[0042] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0043] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0044] In the summer, sunlight shining through car windows can cause glare and temperature rise inside the car. This is mainly due to the transmission and absorption characteristics of car windows. When sunlight enters the car, part of the light is absorbed by the car windows, while the other part is transmitted into the car. The light that enters the car through the glass can increase the heat in the cabin, causing the temperature inside the car to rise. In addition, some car windows may have high reflective properties, reflecting part of the sunlight, making the external light more glaring.

[0045] The light transmittance of the vehicle glass 10 refers to the ability of light to pass through the glass, that is, the degree of transmission and penetration of light on the glass. The light transmittance of the vehicle glass 10 is very important for the driver and passengers because it directly affects the clarity and comfort of the field of vision.

[0046] like Figure 2 As shown, the present invention provides a vehicle cabin environment adjustment method for a vehicle-mounted terminal, comprising the following steps:

[0047] S1. Obtaining occupant biological information, ambient light information, and ambient temperature information recognized by the vehicle-mounted sensor 20.

[0048] The above scheme requires obtaining the occupant's biological information in advance, where the occupant's biological information includes eye information, body temperature, respiratory rate and heart rate. The eye information mainly includes the direction of sight, eye position, etc., and may also include pupil dilation and shrinkage information, frowning information, etc. With the development of technology, the occupant's biological information that can be collected in the car may include information such as blood pressure that cannot be collected currently.

[0049] The occupants in this application mainly refer to the driver in the driving position. If it is necessary to collect the biometric information of occupants in other positions, vehicle-mounted sensors 20 can be set in other positions. The following schemes in this application all take the driver as an example.

[0050] The vehicle-mounted sensor 20 includes a camera disposed on the main driving side and facing the driver's face, which can also be used as a face recognition camera.

[0051] The on-board sensor 20 recognizes eye information in the following manner: The technology of using a camera to recognize the direction of a person's gaze is generally referred to as "gaze tracking" or "eye tracking" technology. Gaze tracking technology uses special algorithms and models in the camera to detect and track the position and movement of a person's eyes. Typically, these algorithms use image processing and machine learning methods to analyze the characteristics of the human eye, such as the pupil, the corner of the eye, etc., and determine the position and direction of the eye. Once the position and direction of the eye are determined, the camera can calculate the direction of the person's gaze, that is, the position or object the person is looking at.

[0052] The vehicle-mounted sensor 20 recognizes body temperature by using infrared thermal imaging technology, which calculates the surface temperature of a target object by detecting infrared radiation emitted by the target object.

[0053] The onboard sensor 20 identifies the respiratory rate in the following way: the camera can capture the movement of the chest or abdomen of a person, which is caused by the breathing movement. Through computer vision algorithms, these movements can be analyzed and identified to calculate the respiratory rate.

[0054] The on-board sensor 20 identifies the heart rate in the following way: the driver's heart rate can be identified through facial color change analysis or heart rate variability analysis. Facial color change analysis: Changes in heart rate can cause slight color changes in the facial skin. For example, the speed and amount of blood flow will change with the heartbeat. By taking a video or image of a person's face with a camera, image processing and computer vision algorithms can be used to extract color change information in the facial area. This information can be used to calculate the heart rate. Heart rate variability analysis: Heart rate variability refers to the irregularity and variability of the heartbeat intervals. It is a physiological indicator of the heart rate response to the regulation of the autonomic nervous system. By recording slight movements of a person's face or skin with a camera, different image processing and computer vision techniques can be applied to extract the characteristics of these heart rate variability. These characteristics can be used to calculate the heart rate.

[0055] The above-mentioned ambient lighting information includes ambient lighting angle and ambient lighting intensity.

[0056] The vehicle-mounted sensor 20 includes a sunlight sensor for detecting the ambient light angle and a light sensor for detecting the ambient light intensity, which are arranged on the vehicle. The sunlight sensor can identify the position of the sun at 360 degrees horizontally and vertically, and can identify cloudy days, overcast days, semi-cloudy days, sunny days and daytime at night. The light sensor is a device for measuring the light intensity in the environment. It uses a photosensitive element (such as a photodiode or a photoresistor) to convert light into an electrical signal, and determines the light level by measuring the intensity of the signal.

[0057] The above steps also include the following steps:

[0058] S11 , acquiring the occupant's biological information and the ambient temperature information recognized by the vehicle-mounted sensor 20 .

