Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to a lighting control method, a vehicle, and a readable storage medium. Background Technology

[0002] As smart cars and mobile office technologies become increasingly integrated, in-vehicle spaces are expanding from a single driving scenario to more diverse and multifunctional scenarios (such as office and living spaces). Taking the office scenario as an example, users in the rear seats can conduct video conferences, process documents, and perform other work while driving. However, the in-vehicle environmental control system has not yet fully adapted to this new demand. For instance, traditional in-vehicle reading lights still require manual activation via physical buttons or touchscreen menus. When users are concentrating on their work, this operation method may distract them, affecting work efficiency and user experience. Summary of the Invention

[0003] This application provides a lighting control method, a vehicle, and a readable storage medium, which eliminates the need for users to turn the vehicle's interior ceiling lights on or off via physical buttons or touchscreen menus, thus saving users the trouble of operation and effectively achieving efficient control of the vehicle's interior ceiling lights.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] In a first aspect, this application provides a lighting control method applied to a vehicle, the vehicle including multiple dome lights, the method comprising:

[0006] When it is detected that the interior of the vehicle is in a dark environment, and the user is using a first object with the user's head facing the first object, at least one of the plurality of dome lights is turned on, and the first object is within the illumination range of the at least one dome light.

[0007] Based on the lighting control method provided in this application, when the interior environment is dark, the user is using a first object (such as a paper document) and their head is continuously facing the first object, the first dome light in the corresponding area is automatically turned on. This eliminates the need for the user to manually operate physical buttons or touch screen menus, thus improving work efficiency. Furthermore, the first dome light in the corresponding position is only automatically turned on when all three conditions—dark environment, user using the first object, and the user's head facing the object—are met simultaneously. This accurately eliminates invalid scenarios, such as accidental light activation when the user is holding documents but not reading them. It effectively identifies the user's actual needs, reduces unnecessary lighting interference, ensures efficient matching of energy and function, and optimizes the user experience.

[0008] Furthermore, based on the above implementation method, at least one first overhead light corresponding to the first object can be precisely illuminated according to the user's actual application needs. In this way, when the user is engaged in activities such as reading inside the vehicle, their posture will no longer be restricted by the fixed position of the overhead light. This significantly improves the user's lighting experience in the vehicle cabin environment, creating a more comfortable, convenient, and personalized lighting environment.

[0009] In one possible implementation of the first aspect, the first object is a paper document, and the detection that the vehicle interior is in a dark environment, the user using the first object, and the user's head facing the first object, includes:

[0010] The system detects that the vehicle interior is in a dark environment, the user's hand is holding the unfolded paper document, and the user's head is facing the paper document.

[0011] In one possible implementation of the first aspect, the first object is an electronic device, and the detection that the vehicle interior is in a dark environment, the user using the first object, and the user's head facing the first object, includes:

[0012] The system detects that the vehicle interior is in a dark environment, the user's hand is holding the electronic device with its screen on, and the user's head is facing the electronic device.

[0013] It should be understood that an electronic device can be a device with a display screen, meaning that the electronic device has a display function. For example, electronic devices can be mobile phones, e-book readers, wristbands, smartwatches, personal digital assistants, tablets, in-vehicle computers, laptops, smart screens, super mobile personal computers, wearable devices, and so on.

[0014] In one possible implementation of the first aspect, the method further includes:

[0015] If the difference between the screen brightness of the electronic device and the illumination brightness of the at least one first top light is greater than or equal to a first threshold, the illumination brightness of the at least one first top light is adjusted according to the screen brightness.

[0016] Based on the above possible implementation methods, by balancing the screen brightness of the electronic device with the illumination brightness of at least one first overhead light, eye discomfort caused by using electronic devices in dark environments can be reduced, thereby alleviating visual burden, protecting eye health, and further improving the user experience.

[0017] In one possible implementation of the first aspect, the first object is a microphone, and the detection that the vehicle interior is in a dark environment, the user using the first object, and the user's head facing the first object, includes:

[0018] The system detects that the vehicle interior is in a dark environment, the user's hand is holding the microphone and the user's head is facing the microphone.

[0019] It should be understood that a sound pickup device can be a device that only has sound pickup functionality, such as a microphone, walkie-talkie, etc. A sound pickup device can also be a device that has both sound pickup and display functionality. Examples include mobile phones, personal digital assistants, tablets, in-vehicle computers, laptops, smart screens, super mobile personal computers, wearable devices, and other electronic devices. Of course, a sound pickup device can also be other devices oriented towards future technologies. This application does not impose any limitations on the specific type of sound pickup device.

[0020] In one example, a user using a microphone may also include the user holding the microphone in a microphone-collecting state with their hand. That is, if the vehicle interior is detected to be in a dark environment, and the user uses the first object with their head facing the first object, it may also include: detecting that the vehicle interior is in a dark environment, the user holding the microphone in a microphone-collecting state with their hand and the user facing the microphone.

[0021] Compared to the previous example where the user held the microphone in their hand, in this example, the user is holding a microphone that is already in microphone mode. It's easy to understand that a microphone in microphone mode can directly capture the user's voice signal. That is, not only does the user need to hold the microphone, but the microphone must also be actively picking up sound. This allows for more accurate identification of the user using the microphone, avoiding the waste of power caused by misidentifying the user's use due to moving the microphone around.

[0022] In one possible implementation of the first aspect, the pickup device includes a first pickup device and a second pickup device, and the method further includes:

[0023] Based on the switching of duet roles in the lyrics of the currently playing song, the second top light corresponding to the first microphone and / or the third top light corresponding to the second microphone are turned on among the plurality of top lights. The first microphone is within the illumination range of the second top light, and the second microphone is within the illumination range of the third top light.

[0024] In one possible implementation of the first aspect, the first object is a mirror, and the detection that the vehicle interior is in a dark environment, the user using the first object with the user's head facing the first object, includes:

[0025] The system detects that the interior of the vehicle is in a dark environment, so the user unfolds the mirror and the user's head is facing the mirror.

[0026] In one possible implementation of the first aspect, the method further includes:

[0027] If a shadowed area is detected on the user's face, the fourth of the plurality of overhead lights is turned on, and the shadowed area is within the illumination range of the fourth overhead light.

[0028] It should be understood that the illumination brightness of the fourth overhead light can be used to illuminate the shadowed areas of the user's face to even out the light intensity on the user's face. The number and specific location of the fourth overhead light can be determined based on the actual light intensity on the user's face.

[0029] Based on the above possible implementation methods, the fourth top light can be automatically lit according to the light intensity on the user's face. In scenarios such as makeup, the user does not need to hold a fill light, making it convenient to use. In addition, the lit fourth top light can eliminate shadow areas on the user's face, which can avoid makeup mistakes caused by insufficient or uneven lighting (such as unnatural whiteness, powdery makeup, or caking), further improving the user experience.

[0030] In one possible implementation of the first aspect, the method further includes:

[0031] In response to a user's first operation, the light source color of the at least one first top light is adjusted. The first operation includes at least one of voice command, touch operation, gesture operation, and selection of first information. The first information includes at least one of navigation information, scene information, time information, and weather information.

[0032] In one possible implementation of the first aspect, the method further includes:

[0033] If the first object is detected to be outside the illumination range of the at least one first top light, the fifth top light is turned on, and the first object is within the illumination range of the fifth top light and the at least one first top light.

[0034] Based on the above possible implementation methods, by illuminating the fifth dome light, the first object can be placed within the illumination range of the fifth dome light and at least one first dome light. This effectively achieves dome light following the first object and multi-area linkage illumination, achieving efficient matching between the dome light and the user's actual needs. It effectively solves the problem in the prior art that the user's reading position needs to be fixed within the illumination range of the reading light or that the user needs to manually switch the reading light, further enhancing the flexibility of the vehicle's dome light usage and improving the user experience.

[0035] In one possible implementation of the first aspect, the method further includes:

[0036] Turn off at least one sixth top light of the at least one first top light, and the first object is not within the illumination range of the sixth top light.

[0037] It should be understood that at least one sixth of the first ceiling lights can be turned off immediately, or at least one sixth of the first ceiling lights can be turned off gradually. Compared to rapidly turning off at least one sixth of the first ceiling lights, gradually turning off at least one sixth of the first ceiling lights after turning on the fifth ceiling light avoids visual discomfort caused by flickering and improves the user experience. At the same time, it can also reduce the impact of sudden current changes on electronic components and extend the lifespan of the ceiling lights.

[0038] Based on this possible implementation method, the dome light inside the vehicle can be turned on as needed, effectively avoiding unnecessary power consumption caused by turning on the dome light.

[0039] In one possible implementation of the first aspect, the method further includes:

[0040] If the duration during which the user's eye aspect ratio EAR is less than or equal to a second threshold reaches a first preset duration, the at least one first overhead light is turned off.

[0041] Based on the above possible implementation methods, when the EAR value is detected to be less than or equal to the second threshold, and the EAR value remains less than or equal to the second threshold after a first preset time, it can be determined that the user has closed their eyes and entered a sleep state. In order not to affect the user's sleep, at least one of the first dome lights can be automatically turned off, avoiding the user manually switching the lights on and off. This effectively solves the problem in practical applications where the user is asleep but the dome lights remain on, improving the user's lighting experience inside the vehicle. In addition, the above implementation method also helps to reduce the unnecessary on-time of the dome lights, which can extend the service life of the lamps.

[0042] In one possible implementation of the first aspect, the method further includes:

[0043] If the user's movement information using the first object meets a preset condition, the seventh top light among the plurality of top lights is turned on, and the first object is within the illumination range of the seventh top light and the at least one first top light.

[0044] It's not hard to understand that the seventh dome light can be any of the multiple dome lights installed inside the vehicle, excluding the first dome light.

[0045] The lit seventh ceiling light can also be one of the ceiling lights other than the first ceiling light. For example, the ceiling light corresponding to the user's movement information using the first object; or the ceiling light other than the first ceiling light corresponding to the user's current location.

[0046] Based on the above possible implementation methods, the problem of users being unable to quickly turn on the lights in situations such as insufficient interior lighting can be effectively solved, breaking the limitation of inflexible traditional switch operation settings.

[0047] Furthermore, the above-mentioned possible implementation methods can be applied to practical application scenarios such as multiple people reading or viewing electronic devices inside a vehicle. Users in different locations can independently control the lighting and extinguishing of the corresponding overhead lights according to the specific circumstances of their use of the first object, effectively realizing personalized lighting.

[0048] In one possible implementation of the first aspect, detecting that the user's use of the first object's movement information satisfies a preset condition includes:

[0049] The system detects that the user's movement range using the first object is greater than or equal to a preset range, the movement path length of the first object is greater than or equal to a preset length, and / or the number of movement positions of the first object is greater than or equal to a preset number.

[0050] It should be understood that the movement information may also include other information (such as movement speed and / or movement direction, etc.), and the specific content of the movement information is not limited in the embodiments of this application.

