[0002] With economic development and rising income levels, the number of family cars is increasing year by year, and people's demands for the convenience and comfort of car use are also constantly increasing.

[0003] During driving, ambient light is constantly changing. When driving at night, if other vehicles suddenly appear in the direction of oncoming traffic, the interior light will suddenly increase, and the high brightness will irritate the eyes and affect driving safety. Alternatively, when there is a significant change in ambient light (such as from a tunnel to sunlight, or from sunlight to a tunnel), the interior brightness will change abruptly. Strong sunlight will not only accelerate the aging of the car's interior but also irritate the eyes and affect driving safety.

[0004] In existing technology, a dark film is usually applied to the car windows and windshield to reduce the intensity of light entering the car. However, when the sunlight is weak in the morning and evening, the dark film will make the interior of the car darker and will also affect the driver's observation of road conditions.

[0029] Figure 2 This is a schematic diagram of an in-vehicle light intensity control device provided in an embodiment of the present invention. Detailed Implementation

[0030] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] Please refer to Figure 1 This embodiment proposes a method for controlling the light intensity inside a vehicle, including: determining the target light intensity inside the vehicle; determining the direction of light irradiation outside the vehicle and the current light intensity inside the vehicle; determining the adjustment parameters corresponding to each shading element of the vehicle based on the direction of light irradiation outside the vehicle, the current light intensity inside the vehicle, and the target light intensity inside the vehicle; wherein, the shading element is a component used to adjust the light intensity inside the vehicle; and adjusting the shading element according to the adjustment parameters corresponding to the shading element to adjust the light intensity inside the vehicle to the target light intensity inside the vehicle.

[0033] Specifically, in this embodiment of the invention, after the vehicle is started, the target light intensity inside the vehicle is first determined. During vehicle operation, the current light intensity inside the vehicle is detected in real time using an in-vehicle current light intensity determination unit. If the difference between the current light intensity inside the vehicle and the target light intensity is greater than a set difference, it indicates a deviation between the current light intensity and the target light intensity, requiring adjustment of the light-shielding element to adjust the current light intensity inside the vehicle to the target light intensity. An external light illumination direction determination unit is also installed inside the vehicle. Both the in-vehicle current light intensity determination unit and the external light illumination direction determination unit are light intensity sensors. The external light illumination direction determination unit includes multiple light intensity sensors, each positioned differently and with different tilt angles or orientations. These sensors can be used to detect the light intensity at different locations and angles inside the vehicle. Based on the light intensity detected by the multiple light intensity sensors at different locations, the external light illumination direction can be determined. Then, based on the direction of external light illumination, the current light intensity inside the vehicle, and the target light intensity inside the vehicle, the adjustment parameters corresponding to each light-shielding element of the vehicle are determined. The light-shielding elements are then adjusted according to their corresponding adjustment parameters to bring the light intensity inside the vehicle up to the target light intensity. In this embodiment, at least three light intensity sensors are provided to detect the direction of external light illumination, respectively located at the front, left rear, and right rear of the vehicle. The unit for determining the current light intensity inside the vehicle is located in the middle of the vehicle.

[0034] Based on the above-mentioned technical means, the light intensity inside the vehicle can be adaptively adjusted to maintain the light intensity inside the vehicle at a stable target light intensity, thereby improving driving safety. Furthermore, the adjustment parameters corresponding to each light-shielding element of the vehicle can be determined according to the direction of external light, the current light intensity inside the vehicle, and the target light intensity inside the vehicle, making the dimming smoother and more precise. This makes the adjusted light intensity inside the vehicle more in line with the needs of the users inside the vehicle, thereby improving the comfort of the users inside the vehicle.

[0035] In this embodiment, determining the adjustment parameters corresponding to each light-shielding element of the vehicle based on the direction of external light illumination, the current light intensity inside the vehicle, and the target light intensity inside the vehicle includes: determining the adjustment weights of multiple light-shielding elements of the vehicle based on the direction of external light illumination; determining the overall adjustment ratio of the light-shielding elements based on the current light intensity inside the vehicle and the target light intensity inside the vehicle; and determining the adjustment parameters corresponding to each light-shielding element based on the overall adjustment ratio and the adjustment weight corresponding to each light-shielding element.

[0036] In this embodiment, determining the adjustment weights of multiple shading elements of the vehicle based on the direction of external light illumination includes: determining the adjustment weights of the shading elements based on the relationship between the setting position of the shading elements and the direction of external light illumination.

[0037] Specifically, in this embodiment of the invention, because external light has an illumination angle, the light-shielding elements closer to the direction of external light illumination are significantly affected by it. If the adjustment parameters of the light-shielding elements closer to the direction of external light illumination are adjusted for all the light-shielding elements in the vehicle, other light-shielding elements will be over-adjusted. If the light-shielding elements are adjusted according to the overall light intensity inside the vehicle, the light-shielding elements closer to the direction of external light illumination cannot be adjusted to the applied adjustment parameters, and the light intensity near these light-shielding elements will be greater than or less than the target light intensity inside the vehicle. Therefore, in this embodiment, each light-shielding element can be adjusted individually according to the direction of external light illumination to ensure accurate light-shielding element conditions. First, the adjustment weight of each light-shielding element is determined according to the direction of external light illumination. Then, the overall adjustment ratio of the light-shielding elements is determined according to the current light intensity inside the vehicle and the target light intensity inside the vehicle. Multiplying the overall adjustment ratio by the adjustment weight corresponding to each light-shielding element yields the adjustment parameters corresponding to each light-shielding element.

