[0002] If the driver's hand temperature is too low for a long time while driving, it may cause numbness of the driver's hands at the very least, and may even easily cause hand pain, rheumatoid arthritis and other diseases.

[0003] In order to solve the problem of air conditioning blowing on the hands, the current technology adopts a relatively simple and direct method, that is, avoiding the air conditioning blowing directly on the hands, but it also ignores the actual diverse needs of different users for hand warmth and coldness in different environments. In the existing technology, although there is a steering wheel heating, it is easy to cause inconsistent temperatures on the palm and back of the hand. In addition, although some steering wheels support the blowing function, they can only blow air at a fixed position, and cannot avoid or actively follow the hand to blow air, and the flexibility is very poor. Summary of the invention

[0006] In the above implementation, the current air-conditioning working mode, the target position of the hand and the hand temperature are comprehensively considered to control the air-conditioning air outlet direction, so that the driver's hands can obtain the best user experience. Through the above solution, the target position and hand temperature of the hand are identified and detected, and different air-conditioning air outlet control methods are used in different air-conditioning working modes to improve the temperature comfort of the driver's hands during driving.

[0007] According to at least one embodiment of the present disclosure, the air blowing direction of the air conditioner is controlled according to the air conditioner working mode, the target position and the hand temperature, including: when the air conditioner working mode is the heating mode, comparing the size relationship between the hand temperature and the temperature threshold; according to the comparison result of the hand temperature and the target position, the air outlet direction of the air conditioner is controlled.

[0008] In the above embodiment, the wind direction of the air-conditioning outlet is adjusted according to the detected hand temperature and the target position of the hand, so that the overall temperature in the car meets the comfort needs of the passengers while further improving the comfort effect of the driver's hands.

[0009] According to at least one embodiment of the present disclosure, the air outlet direction of the air conditioner is controlled according to the comparison result of the hand temperature and the target position, including: if the hand temperature is not greater than the temperature threshold, the air outlet direction of the air conditioner is controlled to avoid blowing toward the target position where the hand is located; if the hand temperature is greater than the temperature threshold, the air outlet direction of the air conditioner is controlled to avoid blowing toward the target position.

[0010] In the above embodiment, the wind direction of the air-conditioning outlet is adjusted according to the detected hand temperature and the target position of the hand, so that the overall temperature in the car meets the comfort needs of the passengers while further improving the comfort effect of the driver's hands.

[0011] According to at least one embodiment of the present disclosure, if the hand temperature is not greater than the temperature threshold, the air conditioner is controlled to blow air toward the target position where the hand is located, including: detecting whether the steering wheel is turned; if the steering wheel rotation duration is greater than the time threshold, and the steering wheel rotation angle is greater than the angle threshold, the air conditioner air outlet direction is controlled to follow the target position to adjust the blowing; if the steering wheel rotation duration is not greater than the time threshold, and / or the steering wheel rotation angle is not greater than the angle threshold, the air conditioner air outlet direction is not adjusted. In the above embodiment, the hand comfort is improved by following the blowing method, so that the driver can get a better driving experience.

[0012] According to at least one embodiment of the present disclosure, the angle threshold is 5°, and the time threshold is 2 seconds.

[0013] According to at least one embodiment of the present disclosure, the temperature threshold is set by: determining a default temperature threshold after identifying the identity of the driver holding the steering wheel; or, in response to the driver's setting request, setting the temperature threshold to a target temperature.

[0014] According to at least one embodiment of the present disclosure, the default temperature threshold is 35°C to 35.5°C.

[0015] In the above implementation, the diverse needs of users can be met. The vehicle can automatically set the default temperature threshold to avoid tedious operations by the user. The temperature threshold can also be manually set by the user to meet the personalized needs of the user. In addition, in the heating mode, the comparison result of the hand position and temperature is comprehensively considered to decide whether to blow air towards the hand or avoid blowing air away from the hand. The driver's hand comfort needs can be better met in the heating mode.