[0051] Secondly, this application provides a lighting control device, which may include:

[0052] A control unit is configured to illuminate at least one of the plurality of dome lights when it is detected that the interior of the vehicle is in a dark environment, a user is using a first object and the user's head is facing the first object, the first object being within the illumination range of the at least one dome light.

The first microphone device is within the illumination range of the second top light, and the second microphone device is within the illumination range of the third top light.

[0060] In some embodiments, the first object is a mirror, and the step of detecting that the interior of the vehicle is in a dark environment, the user using the first object and the user's head facing the first object includes: detecting that the interior of the vehicle is in a dark environment, the user unfolding the mirror and the user's head facing the mirror.

[0061] In some embodiments, the lighting control device further includes:

[0062] The second control subunit is used to turn on the fourth of the plurality of overhead lights when a shadow area is detected on the user's face, wherein the shadow area is within the illumination range of the fourth overhead light.

[0063] In some embodiments, the lighting control device further includes:

[0064] The second adjustment unit is used to adjust the light source color of the at least one first top light in response to a first operation by the user.

[0073] In some embodiments, detecting that the user's movement information using the first object meets preset conditions includes: detecting that the user's movement range using the first object is greater than or equal to a preset range, the movement path length of the first object is greater than or equal to a preset length, and / or the number of movement locations of the first object is greater than or equal to a preset number.

[0074] Thirdly, this application provides a vehicle including a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, causing the vehicle to perform the methods in any of the above aspects or any possible implementations of any of the above aspects.

[0075] Optionally, the vehicle may include a dome light, a camera or radar, and a dome light control system. The dome light may be installed in the rear row of the vehicle, and the camera or radar may be installed inside the vehicle. The dome light control system is used to execute the method in any of the above aspects or any possible implementation of any of the above aspects.

[0076] It should be understood that the number of interior dome lights may include one or more.

[0077] To meet the needs of different scenarios, multiple overhead lights can be deployed in the rear cabin ceiling using a zoned deployment approach.

[0078] For example, 19 dome lights can be installed in the rear cabin of the vehicle. These 19 dome lights can be divided into five groups: the first group of 5 dome lights and the second group of 5 dome lights are arranged alternately in the middle of the roof, covering the area directly above the rear seats; the third group of 5 dome lights is installed at the rear of the roof near the back of the rear seats; and a group of 2 dome lights are arranged on the ceiling above the seats on both sides, forming a three-dimensional lighting matrix that is dense in the middle and symmetrical on both sides.

[0106] The technical solutions of the embodiments of this application are described below with reference to the accompanying drawings and related embodiments. In the description of the embodiments of this application, the terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to limit the application. As used in the specification and appended claims of this application, the singular expressions "a," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of this application, "at least one" and "one or more" refer to one or more (including two). The term "and / or" is used to describe the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0107] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. The term "connection" includes direct connections and indirect connections, unless otherwise stated. "First" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0108] In the embodiments of this application, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0109] As smart cars and mobile office technologies become increasingly integrated, in-vehicle spaces are expanding from a single driving scenario to more diverse and multifunctional scenarios (such as office and living spaces). Taking the office scenario as an example, rear-seat passengers can conduct video conferences, process documents, and perform other tasks while driving. However, the in-vehicle environmental control system has not yet fully adapted to this new demand. For instance, traditional in-vehicle reading lights still require manual activation via physical buttons or touchscreen menus. When users are concentrating on their work, this operation method may distract them, affecting work efficiency and user experience. In practical applications, if rear-seat passengers are unfamiliar with the location or usage of physical buttons or touchscreen menus, the driver may need to provide guidance during the journey, potentially impacting driving safety.

[0110] Furthermore, the fixed lighting position of in-vehicle reading lights, which are activated via physical buttons or touchscreen menus, is difficult to adapt to the user's posture and cannot meet the visual needs of different postures. Therefore, the traditional control method of in-vehicle reading lights has restricted the experience in scenarios such as in-vehicle office work, and there is an urgent need to provide an intelligent lighting control to adapt to different visual needs in different scenarios.

[0111] To address the aforementioned issues, this application provides a lighting control method, a vehicle, and a readable storage medium. In this method, when the vehicle interior is detected to be dark, the user is using a first object (such as a paper document) and their head is continuously facing that object, the corresponding area's first overhead light is automatically turned on. The user does not need to turn the overhead light on or off via physical buttons or touchscreen menus, eliminating user intervention and effectively achieving automatic control of the vehicle's overhead light. Furthermore, by using three conditions—dark environment, user action, and focused gaze—invalid scenarios can be accurately excluded, avoiding interference caused by accidental light activation and improving the user experience.

[0112] The lighting control method provided in this application can be applied to vehicles. These vehicles can be equipped with lighting that automatically changes according to the user's different needs, thereby providing the user with a precise and comfortable riding experience.

[0113] In some examples, the means of transportation can include, but is not limited to, trains, cars, high-speed trains, subways, airplanes, buses, ships, cable cars, and other vehicles. Of course, the means of transportation can also be other vehicles designed for future technologies.

[0114] The lighting control method provided in this application embodiment can also be applied to a lighting control system. A lighting control system, also known as a lighting control system, may include lighting fixtures, data acquisition devices, and processing devices.

[0115] It should be understood that the data acquisition device can be used to collect information about the user (e.g., posture, facial light intensity, etc.) or the surrounding environment (e.g., brightness). The processing device can process the information collected by the data acquisition device to control the timing of the lighting's on / off state, brightness, color, and other changes.

[0116] Lighting lights can have different names depending on the application scenario. For example, when a user is reading in a vehicle cabin, the lighting light can be called a reading light. Furthermore, based on different functions, reading lights can be further subdivided into knee reading lights, table reading lights, or armrest reading lights, etc.

[0117] Data acquisition devices may include, but are not limited to, cameras, millimeter-wave radar, lidar, and sensors.

[0118] Processing devices may include one or more of the following: personal computer (PC), mobile phone, tablet computer, wearable device (e.g., watch, bracelet, helmet, smart glasses, etc.), augmented reality (AR) / virtual reality (VR) device, mixed reality (MR) device, laptop computer, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), in-vehicle computer, smart screen, etc. This application does not limit the specific type of processing device.

[0119] In one example, the data acquisition device can be directly electrically connected to the processing device via a wired connection. Alternatively, it can be wirelessly connected (e.g., via Bluetooth communication). The data acquisition device can also communicate with the processing device through other devices (e.g., cloud servers, base stations).

[0120] In other examples, the data acquisition and processing devices in a lighting control system can also be integrated into the same device. That is, the device has both data acquisition and information processing capabilities.

[0121] It's easy to understand that the specific forms of the data acquisition and processing devices in a lighting control system may be the same or different in different application scenarios. For example, in a scenario where a user works from their car, the data acquisition device could be a camera, and the processing device could be an onboard computer. In the aforementioned scenario of a user working from their car, the data acquisition device could also be a camera within the onboard computer, so that the onboard computer can be used for both data acquisition and information processing.

[0122] For ease of understanding, the following embodiments will be illustrated by taking the application of the lighting control method to a vehicle as an example.

[0123] First, let me introduce the vehicle involved in the embodiments of this application.

[0124] like Figure 1 The diagram shown is a structural schematic of a vehicle according to an embodiment of this application. The vehicle can be an internal combustion engine vehicle that uses an engine as a power source, a hybrid vehicle that uses both an engine and an electric motor as power sources, or an electric vehicle that uses an electric motor as a power source, etc.

[0125] See Figure 1 The vehicle 100 may include multiple subsystems, such as a control system 110, a sensing system 120, a communication system 130, a navigation system 140, an entertainment system 150, a drive system 160, and a computer system 170. Optionally, each system may include multiple components. Each system and component of the vehicle 100 can be interconnected via wired or wireless means.

[0126] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on vehicle 100. In other embodiments, vehicle 100 may include more or fewer systems or components than illustrated.

[0127] The control system 110 may also include a vehicle controller 111 for controlling the power system of the vehicle 100, and a steering system 112, throttle 113 and braking system 114 for controlling the vehicle 100.

[0128] The vehicle controller 111 can be used to coordinate and control the power battery and engine 161 of the vehicle 100 to improve the power performance of the vehicle 100.

[0129] The steering system 112 can be used to adjust the forward direction of the vehicle 100. For example, the steering system 112 can be a steering wheel system.

[0130] The throttle 113 can be used to control the operating speed of the engine 161 in order to control the speed of the vehicle 100.

[0131] The braking system 114 can be used to control the deceleration of the vehicle 100. For example, the braking system 114 can use friction to slow down the wheels 164.

[0132] The perception system 120 may include several sensors for sensing information about the surrounding environment of the vehicle 100. For example, the perception system 120 may include a global positioning system 121 (such as a global positioning system (GPS), a global navigation satellite system (GLONASS), a BeiDou navigation satellite system (BDS), a quasi-zenith satellite system (QZSS), and / or a satellite-based augmentation system (SBAS), etc.), an inertial measurement unit (IMU) 122, a lidar 123, a millimeter-wave radar 124, an ultrasonic radar 125, and a camera 126, etc. The perception system 120 may also include sensors that monitor the internal systems of the vehicle 100 (such as an in-vehicle air quality monitor, fuel gauge, oil temperature gauge, etc.). The vehicle 100 can obtain information about its current location, direction, speed, and surrounding environment through the perception system 120.

[0133] The Global Positioning System 121 can be used to estimate the geographical location of vehicle 100.

[0134] IMU122 can sense changes in the position and orientation of vehicle 100 based on inertial acceleration. In some embodiments, inertial measurement unit 122 may be a combination of accelerometer and gyroscope.

[0135] The lidar 123 can use lasers to sense objects in the environment in which the vehicle 100 is located. In some embodiments, the lidar 123 may include one or more laser sources, a laser scanner, and one or more detectors, as well as other system components.

[0136] The millimeter-wave radar 124 can use radio signals to sense objects in the surrounding environment of the vehicle 100. In some embodiments, in addition to sensing objects, the millimeter-wave radar 124 can also be used to sense the speed and / or direction of travel of objects. In some embodiments, the millimeter-wave radar 124 can also be used to sense the pose information of users or objects (e.g., books, mobile phones, etc.) in the vehicle 100.

[0137] The ultrasonic radar 125 can use ultrasonic signals to sense objects around the vehicle 100.

[0138] Camera 126 can be used to capture still images or videos of the environment surrounding vehicle 100. Objects are projected onto a photosensitive element through a lens, generating an optical image. The photosensitive element can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, which is then transmitted to an ISP (Internet Service Provider) for conversion into a digital image signal. The ISP outputs the digital image signal to a DSP (Digital Signal Processor) for processing. The DSP converts the digital image signal into image signals in standard RGB, YUV, or other formats. In some embodiments, camera 126 can also be used to capture information about users within vehicle 100 (such as user pose) and the location of objects.

[0139] In some embodiments, vehicle 100 may include one or N cameras 126, where N is a positive integer greater than 1.

[0140] In other examples, camera 126 may include a monocular camera, a binocular camera, a structured light camera, and a panoramic camera, etc.

