[0034] The following is a detailed description of the implementation details of the technical solution of the embodiment of the present application:

[0035] Figure 2 This is a flow chart of a vehicle air conditioning temperature control method shown in an exemplary embodiment of the present application. The vehicle air conditioning temperature control method can be executed by a computing processing device, which can be Figure 1 The vehicle controller 102 shown in FIG. Figure 2 As shown, the vehicle air conditioner temperature control method includes at least steps S210 to S240, which are described in detail as follows:

[0036] In step S210, the ambient temperature outside the vehicle and the air-conditioning temperature set inside the vehicle are obtained.

[0037] In one embodiment of the present application, the ambient temperature outside the vehicle is collected by a temperature sensor or other device. The air-conditioning temperature is determined by the air-conditioning setting instruction, which will not be described in detail here.

[0038] In this embodiment, when the air-conditioning temperature includes the current air-conditioning temperature, the target receiving temperatures of different body parts of the person in the vehicle are determined based on the ambient temperature and the current air-conditioning temperature; the target output temperature of each air outlet is determined according to the target receiving temperatures of different body parts; and the vehicle air conditioner is controlled to operate according to the target output temperature of each air outlet so that the receiving temperatures of different body parts reach their respective target receiving temperatures.

[0039] In this embodiment, when the air-conditioning temperature only includes historical air-conditioning temperatures, the latest air-conditioning temperature or the most frequently used air-conditioning temperature is selected from the historical air-conditioning temperatures as the target air-conditioning temperature, and the target receiving temperatures of different body parts of the people in the car are determined based on the ambient temperature and the target air-conditioning temperature; according to the target receiving temperatures of different body parts, the target output temperature of each air outlet is determined; according to the target output temperature of each air outlet, the vehicle air conditioner is controlled to work so that the receiving temperatures of different body parts reach their respective target receiving temperatures.

[0040] In this embodiment, the air-conditioning temperature set in the car can be the air-conditioning temperature manually set by the driver, the air-conditioning temperature manually set by the passenger, or the air-conditioning temperature automatically set according to the age and gender of the people in the car after determining the age and gender of the people in the car.

[0041] In step S220 , the target receiving temperatures of different body parts of the occupant of the vehicle are determined based on the ambient temperature and the air-conditioning temperature.

[0042] In this embodiment, the vehicle air conditioner is provided with multiple air outlets, and different body parts have corresponding air outlets, and different body parts have different target receiving temperatures. Different body parts of the occupant include the face, hands, feet, etc.

[0043] In this embodiment, the combination of the ambient temperature and the air-conditioning temperature has a one-to-one correspondence with the target received temperatures of different body parts of the vehicle occupant. The one-to-one correspondence between the combination of the ambient temperature and the air-conditioning temperature and the target received temperatures of different body parts of the vehicle occupant is obtained by pre-calibration.

[0044] In this embodiment, before determining the target receiving temperatures of different body parts of the occupants of the vehicle based on the ambient temperature and the air-conditioning temperature, the vehicle air-conditioning temperature control method also includes: controlling the vehicle air-conditioning to operate under different environmental conditions; and, when controlling the vehicle air-conditioning to operate under each environmental condition, scoring the comfort of different body parts by the testers; if under each environmental condition, the comfort scores of the testers for different body parts all reach the preset scoring range, then recording the receiving temperatures of the different body parts to obtain the target receiving temperatures of the different body parts under each environmental condition (that is, the combination of the ambient temperature and the air-conditioning temperature has a one-to-one correspondence with the target receiving temperatures of different body parts of the occupants of the vehicle).

[0045] In this embodiment, after obtaining the ambient temperature and the air-conditioning temperature, the ambient temperature is compared with the preset ambient temperature, and the air-conditioning temperature is compared with the preset air-conditioning temperature. If the ambient temperature is consistent with the preset ambient temperature and the air-conditioning temperature is consistent with the preset air-conditioning temperature, the target receiving temperature of different body parts under the combination of the preset ambient temperature and the preset air-conditioning temperature (i.e., under certain environmental conditions) is used as the target receiving temperature of different body parts of the people in the car.

[0046] In step S230, the target output temperature of each air outlet is determined according to the target receiving temperature of different body parts.

