Summary of the Invention

[0003] This application provides a method, apparatus, device, and storage medium for controlling an in-vehicle air conditioner. The technical solution is as follows:

[0004] On one hand, embodiments of this application provide a method for controlling an in-vehicle air conditioner, the method comprising:

[0005] The actual temperature inside the vehicle and the body surface temperature of the occupants are obtained according to the reference frequency.

[0006] The ambient temperature deviation is calculated based on the actual temperature inside the vehicle, resulting in multiple ambient temperature deviations. The body surface temperature deviation of the occupants is calculated based on their body surface temperature, resulting in multiple body surface temperature deviations of the occupants.

[0007] A first membership function graph corresponding to the multiple environmental temperature deviations is determined, and a second membership function graph corresponding to the multiple personnel body surface temperature deviations is determined. The first membership function graph is a function graph of the membership degree of the multiple environmental temperature deviations belonging to different deviation ranges, and the second membership function graph is a function graph of the membership degree of the multiple personnel body surface temperature deviations belonging to different deviation ranges.

[0008] A behavioral variable is defined, which indicates the change in the temperature regulation of the vehicle's air conditioning system. A third membership function graph corresponding to the behavioral variable is determined, which is a function graph of the membership degree of the temperature regulation deviation of the vehicle's air conditioning system belonging to different deviation ranges.

[0009] Based on the consistency of the changing trends of the ambient temperature deviation, the human body surface temperature deviation, and the vehicle air conditioning temperature adjustment deviation in the first membership function graph, the second membership function graph, and the third membership function graph, the first correspondence between the vehicle air conditioning control mode and the vehicle air conditioning temperature adjustment deviation in the third membership function graph is converted into a second correspondence between the vehicle air conditioning control mode and the ambient temperature deviation and the human body surface temperature deviation in the first membership function graph and the second membership function graph.

[0010] Based on the second correspondence, a control strategy for controlling the vehicle air conditioning by controlling the ambient temperature deviation and the personnel body surface temperature deviation is obtained.

[0011] Based on the control strategy, a target control mode is determined corresponding to the currently acquired actual temperature inside the vehicle and the body surface temperature of the occupants inside the vehicle, and the vehicle air conditioning is controlled according to the target control mode.

[0012] On the other hand, a control device for an in-vehicle air conditioning system is provided, the device comprising:

[0013] The acquisition module is used to acquire the actual temperature inside the vehicle and the body surface temperature of the occupants according to a reference frequency.

[0014] The calculation module is used to calculate the ambient temperature deviation based on the actual temperature inside the vehicle, and to obtain multiple ambient temperature deviations; and to calculate the body surface temperature deviation based on the body surface temperature of the occupants inside the vehicle, and to obtain multiple body surface temperature deviations of the occupants.

[0015] The first determining module is used to determine the first membership function graph corresponding to the plurality of ambient temperature deviations and the second membership function graph corresponding to the plurality of personnel body surface temperature deviations. The first membership function graph is a function graph of the membership degree of the plurality of ambient temperature deviations belonging to different deviation ranges, and the second membership function graph is a function graph of the membership degree of the plurality of personnel body surface temperature deviations belonging to different deviation ranges.

[0016] The second determining module is used to determine a behavioral variable, which indicates the change in the temperature regulation of the vehicle air conditioner, and to determine the third membership function graph corresponding to the behavioral variable. The third membership function graph is a function graph of the membership degree of the temperature regulation deviation of the vehicle air conditioner belonging to different deviation ranges.

[0017] The conversion module is used to convert the first correspondence between the control mode of the in-vehicle air conditioner and the adjustment temperature deviation of the in-vehicle air conditioner in the third membership function diagram into a second correspondence between the different control modes of the in-vehicle air conditioner and the ambient temperature deviation and the human body surface temperature deviation in the first and second membership function diagrams, based on the consistency of the changing trends of the ambient temperature deviation, the human body surface temperature deviation and the adjustment temperature deviation of the in-vehicle air conditioner in the first, second and third membership function diagrams.

[0018] The obtaining module is used to obtain a control strategy for controlling the in-vehicle air conditioning based on the second correspondence relationship, which controls the ambient temperature deviation and the personnel body surface temperature deviation.

[0019] The control module is used to determine the target control mode corresponding to the currently acquired actual temperature inside the vehicle and the body surface temperature of the occupants inside the vehicle based on the control strategy, and to control the vehicle air conditioning according to the target control mode.

[0020] On the other hand, a computer device is provided, the computer device including a processor and a memory, the memory storing at least one computer program, the at least one computer program being loaded and executed by the processor, so that the computer device implements any of the above-described vehicle air conditioning control methods.

[0022] On the other hand, a computer program product or computer program is also provided, which includes computer instructions stored in a computer-readable storage medium. A processor of a computer device reads the computer instructions from the computer-readable storage medium and executes the computer instructions, causing the computer device to perform any of the above-described vehicle air conditioning control methods.

[0023] The technical solution provided in this application has at least the following beneficial effects:

[0024] This application embodiment obtains a first membership function graph representing the membership degree of different deviation ranges of the ambient temperature deviation by performing fuzzy mapping on the actual temperature inside the vehicle. It also obtains a second membership function graph representing the membership degree of different deviation ranges of the body surface temperature deviation of the occupants by performing fuzzy mapping on the body surface temperature deviation of the occupants. Furthermore, it determines a third membership function graph representing the membership degree of different deviation ranges of the regulated temperature deviation of the vehicle's air conditioning system. Based on the consistency of the changing trends of the ambient temperature deviation, the occupant's body surface temperature deviation, and the regulated temperature deviation of the vehicle's air conditioning system in the first, second, and third membership function graphs, a control strategy for controlling the vehicle's air conditioning system using the ambient temperature deviation and the occupant's body surface temperature deviation is obtained. Then, based on this control strategy, the vehicle's air conditioning system is controlled according to the target control mode corresponding to the currently obtained actual temperature inside the vehicle and the occupants' body surface temperatures, achieving automatic control of the air conditioning system, making the control more accurate and efficient.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0037] This application provides a method for controlling an in-vehicle air conditioner. Please refer to [link / reference]. Figure 1 The diagram illustrates the implementation environment of the method provided in this application embodiment. This implementation environment may include: a vehicle 11 and a vehicle control system 12.

[0038] The vehicle 11 is equipped with an air conditioner. The vehicle control system 12 determines a behavioral variable based on the deviation of the ambient temperature inside the vehicle 11 and the deviation of the body temperature of the occupants. This behavioral variable indicates the change in the regulated temperature of the air conditioner. Based on the consistency of the changing trends of the ambient temperature deviation inside the vehicle 11, the body temperature deviation of the occupants, and the regulated temperature deviation of the air conditioner, a control strategy for controlling the air conditioner by means of these two deviations is obtained. Based on the control strategy, a target control mode for the air conditioner is determined, and the air conditioner is controlled based on this target control mode. The vehicle control system 12 can store the target control mode.

