[0003] In addition to providing illumination, automotive lights nowadays also create different lighting effects by increasing the number or shape of the lights. This enhances the indication of the driver's steering and braking needs, allowing drivers of passing vehicles to quickly become aware and judge whether a vehicle is braking or about to turn based on the lighting effects, thus improving the driving experience.

[0004] However, car lights are unpredictable and often malfunction, making it impossible to promptly convey the driver's steering and braking needs. This makes it difficult for other drivers to accurately judge the vehicle's operating status.

[0051] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0052] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0053] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and corresponding operation portals are provided for users to choose to authorize or refuse.

[0054] With the continuous development of artificial intelligence technology, automobiles have gradually become intelligent. Currently, the intelligent functions of automobiles are mainly realized by five controllers, which control the movement of the vehicle through communication and data transmission between them. These five controllers include the powertrain domain controller, chassis domain controller, infotainment controller, body domain controller, and driver assistance controller.

[0055] The vehicle lighting system plays a crucial role in the operation of a car. It provides illumination for vehicles traveling at night and transmits information to other vehicles. For example, headlights illuminate the road at night, preventing accidents caused by poor visibility. When a car prepares to turn left, the left turn signal flashes when the turn signal is activated. Passing vehicles see the flashing turn signal through their windows and / or rearview mirrors, indicating that the car is about to turn left and allowing them to adjust their speed and position accordingly. Similarly, taillights flash when the car brakes, allowing other vehicles to adjust their speed and position and avoid rear-end collisions.

[0056] Drivers often experience fatigue or anxiety while driving, which is one of the factors contributing to accidents. To reduce the probability of accidents, increasing the number or brightness of headlights in the vehicle's lighting system can enhance the driver's alertness and sensitivity. This allows drivers, even when fatigued, to notice prominent lighting warnings by increasing the coverage area or brightness of the headlights and to take timely action based on the lighting warnings from nearby vehicles, thus ensuring driving safety.

[0057] However, as drivers adapt to increased headlight brightness and wider illumination range, relying on a single lighting effect for extended periods reduces driver sensitivity, failing to meet their needs and diminishing the driving experience. Furthermore, headlights have a limited lifespan, easily affected by human error or other factors, leading to performance degradation or damage. If headlights malfunction while driving, they cannot effectively provide nighttime illumination or promptly alert other drivers to the driver's status, increasing safety hazards.

[0058] This application, based on existing automotive lighting systems, connects the eyelid cover to the headlights to achieve turn signal functionality. It obtains the activation signal from the in-vehicle large screen and the function signal from the function controller via the vehicle domain controller. This function signal is then sent to the headlight controller and infotainment controller, enabling the headlight controller to control the gimbal motor module to drive the movement of the eyelid cover, providing a signal warning function. The mechanical movement of the eyelid cover, driven by the motor, transmits information, preventing delays in information transmission should the headlights malfunction. Furthermore, through communication between the infotainment controller, the display screen, and the vehicle's marker lights, a human-face-like lighting effect is achieved. This, combined with the headlight module's information transmission, enhances the driver's driving experience, further increasing driver interest and alertness, concentrating attention on driving, minimizing the probability of traffic accidents caused by driver fatigue, and ensuring driver safety.

[0059] Figure 1 A structural diagram of an automotive lighting control system provided in this application embodiment is shown below. Figure 1 As shown, the structure of the control system includes: a vehicle-mounted large screen 100, a body domain controller 200, a function controller 300, a headlight controller 400, a gimbal motor module 800, a headlight module 500, an infotainment controller 600, and a display module 700.

[0060] More specifically, the in-vehicle large screen 100 communicates with the body domain controller 200, and the body domain controller also communicates with the headlight controller 400 and the infotainment controller 600. The body domain controller is used to receive the start signal sent from the in-vehicle large screen and start the headlight controller and the infotainment controller according to the start signal. The function controller 300 communicates with the body domain controller 200, and the body domain controller is also used to receive the function signal sent from the function controller and send the function signal to the headlight controller and / or the infotainment controller.

[0061] Optionally, the headlight controller and the gimbal motor module communicate with each other. The headlight controller generates a first state signal based on the function signal and sends the first state signal to the gimbal motor module. The output of the gimbal motor module 800 is connected to the headlight module 500. The gimbal motor module receives the first state signal sent by the headlight controller and drives the headlight module to perform anthropomorphic control based on the first state signal. A schematic diagram of the headlight module is shown below. Figure 2 As shown, the headlight module structure is a simulation of the eyes of a human face.

[0062] Optionally, the infotainment controller and the display module 700 communicate via data. The infotainment controller generates a second state signal based on the function signal and performs anthropomorphic control of the display module based on the second state signal. A schematic diagram of the display module is shown below. Figure 3 As shown, the display module structure simulates the mouth and nose of a human face.