[0047] In this embodiment, there is a one-to-one correspondence between the body parts and the air outlets, and there is also a one-to-one correspondence between the target receiving temperature of the body parts and the target output temperature of their air outlets. The correspondence between the target receiving temperature of the body parts and the target output temperature of their air outlets is determined by pre-calibration. Here, the pre-calibration process is not limited.

[0048] In step S240, the vehicle air conditioner is controlled to operate according to the target output temperature of each air outlet, so that the receiving temperatures of different body parts reach their respective target receiving temperatures.

[0049] In this embodiment, the vehicle air conditioner is controlled to operate according to the target output temperature of each air outlet so that different parts of the body receive different temperatures, thereby achieving distributed temperature control of different parts of the body by the vehicle air conditioner, thereby improving the comfort of different parts of the body.

[0050] In one embodiment of the present application, before obtaining the air conditioning temperature set in the vehicle, the vehicle air conditioning temperature control method includes:

[0051] Collect facial images of people in the car.

[0052] In this embodiment, facial images of people in the car are collected by cameras and other equipment installed in the car.

[0053] The face image is input into the image recognition model to obtain the age and gender of the people in the car.

[0054] In this embodiment, the image recognition model is trained on a preset image recognition model based on sample facial images. The image recognition model is used to identify the age and gender of occupants of a vehicle. The preset image recognition model can be a neural network model, a convolutional network model, a residual network model, or the like.

[0055] Determine the air conditioning temperature based on the age and gender of the people in the car.

[0056] In this embodiment, when the ages of the people in the car are divided into 0-3 years old, 3-6 years old, 6-12 years old, 12-18 years old, 18-40 years old, 40-60 years old, 60-80 years old, etc., the ages of the people in the car include male and female, and the air-conditioning temperature can be controlled according to different age groups and different genders.

Whether a vehicle occupant issues a temperature adjustment command is determined by analyzing and determining an input signal by the vehicle air conditioner controller or signal processor. The analysis and determination process for determining whether a vehicle occupant issues a temperature adjustment command is not specifically defined herein.

[0060] If no temperature adjustment instruction is detected, the respective working modules are controlled to work according to the target output temperature of each air outlet, and the output temperature of each air outlet is detected until the output temperature of each air outlet reaches the respective target output temperature.

[0061] In this embodiment, a temperature detection device such as a temperature sensor is provided at each air outlet. The air temperature at the air outlet is detected by the temperature sensor, which is conducive to achieving precise control of the air temperature at the air outlet.

[0062] In this embodiment, the operating module is a cooling module or a heating module. Vehicle occupants can select cooling mode or heating mode based on their needs. For example, in summer, cooling mode is selected, and in winter, heating mode is selected. When the vehicle occupant selects cooling mode, the cooling module is controlled to operate. When the vehicle occupant selects heating mode, the heating module is controlled to operate.

[0063] If a temperature adjustment instruction is detected, the target receiving temperature of different body parts is adjusted based on the ambient temperature and the adjusted temperature value to obtain the target receiving temperature of different body parts based on the temperature adjustment. The target output temperature of each air outlet is adjusted according to the target receiving temperature of different body parts based on the temperature adjustment. The vehicle air conditioner is controlled to operate according to the target output temperature of each air outlet based on the temperature adjustment.

[0064] In this embodiment, if the vehicle air conditioner is controlled to work according to the target output temperature of each air outlet, and the person in the vehicle issues a temperature adjustment instruction again, the target output temperature of each air outlet based on the temperature adjustment is determined based on the ambient temperature and the adjusted temperature value, and the vehicle air conditioner is controlled to work according to the target output temperature of each air outlet based on the temperature adjustment, thereby improving the comfort of different body parts of the person in the vehicle.

[0065] In this embodiment, the process of controlling the vehicle air conditioner to operate based on the target output temperature after temperature adjustment at each air outlet is the same as the process of controlling the respective working modules to operate based on the target output temperature of each air outlet.

[0066] In one embodiment of the present application, the process of controlling the operation of each working module according to the target output temperature of each air outlet includes:

[0067] According to the target output temperature of each air outlet, the target heating temperature of the heating module in each working module and the target air outlet ratio of the air outlet module in each working module are determined.

