[0074] Optionally, the inner surface of the capacitor layer 104 is covered with a protective layer 107 , and the protective layer 107 is used to protect the capacitor layer 104 .

[0075] Those skilled in the art should understand that the above-mentioned terminal devices and servers are only examples, and other existing or future terminal devices or servers, if applicable to this application, should also be included in the scope of protection of this application and are included here by reference.

[0076] The embodiment of the present application provides a vehicle sunshade method, which can be applied to the above Figure 1 The implementation environment shown is Figure 2 As an example, the flowchart of a vehicle sunshade method provided by the embodiment of the present application is shown in FIG. Figure 1 The electronic device 105 in the embodiment is executed. Figure 2 As shown, the method includes the following steps 201 to 203.

[0077] In step 201, a first touch time and a first touch position sent by a capacitive sensor are received, where the first touch time is the time corresponding to the first touch operation on the capacitive layer, and the first touch position is the position corresponding to the first touch operation on the capacitive layer.

[0078] In an exemplary embodiment of the present application, the inner surface of a vehicle's sunroof is covered with an electrochromic film, the inner surface of which is covered with a capacitive layer. A capacitive sensor and electronic equipment are installed in the vehicle. The capacitive layer is connected to the capacitive sensor, which is in turn connected to the electronic equipment, which controls the transparency of the electrochromic film.

[0079] The transparency of the electrochromic film is a first transparency, which indicates that the electrochromic film is transparent. The first transparency is set based on experience or can be flexibly adjusted according to the implementation environment, and is not limited in the embodiments of this application. For example, the first transparency is 100. This means that the electrochromic film is completely transparent, and sunlight outside the vehicle can penetrate through the vehicle's sunroof and into the vehicle interior.

[0080] When the driver and passengers of the vehicle feel that the sunlight shining into the interior of the vehicle is dazzling and want to block the sunlight from entering the interior of the vehicle, the driver and passengers of the vehicle can touch the capacitor layer. When the driver and passengers of the vehicle touch the capacitor layer, since the driver and passengers of the vehicle are grounded, the capacitance of the touched position in the capacitor layer will change. Since the capacitor layer and the capacitor sensor are connected, the capacitor sensor can detect the change in capacitance of the touched position. The capacitor sensor records the first touch time corresponding to the first touch operation on the capacitor layer and the first touch position corresponding to the first touch operation on the capacitor layer, and sends the first touch time and first touch position to the electronic device, so that the electronic device receives the first touch time and first touch position sent by the capacitor sensor.

[0081] Optionally, the inner surface of the capacitor layer may be covered with a protective layer to protect the capacitor layer from damage. If the inner surface of the capacitor layer is covered with the protective layer, the capacitance of the touched location in the capacitor layer will also change if the driver or passenger touches the protective layer.

[0082] In step 202, a second touch time and a second touch position sent by the capacitive sensor are received, where the second touch time is the time corresponding to the second touch operation on the capacitive layer, and the second touch position is the position corresponding to the second touch operation on the capacitive layer.

[0083] In one possible implementation, when the driver or passenger touches the capacitive layer again, the capacitive sensor records the second touch time corresponding to the second touch operation on the capacitive layer and the second touch position corresponding to the second touch operation on the capacitive layer, and sends the second touch time and the second touch position to the electronic device, so that the electronic device receives the second touch time and the second touch position sent by the capacitive sensor.

[0084] In step 203, when the time interval between the second touch time and the first touch time is less than the first time threshold and the second touch position and the first touch position meet the position requirement, the transparency of the electrochromic film is adjusted to a second transparency, which is lower than the first transparency.

[0085] The first time threshold is set based on experience or flexibly adjusted according to the implementation environment, which is not limited in the embodiment of the present application.