[0141] The communication system 130 may include a wireless communication system that can communicate wirelessly with one or more devices via a communication network. For example, the wireless communication system may use 3G cellular communication, such as CDMA, EVDO, GSM / GPRS, or 4G cellular communication, such as LTE, or 5G cellular communication. For example, the wireless communication system may utilize WiFi or a wireless local area network (WLAN) for communication. In some embodiments, the wireless communication system may utilize an infrared link, Bluetooth, or ZigBee for communication.

[0142] The navigation system 140 may include map services provided by a map provider to provide navigation for the vehicle 100. The navigation system 140 may be used in conjunction with the vehicle's global positioning system 121, inertial measurement unit 122, etc. The map services provided by the map provider may be two-dimensional maps or high-precision maps.

[0143] The entertainment system 150 may include a display device 151, an audio module 152, a speaker 152A, a receiver 152B, a microphone 152C, a headphone jack 152D, a lighting module 153, etc.

[0144] The entertainment system 150 can implement audio functions, such as music playback and recording, through an audio module 152, a speaker 152A, a receiver 152B, a microphone 152C, a headphone jack 152D, and an application processor.

[0145] The audio module 152 can be used to convert digital audio information into analog audio signal output, or to convert analog audio input into digital audio signal. The audio module 152 can also be used for encoding and decoding audio signals.

[0146] The speaker 152A, also known as a "horn," is used to convert audio electrical signals into sound signals. The vehicle 100 can listen to music or make hands-free calls through the speaker 152A.

[0147] The receiver 152B, also known as the "earpiece," is used to convert audio electrical signals into sound signals. When vehicle 100 answers a phone call or voice message, it can do so by connecting the receiver 152B.

[0148] Microphone 152C, also known as a "microphone" or "voice transducer," is used to convert sound signals into electrical signals. When making a phone call or sending a voice message, the user can speak through microphone 152C, inputting the sound signal into microphone 152C. Vehicle 100 may be equipped with at least one microphone 152C. In some embodiments, vehicle 100 may be equipped with two microphones 152C, which, in addition to collecting sound signals, can also perform noise reduction. In other embodiments, vehicle 100 may be equipped with three, four, or more microphones 152C, which can collect sound signals, reduce noise, identify the sound source, and perform directional recording, etc.

[0149] The headphone jack 152D is used to connect wired headphones. The headphone jack 152D can be a Universal Serial Bus (USB) interface, or a 3.5mm Open Mobile Terminal Platform (OMTP) standard interface, or a CTIA (Cellular Telecommunications Industry Association of the USA) standard interface.

[0150] In some examples, the user's voice signal can also be acquired through a microphone, and the user can control certain aspects of the vehicle 100 by analyzing the user's voice signal, such as adjusting the interior temperature or playing music.

[0151] Display device 151 can be used to display images, videos, etc.

[0152] Optionally, the display device 151 is an actual display device, such as a central control screen. The display device 151 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Miniled LED, a MicroLED, a Micro-OLED, a quantum dot light-emitting diode (QLED), etc. In some embodiments, the vehicle 100 may include one or N display devices 151, where N is a positive integer greater than 1.

[0153] Optionally, the display device 151 can be a display device that projects onto an object using projection technology. For example, it can project onto the windshield of a vehicle using holographic projection or head-up display (HUD) technology, using the projection area on the windshield as the display device. This application does not specifically limit the type of display device.

[0154] The lighting module 153 can be used not only for general lighting but also to display richer functions in more diverse and multifunctional scenarios. For example, in a user reading scenario, the lighting module 153 can be illuminated at different locations based on changes in the user's posture. The lighting module 153 can be adjusted from area lighting to point lighting triggered by different events and scenarios. Of course, the illumination position, intensity, and / or lighting sequence of the lighting module 153 can also be precisely controlled according to instructions from the computer system 170, enabling flexible and intelligent interaction between the lighting module 153 and the user.

[0155] In some embodiments, the lighting module 153 may be a dome light installed inside the vehicle. It should be understood that the number of dome lights may include one or more. That is, one or more lighting modules 153 may be installed inside the vehicle.

[0156] To meet the needs of different usage scenarios, multiple dome lights can be deployed in the rear cabin ceiling using a zoned deployment method. Of course, in other possible implementations, multiple dome lights can also be deployed in the front passenger cabin and / or the driver's cabin; this application embodiment does not impose any limitations on this. The following embodiments of this application will illustrate the deployment of multiple dome lights in the rear cabin as an example.

[0157] like Figure 2 The diagram shown is a structural design schematic of a lighting module 153 provided in an embodiment of this application. See also... Figure 2 For example, 19 dome lights can be installed in the rear cabin of the vehicle. The 19 dome lights can be divided into five groups: the first group of 5 dome lights can be labeled as C1, C2, C3, C4 and C5 respectively; the second group of 5 dome lights can be labeled as D1, D2, D3, D4 and D5 respectively; the third group of 5 dome lights can be labeled as A1, A2, A3, A4 and A5 respectively; the fourth group of 2 dome lights can be labeled as B1 and B2 respectively; and the fifth group of 2 dome lights can be labeled as E1 and E2 respectively.

[0158] exist Figure 2 In the middle of the roof, five dome lights in the first group and five dome lights in the second group can be set at intervals to cover the area directly above the rear seats; five dome lights in the third group can be set at the rear of the roof near the back of the rear seats; and one set of dome lights (each set includes two lights) can be arranged on the ceiling above the seats on both sides, forming a dense lighting module 153 in the middle and symmetrical on both sides. This arrangement can achieve full coverage of the rear space and independent control of multiple areas.

[0159] The drive system 160 may include components that provide powered motion to the vehicle 100. In one embodiment, the drive system 160 may include an engine 161, an energy source 162, a transmission system 163, and wheels 164. The engine 161 may be an internal combustion engine, an electric motor, an air-compressed engine, or other types of engine combinations, such as a hybrid engine consisting of a gasoline engine and an electric motor, or a hybrid engine consisting of an internal combustion engine and an air-compressed engine. The engine 161 converts the energy source 162 into mechanical energy.

[0160] Energy source 162 may include gasoline, diesel, other petroleum-based fuels, propane, other compressed gas-based fuels, ethanol, solar panels, batteries, and other sources of electricity. Energy source 162 may also provide energy to other systems of vehicle 100.

[0161] The drivetrain 163 transmits mechanical power from the engine 161 to the wheels 164. The drivetrain 163 may include a gearbox, a differential, and a drive shaft. The drive shaft may include one or more axles that can be coupled to one or more wheels 164. In some examples, the drivetrain 163 may also include other components, such as a clutch.

[0162] Some or all of the functions of vehicle 100 are controlled by computer system 170. Computer system 170 may include at least one processor 171. Processor 171 may include one or more processing units, such as: application processor (AP), modem processor, graphics processing unit (GPU), image signal processor (ISP), controller, video codec, digital signal processor (DSP), baseband processor, and / or neural network processing unit (NPU), etc. Different processing units may be independent devices or integrated into one or more processors.

[0163] The controller can generate operation control signals based on the instruction opcode and timing signals to complete the control of instruction fetching and execution.

[0164] Processor 171 may also include memory for storing instructions and data. In some examples, the memory in processor 171 is a cache memory. This memory can hold instructions or data that processor 171 has just used or is recurring. If processor 171 needs to use the instruction or data again, it can retrieve it directly from memory. This avoids repeated accesses, reduces the waiting time of processor 171, and thus improves system efficiency.

[0165] In some examples, processor 171 can control certain functions of vehicle 100 based on information acquired by various subsystems (such as perception system 120, navigation system 140, etc.). For example, processor 171 can analyze the information acquired by various subsystems to determine the user's pose in order to control the corresponding lighting module 153 to turn on or off.

[0166] The lighting control method provided in this application embodiment will be described in detail below with reference to the corresponding accompanying drawings and specific application scenarios.

[0167] like Figure 3 The diagram shown is a schematic flowchart of a lighting control method 300 provided in an embodiment of this application. Before introducing the lighting control method 300 provided in this embodiment, a brief description of the executing entity involved in this embodiment will be given. Figure 3The aforementioned lighting control method 300 can be executed by a vehicle, specifically by an on-board device within the vehicle; it can also be executed by a module applied within the vehicle (such as a processor, chip, or chip system); or it can be implemented by a logic module or software capable of realizing all or part of the vehicle's functions. This application does not limit this specific implementation.

[0168] The aforementioned lighting control method 300 can be applied to the aforementioned Figure 1 The vehicle shown may be equipped with multiple dome lights, which can provide lighting support for the interior environment.

[0169] In this embodiment of the application, the specific installation positions of the multiple dome lights inside the vehicle can be exactly the same. For example, the multiple dome lights can be arranged sequentially on the top of the vehicle cabin.

[0170] In some embodiments, the specific locations of the multiple dome lights inside the vehicle may be partially the same and partially different. For example, at least one of the multiple dome lights may be located on the top of the vehicle cabin, while the other dome lights may be located on the sides of the vehicle cabin, i.e., on the side walls of the vehicle frame. Of course, in other embodiments, the specific locations of the multiple dome lights inside the vehicle may be completely different. This application does not specifically limit this.

[0171] See Figure 3 The lighting control method 300 may include the following step S310:

[0172] S310, when it is detected that the interior of the vehicle is in a dark environment, the user is using the first object and the user's head is facing the first object, at least one of the multiple dome lights is turned on, and the first object is within the illumination range of the at least one dome light.

[0173] It should be understood that the interior of a vehicle may include spaces such as the driver's cabin (including the area for the driver's or passenger's seat), the rear passenger cabin, and the living area (or living cabin) of a motorhome.

[0174] In some embodiments, sensors installed on the vehicle can be used to detect the dark environment inside the vehicle. For example, an ambient light sensor (ALS), an infrared sensor, or a multispectral sensor array.

[0175] In this embodiment, a dark environment inside the vehicle can mean that the light intensity inside the vehicle is less than or equal to a preset light intensity threshold. The specific value of the preset light intensity threshold can be user-defined or pre-configured. This embodiment does not impose specific limitations on this.

[0176] It's easy to understand that when the light intensity inside the car is less than or equal to a preset light intensity threshold, the car interior is considered dark, making it difficult for users to identify objects.

[0177] In one example, a dark environment inside a vehicle can be caused by insufficient natural light. For instance, the vehicle is being driven at night and the dome lights are not turned on.

[0178] In another example, darkness inside a vehicle can also be caused by physical obstructions. For instance, when a vehicle passes through a tunnel, the tunnel blocks sunlight, resulting in darkness inside the vehicle. Alternatively, darkness can occur when the vehicle doors are closed, the windows or sunroof are set to full blackout mode, or the sunshade is completely closed.

