[0002] With the continuous development of the automotive industry, the comfort of the car cabin has become one of the core indicators affecting the passenger experience. Furthermore, with the rapid improvement in the level of vehicle intelligence, passengers are placing higher demands on the airflow distribution of the vehicle's air conditioning system.

[0003] In related technologies, vehicles default to opening only the face air vent in summer conditions, and similarly, vehicles default to opening only the foot air vent in winter conditions. In spring and autumn conditions, the face air vent and foot air vent are opened according to a fixed air volume ratio.

[0004] However, because the air volume ratio is locked in advance, the air conditioning equipment cannot dynamically adjust the output air volume according to the vehicle's environment and the actual environment inside the cabin. This can easily lead to situations where the cooling needs of passengers' feet are not met in summer, or the warming needs of passengers' faces are not met in winter. As a result, the time it takes for passengers to reach a comfortable state is prolonged, significantly reducing the comfort of the vehicle. Summary of the Invention

[0010] In one embodiment, the air conditioning device further includes a defrost damper, and after the step of determining the preset first airflow distribution strategy as the target airflow distribution strategy of the air conditioning device, the method further includes: Read the window temperature difference features contained in the environmental feature dataset; If the window temperature difference feature is detected to reach a preset target feature threshold, a preset feature airflow mapping relationship is queried based on the window temperature difference feature to determine the target defrost airflow matching the window temperature difference feature. Based on the target defrosting air volume, determine the third target damper opening corresponding to the defrosting damper, and adjust the defrosting damper to the third target damper opening.

[0011] In one embodiment, the step of determining the target airflow ratio by combining the environmental feature dataset and the target airflow allocation strategy includes: If the target airflow allocation strategy is detected to be the second airflow allocation strategy, the current in-vehicle temperature, current outside-vehicle temperature, air conditioning set temperature and current light intensity contained in the environmental feature dataset are read. The vehicle interior temperature coefficient is determined based on the current vehicle interior temperature and the current vehicle exterior temperature, and the set temperature coefficient is determined based on the air conditioning set temperature and the current vehicle exterior temperature, and the light intensity coefficient is determined based on the current light intensity and the current vehicle exterior temperature. The target mode temperature is obtained by summing the in-vehicle temperature coefficient, the set temperature coefficient, and the light intensity coefficient. The target airflow ratio is determined based on the preset temperature ratio mapping relationship of the target mode temperature query.

[0012] In one embodiment, the step of determining the target airflow ratio by combining the environmental feature dataset and the target airflow allocation strategy includes: If the target airflow allocation strategy is detected to be the third airflow allocation strategy, the current in-vehicle temperature and the current outside-vehicle temperature contained in the environmental feature dataset are read. Based on the current interior temperature and the current exterior temperature, a preset temperature-airflow mapping relationship is queried to determine the initial airflow to the face. Read the air conditioning set temperature contained in the environmental feature dataset, and calculate a second temperature difference between the air conditioning set temperature and the current vehicle interior temperature; A first correction coefficient is determined based on the second temperature difference, and the initial blowing air volume is modified in combination with the first correction coefficient to obtain the target blowing air volume; The target airflow ratio is determined based on the target airflow volume.

The first correction coefficient is updated according to the coefficient adjustment value to obtain the second correction coefficient, and the target blowing air volume is updated in combination with the second correction coefficient.

[0014] In addition, to achieve the above objectives, this application also proposes an electronic device, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the damper opening control method described above.

[0015] In addition, to achieve the above objectives, this application also proposes a vehicle that includes electronic equipment and air conditioning equipment as described above, wherein the air conditioning equipment includes a face air vent, a foot air vent, and a defrost air vent.

[0016] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the damper opening control method described above.

[0017] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the damper opening control method described above.

[0018] The damper opening control method provided in this application embodiment is applied to a vehicle containing an air conditioning unit, which includes a face-blowing damper and a foot-blowing damper. The method involves acquiring an environmental feature dataset corresponding to the vehicle and determining the seasonal operating mode of the air conditioning unit; determining a target airflow allocation strategy for the air conditioning unit based on the seasonal operating mode; determining a target airflow ratio by combining the environmental feature dataset and the target airflow allocation strategy; determining the face-blowing airflow and foot-blowing airflow according to the target airflow ratio and the preset maximum airflow corresponding to the air conditioning unit; determining a first target damper opening for the face-blowing damper based on the face-blowing airflow; determining a second target damper opening for the foot-blowing damper based on the foot-blowing airflow; adjusting the face-blowing damper to the first target damper opening; and adjusting the foot-blowing damper to the second target damper opening.

[0019] In this embodiment, the electronic device first acquires an environmental feature dataset corresponding to the vehicle's environment during operation. Simultaneously, the electronic device detects the air conditioning equipment inside the vehicle to determine the seasonal operating mode of the air conditioning equipment. Then, based on the seasonal operating mode of the air conditioning equipment, the electronic device filters multiple preset airflow distribution strategies to determine a target airflow distribution strategy that matches the seasonal operating mode. Thus, combining the environmental feature dataset and the target airflow distribution strategy, the electronic device determines the target airflow ratio between the face airflow and the foot airflow. Next, based on the target airflow ratio and the preset maximum airflow, the electronic device determines the face airflow component and the foot airflow. Based on the face airflow, the electronic device determines the first target damper opening corresponding to the face damper, and based on the foot airflow, the electronic device determines the second target damper opening corresponding to the foot damper. Finally, the electronic device adjusts the face damper to adjust its current opening to the first target damper opening, and simultaneously adjusts the foot damper to adjust its current opening to the second target damper opening.