[0016] According to at least one embodiment of the present disclosure, the air conditioner operating mode also includes a cooling operating mode. According to the air conditioner operating mode, the target position and the hand temperature, the air conditioner blowing direction is controlled, including: when the air conditioner operating mode is the cooling mode, the air conditioner outlet direction is controlled to avoid blowing air at the target position.

[0017] In the above embodiment, when the air conditioner in the vehicle is turned on the cooling mode, in order to avoid the cold wind causing discomfort to the hands, the air outlet of the air conditioner is controlled to be directed away from the target area where the hands are located, thereby meeting the cooling demand in the vehicle and improving the comfort of the driver's hands.

[0019] In the above implementation, the hand position is identified and determined in a variety of ways. This can meet the need for detecting the hand position in different situations. Moreover, these two hand position identification methods can complement each other. When the infrared camera cannot accurately identify the hand position, the hand temperature can be used to identify the hand position. This improves the recognition accuracy.

[0030] The present disclosure is further described in detail below in conjunction with the accompanying drawings and examples. It is understood that the specific examples described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] In the prior art, although the steering wheel heating function can be enabled in winter, it can only heat the steering wheel, so that the user does not feel that the steering wheel is cold, but the ambient temperature felt by the user is still relatively low, which can easily cause inconsistent temperatures on the palms and backs of the hands in winter. In addition, although some steering wheels support the blowing function, they can only blow air at a fixed position, and cannot avoid or actively follow the hands with the blowing, and the flexibility is very poor. In particular, when the driver turns the steering wheel, the position of the hand on the steering wheel changes all the time, and blowing at a fixed position on the steering wheel cannot meet the driver's follow-up blowing needs. Therefore, there is a need for a solution that can effectively improve the temperature comfort of the driver's hands while driving a vehicle.

[0033] like Figure 1 Schematic diagram of an air conditioning air outlet control system illustrated in the embodiment of the present application. Figure 1 As can be seen in the figure, the system includes: air conditioner 1, infrared camera 2, steering wheel 3, temperature sensor 4. When air conditioner 1 is turned on, cooling mode or heating mode will be selected. After air conditioner 1 is turned on, the driver's hand is identified and the target position of the hand is determined, and the hand temperature is detected.

[0034] When detecting the temperature of the hand, the infrared camera 2 can be used to detect the temperature of the hand holding the steering wheel 3, or the temperature sensor 4 arranged on the steering wheel 3 can be used to detect the temperature of the hand. Among them, there can be at least one infrared camera 2, which can generally be set on the A-pillar inside the vehicle. The temperature sensors 4 are evenly arranged on the steering wheel 3, and can detect the temperature of the steering wheel 3 in real time.

[0035] When the temperature of the steering wheel 3 is detected, the temperature values ​​collected by the temperature sensors 4 at multiple different positions on the steering wheel 3 can be compared. Generally speaking, the position with the highest temperature is the position where the driver holds the hand. Therefore, by comparing the temperature values ​​of multiple sensors, it is possible to know where the driver holds the hand. Generally speaking, the highest temperature value collected when the steering wheel 3 heating is not turned on is the hand temperature.

[0036] After collecting the temperature value of the hand through the above two methods, the infrared camera 2 and the hand temperature can be further used to determine the target position of the hand on the steering wheel 3.

[0037] It should be noted that in the present application, the air outlet direction of the air conditioner 1 can be adjusted manually or automatically by a motor. For example, two motors for controlling the horizontal louvers and the longitudinal louvers of the air outlet are provided at the air outlet of each air conditioner 1. When the direction needs to be adjusted, the processor can send a control instruction to control the motor, thereby realizing the control and adjustment of the louvers of the air outlet of the air conditioner 1, and adjusting the air outlet direction, such as adjusting it to the direction facing the hand or avoiding the hand.

[0038] After knowing the target position of the hand, the air outlet direction of the air conditioner 1 can be further adjusted and controlled. In cooling mode, the air outlet of the air conditioner 1 is controlled to avoid the hand and blow air. In heating mode, when the hand temperature is lower than the temperature threshold, the air outlet direction is adjusted to blow air towards the hand to increase the hand temperature, so that the driver can get a better driving experience. When the hand temperature is not lower than the temperature threshold, the air outlet direction is adjusted to avoid blowing air from the hand to avoid hand sweating and cause poor hand comfort for the driver.

