Description
Technical Field
[0001] This application relates to the field of unmanned vehicle control technology, specifically to a lighting control mechanism for visual supplementary lighting of unmanned vehicles and an unmanned vehicle. Background Technology
[0002] With the rapid development of autonomous driving technology, driverless vehicles (V2V) face extremely high demands on the accuracy and reliability of their perception of the surrounding environment. The visual perception system, as the core module for acquiring external environmental information, directly determines the driving safety and decision-making accuracy of V2V. Currently, V2V's visual perception mainly relies on onboard sensing devices such as front-facing cameras. However, these devices are easily affected by changes in ambient brightness in practical applications. For example, in low-light scenarios such as at night, in tunnels, or in rainy weather, insufficient ambient light can cause blurred details and reduced contrast in the images captured by the cameras, making it difficult to accurately identify key information such as pedestrians, obstacles, and traffic signs.
[0003] While existing vehicles are equipped with lighting systems, their initial design focused on human driving visibility. The width and range of illumination are not tailored to the perception requirements of autonomous vehicle vision systems. Although in some scenarios, if the width and distance of the high and low beams of traditional lights happen to match the visual system's requirements, they can temporarily meet basic supplementary lighting needs, the incompatibility is more pronounced in other scenarios. For example, the area near the ground in front of the vehicle is a blind spot for human drivers in traditional vehicles. The light path design of traditional low beams does not cover this area, resulting in this area being chronically without effective illumination. This area near the ground is precisely a critical perception area for autonomous vehicle vision systems, requiring clear identification of details such as ground protrusions, depressions, and small obstacles (such as stones and manhole covers); otherwise, it can easily lead to driving safety risks.
[0004] The shortcomings of the aforementioned existing technologies lead to a decrease in the visual perception accuracy of autonomous vehicles in complex lighting environments, which restricts their safe driving capabilities in all weather and all scenarios. Therefore, there is an urgent need for a lighting control mechanism that can achieve dynamic adaptation, collaborative control, precise supplementary lighting, and flexible adjustment functions to improve the stability and reliability of the autonomous vehicle's visual perception system. Utility Model Content
[0005] To overcome the shortcomings of the prior art, this application provides a lighting control mechanism for visual supplementary lighting of unmanned vehicles and an unmanned vehicle, specifically adopting the following technical solution: A lighting control mechanism for visual supplementary lighting of unmanned vehicles includes an on-board sensing mechanism, a supplementary lighting mechanism, and a vehicle control unit; The vehicle-mounted sensing mechanism includes at least one front-facing camera, which is mounted on the front of the unmanned vehicle. The vehicle-mounted sensing mechanism is used to collect brightness data of the area in front of the unmanned vehicle. The supplementary lighting mechanism includes at least one supplementary light, which is installed at the front of the unmanned vehicle and is used to provide supplementary lighting to the area in front of the unmanned vehicle. The vehicle control unit receives the brightness data from the on-board sensing mechanism and calculates the supplementary light signal, and controls the supplementary light mechanism to achieve supplementary lighting through the supplementary light signal.
[0006] Optionally, it also includes a lighting mechanism, which includes at least two headlights mounted at the front end of the driverless vehicle.
[0007] Optionally: The supplementary light adopts a ring or semi-ring light strip structure, and the supplementary light is arranged around the periphery of the headlight.
[0008] Optional: It also includes a control bus, in which the vehicle sensing mechanism, the supplementary lighting mechanism, the vehicle control unit and the lighting mechanism are connected in parallel to the control bus, and data is transmitted to each other through the control bus.
[0009] Optionally, a lighting control unit is included, which is connected in parallel to the control bus. The lighting mechanism and the supplementary lighting mechanism are respectively connected to the lighting control unit. The lighting control unit receives supplementary lighting signals from the vehicle control unit and performs lighting control on the lighting mechanism and the supplementary lighting mechanism.
[0010] Optional: Includes a remote control mechanism, which is connected in parallel to the control bus.

[0011] Optionally, the supplementary lighting mechanism includes multiple supplementary lights arranged in parallel at the front end of the unmanned vehicle, with each supplementary light independently illuminating a local area in front of the unmanned vehicle.