[0020] Thus, this application solves the technical problem in related technologies that air conditioning equipment cannot dynamically adjust the output air volume according to the actual environment. Specifically, this application adopts an air volume distribution strategy that matches the seasonal operating mode of the air conditioning equipment. Then, according to the air volume distribution strategy and environmental feature dataset, it determines the air volume ratio that matches the current operating condition, representing the ratio between the face air volume and the foot air volume. Based on the air volume ratio and the maximum air volume of the air conditioning equipment, it determines the target damper opening of the face damper and the foot damper, respectively. This allows the electronic equipment to dynamically adjust the face air volume and the foot air volume according to the environmental conditions of the vehicle and the actual environment inside the cabin. This avoids the situation where the face damper or foot damper is opened according to a fixed air volume ratio, which would make it difficult to meet the cooling needs of the occupants' feet in summer or the warming needs of the occupants' faces in winter. As a result, the occupants can quickly reach a comfortable state after entering the cabin, significantly improving the comfort of the vehicle. Attached Figure Description

[0030] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0031] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0032] In this embodiment, for ease of description, the following description uses an electronic device that can be connected to the air conditioning equipment configured in the vehicle, or a mobile terminal, data storage control terminal, PC, or other terminal connected to the electronic control unit (ECU) of the electronic device as the execution subject. It is understood that this electronic device can specifically be the ECU (Electronic Control Unit) within the vehicle.

[0033] Based on the aforementioned electronic equipment, the overall concept of the damper opening control method of this application is proposed.

[0034] With the continuous development of the automotive industry, the comfort of the car cabin has become one of the core indicators affecting the passenger experience. As the level of vehicle intelligence rapidly increases, passengers are placing higher demands on the airflow distribution of the vehicle's air conditioning system. In related technologies, vehicles default to only opening the face airflow in summer, and similarly, only opening the foot and face airflow in winter. In spring and autumn, the face and foot airflows are opened according to a fixed airflow ratio. However, because the airflow ratio is pre-locked, the air conditioning system cannot dynamically adjust the output airflow based on the vehicle's environment and the actual cabin conditions. This can easily lead to situations where the passenger's foot cooling needs are not met in summer, or the passenger's facial warming needs are not met in winter, thus prolonging the time it takes for passengers to reach a comfortable state and significantly reducing vehicle comfort.

[0035] To address the above issues, this application provides a method for controlling the opening of a damper. This method is applied to a vehicle containing an air conditioning unit, which includes a face-blowing damper and a foot-blowing damper. The method includes: acquiring an environmental feature dataset corresponding to the vehicle and determining the seasonal operating mode of the air conditioning unit; determining a target airflow allocation strategy for the air conditioning unit based on the seasonal operating mode, and determining a target airflow ratio by combining the environmental feature dataset and the target airflow allocation strategy; determining the face-blowing airflow and foot-blowing airflow according to the target airflow ratio and a preset maximum airflow corresponding to the air conditioning unit, and determining a first target damper opening for the face-blowing damper based on the face-blowing airflow, and a second target damper opening for the foot-blowing damper based on the foot-blowing airflow; adjusting the face-blowing damper to the first target damper opening, and adjusting the foot-blowing damper to the second target damper opening.

[0036] Thus, this application solves the technical problem in related technologies that air conditioning equipment cannot dynamically adjust the output air volume according to the actual environment. Specifically, this application adopts an air volume distribution strategy that matches the seasonal operating mode of the air conditioning equipment. Then, according to the air volume distribution strategy and environmental feature dataset, it determines the air volume ratio that matches the current operating condition, representing the ratio between the face air volume and the foot air volume. Based on the air volume ratio and the maximum air volume of the air conditioning equipment, it determines the target damper opening of the face damper and the foot damper, respectively. This allows the electronic equipment to dynamically adjust the face air volume and the foot air volume according to the environmental conditions of the vehicle and the actual environment inside the cabin. This avoids the situation where the face damper or foot damper is opened according to a fixed air volume ratio, which would make it difficult to meet the cooling needs of the occupants' feet in summer or the warming needs of the occupants' faces in winter. As a result, the occupants can quickly reach a comfortable state after entering the cabin, significantly improving the comfort of the vehicle.

[0037] Based on the overall concept of the damper opening control method of this application, the embodiments of this application provide a damper opening control method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating a first embodiment of the damper opening control method of this application. In this embodiment, the damper opening control method is applied to a vehicle containing an air conditioning unit, which includes a face damper and a foot damper. The damper opening control method includes steps S10 to S40: Step S10: Obtain the environmental feature dataset corresponding to the vehicle and determine the seasonal operating mode of the air conditioning equipment; Step S20: Determine the target air volume allocation strategy for the air conditioning equipment based on the seasonal operating mode, and determine the target air volume ratio by combining the environmental feature dataset and the target air volume allocation strategy; It should be noted that this environmental feature dataset is a set of quantitative parameters used to characterize the thermal load status of the passenger compartment and the external environment, including: current outside temperature, current inside temperature, current light intensity, and air conditioning set temperature. Furthermore, the seasonal operating modes specifically include: summer operating mode, spring / autumn operating mode, and winter operating mode. Additionally, the target airflow distribution strategy corresponds one-to-one with the seasonal operating modes, and is a control strategy used to calculate the airflow distribution ratio between the face airflow and the foot airflow. Moreover, this target airflow ratio is a single numerical value used to characterize the relative magnitude of the face airflow and the foot airflow, ranging from 0% to 100%. This means that when the air conditioning system has only face and foot airflow dampers, the sum of the face airflow ratio and the foot airflow ratio is 100%, and the sum of the face and foot airflow ratios does not exceed the preset maximum airflow of the air conditioning system.

[0038] In this embodiment, during operation, the electronic device first calls upon the various sensors configured in the vehicle to detect the environment in which the vehicle is located to obtain an environmental feature dataset. Simultaneously, the electronic device determines the seasonal operating mode of the air conditioning equipment in the vehicle based on the environmental feature data. Then, the electronic device reads its own configured storage module to obtain multiple preset airflow allocation strategies, and then filters the multiple preset airflow allocation strategies according to the seasonal operating mode to determine the target airflow allocation strategy that matches the current seasonal operating mode. The electronic device then queries the target airflow allocation strategy based on the environmental feature dataset to determine the target airflow ratio between the face airflow and the foot airflow.