[0063] More specifically, Figure 4 This is a structural schematic diagram of an automotive lighting effect provided in an embodiment of this application, such as... Figure 4 As shown, the headlight module structure includes a headlight 510, an eyelid cover 520, and an eyeball 530. The display module structure includes a car logo light 710 and a display screen 720. Optionally, the headlight and eyelid cover are connected separately. The eyelid cover includes a vertical axis and a horizontal axis. The eyelid cover moves up and down along the vertical axis and rotates along the horizontal axis. The eyelid cover includes a left eyelid cover and a right eyelid cover. By simultaneously controlling the illumination of the eyelid cover, headlight, and eyeball in the headlight module, as well as the display screen and car logo light in the display module, dynamic lighting simulation of the human face structure is achieved. This further enhances the fun of the car lighting effects, increases driver viewing interest, reduces driving fatigue, and thus reduces the probability of fatigue-related accidents.

[0064] Optionally, such as Figure 5 The diagram shown is a structural diagram of an automotive lighting control system provided in an embodiment of this application. The system includes: a vehicle-mounted large screen 100, a body domain controller 200, a function controller 300, a headlight controller 400, a gimbal motor module 800, a headlight 510, a blind cover 520, an infotainment controller 600, automotive marker lights 710, and a display screen 720. The gimbal motor module 800 includes: an opening and closing motor 810, a rotating motor 820, a reduction gearbox 830, a vertical wheel 840, and a horizontal wheel 850.

[0065] The opening and closing motor obtains a first state signal by communicating with the headlight controller and controls the speed of the opening and closing motor according to the first state signal; the output end of the opening and closing motor is connected to the input end of the reduction gearbox, and the output end of the reduction gearbox is connected to one end of the vertical wheel to drive the vertical wheel to rotate; the other end of the vertical wheel is connected to the vertical axis of the eyelid cover, and the vertical wheel is used to drive the eyelid cover to move up and down along the vertical axis.

[0066] Optionally, the rotating motor obtains a first state signal by communicating with the headlight controller and controls the rotation speed of the rotating motor according to the first state signal; the output end of the rotating motor is connected to the input end of the gearbox; the output end of the gearbox is connected to the horizontal wheel to drive the horizontal wheel to rotate; the horizontal wheel is also connected to the horizontal axis of the eyelid cover to drive the eyelid cover to rotate along the horizontal axis.

[0067] In one possible embodiment, the driver sends a function signal to the vehicle domain controller via the function controller and a start signal to the vehicle domain controller via the in-vehicle large screen. The vehicle domain controller receives the function signal and the start signal, determines the driver's needs based on the function signal, and sends the function signal and the start signal to the headlight controller and / or infotainment controller to control the lighting effects of the headlight module and / or display module according to the driver's needs.

[0068] Optionally, when the driver's only need is lighting, the body domain controller sends a lighting activation signal to the headlight controller, which then turns on the headlights. When the driver needs to display the car's logo to oncoming vehicles, the body domain controller sends a logo activation signal to the infotainment controller, which then turns on the car's logo lights. The car's logo lights can be set to different brightness levels and colors.

[0069] Optionally, the control system also includes conventional turn signals or other vehicle lights, and the lighting control of the conventional turn signals or other vehicle lights is the same as the lighting control of the headlights in this application.

[0070] Optionally, when the driver needs to use the blindfold to indicate a function signal, the vehicle domain controller sends a start signal and a function signal to the headlight controller and the infotainment controller. The headlight controller turns on the headlights according to the start signal and generates a first status signal according to the function signal. The infotainment controller generates a second status signal according to the function signal. The first status signal includes a vertical movement status signal and a rotational movement status signal, and the second status signal includes a display status signal and a vehicle marker light status signal.

[0071] For example, when the headlight controller generates a first status signal and determines that it is a vertical movement status signal, the headlight controller sends the first status signal to the switching motor and starts the switching motor. The switching motor obtains the first status signal and generates the operating speed of the switching motor according to the first status signal. The switching motor rotates at this speed. After the speed of the switching motor is reduced by the connected reduction gearbox, it drives the vertical wheel to rotate, thereby controlling the eyelid cover to move up and down along the vertical axis of the eyelid cover connected to the vertical wheel.

[0072] The automotive lighting control system in this application directly controls the lighting effects of the headlights and vehicle marker lights through a headlight controller and an infotainment controller. At the same time, it increases the number of types of automotive lights that can be represented by mechanically driving the eyelid cover by connecting a motor to a reduction gearbox, and the rotation of the reduction gearbox to a wheel. This also avoids the inability to timely indicate the driver's driving status due to headlight damage, and improves the stability of expressing the driver's status through lighting effects.