[0039] Optionally, the vehicle control system 12 can be a single server, a server cluster consisting of multiple servers, or a cloud computing service center. The vehicle 11 and the vehicle control system 12 establish a communication connection via a wired or wireless network.

[0040] Those skilled in the art should understand that vehicle 11 and vehicle control system 12 are merely examples, and other existing or future temperature-regulating terminals or servers that are applicable to this application should also be included within the scope of protection of this application, and are hereby incorporated by reference.

[0041] Based on the above Figure 1 As shown in the implementation environment, this application embodiment provides a method for controlling an in-vehicle air conditioner. Figure 2 As shown, the control method for the in-vehicle air conditioning can be executed by the vehicle control system, and the method includes steps 201-207.

[0042] In step 201, the actual temperature inside the vehicle and the body surface temperature of the occupants inside the vehicle are obtained according to the reference frequency.

[0043] This application does not limit the method of obtaining the actual temperature inside the vehicle and the body surface temperature of the people inside the vehicle. Taking obtaining the actual temperature inside the vehicle and the body surface temperature of the people inside the vehicle through an ambient temperature sensor and an infrared imaging thermometer as an example, an ambient temperature sensor and an infrared imaging thermometer can be installed inside the vehicle. The ambient temperature sensor can obtain the actual temperature inside the vehicle, and the infrared imaging thermometer can obtain the body surface temperature of the people inside the vehicle.

[0044] In one possible implementation, the actual temperature inside the vehicle and the body surface temperature of the occupants are acquired at a reference frequency, including: acquiring the body surface temperature of the occupants at a reference frequency using an infrared imaging thermometer, and acquiring the actual temperature inside the vehicle at a reference frequency using an ambient temperature sensor.

[0045] This application does not limit the reference frequency; it can be set and adjusted based on experience or scenario. For example, the reference frequency can be twice per minute.

[0046] In step 202, the ambient temperature deviation is calculated based on the actual temperature inside the vehicle, resulting in multiple ambient temperature deviations. The body surface temperature deviation of the occupants is calculated based on their body surface temperature, resulting in multiple body surface temperature deviations of the occupants.

[0047] In one possible implementation, the ambient temperature deviation is calculated based on the actual temperature inside the vehicle, resulting in multiple ambient temperature deviations. Similarly, the body surface temperature deviation of the occupants is calculated based on their body surface temperatures, resulting in multiple body surface temperature deviations. This includes: determining the air conditioning operating mode based on the actual temperature inside the vehicle, where the operating mode may be either cooling or heating; determining a reference temperature inside the vehicle and a perceived reference temperature based on the air conditioning operating mode; subtracting the actual temperature inside the vehicle from the reference temperature to obtain multiple ambient temperature deviations; and subtracting the body surface temperatures of the occupants from the perceived reference temperatures to obtain multiple body surface temperature deviations.

[0048] This application does not limit the method of determining the air conditioning usage mode based on the actual temperature inside the vehicle. For example, each time the vehicle control system obtains the actual temperature inside the vehicle and the body surface temperature of the occupants, it compares the actual temperature inside the vehicle with a preset first temperature threshold and a second temperature threshold to determine the air conditioning usage mode. The air conditioning usage mode includes a cooling mode or a heating mode. When the actual temperature inside the vehicle is higher than the first temperature threshold, the air conditioning usage mode is cooling mode, and when the actual temperature inside the vehicle is lower than the second temperature threshold, the air conditioning usage mode is heating mode.

[0049] This application does not limit the first temperature threshold and the second temperature threshold; they can be set based on experience or adjusted based on the scenario.

[0050] After determining whether the air conditioning is in cooling or heating mode, the in-vehicle reference temperature and the perceived reference temperature are set based on the air conditioning's operating mode. This application does not limit the standards for setting the in-vehicle reference temperature and the perceived reference temperature. For example, the in-vehicle reference temperature when the air conditioning is in cooling mode should be higher than the in-vehicle reference temperature when the air conditioning is in heating mode, and the perceived reference temperature when the air conditioning is in cooling mode should be higher than the perceived reference temperature when the air conditioning is in heating mode.

[0051] After setting the in-vehicle reference temperature and perceived reference temperature, the difference between the actual in-vehicle temperature and the reference temperature is calculated, and this difference is taken as the ambient temperature deviation. The actual in-vehicle temperature can be denoted as Tk, where k is the reference frequency. The in-vehicle reference temperature corresponding to the current air conditioning operating mode is denoted as Tr, and the ambient temperature deviation corresponding to the current air conditioning operating mode is denoted as ΔT, i.e., ΔT = Tk - Tr. The difference between the body surface temperature of the occupants and the perceived reference temperature is calculated, and the result is taken as the occupant body surface temperature deviation. The occupant body surface temperature is denoted as tk, where k is the reference frequency. The perceived reference temperature corresponding to the current air conditioning operating mode is denoted as tr, and the occupant body surface temperature deviation corresponding to the current air conditioning operating mode is denoted as Δt, i.e., Δt = tk - tr.

[0052] In step 203, a first membership function graph corresponding to multiple environmental temperature deviations is determined, and a second membership function graph corresponding to multiple personnel body surface temperature deviations is determined. The first membership function graph is a function graph of the membership degree of multiple environmental temperature deviations belonging to different deviation ranges, and the second membership function graph is a function graph of the membership degree of multiple personnel body surface temperature deviations belonging to different deviation ranges.

[0053] The first membership function graph is a function graph of the membership degrees of multiple environmental temperature deviations belonging to different deviation ranges. Determining the first membership function graph corresponding to multiple environmental temperature deviations includes: classifying multiple environmental temperature deviations into a first reference number of environmental temperature difference categories according to their magnitude; for any environmental temperature difference category among the first reference number of environmental temperature difference categories, describing the changing trend of the first relationship between the environmental temperature deviation and the corresponding membership degree in any environmental temperature difference category, and obtaining the first linguistic variable corresponding to any environmental temperature difference category; establishing a first trigonometric function based on the correspondence between multiple environmental temperature deviations and their corresponding membership degrees; obtaining the first membership function graph based on the first trigonometric function and the first linguistic variable, where the horizontal axis of the first membership function graph represents multiple environmental temperature deviations, and the vertical axis of the first membership function graph represents the membership degree corresponding to multiple environmental temperature deviations.

[0054] This application does not limit the number of first references; it can be set based on experience or adjusted based on the scenario. Taking a first reference number of 5 and ambient temperature deviations including -20℃, -15℃, -12℃, -10℃, -8℃, -6℃, -4℃, -2℃, 0℃, 2℃, 4℃, 6℃, 8℃, 10℃, 12℃, 15℃, and 20℃ as an example, the ambient temperature deviations are divided into 5 categories according to their magnitude. The first category includes -20℃, -15℃, -12℃, and -10℃; the second category includes -15℃, -12℃, -10℃, -8℃, -6℃, -4℃, and -2℃; the third category includes -4℃, -2℃, 0℃, 2℃, and 4℃; the fourth category includes 2℃, 4℃, 6℃, 8℃, 10℃, 12℃, and 15℃; and the fifth category includes 10℃, 12℃, 15℃, and 20℃.