[0039] For example, when the ECU is running, if it detects that the air conditioning unit in the vehicle is powered on, it first obtains an environmental feature dataset including the current interior temperature, the current exterior temperature, the air conditioning set temperature, and the current ambient light through multiple temperature sensors, light sensors, and the air conditioning controller configured in the vehicle. At this time, the ECU reads the seasonal operating mode flag of the air conditioning controller as summer operating mode / spring / autumn operating mode / winter operating mode. Then, the ECU reads the storage module to obtain the preset air volume allocation strategy corresponding to each of the summer operating mode, spring / autumn operating mode, and winter operating mode. Then, it filters each preset air volume allocation strategy according to the current seasonal operating mode of the air conditioning controller to determine the target air volume allocation strategy. The ECU substitutes the environmental feature dataset into the target air volume allocation strategy to determine the target air volume ratio between the face air volume and the foot air volume according to the target air volume allocation strategy and the environmental feature dataset.

[0040] It should be noted that, in this embodiment and another embodiment, after powering on, the air conditioning controller can first obtain the current outside temperature of the vehicle from the environmental feature dataset. At the same time, the air conditioning controller obtains a preset first seasonal temperature judgment threshold of 25℃ and a preset second seasonal temperature judgment threshold of 10℃. At this time, the air conditioning controller compares the current outside temperature with the first seasonal temperature judgment threshold and the second seasonal temperature judgment threshold respectively. Thus, when the current outside temperature is detected to be >25℃, the seasonal operating mode flag is set to "summer operating mode". Similarly, when the current outside temperature is detected to be <10℃, the seasonal operating mode flag is set to "winter operating mode". Similarly, when the current outside temperature is detected to be in the range of 10℃-25℃, the seasonal operating mode flag is set to "spring and autumn operating mode".

[0041] In this way, the electronic equipment can determine the seasonal operating mode of the air conditioning system based on the vehicle's environmental conditions and the actual cabin environment. Then, according to the air volume distribution strategy matched to the seasonal operating mode, it determines the air volume ratio between the face air volume and the foot air volume. This ensures that the air volume distribution ratio is accurately matched with the external environment and the cabin environment, avoiding situations where opening the face air vent or foot air vent according to a fixed air volume ratio would fail to meet the cooling needs of passengers' feet in summer or the warming needs of passengers' faces in winter. As a result, passengers can quickly reach a comfortable state after entering the cabin, significantly improving the comfort of the vehicle.

[0042] In one feasible implementation, the step of "determining the target air volume allocation strategy of the air conditioning equipment based on the seasonal operating mode" in step S20 above may specifically include steps S201 to S203: Step S201: When the seasonal operating mode is detected to be the preset summer operating mode, the preset first air volume allocation strategy is determined as the target air volume allocation strategy of the air conditioning equipment. or, Step S202: When the seasonal operating mode is detected to be the preset spring and autumn operating mode, the preset second air volume allocation strategy is determined as the target air volume allocation strategy of the air conditioning equipment. or, Step S203: If the seasonal operating mode is detected to be the preset winter operating mode, the preset third air volume distribution strategy is determined as the target air volume distribution strategy of the air conditioning equipment.

[0043] In this embodiment, after determining the seasonal operating mode of the air conditioning equipment, the electronic device first obtains a mode strategy mapping relationship containing multiple preset operating mode flag bits and preset allocation strategies corresponding to each of the multiple preset operating mode flag bits. At this time, if the electronic device detects that the seasonal operating mode is the summer operating mode, it queries the mode strategy mapping relationship based on the summer operating mode, so as to determine the first air volume allocation strategy that matches the summer operating mode as the target air volume allocation strategy among the preset first air volume allocation strategy, second air volume allocation strategy, and third air volume allocation strategy through the mode strategy mapping relationship. Alternatively, if the electronic device detects that the seasonal operating mode is spring and autumn, it queries the mode strategy mapping relationship based on the spring and autumn operating mode. Then, it determines the second air volume allocation strategy that matches the spring and autumn operating mode as the target air volume allocation strategy from the preset first air volume allocation strategy, second air volume allocation strategy, and third air volume allocation strategy through the mode strategy mapping relationship. Alternatively, if the electronic device detects that the seasonal operating mode is the winter operating mode, it queries the mode strategy mapping relationship based on the winter operating mode, and determines the third air volume allocation strategy that matches the winter operating mode as the target air volume allocation strategy from the preset first air volume allocation strategy, second air volume allocation strategy, and third air volume allocation strategy through the mode strategy mapping relationship.

[0044] In this way, electronic devices can dynamically determine the seasonal operating mode of the air conditioning equipment by combining the environmental conditions of the vehicle and the actual environment inside the cabin, and then match the air volume distribution strategy according to the seasonal operating mode.

[0045] In one feasible implementation, the step of "determining the target air volume ratio by combining the environmental feature dataset and the target air volume allocation strategy" in step S20 above may specifically include steps S204-S205: Step S204: If the target airflow allocation strategy is detected to be the first airflow allocation strategy, read the current in-vehicle temperature and the current outside vehicle temperature contained in the environmental feature dataset; Step S205: Calculate the first temperature difference between the current interior temperature and the current exterior temperature, and determine the target airflow ratio based on the first temperature difference.

[0046] In this embodiment, after determining the target airflow allocation strategy, if the electronic device detects that the target airflow allocation strategy is the first airflow allocation strategy mentioned above, it first reads the current in-vehicle temperature and the current outside temperature contained in the environmental feature dataset. Then, the electronic device compares the current in-vehicle temperature and the current outside temperature to determine the first temperature difference between the current in-vehicle temperature and the current outside temperature. At the same time, the electronic device determines multiple preset temperature thresholds contained in the first airflow allocation strategy, and compares the first temperature difference with the multiple preset temperature thresholds to determine the target airflow ratio that matches the first temperature difference based on the multiple comparison results.