[0073] Optionally, the function controller includes an unlock / lock controller, such as... Figure 6 The diagram shown is a structural diagram of an automotive lighting control system provided in an embodiment of this application. The system includes: an unlock / lock controller 310, a steering controller 320, a power controller 330, a vehicle-mounted large screen 100, a body domain controller 200, a headlight controller 400, a headlight 510, a blindfold cover 520, an infotainment controller 600, automotive marker lights 710, a display screen 720, an opening / closing motor 810, a rotating motor 820, a reduction gearbox 830, a vertical wheel 840, and a horizontal wheel 850.

[0074] More specifically, the unlocking / locking controller outputs an unlocking signal or a locking signal, and the body domain controller sends the unlocking signal or locking signal to the headlight controller. The headlight controller generates a first unlocking state signal or a first locking state signal based on the unlocking signal or locking signal, which is used to control the gimbal motor module to drive the eyelid cover to move up and down.

[0075] Optionally, the vehicle domain controller sends an unlock signal or a lock signal to the infotainment controller, which generates an unlock voice or a lock voice based on the unlock signal or lock signal, and controls the display screen to play the corresponding voice.

[0076] In one possible embodiment, the driver outputs an unlock signal to the vehicle domain controller via the lock / unlock controller and sends a start signal to the vehicle domain controller via the in-vehicle screen. The vehicle domain controller receives the unlock and start signals and sends them to the headlight controller. After receiving the start and unlock signals, the headlight controller starts the headlights according to the start signal and sends the unlock signal to the opening / closing motor. The opening / closing motor generates an unlock speed according to the unlock signal and operates at that unlock speed. After the speed is reduced by the connected reduction gearbox, it drives the vertical wheel to rotate, causing the eyelid cover to move up and down three times along the vertical axis of the eyelid cover connected to the vertical wheel.

[0077] In one possible embodiment, the driver outputs a locking signal to the vehicle domain controller via the locking / unlocking controller and sends a start signal to the vehicle domain controller via the in-vehicle screen. The vehicle domain controller receives the locking and start signals and sends them to the headlight controller. After receiving the start and locking signals, the headlight controller starts the headlights according to the start signal and sends the locking signal to the opening / closing motor. The opening / closing motor generates a locking speed according to the locking signal and operates at that locking speed. After the speed is reduced by the connected reduction gearbox, it drives the vertical wheel to rotate, causing the eyelid cover to move downward once along the vertical axis of the eyelid cover connected to the vertical wheel.

[0078] Optionally, the function controller may also include a steering controller, such as Figure 6 As shown, the steering controller outputs steering signals, which include left steering signals and right steering signals.

[0079] More specifically, the vehicle domain controller sends the steering signal to the headlight controller, which generates a first steering status signal based on the steering signal to control the gimbal motor module to drive the eyelid cover to rotate. The simulated left steering signal is achieved by rotating the left eyelid cover counterclockwise by 45° along the horizontal axis, and the simulated right steering signal is achieved by rotating the right eyelid cover clockwise by 45° along the horizontal axis.

[0080] Optionally, the eyelid cover is at an angle of 0° to the horizontal axis in the default state, as shown in Figure 7(a).

[0081] In one possible embodiment, the driver outputs a left turn signal to the vehicle domain controller via the steering controller and sends a start signal to the vehicle domain controller via the in-vehicle screen. The vehicle domain controller receives the left turn signal and the start signal and sends them to the headlight controller. After receiving the start signal and the left turn signal, the headlight controller starts the headlights according to the start signal and sends the left turn signal to the rotation motor. The rotation motor generates a left turn speed according to the left turn signal and operates at the left turn speed. After the speed is reduced by the connected reduction gearbox, it drives the horizontal wheel to deflect counterclockwise and connect to the left eyelid cover, so that the left eyelid cover rotates 45° clockwise along the horizontal axis of the eyelid cover connected to the horizontal wheel. The schematic diagram of the lighting effect of the left turn signal is shown in Figure 7(b).

[0082] In one possible embodiment, the driver outputs a right turn signal to the vehicle domain controller via the steering controller and sends a start signal to the vehicle domain controller via the in-vehicle screen. The vehicle domain controller receives the right turn signal and the start signal and sends them to the headlight controller. After receiving the start signal and the right turn signal, the headlight controller starts the headlights according to the start signal and sends the right turn signal to the rotation motor. The rotation motor generates a right turn speed according to the right turn signal and operates at the right turn speed. After the speed is reduced by the connected reduction gearbox, it drives the horizontal wheel to deflect to the right and connect to the right eyelid cover, so that the right eyelid cover rotates 45° to the right along the horizontal axis of the eyelid cover connected to the horizontal wheel. The lighting effect of the right turn signal is shown in Figure 7(c).