[0012] Optionally: The vehicle-mounted sensing mechanism includes at least one light sensor, which is installed at the front of the unmanned vehicle and is used to collect brightness data of the surrounding environment of the unmanned vehicle.
[0013] Optional: The lighting control unit adopts a power management unit.
[0014] In addition, this application also discloses an unmanned vehicle, which is equipped with a lighting control mechanism for visual supplementary lighting of the unmanned vehicle as described above.
[0015] The technical solution of this application achieves the following beneficial effects: The lighting control mechanism of this application collects brightness data of different areas in front of the autonomous vehicle in real time through the onboard sensing mechanism. Combined with the lighting requirements of the vision system for each area, the vehicle control unit calculates the appropriate supplementary lighting signal, and then the lighting control mechanism dynamically adjusts the intensity and range of the supplementary lighting mechanism. This mechanism can achieve precise supplementary lighting for the near-ground blind spot of the vehicle front that cannot be covered by traditional lamps; while for medium and long distance areas, it adjusts the supplementary lighting parameters according to the needs of the vision system. This avoids image blurring caused by insufficient supplementary lighting in low-brightness scenes, and prevents glare or energy waste caused by excessive supplementary lighting in strong light scenes. It significantly improves the image acquisition quality of the vision sensing system in all areas and complex lighting environments, and provides a reliable guarantee for the autonomous vehicle to accurately identify key information such as ground details, obstacles, and traffic signs.

[0022] The present application will now be further described with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application and should not be construed as limiting the scope of protection of the present application. It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present application.
[0023] Example 1: Specifically, in combination Figure 1As shown in the figure, this embodiment 1 discloses a lighting control mechanism for visual supplementary lighting of unmanned vehicles, including an on-board sensing mechanism, a supplementary lighting mechanism, and a vehicle control unit; it mainly solves the problem that traditional on-board lights cannot provide targeted supplementary lighting when the brightness of the unmanned vehicle's vision system in the area in front is insufficient. The lighting control mechanism of this embodiment 1 can realize the basic function of automatically adjusting supplementary lighting based on the ambient brightness, ensuring that the unmanned vehicle's vision system can clearly perceive the area in front, and providing basic lighting support for safe vehicle driving.
[0024] Specifically, the vehicle-mounted sensing mechanism described in Embodiment 1 includes at least one front-facing camera, which is installed at the front of the unmanned vehicle. Its core function is to collect brightness data of the area in front of the unmanned vehicle in real time, as a basis for determining whether supplemental lighting is needed.
[0025] In addition, the supplementary lighting mechanism described in Embodiment 1 is equipped with at least one supplementary light, which is also installed at the front of the unmanned vehicle. The activation and deactivation of the supplementary light are determined by subsequent control signals and are used to provide supplementary lighting when the brightness in the front area is insufficient.
[0026] Furthermore, in this embodiment 1, the vehicle control unit serves as the core control component. It receives brightness data of the forward area transmitted by the onboard sensing mechanism and analyzes and calculates the brightness data using a built-in algorithm. When it determines that the brightness is lower than the threshold required by the vision system, it generates a corresponding supplementary lighting signal and sends the signal to the supplementary lighting mechanism.
[0027] When the aforementioned lighting control mechanism is in operation, its specific workflow is as follows: First, the front-facing camera continuously collects image data of the area in front of the autonomous vehicle, and analyzes the image data to obtain the brightness data in front of the autonomous vehicle, and transmits the data to the vehicle control unit in real time.
[0028] After receiving the brightness data, the vehicle control unit will compare it with the preset brightness threshold for the vision system.
[0029] If the brightness data of a certain area is lower than the threshold, the vehicle control unit calculates the appropriate supplementary light intensity and supplementary light area, and generates a supplementary light signal; if the brightness data is higher than or equal to the threshold, no supplementary light signal is generated.
[0030] After receiving the supplementary lighting signal from the vehicle control unit, the supplementary lighting mechanism controls the corresponding supplementary lights to turn on according to the intensity and location specified by the signal, and provides supplementary lighting for the area in front of the unmanned vehicle; when the vehicle control unit determines that the brightness meets the standard and stops sending supplementary lighting signals, the supplementary lighting mechanism turns off the supplementary lights.
