[0033] In this embodiment, a method for controlling an air conditioner in a vehicle running on an electronic device is provided. Figure 1 FIG. 1 is a flow chart of a method for controlling an air conditioner in a vehicle according to one embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0034] Step S10, obtaining current environmental information of the vehicle in the startup state;

[0035] The current environment information is used to represent the current in-cabin environment of the vehicle.

[0036] The vehicle's startup state can be understood as the state after the ignition or power-up, including but not limited to the vehicle's driving state and the vehicle's stationary state. When the vehicle is in motion, the air conditioner must be controlled to ensure the comfort of passengers and provide a comfortable riding environment. When the vehicle is in traffic, it may be intermittently stationary. During this state, a comfortable riding environment must still be provided to passengers.

[0037] Specifically, the vehicle's current environmental information, while in the startup state, is acquired through various vehicle sensors. These sensors include, but are not limited to, sunlight sensors, cabin temperature sensors, blowers, and evaporators. Current environmental information includes, but is not limited to, vehicle sunlight radiation information, cabin temperature information, air volume information for the air conditioner, and air conditioner temperature information. This current environmental information represents the vehicle's current cabin environment, specifically, the vehicle's current thermal environment. This information can be understood as representing the vehicle's current cabin temperature.

[0038] Since the temperature information inside the vehicle cabin can directly affect the passengers' riding experience, that is, the riding comfort, when providing passengers with a comfortable riding environment, it is necessary to take into account the vehicle's current environmental information, so as to more accurately determine the comfort of different parts of the passengers' body, and take targeted measures to improve the passengers' comfort.

[0039] Exemplarily, the sunlight radiation information of the vehicle in the started state, the vehicle's cabin temperature information, the air volume information of the air conditioner and the temperature information of the air conditioner are obtained based on the sunlight sensor, the vehicle's cabin temperature sensor, the blower and the evaporator, and the vehicle's current cabin environment is represented by the vehicle's sunlight radiation information, the vehicle's cabin temperature information, the air volume information of the air conditioner and the temperature information of the air conditioner.

[0040] Step S11, determining somatosensory parameters of multiple body parts of a vehicle passenger under current environmental information;

[0041] Because different parts of the human body perceive temperature differently, for example, the hands can withstand higher temperatures than the face. Furthermore, when the hands perceive higher or lower temperatures, the corresponding discomfort is less than when the face perceives higher or lower temperatures. Therefore, it is necessary to divide the human body into multiple parts and comprehensively improve the overall comfort level by considering the comfort level of each body part.

[0042] The multiple body parts include, but are not limited to, the head, face, neck, left shoulder, right shoulder, front chest, back chest, front abdomen, back abdomen, left arm, right arm, left hand, right hand, left leg, right leg, left foot, and right foot. Somatosensory parameters include, but are not limited to, the surface temperature of the passenger's body parts, the wind speed blowing against the surface of the body parts, and the radiant temperature of the sunlight shining on the surface of the body parts. Somatosensory parameters can be understood as thermal environment information for different body parts. Based on the somatosensory parameters, the comfort level, i.e., the comfort level, of different body parts in response to the current cabin environment information can be determined.

[0043] For example, the somatosensory parameters of the head, face, neck, left shoulder, right shoulder, front chest, back chest, front abdomen, back abdomen, left arm, right arm, left hand, right hand, left leg, right leg, left foot and right foot of the vehicle passengers are determined respectively under the current environmental information, so as to determine the comfort level of the above 17 body parts in the current cabin environment.

[0044] Step S12, determining a target body part from multiple body parts based on the somatosensory parameters;

[0045] In this case, under the current environmental information, the first comfort level perceived by the target body part is lower than the second comfort level perceived by body parts other than the target body part among the multiple body parts.

[0046] Step S12 can be understood as determining, based on the somatosensory parameters corresponding to each body part, the target body part with the lowest comfort level in the current cabin environment among the multiple body parts. Because the target body part has the lowest comfort level, a cooling or heating operation is performed on that target body part to improve its comfort level, thereby enhancing the overall comfort level of the passenger.

[0047] Specifically, when determining the target body part, the somatosensory parameters are used to determine the comfort level of each body part in the current cabin environment. A lower comfort level indicates a less comfortable experience for that body part. By comparing the comfort levels of each body part, a first comfort level with the lowest comfort level is determined. The body part corresponding to the first comfort level is the target body part. The comfort level of the body parts other than the target body part in the current environment is the second comfort level. It is understood that the first comfort level is lower than the second comfort level.

