In the present embodiment, a method for controlling an air conditioner in a vehicle operating in an electronic device is provided, and fig. 1 is a flowchart of a method for controlling an air conditioner in a vehicle according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the steps of:
step S10, acquiring current environment information of the vehicle in a starting state;
wherein the current environment information is used to represent the current cabin environment of the vehicle.
The start state of the vehicle may be understood as a state after ignition of the vehicle or power-up of the vehicle, including but not limited to a vehicle driving state and a vehicle stationary state. When a vehicle is in a driving state, an air conditioner in the vehicle needs to be controlled to meet the comfort of a riding object and provide a comfortable riding environment for the riding object. When the vehicle is in a traffic jam section, the vehicle may have a discontinuous static state, and in this state, a comfortable riding environment needs to be provided for a riding object.
Specifically, the current environmental information of the vehicle in the starting state is obtained through various vehicle sensors in the vehicle, wherein the various vehicle sensors include but are not limited to a sunlight sensor, an in-vehicle temperature sensor, an air blower and an evaporator, and the current environmental information includes but is not limited to sunlight radiation information of the vehicle, temperature information in a cabin of the vehicle, air volume information of an air conditioner and temperature information of the air conditioner. The current environment information is used for representing the current cabin environment of the vehicle, namely the thermal environment information in the current cabin of the vehicle, and can be understood as the current environment information is used for representing the temperature information in the current cabin of the vehicle.
Because the temperature information in the vehicle cabin can directly influence the riding experience of the riding object, namely riding comfort, when a comfortable riding environment is provided for the riding object, the current environment information of the vehicle needs to be considered, so that the comfort of different body parts of the riding object is more accurately determined, measures are taken in a targeted manner, and the comfort of the riding object is further improved.
Illustratively, the sunlight radiation information of the vehicle, the temperature information in the cabin of the vehicle, the air volume information of the air conditioner and the temperature information of the air conditioner in the starting state of the vehicle are obtained according to the sunlight sensor, the temperature sensor in the vehicle, the air blower and the evaporator, and the current environment in the cabin of the vehicle is represented through the sunlight radiation information of the vehicle, the temperature information in the cabin of the vehicle, the air volume information of the air conditioner and the temperature information of the air conditioner.
Step S11, determining somatosensory parameters of a plurality of body parts of a riding object of the vehicle under the current environment information;
because different body parts of a person can sense different temperatures, for example, the hands of the person can sense the temperature higher than the face of the person can sense the temperature, and when the hands sense the higher or lower temperature, the discomfort caused by the body correspondence is lower than that when the face senses the higher or lower temperature. Therefore, it is necessary to divide the body of a person into a plurality of body parts according to different body parts, and to comprehensively improve the comfort of the whole person by considering the comfort of each body part.
The plurality of body parts include, but are not limited to, the head, face, neck, left shoulder, right shoulder, forebreast, hindbreast, foreabdomen, hindabdomen, 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 a body part of a riding subject, the wind speed blowing towards the surface of the body part, and the radiation temperature of sunlight impinging on the surface of the body part. The somatosensory parameters can be understood as thermal environment information of different body parts, and comfortable feeling, namely comfort degree, of the different body parts to the current environment information in the cabin can be determined according to the somatosensory parameters.
Illustratively, somatosensory parameters of a head, a face, a neck, a left shoulder, a right shoulder, a chest, an abdomen, a belly, a left arm, a right arm, a left hand, a right hand, a left leg, a right leg, a left foot and a right foot of a riding object of the vehicle under the current environment information are respectively determined, so that the comfort degree of the seventeen body parts under the current cabin environment is determined.
Step S12, determining a target body part from a plurality of body parts based on the somatosensory parameters;
wherein, under the current environment information, the first comfort level perceived by the target body part is lower than the second comfort level perceived by the body part except the target body part in the plurality of body parts.
Step S12 may be understood as determining, according to the somatosensory parameters corresponding to each body part, a target body part with the lowest comfort level in the current cabin environment among the plurality of body parts. Since the comfort level of the target body part is the lowest, the target body part needs to be cooled or heated, so that the comfort level of the target body part is improved, and the comfort level of the whole human body of the riding object is improved.
