[0066] To make the technical solution and advantages of this application clearer, the embodiments of this application will be described in further detail below.

[0067] The terms "first," "second," "third," and "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0068] It should be noted that all information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.), and signals involved in this application have been authorized by the user or fully authorized by all parties, and the collection, use, and processing of related data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the body temperature information and facial information involved in this application were obtained with full authorization.

[0069] Figure 1 This is a schematic diagram of a vehicle air conditioning control system provided in an embodiment of this application. See also... Figure 1 The system includes: a control device 101, an air conditioning system 102, an outside temperature sensor 103, an inside temperature sensor 104, and an inside camera 105. The outside temperature sensor 103, the inside temperature sensor 104, the inside camera 105, and the air conditioning system 102 are all electrically connected to the control device 101.

[0070] In this embodiment, the outside temperature sensor 103 and the inside temperature sensor 104 detect the outside and inside temperatures of the vehicle, respectively, and send the detected temperatures, namely the first temperature and the second temperature, to the control device 101. The control device 101 determines whether the first temperature and the second temperature meet a first preset condition. If the first preset condition is met, the control device 101 sends a third control command to the in-vehicle camera 105. Based on the third control command, the in-vehicle camera 105 collects the driver's body temperature information and the passenger's body temperature information, and sends the driver's body temperature information and the passenger's body temperature information to the control device 101. Based on the driver's body temperature information and the passenger's body temperature information, the control device 101 determines the first air conditioning temperature and the second air conditioning temperature corresponding to the driver and the passenger, respectively, and then controls the air conditioning system 102 based on the first air conditioning temperature and the second air conditioning temperature.

[0071] The air conditioning system 102 includes an air conditioning controller and an air conditioner. The control device 101, the air conditioning controller and the air conditioner are electrically connected in sequence. The control device 101 sends a first control command to the air conditioning controller based on a first air conditioner temperature and a second air conditioner temperature. The air conditioning controller controls the air conditioner based on the first control command.

[0072] The air conditioning controller can control at least one of the following motors based on a first control command: the air duct motor 106, the driver's side air duct manifold motor 107, and the passenger side air duct manifold motor 108. The air conditioning controller can also control the ventilation mode based on the humidity at the windshield and the left and right front door windows. Accordingly, the system also includes: the air duct motors 106, the driver's side air duct manifold motor 107, the passenger side air duct manifold motor 108, and at least one humidity sensor 109. The air duct motors 106 include a driver's side air duct motor, a passenger side air duct motor, and a rear air duct motor. All air duct motors 106, the driver's side air duct manifold motor 107, and the passenger side air duct manifold motor 108 are electrically connected to the air conditioning system 102, and at least one humidity sensor is electrically connected to the control device 101.

[0073] It should be noted that the number of the outside temperature sensor 103, the inside temperature sensor 104, and the inside camera 105 can be one or more, and there is no specific limitation. For the outside temperature sensor 103, if there are multiple sensors, the control device 101 can determine that the average outside temperature detected by the multiple sensors 103 is a first temperature. For the inside temperature sensor 104, if there are multiple sensors, the control device 101 can determine that the average inside temperature detected by the multiple sensors 104 is a second temperature. For the inside camera 105, if there are multiple cameras, the multiple cameras 105 can respectively collect the driver's body temperature information corresponding to the driver's area and the body temperature information of passengers corresponding to other areas, and send the driver's body temperature information and the passengers' body temperature information to the control device 101.

[0074] The in-vehicle camera 105 can be a camera with temperature detection capabilities to collect the body temperature information of the driver and passengers. The passenger's body temperature information may include at least one of the body temperature information of the front passenger in the front passenger area and the body temperature information of passengers in the rear passenger area; this is not specifically limited. Of course, if there are no passengers in the vehicle, the in-vehicle camera 105 can only collect the driver's body temperature information and send it to the control device 101. Based on the driver's body temperature information, the control device 101 determines the first air conditioning temperature corresponding to the driver, and then controls the air conditioning system 102 based on the first air conditioning temperature.