[0179] It's easy to understand that when the interior of the vehicle is dark, combined with other conditions (including the user using the first object and the user's head facing the first object), it can be determined whether to turn on at least one first dome light. That is, using the dark interior environment of the vehicle as one of the conditions for turning on at least one first dome light can avoid unnecessary lighting when the interior of the vehicle is well lit, reducing power consumption. Based on this, it can also effectively reduce the usage time of the interior dome light and extend the life of the dome light.

[0180] In some embodiments, the first object may include, but is not limited to, paper materials (such as books, documents, etc.), electronic devices (such as mobile phones, laptops, e-book readers, wristbands, watches, etc.), mirrors, sound pickup devices (such as microphones, etc.), tables and chairs (such as folding trays on the back of chairs), food, kitchen knives, household appliances, and any other object. This application does not limit the specific type of the first object in its embodiments.

[0181] In some embodiments, an installed camera or radar (e.g., millimeter-wave radar) can be used to detect whether a user is using the first object.

[0182] For example, a camera or radar can be used to acquire images (or videos, etc.) including the user (or any limb of the user) and / or a first object, and the acquired images can be processed and analyzed to determine whether the user is using the first object.

[0183] In one possible example, whether the distance between the user's limb and the first object in the acquired image is less than or equal to a preset distance can be detected to determine whether the user is using the first object. For example, if the distance between the user's limb and the first object is less than or equal to the preset distance, then it can be determined that the user is using the first object.

[0184] In the above examples, the specific value of the preset distance can be user-defined or pre-configured. This application embodiment does not limit the specific value of the preset distance or the corresponding length unit.

[0185] In practical applications, different preset distances can be set for different first objects. For example, if the first object is paper material, the preset distance can be set to 0 centimeters. Or, if the first object is a mirror, the preset distance can be set to 5 centimeters.

[0186] As an example, and not a limitation, the specific value of the preset distance can be greater than or equal to 0 centimeters. Furthermore, when the preset distance is 0 centimeters, it can indicate that the user's limb is in direct contact with the first object. When the preset distance is greater than 0 centimeters, it can indicate that the user's limb is approaching (or gradually approaching) the first object.

[0187] In another possible example, the usage status of the first object in the acquired image can also be detected to determine whether the user is using the first object. For example, if the first object is a mirror, and the mirror is unfolded, then it can be determined that the user is using the mirror. Similarly, if the first object is a small tabletop, and the tabletop is unfolded, then it can be determined that the user is using the tabletop.

[0188] It's easy to understand that a user's use of a first object can be determined specifically based on different types of first objects. The following examples illustrate how users might use the aforementioned first objects: paper documents, electronic devices, mirrors, microphones, and small tables.

[0189] In some embodiments, when the first object is paper material, the user's use of the paper material may include the user holding the paper material in an unfolded state with their hand.

[0190] It's easy to understand that you can determine whether a user is holding a paper document by the distance between their hand and the paper document or by the posture of their hand.

[0191] It should be understood that an unfolded paper document can be either open or flat. Conversely, if the paper document is not in use, it can be closed. In this embodiment, an unfolded paper document facilitates user access to the document.

[0192] In some embodiments, it can be determined whether the paper document is in an unfolded state by at least one of the following methods: the page content of the paper document, whether the paper document is in a laid-out state, the edges and shape of the paper document.

[0193] In another example, where the first object is an electronic device, user use of the electronic device can include the user holding the electronic device with its screen on. That is, if the user is holding the electronic device with its screen on, it can be determined that the user is using the electronic device.

[0194] It should be understood that in this example, whether a user is holding an electronic device can be determined by the user's hand posture information or the distance between the user's hand and the electronic device.

[0195] In some embodiments, whether the electronic device is in a screen-on state can be determined by performing pixel detection on the acquired image of the electronic device. Alternatively, it can be determined by detecting whether the content displayed on the electronic device's screen changes. Or, it can be determined directly by using a sensor to detect the brightness of the electronic device's screen.

[0196] In another example, if the first object is a mirror, the user's use of the mirror can include the mirror inside the vehicle changing from a folded state to an unfolded state. That is, the user's use of the mirror can be determined when the mirror is in the unfolded state. Based on this, when any of the user's limbs approaches the mirror, the mirror surface can display the image corresponding to any limb (such as the face).

[0197] It should be understood that in the structural design of a vehicle, the mirror can be mounted on the frame in a folding manner, or embedded in a small table in a folding manner. Based on this, when the user unfolds the mirror, changing the folded state to the unfolded state, it can be determined that the user is using the mirror.

[0198] In another example, where the first object is a microphone, the user's use of the microphone may include the user holding the microphone with their hand.

[0199] It should be understood that, in one example, the sound pickup device can be a device with only sound pickup function, such as a microphone, walkie-talkie, etc. In another example, the sound pickup device can also be a device with both sound pickup and display functions. Examples include mobile phones, personal digital assistants, tablets, in-vehicle computers, laptops, smart screens, super mobile personal computers, wearable devices, and other electronic devices. Of course, the sound pickup device can also be other devices oriented towards future technologies. This application does not impose any limitations on the specific type of sound pickup device.

[0200] Of course, in other embodiments, the user's use of the pickup device may also include the user holding the pickup device in the pickup state with their hand.

[0201] Compared to the aforementioned example where the user holds the microphone in their hand, in this example, the user holds the microphone while it is in microphone-collecting mode. It's easy to understand that a microphone in microphone-collecting mode can directly acquire the user's voice signal. In other words, in this embodiment, not only does the user need to hold the microphone, but the microphone must also be actively collecting audio. This allows for more accurate identification of user use of the microphone, avoiding the potential for misidentification due to moving the microphone, thus saving power.

[0202] In some embodiments, the pickup state of the pickup device can be activated by triggering a physical button on the pickup device; it can also be activated by the user triggering a menu option on the display screen; or it can be activated directly after a communication connection is established between the pickup device and other devices (such as playback devices or in-vehicle devices).

[0203] In other examples, where the first object is a small table, user use of the small table may include the user unfolding a small table that is currently folded inside the vehicle. It should be understood that the small table can be folded when the user is not using it; when the user uses the small table, it can change from a folded state to an unfolded state, allowing the user to carry other items (such as a makeup mirror, water cup, etc.). In other words, it can be determined that the user is using the small table when it is unfolded.

[0204] It should be noted that the user may also be determined as another first object based on actual application requirements, and this application embodiment does not specifically limit this.

[0205] In this embodiment, when the user's head is facing the first object, it can be further determined that the user is effectively using the first object. That is, the first overhead light corresponding to the position of the first object is automatically turned on only when all three conditions are met simultaneously: the environment is dark, the user is using the first object, and the user's head is facing the object. This accurately eliminates invalid scenarios such as the user holding a book but not reading it, or the user holding an electronic device but looking out the window, effectively identifying the user's actual needs, reducing unnecessary light interference, ensuring efficient matching of light energy with the user's actual needs, and optimizing the user experience.

[0206] In some embodiments, in addition to determining whether a user is effectively using the first object by observing whether their head is facing the first object, the user's gaze can also be focused on the first object as a criterion for determining whether the user is effectively using the first object. That is, the user's head facing the first object can include the user's gaze being focused on the first object.

[0207] In some embodiments, the user's head posture or key points on the user's face can be detected to determine whether the user's head is facing the first object or whether the user's gaze is focused on the first object.

[0208] In this embodiment of the application, the interior of the vehicle may be provided with multiple dome lights, wherein the first dome light is one or more dome lights that are turned on when the interior of the vehicle is detected to be in a dark environment, the user is using a first object and the user's head is facing the first object.

[0209] It should be noted that the number of first ceiling lights illuminated in this embodiment is not arbitrarily determined or preset (i.e., fixed), but is associated with the position of the first object. In other words, it is not possible to indiscriminately illuminate one or more ceiling lights at arbitrary fixed positions simply as long as the aforementioned conditions are met. This could result in the illuminated ceiling lights failing to meet the user's actual usage needs.

[0210] Therefore, in this embodiment of the application, if it is detected that the interior of the vehicle is in a dark environment, the user is using the first object and the user's head is facing the first object, then at least one of the multiple dome lights can be lit according to the position of the first object, so that the illumination range of the lit at least one dome light can completely cover the first object.

[0211] In other words, at least one first dome light can be precisely illuminated according to the user's actual application needs. This way, when a user is engaged in activities such as reading inside the vehicle, their posture is no longer restricted by the fixed position of the dome light. This significantly enhances the user's lighting experience in the vehicle cabin environment, creating a more comfortable, convenient, and personalized lighting environment.

[0212] In one example, the location of the first object can be detected using any of the following algorithms: YOLO (you only look once) object detection algorithm, neural network-based feature extraction and fusion algorithm, Hungarian algorithm (Kuhn-Munkres), image segmentation algorithm, and key point detection and point cloud annotation algorithm.

[0213] In some embodiments, if the first object is detected not to be within the illumination range of at least one first top light, a fifth top light may be turned on, so that the first object may be within the illumination range of the fifth top light and at least one first top light.

[0214] It should be understood that in practical applications, the position of the first object may change with the user's pose. When the first object is detected to be outside the illumination range of one or more first top lights, the position of the first object can be reacquired, and the fifth top light can be lit based on the reacquired position of the first object, so that the illumination range of one or more first top lights and the fifth top light can cover the first object.

[0215] In one example, any one of the following algorithms can be used to detect whether the first object is within the illumination range of at least one first top light: dynamic bounding box adjustment algorithm, 3D collision detection algorithm, fuzz detection algorithm, and threshold detection algorithm.

[0216] It's easy to understand that the number of lit fifth lights can be one or more. In practical applications, this can be determined by the specific location of the first object.

[0217] like Figure 4 The diagram shown is a schematic representation of a process for lighting the first and fifth ceiling lights according to an embodiment of this application. (See also...) Figure 4 If the first condition is met, the position of the first object can be obtained so that at least one first top light can be lit according to the position of the first object; then if the first object is not within the illumination range of at least one first top light, the position of the first object can be obtained again so that the fifth top light can be lit.

[0218] It should be understood that the aforementioned first condition may refer to detecting that the vehicle interior is in a dark environment, the user is using the first object, and the user's head is facing the first object. In other words, if the conditions of detecting that the vehicle interior is in a dark environment, the user is using the first object, and the user's head is facing the first object are met, the position of the first object can be obtained so that at least one first dome light can be illuminated based on the position of the first object.

[0219] Conversely, if the first condition is not met, any of the interior lights can be left off.

[0220] It should be noted that during the execution of the lighting control method 300 provided in the above-described embodiments of this application, the situation where the interior ceiling light is triggered and illuminated by other users can be avoided.

[0221] For example, if the vehicle interior is not detected to be dark, and the user is using the first object with their head facing it, no interior lights need to be turned on. However, if the user opens a door, the preset reading light or footwell ambient light can be activated in response. Alternatively, if the vehicle is detected to be unlocked, the preset interior lights can be activated in response. Or, if the user opens the refrigerator door, the corresponding light can be activated in response to the opening of the refrigerator door.