Specifically, when the target body part is determined, the comfort level of each body part perceived in the current cabin environment is determined through the somatosensory parameters, and the lower the comfort level is, the worse the comfort feeling of the body part is. Thereby the size of the comfort level through comparing every health position determines the first comfort level that the comfort level is the lowest, and the health position that first comfort level corresponds is target health position, and the comfort level that the health position other than target health position perceived under current environmental information in a plurality of health positions is the second comfort level, and it can be understood that first comfort level is less than the second comfort level.
Exemplarily, the comfort level corresponding to each body part is determined according to the somatosensory parameters, the comfort levels corresponding to the body parts are sorted from large to small, the comfort level with the lowest comfort level is the first comfort level, and the body part corresponding to the first comfort level is the target body part needing targeted blowing. From this, can accurately determine the target body position that the comfort level is the lowest from a plurality of body positions according to body sensing parameter.
In addition, if the comfort level corresponding to the plurality of body parts is the same, the target body part can be determined according to the priority levels of the plurality of body parts. Specifically, the priorities of the seventeen body parts are sequentially reduced from top to bottom when the season outside the vehicle is spring and summer, and it can be understood that the priorities of the body parts are sequentially head, face, neck, left shoulder, right shoulder, chest, abdomen, back, left arm, right arm, left hand, right hand, left leg, right leg, left foot, and right foot from large to small when the season outside the vehicle is spring and summer. When the season outside the vehicle is autumn and winter time, the priority of the seventeen body parts is sequentially increased from top to bottom according to the position in the human body, and the priority of the body parts is understood to be that when the season outside the vehicle is autumn and winter time, the priority of the body parts is sequentially head, face, neck, left shoulder, right shoulder, forebreast, hindbreast, foreabdomen, hind abdomen, left arm, right arm, left hand, right hand, left leg, right leg, left foot and right foot from small to large. For example, when the season outside the vehicle is autumn and winter, the comfort levels of the left shoulder and the left leg are determined to be the same from the multiple body parts and the comfort levels corresponding to the multiple body parts are the lowest comfort levels through the somatosensory parameters, and then the priority of the left leg is determined to be greater than the priority of the left shoulder according to the priority ranking, so that the target body part is determined to be the left leg.
And S13, controlling an air outlet of an air conditioner of the vehicle to face the target body part.
Wherein the third comfort level that the wind gap is used for making target body part perception is higher than first comfort level.
It is understood that the air conditioner of the vehicle includes a plurality of vents each for outputting an air volume (i.e., blowing air) to lower or raise the ambient temperature in the vehicle compartment. Generally, different air ports correspond to different riding objects, and it can be understood that the ambient temperature around each riding object is adjusted by the output air volume of the corresponding air port.
For example, when the target body part is the head, the air outlet of the air conditioner corresponding to the riding object is rotated towards the head of the riding object, so that the air outlet of the air conditioner faces the target body part of the riding object, and the target body part is blown, thereby achieving the technical effect of cooling or heating the target body part, improving the overall comfort level of the human body of the riding object, and reducing the energy consumption of the air conditioner.
It can be understood that after the air outlet of the air conditioner faces the target body part, the comfort level sensed by the target body part can be changed, the third comfort level sensed by the target body part after the air outlet is adjusted is higher than the first comfort level sensed by the target body part before the air outlet is adjusted, namely the comfort level of the target body part is improved, and therefore the whole comfort level of a passenger is improved.
Illustratively, the direction of an air inlet of an air conditioner of the vehicle is controlled, so that the targeted body part is subjected to targeted cooling or heating operation, the comfort level of the targeted body part is improved, and the overall comfort level of the human body of the riding object is further improved.
Therefore, the air inlet of the air conditioner of the vehicle is controlled to face the target body part, so that the air conditioner of the vehicle can pointedly improve the comfort level of the local body part of the riding object, meanwhile, the intelligent degree of the air conditioner is improved, and the comfort level of the riding object of the vehicle is further improved.
