Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle control, and in particular relates to a cabin lighting control system, method and vehicle. Background Art

[0002] The automotive industry is booming, with continuous advancements in electrification technology, rising car ownership, and improving people's quality of life. Against this backdrop, the functional positioning of the vehicle cockpit has undergone a significant shift, evolving from a simple driving and operating space to a third living space. This shift has driven cockpit design concepts that are more user-friendly, comfortable, personalized, emotional, and intelligent to become mainstream trends in the industry.

[0003] Driven by this trend, automotive cabin lighting design is experiencing new developments. On the one hand, cabin lighting arrangements are becoming increasingly diverse and dense, with a growing variety of lighting types, including ambient lighting and headlights, and the number of light sources continues to increase, aiming to create a richer, more unique, and more comfortable cabin environment for users. On the other hand, as users' demands for an intelligent cabin experience continue to rise, lighting control is also facing a higher level of intelligent demands. Users expect more flexible and diverse lighting control methods to meet their personalized needs in different scenarios.

[0004] Currently, the mainstream cabin lighting control technology in the industry uses a LIN line network to connect the various lighting sources within the vehicle. However, this technical solution has significant limitations. Specifically, the number of nodes that can be connected to a single LIN line is limited. For example, in actual applications, a LIN line is typically connected to the left and right body controllers, and the ambient light nodes are connected in series to this line. When the number of connected nodes reaches the upper limit of a single LIN line and additional lighting sources are required, a new LIN line must be opened and a master control device must be added to connect the new control nodes. Furthermore, the two master control devices must be connected via a CAN network to enable information exchange and control. This complex connection method not only significantly increases the complexity of the message control link and the difficulty of wiring layout, but also significantly increases the cost of the entire link system.

[0005] In summary, with the increase in the number of cabin lights and the improvement in their intelligence level, the existing cabin lighting control technology solutions based on LIN line networks can no longer meet actual needs in terms of accessibility and cost control, and the contradiction between the two is becoming increasingly prominent. Therefore, there is an urgent need to develop a new cabin lighting control system, method and related vehicles to effectively solve the above problems. The object of the present invention is to provide a cabin lighting control system, method and vehicle to solve the problems of limited access nodes and high cost of existing LIN line networks, while having good scalability.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: In a first aspect, a cabin lighting control system according to the present invention comprises: The vehicle computer comprises a cabin lighting main control module and a first wireless communication module, the cabin lighting main control module and the first wireless communication module being connected to each other and configured to generate and send lighting control instructions; Multiple light source devices are disposed in the cabin, each of the light source devices including a light fixture drive control module, and a second wireless communication module and a light fixture connected to the light fixture drive control module, the second wireless communication module being configured to wirelessly communicate with the vehicle computer to receive light control instructions, and the light fixture drive control module controlling the operating state of the light fixture according to the received light control instructions, wherein some of the light fixtures serve as ambient lights, and others as illumination lights; Among them, the vehicle computer and each light source device communicate wirelessly, the vehicle computer is the first master control node, and the light source device is the controlled node or forwarding node, so as to form an ad hoc network covering all controlled nodes in the cabin, and the light source device in the cabin is controlled by the vehicle computer.

[0007] Optionally, the vehicle computer further includes a third wireless communication module, which is connected to the cabin lighting master control module and is configured to establish a communication connection with a mobile terminal. When the mobile terminal is connected to the ad hoc network, the mobile terminal acts as a second master control node, enabling control of the system via a mobile terminal (e.g., a mobile phone).

[0008] Optionally, the light source device includes a fourth wireless communication module, which is connected to the lamp drive control module and is configured to establish a communication connection with a mobile terminal. When the mobile terminal is connected to the ad hoc network, the mobile terminal serves as a second master control node, enabling control of the system via a mobile terminal (e.g., a mobile phone).

[0009] Optionally, the vehicle computer includes a voice recognition module connected to the cabin lighting main control module. The voice recognition module is configured to receive and recognize voice commands. Based on the voice commands, the vehicle computer generates and sends corresponding lighting control commands to the lighting source devices. This means that the cabin lighting control system supports voice control of the cabin lighting source devices. Users can transmit lighting control requests via voice commands. After receiving and recognizing the voice commands, the vehicle computer generates corresponding lighting control commands and sends them to the corresponding lighting source devices, enabling voice control of the lighting and improving operational convenience.