[0047] For example, after determining the target airflow allocation strategy, if the ECU determines that the target airflow strategy is the aforementioned preset first airflow allocation strategy, it first reads the current in-vehicle temperature and the current outside temperature contained in the environmental feature dataset. Then, the electronic device calculates the first temperature difference between the current in-vehicle temperature and the current outside temperature. At the same time, the electronic device obtains the preset first temperature threshold of 20°C and the second temperature threshold of 5°C within the first airflow allocation strategy, and then determines the target airflow ratio that matches the current environmental conditions based on the first temperature difference, the first temperature threshold of 20°C and the second temperature threshold of 5°C.

[0048] In this way, the electronic equipment can determine the seasonal operating mode of the air conditioning system based on the vehicle's environmental conditions and the actual cabin environment. Then, according to the air volume distribution strategy matched to the seasonal operating mode, it determines the air volume ratio between the face air volume and the foot air volume. This ensures that the air volume distribution ratio is accurately matched with the external and cabin environments, avoiding the situation where opening the face or foot air vents according to a fixed air volume ratio would make it difficult to meet the cooling needs of the occupants' feet in summer. As a result, the occupants can quickly reach a comfortable state after entering the cabin, significantly improving the comfort of the vehicle.

[0049] In one feasible implementation, the step of "determining the target air volume ratio based on the first temperature difference" in step S205 above may specifically include steps S2051 to S2053: Step S2051: If the first temperature difference is detected to be greater than the preset first temperature threshold, the preset first air volume ratio is determined as the target air volume ratio. or, Step S2052: When the first temperature difference is detected to be less than the preset second temperature threshold, the preset second air volume ratio is determined as the target air volume ratio, wherein the second temperature threshold is less than the first temperature threshold and the second air volume ratio is greater than the first air volume ratio. or, Step S2053: When the first temperature difference is detected to be between the first temperature threshold and the second temperature threshold, a preset third air volume ratio is determined as the target air volume ratio, wherein the third air volume ratio is less than the second air volume ratio and greater than the first air volume ratio.

[0050] It should be noted that the first temperature threshold is a temperature parameter used to distinguish between a significantly overheated cabin and a moderately overheated cabin under summer operating conditions. Similarly, the second temperature threshold is lower than the first temperature threshold and is used to distinguish between a moderately overheated cabin and a cabin temperature close to the outside temperature. Furthermore, the preset first, second, and third airflow ratios are all face-to-foot airflow ratios that correspond one-to-one with the aforementioned threshold ranges. Their numerical relationship is fixed as first airflow ratio < third airflow ratio < second airflow ratio. This means that when the air conditioning unit only has face-to-foot airflow dampers, the sum of the first, second, and third airflow ratios, each complementing the foot-to-face airflow ratio, is 100%.

[0051] In this embodiment, after calculating the first temperature difference, the electronic device first obtains a preset first temperature threshold and a second temperature threshold that is less than the first temperature threshold. Then, the electronic device compares the first temperature difference with the first and second temperature thresholds respectively. If the first temperature difference is detected to be greater than the first temperature threshold, the electronic device determines the first airflow ratio, which has the smallest value among the preset first, second, and third airflow ratios, as the target airflow ratio. Similarly, if the first temperature difference is detected to be less than the second temperature threshold, the electronic device determines the second airflow ratio, which has the largest value among the preset first, second, and third airflow ratios, as the target airflow ratio. Likewise, if the first temperature difference is detected to be less than the first temperature threshold but greater than the second temperature threshold, the electronic device determines the third airflow ratio, which has the middle value among the preset first, second, and third airflow ratios, as the target airflow ratio.

[0052] For example, please refer to Figure 2 , Figure 2 This is a schematic diagram illustrating the process of determining the airflow ratio in the summer operating mode of the embodiment of the damper opening control method of this application. Figure 2As shown, after calculating the first temperature difference, the ECU first obtains the preset first temperature threshold of 20℃ and the second temperature threshold of 5℃. At the same time, the ECU determines the preset first airflow ratio as 85%, the second airflow ratio as 95%, and the third airflow ratio as 90%. At this time, the ECU compares the first temperature difference with the first temperature threshold of 20℃ and the second temperature threshold of 5℃ respectively. Then, if the ECU detects that the first temperature difference is >20℃, it determines that the air conditioning equipment is under high load, and that the passenger's feet have a high cooling demand. Therefore, among the preset first airflow ratio, second airflow ratio, and third airflow ratio, the smallest value of the first airflow ratio, 85%, is taken as the target airflow ratio, so that the final airflow of the air conditioning equipment is 15% of the maximum airflow for the feet and 85% of the maximum airflow for the face. Alternatively, if the ECU detects a first temperature difference of <5℃, it determines that the air conditioning system is under low load, and the interior and exterior temperatures are basically the same. The cooling demand for passengers' feet is low. Therefore, among the preset first, second, and third air volume ratios, the second air volume ratio of 95% is taken as the target air volume ratio, so that the final air volume of the air conditioning system is 5% of the maximum air volume for blowing on the feet and 95% of the maximum air volume for blowing on the face. Alternatively, if the ECU detects that the first temperature difference is within the range of 5℃-20℃, it determines that the air conditioning equipment is under medium load at this time, and then determines that the passenger's feet have a certain cooling demand. Therefore, among the preset first air volume ratio, second air volume ratio and third air volume ratio, the third air volume ratio, which is in the middle range, is taken as the target air volume ratio, so that the final air volume of the air conditioning equipment is 10% of the maximum air volume for blowing to the feet and 90% of the maximum air volume for blowing to the face.

[0053] In this way, the electronic equipment can determine the seasonal operating mode of the air conditioning system based on the vehicle's environmental conditions and the actual cabin environment. Then, according to the air volume distribution strategy matched to the seasonal operating mode, it determines the air volume ratio between the face air volume and the foot air volume. This ensures that the air volume distribution ratio is accurately matched with the external and cabin environments, avoiding the situation where opening the face or foot air vents according to a fixed air volume ratio would make it difficult to meet the cooling needs of the occupants' feet in summer. As a result, the occupants can quickly reach a comfortable state after entering the cabin, significantly improving the comfort of the vehicle.