Through the steps, by acquiring the current environment information of the vehicle in the starting state, wherein the current environment information is used for representing the current cabin environment of the vehicle, and because comfort degrees of different body parts of a riding object to the current cabin environment are different in feeling, somatosensory parameters of the body parts of the riding object of the vehicle under the current environment information are determined, namely, the comfort degrees corresponding to the different body parts under the current environment information are determined. The method comprises the steps of determining a target body part from a plurality of body parts based on somatosensory parameters, wherein under current environment information, a first comfort level perceived by the target body part is lower than a second comfort level perceived by a body part except the target body part in the plurality of body parts, and the target body part is the body part which is uncomfortable for a riding object under the current environment information. The air inlet of the air conditioner of the control vehicle faces towards the target body part, and the air inlet is used for enabling the third comfort level of the perception of the target body part to be higher than the first comfort level, so that the target body part is subjected to blowing operations such as cooling or heating and the like in a targeted mode, the comfort level of the target body part is improved, the comfort level of the whole body of a riding object is improved, and meanwhile the energy consumption of the air conditioner is reduced. The aim of enabling the air opening of the air conditioner in the vehicle to be capable of pertinently facing to the local body part of the riding object and blowing air to the local body part is achieved, the technical effects of improving the intelligent degree of the air conditioner, reducing the energy consumption of the air conditioner and improving the comfort of the riding object are achieved, and the technical problem of the intelligent degree of the air conditioner caused by the fact that the targeted blowing air cannot be achieved through the air opening of the air conditioner in the related technology is solved.
Alternatively, in step S10, acquiring the current environment information of the vehicle in the activated state may include performing the steps of:
and acquiring current environment information of the vehicle in a starting state through a vehicle sensor.
The vehicle sensor comprises a sunlight sensor, an in-vehicle temperature sensor, an air volume sensor and an evaporator temperature sensor, the sunlight sensor is used for acquiring sunlight radiation information of a vehicle in current environment information, the in-vehicle temperature sensor is used for acquiring temperature information in the cabin of the vehicle in the current environment information, the air volume sensor is used for acquiring air volume information of an air blower in the current environment information, and the evaporator temperature sensor is used for acquiring temperature information of an evaporator in the current environment information.
Specifically, the sunlight sensor senses the external sunlight irradiation amount of the vehicle in the current environment, measures the heat radiation intensity of sunlight, and obtains the sunlight radiation information of the vehicle in the current environment, so that accurate sunlight radiation information is provided for the current environment information of the vehicle in the starting state.
The in-vehicle temperature sensor obtains the cabin temperature information of the vehicle in the current environment by sensing the temperature in the vehicle cabin in the current environment, so that accurate cabin temperature information is provided for the current environment information of the vehicle in the starting state.
The air blower is used for sending air blown out by the air conditioner into the vehicle cabin, and the air quantity sensor obtains air quantity information of the air blower of the vehicle in the current environment by sensing the air quantity, so that accurate air quantity information of the air blower is provided for the current environment information of the vehicle in the starting state.

Therefore, the current environmental information of the vehicle in the starting state is acquired through the vehicle sensors of various different types, so that accurate sunlight radiation information, temperature information in a vehicle cabin, air volume information of an air conditioner and temperature information of the air conditioner are provided in the process of subsequently determining the somatosensory parameters of a plurality of body parts of a riding object of the vehicle under the current environmental information, namely, the accurate current environmental information is provided, and the accuracy of the somatosensory parameters is further ensured.
Alternatively, in step S11, determining somatosensory parameters of a plurality of body parts of a riding object of the vehicle under the current environment information may include performing the following steps:
and determining somatosensory parameters according to the current environment information and the target neural network model.
The target neural network model is obtained by training an initial neural network model based on an environmental information sample of a vehicle and a somatosensory parameter sample of a riding object, and the environmental information sample corresponds to the somatosensory parameter sample.
When the neural network model is trained, the initial neural network model is trained through an environmental information sample and a somatosensory parameter sample obtained through actual experiments or simulation, so that a high-precision target neural network model is obtained, and it can be understood that the environmental information sample corresponds to the somatosensory parameter sample. When the environmental information sample and the somatosensory parameter sample are obtained, the environmental information sample of the vehicle and the somatosensory parameter sample of the riding object can be determined according to the environmental information of the vehicle and the somatosensory parameter of the riding object under different working conditions. Specifically, different working conditions can be understood as different sunlight radiation information of the vehicle, temperature information in the cabin of the vehicle, air volume information of the air conditioner and temperature information of the air conditioner, and the somatosensory parameter samples are obtained through actual experiments or simulation under different working conditions.
By inputting the current environment information into the target neural network model, somatosensory parameters of a plurality of body parts are accurately output according to the target neural network model.