[0068] In this embodiment, the sum of the target air outlet ratios of all air outlet modules is equal to a preset ratio threshold; the preset ratio threshold can be set to 1 or other thresholds, which are not specifically limited here.

[0069] In this embodiment, after the target output temperature of each air outlet is determined, the target heating temperature of the heating module in the respective working module of each air outlet is also determined; and, after the target output temperature of each air outlet is determined, the target air outlet ratio of the air outlet module in the respective working module of each air outlet is also determined.

[0070] In this embodiment, the target output temperature of each air outlet is mapped to the target heating temperature of the heating module in its respective working module, the target output temperature of each air outlet is mapped to the target air output ratio of the air outlet module in its respective working module, the mapping relationship between the target output temperature of each air outlet and the target heating temperature of the heating module in its respective working module is obtained by pre-calibration, and the mapping relationship between the target output temperature of each air outlet and the target air output ratio of the air outlet module in its respective working module is obtained by pre-calibration.

The increased airflow ratio of the air outlet modules corresponding to the facial air outlets is greater than the increased airflow ratio of the air outlet modules corresponding to the hand air outlets.

[0084] If the light intensity is less than or equal to the preset light intensity threshold, each heating module continues to be controlled to operate according to its respective target heating temperature, and each air outlet module continues to be controlled to operate according to its respective target air outlet ratio.

[0085] In this embodiment, when the light intensity is less than or equal to the preset light intensity threshold, the target air outlet ratio of each air outlet module is not adjusted.

[0086] In this embodiment, after obtaining the target output temperature of each air outlet, the target output temperature of each air outlet is further compensated by the light intensity, reducing the difficulty and workload of determining the target output temperature of each air outlet based on the ambient temperature, air-conditioning temperature and light intensity at the same time.

[0087] In one embodiment of the present application, after determining the target output temperature of each air outlet based on the target received temperature of different body parts, the vehicle air conditioner temperature control method further includes:

[0088] Get the air volume level set by the occupants of the vehicle.

[0089] In this embodiment, the air volume level set by the occupants of the vehicle is obtained by analyzing and judging the input signal through the controller or signal processor of the vehicle air conditioner. Here, the analysis and judgment process of the input signal is not specifically limited.

[0090] If the air volume gear includes the current air volume gear, the temperature compensation amount at the ambient temperature is determined based on the difference between the air volume of the current air volume gear and the preset air volume threshold; the target output temperature of each air outlet is adjusted according to the temperature compensation amount, and the vehicle air conditioner is controlled to operate according to the target output temperature of each air outlet after the air volume adjustment.

[0091] In this embodiment, the difference between the air volume of the current air volume gear and the preset air volume threshold has a corresponding relationship with the temperature compensation amount. The corresponding relationship between the difference between the air volume of the current air volume gear and the preset air volume threshold and the temperature compensation amount at different ambient temperatures is obtained by pre-calibration. Here, the calibration process of the corresponding relationship between the difference between the air volume of the current air volume gear and the preset air volume threshold and the temperature compensation amount at different ambient temperatures is not limited.

[0092] In this embodiment, the vehicle air conditioner is controlled to operate according to the target output temperature after the air volume is adjusted for each air outlet using a PID (Proportional Integral Derivative) control algorithm.

[0093] In this embodiment, the process of adjusting the target output temperature of each air outlet with the temperature compensation amount includes: calculating the sum of the temperature compensation amount and the target output temperature of each air outlet to obtain the target output temperature of each air outlet after adjustment based on the air volume.

[0094] If the air volume gear only includes historical air volume gears, the usage frequency of the historical air volume gears is sorted in descending order, and the air volume gear with the highest usage frequency is selected as the target gear. The temperature compensation amount at the ambient temperature is determined based on the difference between the air volume of the target gear and the preset air volume threshold. The target output temperature of each air outlet is adjusted with the temperature compensation amount, and the vehicle air conditioner is controlled to operate according to the target output temperature of each air outlet after adjustment based on the air volume.