[0075] In this embodiment, the control device 101 can be a vehicle controller, an on-board host, or a domain controller; no specific limitation is made thereto. The vehicle can be a gasoline vehicle, a pure electric vehicle, or a hybrid vehicle; no specific limitation is made thereto.

[0076] The electrical connection can be either a cable connection or a wireless connection; this embodiment does not specifically limit the type of connection. If the electrical connection is a cable connection, the outside temperature sensor 103, the inside temperature sensor 104, and the inside camera 105 can be connected via CAN (Controller Area Network) signal lines. If the electrical connection is a wireless connection, the connection method can be a wireless local area network or a WiFi (Wireless Fidelity) network connection.

[0077] Figure 2 This is a flowchart of a vehicle air conditioning control method provided in an embodiment of this application, executed by a control device. See also... Figure 2 The method includes:

[0078] Step 201: Control the device to obtain the first temperature and the second temperature.

[0079] The first temperature is the temperature outside the vehicle, and the second temperature is the temperature inside the vehicle.

[0080] The control device acquires the first temperature sent by the outside temperature sensor and the second temperature sent by the inside temperature sensor.

[0081] The number of outside temperature sensors and inside temperature sensors can be one or more, without specific limitation. If there are multiple outside temperature sensors, the control device acquires the outside temperatures transmitted by the multiple sensors and determines the average of these temperatures as a first temperature. Similarly, if there are multiple inside temperature sensors, the control device acquires the inside temperatures transmitted by the multiple sensors and determines the average of these temperatures as a second temperature.

[0082] The control device can acquire the first and second temperatures when it detects high voltage on the vehicle's power supply. Alternatively, the control device can acquire the first and second temperatures upon receiving a temperature acquisition request from the terminal. In this embodiment, the timing of the control device acquiring the first and second temperatures is not specifically limited.

[0083] The process of the terminal sending a temperature acquisition request can be as follows: The target application is installed on the terminal. In response to logging into the target application, the terminal displays the air conditioning control interface, which shows the adaptive air conditioning temperature option. Upon detecting a trigger operation on the adaptive air conditioning temperature option, the terminal sends a temperature acquisition request to the control device. This terminal can be an in-vehicle terminal, a terminal used by the driver, or a terminal used by passengers; there is no specific limitation.

[0084] In this embodiment of the application, after the control device acquires the first temperature and the second temperature, it determines whether the first temperature and the second temperature meet the first preset condition. If the first preset condition is met, step 202 is executed.

[0085] The first preset condition can be set and changed as needed, and is not specifically limited. For example, the first preset condition is that the first temperature is greater than a first preset temperature, and the temperature difference between the first temperature and the second temperature is greater than a first preset difference. Another example is that the first preset condition is that the first temperature is less than a second preset temperature, and the temperature difference between the first temperature and the second temperature is less than a second preset difference. Here, the second preset temperature is less than the first preset temperature.

[0086] The first and second preset temperatures can be set and changed as needed; for example, the first preset temperature can be 30℃ and the second preset temperature can be 15℃. The first and second preset differences can also be set and changed as needed; for example, the first preset difference can be 5℃ and the second preset difference can both be 5℃.

[0087] In this embodiment, when the first temperature is greater than the first preset temperature, and the temperature difference between the first temperature and the second temperature is greater than the first preset difference, it indicates that the temperature inside and outside the vehicle is high. In this case, the control device determines that the air conditioning system operates in cooling mode. When the first temperature is less than the second preset temperature, and the temperature difference between the first temperature and the second temperature is less than the second preset difference, it indicates that the temperature inside and outside the vehicle is low. In this case, the control device determines that the air conditioning system operates in heating mode.

[0088] Step 202: If the first temperature and the second temperature meet the first preset condition, the control device acquires the driver's body temperature information and the passenger's body temperature information.

[0089] When the first temperature and the second temperature meet the first preset condition, the control device sends an acquisition request to the in-vehicle camera. Based on the acquisition request, the in-vehicle camera collects the driver's body temperature information and the passenger's body temperature information, and sends the driver's body temperature information and the passenger's body temperature information to the control device.

[0090] The number of in-vehicle cameras can be one or more, with no specific limit. If there is only one in-vehicle camera, it can capture images of the driver's area, the passenger's area, and the rear seats.

