single execution time of the high-temperature cooling scenario gradually increases over a period of time, the system can appropriately increase the wind speed to speed up the cooling speed.

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

[0042] Among them, the second cooling strategy is a dynamic collaborative control strategy based on refrigeration, shading and energy replenishment.

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

[0044] Since the temperature inside the car is very high and the light intensity on the car surface is also very strong in the ultra-high temperature cooling scenario, the main goal at this time is to quickly reduce the temperature inside the car and ensure that the interior environment returns to a comfortable state as soon as possible. Compared with the high temperature cooling scenario, the external circulation mode alone may not be able to quickly reduce the temperature inside the car. Stronger cooling measures are needed, such as the internal circulation mode, higher wind speed, and the minimum transmittance adjustment of the solar canopy to achieve rapid cooling. In addition to using the air conditioning internal circulation mode and high wind speed, the solar canopy system can also be used to charge the power battery to ensure that there is enough energy to support the air conditioning system to run for a long time. Therefore, in this step, cooling can be achieved mainly by controlling refrigeration, shading and energy replenishment. That is, the air conditioning system is started, set to the internal circulation mode, and the temperature, wind speed and running time of the internal circulation mode are set, such as running at a lower temperature and high wind speed for half an hour, and the internal circulation mode can quickly reduce the temperature inside the car, while the higher wind speed helps to speed up air flow and improve cooling efficiency. In addition, the electric sunshade is controlled to close to block direct sunlight, further reducing the external heat entering the car, thereby reducing the temperature inside the car. At the same time, the color of the solar skylight is controlled to be adjusted to the lowest light transmittance to maximize the reflection of sunlight and reduce the temperature absorption inside the car. If the remaining power of the power battery is insufficient, the solar skylight can also be controlled to charge the power battery, using solar energy resources to improve energy utilization efficiency.

[0045] In addition, in order to ensure the effectiveness and accuracy of the second cooling strategy for the ultra-high temperature cooling scene, the cumulative execution times of the ultra-high temperature cooling scene can also be monitored and analyzed, and a threshold range of times can be preset for comparison, so as to adjust the temperature and wind speed settings of the air conditioning system. For example, if it is found that the cumulative execution times of the ultra-high temperature cooling scene are large within a certain period of time, the system can appropriately reduce the temperature or increase the wind speed to enhance the cooling effect.

[0046] Based on the above Figure 1It can be seen from the implementation method that the present application provides a method for in-vehicle temperature control based on multiple systems after leaving the vehicle. When the temperature in the vehicle needs to be controlled after leaving the vehicle, the vehicle's environmental information is obtained, the environmental information including the in-vehicle temperature and the vehicle surface light intensity. The vehicle's current cooling scene is determined according to the in-vehicle temperature and the vehicle surface light intensity. If the cooling scene is a high-temperature cooling scene, the vehicle is controlled to perform corresponding temperature control operations according to the first cooling strategy, which is a dynamic collaborative control strategy based on ventilation and shading. If the cooling scene is an ultra-high-temperature cooling scene, the vehicle is controlled to perform corresponding temperature control operations according to the second cooling strategy, which is a dynamic collaborative control strategy based on refrigeration, shading and energy replenishment. Through the technical solution provided by this application, the environmental conditions of the vehicle can be more comprehensively evaluated based on the temperature inside the vehicle and the light intensity on the vehicle surface, that is, the vehicle can be accurately judged to be in a high temperature or ultra-high temperature cooling scene, and the appropriate cooling strategy can be selected according to different cooling scenes, so as to achieve temperature control through the coordinated dynamic adjustment of multiple systems such as the air conditioning system, sunshade system, and skylight system equipped in the vehicle, thereby improving the accuracy and effectiveness of temperature control and enhancing the user experience. In addition, by executing different cooling strategies corresponding to different cooling scenes, the temperature control process inside the vehicle can also be made more targeted, effectively reducing the energy consumption of the temperature control process.

[0047] Further, the preferred embodiment of the present application is in the above Figure 1 Based on the above, a detailed description of the process of temperature control in the car based on multiple systems after leaving the car is given. The specific steps are as follows Figure 2 As shown, including 201-207.

[0048] 201. Obtain environmental information of the vehicle.

[0049] This step is combined with the description of step 101 in the above method, and the same contents will not be repeated here.

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

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

[0052] In this step, a set of initial temperature thresholds and light intensity thresholds can be set in advance according to the user's requirements for comfortable temperature during the use of the vehicle. For example, the temperature threshold can be 18 degrees, 20 degrees, etc., and the light intensity threshold can be 40,000 lux, 50,000 lux, etc. Since the temperature change inside the vehicle is affected by external environmental factors, including air temperature and light intensity, and the corresponding air temperature and light intensity at different locations are also different, the initial temperature threshold and light intensity threshold can also be adjusted in combination with the meteorological information at the location of the vehicle to adapt to different environmental conditions.