[0054] In one feasible implementation, the step of "determining the target air volume ratio by combining the environmental feature dataset and the target air volume allocation strategy" in step S20 above may further include steps S206 to S209: Step S206: If the target airflow allocation strategy is detected to be the second airflow allocation strategy, read the current in-vehicle temperature, current outside-vehicle temperature, air conditioning set temperature and current light intensity contained in the environmental feature dataset; Step S207: Determine the in-vehicle temperature coefficient based on the current in-vehicle temperature and the current outside-vehicle temperature, and determine the set temperature coefficient based on the air conditioning set temperature and the current outside-vehicle temperature, and determine the light intensity coefficient based on the current light intensity and the current outside-vehicle temperature; Step S208: The in-vehicle temperature coefficient, the set temperature coefficient, and the light intensity coefficient are summed to obtain the target mode temperature; Step S209: Determine the target airflow ratio based on the preset temperature ratio mapping relationship of the target mode temperature query.

[0055] It should be noted that the in-vehicle temperature coefficient is a specific quantitative value used to characterize the degree of overheating of the vehicle cabin relative to the external environment. Similarly, the set temperature coefficient is a specific quantitative value used to characterize the degree of overheating of the external environment relative to the air conditioning set temperature. Likewise, the light intensity coefficient is a specific quantitative value used to quantify the degree of overheating of the vehicle cabin relative to the external environment caused by the current light intensity.

[0056] In this embodiment, after determining the target airflow allocation strategy, if the electronic device detects that the target airflow allocation strategy is the second airflow allocation strategy mentioned above, it first reads the current in-vehicle temperature, current outside vehicle temperature, current light intensity, and air conditioning set temperature contained in the environmental feature dataset. Then, the electronic device first reads the aforementioned storage module to obtain a first coefficient mapping table containing multiple preset in-vehicle temperatures, multiple preset outside vehicle temperatures, and preset in-vehicle temperature coefficients corresponding to the multiple preset in-vehicle temperatures and multiple preset outside vehicle temperatures, and then determines the in-vehicle temperature coefficient based on the current in-vehicle temperature and current outside vehicle temperature by querying the first coefficient mapping table. Simultaneously, the electronic device reads the storage module to obtain a second coefficient mapping table containing multiple preset set temperatures, multiple preset outside vehicle temperatures, and preset set temperature coefficients corresponding to the multiple preset set temperatures and multiple preset outside vehicle temperatures. The electronic device determines the set temperature coefficient by consulting a second coefficient mapping table based on the air conditioning set temperature and the current outside temperature. Simultaneously, the electronic device reads from the storage module to obtain a third coefficient mapping table containing multiple preset light intensities, multiple preset outside temperatures, and preset light intensity coefficients corresponding to each preset light intensity and preset outside temperature. It then consults the third coefficient mapping table based on the current light intensity and current outside temperature to determine the light intensity coefficient. Next, the electronic device sums the retrieved in-vehicle temperature coefficient, set temperature coefficient, and light intensity coefficient to obtain the target mode temperature matching the spring / autumn operating conditions. Finally, the electronic device reads a temperature ratio mapping relationship containing multiple preset mode temperatures and preset airflow ratios corresponding to each preset mode temperature, and then consults this temperature ratio mapping relationship based on the target mode temperature to determine the target airflow ratio.

[0057] For example, please refer to Figure 3 and Figure 4 ,in, Figure 3 This is a schematic diagram of a two-dimensional table illustrating the temperature coefficient mapping involved in the embodiment of the damper opening control method of this application. Figure 4 This is a schematic diagram of the temperature ratio mapping relationship involved in the first embodiment of the damper opening control method of this application. After the ECU determines the target airflow distribution strategy, if it detects that the target airflow distribution strategy is the second airflow distribution strategy mentioned above, it can first read the current in-vehicle temperature, current outside vehicle temperature, air conditioning set temperature, and current light intensity contained in the environmental feature dataset. At this time, the ECU first reads the storage module to obtain, as shown in the diagram. Figure 3As shown, a first temperature coefficient mapping two-dimensional table is composed of multiple preset in-vehicle temperatures, multiple preset out-of-vehicle temperatures, and preset in-vehicle temperature coefficients corresponding to the multiple preset in-vehicle temperatures and multiple preset out-of-vehicle temperatures respectively. Based on the current in-vehicle temperature and the current out-of-vehicle temperature, the first temperature coefficient mapping two-dimensional table is queried to determine the in-vehicle temperature coefficient corresponding to the current in-vehicle temperature and the current out-of-vehicle temperature in the first temperature coefficient mapping two-dimensional table. At the same time, the ECU obtains a second temperature coefficient mapping two-dimensional table composed of multiple preset set temperatures, multiple preset outside temperatures, and preset set temperature coefficients corresponding to the multiple preset set temperatures and multiple preset outside temperatures respectively. Based on the air conditioning set temperature and the current outside temperature, the ECU queries the second temperature coefficient mapping two-dimensional table to determine the set temperature coefficients corresponding to the air conditioning set temperature and the current outside temperature in the second temperature coefficient mapping two-dimensional table. At the same time, the ECU obtains a three-dimensional table of temperature coefficient mapping, which consists of multiple preset light intensity, multiple preset outside temperature, and preset light intensity coefficients corresponding to multiple preset light intensity and multiple preset outside temperature. Based on the current light intensity and current outside temperature, the ECU queries the three-dimensional table of temperature coefficient mapping to determine the light intensity coefficients corresponding to the current light intensity and current outside temperature in the three-dimensional table of temperature coefficient mapping. Next, the ECU sums the in-vehicle temperature coefficient, the set temperature coefficient, and the light intensity coefficient to obtain the target mode temperature that matches the spring and autumn operating conditions. Finally, the electronic devices obtain... Figure 4 As shown, there are multiple preset mode temperatures and multiple preset airflow ratios that match the preset mode temperatures. The temperature ratio mapping relationship is then queried based on the target mode temperature to determine the target airflow ratio that matches the target mode temperature.