[0222] Of course, the priority of the lighting control method 300 provided in the above-described embodiments of this application and the situation mentioned in the foregoing example where the interior dome light is triggered by another user's operation can also be set. That is, in some examples, higher priority events can be executed first, and then lower priority events can be executed after the higher priority events have been completed.

[0223] For example, assuming that the priority of executing the lighting control method 300 provided in this application embodiment is higher than the priority of opening the refrigerator door and turning on the corresponding light, if the vehicle interior is detected to be in a dark environment, and the user is using a first object with their head facing the first object, the first dome light that needs to be turned on is dome light X; if the user opens the refrigerator door and the first dome light that is turned on is also dome light X, then based on the priority order, if the vehicle interior is detected to be in a dark environment, and the user is using a first object with their head facing the first object, then the first dome light X can be turned on first, until the first dome light X turns off under certain conditions (such as the user falling asleep or the first object being outside the illumination range of the first dome light X, as mentioned later). If the refrigerator door is still open, then the first dome light X can continue to be turned on. Conversely, if the refrigerator door is closed after the first dome light X turns off under certain conditions, then the first dome light X can remain off.

[0224] Similarly, in Figure 4 In the case where the first object is within the illumination range of at least one first top light, at least one first top light may continue to be lit, that is, one or more first top lights may remain lit.

[0225] In some embodiments, if the first object is detected to be outside the illumination range of at least one first top light, a fifth top light may be turned on and at least one sixth top light among at least one first top light may be turned off, so that the first object may not be within the illumination range of the turned-off sixth top light.

[0226] It should be understood that when the vehicle interior is detected to be in a dark environment, and the user is using the first object with their head facing the first object, multiple first overhead lights can be illuminated. As the user's posture changes, the position of the first object may exceed the illumination range corresponding to the multiple first overhead lights. Based on this, by illuminating a fifth overhead light (in addition to the multiple first overhead lights), the first object can be brought back into the illumination range of the fifth overhead light and at least one first overhead light.

[0227] In some examples, after the position of the first object changes, some or all of the at least one lit first ceiling light may not need to remain lit continuously. In this case, some or all of the first ceiling lights can be turned off. In this embodiment, the turned-off part or all of the first ceiling lights can be understood as the sixth ceiling light. After the sixth ceiling light is turned off, the first object whose position has changed will no longer be within the illumination range of the sixth ceiling light.

[0228] In the above embodiments, the sixth ceiling light can be turned off immediately after the fifth ceiling light is turned on; alternatively, the sixth ceiling light can be turned off gradually after the fifth ceiling light is turned on. Compared to quickly turning off the sixth ceiling light, gradually turning off the sixth ceiling light after turning on the fifth ceiling light can avoid visual discomfort caused by flickering, and at the same time, it can reduce the impact of sudden current changes on electronic components and extend the service life of the ceiling light.

[0229] Based on this possible implementation method, it is possible to turn the roof lights on or off as needed, effectively avoiding unnecessary energy consumption caused by turning on the roof lights.

[0230] In some embodiments, at least one first overhead light may be turned off if the duration for which the user's eye aspect ratio (EAR) is detected to be less than or equal to a second threshold reaches a first preset duration.

[0231] It should be understood that EAR is a geometrical proportional parameter used to describe the morphological characteristics of the eyeball, as can be seen in the following formula (1):

[0232]

[0233] See Figure 5 In the above formula (1), A can represent the vertical distance between the coordinates of the periorbital feature points P2 and P6; B can represent the vertical distance between the coordinates of the periorbital feature points P3 and P5; and C can represent the horizontal distance between the coordinates of the periorbital feature points P1 and P4.

[0234] It's not hard to understand, see Figure 6Based on the above formula (1), the 2D coordinates of the user's face can be constructed, the vertical distances A (P2, P6) and B (P3, P5) of the user's eyes can be obtained, and the horizontal distances C (P1, P4) of the user's eyes can be obtained. Then, the EAR can be calculated based on the obtained distances A (P2, P6), B (P3, P5) and C (P1, P4). If the duration of the EAR being less than or equal to the second threshold reaches the first preset duration, it can be determined that the user has fallen asleep and at least one first overhead light can be turned off; otherwise, at least one first overhead light can be kept on.

[0235] In other words, if the value of EAR in the above formula (1) is less than or equal to the second threshold, and the value of EAR determined based on the user's facial 2D coordinates after the first preset time is still less than or equal to the second threshold, it can be determined that the user has closed their eyes and entered a sleep state. In order not to affect the user's sleep, at least one first overhead light can be automatically turned off.

[0236] Conversely, when the value of EAR is greater than the second threshold, it can be determined that the user's eyes are open (or not closed), and in this case, at least one first overhead light can be continuously lit.

[0237] In this embodiment, the first preset duration can be user-defined or pre-configured. For example, the first preset duration can be 1 minute, 2 minutes, 3 minutes, etc. This application embodiment does not limit this.

[0238] In some embodiments, the specific value of the second threshold can be 0.2 to 0.25, for example, 0.2, 0.21, 0.22, 0.24, 0.25, etc. This application embodiment does not limit the specific value of the second threshold.

[0239] It is worth noting that if the lit ceiling lights include one or more first ceiling lights and other ceiling lights (e.g., the fifth ceiling light) before the user's EAR is detected to be less than or equal to the second threshold for a period of time that reaches the first preset duration, then all ceiling lights (including one or more first ceiling lights and other ceiling lights) can be turned off when the user's EAR is detected to be less than or equal to the second threshold for a period of time that reaches the first preset duration.

[0240] For example, if the vehicle interior is detected to be in a dark environment, the user is using the first object, and the user's head is facing the first object, then the light is turned on. Figure 2One of the multiple overhead lights shown is a first overhead light B2. Then, if a first object is detected not within the illumination range of the first overhead light B2, the fifth overhead light B1 and the fifth overhead light C3 are illuminated. Based on this, the first object can be within the illumination range of the first overhead light B2, the fifth overhead light B1, and the fifth overhead light C3. After a preset time, if the user's EAR is detected to be less than or equal to a second threshold for a period of time that reaches a first preset time, the currently illuminated first overhead light B2, the fifth overhead light B1, and the fifth overhead light C3 can be immediately turned off to avoid disturbing the user's rest.

[0241] In other embodiments, if the user's EAR is detected to be less than or equal to a second threshold, at least one first ceiling light may be turned off directly, or all ceiling lights, including at least one first ceiling light, may be turned off.

[0242] In some embodiments, at least one overhead light corresponding to the user's eye may be turned off when the duration of time during which the user's EAR is detected to be less than or equal to the second threshold reaches a first preset duration, or when the user's EAR is less than or equal to the second threshold.

[0243] Of course, in some embodiments, at least one overhead light corresponding to the user's location may be turned off when the user's EAR is detected to be less than or equal to the second threshold for a period of time that reaches the first preset duration, or when the user's EAR is less than or equal to the second threshold.

[0244] For example, suppose there are two users in the rear cabin. The first user is in the rear cabin behind the driver's seat, and the second user is in the rear cabin behind the front passenger seat. If the vehicle interior is detected to be dark, and the first user is using a book with their head facing the book, then the lights are turned on. Figure 2 The first dome light B2 and the first dome light C2 shown herein illuminate when the vehicle interior is detected to be in a dark environment, the second user is using an electronic device, and the first user's head is facing the electronic device. Figure 2 As shown in the diagram, if the duration for which the EAR of the first user is less than or equal to the second threshold reaches the first preset duration, then the first overhead lights B2 and C2 corresponding to the location of the first user can be turned off. However, if the duration for which the EAR of the second user is less than or equal to the second threshold does not reach the first preset duration, then the first overhead lights E2 and D2 corresponding to the location of the second user can remain on.

[0245] It is easy to understand that the above possible implementation methods can be applied to practical application scenarios such as multiple people reading or viewing electronic devices inside a vehicle. Furthermore, the corresponding dome light can be independently controlled to turn on and off for users in different locations based on the specific circumstances of their use of the first object, effectively achieving personalized lighting.

[0246] In some embodiments, if the user's movement information of the first object meets a preset condition, the seventh top light among the multiple top lights can be turned on so that the first object is within the illumination range of the seventh top light and at least one first top light.

[0247] It should be understood that movement information may include, but is not limited to, at least one of movement amplitude, movement path length, and / or number of movement locations. That is, detecting that the movement information of the user using the first object meets preset conditions may include: detecting that the user's movement amplitude using the first object is greater than or equal to a preset amplitude, the movement path length of the first object is greater than or equal to a preset length, and / or the number of movement locations of the first object is greater than or equal to a preset number.

[0248] In other examples, the movement information may also include other information (such as movement speed and / or movement direction, etc.), and the specific content of the movement information is not limited in the embodiments of this application.

[0249] In one example, if it is detected that the user moves the first object by a distance greater than or equal to a preset distance, then the seventh dome light among the multiple dome lights installed in the vehicle can be turned on.

[0250] Among them, probabilistic graphical model (such as Hidden Markov Model or Bayesian Network) algorithms, deep learning algorithms (such as Spatiotemporal Two-Stream Algorithm or Graph Convolutional Network) or artificial intelligence (AI) algorithms can be used to detect the user's movement amplitude using the first object.

[0251] In another example, if it is detected that the length of the user's movement path using the first object is greater than or equal to a preset length, then the seventh top light among multiple top lights can also be lit.

[0252] It should be understood that any of the following algorithms can be used to detect the length of the user's movement path using the first object: hand tracking algorithm (e.g., optical flow, deep learning object detection model, etc.), 3D spatial trajectory reconstruction algorithm (e.g., point cloud registration algorithm, etc.), or trajectory integration algorithm.

[0253] In another example, if the number of times the user moves the first object is greater than or equal to a preset number, then the seventh top light among multiple top lights can also be lit.

[0254] It is easy to understand that the number of movement positions of the first object can be obtained based on the movement speed of the first object, or it can be obtained using attitude estimation algorithms, feature point matching and tracking algorithms, etc. This application does not limit this.

[0255] In some embodiments, the seventh dome light can be all the dome lights other than the first dome light among the multiple dome lights installed inside the vehicle. Based on this, if the movement information of the user using the first object is detected to meet a preset condition, all the dome lights inside the vehicle can be turned on. That is, the preset condition can be a trigger action to turn on all the dome lights inside the vehicle.

[0256] In other embodiments, the lit seventh ceiling light can be some of the ceiling lights other than the first ceiling light. That is, the number of lit seventh ceiling lights may not be equal to the total number of ceiling lights minus the number of lit first ceiling lights.

[0257] For example, the lit seventh dome light could be a dome light corresponding to the user's movement information of the first object. Taking the movement information as the length of the movement path as an example, the lit seventh dome light could be a dome light on the movement path of the first object, that is, the illumination range of the lit seventh dome light and at least one first dome light covers the movement path of the first object.

[0258] For example, the seventh ceiling light can also be any of the ceiling lights except the first one, corresponding to the user's location.