[0055] For example, the trend of change in the first relationship between environmental temperature deviation and its corresponding membership degree in any environmental temperature difference category is described. For instance, the trend can be described using lower, low, ok, high, and higher as first linguistic variables to describe the trend of change in the first relationship between environmental temperature deviation ΔT and its corresponding membership degree. Here, the trend of change in the first relationship indicates the trend of change in the membership degree corresponding to the environmental temperature deviation as the environmental temperature deviation changes within any environmental temperature difference category.

[0056] The graph of the first membership function obtained from the first trigonometric function and the first linguistic variable can be seen as follows: Figure 3 As shown, the first membership function graph includes: a first triangle with two equally wide regions symmetrical about the origin as its base and a height of 1. The first triangle is an isosceles triangle. Symmetrically positioned on the left and right sides of the first triangle are four reference-numbered second triangles, each with a height of 1. The distance between each second triangle is the first reference width. Outside the midpoint of the base of the outermost second triangle is half a third triangle. The third triangle partially overlaps with the outermost second triangle, and the vertices of the third triangle extend a ray parallel to the horizontal axis, extending to infinity or infinitesimal on the left and right sides respectively. The fourth reference number is the first reference number minus three. The horizontal coordinate range of the base of each triangle function corresponds to the range of environmental temperature deviation for each environmental temperature difference category.

[0057] exist Figure 3 In the graph, multiple ambient temperature deviations are used as the horizontal axis of the first membership function graph, and the membership degrees corresponding to the multiple ambient temperature deviations are used as the vertical axis of the first membership function graph. Figure 3The horizontal axis of the base of the first triangle from left to right corresponds to the range of ambient temperature deviation in the first category, from -20℃ to -10℃. Within this range, the trigonometric function relationship between the ambient temperature deviation and its membership in the first category is linear. Therefore, within the horizontal axis range of -20℃ to -10℃, as the ambient temperature deviation increases, the membership in the first category decreases. For example, using `lower` to describe the first trigonometric function within the range of -20℃ to -10℃ yields the first membership function graph for that range.

[0058] Figure 3 The horizontal coordinate range of the base of the second triangle from left to right corresponds to the range of ambient temperature deviation in the second category, from -15℃ to -2℃. Within this range, the trigonometric function relationship between the ambient temperature deviation and its membership in the second category is linear and consists of two parts. For example... Figure 3 As shown, within the range of -15℃ to -8℃ on the horizontal axis, the membership degree of the corresponding second category increases with the increase of the ambient temperature deviation; within the range of -8℃ to -2℃ on the horizontal axis, the membership degree of the corresponding first category decreases with the increase of the ambient temperature deviation. Using `low` to describe the first trigonometric function within the range of -15℃ to -2℃, we obtain the first membership function graph within the range of -15℃ to -2℃ on the horizontal axis.

[0059] Figure 3 The horizontal coordinate range of the base of the third triangle from left to right corresponds to the range of ambient temperature deviation in the third category, from -4℃ to 4℃. Within this range, the trigonometric function relationship between the ambient temperature deviation and its membership in the third category is linear and consists of two parts. For example, within the horizontal coordinate range of -4℃ to 0℃, the membership in the third category increases with increasing ambient temperature deviation; conversely, within the horizontal coordinate range of 0℃ to 4℃, the membership in the first category decreases with increasing ambient temperature deviation. Using the ok algorithm to describe the first trigonometric function within the range of -4℃ to 4℃, we obtain the first membership function graph for this range.

[0060] Figure 3The horizontal axis of the base of the fourth triangle from left to right corresponds to the range of ambient temperature deviation in the fourth category, from 2℃ to 15℃. Within this range, the trigonometric function relationship between the ambient temperature deviation and its membership in the fourth category is linear and consists of two parts. For example, within the range of 2℃ to 8℃, the membership in the fourth category increases with increasing ambient temperature deviation; conversely, within the range of 8℃ to 15℃, the membership in the first category decreases with increasing ambient temperature deviation. Using `high` to describe the first trigonometric function within the range of 2℃ to 15℃ yields the first membership function graph for this range.

[0061] Figure 3 The horizontal coordinate range of the base of the fifth triangle from left to right corresponds to the environmental temperature deviation range of 10℃ to 20℃ in the fifth category. Within this range, the trigonometric function relationship between the environmental temperature deviation and its membership degree in the fifth category is linear. For example, within the horizontal coordinate range of 10℃ to 20℃, the membership degree of the corresponding fifth category increases with the increase of the environmental temperature deviation. Using `higher` to describe the first trigonometric function within the horizontal coordinate range of 10℃ to 20℃ yields the first membership function graph for this range.

[0062] The correspondence between ambient temperature deviation and the membership degree of ambient temperature deviation to each category is as follows: Figure 4 As shown, when the ambient temperature deviation is -20℃, the membership degree of the ambient temperature deviation belonging to the first category is 1, and the membership degree of the other categories is 0; when the ambient temperature deviation is -15℃, the membership degree of the ambient temperature deviation belonging to the first category is 0.5, and the membership degree of the other categories is 0; when the ambient temperature deviation is -12℃, the membership degree of the ambient temperature deviation belonging to the first category is 0.2, the membership degree of the second category is 0.42, and the membership degree of the other categories is 0.

[0063] When the ambient temperature deviation is -10℃, the membership degree of the ambient temperature deviation belonging to the second category is 0.72, and the membership degree belonging to the other categories is 0; when the ambient temperature deviation is -8℃, the membership degree of the ambient temperature deviation belonging to the second category is 1, and the membership degree belonging to the other categories is 0; when the ambient temperature deviation is -6℃, the membership degree of the ambient temperature deviation belonging to the second category is 0.67, and the membership degree belonging to the other categories is 0; when the ambient temperature deviation is -4℃, the membership degree of the ambient temperature deviation belonging to the second category is 0.33, and the membership degree belonging to the other categories is 0; when the ambient temperature deviation is -2℃, the membership degree of the ambient temperature deviation belonging to the third category is 0.5, and the membership degree belonging to the other categories is 0.

[0064] When the ambient temperature deviation is 0℃, the membership degree of the ambient temperature deviation belonging to the third category is 1, and the membership degree of the other categories is 0; when the ambient temperature deviation is 2℃, the membership degree of the ambient temperature deviation belonging to the third category is 0.5, and the membership degree of the other categories is 0; when the ambient temperature deviation is 4℃, the membership degree of the ambient temperature deviation belonging to the fourth category is 0.33, and the membership degree of the other categories is 0; when the ambient temperature deviation is 6℃, the membership degree of the ambient temperature deviation belonging to the fourth category is 0.67, and the membership degree of the other categories is 0; when the ambient temperature deviation is 8℃, the membership degree of the ambient temperature deviation belonging to the fourth category is 1, and the membership degree of the other categories is 0.

