[0002] With the development of new automotive technologies, the ambient light in the car has become more and more, such as the extensive use of automotive atmosphere lights. As a decorative lamp, it is mainly used to make the car more gorgeous at night, set off the atmosphere, and create a more comfortable interior mood. With the maturity of atmosphere light technology and the reduction of costs, atmosphere lights are more and more widely used in car interiors. They are popular with the public and gradually enter the ranks of mass cars from exclusive features of high-end cars. At the same time, the number of atmosphere lights in the car is increasing, and the color of the atmosphere lights has also changed from monochrome light to RGB color adjustable; the brightness and color of the atmosphere lights in the car have become brighter and more colorful.

[0003] While the continuous development of personalized ambient lighting is gaining popularity, many people have also reported that the application of ambient lighting causes drivers and passengers to be easily dazzled, visually fatigued, and the glass imaging blocks the field of vision.

[0009] If the vehicle is in a driving state, the current interior ambient light illumination is obtained, and whether a night scene has been entered is determined according to the interior ambient light illumination; if the night scene has not been entered, the atmosphere light is displayed normally;

[0010] If entering a night scene, the ambient light illumination is generated according to the ambient light illumination inside the car, and it is determined whether the saturated color of the ambient light illumination is a low-saturated color. If so, the low-saturated color is directly output to the ambient light for display; if not, the saturated color of the ambient light illumination is adjusted to the low-saturated color and the low-saturated color is output to the ambient light for display.

[0011] Furthermore, in the step of adjusting the saturated color of the ambient light illumination to the low-saturated color, the formula for calculating the low-saturated color is:

[0013] Wherein, the ambient light coefficient = the ambient light illumination inside the vehicle / night scene calibration value.

[0014] Furthermore, the vehicle is provided with a fixed saturated color coordinate value corresponding to different illuminations of the ambient light, and the low-saturated color output to the ambient light is the fixed saturated color coordinate value corresponding to the illumination of the ambient light.

[0015] Furthermore, the vehicle is provided with a fixed ambient light brightness corresponding to different ambient light illuminations, and when the low-saturation color is output to the ambient light for display, the fixed ambient light brightness corresponding to the ambient light illumination is simultaneously output to the ambient light for display.

[0016] Furthermore, the vehicle is provided with a fixed ambient light brightness corresponding to different ranges of in-vehicle ambient light illumination. When the low-saturation color is output to the ambient light for display, the fixed ambient light brightness corresponding to the in-vehicle ambient light illumination is simultaneously output to the ambient light for display.

[0030] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] See also Figure 1 The present invention discloses a method for controlling a vehicle atmosphere light, comprising the following steps:

[0032] Get the on status of the ambient light;

[0033] If the ambient light is on, the current vehicle running state is obtained; if the vehicle is not in a running state, the ambient light is displayed normally;

[0034] If the vehicle is in a driving state, the current interior ambient light illumination is obtained, and whether a night scene has been entered is determined according to the interior ambient light illumination; if the night scene has not been entered, the atmosphere light is displayed normally;

[0035] If entering a night scene, the ambient light illumination is generated according to the ambient light illumination inside the car, and it is determined whether the saturated color of the ambient light illumination is a low-saturated color. If so, the low-saturated color is directly output to the ambient light for display; if not, the saturated color of the ambient light illumination is adjusted to the low-saturated color and the low-saturated color is output to the ambient light for display.

[0036] The vehicle running state includes the vehicle speed. In this embodiment, whether the vehicle is in the running state is determined by whether the vehicle speed reaches a preset speed of 5 km / h. When the vehicle speed is higher than or equal to 5 km / h, the vehicle is considered to be in the driving state; when the vehicle speed is lower than 5 km / h, the vehicle is considered to be in the non-driving state.

[0037] In other embodiments, the standard for determining whether the vehicle is in operation may also be set to a vehicle speed of 1km / h, 2km / h, etc., or as long as the speed is greater than 0km / h, the vehicle is considered to be in operation, without any particular limitation.

[0038] In this embodiment, first, the obtained in-vehicle ambient light illumination is converted into the atmosphere light illumination; then, the corresponding saturation level is obtained according to the atmosphere light illumination; finally, according to the corresponding saturation level, the saturated color and brightness of the atmosphere light are controlled to be output.