[0259] This is an example, not a limitation. Assume... Figure 2 The vehicle shown has a total of 19 overhead lights in the rear, 10 of which correspond to the rear cabin behind the driver's seat. Figure 2 The dome lights C1, C2, C3, C4, C5, B1, B2, A2, A3, and A5 are configured such that if a user is sitting in the rear seat behind the driver's seat, and the vehicle interior is detected to be in a dark environment, and the user is using the first object with their head facing the first object, then if the user's movement information using the first object meets preset conditions, other dome lights corresponding to the rear seat behind the driver's seat can also be lit. That is, in addition to lighting the first dome light B2, the seventh dome lights C1, C2, C3, C4, C5, B1, A2, A3, and A5 can also be lit.

[0260] The following will introduce the practical application scenarios of the aforementioned lighting control method 300 using several possible examples. It should be understood that the embodiments of this application are not limited to the application scenarios described below, and can also be applied to other application scenarios requiring lighting, such as cooking lighting in a motorhome. The embodiments of this application do not limit this application.

[0261] First, the primary object can be paper-based materials.

[0262] like Figure 7 The diagram shown is a schematic representation of a user reading paper documents according to an embodiment of this application. Figure 8 The image shown is a schematic diagram illustrating a scenario where a ceiling light corresponding to a user reading printed materials is illuminated, according to an embodiment of this application. See also... Figure 7 and Figure 8 Assuming the printed material is a book, the system can activate the light if it detects that the vehicle interior is dark, the user's hands are holding an open book, and the user's head is facing the book. Figure 8 The first overhead light B2 shown allows the book to be placed within the illumination range of the first overhead light B2. Figure 8 The illumination range of the first overhead light B2 can be represented by a dashed circle.

[0263] In the above example, it can be based on Figure 7 or Figure 8 The first overhead light B2 is illuminated at the location of the book. In one possible example, the position of the user's hand holding the book can be obtained first, and then the first overhead light B2 can be illuminated based on the obtained position of the user's hand holding the book, so that the illumination range of the first overhead light B2 can cover the book held by the user's hand.

[0264] In some embodiments, see Figure 9 Furthermore, if the book is detected to be outside the illumination range of the first top light B2, the fifth top light C3 can be turned on, allowing the book to be within the illumination range of both the fifth top light C3 and the first top light B2.

[0265] In other words, an electronic fence can be established for the book held by the user's hand. If the book is detected to be outside the range of the electronic fence, the position of the book held by the user's hand can be obtained again. Then, based on the obtained position of the book held by the user's hand, the fifth top light C3 is lit up, so that the book whose position has changed can be within the illumination range of the fifth top light C3 and the first top light B2.

[0266] It should be understood that the area of ​​the electronic fence can correspond to the illumination range of the first top light B2. Books outside the electronic fence can be understood as the book's location being partially or entirely outside the electronic fence's area.

[0267] After illuminating the first overhead light B2 based on the aforementioned steps, the system can continue to monitor the book held by the user. If the book remains within the illumination range of the first overhead light B2, then B2 will remain illuminated. Conversely, if the book is not within the illumination range of the first overhead light B2, the corresponding fifth overhead light C3 can be illuminated based on the book's current position. This allows both the first overhead light B2 and the fifth overhead light C3 to illuminate the book, providing lighting support for the user's reading.

[0268] Based on the above possible implementation methods, the lighting of the fifth dome light C3 in the direction adjacent to the lighting range of the first dome light B2 can be invoked, which can effectively realize target (i.e., the lighting and the first object) tracking and multi-area linkage lighting, further enhancing the flexibility of the dome light invocation.

[0269] In some other embodiments, after the fifth ceiling light C3 is turned on, the first ceiling light B2 can also be turned off.

[0270] For example, see Figure 10 Assuming that the fifth top light C3 has a large illumination range, meaning that turning on the fifth top light C3 can completely illuminate the book held by the user's hand, then if it is detected that the book held by the user's hand is not within the illumination range of the first top light B1, the fifth top light C3 can still be turned on according to the position of the book held by the user's hand at this time, so that the book held by the user's hand can be within the illumination range of the fifth top light C3. After that, the first top light B2 can be turned off.

[0271] It is not difficult to understand the above. Figure 7 and Figure 8 In the example shown, there is one lit first ceiling light (corresponding to first ceiling light B2), and if a book is detected not within the illumination range of first ceiling light B2, there is also one lit fifth ceiling light (corresponding to fifth ceiling light C3). Therefore, if the illumination range of fifth ceiling light C3 is large enough, first ceiling light B2 can be turned off after fifth ceiling light C3 is turned on. In this case, the turned-off first ceiling light B2 can also be understood as all the ceiling lights in at least one first ceiling light.

[0272] In other examples, when multiple first overhead lights are lit, if the book held by the user is not within the illumination range of the multiple first overhead lights (including first overhead light B2), one or more sixth overhead lights can be turned off after the fifth overhead light is lit, depending on the actual application requirements. Based on the foregoing Figures 7 to 10 In the example shown, the sixth overhead light that is turned off can be the first overhead light B2.

[0273] The above Figure 9 and Figure 10 In the example shown, the first overhead light B2 can be turned off immediately or gradually. Compared to turning off the first overhead light B2 quickly, gradually turning off the first overhead light B2 after turning on the fifth overhead light C3 can avoid the visual discomfort caused by flickering. At the same time, it can also reduce the impact of sudden current changes on electronic components and extend the life of the overhead light.

[0274] In some embodiments, see Figure 11 If the user's EAR is detected to be less than or equal to the second threshold, the first overhead light B2 can be turned off.

[0275] The specific details of EAR1, the second threshold, and the first preset duration can be found in the descriptions of the aforementioned related embodiments, and will not be repeated here.

[0276] It is easy to understand that if the illuminated dome lights in the vehicle include the first dome light B2 and the fifth dome light C3 before the user's EAR is detected to be less than or equal to the second threshold, then the first dome light B2 and the fifth dome light C3 can be turned off when the user's EAR is detected to be less than or equal to the second threshold.

[0277] In some embodiments, the first overhead light B2 may be turned off if the duration for which the user's EAR is detected to be less than or equal to the second threshold reaches the first preset duration.

[0278] Similarly, if the illuminated dome lights in the vehicle include not only the first dome light B2 but also the fifth dome light C3 before the duration of detecting that the user's EAR is less than or equal to the second threshold reaches the first preset duration, then the first dome light B2 and the fifth dome light C3 can be turned off when the duration of detecting that the user's EAR is less than or equal to the second threshold reaches the first preset duration.

[0279] In other embodiments, if the movement information of the book held by the user's hand meets the preset conditions, the seventh top light among the multiple top lights can also be lit, and the book held by the user's hand can be within the illumination range of the seventh top light and the first top light B2.

[0280] It should be understood that the specific content of the mobile information and the relevant content of lighting the seventh lamp can be found in the description of the aforementioned related embodiments, and will not be repeated here.

[0281] In some embodiments, the seventh dome light can be one of multiple dome lights installed inside the vehicle; that is, the seventh dome light is all the dome lights except for the first dome light B2. Based on this, if the movement information of the book held by the user's hand meets preset conditions, all the dome lights inside the vehicle can be turned on. In other words, the movement information of the book held by the user's hand can be the trigger action to turn on all the dome lights.

[0282] by Figure 2 Taking a vehicle with 19 overhead lights as an example, assuming the movement information is the length of the movement path, then if the movement path length of the book held by the user's hand meets the preset conditions, the following overhead lights can be lit: the first overhead light B2, the seventh overhead light C1, the seventh overhead light C2, the seventh overhead light C3, the seventh overhead light C4, the seventh overhead light C5, the seventh overhead light B1, the seventh overhead light A1, the seventh overhead light A2, the seventh overhead light A3, the seventh overhead light A4, the seventh overhead light A5, the seventh overhead light D1, the seventh overhead light D2, the seventh overhead light D3, the seventh overhead light D4, the seventh overhead light D5, the seventh overhead light E1, and the seventh overhead light E2.

[0283] In other embodiments, the lit seventh ceiling light may be one of the ceiling lights other than the first ceiling light B2.

[0284] In one example, the lit seventh dome light could be a dome light that corresponds to the movement of the book held by the user's hand.

[0285] See, as an example rather than a limitation. Figure 12 Assuming the movement information is the number of movement locations, Figure 12 The text uses dashed lines to represent the number of positions the user's hand moves while holding the book. If the detected number of these positions meets a preset condition, nine seventh top lights will illuminate. The illumination range of these nine lights can cover multiple positions the user's hand is moving while holding the book. Specifically, the nine illuminated seventh top lights can be found in [reference needed]. Figure 12 The seventh top light C1, seventh top light C2, seventh top light C3, seventh top light C4, seventh top light C5, seventh top light B1, seventh top light A5, seventh top light A2 and seventh top light A3.

[0286] It should be noted that the above Figure 12 In the example shown, if the number of times the user's hand is holding the book moves meets the preset conditions, the first dome light B2 can continue to be lit. The first dome light B2 can be lit when it is detected that the vehicle interior is in a dark environment, the user's hand is holding an open book, and the user's head is facing the book.

[0287] In another example, the lit seventh ceiling light could be any of the multiple ceiling lights other than the first ceiling light B2, corresponding to the user's location. It is easy to understand that the number of lit seventh ceiling lights can vary depending on the specific application scenario. This application does not limit this.

[0288] Second, the first object is electronic devices.

[0289] like Figure 13The diagram shown is a scenario illustrating a user's use of an electronic device, as provided in an embodiment of this application. See also... Figure 13 Assuming the electronic device is a tablet computer, for ease of explanation, Figure 13 The diagram uses a line drawing filled with diagonal lines to represent a tablet computer. Therefore, if the vehicle interior is detected to be in a dark environment, the user's hand is holding a tablet computer with its screen on, and the user's head is facing the tablet computer, at least one first overhead light (e.g., ...) will be activated. Figure 13 The first overhead light B2 allows the tablet computer to be positioned within the illumination range of the first overhead light B2.

[0290] In this example, it can be based on Figure 13 The first overhead light B2 is lit up at the location of the tablet computer.

[0291] In some embodiments, if the tablet computer is detected to be outside the illumination range of the first top light B2, the fifth top light can be turned on, so that the tablet computer is within the illumination range of both the fifth top light and the first top light B2.

[0292] In some embodiments, if the tablet computer is detected to be outside the illumination range of the first overhead light B2, the first overhead light B2 can be turned off after the fifth overhead light is turned on, thus removing the tablet computer from the illumination range of the first overhead light B2. In this case, the tablet computer can be within the illumination range of the fifth overhead light.

[0293] It is easy to understand that when there are many first ceiling lights, after turning on the fifth ceiling light, at least one sixth ceiling light among the multiple first ceiling lights can be turned off, so that the tablet computer is not within the illumination range of at least one sixth ceiling light. Based on this, the tablet computer can be within the illumination range of the fifth ceiling light and at least one first ceiling light other than the sixth ceiling light.