[0031] The aforementioned lighting control mechanism enables real-time monitoring and automatic supplemental lighting of the area in front of the autonomous vehicle, avoiding inaccurate recognition by the visual system due to insufficient brightness and providing a fundamental guarantee for environmental perception during autonomous vehicle operation. Furthermore, the various mechanisms have clear divisions of labor and work collaboratively, forming a complete closed loop for basic supplemental lighting control. Supplemental lighting adjustment can be completed without manual intervention, improving the automation level of autonomous vehicle operation. In addition, the supplemental lighting mechanism only activates when the brightness is insufficient, reducing unnecessary energy consumption and meeting the energy-saving operation requirements of autonomous vehicles.
[0032] Example 2: Combination Figure 2 As shown, the lighting control mechanism in this embodiment 2 retains the structural composition of the vehicle-mounted sensing mechanism, supplementary lighting mechanism, and vehicle control unit in embodiment 1. A lighting mechanism is further added, comprising at least two headlights installed at the front of the autonomous vehicle to provide basic road illumination for the area in front of the vehicle. Its operating state can be controlled independently according to the vehicle's driving needs, such as nighttime driving or driving on cloudy days, and can be controlled in conjunction with the supplementary lighting mechanism.
[0033] Based on the basic supplementary lighting function, the aforementioned control mechanism combines the illumination function of traditional headlights to achieve a dual lighting effect of "basic lighting + targeted supplementary lighting" in the area in front of the unmanned vehicle. This solves the problem of blind spots or insufficient brightness when traditional headlights work alone, and further enhances the visual perception ability of unmanned vehicles under different road conditions.
[0034] When the lighting control mechanism of Embodiment 2 above is working, its specific workflow is as follows: First, the front-facing camera of the vehicle's sensing mechanism simultaneously collects brightness data of the area in front. This data is used to determine whether supplemental lighting is needed, and also to provide a reference for adjusting the working status of the headlights in the lighting mechanism.
[0035] After receiving the brightness data, the vehicle control unit then performs control logic checks on the headlights and auxiliary lights respectively: If the overall ambient brightness is low, such as at night, the lighting mechanism will first activate the headlights to provide basic lighting. If the front camera still detects insufficient brightness in a local area, such as near the ground, after the headlights are activated, a supplementary light signal will be generated to activate the supplementary light for targeted supplementary lighting.
[0036] If the ambient brightness is at a moderate level, such as at dusk, you can turn on the supplementary lights individually to illuminate local dark areas, or turn on the headlights and supplementary lights at the same time to ensure that the overall brightness of the area in front meets the standard.
[0037] Finally, the lighting mechanism and the supplementary lighting mechanism receive control signals from the vehicle control unit and start or stop the corresponding lights according to the instructions to work together to complete the lighting task of the area in front.
[0038] The lighting control mechanism in Embodiment 2 combines basic illumination from the headlights with targeted supplemental lighting from the auxiliary lights, covering a wider area in front of the autonomous vehicle. In particular, it compensates for the blind spots of traditional headlights near the ground, allowing the vision system to clearly identify obstacles and road conditions in that area, significantly improving the driving safety of the autonomous vehicle. Furthermore, the working states of the headlights and auxiliary lights can be flexibly combined according to different ambient brightness levels, avoiding energy waste or insufficient lighting when only one light fixture is working, thus balancing lighting effect and energy saving requirements. This mechanism expands the applicable scenarios for autonomous vehicles, ensuring the normal operation of the vision system through dual lighting in various brightness environments such as nighttime, cloudy days, and tunnels, improving the vehicle's environmental adaptability.
[0039] Example 3: This embodiment 3 further optimizes the supplementary lighting mechanism of embodiment 2. First, it retains the structure of the vehicle sensing mechanism, vehicle control unit and lighting mechanism in embodiment 2, while the supplementary light adopts a ring or semi-ring light strip structure, which is arranged around the outer perimeter of the headlight to ensure that the illumination range of the supplementary light can be connected with the illumination range of the headlight, and focuses on covering the near-ground blind spot or edge area that the headlight cannot illuminate.