[0039] It is easy to understand that the system can comprehensively determine the air conditioning outlet adjustment control method according to different air conditioning working modes, hand temperature and target position, so that the driver can get a better driving experience in different working modes.

[0040] like Figure 2 A flowchart of an air conditioning air outlet control method provided in an embodiment of the present application. The method can be applied to a processor in a vehicle. Figure 2 The steps of the specific air conditioning air outlet control method are as follows.

[0041] Step 201: Determine the air conditioning working mode; the air conditioning working mode includes: heating mode.

[0042] In actual application, the driver can select the working mode of the air conditioner according to the external ambient temperature and environmental conditions, including: cooling mode and heating mode.

[0043] Generally speaking, when the ambient temperature is too high, the driver will choose the cooling mode to lower the ambient temperature in the car. Generally speaking, the air conditioning temperature in cooling mode will be 20℃ to 26℃, which is significantly lower than the human body temperature. If the cooling air of the air conditioner blows on the driver's hands for a long time, the hand temperature will quickly become too low, causing the driver to feel uncomfortable. It may also cause the driver to suffer from diseases such as hand arthritis.

[0044] When the ambient temperature is too low, the driver will select the heating mode to increase the ambient temperature inside the car. In the heating mode, the hand temperature can be quickly increased, making the driver feel comfortable. However, when the temperature is too high, it is easy to cause the driver's hands to sweat and cause discomfort, and it will also affect the driver's steering wheel.

[0045] Therefore, in order to provide the driver with a better driving experience, it is necessary to reasonably control and adjust the air outlet direction of the air conditioner according to the actual situation. The specific adjustment method and adjustment process can be found in the following embodiments.

[0046] Step 202: Detect the hand temperature using an infrared camera and / or a temperature sensor on the steering wheel.

[0047] like Figure 3a This is a schematic diagram of the structure of the infrared camera arrangement provided in the embodiment of the present application. Figure 3a As can be seen in the figure, the infrared camera is installed on the A-pillar near the driver's side of the car. This allows the infrared camera to detect the overall condition of the driver. For example, it can be used for face recognition to determine the driver's identity; it can also be used for hand recognition to determine the target position of the driver's hand on the steering wheel; it can also be used to detect the temperature of the hand to determine the driver's hand temperature.

[0048] In order to more accurately collect the temperature of the driver when holding the steering wheel, in addition to using an infrared camera, a temperature sensor arranged on the steering wheel can also be used for temperature detection. Figure 3b This is a schematic diagram of the temperature sensor arrangement provided in the embodiment of the present application. Figure 3b As can be seen in the figure, the sensors are evenly arranged on the steering wheel to detect the temperature at different positions on the steering wheel. Specifically, the number and density of sensors on the steering wheel can be selected according to actual needs. Figure 3b This is just an example. On the steering wheel, the temperature collected by the temperature sensor at the position where the driver does not hold the hand is the temperature of the steering wheel. On the steering wheel, the temperature collected at the position where the driver holds the hand is the hand temperature or the combined temperature of the steering wheel and the hand. For example, when the steering wheel heating is turned on, the temperature of the steering wheel is higher than the hand temperature after heating, so the temperature collected at this time is the combined temperature. Since the steering wheel dissipates heat slowly at the hand holding position, when the temperature sensor is used to detect the temperature, the temperature at the hand holding position is higher than the position without the hand holding position.

[0049] In addition, in order to obtain a more accurate hand temperature, the temperatures collected by the two methods can also be combined. For example, the hand temperature collected by the infrared camera and the hand temperature collected by the temperature sensor are averaged and used as the final hand temperature.

[0050] Through the above embodiments, the hand temperature in various situations can be collected more accurately.

[0051] Step 203: Determine the target position of the hand on the steering wheel using an infrared camera and / or the hand temperature.