[0038] Specifically, the adjustment weight of the sunshade element can be determined based on the relationship between the setting position of the sunshade element and the direction of external light illumination. In one possible implementation, the vehicle is equipped with light-blocking elements on the windshield, driver's side window, passenger side window, driver's side rear window, passenger side rear window, and rear windshield. External light shines from the driver's side window onto the passenger side rear window at a 45-degree angle to the horizontal plane. The light enters the vehicle from the driver's side window, windshield, and driver's side rear window. Since the driver's seat is closest to the driver's side window and windshield, the driver's side window has the highest adjustment weight. The passenger side receives a large area of ​​illumination from the windshield, so its adjustment weight is second highest. The seat behind the driver receives light from the driver's side rear window, but the window area is small and there is no other light entering from the front, so the driver's side rear window has the next highest adjustment weight. Therefore, the adjustment weights, from highest to lowest, are: driver's side window, driver's side rear window, windshield, passenger side window, passenger side rear window, and rear windshield. If sunlight shines from the driver's side window onto the passenger side window, and the angle between the sunlight and the horizontal plane is 30 degrees, the driver's seat and the rear seat behind the driver receive sunlight from the same direction. However, the driver's seat is closer to the windshield, so the adjustment weight of the driver's side window is the highest, followed by the rear window. Since the passenger side is not directly illuminated, the windshield adjustment weight is the third highest. Therefore, the corresponding adjustment weights, from highest to lowest, are: driver's side window, driver's side rear window, windshield, passenger side window, passenger side rear window, and rear windshield.

[0039] Based on the aforementioned technical means, the adjustment parameters corresponding to each light-shielding element of the vehicle can be determined according to the direction of light illuminating the vehicle from outside, the current light intensity inside the vehicle, and the target light intensity inside the vehicle. This makes the dimming smoother and more precise, so that the adjusted light intensity inside the vehicle better meets the needs of the users inside the vehicle, thereby improving the comfort of the users inside the vehicle.

[0040] In this embodiment, determining the target light intensity inside the vehicle includes: determining the light intensity inside the vehicle when the vehicle is started as the target light intensity inside the vehicle.

[0041] In this embodiment, the method further includes: after the vehicle is started, if a user-triggered light-shielding element adjustment command is detected, the in-vehicle light intensity adjusted based on the user-triggered light-shielding element adjustment command is determined as the in-vehicle target light intensity.

[0042] Specifically, in this embodiment of the invention, if the driver does not adjust the shading element when the vehicle starts, the interior light intensity at the time of vehicle startup can be defaulted to the target interior light intensity. If the driver adjusts the shading element during driving, the interior light intensity after the shading element is adjusted is determined as the target interior light intensity.

[0043] Based on the aforementioned technical means, the target light intensity inside the vehicle can be adjusted in a timely manner according to the user's adjustment operation, accurately determining the target light intensity inside the vehicle. This allows for timely adjustment of the corresponding light-shielding elements based on the target light intensity inside the vehicle, making the adjusted light intensity inside the vehicle more in line with the needs of the users and improving their comfort.

[0044] In this embodiment, the light-blocking elements include: a vehicle window, a sun visor, a vehicle window curtain, and a vehicle window light transmittance adjustment element.

[0045] Specifically, in this embodiment of the invention, the light-blocking element includes one or more of the following: a vehicle window, a sun visor, a vehicle window curtain, and a vehicle window light transmittance adjustment element.

[0046] Based on the aforementioned technical means, the light intensity inside the vehicle can be adjusted in multiple ways, with flexible and varied adjustment methods that can be selected according to the user's usage habits, thereby improving the user experience.

[0047] In this embodiment, determining the direction of external light illumination includes: detecting the light intensity at different locations inside the vehicle; and determining the direction of external light illumination based on the magnitude of the light intensity at different locations inside the vehicle.

[0048] Specifically, in this embodiment of the invention, at least three light intensity sensors are provided to detect the direction of light illuminating the vehicle from outside. These sensors are respectively located at the front of the vehicle, the left rear of the vehicle, and the right rear of the vehicle. Each light intensity sensor has a different tilt angle or orientation, which can detect the light intensity at different locations and in different directions of illumination. Then, the light intensity at different locations is input into the light intensity prediction model to determine the direction of light illuminating the vehicle from outside.

[0049] Based on the aforementioned technical means, the direction of external light can be accurately determined according to the light intensity at different locations inside the vehicle. This allows for subsequent adjustment of the weight of different light-shielding elements based on the direction of external light, resulting in more precise light adjustment that better meets the needs of vehicle users and improves the user experience.