[0010] Optionally, the vehicle computer includes an AI module connected to the cabin lighting master control module. This module is configured to automatically identify the wallpaper's theme color when the vehicle computer's wallpaper is switched. Based on this theme color, the vehicle computer generates corresponding lighting control instructions to control the corresponding light source device to produce ambient lighting effects that match the wallpaper's theme color. Specifically, the system enables wallpaper theme color-linked control. When the vehicle computer's wallpaper is switched, the AI ​​module automatically identifies the wallpaper's theme color and generates corresponding lighting control instructions based on this theme color. These instructions control the color, brightness, and other parameters of the corresponding light source device (here, an ambient light fixture), ensuring harmony and unity between the ambient lighting effects and the wallpaper's theme color, enhancing the overall visual quality of the cabin.

[0011] Optionally, the vehicle computer has a collection module, which is connected to the cabin lighting main control module and is used to collect steering information and acceleration signal changes; The vehicle computer generates corresponding lighting control instructions based on the steering information to control the corresponding light source device to generate a directional flowing light effect; Based on the changes in the acceleration signal, the vehicle computer generates corresponding lighting control instructions to control the corresponding light source device to produce a cool, breathing lighting effect at a preset frequency. This system enables intelligent, linked driving behavior control: When the driver operates the steering lever, the acquisition module detects the steering information and generates corresponding lighting control instructions, triggering the light source device (here, an ambient lighting strip) installed in the center console to produce a directional, flowing lighting effect. This lighting effect provides a cue for steering operation, enhancing driving safety and interactivity. If the driver accelerates suddenly, the acquisition module detects the changes in the acceleration signal and generates corresponding lighting control instructions to control the light source device (here, an ambient lighting strip) to switch to a cool, breathing lighting effect at a preset frequency, creating a tense and exciting lighting atmosphere.

[0012] Optionally, the vehicle computer includes an air conditioning status recognition module, which is connected to the cabin lighting master control module. The module is configured to identify air conditioning status signals. Based on these signals, the vehicle computer generates lighting control instructions to control corresponding light source devices to produce a breathing lighting effect. This allows the system to implement linked control of air conditioning functions: the vehicle computer recognizes the air conditioning status signals and generates lighting control instructions to control the light source devices (here, ambient lighting) to produce a breathing lighting effect throughout the vehicle, enriching the cabin's cool or warm ambiance.

[0013] Optionally, the vehicle computer has a pattern recognition module, which is connected to the cabin light main control module. The pattern recognition module is used to identify the vehicle mode. When the vehicle computer identifies that the vehicle mode is a nap mode or a camping bed mode, it generates a lighting control instruction to control the light color of the corresponding light source device to gradually change from high-frequency cold light to low-frequency warm light to simulate the change of sunset light, and control the corresponding light source device to perform a preset frequency breathing light and dark change lighting effect; that is, the system can realize the associated control of the in-vehicle rest function: when the vehicle computer identifies that the vehicle mode is a nap mode or the camping bed mode function is turned on, it generates a corresponding lighting control instruction, and the light color (here is the lighting lamp) is controlled to gradually change from high-frequency cold light to low-frequency warm light to simulate the change of sunset light, guiding the body into a pre-rest state; at the same time, the atmosphere lamps are dynamically controlled to produce a low-frequency breathing light and dark change effect, and some other redundant light sources are turned off to create a hazy and soft lighting atmosphere, caring for the cabin occupants to enter a rest state.

[0014] When the vehicle computer recognizes that the vehicle mode is home mode, it controls all lighting source devices to turn on, and at the same time controls the atmosphere light source devices to turn on the breathing light effect, creating a warm home atmosphere for the user.

[0015] In a second aspect, the present invention provides a cabin lighting control method, employing the cabin lighting control system of the present invention, wherein each light source device is controlled in three modes: single control, full control, and group control. Single control is independent control of a single light source device; full control is unified control of all light source devices; and group control is grouping multiple light source devices into different groups and centrally controlling the light sources within the group. The control method includes: The vehicle computer and the light source device establish an ad hoc network; The vehicle computer generates and sends a lighting control instruction to the corresponding light source device; The light source device generates corresponding lighting effects according to the light control instruction.

[0016] In a third aspect, a vehicle according to the present invention adopts the cabin lighting control system according to the present invention.

[0017] The present invention has the following beneficial effects: (1) The present invention adopts wireless communication and does not rely on the LIN line network, which solves the problem of limited access nodes of a single LIN line, reduces the difficulty of line layout and link cost, and adapts to the development needs of diversity and density of cabin lighting.