[0095] In this embodiment, after determining the target output temperature for each air outlet, the target output temperature for each air outlet is further compensated based on the air volume output of the air volume level. This reduces the difficulty and workload of determining the target output temperature for each air outlet based on the ambient temperature, air conditioning temperature, and air volume output of the air volume level. Furthermore, when the air volume level is a historical air volume level, the historical air volume level is selected based on frequency of use, automatically adjusting the target output temperature for each air outlet. This reduces manual operation by vehicle occupants and meets their personal preferences.

[0096] In this embodiment, taking summer (≥28°C), spring and autumn (8-28°C), and winter (≤8°C) as examples, the probability distribution of historical wind speed levels is shown in Table 2:

[0100] In this embodiment, taking the ambient temperatures of 40°C, 30°C, -20°C, and -30°C as examples, the corresponding relationship between the difference (ΔBlow) between the air volume at the target gear and the preset air volume threshold and the temperature compensation amount is shown in Table 3:

[0104] In one embodiment of the present application, the process of controlling the vehicle air conditioner to operate according to the target output temperature after the air volume is adjusted at each air outlet includes:

[0105] Determine whether the air volume at the target gear meets the preset heat load requirement.

[0106] In this embodiment, the preset heat load requirement can be set according to actual conditions and is not specifically limited here.

[0107] If the air volume of the target gear meets the preset heat load requirement, the vehicle air conditioner will continue to operate according to the target output temperature of each air outlet adjusted based on the air volume.

[0108] In this embodiment, the vehicle air conditioner is controlled to operate according to the target output temperature after the air volume is adjusted for each air outlet using a PID control algorithm.

[0109] If the air volume of the target gear does not meet the preset heat load requirement, the next air volume gear is selected as the updated gear in the order of frequency of use, and the updated temperature compensation amount at the ambient temperature is determined based on the difference between the air volume of the updated gear and the preset air volume threshold; the target output temperature of each air outlet after the air volume adjustment is adjusted again with the updated temperature compensation amount, and the vehicle air conditioner is controlled to work according to the target output temperature of each air outlet after the air volume is adjusted again, and, in the process of controlling the vehicle air conditioner to work according to the target output temperature of each air outlet after the air volume is adjusted again, it is judged again whether the air volume of the updated gear meets the preset heat load requirement, until the selected historical air volume gear meets the preset heat load requirement.

[0110] In this embodiment, the difference between the air volume of the updated gear and the preset air volume threshold has a mapping relationship with the updated temperature compensation amount. Here, the correspondence between the difference between the air volume of the updated gear and the preset air volume threshold and the temperature compensation amount at different ambient temperatures is obtained by pre-calibration. Here, the calibration process of the correspondence between the difference between the air volume of the updated gear and the preset air volume threshold and the temperature compensation amount at different ambient temperatures is not limited.

[0111] In this embodiment, the process of re-adjusting the target output temperature of each air outlet based on the air volume adjustment by updating the temperature compensation amount includes: calculating the sum of the updated temperature compensation amount and the target output temperature of each air outlet based on the air volume adjustment, and obtaining the target output temperature of each air outlet based on the air volume adjustment.

[0112] In this embodiment, when the air volume of the target gear does not meet the preset heat load requirement, the next air volume gear is selected as the updated gear in the order of frequency of use. According to the difference between the air volume of the updated gear and the preset air volume threshold, and the target output temperature of each air outlet after the air volume is adjusted, the target output temperature of each air outlet after the air volume is adjusted again is obtained. Therefore, in the process of controlling the vehicle air conditioner according to the target output temperature of each air outlet after the air volume is adjusted again, the air volume of the updated gear not only meets the preset heat load requirement, but also meets the preference settings of the occupants in the vehicle, making it convenient for the occupants to use.

[0113] In one embodiment of the present application, before determining the target received temperatures of different body parts of the occupant based on the ambient temperature and the air conditioner temperature, the vehicle air conditioner temperature control method further includes:

[0114] Control the vehicle air conditioner to work under different environmental conditions.

[0115] In this embodiment, the environmental conditions include a preset ambient temperature and a preset air-conditioning temperature. The preset ambient temperature can be 40°C, 35°C, 30°C, -5°C, -10°C, -15°C, etc., and the preset air-conditioning temperature can be 18°C, 20°C, 22°C, 24°C, etc.