[0058] In this way, electronic devices can determine the seasonal operating mode of the air conditioning equipment based on the vehicle's environmental conditions and the actual cabin environment. Then, based on the air volume distribution strategy matched to the seasonal operating mode, the air volume ratio between the face air volume and the foot air volume is determined, so that the air volume distribution ratio is accurately matched with the external environment and the cabin environment, allowing the occupants to quickly reach a comfortable state after entering the cabin, significantly improving the comfort of the vehicle.

[0059] In one feasible implementation, the step of "determining the target air volume ratio by combining the environmental feature dataset and the target air volume allocation strategy" in step S20 above may further include steps S210 to S214: Step S210: If the target airflow allocation strategy is detected to be the third airflow allocation strategy, read the current in-vehicle temperature and the current outside-vehicle temperature contained in the environmental feature dataset; Step S211: Based on the current in-vehicle temperature and the current outside vehicle temperature, query the preset temperature-airflow mapping relationship to determine the initial airflow to the face; Step S212: Read the air conditioning set temperature contained in the environmental feature dataset, and calculate the second temperature difference between the air conditioning set temperature and the current vehicle interior temperature; Step S213: Determine a first correction coefficient based on the second temperature difference, and modify the initial blowing air volume in combination with the first correction coefficient to obtain the target blowing air volume; Step S214: Determine the target air volume ratio based on the target air volume.

[0060] In this embodiment, after determining the target airflow allocation strategy, if the electronic device detects that the target airflow allocation strategy is the aforementioned third airflow allocation strategy, it first reads the current in-vehicle temperature and the current outside temperature from the environmental feature dataset. Then, the electronic device first reads the aforementioned storage module to obtain a temperature-airflow mapping relationship containing multiple preset in-vehicle temperatures, multiple preset outside temperatures, and multiple preset surface airflow volumes matching those preset in-vehicle temperatures and multiple preset outside temperatures. At this point, the electronic device queries this temperature-airflow mapping relationship based on the current in-vehicle temperature and the current outside temperature to determine the relationship between the current in-vehicle temperature and the current outside temperature. The electronic device matches the initial face airflow. Simultaneously, it reads the environmental feature dataset to obtain the air conditioning set temperature and calculates the second temperature difference between the air conditioning set temperature and the current vehicle interior temperature. Then, the electronic device obtains a preset feedforward mapping relationship and queries the feedforward mapping relationship based on the second temperature difference to obtain a first correction coefficient. The electronic device corrects the initial face airflow ratio according to the first correction coefficient to obtain the target face airflow. Finally, the electronic device determines the target foot airflow based on the target face airflow and the preset maximum airflow corresponding to the air conditioning device, and determines the target airflow ratio by combining the target face airflow and the target foot airflow.

[0061] For example, after determining the target airflow allocation strategy, if the ECU detects that the target airflow allocation strategy is the third airflow allocation strategy mentioned above, it first reads the current in-vehicle temperature and the current outside temperature contained in the environmental feature dataset. Then, the ECU reads the storage module to obtain a temperature-airflow mapping relationship containing multiple preset in-vehicle temperatures, multiple preset outside temperatures, and historical airflow matching multiple preset in-vehicle temperatures and multiple preset outside temperatures. At this time, the ECU queries the temperature-airflow mapping relationship based on the current in-vehicle temperature and the current outside temperature to determine the initial airflow corresponding to the current in-vehicle temperature and the current outside temperature. After that, the ECU reads the empty airflow in the environmental feature dataset. The ECU adjusts the set temperature to calculate the second temperature difference between the air conditioning set temperature and the current vehicle interior temperature. At this time, the ECU obtains a temperature difference coefficient mapping relationship containing multiple second temperature differences and multiple preset PI coefficients that match each preset second temperature difference. The EC queries the temperature difference coefficient mapping relationship based on the second temperature difference to determine the first proportional correction PI coefficient that matches the second temperature difference. The ECU then corrects the initial face airflow based on the first proportional correction PI coefficient to obtain the target face airflow. Finally, the ECU calculates the target foot airflow based on the target face airflow and the preset maximum airflow, and determines the target airflow ratio by combining the target face airflow and the target foot airflow.

[0062] In this way, the electronic equipment can determine the seasonal operating mode of the air conditioning system based on the environmental conditions of the vehicle and the actual environment inside the cabin. Then, according to the air volume distribution strategy matched by the seasonal operating mode, the air volume ratio between the face air volume and the foot air volume is determined. This ensures that the air volume distribution ratio is accurately matched with the external environment and the cabin environment, avoiding the situation where the face air vents or foot air vents are opened according to a fixed air volume ratio, which would make it difficult to meet the temperature needs of the occupants' faces in winter. As a result, the occupants can quickly reach a comfortable state after entering the cabin, significantly improving the comfort of the vehicle.

[0063] Step S30: Determine the face air volume and foot air volume according to the target air volume ratio and the preset maximum air volume corresponding to the air conditioning equipment, and determine the first target damper opening corresponding to the face damper based on the face air volume, and determine the second target damper opening corresponding to the foot damper based on the foot air volume. Step S40: Adjust the face blowing damper to the first target damper opening and adjust the foot blowing damper to the second target damper opening; In this embodiment, after determining the target airflow ratio, the electronic device first obtains the preset maximum airflow, and then determines the first target airflow opening corresponding to the face airflow damper based on the target airflow ratio and the maximum airflow. At the same time, the electronic device determines the second target airflow opening corresponding to the foot airflow damper based on the target airflow ratio and the maximum airflow. Finally, the electronic device sends the first target airflow opening and the second target airflow opening to the air conditioning controller, so that the air conditioning controller can adjust the current opening of the face airflow damper to the first target airflow opening and the current opening of the foot airflow damper to the second target airflow opening.