[0018] (2) The present invention supports multiple control modes such as single control, full control, group control, voice control, and mobile terminal wireless near-field control, meeting the different operating habits and needs of users and improving the flexibility and convenience of control.

[0019] (3) The present invention provides a variety of lighting effect controls for the atmosphere light, including flowing light effect, breathing light effect, etc., and each lighting effect can adjust multiple parameters, which can create a rich and diverse cabin atmosphere and meet personalized and emotional design needs.

[0020] (4) The present invention achieves the harmonious unity of wallpaper theme color and ambient light, as well as the associated control of ambient light with driving behavior and comfort function use, which improves the intelligence level of the cockpit and user experience, and enhances driving safety and interactivity.

[0021] In summary, the present invention solves the problems of limited access nodes and high cost in existing LIN line networks. At the same time, it has good scalability and can realize intelligent and diversified control of ambient lights and lighting lamps, meeting the development needs of diversified, dense and intelligent cabin lighting, and improving the user experience.

The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for the purpose of illustrating the present invention and are not intended to limit the scope of protection of the present invention.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner to facilitate understanding.

[0025] In the embodiments of the present application, at least one can also be described as one or more, and multiple can be two, three, four or more, which is not limited in this application.

[0026] like Figure 1 and Figure 2 As shown, in an embodiment of the present application, a cabin lighting control system includes a vehicle computer 1 and multiple light source devices 2. The vehicle computer 1 has a cabin lighting main control module 12 and a first wireless communication module 17. The cabin lighting main control module 12 and the first wireless communication module 17 are connected to generate and send lighting control instructions. Multiple light source devices 2 are arranged in the cabin. The light source device 2 includes a lamp drive control module 22, and a second wireless communication module 23 and a lamp 21 respectively connected to the lamp drive control module 22. The second wireless communication module 23 is used to wirelessly communicate with the vehicle computer 1 to receive light control instructions. The lamp drive control module 23 controls the working state of the lamp 21 according to the received light control instructions, wherein some of the lamps 21 are atmosphere lamps for providing atmosphere lighting, and other parts of the lamps 21 are lighting lamps for providing functional lighting. The vehicle computer 1 and each light source device 2 communicate wirelessly. The vehicle computer 1 is the first master control node, and the light source device 2 is the controlled node or forwarding node, so as to form an ad hoc network covering all controlled nodes in the cabin, and the light source device 2 in the cabin is controlled by the vehicle computer 1.

[0027] The cabin lighting control system in the embodiment of the present application does not require LIN line layout or the installation of an independent lighting controller, thereby saving system costs while retaining the scalability of the control network.

[0028] like Figure 1 As shown, in a possible embodiment, the vehicle computer 1 further has a third wireless communication module 16, which is connected to the cabin lighting main control module 12. The third wireless communication module 16 is used to establish a communication connection with the mobile terminal 3. When the mobile terminal 3 is connected to the self-organizing network, the mobile terminal 3 serves as the second master control node.

[0029] like Figure 1As shown, in a possible embodiment, the lamp source device 2 has a fourth wireless communication module 24, the fourth wireless communication module 24 is connected to the lamp drive control module 22, and the fourth wireless communication module 24 is used to establish a communication connection with the mobile terminal 3. When the mobile terminal 3 is connected to the self-organizing network, the mobile terminal 3 serves as the second master control node.

[0030] For example, the mobile terminal 3 is a mobile phone with wireless near-field communication capabilities, which can wirelessly connect to the vehicle computer 1 or the light source device 2 to control the light source device 2. Once the mobile phone is connected to the vehicle computer 1 or the light source device 2 via wireless communication, it can become a second master control node to control the light source device 2 in the cabin.

[0031] In one possible embodiment, the cabin lighting control system supports three control modes: single control, full control, and group control. Single control allows independent control of a single light source device 2; full control allows unified control of all light source devices 2; and group control divides multiple light source devices 2 into different groups for centralized control of the light source devices 2 within the group.

[0032] In a possible embodiment, for a lighting source device 2, the lighting control instructions include control adjustments such as switch, brightness, color temperature, and flashing frequency. The brightness and color temperature of the lighting lamp can be adjusted according to different scene requirements to meet the user's different requirements for functional lighting.