[0065] When the ambient temperature deviation is 10℃, the membership degree of the ambient temperature deviation belonging to category 4 is 0.67, and the membership degree belonging to other categories is 0; when the ambient temperature deviation is 12℃, the membership degree of the ambient temperature deviation belonging to category 4 is 0.33, the membership degree belonging to category 5 is 0.2, and the membership degree belonging to other categories is 0; when the ambient temperature deviation is 15℃, the membership degree of the ambient temperature deviation belonging to category 5 is 0.5, and the membership degree belonging to other categories is 0; when the ambient temperature deviation is 20℃, the membership degree of the ambient temperature deviation belonging to category 5 is 1, and the membership degree belonging to other categories is 0.

[0066] In one possible implementation, the second membership function graph is a function graph of the membership degrees of multiple personnel body surface temperature deviations belonging to different deviation ranges. Determining the second membership function graph corresponding to multiple personnel body surface temperature deviations includes: classifying the multiple personnel body surface temperature deviations into a second reference number of personnel body surface temperature difference categories according to their magnitude; for any personnel body surface temperature difference category in the second reference number of personnel body surface temperature difference categories, describing the changing trend of the second relationship between the personnel body surface temperature deviation and the corresponding membership degree in any personnel body surface temperature difference category, and obtaining a second linguistic variable corresponding to any personnel body surface temperature difference category; establishing a second trigonometric function based on the correspondence between multiple personnel body surface temperature deviations and their corresponding membership degrees; obtaining the second membership function graph based on the second trigonometric function and the second linguistic variable, where the horizontal axis of the second membership function graph represents the multiple personnel body surface temperature deviations, and the vertical axis of the second membership function graph represents the membership degrees corresponding to the multiple personnel body surface temperature deviations.

[0067] This application embodiment does not limit the number of second reference values; it can be set based on experience or adjusted based on the scenario. Taking a first reference value of 5 and a range of human body surface temperature deviations including -0.5, -0.4, -0.3, -0.2, -0.1, 0, 0.1, 0.2, 0.3, 0.4, and 0.5 as an example, the human body surface temperature deviations are divided into 5 categories according to their magnitude: the first category includes -0.5, -0.4, and -0.3; the second category includes -0.4, -0.3, -0.2, -0.1, and 0; the third category includes -0.2, -0.1, 0, 0.1, and 0.2; the fourth category includes 0, 0.1, 0.2, 0.3, and 0.4; and the fifth category includes 0.3, 0.4, and 0.5.

[0068] For example, the trend of the second relationship between the temperature deviation and the corresponding membership degree in any category of personnel body surface temperature difference is described, including using cold, cool, okay, warm, and hot as second language variables to describe the trend of the second relationship between the temperature deviation Δt and the corresponding membership degree. The trend of the second relationship indicates the trend of the membership degree corresponding to the temperature deviation as the temperature deviation changes in any category of personnel body surface temperature difference.

[0069] like Figure 5 As shown, the deviations in body surface temperature of multiple individuals are used as the x-axis of the second membership function graph, and the membership degrees corresponding to these deviations are used as the y-axis. In one possible approach, the second membership function graph is obtained based on the second trigonometric function and the second linguistic variable, as shown below. Figure 5 As shown, the second membership function graph includes a fourth triangle with a height of 1, formed by two equally wide regions symmetrical about the origin. This fourth triangle is isosceles. Symmetrical fifth reference triangles are located on either side of the fourth triangle. The height of each fifth triangle is 1, and the distance between each fifth triangle is the second reference width. A half-sixth triangle is located outside the midpoint of the base of the outermost fifth triangle. The sixth triangles partially overlap with the outermost fifth triangles, and their vertices extend a ray parallel to either infinitesimal or infinitesimal along the coordinate axes on either the left or right. The number of fifth reference triangles is the number of second reference triangles minus three. The range of the horizontal coordinates containing the base of each triangle corresponds to the range of environmental temperature deviation for each individual's body surface temperature category.

[0070] exist Figure 5In this diagram, multiple body surface temperature deviations are used as the x-axis of a second membership function graph, and the membership degrees corresponding to these deviations are used as the y-axis. The x-axis range of the base of the first triangle from left to right corresponds to the range of body surface temperature deviations in the sixth category, from -0.5℃ to -0.3℃. Within this range, the trigonometric function relationship between the body surface temperature deviation and its membership degree in the sixth category is linear. For example, within the x-axis range of -0.5℃ to -0.3℃, as the body surface temperature deviation increases, the membership degree of the corresponding first category decreases. The second trigonometric function within the range of -0.5℃ to -0.3℃ is described using the term "cold," resulting in a second membership function graph within this range.

[0071] The horizontal axis range of the base of the second triangle from left to right corresponds to the range of body surface temperature deviation in category seven, from -0.4℃ to 0℃. Within this range, the trigonometric function relationship between body surface temperature deviation and its membership in category two is linear and consists of two parts. For example, within the horizontal axis range of -0.4℃ to -0.2℃, the membership in category seven increases with increasing body surface temperature deviation; conversely, within the horizontal axis range of -0.2℃ to 0℃, the membership in category one decreases with increasing body surface temperature deviation. Using `cool` to describe the second trigonometric function within the range of -0.4℃ to 0℃ yields the second membership function graph for this range.

[0072] The horizontal axis range of the base of the third triangle from left to right corresponds to the range of body surface temperature deviation in category eight, from -0.2℃ to 0.2℃. Within this range, the trigonometric function relationship between body surface temperature deviation and its membership in category three is linear and consists of two parts. For example, within the horizontal axis range of -0.2℃ to 0℃, as body surface temperature deviation increases, the membership in category eight increases; conversely, within the horizontal axis range of 0℃ to 0.2℃, as body surface temperature deviation increases, the membership in category one decreases. Using ok to describe the second trigonometric function within the range of -0.2℃ to 0.2℃, we obtain the second membership function graph within this range.

[0073] The horizontal axis range of the base of the fourth triangle from left to right corresponds to the range of body surface temperature deviation in category nine, from 0℃ to 0.4℃. Within this range, the trigonometric function relationship between body surface temperature deviation and its membership in category four is linear and consists of two parts. For example, within the horizontal axis range of 0℃ to 0.2℃, the membership in category nine increases with increasing body surface temperature deviation; conversely, within the horizontal axis range of 0.2℃ to 0.4℃, the membership in category one decreases with increasing body surface temperature deviation. Using the term "warm" to describe the second trigonometric function within the range of 0℃ to 0.4℃, we obtain the second membership function graph for this range.