[0064] For example, after determining the target airflow ratio, the ECU inputs the target airflow ratio to the air conditioning controller. At this time, the air conditioning controller first determines the preset maximum airflow, and then determines the face airflow and foot airflow based on the target airflow ratio and the maximum airflow. Based on the face airflow, it determines the first target damper opening corresponding to the face damper. At the same time, it determines the second target damper opening corresponding to the foot damper based on the foot airflow. Finally, the air conditioning controller generates a first PWM signal for controlling the face damper based on the first target damper opening, and a second PWM signal for controlling the foot damper based on the second target damper opening. The air conditioning controller then drives the motor to rotate according to the first PWM signal, thereby pushing the face damper to the first target damper opening. At the same time, it drives the motor to rotate according to the second PWM signal, thereby pushing the foot damper to the second target damper opening.

[0065] In this embodiment, during operation, the electronic device first calls upon the various sensors configured in the vehicle to detect the vehicle's environment and obtain an environmental feature dataset. Simultaneously, the electronic device determines the seasonal operating mode of the vehicle's air conditioning system based on this environmental feature data. Then, the electronic device reads its own storage module to obtain multiple preset airflow allocation strategies. It then filters these strategies according to the seasonal operating mode to determine the target airflow allocation strategy that matches the current seasonal operating mode. The electronic device then queries this target airflow allocation strategy based on the environmental feature dataset to determine the target airflow ratio between the face airflow and the foot airflow. Next, the electronic device obtains the preset maximum airflow and determines the first target airflow opening corresponding to the face airflow damper based on the target airflow ratio and the maximum airflow. Simultaneously, the electronic device determines the second target airflow opening corresponding to the foot airflow damper based on the target airflow ratio and the maximum airflow. Finally, the electronic device sends the first and second target airflow openings to the air conditioning controller, so that the air conditioning controller can adjust the current opening of the face airflow damper to the first target airflow opening and the current opening of the foot airflow damper to the second target airflow opening.

[0066] Thus, this application solves the technical problem in related technologies that air conditioning equipment cannot dynamically adjust the output air volume according to the actual environment. Specifically, this application adopts an air volume distribution strategy that matches the seasonal operating mode of the air conditioning equipment. Then, according to the air volume distribution strategy and environmental feature dataset, it determines the air volume ratio that matches the current operating condition, representing the ratio between the face air volume and the foot air volume. Based on the air volume ratio and the maximum air volume of the air conditioning equipment, it determines the target damper opening of the face damper and the foot damper, respectively. This allows the electronic equipment to dynamically adjust the face air volume and the foot air volume according to the environmental conditions of the vehicle and the actual environment inside the cabin. This avoids the situation where the face damper or foot damper is opened according to a fixed air volume ratio, which would make it difficult to meet the cooling needs of the occupants' feet in summer or the warming needs of the occupants' faces in winter. As a result, the occupants can quickly reach a comfortable state after entering the cabin, significantly improving the comfort of the vehicle.

[0067] Based on the first embodiment of this application, a second embodiment of this application is proposed herein. In this second embodiment, content that is the same as or similar to the above embodiments can be referred to the above description and will not be repeated hereafter. Furthermore, after step S201 above, the air conditioning equipment further includes a defrost damper, and the damper opening control method of this application may further include steps A10~A30: Step A10: Read the window temperature difference features contained in the environmental feature dataset; Step A20: When the window temperature difference feature is detected to reach the preset target feature threshold, the preset feature airflow mapping relationship is queried based on the window temperature difference feature to determine the target defrost airflow matching the window temperature difference feature. Step A30: Determine the third target damper opening degree corresponding to the defrost damper based on the target defrost air volume, and adjust the defrost damper to the third target damper opening degree.

[0068] It should be noted that the window temperature difference feature is a characteristic parameter used to quantify the temperature difference between the inside and outside of the panoramic sunroof of a vehicle. This can be understood as including a temperature difference parameter that directly represents the temperature difference, and a light intensity parameter that indirectly represents the temperature difference. The temperature difference can be obtained by directly detecting the interior and exterior of the vehicle. Similarly, the light intensity parameter can be obtained by directly detecting the exterior of the vehicle. This light intensity parameter affects the heat absorption efficiency of the outer side of the panoramic sunroof, thereby indirectly changing the temperature difference between the inside and outside of the panoramic sunroof. Furthermore, the target feature threshold is a critical value used to determine whether defrosting operation needs to be initiated. This target feature threshold can be either a temperature difference threshold matched with the temperature difference parameter, or a light intensity threshold matched with the light intensity parameter.

[0069] In this embodiment, after determining the target airflow allocation strategy, if the electronic device detects that the target airflow allocation strategy is the first airflow allocation strategy mentioned above, it can further read the window temperature difference features contained in the environmental feature dataset and read the light intensity parameters contained in the window temperature difference features. Then, the electronic device obtains a preset light intensity threshold and compares the light intensity parameters with the light intensity threshold. Then, when it is detected that the light intensity parameters reach the light intensity threshold, it obtains a preset light intensity-airflow mapping relationship and queries the light intensity-airflow mapping relationship based on the light intensity parameters to determine the target defrost airflow matching the light intensity parameters. Finally, the electronic device inputs the target defrost airflow to the air conditioning controller. The air conditioning controller then calculates the third target airflow opening based on the target defrost control volume and the preset maximum defrost damper opening and adjusts the real-time opening of the defrost damper to the third target airflow opening.