Therefore, the target neural network model is obtained through training, the current environment information is input into the target neural network model, the somatosensory parameters of the multiple body parts of the riding object under the current environment information are obtained, accurate somatosensory parameters of the multiple body parts can be provided for the subsequent process of determining the target body part from the multiple body parts based on the somatosensory parameters, and the accuracy of determining the target body part is further guaranteed.
Optionally, the somatosensory parameters include a temperature of a surface of the body part of the riding object, a wind speed blowing toward the surface of the body part, and a radiation temperature of sunlight irradiating the surface of the body part.
The somatosensory parameters are used for representing the comfortable state of the surface of the body part of the riding object, specifically, the somatosensory parameters corresponding to different body parts are different, and the comfortable state of the surface of different body parts can be determined according to the somatosensory parameters.
Alternatively, in step S12, determining a target body part from the plurality of body parts based on the somatosensory parameters may include performing the steps of:
determining comfort levels of a plurality of body parts based on the somatosensory parameters;
when determining the comfort levels of the plurality of body parts, the comfort levels of the plurality of body parts may be determined based on the somatosensory parameters and a comfort algorithm, which may be, for example, a Zhang comfort algorithm. Specifically, because the comfort levels corresponding to different body parts are different in calculation mode, the comfort level algorithm can determine the comfort levels of different body parts according to somatosensory parameters corresponding to different body parts.
Illustratively, the comfort level of each body part is determined according to the surface temperature of the body part of the riding object, the wind speed blowing to the surface of the body part and the radiation temperature of sunlight irradiating the surface of the body part, so that the accurate and basis comfort level is provided for determining the target body part by comparing the comfort levels of a plurality of body parts, and the accuracy of the determined target body part is further ensured.

the body part corresponding to the first comfort level is determined as a target body part.
The comfort levels of the multiple body parts are ranked from large to small, the lowest comfort level is the first comfort level, and the first comfort level corresponds to the target body part with the worst comfort level in the multiple body parts.
It can be understood that, since the comfort level is determined based on the somatosensory parameters of the multiple body parts, that is, the comfort level of the human body in the current environment can be represented, the comfort levels of the multiple body parts are compared, the body part with the minimum comfort level is the body part which is most uncomfortable for the riding object in the current environment, that is, the body part which needs to be subjected to comfort level adjustment, and thus the part is determined as the target body part. The air inlet of the air conditioner of the vehicle is controlled to provide accurate direction information in the process of moving towards, so that the intelligent degree of an air conditioner control system is improved, the comfort level of a target body part is further improved, and the comfort level of passengers in the current environment is improved.
Alternatively, in step S13, controlling the air outlet of the air conditioner of the vehicle toward the target body part may include performing the steps of:
identifying a target body part to obtain target position information;
determining a target rotation angle of a grill of the air conditioner corresponding to the target position information;
and controlling the air opening to face the target body part according to the target rotation angle of the grille.
Wherein the target position information is used for representing the position of the target body part in the current cabin environment.
The method comprises the steps of identifying a target body part from a plurality of body parts, obtaining the position of the target body part in a vehicle, namely a target information position, determining a target rotating angle of a grid of the air conditioner corresponding to target position information, controlling an air opening to face the target body part according to the target rotating angle of the grid, adjusting the rotating angle of the grid of the air conditioner according to the target information position, enabling the air opening of the air conditioner to face the target body part accurately, carrying out targeted cooling or heating operation on the target body part, and improving the intelligent degree of an air conditioner control system and the overall comfort of a riding object.
Specifically, the positions of the air outlets of the air conditioners corresponding to different vehicle types are different, that is, the rotation angle of the grille of the air conditioner needs to be determined according to the actual conditions of different vehicle types. It is understood that a certain angle range and a rotation manner may be set for the grill rotation of the air conditioner depending on the target body part. In an alternative embodiment, when the target body part is the position of the leg of the occupant, since the range of the position of the leg of the occupant is large, the grill of the air conditioner may be set to a rotation angle range between the ankle and the knee of the occupant in a mode of cyclic swing within the above-mentioned angle range, thereby satisfying different conditions of the target body part.
Therefore, the control method of the air conditioner in the vehicle provided by the embodiment of the invention can make the air outlet of the air conditioner blow to the local body part of the riding object in a targeted manner, and improves the human body local comfort of the riding object and the intelligent degree of the air conditioner.