[0074] The horizontal axis range of the base of the fifth triangle from left to right corresponds to the range of 0.3℃ to 0.5℃ for the surface temperature deviation of personnel in the tenth category. Within this range, the trigonometric function relationship between the surface temperature deviation and its membership in the tenth category is linear. For example, within the horizontal axis range of 0.3℃ to 0.5℃, as the surface temperature deviation increases, the membership in the fifth category increases. Using HOT to describe the second trigonometric function within the horizontal axis range of 0.3℃ to 0.5℃ yields the second membership function graph for this range.

[0075] The correspondence between the deviation of personnel body surface temperature and the degree of membership of the deviation of personnel body surface temperature to each category is as follows: Figure 6 As shown, when the personnel's body surface temperature deviation is -0.5℃, the membership degree of the personnel's body surface temperature deviation belonging to category 6 is 1, and the membership degree belonging to other categories is 0; when the personnel's body surface temperature deviation is -0.4℃, the membership degree of the personnel's body surface temperature deviation belonging to category 6 is 0.5, and the membership degree belonging to other categories is 0; when the personnel's body surface temperature deviation is -0.3℃, the membership degree of the personnel's body surface temperature deviation belonging to category 7 is 0.5, and the membership degree belonging to other categories is 0; when the personnel's body surface temperature deviation is -0.2℃, the membership degree of the personnel's body surface temperature deviation belonging to category 7 is 1, and the membership degree belonging to other categories is 0; when the personnel's body surface temperature deviation is -0.1℃, the membership degree of the personnel's body surface temperature deviation belonging to category 7 is 0.5, the membership degree belonging to category 8 is 0.5, and the membership degree belonging to other categories is 0.

[0076] When the deviation of a person's body surface temperature is 0℃, the membership degree of the deviation belonging to category 8 is 1, and the membership degree belonging to other categories is 0; when the deviation of a person's body surface temperature is 0.2℃, the membership degree of the deviation belonging to category 9 is 1, and the membership degree belonging to other categories is 0; when the deviation of a person's body surface temperature is 0.3℃, the membership degree of the deviation belonging to category 9 is 0.5, and the membership degree belonging to other categories is 0; when the deviation of a person's body surface temperature is 0.4℃, the membership degree of the deviation belonging to category 10 is 0.5, and the membership degree belonging to other categories is 0; when the deviation of a person's body surface temperature is 0.5℃, the membership degree of the deviation belonging to category 10 is 1, and the membership degree belonging to other categories is 0.

[0077] In step 204, a behavioral variable is determined, which indicates the change in the temperature adjustment of the vehicle's air conditioning system. The third membership function graph corresponding to the behavioral variable is determined. The third membership function graph is a function graph of the membership degree of the temperature adjustment deviation of the vehicle's air conditioning system belonging to different deviation ranges.

[0078] In one possible implementation, a behavioral variable is defined, which indicates the change in the regulated temperature of the vehicle's air conditioning system. A third membership function graph corresponding to the behavioral variable is also defined, which is a function graph showing the membership degree of the regulated temperature deviation of the vehicle's air conditioning system belonging to different deviation ranges. For example, a behavioral variable E is defined to indicate the change in the vehicle's air conditioning temperature, i.e., how many degrees the air conditioning temperature rises or falls, thus determining the range of the vehicle's air conditioning temperature deviation. Based on the consistency of the trends of the first and second relationships, the range of the vehicle's air conditioning temperature deviation is divided into a third reference number of air conditioning temperature difference categories according to the trends of the first or second relationships. For any air conditioning temperature difference category among the third reference number of categories, the trend of the third relationship between the air conditioning temperature deviation and the corresponding membership degree in that category is described, resulting in a third linguistic variable corresponding to that category. A third trigonometric function is established based on the correspondence between the multiple air conditioning temperature deviations and their corresponding membership degrees. A third membership function graph is obtained based on the third trigonometric function and the third linguistic variable. The horizontal axis of the third membership function graph represents the multiple air conditioning temperature deviations, and the vertical axis represents the membership degrees corresponding to the multiple air conditioning temperature deviations.

[0079] This application does not limit the range of temperature deviation for in-vehicle air conditioning settings; these settings can be based on experience or adjusted according to specific scenarios. Similarly, this application does not limit the number of third references; these settings can be based on experience or adjusted according to specific scenarios. For example, with a third reference number of 6, the temperature deviation range for in-vehicle air conditioning in category eleven is -7℃ to -4.5℃; for category twelve, it is -6℃ to -1℃; for category thirteen, it is -2℃ to 0℃; for category fourteen, it is 0℃ to 2℃; for category fifteen, it is 1℃ to 6℃; and for category sixteen, it is 4.5℃ to 7℃.

[0080] For example, the trend of the third relationship between the adjusted temperature deviation and the corresponding membership degree of the in-vehicle air conditioning system in any category of temperature difference adjustment is described, including using categories I (cooling), II (cooling), III (cooling), IV (heating), V (heating), and VI (heating) to describe the trend of the third relationship between the adjusted temperature deviation and the corresponding membership degree. The trend of the third relationship indicates the trend of the membership degree corresponding to the adjusted temperature deviation of the in-vehicle air conditioning system changing as the adjusted temperature deviation changes in any category of temperature difference adjustment. Figure 7 As shown, the temperature deviations of multiple in-vehicle air conditioners are used as the horizontal axis of the third membership function graph, and the membership degrees corresponding to the temperature deviations of multiple in-vehicle air conditioners are used as the vertical axis of the third membership function graph.

[0081] In one possible approach, a third membership function graph is obtained based on the third trigonometric function and the third linguistic variable. This graph includes a seventh triangle with a height of 1, formed by two equally wide regions symmetrical about the origin. The seventh triangle is an isosceles triangle, and there are six reference-numbered eighth triangles symmetrically arranged on its left and right sides. The height of each eighth triangle is 1, and the spacing between them is the third reference width. A half-ninth triangle is located outside the midpoint of the base of the outermost eighth triangle, partially overlapping with the outermost eighth triangle. The vertices of the ninth triangles extend a ray parallel to the coordinate axis, extending to infinity or infinitesimal on either side. The sixth reference number is the third reference number minus three. The range of the horizontal coordinates of the base of each trigonometric function corresponds to the range of ambient temperature deviation for each in-vehicle air conditioning temperature adjustment category.

[0082] exist Figure 7 In the graph, the temperature deviations of multiple air conditioners are used as the horizontal axis of the first membership function graph, and the membership degrees corresponding to the temperature deviations of multiple air conditioners are used as the vertical axis of the first membership function graph. Figure 7 The horizontal axis of the base of the first triangle from left to right corresponds to the temperature deviation range of the air conditioner in category 11, from -7℃ to -4.5℃. Within this range, the trigonometric function relationship between the air conditioner's temperature deviation and its membership in category 11 is linear. For example, within the horizontal axis range of -7℃ to -4.5℃, as the temperature deviation increases, the membership in category 1 decreases. Using the concept of "cooling down" to describe the third trigonometric function within the horizontal axis range of -7℃ to -4.5℃, we obtain the third membership function graph for this range.