[0086] Optionally, it is possible to first determine whether the time interval between the second touch time and the first touch time is less than the first time threshold, and if the time interval between the second touch time and the first touch time is less than the first time threshold, then determine whether the second touch position and the first touch position meet the position requirement. Alternatively, it is possible to first determine whether the second touch position and the first touch position meet the position requirement, and if it is determined that the second touch position and the first touch position meet the position requirement, then determine whether the time interval between the second touch time and the first touch time is less than the first time threshold. The embodiment of the present application does not limit the time sequence of determining whether the time interval between the second touch time and the first touch time is less than the first time threshold and determining whether the second touch position and the first touch position meet the position requirement.

[0087] In a possible implementation, the process of determining the time interval between the second touch time and the first touch time includes: subtracting the second touch time from the first touch time to obtain the time interval between the second touch time and the first touch time.

[0088] Exemplarily, the second touch time is 14:15:20 on June 11, 2025, and the first touch time is 14:15:15 on June 11, 2025, and the time interval between the second touch time and the first touch time is 5 seconds.

[0089] In a possible implementation, the embodiment of the present application provides the following two implementations to determine whether the second touch position and the first touch position meet the position requirements.

[0090] Implementation method 1: determining a first area according to a first touch position; and determining whether the second touch position and the first touch position meet position requirements according to the first area and a second touch position.

[0091] Optionally, the process of determining the first area based on the first touch location includes: determining a circle with the location information of the first touch location as the center and the target length as the radius, and defining the area covered by the circle as the first area. The target length is set based on experience or flexibly adjusted according to the implementation environment, and is not limited in this embodiment of the present application. For example, the target length is 3 centimeters.

[0092] In one possible implementation, the process of determining whether the second touch position and the first touch position meet the position requirements based on the first area and the second touch position includes: when the second touch position is within the first area, determining that the second touch position and the first touch position meet the position requirements; when the second touch position is outside the first area, determining that the second touch position and the first touch position do not meet the position requirements.

[0093] In this implementation, by determining whether the second touch position is located in the first area determined based on the first touch position, it is determined whether the second touch position and the first touch position meet the position requirements, so that the method of determining whether the second touch position and the first touch position meet the position requirements is more flexible and the accuracy of the determination result is higher.

[0094] Implementation method 2: determining the distance between the second touch position and the first touch position; and determining whether the second touch position and the first touch position meet position requirements based on the distance between the second touch position and the first touch position.

[0095] In a possible implementation, the process of determining the distance between the second touch position and the first touch position includes: determining the distance between the second touch position and the first touch position according to position information of the second touch position and position information of the first touch position.

[0096] Optionally, the distance between the second touch position and the first touch position is determined according to the following formula (1) based on the position information of the second touch position and the position information of the first touch position.

[0097]

[0098] In the above formula (1), L is the distance between the second touch position and the first touch position, (X2, Y2) is the position information of the second touch position, and (X1, Y1) is the position information of the first touch position.

[0099] In one possible implementation, after determining the distance between the second touch position and the first touch position, the process of determining whether the second touch position and the first touch position meet the position requirement based on the distance between the second touch position and the first touch position includes: if the distance is less than a distance threshold, determining that the second touch position and the first touch position meet the position requirement; if the distance is not less than the distance threshold, determining that the second touch position and the first touch position do not meet the position requirement.

[0100] The distance threshold is set based on experience or flexibly adjusted according to the implementation environment, which is not limited in the present embodiment. For example, the distance threshold is 3 centimeters.

[0101] In this implementation, by determining the distance between the second touch position and the first touch position, it is determined whether the second touch position and the first touch position meet the position requirements, so that the method of determining whether the second touch position and the first touch position meet the position requirements is more flexible and the accuracy of the determination result is higher.

[0102] It should be noted that any of the above implementation methods can be selected to determine whether the second touch position and the first touch position meet the position requirements, and the embodiments of the present application are not limited to this.

[0103] In a possible implementation, if the time interval between the second touch time and the first touch time is not less than the first time threshold, and / or the second touch position and the first touch position do not meet the position requirement, then subsequent steps do not need to be performed.