[0033] In one possible embodiment, for a light source device 2 of the ambient lighting type, the lighting control instructions include control and adjustment of on / off, brightness, light color, color temperature, flowing light effect, and breathing light effect. The flowing light effect can control the light color, brightness, direction, and flow speed to achieve a flowing light effect and create a different atmosphere; the breathing light effect can control the light color, interval frequency, and brightness to create a gradual effect of light breathing.

[0034] like Figure 1 As shown, in one possible embodiment, the vehicle computer 1 includes a voice recognition module 11, which is connected to a cabin lighting main control module 12. The voice recognition module 11 is used to receive and recognize voice commands. Based on the voice commands, the vehicle computer 1 generates and sends corresponding lighting control commands to the light source device 2. In other words, the cabin lighting control system supports voice control of the cabin lighting source device 2. Users can send lighting control requests via voice commands. After receiving and recognizing the voice commands, the vehicle computer 1 generates corresponding lighting control commands and sends them to the corresponding light source device 2, thus enabling voice control of the lights and improving operational convenience.

[0035] like Figure 1As shown, in a possible embodiment, the vehicle computer 1 has an AI module 18, which is connected to the cabin lighting main control module 12. The AI ​​module 18 is used to automatically identify the theme color of the wallpaper when switching the wallpaper of the vehicle computer 1. The vehicle computer 1 generates corresponding lighting control instructions according to the theme color to control the corresponding light source device 2 to generate an ambient light effect that is compatible with the wallpaper theme color.

[0036] That is, the system can realize the association control of wallpaper theme color: when switching the car wallpaper, the AI ​​module automatically identifies the corresponding theme color of the wallpaper, generates corresponding lighting control instructions according to the theme color, and controls the color, brightness and other parameters of the corresponding light source device 2 (here is the atmosphere lamp), so that the atmosphere lighting effect is harmonious and unified with the wallpaper theme color, thereby improving the overall visual effect of the cockpit.

[0037] like Figure 1 As shown, in one possible embodiment, the vehicle computer 1 includes a collection module 13 connected to the cabin lighting main control module 12. This collection module 13 is used to collect steering information and acceleration signal changes. Based on the steering information, the vehicle computer 1 generates corresponding lighting control instructions to control the corresponding light source device 2 to produce a directional flowing light effect. Based on the acceleration signal changes, the vehicle computer 1 generates corresponding lighting control instructions to control the corresponding light source device 2 to produce a cold-color breathing light effect with a preset frequency.

[0038] Specifically, the system enables intelligent, correlated driving behavior control: When the driver operates the steering lever, acquisition module 13 detects the steering information and generates corresponding lighting control commands, triggering light source device 2 (here, an ambient lighting strip) mounted on the center console to produce a directional, flowing light effect. This lighting effect indicates steering maneuvers, enhancing driving safety and interactivity. When the driver accelerates suddenly, acquisition module 13 detects changes in the acceleration signal and generates corresponding lighting control commands, switching light source device 2 (here, an ambient lighting strip) to a cool, breathing light effect with a specific frequency, creating a thrilling lighting atmosphere.

[0039] like Figure 1 As shown, in a possible embodiment, the vehicle computer 1 has an air conditioning status recognition module 14, which is connected to the cabin lighting main control module 12. The air conditioning status recognition module 14 is used to identify the air conditioning status signal. The vehicle computer 1 generates a lighting control instruction based on the air conditioning status signal to control the corresponding light source device 2 to produce a breathing light effect.

[0040] That is, the system can realize the associated control of the air-conditioning function: the vehicle computer recognizes the air-conditioning status signal and generates a lighting control instruction to control the light source device 2 (here is an atmosphere lamp) to realize the breathing lighting effect of the entire vehicle atmosphere lamp, enriching the creation of a cool or warm emotional atmosphere in the cabin.

[0041] like Figure 1As shown, in a possible embodiment, the vehicle computer 1 has a pattern recognition module 15, which is connected to the cabin lighting main control module 12. The pattern recognition module 15 is used to identify the vehicle mode. When the vehicle computer 1 identifies that the vehicle mode is a nap mode or a camping bed mode, it generates a lighting control instruction to control the light color of the corresponding light source device 2 to gradually change from high-frequency cold light to low-frequency warm light to simulate the change of sunset light, and control the corresponding light source device 2 to execute a preset frequency breathing light and dark change lighting effect.