[0091] If there are multiple in-vehicle cameras, these cameras can capture images of the driver's seat, passenger seat, and rear seats. In this case, the control device sends acquisition requests to each of the multiple in-vehicle cameras. For each in-vehicle camera, based on the received acquisition request, it collects the body temperature information of the corresponding person within its captured area and sends the collected body temperature information to the control device.

[0092] Since different in-vehicle cameras capture different areas, when an in-vehicle camera sends the collected body temperature information to the control device, it can also send the camera identifier or area identifier. In other words, in addition to receiving the body temperature information, the control device also receives the camera identifier or area identifier. Based on the camera identifier or area identifier, the control device can determine which area the body temperature information collected by the in-vehicle camera belongs to and which person's body temperature information it belongs to.

[0093] In this embodiment, the control device can also acquire the driver's facial information and the passenger's facial information. Accordingly, step 202 can be: if the first temperature and the second temperature meet a first preset condition, the control device acquires the driver's body temperature information and facial information, as well as the passenger's body temperature information and facial information. This process can be: the control device sends an acquisition request to the in-vehicle camera; based on the acquisition request, the in-vehicle camera collects the driver's body temperature information and facial information, as well as the passenger's body temperature information and facial information, and sends the driver's body temperature information and facial information, as well as the passenger's body temperature information and facial information, to the control device.

[0094] It should be noted that if there are multiple in-vehicle cameras, each in-vehicle camera sends a camera identifier or area identifier when sending the collected body temperature and facial information to the control device. In this way, the control device can determine which area and person the body temperature and facial information collected by the in-vehicle camera belongs to based on the camera identifier or area identifier.

[0095] Step 203: The control device determines the first air conditioning temperature corresponding to the driver based on the driver's body temperature information.

[0096] If the control device only acquires the driver's body temperature information, the control device can determine whether the driver's body temperature is greater than the preset body temperature based on the driver's body temperature information. If the body temperature is greater than the preset body temperature, the control device can determine the first air conditioning temperature corresponding to the driver's body temperature information based on the first correspondence between the pre-stored body temperature and the air conditioning temperature.

[0097] If the control device acquires the driver's body temperature and facial information, it can determine whether the driver's body temperature is higher than a preset temperature based on the body temperature information, and perform facial recognition on the driver based on the facial information. Based on the facial recognition results, it can determine whether the driver has any uncomfortable expressions or demeanor. If the driver's body temperature is higher than the preset temperature and the driver has any uncomfortable expressions or demeanor, it can determine the first air conditioning temperature corresponding to the driver's body temperature based on the first correspondence between body temperature and air conditioning temperature that is stored in advance.

[0098] In this embodiment, if the control device acquires the driver's body temperature and facial information, the control device can also determine the driver's age range based on the facial recognition results. If the driver's body temperature is higher than a preset temperature and the driver exhibits an uncomfortable expression or demeanor, a first air conditioning temperature corresponding to the driver is determined based on the second correspondence between body temperature, age range, and air conditioning temperature, along with the driver's body temperature and age range.

[0099] In this embodiment, even if drivers have the same body temperature, people of different ages have different physical conditions and different tolerances to hot and cold. Therefore, the driver's body temperature is combined with his / her age range to jointly determine the air conditioning temperature corresponding to the driver. This can improve the accuracy of determining the air conditioning temperature corresponding to the driver and provide a suitable temperature for drivers of different ages, thereby meeting the needs of drivers of different ages.

[0100] Step 204: The control device determines the second air conditioning temperature corresponding to the passenger based on the passenger's body temperature information.

[0101] If the control device only acquires the passenger's body temperature information, the control device can determine whether the passenger's body temperature is greater than the preset body temperature based on the passenger's body temperature information. If the body temperature is greater than the preset body temperature, the control device can determine the second air conditioning temperature corresponding to the passenger's body temperature information based on the first correspondence between the pre-stored body temperature and the air conditioning temperature.