[0048] For example, the comfort level corresponding to each body part is determined based on the somatosensory parameters, and the comfort levels corresponding to each body part are ranked from highest to lowest. The body part with the lowest comfort level is designated as the first comfort level, and the body part corresponding to the first comfort level is the target body part requiring targeted air blowing. Thus, the target body part with the lowest comfort level can be accurately determined from multiple body parts based on the somatosensory parameters.

[0049] In addition, if the comfort levels of multiple body parts are the same, the target body part can be determined based on the priorities of the multiple body parts. Specifically, different body parts have different priorities. When the season outside the vehicle is spring or summer, the priorities of the above 17 body parts decrease in descending order according to their position in the human body. This means that when the season outside the vehicle is spring or summer, the priorities of the multiple body parts are, from large to small, head, face, neck, left shoulder, right shoulder, front chest, back chest, front abdomen, back abdomen, left arm, right arm, left hand, right hand, left leg, right leg, left foot, and right foot. When the season outside the vehicle is autumn or winter, the priorities of the above 17 body parts increase in descending order according to their position in the human body. This means that when the season outside the vehicle is autumn or winter, the priorities of the multiple body parts are, from small to large, head, face, neck, left shoulder, right shoulder, front chest, back chest, front abdomen, back abdomen, left arm, right arm, left hand, right hand, left leg, right leg, left foot, and right foot. For example, when the season outside the vehicle is autumn or winter, the somatosensory parameters are used to determine from multiple body parts that the comfort levels of the left shoulder and left leg are the same and are the lowest among the corresponding comfort levels of multiple body parts. Then, based on the priority sorting, it is determined that the priority of the left leg is greater than that of the left shoulder, and therefore the target body part is determined to be the left leg.

[0050] Step S13, controlling the air outlet of the vehicle's air conditioner to face the target body part.

[0051] The air vent is used to make the third comfort level perceived by the target body part higher than the first comfort level.

[0052] It is understood that a vehicle's air conditioner includes multiple air vents, each of which is used to output air (i.e., blow air) to lower or raise the ambient temperature within the vehicle cabin. Typically, different air vents correspond to different occupants, and it can be understood that the ambient temperature around each occupant is adjusted by the air volume output by the corresponding vent.

[0053] The direction of the air outlet of the vehicle's air conditioner can be changed. For example, when the target body part is the head, the air outlet of the air conditioner corresponding to the passenger is rotated toward the passenger's head, so that the air outlet of the air conditioner is directed toward the passenger's target body part, blowing air on the target body part, achieving the technical effect of cooling or heating the target body part, thereby improving the overall comfort of the passenger's body, and at the same time reducing the energy consumption of the air conditioner.

[0054] It can be understood that after the air outlet of the air conditioner is directed towards the target body part, the comfort perceived by the target body part will change. The third comfort perceived by the target body part after adjusting the air outlet is higher than the first comfort perceived by the target body part before adjusting the air outlet, that is, the comfort feeling of the target body part is improved, thereby improving the overall comfort of the human body of the passenger.

[0055] For example, by controlling the direction of the air outlet of the vehicle's air conditioner, the target body part can be cooled or heated in a targeted manner, thereby improving the comfort of the target body part and thereby improving the overall comfort of the passenger.

[0056] Therefore, by controlling the air outlet of the vehicle's air conditioner toward the target body part, the vehicle's air conditioner can specifically improve the comfort of the local body parts of the passengers, while improving the intelligence level of the air conditioner, thereby improving the comfort of the passengers in the vehicle.

[0057] Through the above steps, the vehicle's current environmental information is obtained when it is in the startup state. This current environmental information represents the vehicle's current cabin environment. Since different body parts of the occupant perceive different levels of comfort in the current cabin environment, somatosensory parameters of multiple body parts of the occupant under the current environmental information are determined, that is, the comfort levels corresponding to different body parts under the current environmental information are determined. A target body part is identified from the multiple body parts based on the somatosensory parameters. Under the current environmental information, a first comfort level perceived by the target body part is lower than a second comfort level perceived by other body parts other than the target body part. The target body part is the body part that the occupant experiences the most discomfort under the current environmental information. The air vent of the vehicle's air conditioner is controlled to be directed toward the target body part. The air vent is configured to cause the third comfort level perceived by the target body part to be higher than the first comfort level. This allows targeted air blowing, such as cooling or heating, to be performed on the target body part to improve its comfort level, thereby improving the overall comfort level of the occupant and reducing air conditioning energy consumption. The purpose of enabling the air outlet of the air conditioner in the vehicle to be targeted toward the local body parts of the passengers and blowing air toward the local body parts is achieved, and the technical effects of improving the intelligence level of the air conditioner, reducing the energy consumption of the air conditioner and improving the comfort of the passengers are achieved, thereby solving the technical problem in the related technology that the air outlet of the air conditioner cannot achieve targeted blowing, which leads to the intelligence level of the air conditioner.