[0116] In addition, when controlling the vehicle air conditioner to work under each environmental condition, the testers score the comfort of different body parts; if under each environmental condition, the comfort scores of different body parts by the testers reach the preset score range, the receiving temperatures of different body parts are recorded to obtain the target receiving temperatures of different body parts under each environmental condition.

[0117] In this embodiment, the number of testers can be set according to actual conditions. Since different testers have different perceived temperatures, different testers are required to perform perceived temperature tests under different environmental conditions until the target receiving temperature of different body parts is reached under each environmental condition.

[0118] In this embodiment, by calibrating the target receiving temperatures of different body parts under each environmental condition in advance, after obtaining the ambient temperature and the air-conditioning temperature, the target receiving temperatures of different body parts of the people in the car can be determined directly through the comparison results of the ambient temperature with the preset ambient temperature, and the comparison results of the air-conditioning temperature with the preset ambient temperature.

[0119] Figure 3 is a flow chart of a vehicle air conditioning temperature control method shown in another exemplary embodiment of the present application, such as Figure 3As shown, the vehicle air conditioning temperature control method includes: (1) the occupant logs in to the account and calls the historical air volume level from the occupant's account data center; (2) the ambient temperature outside the vehicle and the occupant's temperature from the human-machine interface (HMI) are collected. (3) Based on the ambient temperature and the ambient temperature, the target receiving temperature of the window blowing in the main driver's area, the target receiving temperature of the face, the target receiving temperature of the hands, and the target receiving temperature of the feet are determined by looking up a table; Based on the ambient temperature and the ambient temperature, the target receiving temperature of the window blowing in the passenger's area, the target receiving temperature of the face, the target receiving temperature of the hands, and the target receiving temperature of the feet are determined by looking up a table; (4) Based on the target receiving temperature of the window blowing, the target output temperature of the air outlet for blowing the window is determined; Based on the target receiving temperature of the face, the target output temperature of the air outlet for blowing the face is determined; Based on the target receiving temperature of the hands, the target output temperature of the air outlet for blowing the hands is determined; Based on the target receiving temperature of the feet, the target output temperature of the air outlet for blowing the feet is determined; (5) The air volume gear with the highest frequency of use in the history is selected as the target gear, and based on the difference between the air volume of the target gear and the preset air volume threshold, the target output temperature of the air outlet for blowing the window, the target output temperature of the air outlet for blowing the face, and the target output temperature of the air outlet for blowing the hands are determined. The target output temperature of the air outlet and the target output temperature of the air outlet for blowing the feet are compensated, and the target output temperature of each air outlet is adjusted based on the air volume; (6) according to the target output temperature of each air outlet, the target heating temperature of the heating module in each working module and the target air outlet ratio of the air outlet module in each working module are determined; (7) each heating module is controlled to work according to its target heating temperature, and each air outlet module is controlled to work according to its target air outlet ratio; (8) the comfort of different body parts is evaluated by the air conditioning dummy test system. If the comfort score reaches the preset score range, each heating module is continued to be controlled to work according to its target heating temperature, and each air outlet module is continued to be controlled to work according to its target air outlet ratio; if the comfort score is not within the preset score range, the target receiving temperature of the window, the target receiving temperature of the face, the target receiving temperature of the hands, and the target receiving temperature of the feet are adjusted, and the target output temperature of each air outlet is adjusted accordingly, and the target output temperature of the heating module of each air outlet and the target air outlet ratio of the air outlet module of each air outlet are adjusted.

[0120] In this embodiment, while controlling each heating module to operate according to its respective target heating temperature, and controlling each air outlet module to operate according to its respective target air outlet ratio, the target output temperature of each air outlet can also be adaptively adjusted according to the light intensity outside the vehicle, the air conditioning circulation mode, the air humidity, etc., so that the receiving temperature of different body parts reaches their respective target receiving temperatures.

[0121] In this embodiment, the colors of different areas in the air-conditioning dummy test system represent different comfort scores. The corresponding relationship between the color of the color bar and the comfort score shows that red indicates a comfort score of at least 2 points, and the comfort evaluation is warm, hot, or very hot. Green indicates a comfort score between 0 and 1, and the comfort evaluation is slightly warm. In the transition range between green and blue, the comfort score is (-1)-0, and the comfort evaluation is neutral. In the blue range, the comfort score is (-4)-(-1), and the comfort evaluation is slightly cool, cool, cold, or very cold.