[0053] Regarding the above description of temperature threshold and light threshold in combination with meteorological information, the specific implementation process is: 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] Among them, meteorological information includes temperature information and light intensity information. Real-time meteorological information of the vehicle's location can be obtained from the cloud through the Internet or a vehicle-mounted communication module (such as TBOX). According to the obtained meteorological information, the average temperature and temperature change rate of the location are calculated. The average temperature reflects the overall temperature level of the location, while the temperature change rate reflects the trend of temperature change. According to the calculated average temperature and temperature change rate, the temperature threshold is dynamically adjusted. For example, if the average temperature of the location is high and the change rate is fast, the temperature threshold can be appropriately increased. Specifically, a temperature adjustment gradient can be set, such as 1 degree, 2 degrees, etc., to adapt to the high temperature environment. Similarly, the average light intensity and light intensity change rate of the location are calculated. The average light intensity reflects the overall light level of the area, while the light intensity change rate reflects the trend of light intensity change. According to the calculated average light intensity and light intensity change rate, the light intensity threshold is dynamically adjusted. 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 light adjustment gradient can be set, such as 10,000 lux, 15,000 lux, etc., to adapt to strong light environments. This dynamic adjustment makes the subsequent judgment process of the cooling scene more accurate.

[0055] Since the temperature inside the car may also rise due to other factors (such as high external ambient temperature, heat dissipation of internal vehicle equipment, etc.) when the light intensity is moderate, it is only necessary to pay attention to whether the temperature inside the car exceeds the temperature threshold to determine whether a cooling strategy needs to be adopted, that is, there is no need to pay attention to the impact of light intensity on the temperature inside the car, thereby improving the sensitivity of determining the high-temperature cooling scene. Strong light will significantly increase the heat accumulation inside the car, causing the temperature inside the car to rise rapidly. When the light intensity of the car surface also exceeds the light intensity threshold, it means that not only the temperature inside the car is high, but also the light intensity outside is sufficient. At this time, a stronger cooling strategy needs to be adopted to ensure the accuracy of determining the ultra-high temperature cooling scene. Therefore, in this step, by comparison, if the temperature inside the car exceeds the temperature threshold, step 203 is executed, and if the temperature inside the car exceeds the temperature threshold and the light intensity of the car surface exceeds 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 the high temperature cooling scenario, only focusing on the temperature inside the car can effectively reduce energy consumption, while in the ultra-high temperature cooling scenario, comprehensive consideration of the temperature inside the car and the light intensity on the car surface can ensure rapid cooling and improve user experience. This hierarchical strategy design can flexibly respond to various environmental conditions and provide the best temperature control effect.

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

[0058] In this step, when it is determined that the vehicle is currently in a high temperature to be cooled down scenario, step 205 is executed.

[0059] 204. Determine that the vehicle is currently in an extremely high temperature waiting to be cooled down scenario.

[0060] In this step, when it is determined that the vehicle is currently in an ultra-high temperature waiting to be cooled down scenario, step 206 is executed.

[0061] 205. Control the electric sunshade system of the vehicle to switch to a closed state, and control the air conditioning system of the vehicle to operate in an external circulation mode at a first preset wind speed within a preset time.

[0062] In this step, the preset duration and the first preset wind speed can be customized according to the use requirements. The wind speed can be determined according to the specific model of the vehicle and the performance of the air conditioning system. It can be set to a medium wind speed, and the duration can be set to 30 minutes. By running the external circulation mode at the first preset wind speed within the preset duration, continuously introducing cooler air from the outside, and closing the electric sunshade, it is possible to effectively block direct sunlight and external heat from entering the vehicle, thereby effectively reducing the temperature inside the vehicle.

[0063] In order to ensure the accuracy and effectiveness of the first cooling strategy, during the execution of this step, it is also possible to: obtain the single execution time corresponding to the high temperature cooling scene within the specified period; calculate the change trend corresponding to the single execution time, and update the first preset wind speed according to the change trend.

[0064] It should be noted that the determination of the high-temperature cooling scene and the subsequent execution of the first cooling strategy usually have corresponding execution records. Since there is a hierarchical relationship between the high-temperature cooling scene and the ultra-high-temperature cooling scene, the difference in the judgment of the two lies in whether the light intensity of the vehicle surface exceeds the light intensity threshold. If the light intensity of the vehicle surface exceeds the light intensity threshold during the execution of the first cooling strategy, it is necessary to switch from the high-temperature cooling scene to the ultra-high-temperature cooling scene. In other words, the single execution duration of the high-temperature cooling scene varies. By counting the changing trend of the single execution duration, it can be reflected whether the first cooling strategy is effective. The first cooling strategy is mainly the air-conditioning system running in the external circulation mode, and the factor affecting the effect of the external circulation mode is the first preset wind speed. Therefore, the changing trend of the single execution duration can be regularly counted, for example, once every 24 hours, and the first preset wind speed can be dynamically adjusted according to the changing trend. For example, a wind speed adjustment gradient is set, which can be a gear gradient or a specific level gradient. If the single execution time gradually increases, the wind speed can be appropriately increased according to the adjustment gradient to speed up the cooling speed. Conversely, if the single execution time gradually decreases, the wind speed can be appropriately reduced according to the adjustment gradient to save energy.