[0058] Optionally, in step S10, obtaining the current environment information of the vehicle in the startup state may include the following execution steps:

[0059] The vehicle's current environmental information is obtained through vehicle sensors when the vehicle is in the started state.

[0060] Among them, the vehicle sensors include a sunlight sensor, an in-vehicle temperature sensor, an air volume sensor and an evaporator temperature sensor. The sunlight sensor is used to obtain the vehicle's sunlight radiation information in the current environmental information, the in-vehicle temperature sensor is used to obtain the vehicle's cabin temperature information in the current environmental information, the air volume sensor is used to obtain the blower's air volume information in the current environmental information, and the evaporator temperature sensor is used to obtain the evaporator's temperature information in the current environmental information.

[0061] Specifically, the sunlight sensor senses the amount of sunlight outside the vehicle in the current environment, measures the intensity of the sunlight's thermal radiation, and obtains the vehicle's sunlight radiation information in the current environment, thereby providing accurate sunlight radiation information for the current environment information of the vehicle when it is started.

[0062] The in-vehicle temperature sensor senses the temperature in the vehicle cabin under the current environment and obtains the in-vehicle temperature information under the current environment, thereby providing accurate in-vehicle temperature information for the current environment information when the vehicle is in the starting state.

[0063] The blower is used to deliver the air blown out by the air conditioner into the vehicle cabin. The air volume sensor obtains the blower air volume information of the vehicle in the current environment by sensing the air supply volume, thereby providing accurate blower air volume information for the current environment information when the vehicle is in the starting state.

[0064] The evaporator is used to exchange heat between the condensed gas and the outside air, liquefy and absorb heat to achieve the cooling effect. The evaporator temperature sensor senses the temperature of the evaporator and obtains the evaporator temperature information of the vehicle in the current environment, thereby providing accurate evaporator temperature information for the current environment information when the vehicle is started.

[0065] Therefore, the current environmental information of the vehicle when it is started is obtained through a variety of different types of vehicle sensors, thereby providing accurate sunlight radiation information, vehicle cabin temperature information, air volume information of the air conditioner, and temperature information of the air conditioner for the subsequent determination of the somatosensory parameters of multiple body parts of the vehicle passengers under the current environmental information, that is, providing accurate current environmental information, thereby ensuring the accuracy of the somatosensory parameters.

[0066] Optionally, in step S11, determining the somatosensory parameters of multiple body parts of the vehicle passenger under the current environment information may include the following execution steps:

[0067] The somatosensory parameters are determined based on the current environmental information and the target neural network model.

[0068] Among them, the target neural network model is obtained by training the initial neural network model based on the vehicle's environmental information samples and the somatosensory parameter samples of the passengers, and the environmental information samples correspond to the somatosensory parameter samples.

[0069] When training a neural network model, the initial neural network model is trained with environmental information samples and somatosensory parameter samples obtained through actual experiments or simulations to obtain a high-precision target neural network model. It can be understood that the environmental information samples correspond to the somatosensory parameter samples. When obtaining environmental information samples and somatosensory parameter samples, the vehicle's environmental information samples and the somatosensory parameter samples of the passengers can be determined based on the vehicle's environmental information under different working conditions and the somatosensory parameters of the passengers. Specifically, different working conditions can be understood as different sunlight radiation information of the vehicle, cabin temperature information of the vehicle, air volume information of the air conditioner, and temperature information of the air conditioner. Under different working conditions, somatosensory parameter samples are obtained through actual experiments or simulations.

[0070] By inputting the current environmental information into the target neural network model, the somatosensory parameters of multiple body parts are accurately output according to the target neural network model.