[0059] The vehicle-mounted sensor 20 includes an outside thermometer and an inside thermometer for measuring the outside temperature and the inside temperature of the vehicle, respectively.

[0060] S12, judging whether cabin environment adjustment is required according to the occupant biological information and / or ambient temperature information;

[0061] For example, when an occupant's heart rate accelerates, breathing rate increases, body temperature rises, pupils shrink, etc., the cabin environment needs to be adjusted, such as lowering the air-conditioning temperature and lowering the glass transmittance. When the outside ambient temperature is high, the air-conditioning temperature and glass transmittance can be lowered. When the outside ambient temperature is low, the glass transmittance at the non-driver's line of sight can be increased to improve the light transmittance of the entire vehicle, so as to increase the temperature inside the vehicle through natural light to reduce energy consumption.

[0062] S13: When it is determined that the cabin environment needs to be adjusted, the ambient light information recognized by the vehicle-mounted sensor 20 is obtained.

[0063] In the above scheme, the subsequent information acquisition and execution steps are only entered when the system determines that the cabin environment needs to be adjusted, so as to reduce the computing power requirements.

[0064] S2. Sending an adjustment instruction to an adjustment device and / or an air conditioner according to the occupant biological information, the ambient temperature information, and the ambient lighting information to adjust the dark area position and the dark area transmittance of the adjustable glass and / or air conditioning parameters.

[0065] The above adjustment method has the following embodiments:

[0066] Embodiment 1: sending an adjustment instruction to the adjustment device according to the eye information in the occupant's biological information, so as to adjust the position of the dark area to avoid the area of ​​the adjustable glass that is fixed by the line of sight in the eye information.

[0067] When using the windshield, it is necessary to ensure that it has sufficient light transmittance to ensure that the driver can clearly see the road and the surrounding environment during the day and at night. The area of ​​the adjustable glass that the line of sight is looking at in the eye information is generally the middle or lower part of the main driver's side of the windshield. Avoiding the dark area at this position can avoid the interference of the dark area on the line of sight. As the driver turns his head left and right to observe the environment through other glasses, the color depth of the glass position where the driver's line of sight is directly looking can be correspondingly reduced. When the driver actually uses the vehicle, the driver does not need to look directly at the sun, but only needs to observe the road surface and the left and right positions. The glass position corresponding to the direct sunlight on the driver's eyes (that is, the glass position where the line connecting the sun and the driver's eyes passes is generally located at the upper part of the glass) is different from the glass position that the driver's eyes are looking at (that is, the glass position where the line connecting the road surface and the driver's eyes passes is generally located in the middle and lower part of the glass). The sunlight shining into the lower part of the left and right windows generally does not directly hit the driver's eyes but directly hits the skin of the driver and passengers. When the driver needs to observe the rearview mirror or the surrounding environment, the color depth can be reduced at the corresponding position to facilitate the driver's observation. At the same time, the driver's observation position is not where the sunlight directly hits the eyes, and even if the color is reduced, it will not affect the driver's eyes. In this way, in most cases, the sunlight can be prevented from directly hitting the skin and eyes of the passengers in the car while ensuring the driver's field of vision when needed. Among them, embodiment 1 can coexist with embodiments 2, 3, and 4, and embodiment 1 has a higher priority than embodiments 2, 3, and 4.

[0068] Embodiment 2: sending an adjustment instruction to the adjustment device according to the ambient light angle in the ambient light information, so as to adjust the dark area to be the area of ​​the adjustable glass illuminated by the ambient light.

[0069] The area of ​​the adjustable glass illuminated by ambient light refers to the area where sunlight can directly shine into the vehicle's glass through the corresponding glass. For example, when the sun sets and the vehicle moves from south to north, the sunlight can directly shine into the vehicle from the glass of the two left windows and the skylight glass. At this time, the transmittance of the two left windows and the skylight glass can be reduced to avoid rapid temperature increase and impact on skin health caused by excessive sunlight entering the car.

[0070] Embodiment three: obtaining the corresponding glass area through which light directly hits the eye according to the eye information in the occupant's biological information and the ambient light intensity in the ambient light information; sending an adjustment instruction to the adjustment device according to the corresponding glass position to adjust the corresponding glass area to the dark area.