[0042] That is, the system can realize the associated control of the rest function in the car: when the car computer recognizes that the vehicle mode is nap mode and the camping bed mode function is turned on, it generates corresponding lighting control instructions, and the light color (here is the lighting fixture) is controlled to gradually change from high-frequency cold light to low-frequency warm light to simulate the change of sunset light, guiding the body into a pre-rest state; at the same time, the atmosphere lamps are dynamically controlled to produce low-frequency breathing light and dark changes, and some other redundant light sources are turned off to create a hazy and soft lighting atmosphere, helping the cabin crew to enter a rest state.

[0043] When the car computer 1 recognizes that the vehicle mode is home mode, it controls all lighting source devices 2 to turn on, adjusts the brightness to 80%, and the color temperature to warm white; at the same time, it controls the atmosphere light source device 2 to turn on the breathing light effect, the light color is purple, the interval frequency is 2 seconds, and the brightness gradually changes from 50% to 100% and then gradually decreases, creating a warm home atmosphere for the user.

[0044] For example, the vehicle computer 1 utilizes an embedded processor with powerful processing power and wireless communication capabilities, such as a Qualcomm Snapdragon automotive processor. It integrates wireless communication modules such as Bluetooth, Wi-Fi, Zigbee, and UWDB for wireless connection with the light source device 2 and the mobile terminal 1. The AI ​​module 18 built into the vehicle computer 1 can identify the wallpaper theme color using an image recognition algorithm. For example, a convolutional neural network (CNN) can be used to analyze the wallpaper image and extract key color features as the theme color. The voice recognition module 11 built into the vehicle computer 1 identifies the voice control intention for the lights.

[0045] Exemplarily, the first wireless communication module 17 and the third wireless communication module 16 may be one wireless communication module or two different wireless communication modules.

[0046] Exemplarily, the lamp driver control module 22 utilizes a microcontroller (such as an STM32 series chip) as its core, combined with a driver circuit to control the lamp 21. For ambient lighting, such as RGB LED lamps, the lamp driver control module 22 uses PWM technology to control the brightness ratio of the red, green, and blue LEDs to adjust the light color. By controlling the frequency and duty cycle of the PWM signal, dynamic effects such as flowing and breathing light effects can be achieved. For lighting lamps, the lamp driver control module 22 adjusts the brightness and color temperature by adjusting the output voltage or current.

[0047] For example, the second wireless communication module 23 and the fourth wireless communication module 23 can be a single wireless communication module or two different wireless communication modules. The second wireless communication module 23 and the fourth wireless communication module 23 can use a low-power Bluetooth module, a Zigbee module, a Wi-Fi module, or a UWDB module, etc., and the appropriate wireless communication technology can be selected according to actual needs to ensure stable communication with the vehicle computer and the mobile terminal 3.

[0048] like Figure 3 As shown, for example, the ambient lighting fixtures 21 can adopt RGB LED light strips, LED reflector light strips, LED lamp beads or LED fiber optic light groups, etc., and are arranged in various positions in the cockpit, such as the front trunk area position 401, the instrument panel area position 402, the right front door panel area position 403, the right rear door panel area position 404, the third row right window lower area position 405, the trunk area position 406, the center console area position 407, the left front door panel area position 408, the left rear door area position 410, the third row left window lower area position 412, the right front seat top window area 413, the right rear seat top window area 414, the third row right seat top window area 419, the third row left seat top window area 415, the left rear seat top window area 416, the left front seat top window area 418, and the cockpit ceiling area 417. The lighting lamps 21 can be LED ceiling lights, reading lights, etc., and the appropriate lamp type and layout can be selected according to the lighting needs.

[0049] For example, mobile terminal 3 is a mobile phone, which can achieve wireless near-field control of light source device 2. The mobile phone provides a user-friendly interface, allowing users to select single control, full control, or group control modes and set lighting parameters, such as the color and lighting effect of atmosphere lamps 21 and the brightness and color temperature of lighting lamps 21. The mobile phone connects to the vehicle computer 1 or light source device 2 via Bluetooth or Wi-Fi to send lighting control commands.

[0050] like Figure 4As shown, in an embodiment of the present application, a cockpit lighting control method adopts a cockpit lighting control system as in the embodiment of the present application, and its control method includes: the vehicle computer 1 and the light source device 2 establish an ad hoc network; the vehicle computer 1 generates and sends a lighting control instruction to the corresponding light source device 2; the light source device 2 generates a corresponding lighting effect according to the lighting control instruction.