[0071] Therefore, the target neural network model is obtained through training, and the current environmental information is input into the target neural network model to obtain the somatosensory parameters of multiple body parts of the passenger under the current environmental information, thereby providing accurate somatosensory parameters of multiple body parts for the subsequent process of determining the target body part from multiple body parts based on the somatosensory parameters, thereby ensuring the accuracy of determining the target body part.

[0072] Optionally, the body-sensing parameters include the surface temperature of the passenger's body part, the wind speed blowing toward the surface of the body part, and the radiation temperature of the sunlight shining on the surface of the body part.

[0073] The somatosensory parameters are used to represent the comfort state of the surface of the passenger's body parts. Specifically, different body parts correspond to different somatosensory parameters, and the comfort state of the surface of different body parts can be determined based on the somatosensory parameters.

[0074] Optionally, in step S12, determining the target body part from multiple body parts based on the somatosensory parameters may include the following execution steps:

[0075] Determining comfort levels of multiple body parts based on somatosensory parameters;

[0076] When determining the comfort levels of multiple body parts, the comfort levels of the multiple body parts can be determined based on the somatosensory parameters and a comfort algorithm, such as the Zhang comfort algorithm. Specifically, because the comfort levels of different body parts are calculated differently, the comfort algorithm can determine the comfort levels of different body parts based on the somatosensory parameters corresponding to the different body parts.

[0077] For example, the comfort level of each body part is determined based on the surface temperature of the passenger's body part, the wind speed blowing toward the surface of the body part, and the radiant temperature of the sunlight shining onto the surface of the body part, thereby providing accurate and reliable comfort level for subsequently determining the target body part by comparing the comfort levels of multiple body parts, thereby ensuring the accuracy of the determined target body part.

[0078] determining the lowest comfort level among the comfort levels of the plurality of body parts as a first comfort level;

[0079] A body part corresponding to the first comfort level is determined as a target body part.

[0080] The comfort levels of multiple body parts are sorted from large to small, and the one with the lowest comfort level is the first comfort level, which corresponds to the target body part with the worst comfort level among the multiple body parts.

[0081] It is understood that since comfort is determined based on somatosensory parameters of multiple body parts, representing a person's comfort level in the current environment, the comfort levels of these multiple body parts are compared. The body part with the lowest comfort level is the least comfortable part for the occupant in the current environment and, therefore, the part requiring comfort adjustment. This part is therefore identified as the target body part. This provides precise directional information for the subsequent control of the vehicle's air vent orientation, thereby improving the intelligence of the air conditioning control system, thereby enhancing the comfort level of the target body part and, ultimately, the comfort level of the occupants in the current environment.

[0082] Optionally, in step S13, controlling the air outlet of the vehicle's air conditioner toward the target body part may include the following steps:

[0083] Identify the target body part and obtain the target location information;

[0084] determining a target rotation angle of a grille of the air conditioner corresponding to the target position information;

[0085] The air outlet is controlled toward the target body part according to the target rotation angle of the grille.

[0086] The target position information is used to indicate the position of the target body part in the current cabin environment.

[0087] A target body part is identified among multiple body parts, and the position of the target body part in the vehicle is obtained, namely the target information position. The target rotation angle of the air conditioner grille corresponding to the target position information is determined, and the air outlet is controlled to be directed toward the target body part according to the target rotation angle of the grille. Therefore, the rotation angle of the air conditioner grille is adjusted according to the target information position, so that the air outlet of the air conditioner is accurately directed toward the target body part, and the target body part is subjected to targeted cooling or heating operations, thereby improving the intelligence level of the air conditioning control system and the overall comfort of the passengers.

[0088] Specifically, the air vent positions of the air conditioner for different vehicle models vary, meaning the rotation angle of the air conditioner grille needs to be determined based on the actual conditions of each vehicle model. It is understood that, depending on the target body part, a certain angle range and rotation method can be set for the air conditioner grille's rotation. In an optional embodiment, when the target body part is the passenger's leg, due to the wide range of leg positions, the air conditioner grille can be set to rotate at an angle between the passenger's ankle and knee, with the rotation method being a cyclic swinging pattern within the aforementioned angle range, thereby catering to the different conditions of the target body part.

[0089] Therefore, the control method of the air conditioner in the vehicle proposed in the embodiment of the present invention can make the air outlet of the air conditioner blow towards the local body parts of the passengers in a targeted manner, thereby improving the local comfort of the passengers and the intelligence level of the air conditioner.