[0104] In one possible implementation, if the time interval between the second touch time and the first touch time is less than a first time threshold, and the second touch position and the first touch position meet position requirements, the transparency of the electrochromic film is adjusted to a second transparency, which is lower than the first transparency. This can reduce the amount of sunlight entering the vehicle interior, thereby achieving the purpose of sunshade.

[0105] Optionally, before adjusting the transparency of the electrochromic film to the second transparency, it is necessary to first obtain the second transparency. The second transparency can be a pre-set transparency or a transparency determined based on the current ambient temperature, which is not limited in this embodiment of the present application. In the case where the second transparency is a pre-set transparency, the second transparency can be set based on experience or flexibly adjusted according to the implementation environment, which is not limited in this embodiment of the present application. For example, the second transparency is 0.

[0106] In this implementation, the transparency of the electrochromic film is adjusted to the second transparency only when the time interval between the second touch time and the first touch time is less than the first time threshold and the second touch position and the first touch position meet the position requirements. This can not only accurately filter out erroneous operations caused by driving bumps, unintentional touch by drivers and passengers, and avoid incorrect adjustment of the transparency of the electrochromic film, but also conform to the natural operating habits of drivers and passengers of quick and continuous clicking, reduce learning costs, and improve the fluency and intuitiveness of the interactive experience.

[0107] In another possible implementation, the process of obtaining the second transparency includes: obtaining the current ambient temperature; and determining the second transparency according to the current ambient temperature.

[0108] In this implementation, the transparency of the electrochromic film is dynamically adjusted based on the current ambient temperature, so that the adjusted transparency of the electrochromic film conforms to the current ambient temperature, thereby improving the driving comfort of the driver and passengers.

[0109] Optionally, the process of obtaining the current ambient temperature includes: the vehicle includes a temperature sensor, the temperature sensor is used to obtain the current ambient temperature, and the temperature sensor is communicatively connected to the electronic device via a wired network or a wireless network. After obtaining the current ambient temperature, the temperature sensor transmits the current ambient temperature to the electronic device, so that the electronic device obtains the current ambient temperature.

[0110] Optionally, the process of determining the second transparency according to the current ambient temperature includes: using the transparency corresponding to the current ambient temperature as the second transparency; or determining the light intensity corresponding to the current ambient temperature and using the transparency corresponding to the light intensity as the second transparency.

[0111] In a possible implementation, the electronic device stores correspondences between various temperatures and transparencies. The electronic device determines the transparency corresponding to the current ambient temperature and uses the transparency corresponding to the current ambient temperature as the second transparency.

[0112] In a possible implementation, the light intensity corresponding to the current ambient temperature is determined according to the following formula (2).

[0113]

[0114] In the above formula (2), E is the light intensity corresponding to the current ambient temperature, A is the surface albedo, σ is the Stefan constant, t is the current ambient temperature, and τ is the atmospheric transmittance.

[0115] Among them, the value of Stefan constant is 5.67*10 -8 W / (m 2 ·K 4) (Watts per square meter Kelvin (Kelvin 4). The surface albedo varies depending on the surface. For example, grass has an albedo of 0.2, while snow has an albedo of 0.8. Atmospheric transmittance depends on the weather: clear weather has an albedo of 0.7, while cloudy weather has an albedo of 0.3.

[0116] For example, the current ambient temperature is 25°C (degrees Celsius), the ground is asphalt, the surface albedo is 0.1, the weather is clear, and the atmospheric transmittance is 0.7. The above formula (2) can be used to determine the light intensity: (Watts / square meter). That is, the light intensity corresponding to the current ambient temperature is 713 watts / square meter.

[0117] Optionally, the electronic device stores a correspondence between various light intensities and transparencies, and uses the transparency corresponding to the light intensity corresponding to the current ambient temperature as the second transparency.

[0118] In this implementation, two processes for determining the second transparency according to the current ambient temperature are provided, so that the determination method of the second transparency is more flexible.