[0039] When it is determined that the vehicle is in a daytime scene, the ambient light does not need to be adjusted. When it is determined that the vehicle enters a night scene, the ambient light needs to adjust the saturated color and brightness of the ambient light output according to the ambient light illumination inside the vehicle.

[0040] The corresponding relationship between the in-vehicle ambient light illumination, the ambient light illumination, and the ambient light saturation level is as follows:

[0041]

[0042] In this embodiment, when it is determined that the vehicle enters a night scene, that is, when the interior ambient light illuminance is ≤1000 lux, the interior ambient light illuminance is set to a first illuminance level, a second illuminance level, and a third illuminance level. The first illuminance level is: 500 lux < interior ambient light illuminance ≤1000 lux, the second illuminance level is: 100 lux < interior ambient light illuminance ≤500 lux, and the third illuminance level is: interior ambient light illuminance ≤100 lux.

[0043] When the interior ambient light illuminance is within the first illuminance level range, the ambient light illuminance output is 700 lux; when the interior ambient light illuminance is within the second illuminance level range, the ambient light illuminance output is 400 lux; when the interior ambient light illuminance is within the first illuminance level range, the ambient light illuminance output is 100 lux.

[0044] Furthermore, when the illumination of the ambient light is 700 lux, the saturated color output of the ambient light is A-level saturated color; when the illumination of the ambient light is 400 lux, the saturated color output of the ambient light is B-level saturated color; when the illumination of the ambient light is 100 lux, the saturated color output of the ambient light is C-level saturated color. In this embodiment, the preset A-level saturated color is a high-saturated color, the B-level saturated color is a medium-saturated color, and the C-level saturated color is a low-saturated color.

[0045] Among them, saturation is the purity of color. The higher the purity, the brighter the performance; the lower the purity, the duller the performance. In other words, the higher the saturation, the more "aggressive" the picture is, and the more it can attract people's attention. However, too high saturation sometimes makes people feel uncomfortable, because over-saturated colors sometimes make the picture sticky, or lose the details of the picture. The lower the saturation, the more "peaceful" the picture is, and the more quiet and comfortable it gives people a visual experience. However, too low saturation sometimes makes the picture feel opaque or gray.

[0046] That is, taking red as an example, the purity of red in grade A saturated color is higher than that in grade B saturated color, and the purity of red in grade B saturated color is higher than that in grade C saturated color. Therefore, the higher the purity, the more obvious the visual impact on people, and the human eye is more likely to get tired if it captures the color with higher purity for a long time.

[0047] The relationship between saturation and color coordinate value (RGB value): When the proportion of the minimum value in the color coordinate value to the maximum value is larger, the saturation of the picture is lower. That is: saturation (S) = RGB (maximum color component value - minimum color component value) / maximum color component value * 100%. The higher the S value, the higher the saturation, and the lower the S value, the lower the saturation. Among them, the saturation of pure color can be reduced by adding other colors or increasing the gray value.

[0048] In this embodiment, in a night scene, when the vehicle determines that the ambient light output is a grade A saturated color or a grade B saturated color, the saturated color of the ambient light illumination is adjusted to the low saturated color and the low saturated color is output to the ambient light for display; when the vehicle determines that the ambient light output is a grade C saturated color, the low saturated color is directly output to the ambient light for display.

[0049] More specifically, when the vehicle determines that the saturated color level output by the ambient light is A-level saturated color or B-level saturated color, in the step of adjusting the saturated color of the ambient light illumination to the low-saturated color, the formula for calculating the low-saturated color is:

[0050] The coordinate value of the low saturation color = (the coordinate value of the saturation color of the ambient light illumination - 128) * ambient light coefficient + 128,

[0051] Wherein, the ambient light coefficient = the ambient light illumination inside the vehicle / night scene calibration value.

[0052] It should be noted that, according to common knowledge, when the interior ambient light illuminance is ≥7000 lux, it is defined as a daytime scene; when 7000 lux> the interior ambient light illuminance is ≥1000 lux, it can be defined as entering night. In this embodiment, the interior ambient light illuminance = 1000 lux is defined as entering night scene, that is, the night scene calibration value = 1000 lux.

