[0001] The present application relates to the technical field of vehicle-mounted lighting control, and in particular to a method for controlling an ambient light, a vehicle computer and a vehicle. Background Art
[0002] With the improvement of living standards, driving is not only a commuting activity, but also a pursuit of comfort and fun. In order to increase driving pleasure, vehicles are usually equipped with ambient lights to illuminate the passenger space and interior with changing colors. However, in existing cars, the color change of ambient lights is independent and cannot interact with the content displayed on the car computer. It is very monotonous and inconsistent with the content displayed on the car computer. Summary of the invention
[0003] In view of this, the present application provides a method for controlling an ambient light, a vehicle computer, and a vehicle.
[0004] Specifically, the present application is implemented through the following technical solutions:
[0005] In a first aspect of the present application, a method for controlling an ambient light is provided. The ambient light is installed in an automobile, and the automobile also includes a vehicle computer. The method includes: determining a main color of the ambient light according to the display content of the vehicle computer; if the color spectrum of the ambient light includes the main color, controlling the ambient light to display the main color; if the color spectrum of the ambient light does not include the main color, controlling the ambient light to display an adjacent color of the main color.
[0006] According to a second aspect of the present application, a vehicle computer is provided, which includes: a memory storing a program; and a processor, which is used to implement the steps of the method provided in the first aspect of the present application when executing the program.
[0007] A third aspect of the present application provides a car, which includes the car computer and ambient light provided in the second aspect of the present application.
[0008] Through the above scheme, the present application has at least the following beneficial effects:
[0009] The vehicle computer establishes direct communication with the ambient light, determines a main color based on the screen display content, and controls the color of the ambient light to be the same or similar to it. Therefore, when playing videos or navigating, the color of the ambient light will change as the vehicle display content changes. Since the colors are the same or similar, the color of the ambient light and the color of the screen are relatively unified, forming a coordinated color atmosphere in the car and enhancing driving pleasure.

[0021] With the improvement of living standards, driving is no longer just a monotonous act of commuting, but has become a kind of enjoyment and experience. People have begun to have higher expectations for the driving experience, and the pursuit of comfort and fun has become an important demand in the driving process. In order to increase driving pleasure, automakers have begun to install ambient lights in vehicles, which illuminate the passenger space and interior of the car by changing colors, creating a more pleasant atmosphere for drivers and passengers.
[0022] However, the functions of the car ambient lights on the market are relatively simple and independent. These ambient lights can only perform simple color changes and cannot interact with the content displayed on the car computer, resulting in limited experience. Drivers and passengers may feel that the color effects they experience in the car are irrelevant to the content displayed on the car computer or even conflict with each other, lacking overall coordination, which to some extent affects the pleasure of the driving experience.
[0023] With the continuous advancement of technology, the future car ambient lights will not be limited to simple color changes, but will be able to interact intelligently with the vehicle system to bring a more pleasant and personalized driving experience to drivers and passengers, making the driving process no longer just a means to reach the destination, but also an experience of enjoyment and spiritual relaxation.
[0024] For this purpose, refer to Figure 1 The present application proposes a method for controlling an ambient light, wherein the ambient light is installed in a car, and the car also includes a car computer. The method may include:
[0025] S101, determining the main color of the ambient light according to the display content of the vehicle computer;
[0026] S102, if the color spectrum of the ambient light includes the main color, controlling the ambient light to display the main color;
[0027] S103: If the color spectrum of the ambient light does not include the main color, control the ambient light to display a color adjacent to the main color.
[0028] Through the above solution, the color of the vehicle's ambient light is unified with the color of the display content of the vehicle computer, forming a coordinated color atmosphere in the car and enhancing driving pleasure.
[0029] There is no specific requirement for the installation location of the ambient light. The ambient light located inside the car can implement the solution provided in this application.