[0052] In addition to collecting the hand temperature, it is also necessary to determine the target position of the hand on the steering wheel. The target position here can be understood as the position of the hand in the space inside the car. Then, the relative position relationship between the hand and each air-conditioning outlet in the space can be known, and the air-conditioning outlet can be controlled and adjusted.

[0053] When determining the target position of the hand in the interior space of the vehicle, the infrared camera can be used to collect images of the current interior space of the vehicle, and then the content of the collected images can be recognized to identify whether the driver's hand is therein, and if so, the target position of the driver's hand in the interior space of the vehicle can be further determined.

[0054] Of course, in some cases, the infrared camera cannot accurately identify the target position of the hand in the car space, and the hand temperature can also be used for detection. That is, the temperature values ​​detected by multiple temperature sensors on the steering wheel are used to comprehensively judge the position of the hand on the steering wheel.

[0055] Step 204: Control the blowing direction of the air conditioner according to at least two conditions of the air conditioner working mode, the target position and the hand temperature.

[0056] After the target position of the hand and the hand temperature are determined through the above embodiments, the air outlet of the air conditioner can be controlled in fundamentally different air conditioner working modes.

[0057] Simply put, in cooling mode, the air conditioning output is controlled to meet the driver's blowing needs while avoiding blowing on the driver's hands. In heating mode, it is necessary to decide whether to blow on the hands based on the temperature of the hands.

[0058] Through the above embodiment, the current air-conditioning working mode, the target position of the hand and the hand temperature are comprehensively considered to control the air-conditioning air outlet direction, so that the driver's hands can obtain the best user experience. Through the above scheme, the target position and hand temperature of the hand are identified and detected, and different air-conditioning air outlet control methods are used in different air-conditioning working modes to improve the temperature comfort of the driver's hands during driving.

[0059] In one or more embodiments of the present application, the air blowing direction of the air conditioner is controlled according to the air conditioning working mode, the target position and the hand temperature, including: when the air conditioning working mode is the heating mode, comparing the hand temperature with the temperature threshold; and controlling the air outlet direction of the air conditioner according to the comparison result of the hand temperature and the target position.

[0060] In actual applications, when the air conditioner is in heating mode, the air outlet of the air conditioner needs to be controlled according to the actual measured hand temperature. The default temperature threshold here is generally 35℃~35.5℃. In actual applications, users can select or set it according to their needs.

[0061] The specific implementation method can be to determine the default temperature threshold after identifying the driver holding the steering wheel. For example, when the driver gets on the car, the driver's identity is identified through an infrared camera, and the corresponding default temperature threshold is selected based on the identification result. The temperature threshold for male drivers is 35°C, and the temperature threshold for female drivers is 35.5°C. The driver does not need to go through tedious operations, so that different drivers can get the best posture experience The temperature threshold can also be set as a target temperature in response to the driver's setting request. For example, after the driver gets on the car, he sets the temperature threshold to a target temperature of 36°C through the human-computer interaction interface. Of course, it can also be set to a target temperature of 34°C. When the driver sets the temperature himself, he can set it as needed, but it is not allowed to exceed the upper and lower limits (for example, 20°C~40°C). If the set temperature threshold exceeds the upper and lower limits, a prompt message will be issued to remind the user to set a reasonable value within the upper and lower limits. Through the above embodiments, the diverse needs of users can be met, and the default temperature threshold can be automatically set by the vehicle to avoid tedious operations by the user. The temperature threshold can also be set manually by the user to meet the personalized needs of the user.

[0062] In heating mode, the hand temperature will be compared with the temperature threshold. When controlling the air outlet direction of the air conditioner, you can control it according to the target position of the hand. When you need to blow air on your hands, you can adjust the direction of the blinds by controlling the air outlet of the air conditioner so that the air discharged from the air outlet blows towards your hands. When you don't need to blow air on your hands, you can adjust the direction of the blinds by controlling the air outlet of the air conditioner so that the air discharged from the air outlet avoids your hands.