[0294] In some embodiments, if the user's EAR is detected to be less than or equal to a second threshold, at least one of the following overhead lights may be turned off: a first overhead light B2, a fifth overhead light, an overhead light corresponding to the user's eye, and an overhead light corresponding to the user's location.

[0295] In some embodiments, if the duration for which the user's EAR is detected to be less than or equal to the second threshold reaches a first preset duration, the first overhead light B2 may be turned off; and / or the fifth overhead light may be turned off; and / or the overhead light corresponding to the user's eyes may be turned off; and / or the overhead light corresponding to the user's location may be turned off.

[0296] It should be understood that, when a large number of first ceiling lights are lit, at least one of the multiple first ceiling lights can be turned off if the user's EAR is less than or equal to a second threshold or if the duration of the user's EAR being less than or equal to the second threshold reaches a first preset duration.

[0297] In some embodiments, if the user's movement information using the tablet computer meets preset conditions, the seventh ceiling light among the multiple ceiling lights can also be turned on so that the tablet computer can be within the illumination range of the seventh ceiling light and the first ceiling light B2.

[0298] The information regarding movement and preset conditions in the above embodiments can be understood by referring to the content in the scenario where the first object is paper-based documents, and will not be repeated here.

[0299] In some embodiments, for example, where the first object is an electronic device with a display screen, the illumination brightness of at least one first top light can also be adjusted based on the screen brightness of the electronic device if the difference between the screen brightness of the electronic device and the illumination brightness of at least one first top light is detected to be greater than or equal to a first threshold.

[0300] It should be understood that the specific value of the first threshold can be customized or pre-configured by the system.

[0301] As an example and not a limitation, the specific value of the first threshold can be greater than 0. When the value of the first threshold is greater than 0, if the screen brightness of the tablet computer is detected to be greater than the illumination brightness of at least one first overhead light, the illumination brightness of at least one first overhead light can be adjusted according to the screen brightness of the tablet computer.

[0302] Based on the above possible implementation methods, by balancing the screen brightness of the electronic device with the illumination brightness of at least one first overhead light, eye discomfort caused by using electronic devices in dark environments can be reduced, thereby alleviating visual burden, protecting eye health, and further improving the user experience.

[0303] based on Figure 12 The example shown allows for adjusting the brightness of the first overhead light B2 based on the screen brightness of the tablet computer if the difference between the screen brightness of the tablet computer and the illumination brightness of the first overhead light B2 is greater than or equal to a first threshold.

[0304] In one example, the screen brightness of the tablet computer and the illumination brightness of the first overhead light B2 can be directly obtained. The obtained screen brightness of the tablet computer and the illumination brightness of the first overhead light B2 are compared. When there is a large difference between the screen brightness of the tablet computer and the illumination brightness of the first overhead light B2 (i.e., the difference between the two is greater than or equal to a first threshold), the illumination brightness of the first overhead light B2 can be adjusted to balance the screen brightness of the tablet computer and the illumination brightness of the first overhead light B2. In other words, the screen brightness of the tablet computer and the illumination brightness of the first overhead light B2 are adapted to each other by adjusting the illumination brightness of the first overhead light B2.

[0305] In another example, the difference between the tablet's screen brightness and the illumination brightness of the first overhead light B2 can also be detected by acquiring an image of the user's face.

[0306] It should be understood that since the tablet screen can act as an active light source, when a user's face is facing the tablet, the brightness of the tablet screen will directly affect the reflective state of the face. Therefore, it is possible to acquire the user's facial image and determine the tablet screen brightness level by analyzing information such as the reflective intensity, distribution range, and color characteristics in the facial image.

[0307] Of course, the balance between the tablet's screen brightness and the illumination brightness of the first overhead light B2 can also be determined by comparing the brightness difference between the face and the background in the face image. In this case, the background brightness in the face image primarily comes from the first overhead light B2, while the face brightness in the face image primarily comes from the tablet's screen.

[0308] See Figure 14 When the brightness of the tablet's screen is higher than the illumination brightness of the first overhead light B2, the face is affected by the light from the tablet's screen. Figure 14 The image uses dotted shadow filling to represent the brightness of screen reflections on the face, resulting in high reflectivity in the face image. In this case, the brightness of the tablet screen and the brightness of the first top light B2 can be balanced by increasing the illumination brightness of the first top light B2. Figure 14 Similarly, the dotted shadow filling method is used to indicate that the brightness of the first top light B2 has been increased.

[0309] Third, the first object is a mirror.

[0310] like Figure 15 The diagram shown is a scenario illustrating a user's use of a mirror, as provided in an embodiment of this application. See also... Figure 15 It can illuminate the mirror when the vehicle interior is detected to be dark, the user has opened the mirror, and the user's head is facing the mirror. Figure 15 The first overhead lights A2, A3, B1, B2, C1, C2, and C3 are arranged such that the mirror can be located within the illumination range of the aforementioned multiple first overhead lights.

[0311] It should be understood that mirrors inside vehicles can be embedded in small tables (such as...). Figure 16 The mirror can be represented by a diamond-shaped filling method. When using the mirror, the user can first open the folding small table, and then open the embedded mirror on the small table. After the mirror is opened, the user can confirm that the mirror has been unfolded.

[0312] In one example, see Figure 16Alternatively, if the vehicle interior is detected to be dark, and the user has unfolded the small table with their head facing it, the first overhead light B2 can be activated to ensure the small table is within its illumination range. Then, if the vehicle interior is detected to be dark, and the user has unfolded the mirror with their head facing it, the first overhead light B2 can be activated. Figure 15 The first ceiling light A2, the first ceiling light A3, the first ceiling light B1, the first ceiling light C1, the first ceiling light C2, and the first ceiling light C3.

[0313] In some embodiments, if a shadowed area is detected on the user's face, at least one fourth top light among the multiple top lights may be turned on so that the shadowed area can be within the illumination range of the fourth top light.

[0314] It should be understood that the fourth dome light can be used to illuminate the shadowed areas of the user's face to uniformly distribute the light intensity on the user's face. As an example and not a limitation, algorithms such as luminance-chromatic sampling (YUV) modeling based on reflectivity analysis, dynamic light coding extended to liveness detection, and dual-source models fusing sensor data can be used to detect the shadowed areas of the user's face.

[0315] In practical applications, when the vehicle interior is detected to be dark, and the user has opened a mirror with their head facing it, the scenario can be identified as a makeup application. To eliminate facial shadows and avoid makeup mistakes caused by insufficient or uneven lighting (such as a fake-white finish, powdery residue, or cakey makeup), the light intensity on the user's face can be detected. If a shadowed area is detected, the corresponding fourth overhead light can be illuminated, placing the shadowed area within its illumination range. Based on this possible implementation, users no longer need to hold a fill light in makeup and similar scenarios, making it more convenient and further improving the user experience.

[0316] It is not difficult to understand, based on the aforementioned Figure 15 The example shown can illuminate at least one fourth top light as well as first top lights A2, A3, B1, B2, C1, C2, and C3, so that the user's face is within the illumination range of the fourth top light and at least one first top light. The multiple illuminated top lights can work together to provide lighting support for the user's makeup application, wherein the illuminated at least one fourth top light can play a role in uniformly distributing the light intensity on the user's face.

[0317] Based on the foregoing Figure 15In the example shown, assuming a shadow area is detected on the user's chin, and the illumination range of C4 among the multiple overhead lights can cover the shadow area, then the fourth overhead light C4 can be turned on when a shadow area is detected on the user's chin. In this way, the illumination of the fourth overhead light C4 can make the light intensity on the user's face more uniform.

[0318] It should be noted that in the above embodiments, since the position of the mirror is usually fixed, in practical application scenarios such as makeup, the user needs to constantly change their posture. Therefore, as the user's posture changes, the specific fourth ceiling light that is lit will also be different.

[0319] In some embodiments, the light source color of at least one first overhead light can also be adjusted in response to a first user operation.

[0320] For example, the light source color of at least one first top light may include warm light, neutral light, or cool light.

[0321] The first operation can be any triggering operation capable of changing the color of the light source of at least one first top light. For example, the first operation may include at least one of voice command, touch operation, gesture operation, and selection operation of first information.

[0322] It should be understood that voice commands can be used to directly indicate the color of the light source for at least one first overhead light. For example, see... Figure 17 Users can directly issue voice commands inside the vehicle, such as "Hey A, Hey A, set to warm light scene," and the vehicle can then change the light source color of at least one of the first dome lights to a warm light color based on the received voice command. Figure 17 The double-layered dashed circle indicates that the light source color of at least one first top light has been changed to a warm light color.

[0323] Touch operation can refer to a user directly selecting the light source color of at least one first dome light through physical buttons or other means on the in-vehicle device. In other words, the light source color of at least one first dome light can be directly adjusted in response to the user's selection of the light source color of at least one first dome light via touch operation.

[0324] Gesture control can be user-defined or pre-configured air gestures or touch gestures. In practical applications, the vehicle can adjust the light source color of at least one first dome light in response to the user's air gestures or touch gestures.

[0325] The first information, also known as reference information, can respond to a user's selection of the first information and adaptively adjust the light source color of at least one first overhead light based on the first information. The adjusted light source color of the at least one first overhead light can match the first information.

[0326] It's easy to understand that the primary information can include, but is not limited to, navigation information, scene information, time information, and weather information.

[0327] The navigation information may include current location information, waypoint location information, and / or destination location information.

[0328] In the above embodiments, the light source color of at least one first top light can be adjusted in response to the user's selection operation of at least one of the current location information, waypoint location information or destination information in the navigation information.

[0329] For example, suppose the user selects the destination information in the navigation information, and the destination location information is XX Park, then the light source color of at least one first overhead light can be changed to a warm light color.

[0330] In this way, when users apply makeup in their cars, they can switch at least one of the overhead lights to warm light mode to better simulate the natural lighting environment of a park. This method can ensure that the makeup effect (such as skin tone and shadow layering) completed by the user in the car is consistent with the actual effect after arriving at the park, avoiding makeup distortion caused by differences in ambient light.

[0331] Scene information can be used to indicate different scenarios. Examples include meeting scenarios (including indoor or outdoor meetings), photography scenarios, travel scenarios, dining scenarios, and so on. Specifically, the color of at least one first overhead light can be adjusted in response to a user's selection of different scene information.

[0332] Time information can represent different points in time during the day, such as morning, forenoon, noon, afternoon, and evening. Weather information can be used to indicate specific weather conditions, such as cloudy, sunny, rainy, snowy, or windy.

[0333] It is understood that the first information may also include other information, such as the user's emotional information or the color information of the light source that the user often uses in the makeup scene. The specific content of the first information is not limited in the embodiments of this application.

[0334] In some embodiments, the lighting effect information of at least one first ceiling light may be adjusted in response to a user's first operation. This lighting effect information may include information such as light color, light brightness, light rate, and lighting effects.

[0335] Understandably, light rate can be used to indicate the frequency of color changes in the overhead light. Lighting effects can adjust the overhead light to modes such as constant on, constant off, rainbow, multi-color cycle, single-point on, and single-point off. It should be understood that with technological advancements, lighting effect information can include more configuration information; this application embodiment does not limit the specific content included in the lighting effect information.