[0071] The corresponding glass area through which light directly hits the eyes refers to the area where sunlight can directly hit the eye position through a certain glass. At this time, the camera can recognize that the human eye has an obvious light spot, or calculate in real time based on the eye position, the vehicle glass 10 position and the light angle which position of the glass the sunlight at that location is passing through, which is generally the upper part of the windshield and the upper side of the main driving window glass, that is, the glass position corresponding to the main driving sun visor. The light transmittance of the upper part of the windshield or the upper part of the main driving window glass can be reduced to avoid safety hazards caused by direct sunlight to the human eyes.

[0072] Embodiment 4: Sending adjustment instructions to the adjustment device and / or air conditioner based on the body temperature, breathing rate, heart rate in the occupant's biological information, the ambient temperature information, and the ambient light intensity in the ambient light information to adjust the transmittance of the dark area and / or air conditioning parameters.

[0073] In the above scheme, when the body temperature rises, the breathing rate increases, the heart rate increases, the external environment temperature is high, and the ambient light intensity is high, the glass transmittance of the corresponding area of ​​the vehicle can be reduced; when the external environment temperature is low and the ambient light intensity is low, the glass transmittance of the corresponding area of ​​the vehicle can be increased. For example, the glass transmittance of the corresponding area of ​​the vehicle can be reduced at noon on a sunny day in summer, and increased at night.

[0074] The present invention also provides a vehicle cabin environment adjustment device, comprising:

[0075] An information acquisition module, used to acquire the occupant's biological information, ambient light information, and ambient temperature information recognized by the vehicle-mounted sensor 20;

[0076] A control module sends an adjustment instruction to an adjustment device and / or an air conditioner according to the occupant biological information, the ambient temperature information, and the ambient light information, so as to adjust the dark area position and the dark area transmittance of the adjustable glass and / or the air conditioning parameters.

[0077] like Figure 1 As shown, the present invention also provides a vehicle cabin environment conditioning system, including an air conditioner, a vehicle glass 10, an inductance unit 40, a vehicle cabin environment conditioning device, and a vehicle-mounted sensor 20, wherein the inductance unit 40 is arranged on the vehicle glass and is used to change the color depth of the vehicle glass by changing the current; the vehicle cabin environment conditioning device is such as the above-mentioned vehicle cabin environment conditioning device; the vehicle-mounted sensor 20 is used to obtain occupant biological information, ambient light information, and ambient temperature information.

[0078] Also included is a vehicle machine 30 .

[0079] The vehicle glass 10 comprises:

[0080] Windshield: The windshield is the glass at the front of the vehicle, which provides the most important field of view during driving. The windshield usually needs to have a high light transmittance to ensure that the driver can get a clear view of the front during both daytime and nighttime.

[0081] Side window glass: Side window glass usually uses transparent glass to provide good light transmittance and allow the driver and passengers to observe the environment around the vehicle.

[0082] Rear windshield: The rear window glass usually needs to provide good light transmittance to ensure that the driver has a clear view to the rear.

[0083] Skylight glass: Located on the top of the vehicle. Some new energy vehicles do not have skylight sunshades, so the amount of light transmittance is generally larger.

[0084] The inductor units can be distributed in a certain area or as a whole on a single piece of glass.

[0085] The adjustable glass in this application refers to inductive glass, which is a special glass material that can change its transparency and reflective properties by applying an electric field. It can achieve reversible color changes from a transparent state to a light or dark state under the action of an electric field. Inductive glass is usually composed of an electrolyte layer and an electrochromic dye layer sandwiched between two thin transparent electrodes. When an electric field is applied, the ions in the electrolyte will move between the two electrodes, causing the electrochromic dye molecules to undergo a redox reaction, thereby causing the color of the glass to change. By changing the applied voltage and current, the transparency and color of the inductive glass can be controlled.

[0086] In summary, the present invention proposes a vehicle cabin environment adjustment method, device and system. In the above scheme, it is necessary to obtain the occupant's biological information in advance. According to the occupant's biological information, it can be determined whether the window glass color needs to be adjusted and the part that needs to adjust the color. Then, the light transmittance of the whole vehicle is changed by setting the adjustable glass to adjust the color depth, and the air-conditioning temperature and air volume and other parameters are adjusted synchronously. The glass and air-conditioning changes are intelligently matched to achieve an economical and energy-saving state. At the same time, the situation of direct sunlight into the human eyes is reduced and the impact of sunlight on skin health is reduced.