[0083] Figure 7 The horizontal axis range of the base of the second triangle from left to right corresponds to the range of air conditioner temperature deviation in category 12, from -6℃ to -1℃. Within this range, the trigonometric function relationship between the air conditioner temperature deviation and its membership in category 2 is linear and consists of two parts. For example, within the horizontal axis range of -6℃ to -4℃, as the air conditioner temperature deviation increases, the membership in category 12 increases; conversely, within the horizontal axis range of -4℃ to -1℃, as the air conditioner temperature deviation increases, the membership in category 1 decreases. Using cooling method II to describe the third trigonometric function within the horizontal axis range of -6℃ to -1℃, we obtain the third membership function graph within this range.

[0084] Figure 7 The horizontal axis of the base of the first triangle from left to right corresponds to the temperature deviation range of the air conditioner in category thirteen, from -2℃ to -0℃. Within this range, the trigonometric function relationship between the air conditioner's temperature deviation and its membership in category thirteen is linear. For example, within the horizontal axis range of -2℃ to -0℃, as the temperature deviation increases, the membership in category one decreases. Using the concept of cooling (Ⅲ) to describe the third trigonometric function within the range of -2℃ to -0℃, we obtain the third membership function graph within this range.

[0085] Figure 7The horizontal axis range of the base of the first triangle from left to right corresponds to the temperature deviation range of the air conditioner in category fourteen, from 0℃ to 2℃. Within this range, the trigonometric function relationship between the air conditioner's temperature deviation and its membership in category fourteen is linear. For example, within the horizontal axis range of 0℃ to 2℃, as the temperature deviation increases, the membership in category one decreases. Using temperature rise IV to describe the third trigonometric function within the horizontal axis range of 0℃ to 2℃, we obtain the third membership function graph within this range.

[0086] Figure 7 The horizontal axis range of the base of the fourth triangle from left to right corresponds to the temperature deviation range of the air conditioner in category 15, from 1℃ to 6℃. Within this range, the trigonometric function relationship between the temperature deviation and its membership in category 4 is linear and consists of two parts. For example, within the range of 1℃ to 4℃, as the temperature deviation increases, the membership in category 15 increases; within the range of 4℃ to 6℃, as the temperature deviation increases, the membership in category 1 decreases. Using temperature rise V to describe the third trigonometric function within the range of 1℃ to 6℃, we obtain the third membership function graph within this range.

[0087] Figure 7 The horizontal axis range of the base of the fifth triangle from left to right corresponds to the temperature deviation range of the air conditioner in category sixteen, from 4.5℃ to 7℃. Within this range, the trigonometric function relationship between the air conditioner's temperature deviation and its membership in category sixteen is linear. For example, within the horizontal axis range of 4.5℃ to 7℃, as the temperature deviation increases, the membership in category five increases. Using the VI temperature rise parameter to describe the third trigonometric function within the range of 4.5℃ to 7℃, we obtain the third membership function graph for this range.

[0088] In step 205, based on the consistency of the changing trends of ambient temperature deviation, human body surface temperature deviation, and vehicle air conditioning temperature adjustment deviation in the first, second, and third membership function graphs, the first correspondence between the vehicle air conditioning control mode and the vehicle air conditioning temperature adjustment deviation in the third membership function graph is converted into a second correspondence between the vehicle air conditioning control mode and the ambient temperature deviation and human body surface temperature deviation in the first and second membership function graphs.

[0089] Specifically, based on the consistency of the changing trends of ambient temperature deviation, human body surface temperature deviation, and in-vehicle air conditioning temperature adjustment deviation in the first, second, and third membership function graphs, the first correspondence between the in-vehicle air conditioning control mode and the in-vehicle air conditioning temperature adjustment deviation in the third membership function graph is converted into a second correspondence between the in-vehicle air conditioning control mode and the ambient temperature deviation and human body surface temperature deviation in the first and second membership function graphs. This includes, but is not limited to: determining the first correspondence between the in-vehicle air conditioning control mode and the in-vehicle air conditioning temperature adjustment deviation in the third membership function graph based on the third membership function graph; and replacing the in-vehicle air conditioning temperature adjustment deviation in the first correspondence with the ambient temperature difference category and the human body surface temperature difference category to obtain the second correspondence.

[0090] In one possible implementation, the third language variables are Ⅰ cooling, Ⅱ cooling, Ⅲ cooling, Ⅳ heating, Ⅴ heating, and Ⅵ heating, and the first correspondence in the third membership function graph includes: Ⅰ cooling category in the third membership function graph corresponds to vehicle air conditioning control mode one; Ⅱ cooling category in the third membership function graph corresponds to vehicle air conditioning control mode two; Ⅲ cooling category in the third membership function graph corresponds to vehicle air conditioning control mode three; Ⅳ heating category in the third membership function graph corresponds to vehicle air conditioning control mode four; Ⅴ heating category in the third membership function graph corresponds to vehicle air conditioning control mode five; and Ⅵ heating category in the third membership function graph corresponds to vehicle air conditioning control mode six.

[0091] Since the cooling category I in the third membership function graph satisfies that the corresponding environmental temperature difference category includes the higher category and the corresponding personnel body surface temperature difference category includes the hot category, the control mode 1 of the in-vehicle air conditioning corresponding to the cooling category I in the third membership function graph satisfies that the corresponding environmental temperature difference category includes the higher category and the corresponding personnel body surface temperature difference category includes the hot category.

[0092] Since the cooling category II in the third membership function graph satisfies that the corresponding environmental temperature difference category includes the higher category and the corresponding personnel body surface temperature difference category includes the warm category, the control mode II of the in-vehicle air conditioning corresponding to the cooling category II in the third membership function graph satisfies that the corresponding environmental temperature difference category includes the higher category and the corresponding personnel body surface temperature difference category includes the warm category.

[0093] Since the cooling category Ⅲ in the third membership function graph satisfies either the corresponding ambient temperature difference category including the high category or the corresponding human body surface temperature difference category including the warm category, the control mode 3 of the in-vehicle air conditioning corresponding to the cooling category Ⅲ in the third membership function graph satisfies either the corresponding ambient temperature difference category including the high category or the corresponding human body surface temperature difference category including the warm category.

[0094] Since the IV temperature rise category in the third membership function graph satisfies either the corresponding ambient temperature difference category including the low category or the corresponding human body surface temperature difference category including the cool category, the control mode four of the in-vehicle air conditioning corresponding to the IV temperature rise category in the third membership function graph satisfies either the corresponding ambient temperature difference category including the low category or the corresponding human body surface temperature difference category including the cool category.

[0095] Since the V heating category in the third membership function graph satisfies that the corresponding ambient temperature difference category includes the lower category and the corresponding human body surface temperature difference category includes the cool category, then the control mode five of the in-vehicle air conditioning corresponding to the V heating category in the third membership function graph satisfies that the corresponding ambient temperature difference category includes the lower category or the corresponding human body surface temperature difference category includes the cool category.