[0119] In one possible implementation, after the transparency of the electrochromic film is adjusted to the second transparency, the driver and passenger can also touch the capacitive layer. After the capacitive sensor receives the third touch operation on the capacitive layer, it records the third touch time corresponding to the third touch operation on the capacitive layer, and sends the third touch time to the electronic device, so that the electronic device receives the third touch time sent by the capacitive sensor; when the time interval between the third touch time and the second touch time is less than the second time threshold, the third transparency is determined based on the second transparency, and the third transparency is different from the second transparency; the transparency of the electrochromic film is controlled to change from the second transparency to the third transparency according to the reference step; in the process of the transparency change of the electrochromic film, in response to receiving the touch information sent by the capacitive sensor, the fourth transparency is determined, and the fourth transparency is the transparency of the electrochromic film when the touch information is received; the transparency of the electrochromic film is adjusted to the fourth transparency.

[0120] The second time threshold is set based on experience or flexibly adjusted according to the implementation environment, and is not limited in the embodiments of the present application. The second time threshold may be the same as or different from the first time threshold, and is not limited in the embodiments of the present application. The reference step size is set based on experience or flexibly adjusted according to the implementation environment, and is not limited in the embodiments of the present application. For example, the reference step size is 10.

[0121] In one possible implementation, the process of determining the third transparency based on the second transparency includes: when the second transparency is the first value, determining the third transparency to be the second value, and the second value is greater than the first value; when the second transparency is not the first value, determining the third transparency to be the first value.

[0122] The first value and the second value are set based on experience, or are flexibly adjusted according to the implementation environment, and are not limited in this embodiment of the present application. For example, the first value is 0 and the second value is 100.

[0123] In one possible implementation, the process of controlling the transparency of the electrochromic film to change from the second transparency to the third transparency according to a reference step includes: when the second transparency is a first value, controlling the transparency of the electrochromic film to increase from the second transparency to the third transparency according to the reference step; when the second transparency is not the first value, controlling the transparency of the electrochromic film to decrease from the second transparency to the third transparency according to the reference step.

[0124] For example, when the second transparency is 0, the transparency of the electrochromic film is controlled to increase from 0 to 100 according to the reference step size.

[0125] For another example, when the second transparency is 50, the transparency of the electrochromic film is controlled to decrease from 50 to 0 according to the reference step size.

[0126] In one possible implementation, while the electrochromic film's transparency changes, the driver or passenger can control the film's transparency by touching the capacitive layer. When the driver or passenger touches the capacitive layer again, the capacitive sensor sends touch information to the electronic device. Upon receiving the touch information, the electronic device determines a fourth transparency level, which is the film's transparency at the time of the touch information, and then adjusts the film's transparency to the fourth level.

[0127] For example, when the touch information is received, the transparency of the electrochromic film is 30, the fourth transparency is determined to be 30, and then the transparency of the electrochromic film is adjusted to 30.

[0128] In this implementation, the electrochromic film's transparency changes from a second transparency to a third transparency in reference steps, allowing drivers and passengers to dynamically perceive the light transmittance of the vehicle's sunroof. By fixing the transparency of the electrochromic film through touch, drivers and passengers have control over the film, allowing the transparency to be quickly locked to their desired setting. This not only meets the driver's and passengers' needs for flexible intelligent adjustment, but also improves interaction efficiency and user experience.

[0129] In one possible implementation, after adjusting the transparency of the electrochromic film to the fourth transparency, the driver or passenger may further adjust the transparency of the electrochromic film to the first transparency to allow sunlight to penetrate into the interior of the vehicle through the vehicle windows.

[0130] Optionally, the fifth touch time and the fifth touch position sent by the capacitive sensor are received, where the fifth touch time is the time corresponding to the receipt of the fifth touch operation on the capacitive layer, and the fifth touch position is the position corresponding to the receipt of the fifth touch operation on the capacitive layer; the sixth touch time and the sixth touch position sent by the capacitive sensor are received, where the sixth touch time is the time corresponding to the receipt of the sixth touch operation on the capacitive layer, and the sixth touch position is the position corresponding to the receipt of the sixth touch operation on the capacitive layer; when the time interval between the sixth touch time and the fifth touch time is less than the first time threshold, and the sixth touch position and the fifth touch position meet the position requirements, the transparency of the electrochromic film is adjusted to the first transparency.