[0083] Optionally, the function controller may also include a battery controller, such as Figure 6 As shown, the battery controller outputs a battery signal, and the body domain controller sends the battery signal to the headlight controller and the infotainment controller respectively.

[0084] More specifically, the headlight controller generates a first battery signal based on the battery signal, which is used to control the gimbal motor module to drive the eyelid cover to rotate; the infotainment controller generates a second battery signal based on the battery signal, which is used to control the state of the display screen. The first battery signal includes a battery state value, and the second battery signal includes states corresponding to specific battery state values. These specific battery state values ​​include 0%, 20%, 40%, 60%, 80%, and 100%, corresponding to the states of being energetic, lively, playful, bored, and happy, respectively.

[0085] In one possible embodiment, when the vehicle's battery is low and needs charging, the driver outputs a battery signal to the body domain controller via the battery controller and sends a start signal to the body domain controller via the in-vehicle screen. The body domain controller receives the battery signal and the start signal and sends them to the headlight controller and the infotainment controller. Upon receiving the start signal and battery signal, the headlight controller activates the headlights based on the start signal and generates a first battery signal based on the battery signal, sending it to the rotary motor. The rotary motor generates a battery rotation speed based on the first battery signal and operates at that speed. After the speed is reduced by a connected reduction gearbox, it drives a horizontal wheel to deflect and engage with the eyelid covers. This causes the left eyelid cover to rotate counterclockwise along the horizontal axis connected to the horizontal wheel, and the right eyelid cover to rotate clockwise along the same horizontal axis. The rotation angle of the left and right eyelid covers ranges from 0° to 90°, and the angle increases linearly with the increase of the battery state value. At the same time, after the infotainment controller receives the start signal and the battery signal, it activates the car's indicator lights according to the start signal, generates a second battery signal according to the battery signal, and determines the state corresponding to the current special battery state value according to the second battery signal, and controls the state of the display screen according to the state.

[0086] For example: Figure 8 This is a schematic diagram of the lighting effect of a battery signal provided in an embodiment of this application, such as... Figure 8As shown, when the battery level is 0%, the left and right eyelid covers are parallel to the horizontal axis, with a rotation angle of 0°, and the display shows an "lively" characteristic; when the battery level is 20%, the left and right eyelid covers both rotate 18° along the horizontal axis, and the display shows an "lively" characteristic; when the battery level is 40%, the left and right eyelid covers both rotate 36° along the horizontal axis, and the display shows a "lively" characteristic; when the battery level is 60%, the left and right eyelid covers both rotate 54° along the horizontal axis, and the display shows a "playful" characteristic; when the battery level is 80%, the left and right eyelid covers both rotate 72° along the horizontal axis, and the display shows a "bored" characteristic; when the battery level is 100%, the left and right eyelid covers both rotate 90° along the horizontal axis, and the display shows a "happy" characteristic.

[0087] Optionally, such as Figure 6 As shown, the vehicle domain controller is also used to acquire a first feedback signal of the up-and-down movement of the eyelid cover, a second feedback signal of the rotational movement, and / or a third feedback signal of the display status, and to send the first feedback signal, the second feedback signal, and / or the third feedback signal to other control systems of the vehicle. The first feedback signal includes information on the up-and-down movement of the eyelid cover, the second feedback signal includes information on the rotational movement of the eyelid cover, and the third feedback signal includes display characteristic status signals and vehicle marker light characteristic status signals.

[0088] More specifically, after the eyelid cover moves up and down, it sends the up-and-down motion information to the vehicle domain controller; after the eyelid cover rotates, it sends the rotational motion information to the vehicle domain controller; after the display screen displays its characteristic status, it sends the display screen's characteristic status signal to the vehicle domain controller; and after the vehicle's marker lights display their characteristic status, they send the marker lights' characteristic status signal to the vehicle domain controller. The vehicle domain controller acquires the up-and-down motion information, rotational motion information, display screen characteristic status signal, and vehicle marker light characteristic status signal, and sends this information to other control systems of the vehicle for coordination and cooperation in vehicle operation.

[0089] Optionally, after the headlight controller activates the lights, it sends a lighting status signal to the vehicle domain controller. The mechanical movement of the headlight cover and the characteristic display of the display module represent the functional signals transmitted by the driver, enhancing the richness of the expression and increasing attention to the lights. This allows for focused driving and reduces the probability of accidents caused by distraction and failure to notice functional signals from nearby vehicles.

[0090] Optionally, users can also input custom information through the in-vehicle screen to customize the car's lighting mood style, such as... Figure 9The diagram shown is an interface schematic of a vehicle-mounted large screen provided in an embodiment of this application. The interface includes: a vehicle-mounted large screen switch 101, headlight module settings 110, display module settings 120, a first power unit 111, a first personalization unit 112, a second power unit 121, and a second personalization unit 122.