[0122] Figure 4 is a schematic diagram of summer comfort rating according to an exemplary embodiment of the present application. Figure 4 As shown, the horizontal axis represents temperature, and the vertical axis represents different body parts, where a represents right foot, b represents left foot, c represents right calf, d represents left calf, e represents right thigh, f represents left thigh, g represents right hand, h represents left hand, i represents right forearm, j represents left forearm, k represents right upper arm, l represents left upper arm, m represents upper back, n represents chest, o represents face, p represents head, and q represents whole body (whole). The comfort level corresponding to area 1 is evaluated as too cold and uncomfortable, the comfort level corresponding to area 2 is evaluated as cool but comfortable, the comfort level corresponding to area 3 is evaluated as neither cold nor hot and comfortable, the comfort level corresponding to area 4 is evaluated as warm but comfortable, and the comfort level corresponding to area 4 is evaluated as too hot and uncomfortable.

[0123] Figure 5 is a schematic diagram of winter comfort rating according to an exemplary embodiment of the present application. Figure 5 As shown, the horizontal axis represents temperature, and the vertical axis represents different body parts, where a represents right foot, b represents left foot, c represents right calf, d represents left calf, e represents right thigh, f represents left thigh, g represents right hand, h represents left hand, i represents right forearm, j represents left forearm, k represents right upper arm, l represents left upper arm, m represents upper back, n represents chest, o represents face, p represents head, and q represents whole body (whole). The comfort level corresponding to area 1 is evaluated as too cold and uncomfortable, the comfort level corresponding to area 2 is evaluated as cool but comfortable, the comfort level corresponding to area 3 is evaluated as neither cold nor hot and comfortable, the comfort level corresponding to area 4 is evaluated as warm but comfortable, and the comfort level corresponding to area 4 is evaluated as too hot and uncomfortable.

[0124] In this embodiment, each air outlet in the HVAC (Heating Ventilation and Air Conditioning) air conditioning system has an independently controlled actuator, and the damper actuator needs to be equipped with a DC servo motor, which performs feedback adjustment through the voltage of the DC servo motor to ensure that the output temperature of each air outlet reaches the target output temperature.

[0125] In this embodiment, the temperature control adjustment of three zones of the human body, namely the head, hands and feet, can be met, and the other parts are controlled nearby, so that people in the car will not feel hot head and cold feet, or cold head and hot feet, etc. due to the single control target of the air-conditioning adjustment system, which greatly improves the comfort of different parts of the human body.

[0126] In this embodiment, the car owner has a corresponding car computer account. After the car owner gets in the car, the air-conditioning controller automatically recognizes the car owner's information and calls the historical air volume gear. For example, the car owner has frequently used the 4th wind gear before. After the air conditioner automatically runs, the air conditioning adjustment system uses the 4th wind gear as the target gear's air volume. Based on the target gear's air volume, the output temperature of each air outlet is controlled. When the air volume of the target gear does not meet the preset heat load requirement, the next air volume gear is automatically selected as the updated gear in the order of frequency of use, thereby reducing adjustments due to personal preferences of people in the car, and greatly improving the frequency of use of the automatic adjustment function of the air conditioner, reducing user operations.

[0127] The following describes an embodiment of the device of the present application, which can be used to implement the vehicle air conditioning temperature control method in the above embodiment of the present application.

The device can be applied to Figure 1 The implementation environment shown is specifically configured in the vehicle controller 102. The device can also be applied to other exemplary implementation environments and specifically configured in other devices. This embodiment does not limit the implementation environment to which the device is applied.

[0129] like Figure 6 As shown, the exemplary vehicle air-conditioning temperature control device includes:

[0130] The temperature acquisition module 601 is used to obtain the ambient temperature outside the vehicle and the air-conditioning temperature set inside the vehicle.

[0131] The receiving temperature determination module 602 is used to determine the target receiving temperatures of different body parts of the occupant based on the ambient temperature and the air-conditioning temperature.

[0132] The output temperature determination module 603 is used to determine the target output temperature of each air outlet according to the target receiving temperature of different body parts.