[0131] The process of determining the time interval between the sixth touch time and the fifth touch time is similar to the process of determining the time interval between the second touch time and the first touch time, and is not further described in detail in this embodiment of the present application. The process of determining whether the sixth touch position and the fifth touch position meet the position requirements is similar to the process of determining whether the second touch position and the first touch position meet the position requirements, and is not further described in detail in this embodiment of the present application.

[0132] The above method covers the inner surface of the vehicle's sunroof with an electrochromic film and covers the inner surface of the electrochromic film with a capacitor layer. In this way, the transparency of the electrochromic film can be adjusted by touching the capacitor layer. Since the transparency of the electrochromic film after adjustment is lower than the transparency before adjustment, the sunlight that passes through can be reduced, thereby achieving the purpose of sunshade for the vehicle.

[0133] Moreover, there is no need to install new controls inside the vehicle to achieve vehicle sunshade, so there are fewer controls inside the vehicle, which makes the vehicle sunshade method more flexible.

[0134] In addition, the transparency of the electrochromic film is adjusted only when the capacitive layer is touched twice, the time interval between the two touches is less than the first time threshold, and the positions of the two touches meet the position requirements. This can avoid the situation where the transparency of the electrochromic film is adjusted due to accidental touch.

[0135] Figure 3 This is a flow chart of a vehicle sunshade method provided by an embodiment of the present application. Figure 3 As shown, the method includes the following steps 301 to 315.

[0144] Step 306: Whether the second touch position and the first touch position meet the position requirement.

[0145] If the second touch position and the first touch position meet the position requirement, step 307 is executed; if the second touch position and the first touch position do not meet the position requirement, the process ends.

[0146] Step 307: Adjust the transparency of the electrochromic film to a second transparency.

[0147] Step 308: Whether a third touch operation on the capacitive layer is received.

[0148] If the third touch operation on the capacitive layer is received, step 309 is executed; if the third touch operation on the capacitive layer is not received, the process ends.

[0149] Step 309: Acquire the third touch time of the third touch operation.

[0150] Step 310: Whether the time interval between the third touch time and the second touch time is less than a second time threshold.

[0151] If the time interval between the third touch time and the second touch time is less than the second time threshold, step 311 is executed; if the time interval between the third touch time and the second touch time is not less than the second time threshold, the process ends.

[0152] Step 311: Determine a third transparency according to the second transparency.

[0153] Step 312: Control the transparency of the electrochromic film to change from the second transparency to the third transparency according to the reference step size.

[0154] Step 313: Whether a fourth touch operation on the capacitive layer is received.

[0155] If the fourth touch operation on the capacitive layer is received, step 314 is executed; if the fourth touch operation on the capacitive layer is not received, the process ends.

[0156] Step 314 : Determine a fourth transparency, where the fourth transparency is the transparency of the electrochromic film when a fourth touch operation on the capacitive layer is received.

[0157] Step 315: Adjust the transparency of the electrochromic film to a fourth transparency.

Specifically, when the ambient light intensity is high, the display brightness of the display screen 505 is increased; when the ambient light intensity is low, the display brightness of the display screen 505 is decreased. In another embodiment, the processor 501 can also dynamically adjust the shooting parameters of the camera assembly 506 based on the ambient light intensity detected by the optical sensor 513.

The proximity sensor 514 is used to detect the distance between the user and the front of the terminal device 500. In one embodiment, when the proximity sensor 514 detects that the distance between the user and the front of the terminal device 500 is gradually decreasing, the processor 501 controls the display screen 505 to switch from the screen-on state to the screen-off state. When the proximity sensor 514 detects that the distance between the user and the front of the terminal device 500 is gradually increasing, the processor 501 controls the display screen 505 to switch from the screen-off state to the screen-on state.