[0030] It can be understood that the main color refers to the color that accounts for the largest proportion in the displayed content. For example, if 60% blue, 30% red and 10% green are displayed, blue can be set as the main color.
[0031] Specifically, the main body color can be obtained through an external device (such as a camera) or a vehicle computer interface, and the acquisition method is not specifically limited in this application.
[0032] Accordingly, the present application also provides a method for obtaining the main body color. An embodiment can refer to Figure 2 , the main color can be obtained according to the modules in the figure. As shown in the figure, the display module 201 is used to display the video screen, and obtain the RGB value of each pixel from the display driver and pass it to the RGB value analysis module 202. The RGB value analysis module 202 is used to analyze according to the RGB value of each pixel, such as counting the number of pixels corresponding to each RGB value. Taking the m×n resolution display screen as an example, the display screen is regarded as an overall area, which is divided into m×n pixels. The RGB value of each pixel is extracted one by one, and the number of pixels with the same RGB value is counted. Finally, the RGB value with the largest proportion (the number of pixels with the same RGB value / the total number of pixels) is calculated. This RGB value is used as the RGB value of the theme color, that is, the theme is determined. The domain control module 203 is responsible for receiving the RGB value of the main color and routing the data to the atmosphere light control module 204. The atmosphere light control module 204 is used to control the atmosphere light 205 to display the same or similar color according to the RGB value of the main color.
[0033] The brightness of the ambient light is associated with sound or audio. On the basis of controlling the color according to the picture content of the car computer, the brightness of the ambient light can also be determined according to the audio information output by the car computer. The brightness is positively correlated with the volume of the audio information.
[0034] For example, when the decibel value is 0, the brightness level of the ambient light is 0, when the decibel value is 1, the brightness level of the ambient light is 1, and so on, when the decibel value is greater than or equal to 100, the brightness level of the ambient light is always 100. In a preferred embodiment of the present application, it is assumed that the brightness of the ambient light is divided into 101 levels, namely 0, 1, 2, ..., 100, corresponding to the ambient light off, brightness 1%, brightness 2%, ..., brightness 100%, respectively.
[0035] In a preferred embodiment of the present application, the atmosphere light is simultaneously associated with the display content and related audio information. When the user is watching a video, the color of the atmosphere light changes according to the change of the main color of the video. At the same time, the brightness of the atmosphere light changes according to the change of the decibel value of the audio information.
[0036] On the basis of the above solution, the automobile may further include a vehicle state monitoring module, which is used to monitor the motion state of the automobile. If the vehicle state monitoring module detects that the vehicle is in a stationary state, the method may further include:
[0037] The fatigue of the car occupants is monitored, and based on the fatigue of the occupants, the weight of the main color of the ambient light is determined according to the display content of the car computer, or the weight of the brightness of the ambient light is determined according to the audio information output by the car computer.
[0038] It is understandable that in one embodiment of the present application, fatigue monitoring can be performed by a camera, and the camera can be any camera that can detect the state of a living body, such as a camera in a DMS (Driver Monitoring System). The target occupant can be a driver or a passenger, and the installation position of the camera can also be different when the seating position is different.
[0039] To understand the solution, please refer to Figure 3a as well as Figure 3b ,Detecting the posture of the occupants is one of the means to determine whether they are tired. The degree of fatigue can be reflected by the fatigue evaluation index, Figure 3a When the driver is driving normally, the body is in an upright position. Figure 3b The driver is already tired, his posture is irregular, and he tends to bend over. Figure 3a , Figure 3b In a similar way, different fatigue evaluation indicators can be obtained to control the frequency of changes in the color or brightness of the ambient light.
[0040] In addition to posture, fatigue evaluation indicators can also be obtained through facial detection, such as eye opening angle, blinking frequency, facial shaking, etc. Other ways to obtain fatigue evaluation indicators are not described in detail in this application, and the specific implementation methods can refer to the corresponding technical solutions.