[0063] Based on the above embodiment, in the heating mode, the comparison result of the hand position and temperature is comprehensively considered to decide whether to blow air toward the hand or away from the hand, so as to better meet the driver's hand comfort requirements in the heating mode.

[0064] In one or more embodiments of the present application, the air outlet direction of the air conditioner is controlled according to the comparison result of the hand temperature and the target position, including: if the hand temperature is not greater than the temperature threshold, the air outlet direction of the air conditioner is controlled to blow toward the target position where the hand is located; if the hand temperature is greater than the temperature threshold, the air outlet direction of the air conditioner is controlled to avoid the target position.

[0065] In actual applications, when the hand temperature is collected through an infrared camera or a temperature sensor on the steering wheel, after comparison, it is found that the hand temperature is not greater than the temperature threshold. In other words, the current temperature of the driver's hands is low, and warm air needs to continue to be provided to the hands. The processor in the on-board electronic equipment can control the air outlet motor to adjust the direction of the shutters so that the air outlet direction of the air conditioner blows toward the target position where the hand is located. If the hand temperature is significantly lower than the temperature threshold, the hand can also be quickly warmed up by increasing the air volume and raising the temperature. As the hand temperature slowly rises, the air volume can be gradually reduced or the temperature can be lowered.

[0066] If, after comparison, it is found that the hand temperature is greater than the temperature threshold. In other words, if the current temperature of the driver's hand is appropriate or high, there is no need to continue to provide warm air to the hand. The processor in the on-board electronic equipment can control the air outlet motor to adjust the direction of the shutters so that the air outlet direction of the air conditioner avoids blowing air at the target position where the hand is located. In the case of avoiding blowing air to the hand, accurate avoidance can be achieved by detecting the target position. Of course, it is also possible not to detect the target position, turn on the wind sweeping or blow air to other areas of the steering wheel to achieve the effect of blowing air to the hand in non-real time.

[0067] For example, the hand temperature collected by the infrared camera is 37°C, and the temperature threshold is 35°C. At this time, the hand temperature is greater than the temperature threshold, and the air-conditioning outlet motor is controlled to adjust to other directions so that the wind direction blown out of the outlet avoids the target position or area where the hand is located. For another example, the hand temperature collected by the temperature sensor on the steering wheel is 30°C, and the temperature threshold is 35°C. At this time, the hand temperature is less than the temperature threshold, and the air-conditioning outlet motor is controlled to adjust to the direction of the hand so that the wind blown out of the outlet is directed toward the position of the hand. It should be noted that when the hand temperature collected by the infrared camera and the hand temperature collected by the temperature sensor are inconsistent, the average value of the two methods can be calculated.

[0068] Based on the above embodiment, the wind direction of the air-conditioning outlet is adjusted according to the detected hand temperature and the target position of the hand, so that the overall temperature in the car meets the comfort needs of the passengers while further improving the comfort effect of the driver's hands.

[0069] In one or more embodiments of the present application, if the hand temperature is not greater than the temperature threshold, the air conditioner is controlled to blow air toward the target position where the hand is located, including: detecting whether the steering wheel is turned; if the steering wheel rotation duration is greater than the time threshold, and the steering wheel rotation angle is greater than the angle threshold, the air outlet direction of the air conditioner is controlled to follow the target position to adjust the blowing; if the steering wheel rotation duration is not greater than the time threshold, and / or the steering wheel rotation angle is not greater than the angle threshold, the air outlet direction of the air conditioner is not adjusted.

[0070] In actual applications, the driver will turn the steering wheel as needed while driving. In order to better blow air to the hands, it can be decided whether to blow air to the hands according to the actual situation. That is, blow air along with the hands. Specifically, detect whether the steering wheel is turned (for example, it can be detected by the angle sensor on the steering column). If it is not turned, there is no need to adjust the air outlet direction of the air conditioner. If it is turned, it is necessary to further determine whether follow-up blowing is required. In a preferred embodiment, the angle threshold is 5° and the time threshold is 2 seconds.