[0096] Since the heating category VI in the third membership function graph satisfies that the corresponding ambient temperature difference category includes the lower category and the corresponding human body surface temperature difference category includes the cold category, the control mode VI of the in-vehicle air conditioning corresponding to the heating category VI in the third membership function graph satisfies that the corresponding ambient temperature difference category includes the lower category or the corresponding human body surface temperature difference category includes the cool category.

[0097] In step 206, a control strategy for controlling the vehicle air conditioning by means of the ambient temperature deviation and the temperature deviation of the human body surface is obtained according to the second correspondence.

[0098] The control strategies for the vehicle's air conditioning include, but are not limited to, controlling how much the air conditioning will heat up or cool down, the opening degree of the air vents, and the area where the air conditioning will blow air.

[0099] In one possible implementation, for control mode one, based on the cooling category I in the third membership function graph, the range of temperature deviation of the in-vehicle air conditioning in cooling category I is taken as the range of temperature reduction by the air conditioning in control mode one. Therefore, when the ambient temperature difference category includes the "higher" category and the corresponding human body surface temperature difference category includes the "hot" category, the air conditioning is controlled based on control mode one. At this time, the temperature adjustment range is large, the vent opening is set high, and the air blowing area is set to the foot area, ensuring the speed of temperature adjustment while reducing the interference of strong cold air on passengers.

[0100] For control mode two, based on the cooling category II in the third membership function graph, the range of temperature deviation of the in-vehicle air conditioning in cooling category II is used as the range for temperature reduction by the air conditioning in control mode one. Therefore, when the ambient temperature difference category includes the "higher" category and the corresponding body surface temperature difference category includes the "warm" category, the air conditioning is controlled based on control mode two. At this time, the temperature adjustment range is larger, the vent opening is set to medium, and the airflow area is set to the foot area, ensuring the speed of temperature adjustment while reducing the interference of strong cold air on passengers.

[0101] For control mode three, based on the cooling category III in the third membership function graph, the range of temperature deviation of the in-vehicle air conditioning in cooling category III is taken as the range of temperature reduction by the air conditioning in control mode three. Therefore, when the ambient temperature difference category includes the "high" category or the corresponding human body surface temperature difference category includes the "warm" category, the air conditioning is controlled based on control mode three. At this time, the temperature adjustment range is small, the vent opening is set to low, and there is no restriction on the air blowing area.

[0102] The control mode setting principle for raising the temperature is the same as that for lowering the temperature. For example, in control mode four, based on the IV temperature rise category in the third membership function graph, the range of temperature deviation of the in-vehicle air conditioning in category IV is used as the range for raising the temperature in control mode four. Therefore, when the ambient temperature difference category includes the "low" category or the corresponding body surface temperature difference category includes the "cool" category, the air conditioning is controlled based on control mode four. In this case, the temperature adjustment range is small, the vent opening is set low, and there is no restriction on the airflow area.

[0103] For control mode five, based on the V temperature rise category in the third membership function graph, the range of temperature deviation of the in-vehicle air conditioning in the V temperature rise category is taken as the range of temperature increase by the air conditioning in control mode five. Therefore, when the ambient temperature difference category includes the lower category and the corresponding human body surface temperature difference category includes the cool category, the air conditioning is controlled based on control mode five. At this time, the temperature adjustment range is large, the vent opening is adjusted to medium, and the air blowing area is set to the foot area, ensuring the speed of temperature adjustment while reducing the interference of strong hot air on passengers.

[0104] For control mode six, based on the VI temperature rise category in the third membership function graph, the range of temperature deviation of the in-vehicle air conditioning in the VI temperature rise category is taken as the range of temperature rise by the air conditioning in control mode six. Therefore, when the ambient temperature difference category includes the lower category and the corresponding human body surface temperature difference category includes the cold category, the air conditioning is controlled based on control mode six. At this time, the temperature adjustment range is large, the vent opening is set high, and the air blowing area is set to the foot area, ensuring the speed of temperature adjustment while reducing the interference of strong hot air on passengers.

[0105] In step 207, based on the control strategy, the target control mode corresponding to the currently acquired actual temperature inside the vehicle and the body surface temperature of the occupants is determined, and the vehicle air conditioning is controlled according to the target control mode.

[0106] Specifically, based on the control strategy, a target control mode is determined corresponding to the currently acquired actual temperature inside the vehicle and the body surface temperature of the occupants. The vehicle's air conditioning is then controlled according to the target control mode, including but not limited to: calculating the actual ambient temperature deviation based on the currently acquired actual temperature inside the vehicle, and calculating the actual body surface temperature deviation of the occupants based on the currently acquired body surface temperature. Based on the control strategy, the target control mode corresponding to the vehicle's air conditioning is determined by calculating the actual ambient temperature deviation and the actual body surface temperature deviation of the occupants.

[0107] For example, the actual ambient temperature deviation ΔT is calculated based on the currently acquired actual interior temperature Tk, and the actual occupant's body surface temperature deviation Δt is calculated based on the currently acquired occupant's body surface temperature tk. The control strategies corresponding to the actual ambient temperature deviation ΔT and the actual occupant's body surface temperature deviation Δt are determined, along with the target control mode for the vehicle's air conditioning. The air conditioning is controlled based on this target control mode, including controlling the degree of temperature increase or decrease, the air vent opening, and the airflow area. The next time the actual interior temperature Tk and the occupant's body surface temperature tk are acquired, the target control mode for the air conditioning is updated following the same process, achieving autonomous control of the vehicle's air conditioning.

[0108] The above method embodiment obtains a first membership function graph representing the membership degree of different deviation ranges of the ambient temperature deviation by performing fuzzy mapping on the actual temperature inside the vehicle. It also obtains a second membership function graph representing the membership degree of different deviation ranges of the body surface temperature deviation of the occupants by performing fuzzy mapping on the body surface temperature deviation of the occupants. Furthermore, it determines a third membership function graph representing the membership degree of different deviation ranges of the regulated temperature deviation of the vehicle's air conditioning system. Based on the consistency of the changing trends of the ambient temperature deviation, the occupant's body surface temperature deviation, and the regulated temperature deviation of the vehicle's air conditioning system in the first, second, and third membership function graphs, a control strategy for controlling the vehicle's air conditioning system using the ambient temperature deviation and the occupant's body surface temperature deviation is obtained. Then, based on this control strategy, the vehicle's air conditioning system is controlled according to the target control mode corresponding to the currently obtained actual temperature inside the vehicle and the occupants' body surface temperatures, achieving automatic control of the air conditioning system, making the control more accurate and efficient.

[0109] See Figure 8 This application provides a control device for an in-vehicle air conditioning system, the device comprising:

[0110] The acquisition module 801 is used to acquire the actual temperature inside the vehicle and the body surface temperature of the people inside the vehicle according to the reference frequency.