[0041] In actual scenarios, fatigue usually occurs in two situations. In one situation, the driver may become tired while driving. When the fatigue evaluation index becomes higher, the flashing frequency or the corresponding control frequency can be controlled to become faster to remind the driver to drive safely.
[0042] In another case, that is, when the car is stationary, the passengers in the car may stop to rest. At this time, controlling the frequency of brightness change according to the fatigue evaluation index may include: the larger the fatigue evaluation index, the lower the frequency of brightness change; at the same time, controlling the maximum value of brightness according to the fatigue evaluation index may include: the larger the fatigue evaluation index, the smaller the maximum value of brightness control.
[0043] Therefore, in one embodiment, the higher the occupant's fatigue level is, the lower the weight is.
[0044] In addition to controlling the color and brightness of the ambient light, in one embodiment, the power of the audio output of the vehicle computer can also be controlled according to the fatigue of the occupant; that is: the higher the fatigue of the occupant, the lower the power of the audio output of the vehicle computer; the lower the fatigue of the occupant, the higher the power of the audio output of the vehicle computer.
[0045] It is understandable that the output power is positively correlated with the volume of the sound, and the specific corresponding curves vary depending on the power amplifier, speaker, etc., and this application will not go into details one by one.
[0046] During long driving, the driver may need to rest due to fatigue to ensure driving safety. At this time, you can choose to stop and rest for a while in a service area or a safe place. You may take a short rest in the car when waiting for others or need personal space.
[0047] Through the above scheme, when parking for a rest, when controlling the changes of the ambient light through the vehicle computer display content, it is also possible to make appropriate adjustments according to the fatigue level of the occupants to avoid sudden changes in the ambient light caused by sudden changes in the display content, avoid disturbing the occupants, so as to assist the occupants to fall asleep and improve the user experience.
[0048] In the present application, the automobile may further include a vehicle state monitoring module, which is used to monitor the motion state of the automobile; if the vehicle state monitoring module detects that the automobile is in motion, the method further includes:
[0049] Obtain the vehicle position fed back by the navigation mode or real-time positioning mode of the vehicle computer;
[0050] monitoring the color of traffic lights when the car is within the intersection based on the vehicle's position;
[0051] Control the ambient light to warn according to the color of the traffic light;
[0052] Or, when it is determined based on the vehicle position that the car is outside the intersection, the distance between the car and the car in front is monitored, and the ambient light is controlled to issue a warning based on the distance between the car and the car in front.
[0053] Specifically, in one embodiment, the method of controlling the atmosphere light to give a warning may be to control the color of the atmosphere light to change to a warning color such as red or yellow, or to increase the brightness of the atmosphere light.
[0054] In the above embodiments, solutions are provided for improving the riding experience and driving safety in various scenarios such as when the car is stationary, driving in an intersection, and driving outside an intersection. Further, reference may be made to the contents recorded in the following embodiments to understand the present application.
[0055] In another embodiment, in a preferred embodiment of the present application, the ambient light control system includes a vehicle state monitoring module. When the vehicle state monitoring module detects that the vehicle is in a driving state, the vehicle will control the visual sensor to be in an open state, and the visual sensor can face the direction of the vehicle's movement. The method may also include:
[0056] Obtain the color of traffic lights through visual sensors;
[0057] The ambient light is controlled to display a warning color according to the color of the traffic light; when controlling the ambient light, the color of the traffic light has a higher priority than the display content of the vehicle computer.
[0058] It can be understood that in the above scheme, the visual sensor can be a camera, a color sensor, etc. The color of the acquired traffic light can be transmitted to the atmosphere light control module through other hardware, or it can be displayed in the display content of the vehicle computer, and then the scheme of detecting the color of the display content in the above scheme is used to enable the atmosphere light control module to perceive the color that needs to be controlled for the atmosphere light display.