[0070] For example, such as Figure 2 As shown, after determining the target airflow distribution strategy, if the ECU detects that the target airflow distribution strategy is the first airflow distribution strategy mentioned above, in addition to determining the target airflow ratio based on the first airflow distribution strategy, it can also first read the window temperature difference features contained in the environmental feature dataset, and read the light intensity parameter contained in the window temperature difference features. Then, the ECU obtains a preset light intensity threshold and compares the light intensity parameter with the light intensity threshold. At this time, if the ECU detects that the light intensity parameter is greater than the light intensity threshold, it determines that there may be a large temperature difference between the vehicle cabin interior and the external environment. A large temperature difference may lead to a certain risk of frost formation on the panoramic sunroof. At this time, the ECU reads the storage module... The ECU obtains a light-airflow mapping relationship containing multiple preset light intensities, multiple preset outside temperatures, and preset defrost airflow corresponding to each preset light intensity and preset outside temperature. The ECU then queries this light-airflow mapping relationship based on the window temperature difference characteristics and the current outside temperature to determine the target defrost airflow that matches the window temperature difference characteristics and the current outside temperature. Finally, the ECU inputs the target defrost airflow to the air conditioning controller, which calculates the third target damper opening based on the target defrost airflow and the preset maximum damper opening. The air conditioning controller then generates a third PWM signal based on the third target damper opening to adjust the current opening of the defrost damper to the third target damper opening according to the third PWM signal.

[0071] In this way, when the ambient light intensity is high, the electronic equipment can determine that the panoramic sunroof of the vehicle is prone to frost due to the large temperature difference between the cabin temperature and the external ambient temperature. Then, based on the window temperature difference characteristics and the current outside temperature, the target defrost air volume is determined, and the opening of the defrost damper is adjusted according to the target defrost air volume to reduce the risk of frost on the panoramic sunroof and further improve the comfort of the vehicle.

[0072] Based on the first and / or second embodiments of this application, a third embodiment of this application is proposed herein. Contents identical or similar to those in the second embodiment of this application can be referred to the above description and will not be repeated hereafter. Furthermore, after step S214 above, the method for controlling the damper opening of this application may further include steps B10 to B30: Step B10: Detect the trend of temperature difference change corresponding to the second temperature difference value; Step B20: If the temperature difference is detected to be decreasing, determine the coefficient adjustment value based on the change in temperature difference; Step B30: Update the first correction coefficient according to the coefficient adjustment value to obtain the second correction coefficient, and update the target blowing air volume in combination with the second correction coefficient.

[0073] In this embodiment, after determining the target air volume ratio based on the third air volume distribution strategy, the electronic device can further detect the change value of the second temperature difference to obtain the temperature difference change trend. Then, when the electronic device detects that the temperature difference change trend is a decrease in the difference change, it obtains a preset change value ratio mapping relationship. The electronic device then queries the change value ratio mapping relationship based on the temperature difference change value to obtain a coefficient adjustment value. Finally, the electronic device updates the first correction coefficient according to the coefficient adjustment value to obtain a second correction coefficient, and then updates the target face blowing air volume according to the second correction coefficient. Based on the updated target face blowing air volume, a new target air volume ratio is further determined, and the opening of the face blowing damper and foot blowing damper is adjusted according to the new target air volume ratio.

[0074] For example, after determining the target airflow ratio based on the third airflow distribution strategy described above, the ECU can further detect the changes in the second temperature difference to obtain multiple temperature difference change values. Then, the ECU determines the trend of the second temperature difference based on the multiple temperature difference change values. When it detects that the trend of the second temperature difference is a decrease in the difference, it determines that the occupant's foot heating requirement has decreased. At this time, the ECU obtains a preset mapping relationship of multiple preset temperature difference change values ​​and preset adjustment values ​​that match each of the multiple preset temperature difference change values. Based on the current temperature difference change value, it queries the mapping relationship of the change value to determine the coefficient adjustment value that matches the current temperature difference change value. Based on the coefficient adjustment value, it updates the first proportional correction PI coefficient to reduce the first proportional correction PI coefficient to the second proportional correction PI coefficient. At the same time, the ECU determines the target airflow of the target airflow ratio and updates the target airflow according to the second proportional correction PI coefficient so that the updated target airflow is lower than the target airflow. Then, it updates the first target damper opening and the second damper opening according to the updated target airflow.

[0075] In this way, the electronic devices can adaptively adjust the airflow to the face and feet in winter operating mode, thereby gradually reducing the airflow to the face and increasing the airflow to the feet as the interior temperature rises, further improving the comfort of the vehicle.

[0076] This application also provides a control device for the opening degree of a damper; please refer to [reference needed].

[0079] In one feasible implementation, the ratio determination module 20 is further configured to: If the first temperature difference is detected to be greater than the preset first temperature threshold, the preset first air volume ratio is determined as the target air volume ratio. or, If the first temperature difference is detected to be less than the preset second temperature threshold, the preset second air volume ratio is determined as the target air volume ratio, wherein the second temperature threshold is less than the first temperature threshold and the second air volume ratio is greater than the first air volume ratio. or, If the first temperature difference is detected to be between the first temperature threshold and the second temperature threshold, a preset third air volume ratio is determined as the target air volume ratio, wherein the third air volume ratio is less than the second air volume ratio and greater than the first air volume ratio.

[0080] In one feasible implementation, the air conditioning equipment further includes a defrost damper, and the damper adjustment module 40 is further used for: Read the window temperature difference features contained in the environmental feature dataset; If the window temperature difference feature is detected to reach a preset target feature threshold, a preset feature airflow mapping relationship is queried based on the window temperature difference feature to determine the target defrost airflow matching the window temperature difference feature. Based on the target defrosting air volume, determine the third target damper opening corresponding to the defrosting damper, and adjust the defrosting damper to the third target damper opening.

[0081] In one feasible implementation, the ratio determination module 20 is further configured to: If the target airflow allocation strategy is detected to be the second airflow allocation strategy, the current in-vehicle temperature, current outside-vehicle temperature, air conditioning set temperature, and window temperature difference features contained in the environmental feature dataset are read.

The target mode temperature is obtained by summing the in-vehicle temperature coefficient, the set temperature coefficient, and the light intensity coefficient. The target airflow ratio is determined based on the preset temperature ratio mapping relationship of the target mode temperature query.

[0082] In one feasible implementation, the ratio determination module 20 is further configured to: If the target airflow allocation strategy is detected to be the third airflow allocation strategy, the current in-vehicle temperature and the current outside-vehicle temperature contained in the environmental feature dataset are read.