[0053] The calculation principle of the saturated color coordinate value parameter output by the ambient light is: the lowest saturation of all colors is pure gray, and the color coordinate values ​​of pure gray are 128, 128, 128. The difference between the current coordinate and the color coordinate of pure gray is calculated, and then the difference is multiplied by the ambient light coefficient, and then 128 is added to the result.

[0054] First, when the ambient light outputs a non-low-saturation color, the difference between the ambient light color coordinate value of the current color and the minimum saturation is calculated respectively, and multiplied by the current ambient light coefficient respectively. The ambient light coefficient is equal to the ratio of the current in-car ambient light illumination to the night scene calibration value. The night scene calibration value defines the in-car ambient light illumination when entering the night scene. After the calculation is completed, it is added to the minimum saturation respectively to calculate the saturated color coordinate value of the ambient light illumination corresponding to the in-car ambient light illumination, and then the ambient light outputs the corresponding low-saturation color coordinate value.

[0055] In this embodiment, the night scene calibration value is 1000 lux, and the coordinate value of the low saturation color is calculated according to the interior ambient light illumination = (the coordinate value of the saturated color of the ambient light illumination - 128) * the interior ambient light illumination / 1000 + 128.

[0056] In more detail, R, G, and B represent red, green, and blue, respectively. In this embodiment, taking the pure red atmosphere light as an example, the color coordinate value of red is (255, 0, 0), and its saturation (S) = (255-0) / 255*100% = 1. Among them, 0≤S≤1, the higher the S value, the higher the saturation, and the lower the S value, the lower the saturation.

[0057] In this embodiment, taking the illumination of the interior ambient light of 500 lux as an example, when the illumination of the interior ambient light is 500 lux, according to the above correspondence, the illumination of the atmosphere light is 400 lux, and the atmosphere light outputs a saturated color of grade B. Among them, the saturated color of grade B is a non-low saturated color, and at this time it needs to be adjusted to the low saturated color according to the above calculation formula, and the adjustment result is the color coordinate value of the low saturated color = (191.5, 64, 64), and the corresponding saturation (S) = (191.5-64) / 191.5*100% = 0.665, at this time the saturation is reduced, and the atmosphere light outputs the corresponding low saturated color.

[0058] In addition, the color coordinate value of green is (0, 255, 0); the color coordinate value of blue is (0, 0, 255).

[0059] In this embodiment, the upper and lower limits of the first illumination level, the second illumination level and the third illumination level are set to 1000 lux, 500 lux and 100 lux respectively, and in other embodiments, they can also be set to other values. In this embodiment, the vehicle interior ambient light illumination = 1000 lux is defined as the night scene calibration value.

[0060] In other embodiments, the vehicle interior ambient light illuminance=2500 lux may be defined as the night scene calibration value, and the corresponding relationship between the vehicle interior ambient light illuminance-the ambient light illuminance-the ambient light saturation level is as follows:

[0061]

[0062]

[0063] Among them, the first illumination level is: 1400 lux < vehicle interior ambient light illumination ≤ 2500 lux, the second illumination level is: 900 lux < vehicle interior ambient light illumination ≤ 1400 lux, and the third illumination level is: vehicle interior ambient light illumination ≤ 900 lux.

[0064] When the interior ambient light illuminance is within the first illuminance level range, the ambient light illuminance output is 1500 lux; when the interior ambient light illuminance is within the second illuminance level range, the ambient light illuminance output is 1000 lux; when the interior ambient light illuminance is within the first illuminance level range, the ambient light illuminance output is 500 lux.

[0065] Furthermore, when the illumination of the ambient light is 1500 lux, the saturated color output of the ambient light is grade A; when the illumination of the ambient light is 1000 lux, the saturated color output of the ambient light is grade B; when the illumination of the ambient light is 500 lux, the saturated color output of the ambient light is grade C. In this embodiment, the preset grade A saturated color is a high saturated color, the grade B saturated color is a medium saturated color, and the grade C saturated color is a low saturated color.

[0066] The 1000lux, 500lux and 100lux, and even 2500lux, 1400lux and 900lux listed in the present invention are only certain cases of this embodiment. In other embodiments, the setting of the in-vehicle ambient light illumination may also be other values ​​to meet the purpose of the present invention, and no special limitation is made here.