[0102] If the control device acquires the passenger's body temperature and facial information, it can determine whether the passenger's body temperature is higher than a preset temperature based on the body temperature information, and perform facial recognition on the passenger based on the facial information. Based on the facial recognition results, it can determine whether the passenger has any uncomfortable expressions or demeanor. If the passenger's body temperature is higher than the preset temperature and the passenger has any uncomfortable expressions or demeanor, it can determine the second air conditioning temperature corresponding to the passenger's body temperature information based on the first correspondence between body temperature and air conditioning temperature that is stored in advance.

[0103] Similarly, the control device can also determine the passenger's age range based on facial recognition results. If a passenger's body temperature is higher than a preset temperature and the passenger exhibits an expression or demeanor of discomfort, the second air conditioning temperature corresponding to the passenger can be determined based on this second correspondence, the passenger's body temperature, and the age range.

[0104] Step 205: The control device determines the first air duct wind speed and the first manifold air intake amplitude at the driver's location based on the first air conditioning temperature.

[0105] The control device pre-stores a third correspondence between air conditioning temperature, air duct speed, and manifold air intake amplitude. Based on the third correspondence, the first air conditioning temperature, and the working mode of the air conditioning system, the control device determines the first air duct speed and the first manifold air intake amplitude at the driver's location.

[0106] The first air duct speed is the air duct speed corresponding to the air duct motor at the driver's position, and the first manifold air intake amplitude is the manifold air intake amplitude corresponding to the driver's side air duct manifold motor.

[0107] Step 206: The control device determines the second air duct wind speed and the second manifold air intake amplitude at the passenger's location based on the second air conditioning temperature.

[0108] Based on the third correspondence, the second air conditioning temperature, and the working mode of the air conditioning system, the control equipment determines the second air duct wind speed and the second manifold air intake amplitude at the passenger's location.

[0109] The passengers are defined as follows: First, the passenger is the front passenger, and / or the rear passenger. If the passenger is the front passenger, the second air duct speed is the air duct speed corresponding to the air duct motor at the front passenger's location, and the second manifold air intake amplitude is the manifold air intake amplitude corresponding to the front passenger's air duct manifold motor. If the passenger is a rear passenger, the second air duct speed is the air duct speed corresponding to the air duct motor at the rear passenger's location, and the second manifold air intake amplitude is the manifold air intake amplitude corresponding to the rear passenger's air duct manifold motor. If the passengers are both the front passenger and a rear passenger, the second air duct speeds are the air duct speeds corresponding to the air duct motors at the front passenger's location and the rear passenger's location, respectively, and the second manifold air intake amplitudes are the manifold air intake amplitudes corresponding to the front passenger's air duct manifold motor and the rear passenger's air duct manifold motor, respectively.

[0110] In this embodiment, a driver's side air duct manifold motor and a passenger side air duct manifold motor are respectively installed in the driver's seat and passenger side positions. A rear air duct manifold motor may or may not be installed in the rear seats. The driver's side air duct manifold motor, passenger side air duct manifold motor, and rear air duct manifold motor allow outside air to enter the vehicle, connecting the outside and inside, thereby adjusting the interior temperature. If the passenger is a rear passenger and no air duct manifold motor is installed in the rear seats, the control device determines the second air duct speed at the rear passenger's location based on a third correspondence, a second air conditioning temperature, and the air conditioning system's operating mode. Furthermore, the number of rear passengers can be one or more, without specific limitation.

[0111] Step 207: The control device controls the air conditioning system based on the first duct wind speed, the first manifold air intake amplitude, the second duct wind speed, and the second manifold air intake amplitude.

[0112] The control device sends a first control command to the air conditioning system based on the first duct wind speed, the first manifold air intake amplitude, the second duct wind speed, and the second manifold air intake amplitude. The air conditioning system controls the driver's side duct motor and the driver's side duct manifold motor based on the first duct wind speed and the first manifold air intake amplitude in the first control command; and controls the duct motor and duct manifold motor at the passenger's location based on the second duct wind speed and the second manifold air intake amplitude in the first control command.

[0113] In addition to the first air duct speed, the first manifold air intake amplitude, the second air duct speed, and the second manifold air intake amplitude, the first control command may also carry a driver's position indicator, a passenger's position indicator, and an operating mode indicator. Correspondingly, when sending the first control command, the control device can associate the driver's position indicator, the first air duct speed, and the first manifold air intake amplitude, and associate the passenger's position indicator, the second air duct speed, and the second manifold air intake.