[0071] When the steering wheel is turned, it is further determined whether the angle of rotation exceeds the angle threshold (for example, 5° or 10°), and whether the duration of the rotation exceeds the time threshold (for example, 2 seconds or 3 seconds). The angle threshold mentioned here can be set according to the effective coverage range of the wind blown out of the air outlet. That is, when the steering wheel rotation angle exceeds the angle threshold, the latest hand position will exceed the effective coverage range of the warm air. Consider adjusting the air outlet direction. If the rotation angle is relatively small and does not exceed the angle threshold, it means that the hand has always been within the effective coverage range of the warm air. At this time, the air outlet direction does not need to be adjusted.

[0072] In addition to considering the steering wheel rotation angle, the duration of the steering wheel rotation also needs to be considered. If the steering wheel rotation duration is not greater than the time threshold, for example, the driver turns around at the intersection, a quick adjustment is required, and the driver's hands will quickly turn the steering wheel. In this case, the air outlet direction does not need to be adjusted, because the target position changes rapidly and frequently, and the air outlet motor adjustment speed cannot meet the needs of rapid adjustment. In addition, since the adjustment duration is relatively short, the hand temperature will not drop significantly if the air is not blown for a short period of time. Therefore, adjustments can be made according to the target position after the steering wheel turns stably or after a period of time.

[0073] Based on the above embodiments, the hand comfort is improved by following the blowing method, so that the driver can get a better driving experience.

[0074] In one or more embodiments of the present application, when the steering wheel has a steering wheel heating function, an infrared camera and / or the temperature of the hand are used to determine the target position of the hand on the steering wheel, including: when the steering wheel heating is not turned on, the infrared camera is used to identify the hand and determine the target position of the hand on the steering wheel; when the steering wheel heating is turned on, if the infrared camera cannot identify the target position, the temperature sensor arranged on the steering wheel is used to detect the highest temperature position on the steering wheel as the target position.

[0075] In actual applications, some vehicle steering wheels have a steering wheel heating function. When the steering wheel heating is turned on, the high temperature of the steering wheel generates heat radiation, which affects the infrared camera's ability to recognize the hand temperature and the target position of the hand. Or, due to the high overall temperature in the car after being exposed to the sun in summer, the infrared camera cannot accurately identify or work, resulting in an inability to accurately find the target position of the hand. At this time, the steering wheel temperature collected by the temperature sensor can be used to determine the position of the hand on the steering wheel.

[0076] It should be noted that after turning on the steering wheel heating function, the steering wheel at the hand holding position dissipates heat slowly. When the temperature is measured using the temperature sensor, the temperature at this position is the highest. Therefore, by comparing the temperature values ​​collected by each temperature sensor, the position with the highest temperature value, which is the target position of the hand holding, can be found. This method will not be affected by other factors such as ambient temperature when finding the target position.

[0077] If the steering wheel heating is not turned on, or the infrared camera can accurately find the target position of the hand, the infrared camera can be used to identify the hand and then determine the target position of the hand on the steering wheel.

[0078] Based on the above embodiments, the hand position can be identified and determined in a variety of ways. It can meet the detection requirements of the hand position in different situations. Moreover, these two hand position identification methods can complement each other. When the infrared camera cannot accurately identify the hand position, the hand temperature can be used to identify the hand position. Improve the recognition accuracy.

[0079] In one or more embodiments of the present application, the air blowing direction of the air conditioner is controlled according to the air conditioning working mode, the target position and the hand temperature, including: when the air conditioning working mode is the cooling mode, the air outlet direction of the air conditioner is controlled to avoid blowing air at the target position.

[0080] When the vehicle's air conditioner is in cooling mode, in order to prevent the cold wind from causing discomfort to the hands, the air outlet of the air conditioner is controlled to be away from the target area where the hands are located, so as to meet the cooling needs in the car while improving the comfort of the driver's hands. However, in some scenarios, if passengers need cold air to cool down, the shutter swing wind sweeping mode can be turned on, but the swing range can be limited to before the blowing hand position.