[0059] When the visual sensor senses the color of the traffic light and the ambient light of the car computer is changing according to the display content of the car computer, the car computer should give priority to the color of the traffic light as a reference to control the ambient light. For example, when the car computer plays a video, it will control the ambient light to change color and flash according to the video display content. If you enter a traffic intersection at this time and the sensor detects the color of the traffic light, the color of the traffic light will be given priority to remind the driver to improve driving safety.
[0060] Based on the priority of the above-mentioned visual sensors, when the vehicle computer controls the ambient light to emit different colors of light, it can control the ambient light of all colors, or it can control the ambient light of some colors (such as Figure 4 When the car passes a traffic light, the car computer controls some colors of ambient lights to illuminate, such as Figure 4 If the ambient light on the middle right glows red (due to drawing limitations, dark red is used in the figure), it can be considered that the right turn signal light is red and right turn is prohibited.
[0061] Since you usually follow a fixed route specified by navigation when driving, you can also control the color of all ambient lights to indicate whether the next intersection is passable according to the navigation.
[0062] When controlling the light emission, the color of the atmosphere light can be controlled to be the same as or similar to the color of the traffic light, and the brightness can also be controlled to achieve the effect of flashing reminder.
[0063] It is understandable that the warning color of any solution in the present application can be any preset color such as red, yellow, etc.
[0064] In one embodiment, the vehicle may further include a distance sensor, the distance sensor facing the direction of the vehicle, and the method further includes:
[0065] Obtain the distance between the car and the vehicle in front through the distance sensor;
[0066] The ambient light is controlled to display a warning color according to the distance between the car and the car in front; when controlling the ambient light, the priority of the distance between the car and the car in front is higher than the priority of the display content of the car computer.
[0067] The ambient light is controlled to display a warning color according to the distance between the car and the car in front, which can effectively warn of danger in real time. The distance between vehicles has priority in controlling the ambient light and should take precedence over the car computer display content and traffic lights to prioritize the driving safety of people in the car.
[0068] Through the above solution, appropriate reminders can be given when the distance is not suitable for continuing to pass or it is difficult to stop in time. Since the ambient light is usually turned on at night and it is difficult to judge the distance when passing at night, controlling the ambient light as a reminder is more suitable for night driving and can improve driving safety.
[0069] Based on the same idea, the displayed content may also be navigation information, the navigation information including the distance between the vehicle and the intersection, and the method further includes:
[0070] The ambient light is controlled to display a warning color according to the distance between the vehicle and the intersection.
[0071] Navigation information is directly displayed on the car's computer display, making it easier to obtain and identify. It also avoids the use of other hardware and reduces usage costs.
[0072] In this application, navigation information can be considered as navigation information in the vehicle computer, or as navigation information of devices such as mobile phones. When other devices such as mobile phones are used for navigation or to display other content, they can also be regarded as a type of vehicle computer.
[0073] Based on any of the above embodiments, Figure 5 , the method may further include:
[0074] S601, obtaining the identity information of the current driver;
[0075] S602, retrieving a preset value according to the identity information;
[0076] S603: Adjust the frequency of change of the color or brightness of the ambient light to adapt to a preset value.
[0077] Since different people have different sensitivities to light, and different people may drive the same car, through the above solution, different people can store different preset values. When playing the same content, people who prefer cheerfulness can use a preset value with a sensitive response, while people who prefer quietness can use a preset value with a slow response. This method of controlling the atmosphere light can be applied to more types of car owners and meet diverse usage needs.
[0078] At the same time, by delegating adjustment authority to users through this preset value method, users can also experience more control over the vehicle and satisfy their psychological needs.
[0079] Accordingly, reference Figure 6 The present application further provides a vehicle computer 70, which includes:
[0080] A memory 701, wherein the memory 701 stores a program;
[0081] And a processor 702, which is used to implement the steps of the method in any of the above embodiments when executing the program.
[0082] refer to Figure 7 The present application also provides a car 80 , which includes a car machine 70 and an ambient light 205 .