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

[0066] In this step, the preset duration, preset temperature and second preset wind speed can be customized according to the use requirements. The preset temperature is lower than the aforementioned temperature threshold so that the air conditioning system is in a cooling state. Similarly, the wind speed selection can be determined according to the specific model of the vehicle and the performance of the air conditioning system. It can be set to a high-end wind speed, and the duration can be set to 30 minutes. By running the internal circulation mode at the preset temperature and the second preset wind speed within the preset duration, the cold air can be refrigerated and circulated in the car, the electric sunshade is closed, and the color of the solar canopy is adjusted to the lowest light transmittance, which can effectively block direct sunlight, maximize the reflection of sunlight, reduce the temperature absorption in the car, and reduce the external heat entering the car, thereby reducing the temperature in the car.

[0067] In order to ensure the accuracy and effectiveness of the second cooling strategy, during the specific execution of this step, it is also possible to: obtain the cumulative execution times corresponding to the ultra-high temperature cooling scene within the specified period; compare the cumulative execution times with the preset times threshold range, and update the preset temperature and / or the second preset wind speed according to the comparison result.

[0068] It should be noted that the determination of the ultra-high temperature cooling scene and the subsequent execution of the second cooling strategy will also have corresponding execution records. Since the ultra-high temperature cooling scene is switched from the high temperature cooling scene, that is to say, the ultra-high temperature cooling scene will only be entered under continuous strong light exposure and high temperature, that is, the fewer times the ultra-high temperature cooling scene is entered, the more effective the second cooling strategy is, that is, the cumulative number of executions corresponding to the ultra-high temperature cooling scene reflects whether the second cooling strategy is effective. Therefore, the changing trend of the cumulative number of executions can be regularly counted, for example, once every 24 hours, and the preset temperature and / or the second preset wind speed can be dynamically adjusted according to the changing trend of the cumulative number of executions. For example, set a temperature adjustment gradient or a wind speed adjustment gradient. 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 large, 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 small, the preset temperature can be appropriately increased 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 power corresponding to the power battery of the vehicle does not reach the preset battery power threshold, the solar skylight system of the vehicle is controlled to charge the power battery at a preset power within a preset time.

[0070] In this step, since the color of the solar canopy has been adjusted to the lowest transmittance in step 206. In order to further utilize light energy under strong direct sunlight, more sufficient energy is provided for the air conditioning system. At this time, the power data of the power battery can be obtained in real time from the battery management system, and a battery power threshold is pre-set to determine whether the power of the power battery is sufficient, for example, 80%. If it is sufficient, no additional charging is required. If it is not sufficient, the solar canopy system can be controlled to charge the power battery at a preset power within a preset time. The preset time can be set to 20 minutes, and the preset power can be determined according to the performance of the solar canopy and the charging requirements of the battery. At the same time, the charging status is monitored in real time by the battery management system to ensure that the battery power reaches the preset threshold, that is, the stability of the power battery power is maintained during the cooling process to improve energy utilization.

[0071] Furthermore, since the vehicle usage scenario of this embodiment is after leaving the vehicle, in order to improve the intelligence level of the system and user experience, during the execution of steps 201-207, it is also possible to: monitor the execution status of the first cooling strategy or the second cooling strategy; generate cooling feedback information based on the execution status to prompt the user of the temperature control status in the car in real time.

[0072] In this step, the current state of the sunshade (open or closed) is obtained through the electric sunshade controller, the current operating mode (external circulation or internal circulation), wind speed setting, temperature setting and other information of the air conditioning system are obtained through the air conditioning controller, the current color (transmittance) and charging status of the sunshade are obtained through the solar sunshade controller, and the current power of the power battery is obtained through the battery management system. The status of the above systems can be checked at regular intervals (for example, every 5 minutes) to ensure the real-time and accuracy of the data, and to detect whether any system has a fault or abnormality, such as the electric sunshade cannot be closed normally, the air conditioning system cannot be started, etc. The obtained system status data is integrated into a comprehensive status report, including information such as the electric sunshade status, the air conditioning system status, the solar sunshade status and the battery power, and the cooling feedback information is generated in combination with the temperature change in the car to prompt the user of the temperature control situation in the car in real time. Specifically, the above information is formatted into easy-to-understand text information, for example: "Current car temperature: 28°C, electric sunshade: closed, air conditioning mode: external circulation, wind speed: medium speed, solar sunshade: minimum transmittance, battery power: 85%".