[0111] The calculation module 802 is used to calculate the ambient temperature deviation based on the actual temperature inside the vehicle, and to obtain multiple ambient temperature deviations. It also calculates the body surface temperature deviation of the occupants based on their body surface temperature, and to obtain multiple body surface temperature deviations of the occupants.

[0112] The first determining module 803 is used to determine the first membership function graph corresponding to multiple environmental temperature deviations and the second membership function graph corresponding to multiple personnel body surface temperature deviations. The first membership function graph is a function graph of the membership degree of multiple environmental temperature deviations belonging to different deviation ranges, and the second membership function graph is a function graph of the membership degree of multiple personnel body surface temperature deviations belonging to different deviation ranges.

[0113] The second determining module 804 is used to determine a behavioral variable, which indicates the change in the temperature regulation of the vehicle's air conditioning system, and to determine the third membership function graph corresponding to the behavioral variable. The third membership function graph is a function graph of the membership degree of the temperature regulation deviation of the vehicle's air conditioning system belonging to different deviation ranges.

[0114] The conversion module 805 is used to convert the first correspondence between the control mode of the in-vehicle air conditioner and the adjustment temperature deviation of the in-vehicle air conditioner in the third membership function diagram into a second correspondence between the different control modes of the in-vehicle air conditioner and the ambient temperature deviation and the human body surface temperature deviation in the first and second membership function diagrams, based on the consistency of the changing trends of the ambient temperature deviation, the human body surface temperature deviation and the adjustment temperature deviation of the in-vehicle air conditioner in the first membership function diagram and the third membership function diagram.

[0115] Module 806 is used to obtain, based on the second correspondence, a control strategy for controlling the in-vehicle air conditioning by controlling the deviation between ambient temperature and the deviation between human body surface temperature;

[0116] The control module 807 is used to determine the target control mode corresponding to the currently acquired actual temperature inside the vehicle and the body surface temperature of the occupants, based on the control strategy, and control the vehicle air conditioning according to the target control mode.

[0117] In one possible implementation, the calculation module 802 is used to determine the air conditioning usage mode based on the actual temperature inside the vehicle, the usage mode including cooling mode or heating mode; determine the in-vehicle reference temperature and the perceived reference temperature based on the air conditioning usage mode; subtract the obtained actual in-vehicle temperature from the in-vehicle reference temperature to obtain multiple ambient temperature deviations; and subtract the obtained body surface temperature of the occupants from the perceived reference temperature to obtain multiple occupant body surface temperature deviations.

[0118] In one possible implementation, the first determining module 803 is used to divide multiple ambient temperature deviations into a first reference number of ambient temperature difference categories according to their magnitude; for any ambient temperature difference category among the first reference number of ambient temperature difference categories, a linguistic variable is used to describe the changing trend of the first relationship between the ambient temperature deviation and the corresponding membership degree in any ambient temperature difference category, thereby obtaining a first linguistic variable corresponding to any ambient temperature difference category; a first trigonometric function is established based on the correspondence between multiple ambient temperature deviations and their corresponding membership degrees, and a first membership function graph is obtained based on the first trigonometric function and the first linguistic variable, wherein the horizontal axis of the first membership function graph represents multiple ambient temperature deviations, and the vertical axis of the first membership function graph represents the membership degree corresponding to multiple ambient temperature deviations.

[0119] In one possible implementation, the first determining module 803 is used to classify multiple personnel body surface temperature deviations into a second reference number of personnel body surface temperature difference categories according to their magnitude; for any personnel body surface temperature difference category in the second reference number of personnel body surface temperature difference categories, a linguistic variable is used to describe the changing trend of the second relationship between the personnel body surface temperature deviation and the corresponding membership degree in any personnel body surface temperature difference category, thereby obtaining a second linguistic variable corresponding to any personnel body surface temperature difference category; a second trigonometric function is established based on the correspondence between multiple personnel body surface temperature deviations and their corresponding membership degrees, and a second membership function graph is obtained based on the second trigonometric function and the second linguistic variable, where the horizontal axis of the second membership function graph represents the multiple personnel body surface temperature deviations, and the vertical axis of the second membership function graph represents the membership degrees corresponding to the multiple personnel body surface temperature deviations.

[0120] In one possible implementation, the second determining module 804 is used to determine the range of the temperature deviation of the vehicle air conditioning system; based on the consistency of the changing trends of the first and second relationships, the range of the temperature deviation of the vehicle air conditioning system is divided into a third reference number of temperature difference categories of the vehicle air conditioning system according to the changing trends of the first or second relationships; for any temperature difference category of the vehicle air conditioning system in the third reference number of temperature difference categories, a third relationship changing trend between the temperature deviation of the vehicle air conditioning system in any temperature difference category and the corresponding membership degree is described using linguistic variables, thereby obtaining a third linguistic variable corresponding to any temperature difference category of the vehicle air conditioning system; a third trigonometric function is established based on the correspondence between the temperature deviations of multiple vehicle air conditioning systems and the corresponding membership degrees, and a third membership function graph is obtained based on the third trigonometric function and the third linguistic variable, where the horizontal axis of the third membership function graph represents the temperature deviations of multiple vehicle air conditioning systems, and the vertical axis of the third membership function graph represents the membership degrees corresponding to the temperature deviations of multiple vehicle air conditioning systems.

[0121] In one possible implementation, the control module 807 is used to calculate the actual ambient temperature deviation based on the currently acquired actual temperature inside the vehicle, and to calculate the actual body surface temperature deviation of the occupants based on the currently acquired body surface temperature of the occupants; based on the control strategy, the target control mode corresponding to the vehicle air conditioning is determined by the calculated actual ambient temperature deviation and the actual body surface temperature deviation of the occupants.

[0122] The aforementioned device obtains a first membership function graph representing the membership degree of different deviation ranges of the ambient temperature deviation by performing fuzzy mapping on the actual temperature inside the vehicle corresponding to the ambient temperature deviation. It also obtains a second membership function graph representing the membership degree of different deviation ranges of the body surface temperature deviation of the occupants by performing fuzzy mapping on the body surface temperature deviation of the occupants. Furthermore, it determines a third membership function graph representing the membership degree of different deviation ranges of the regulated temperature deviation of the vehicle's air conditioning system. Based on the consistency of the changing trends of the ambient temperature deviation, the occupant's body surface temperature deviation, and the regulated temperature deviation of the vehicle's air conditioning system in the first, second, and third membership function graphs, a control strategy for controlling the vehicle's air conditioning system using the ambient temperature deviation and the occupant's body surface temperature deviation is obtained. Then, based on this control strategy, the vehicle's air conditioning system is controlled according to the target control mode corresponding to the currently obtained actual temperature inside the vehicle and the occupants' body surface temperatures, achieving automatic control of the air conditioning system, making the control more accurate and efficient.