[0067] In another embodiment, the saturated color parameter output by the ambient light can also be assigned manually. The vehicle is provided with a fixed saturated color coordinate value corresponding to different ambient light illuminations, and the low saturated color output to the ambient light is the fixed saturated color coordinate value corresponding to the ambient light illumination.

[0068] The relationship between the fixed saturated color coordinate value output by the preset atmosphere lamp in this embodiment and the illumination of the interior ambient light and the illumination of the atmosphere lamp is as follows:

[0069]

[0070]

[0071] Furthermore, in this embodiment, when it is determined that the vehicle enters a night scene, the vehicle is provided with a fixed ambient light brightness corresponding to different ambient light illuminations, and when the low-saturation color is output to the ambient light for display, the fixed ambient light brightness corresponding to the ambient light illumination is simultaneously output to the ambient light for display. The relationship between the preset ambient light brightness, the ambient light illumination in the vehicle, and the ambient light illumination in this embodiment is as follows:

[0072]

[0073] In more detail, when the interior ambient light illumination is within the first illumination level range, the ambient light illumination output is 700 lux; when the interior ambient light illumination is within the second illumination level range, the ambient light illumination output is 400 lux; when the interior ambient light illumination is within the first illumination level range, the ambient light illumination output is 100 lux.

[0074] Furthermore, when the illumination of the ambient light is 700 lux, the brightness output of the ambient light is level I brightness; when the illumination of the ambient light is 400 lux, the brightness output of the ambient light is level II brightness; when the illumination of the ambient light is 100 lux, the brightness output of the ambient light is level III brightness. In this embodiment, level I brightness is preset as high brightness, level II brightness is preset as medium brightness, and level III brightness is preset as low brightness.

[0075] More specifically, when the vehicle determines that the brightness level output by the ambient light is level I brightness or level II brightness, it is automatically adjusted to level III brightness; when the vehicle determines that the brightness level output by the ambient light is level III brightness, no adjustment is required.

[0076] In this embodiment, the definitions of level I brightness, level II brightness, and level III brightness are defined according to the present invention. In other embodiments, different levels are defined according to the corresponding illumination of the ambient light, which is not particularly limited here.

[0077] In another embodiment, the vehicle is provided with a fixed ambient light brightness corresponding to different ranges of in-vehicle ambient light illumination. When the low-saturation color is output to the ambient light for display, the fixed ambient light brightness corresponding to the in-vehicle ambient light illumination is simultaneously output to the ambient light for display.

[0078] Among them, when the interior ambient light illuminance is less than 1000 lux, that is, when entering a night scene, the fixed ambient light brightness of the ambient light can also be adjusted according to the interior ambient light illuminance. The relationship between the preset ambient light brightness and the interior ambient light illuminance is as shown in the following table:

[0079]

[0080] Alternatively, in other embodiments, the in-vehicle ambient light illumination may also be set to one level for every 100 lux, and the ambient light may be set to the same number of levels of brightness accordingly.

[0081] The above can be set according to the requirements of the present invention to achieve the present invention, and is not particularly limited here.

[0082] See also Figure 2 , the control process of the atmosphere light is as follows:

[0083] Turning on the atmosphere light;

[0084] Determine the driving state of the vehicle. When the vehicle speed is <5km / h, it is defined as the vehicle is not in driving state, and the ambient light is normally displayed. When the vehicle speed is ≥5km / h, it is determined that the vehicle is in driving state and the execution continues;

[0085] Determine the vehicle environment state, when the interior environment light illumination > 1000 lux, the atmosphere light is normally displayed, when the interior environment light illumination ≤ 1000 lux, continue to execute;

[0093] The control module is used to output or adjust the saturated color and brightness of the atmosphere light according to the result of the judgment module.

[0094] Among them, the atmosphere light, the detection module, the judgment module, the information collection module and the information processing module are connected to the control module, and the information collection module is connected to the information processing module.

[0095] See also Figure 4 Furthermore, the information collection module includes a vehicle speed sensor and an in-vehicle sunlight sensor, the vehicle speed sensor obtains the running speed of the vehicle, and the in-vehicle sunlight sensor obtains the ambient light intensity in the vehicle.