[0133] The air conditioning control module 604 is used to control the vehicle air conditioning to operate according to the target output temperature of each air outlet, so that the receiving temperature of different body parts reaches their respective target receiving temperatures.

[0134] In one embodiment of the present application, the ambient temperature outside the vehicle is collected by a temperature sensor or other device. The air-conditioning temperature is determined by the air-conditioning setting instruction, which will not be described in detail here.

[0135] In this embodiment, when the air-conditioning temperature includes the current air-conditioning temperature, the target receiving temperatures of different body parts of the person in the vehicle are determined based on the ambient temperature and the current air-conditioning temperature; the target output temperature of each air outlet is determined according to the target receiving temperatures of different body parts; and the vehicle air conditioner is controlled to operate according to the target output temperature of each air outlet so that the receiving temperatures of different body parts reach their respective target receiving temperatures.

[0136] In this embodiment, when the air-conditioning temperature only includes historical air-conditioning temperatures, the latest air-conditioning temperature or the most frequently used air-conditioning temperature is selected from the historical air-conditioning temperatures as the target air-conditioning temperature, and the target receiving temperatures of different body parts of the people in the car are determined based on the ambient temperature and the target air-conditioning temperature; according to the target receiving temperatures of different body parts, the target output temperature of each air outlet is determined; according to the target output temperature of each air outlet, the vehicle air conditioner is controlled to work so that the receiving temperatures of different body parts reach their respective target receiving temperatures.

[0137] In this embodiment, the air-conditioning temperature set in the car can be the air-conditioning temperature manually set by the driver, the air-conditioning temperature manually set by the passenger, or the air-conditioning temperature automatically set according to the age and gender of the people in the car after determining the age and gender of the people in the car.

[0138] In this embodiment, the vehicle air conditioner is provided with multiple air outlets, and different body parts have corresponding air outlets, and different body parts have different target receiving temperatures. Different body parts of the occupant include the face, hands, feet, etc.

[0139] In this embodiment, the combination of the ambient temperature and the air-conditioning temperature has a one-to-one correspondence with the target received temperatures of different body parts of the vehicle occupant. The one-to-one correspondence between the combination of the ambient temperature and the air-conditioning temperature and the target received temperatures of different body parts of the vehicle occupant is obtained by pre-calibration.

[0140] In this embodiment, before determining the target receiving temperatures of different body parts of the occupants of the vehicle based on the ambient temperature and the air-conditioning temperature, the vehicle air-conditioning temperature control method also includes: controlling the vehicle air-conditioning to operate under different environmental conditions; and, when controlling the vehicle air-conditioning to operate under each environmental condition, scoring the comfort of different body parts by the testers; if under each environmental condition, the comfort scores of the testers for different body parts all reach the preset scoring range, then recording the receiving temperatures of the different body parts to obtain the target receiving temperatures of the different body parts under each environmental condition (that is, the combination of the ambient temperature and the air-conditioning temperature has a one-to-one correspondence with the target receiving temperatures of different body parts of the occupants of the vehicle).

[0141] In this embodiment, after obtaining the ambient temperature and the air-conditioning temperature, the ambient temperature is compared with the preset ambient temperature, and the air-conditioning temperature is compared with the preset air-conditioning temperature. If the ambient temperature is consistent with the preset ambient temperature and the air-conditioning temperature is consistent with the preset air-conditioning temperature, the target receiving temperature of different body parts under the combination of the preset ambient temperature and the preset air-conditioning temperature (i.e., under certain environmental conditions) is used as the target receiving temperature of different body parts of the people in the car.

[0142] In this embodiment, there is a one-to-one correspondence between the body parts and the air outlets, and there is also a one-to-one correspondence between the target receiving temperature of the body parts and the target output temperature of their air outlets. The correspondence between the target receiving temperature of the body parts and the target output temperature of their air outlets is determined by pre-calibration. Here, the pre-calibration process is not limited.

[0143] In this embodiment, the vehicle air conditioner is controlled to operate according to the target output temperature of each air outlet so that different parts of the body receive different temperatures, thereby achieving distributed temperature control of different parts of the body by the vehicle air conditioner, thereby improving the comfort of different parts of the body.