[0114] The air conditioning system includes an air conditioning controller and air conditioners. The control device can send a first control command to the air conditioning controller. The air conditioning controller determines the operating mode based on the operating mode identifier; it controls the driver's side air duct motor and driver's side air duct manifold motor based on the driver's position identifier, the first air duct speed, and the first manifold air intake amplitude; and it controls the air duct motor and air duct manifold motor at the passenger's location based on the passenger's position identifier, the second air duct speed, and the second manifold motor. If the passenger is a rear passenger and there is no air duct manifold motor in the rear, the air conditioning controller only needs to control the air duct motor at the passenger's location.

[0115] In this embodiment, the control device can determine the corresponding air conditioning temperature based on the body temperature information of users in different positions, and then control each air duct motor and / or air duct manifold motor through the air conditioning system to change the air duct speed and / or manifold air intake amplitude, so that users in different seats can feel comfortable, and there will be no situation where one user wants the air to blow upwards or the temperature to drop while another user disagrees.

[0116] In this embodiment, humidity sensors can be installed on the windshield and the left and right front door windows of the vehicle, respectively, to detect the humidity at the windshield, the left front door window, and the right front door window, and send the detected humidity to the control device. Correspondingly, the control device acquires the humidity of at least one window inside the vehicle, determines whether the humidity of any window is greater than a preset humidity, and if it determines that the humidity of any window is greater than the preset humidity, sends a second control command to the air conditioning system, which then controls the ventilation mode based on the second control command.

[0117] In this embodiment of the application, if the humidity of any part of the glass is greater than the preset humidity, the control device can control the ventilation mode through the air conditioning system. This can prevent water vapor on the glass from affecting driving and ensure the safety of driving.

[0118] It's important to note that in winter, due to prolonged driving or driver-related reasons, drivers may become drowsy, especially at high speeds, which is extremely dangerous. In this situation, the control system can activate the driver's side air duct motor via the air conditioning system, gradually reducing the airflow speed in the driver's side duct, and then activate the driver's side air manifold motor, gradually opening the air manifold to allow cold outdoor air to enter, thus helping the driver regain alertness. The corresponding process can be:

[0119] When the first temperature is lower than the second preset temperature, and the temperature difference between the first and second temperatures is less than the second preset difference, the control device acquires the driver's facial information. If the driver is determined to be drowsy based on the facial information, the control device determines the third air duct speed and the third manifold intake amplitude at the driver's location. Based on the third air duct speed and the third manifold intake amplitude, the control device controls the air conditioning system. Specifically, the third air duct speed is lower than the first air duct speed, and the third manifold intake amplitude is greater than the first manifold intake amplitude.

[0120] In this implementation, an in-vehicle camera periodically collects the driver's facial information and sends it to the control device. The control device determines whether the driver is drowsy based on this facial information. If the driver is drowsy, the system determines the third air duct speed and the third manifold air intake amplitude, and sends a fourth control command to the air conditioning system. This fourth control command carries the driver's seat position indicator, the third air duct speed, and the third manifold air intake amplitude. Based on the driver's seat position indicator, the third air duct speed, and the third manifold air intake amplitude, the air conditioning system controls the driver's seat air duct motor and the driver's seat air duct manifold motor respectively to reduce the driver's seat air duct speed and increase the driver's seat air duct manifold air intake amplitude.

[0121] In this embodiment, the control device periodically acquires the driver's facial information to determine whether the driver has regained consciousness and is in a conscious state. In this case, the control device can control the air conditioning system to resume heating and appropriately reduce the temperature and fan speed of the airflow to the driver's seat. Accordingly, this process can be as follows:

[0122] The control device acquires the driver's facial information again; if the driver is determined to be conscious based on the reacquired facial information, the third air conditioning temperature at the driver's location is determined; based on the third air conditioning temperature, the fourth air duct speed and the fourth manifold intake amplitude at the driver's location are determined; based on the fourth air duct speed and the fourth manifold intake amplitude, the air conditioning system is controlled. The third air conditioning temperature is lower than the first air conditioning temperature.