[0336] It should be noted that the above-described embodiment of adjusting the light source color and / or lighting effect information of at least one first top light in response to the user's first operation can be applied not only to application scenarios where the first object is a mirror, but also to other scenarios (such as the first object being paper documents, electronic devices, etc.).

[0337] In some embodiments, such as in an embodiment where the mirror can rotate or stay at any position according to the user's actual application needs, the fifth top light can also be turned on if it is detected that the mirror is not completely within the illumination range of the first top light B2, so that the mirror can be within the illumination range of the fifth top light and the first top light B2.

[0338] In some embodiments, the first ceiling light B2 can be turned off after the fifth ceiling light is turned on, so that the mirror can be within the illumination range of the fifth ceiling light, but not within the illumination range of the first ceiling light B2.

[0339] In some embodiments, if the user's EAR is detected to be less than or equal to a second threshold or the duration for which the user's EAR is less than or equal to the second threshold reaches a first preset duration, at least one of the following overhead lights may be turned off: the first overhead light B2, the fifth overhead light, the overhead light corresponding to the user's eyes, and the overhead light corresponding to the user's location.

[0340] In some embodiments, if the movement information of the user using the mirror meets preset conditions, the seventh ceiling light among the multiple ceiling lights can be turned on, so that the mirror can be within the illumination range of the seventh ceiling light and the first ceiling light B2.

[0341] Based on the above possible embodiments, detecting that the user's movement information using the mirror meets preset conditions may include: detecting that the user's movement amplitude using the mirror is greater than or equal to a preset amplitude, the length of the mirror's movement path is greater than or equal to a preset length, and / or the number of mirror movement positions is greater than or equal to a preset number, etc.

[0342] It should be understood that the specific details of the above-mentioned possible implementation methods can be found in the description of the aforementioned embodiment where the first object is paper-based material, and will not be repeated here.

[0343] Fourth, the first object is the sound pickup device.

[0344] See Figure 18This is a schematic diagram illustrating a user's use of a microphone device, provided as an embodiment of this application. See also... Figure 18 Taking a microphone as an example, when the vehicle interior is detected to be in a dark environment, the user's hand is holding the microphone and the user's head is facing the microphone, the first overhead light B2 can be turned on so that the microphone can be within the illumination range of the first overhead light B2.

[0345] It should be understood that in order to obtain a clear sound signal, users usually place the microphone near their mouth, which ensures that the user's head is facing the microphone.

[0346] In some examples, the user's head facing the microphone may include the user's eyes being focused on another device corresponding to the microphone.

[0347] In other words, the first overhead light B2 can be turned on when the vehicle interior is in a dark environment, the user's hand is holding a microphone, and the user's eyes are focused on other devices corresponding to the microphone.

[0348] For example, other devices could be devices with display capabilities, such as in-vehicle equipment or screens installed inside vehicles.

[0349] Based on the above Figure 18 As shown in the example, the microphone held by the user can also be in a pickup state, meaning the microphone has its pickup function activated. Specifically, if the vehicle interior is detected to be in a dark environment, the user is holding a microphone in a pickup state, and the user's head is facing the microphone in a pickup state, the first overhead light B2 can be turned on, so that the microphone in pickup state can be within the illumination range of the first overhead light B2.

[0350] In some embodiments, if the microphone is detected to be outside the illumination range of the first top light B2, the fifth top light may be turned on so that the microphone can be within the illumination range of both the fifth top light and the first top light B2.

[0351] In some embodiments, after the fifth top light is turned on, the first top light B2 can be turned off, so that the microphone is within the illumination range of the fifth top light but not within the illumination range of the first top light B2.

[0352] In some embodiments, if the user's EAR is detected to be less than or equal to a second threshold or the duration for which the user's EAR is less than or equal to the second threshold reaches a first preset duration, at least one of the following overhead lights may be turned off: the first overhead light B2, the fifth overhead light, the overhead light corresponding to the user's eyes, and the overhead light corresponding to the user's location.

[0353] In some embodiments, if the user's movement information using the microphone meets preset conditions, the seventh top light among the multiple top lights can be turned on, so that the microphone can be within the illumination range of the seventh top light and the first top light B2.

[0354] Based on the above possible embodiments, detecting that the user's microphone movement information meets preset conditions may further include: detecting that the user's microphone movement amplitude is greater than or equal to a preset amplitude, the microphone movement path length is greater than or equal to a preset length, and / or the number of microphone movement positions is greater than or equal to a preset number, etc.

[0355] It should be understood that the specific details of the above-mentioned possible implementation methods can be found in the description of the aforementioned embodiment where the first object is paper-based material, and will not be repeated here.

[0356] In application scenarios where the first object is a microphone, it can include one microphone or multiple microphones. For example, still taking a microphone as an example, see [link to relevant documentation]. Figure 19 The example shown may include two microphones.

[0357] In some embodiments, the sound pickup device may include a first sound pickup device and a second sound pickup device, so that according to the switching of duet roles in the lyrics of the currently playing song, the second top light corresponding to the first sound pickup device and / or the third top light corresponding to the second sound pickup device can be lit, so that the first sound pickup device can be within the illumination range of the second top light and the second sound pickup device can be within the illumination range of the third top light.

[0358] For example, see Figure 19 Users can set the currently playing song to duet mode. In duet mode, the currently playing song can be assigned as the first duet role (corresponding to...). Figure 19 A) and the second duet role (corresponding to Figure 19 In section B), the first duet singer can correspond to the first microphone, and the second duet singer can correspond to the second microphone; when the first duet singer's turn to sing arrives, the second overhead light corresponding to the first microphone can be turned on, for example, see [link to example]. Figure 19 The second overhead light, B2.

[0359] In the example above, when the time for the first duet singer to take over the song arrives, the time for the second duet singer to take over the song has not yet arrived, so the third top light E2 corresponding to the second pickup device can be turned off.

[0360] Subsequently, when the time comes for the second duet singer to take their turn, the third overhead light corresponding to the second microphone can be turned on, for example, see [link to previous text]. Figure 19 The third overhead light, E2.

[0361] In the example above, if the second duet singer's turn to sing has arrived and the first duet singer has already finished singing or the next turn to sing has not yet arrived, the second top light B2 can be turned off after the third top light is turned on. Based on this example, the first and second microphones can take turns lighting each other.

[0362] Of course, in another example, if the second duet singer's turn to sing has arrived and the first duet singer has finished singing or the next turn to sing has not yet arrived, the second top light B2 can continue to be lit after the third top light is lit.

[0363] In the example above, a certain lyric in the currently playing song can also be performed jointly by the first duet singer and the second duet singer, that is, by... Figure 19 A and B in the above are working together. Based on this, see [link to relevant documentation]. Figure 20 When the timing for the first and second duet singers to take turns singing arrives, the second top light B2 corresponding to the first pickup device and the third top light E2 corresponding to the second pickup device can be lit.

[0364] It's easy to understand that in other examples, there can be multiple second overhead lights. Similarly, there can be multiple third overhead lights.

[0365] In some embodiments, after the currently playing song has finished playing, the sound signals acquired by the first and second pickup devices can be evaluated based on the original audio information of the currently playing song to obtain an evaluation result.

[0366] It should be understood that the original audio information of the currently playing song can be compared and analyzed with the sound signal acquired by the first sound pickup device to obtain the evaluation result corresponding to the first sound pickup device; similarly, the original audio information of the currently playing song can be compared and analyzed with the sound signal acquired by the second sound pickup device to obtain the evaluation result corresponding to the second sound pickup device.

[0367] The original audio information of the currently playing song may include, but is not limited to, information such as pitch, rhythm, duration, and timbre. The evaluation results can be used to assess the singing performances of the users corresponding to the first and second duet roles, respectively.

[0368] For example, the evaluation results can be obtained by scoring or by using a grading system.

[0369] In one example, the evaluation results can be obtained using algorithms such as dynamic time warping (DTW), harmonic product spectrum (HPS), and mel-frequency cepstral coefficients (MFCC).

[0370] It's easy to understand that, in one example, in a scenario where the primary object is a microphone, the microphone can remain in a microphone state. For instance, after the microphone connects to the vehicle's in-vehicle equipment, its microphone function can be activated directly, and the activated microphone can remain in a microphone state.

[0371] In another example, the microphone can also activate its pickup function in response to a switch in the lyrics of the currently playing song.

[0372] For example, when the time comes for the first duet singer to take over the song, the pickup function of the first pickup device can be activated, and the second top light corresponding to the first pickup device can be lit up, so that the first pickup device can be within the illumination range of the second top light; when the time comes for the second duet singer to take over the song, the pickup function of the second pickup device can be activated, and the third top light corresponding to the second pickup device can be lit up, so that the second pickup device can be within the illumination range of the third top light.

[0373] It should be understood that the overhead light corresponding to the microphone can be illuminated based on its location. For example, the second overhead light can be illuminated based on the location of the first microphone; similarly, the third overhead light can be illuminated based on the location of the second microphone.

[0374] The system can also illuminate the corresponding ceiling light based on the activation of the microphone function. For example, the second ceiling light can be illuminated based on the activation of the microphone function of the first microphone. Similarly, the third ceiling light can be illuminated based on the activation of the microphone function of the second microphone.

[0375] It can also illuminate the corresponding ceiling light based on the acquisition of the sound signal. For example, when the first sound pickup device receives a sound signal, it illuminates the corresponding second ceiling light. Similarly, when the second sound pickup device receives a sound signal, it illuminates the corresponding third ceiling light.

[0376] In other embodiments, if the vehicle interior is detected to be in a dark environment, and the first user is using the first microphone with their head facing the first microphone, a second dome light corresponding to the first microphone may be illuminated. Subsequently, if the vehicle interior is detected to be in a dark environment, and a second user is using the second microphone with their head facing the second microphone, a third dome light corresponding to the second microphone may be illuminated.

[0377] Based on the lighting control method provided in this application, when the interior environment is dark, the user is using a first object (such as a paper document) and their head is continuously facing the first object, the first dome light in the corresponding area is automatically turned on. This eliminates the need for the user to manually operate physical buttons or touch screen menus, thus improving work efficiency. Furthermore, the first dome light in the corresponding position is only automatically turned on when all three conditions—dark environment, user using the first object, and the user's head facing the object—are met simultaneously. This accurately eliminates invalid scenarios, such as accidental light activation when the user is holding documents but not reading them. It effectively identifies the user's actual needs, reduces unnecessary lighting interference, ensures efficient matching of energy and function, and optimizes the user experience.

[0378] Furthermore, based on the above implementation method, at least one first overhead light corresponding to the first object can be precisely illuminated according to the user's actual application needs. In this way, when the user is engaged in activities such as reading inside the vehicle, their posture will no longer be restricted by the fixed position of the overhead light. This significantly improves the user's lighting experience in the vehicle cabin environment, creating a more comfortable, convenient, and personalized lighting environment.

[0379] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