[0051] The following is a detailed description of the process of the cockpit lighting control method: Wireless network establishment: The vehicle computer 1 presets and imports the wireless communication address of each light source device 2. After power-on, the vehicle computer 1 and each light source device 2 form a communication network with an ad hoc topology structure through the first wireless communication module 17 and the second wireless communication module 23; the mobile terminal 3 establishes a connection with the vehicle computer 1 or the light source device 2 through wireless near-field communication.

[0052] Control Command Input: Users can input lighting control commands and freely group multiple light source devices 2 through the vehicle computer 1's user interface, mobile phone applications, or voice input. Input lighting control commands include single, full, and group control commands, as well as specific control parameters for different light source devices 2 (such as the on / off, brightness, and color temperature of lighting fixtures, and various lighting effect parameters for ambient lighting). The vehicle computer 1 detects various vehicle status signals (including but not limited to turn signal signals, air conditioning air volume signals, and air conditioning temperature signals) through the acquisition module 13, control state recognition module 13, and pattern recognition module 15. Based on the vehicle status signals, the vehicle computer 1 identifies the user's driving behavior and the activation of comfort functions, and generates related lighting control commands. The voice recognition module 11 identifies the in-vehicle lighting control intention and generates the corresponding lighting control command.

[0053] Command processing and sending: The vehicle computer 1 processes the received light control command, and sends the light control command to the second wireless communication module 23 of the corresponding light source device 2 through a wireless connection according to the command type and the target light source device 2.

[0054] Lighting adjustment: After receiving the lighting control instruction, the lamp driving control module 22 of the light source device 2 controls the working state of the lamp 21 according to the lighting control instruction, realizing operations such as light switching, color adjustment, brightness adjustment, color temperature adjustment, and lighting effect switching.

[0055] Real-time feedback and adjustment: The system monitors the working status and external input of the light source device 2 in real time, and adjusts the lighting control instructions in a timely manner according to the feedback information and new input instructions, thereby realizing dynamic real-time control of the lighting.

[0056] The following examples illustrate the application scenarios of the system: Wallpaper theme color associated control scenario: When the user switches the wallpaper on the car computer 1 to a landscape picture with blue as the main color, the AI ​​module 18 of the car computer 1 analyzes the pixel color of the wallpaper, identifies the RGB value of the theme color, generates a lighting control instruction and sends it to the corresponding light source device 2 (here is an atmosphere light source device). The atmosphere light source device 2 receives the lighting control instruction, and the lamp drive control module 22 parses the RGB value set in the lighting control instruction, and controls the light color, brightness and dynamic effect of the atmosphere light source device 2 according to the parameters corresponding to the lighting control instruction, so that the cabin atmosphere echoes the wallpaper theme.

[0057] Steering-triggered flowing light effect scenario: When the driver turns the steering lever to prepare to turn, the vehicle's steering sensor transmits a signal to the vehicle computer 1. After the acquisition module 13 detects the steering information, it generates a lighting control instruction and sends it to the target object (here, the through-ambience light strip installed on the dashboard (an atmosphere-type lighting source device)). After receiving the lighting control instruction, the target object controls the through-ambience light strip to generate a flowing light effect starting from the steering side and flowing outward. The light color is set to a striking yellow by default, and the flow speed is adjusted according to the vehicle speed or user settings. The lighting effect responds to driving behavior and enhances the user's driving experience.

[0058] Mobile phone wireless near-field control scenario: After entering the vehicle, the user establishes a Bluetooth connection with the vehicle computer 1 via their mobile phone and selects "Home Mode" on the mobile app. This "Home Mode" is preset to: all lights are on, dimmed to 80% brightness, and set to a warm white color temperature. The ambient lighting device activates a breathing effect, with a purple color and a 2-second interval, gradually increasing in brightness from 50% to 100% and then decreasing. After receiving the lighting control commands from the mobile phone, the vehicle computer 1 distributes them to the corresponding lighting device 2, enabling one-touch adjustment of the cabin lighting and creating a warm homecoming atmosphere.

[0059] When the car computer 1 plays music, the system can also achieve rhythmic lighting effects.

[0060] In summary, the cabin lighting control system and method provided in the embodiments of this application address the shortcomings of existing LIN line networks through wireless communication technology. They also integrate the lighting master controller into the vehicle computer and, optionally, the cabin domain controller. This enables diversified and intelligent control of ambient and illuminating lights, meeting the development trends and user needs of automotive cabin lighting, and possesses significant technical advantages and application value.