[0123] In this implementation, the control device determines whether the driver is awake based on the re-acquired facial information. If the driver is awake, it determines the difference between the first air conditioning temperature and the preset temperature to obtain the third air conditioning temperature. Based on the third correspondence and the third air conditioning temperature, it determines the fourth duct speed and the fourth manifold intake amplitude. Based on the fourth duct speed and the fourth manifold intake amplitude, it sends a fifth control command to the air conditioning system. The fifth control command carries the driver's seat position indicator, the fourth duct speed, and the fourth manifold intake amplitude. Based on the driver's seat position indicator, the fourth duct speed, and the fourth manifold intake amplitude, the air conditioning system controls the driver's seat duct motor and the driver's seat duct manifold motor respectively. The fourth duct speed is lower than the third duct speed, and the fourth manifold intake amplitude is greater than the third manifold intake amplitude.

[0124] It should be noted that if the driver becomes drowsy again, the above process will be repeated. That is, if the control system determines the driver is drowsy again within a preset time period based on facial information, it will adjust the airflow speed corresponding to the driver's side air duct motor and the manifold air intake amplitude corresponding to the driver's side air duct manifold motor to help the driver regain alertness. If the number of times the driver becomes drowsy exceeds a preset number based on facial information within the preset time period, the control system can prompt the front passenger to intervene, allowing the front passenger to assist and monitor the driver. Accordingly, this process can be:

[0125] If, within a preset time period, the number of times the driver becomes drowsy based on facial information exceeds a preset number, the control device acquires the facial information of the front passenger. If, based on the front passenger's facial information, the front passenger is determined to be drowsy, the device determines the fifth air duct speed and the fifth manifold intake amplitude at the front passenger's location. Based on the fifth air duct speed and fifth manifold intake amplitude, the air conditioning system is controlled. The air conditioning system, based on the fifth air duct speed, controls the front passenger air duct motor to reduce the front passenger air duct speed; based on the fifth manifold intake amplitude, it controls the front passenger air duct manifold motor to increase the front passenger air duct intake amplitude, allowing the front passenger to assist and monitor the driver. Specifically, the fifth air duct speed is lower than the second air duct speed, and the fifth manifold intake amplitude is greater than the second manifold intake amplitude.

[0126] In this implementation, the in-vehicle camera can periodically collect the facial information of the front passenger. The control device determines whether the front passenger is drowsy based on the facial information. If the control device determines that the front passenger is not drowsy, i.e. is awake, the control device can output a first voice message through the voice device to prompt the front passenger so that the front passenger can assist and monitor the driver.

[0127] If the control device determines that the front passenger is drowsy based on the front passenger's facial information, the control device can appropriately reduce the front passenger airflow speed and increase the front passenger airflow manifold intake amplitude to help the front passenger regain consciousness, thereby enabling the front passenger to assist and monitor the driver.

[0128] In this embodiment, when the driver is fatigued, the role of the front passenger can be fully utilized to assist and monitor the driver, thereby ensuring safety during driving. Of course, if there is no front passenger, rear passengers can also assist and monitor the driver; the specific process is the same as that of a front passenger assisting and monitoring the driver, and will not be repeated here.

[0129] Another point to note is that if the number of times the driver becomes drowsy within a preset time period exceeds a preset number, in order to ensure safety during driving, the control device can also determine the location of the nearest service area based on the vehicle's current location, determine the navigation route between the service area and the current location, display the navigation route, and output a second voice message to remind the driver to go to the service area to rest.

[0130] This application provides a vehicle air conditioning control method. The method acquires the body temperature information of the driver and passengers when the interior and exterior temperatures meet preset conditions; determines the corresponding air conditioning temperature for the driver and passengers based on their respective body temperature information; and controls the air conditioning system based on the corresponding air conditioning temperatures for the driver and passengers. Therefore, this method can control the air conditioning system to provide suitable air conditioning temperatures for the driver and passengers based on their respective body temperature information, ensuring that the air conditioning temperature meets the individual physical conditions of the driver and passengers, thereby satisfying the needs of different users.