[0081] For ease of understanding, the following will be described by way of specific examples. Figure 4 A schematic diagram of a flow chart of air-conditioning outlet control provided in an embodiment of the present application. Figure 4 As can be seen in the figure, the current air conditioning working mode of the vehicle is first determined, and the hand temperature is collected using an infrared camera or a temperature sensor. Further, the target position of the hand in the vehicle is determined.

[0082] When the vehicle's air conditioning operating mode is in cooling mode, after identifying the target position of the hand in the vehicle, the air conditioning is controlled to blow air away from the hand. For example, the air sweeping range can be limited.

[0083] When the vehicle's air conditioning is in heating mode, the temperature of the hand is detected and the position of the hand is identified. When the hand temperature is greater than the temperature threshold, the air conditioning is controlled to avoid blowing air at the hand position.

[0084] When the hand temperature is not greater than the temperature threshold, the air conditioner direction is adjusted to blow air toward the target position of the hand. If the driver turns the steering wheel, it is determined whether the steering wheel rotation angle exceeds the angle threshold and whether the duration exceeds the time threshold. If both exceed, the air conditioner blows air following the hand movement. If not, the hand turns the steering wheel but the air conditioner air outlet direction is not adjusted.

[0085] In the above manner, the air outlet direction of the air conditioner is comprehensively controlled according to the air conditioner working mode, the target position of the hand, and the hand temperature, including blowing towards the hand or away from the hand, ensuring the comfort of the hand, so that the driver can get a better driving experience.

[0086] Figure 5 A schematic diagram of the structure of a vehicle provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the vehicle is equipped with on-board electronic equipment, and the on-board electronic equipment includes: a memory 501 and a processor 502.

[0087] The memory 501 is used to store computer programs and can be configured to store various other data to support operations on the vehicle-mounted electronic device. Examples of such data include instructions for any application or method used to operate on the vehicle-mounted electronic device, contact data, phone book data, messages, pictures, videos, etc.

[0088] Among them, the memory 501 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read only memory (EEPROM), erasable programmable read only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk or optical disk.

[0089] The processor 502 is coupled to the memory 501 and is used to execute the computer program in the memory 501 to determine the air conditioning working mode; the air conditioning working mode includes: heating mode; using an infrared camera and / or a temperature sensor on the steering wheel to detect the hand temperature; using the infrared camera and / or the hand temperature to determine the target position of the hand on the steering wheel; controlling the air blowing direction of the air conditioner according to at least two conditions of the air conditioning working mode, the target position and the hand temperature.

[0090] Processor 502 is used to compare the hand temperature with the temperature threshold when the air conditioner is in heating mode; and control the air outlet direction of the air conditioner according to the comparison result of the hand temperature and the target position.

[0091] Processor 502 is used to control the air outlet direction of the air conditioner to avoid blowing towards the target position where the hand is located if the hand temperature is not greater than the temperature threshold; if the hand temperature is greater than the temperature threshold, control the air outlet direction of the air conditioner to avoid blowing towards the target position.

[0092] Processor 502 is used to detect whether the steering wheel is turned; if the duration of the steering wheel rotation is greater than the time threshold, and the steering wheel rotation angle is greater than the angle threshold, the air outlet direction of the air conditioner is controlled to follow the target position to adjust the blowing; if the duration of the steering wheel rotation is not greater than the time threshold, and / or the steering wheel rotation angle is not greater than the angle threshold, the air outlet direction of the air conditioner is not adjusted.

[0093] The processor 502 is used to determine a default temperature threshold after identifying the identity of the driver holding the steering wheel; or, in response to a setting request from the driver, set the temperature threshold to a target temperature.

[0094] Processor 502 is used to control the air outlet direction of the air conditioner to avoid blowing air at a target position when the air conditioner working mode is a cooling mode.

[0095] Processor 502 is used to use an infrared camera to recognize hands and determine the target position of the hands on the steering wheel when the steering wheel heating is not turned on; when the steering wheel heating is turned on, if the infrared camera cannot recognize the target position, the temperature sensor arranged on the steering wheel detects the highest temperature position on the steering wheel as the target position.