[0040] The lighting control mechanism in this embodiment 3 utilizes the surround lighting characteristics of the ring-shaped supplementary light, combined with the basic lighting of the headlight, to solve the problems of limited lighting range and poor coordination with the headlight in traditional supplementary lights. This achieves seamless connection between the supplementary lighting area and the headlight lighting area, improving the uniformity and coverage of lighting in the area in front of the unmanned vehicle.
[0041] When the lighting control mechanism of Embodiment 3 above is working, its specific workflow is as follows: First, the front-facing camera collects brightness data of the area in front, focusing on monitoring the brightness distribution within the headlight illumination range, especially the brightness data of the outer edge of the headlights and the area near the ground, and then transmits the data to the vehicle control unit.
[0042] The vehicle control unit then analyzes the data. If it finds an area with brightness below the threshold outside or near the ground in the headlight illumination area, it can directly generate a supplementary light signal to control the ring supplementary light to start, since the ring supplementary light surrounds the headlight.
[0043] After the ring-shaped auxiliary light is activated, its surround lighting can evenly illuminate the dark areas around the headlights, complementing the headlights' illumination area and making the overall lighting area in front of the driverless vehicle uniform in brightness with no obvious dark areas.
[0044] Finally, when the vehicle control unit detects that the overall brightness of the area ahead meets the standard, such as when entering a well-lit section of road, it first controls the ring auxiliary lights to turn off. If the ambient brightness continues to increase, it then controls the headlights to turn off to avoid energy waste.
[0045] The ring-shaped supplementary light in Embodiment 3 features a structural design that allows for closer integration with the headlights. The supplementary lighting area seamlessly connects with the headlight illumination area, eliminating potential lighting gaps between traditional supplementary lights and headlights. This improves the uniformity of illumination in the forward area, resulting in clearer and more accurate image information acquired by the vision system. Furthermore, the ring-shaped supplementary light structure provides a wider illumination range and more uniform light distribution. Compared to traditional single-point supplementary lights, it more effectively covers the headlight's blind spots, further enhancing the autonomous vehicle's vision system's perception of the forward environment. Moreover, the supplementary light's arrangement around the headlights eliminates the need for excessive additional installation space at the front of the autonomous vehicle, simplifying the lighting layout and reducing the complexity of the autonomous vehicle's front-end structural design.
[0046] Example 4: Combination Figure 3 As shown, the lighting control mechanism of this embodiment 4 is basically the same as that of embodiment 2, except that this embodiment 4 is equipped with a control bus, such as CAN ( Controller Area Network The system utilizes a control bus, where the vehicle-mounted sensing mechanism, supplementary lighting mechanism, vehicle control unit, and lighting mechanism are connected in parallel, enabling data transmission between them. This solves the problems of scattered data transmission and low collaborative control efficiency among the various mechanisms. By enabling parallel data transmission and centralized management of the vehicle-mounted sensing mechanism, supplementary lighting mechanism, vehicle control unit, and lighting mechanism through the control bus, it improves the collaborative response speed between the various mechanisms and ensures the real-time performance and accuracy of supplementary lighting and lighting control.
[0047] In the specific workflow of the lighting control mechanism in Embodiment 4: First, the front-facing camera of the vehicle sensing mechanism collects brightness data of the area in front and then transmits the data to the vehicle control unit in real time via the control bus. At the same time, the working status of the headlights of the lighting mechanism is also fed back to the vehicle control unit via the control bus.
[0048] The vehicle control unit receives brightness data from the on-board sensing mechanism and operating status data from the lighting mechanism via the control bus. After comprehensive analysis, it generates corresponding control signals, including headlight adjustment signals and auxiliary light signals.
[0049] The vehicle control unit sends control signals to the lighting mechanism and the supplementary lighting mechanism in parallel via the control bus, ensuring that both mechanisms can receive control commands simultaneously and avoiding asynchronous issues between lighting and supplementary lighting caused by data transmission delays.
[0050] After the lighting mechanism and the supplementary lighting mechanism adjust their working status according to the control signal, they feed back the latest working status to the vehicle control unit through the control bus, forming a data closed loop, which facilitates real-time monitoring and adjustment by the vehicle control unit.
[0051] The aforementioned control bus enables parallel data transmission between various mechanisms, significantly reducing data transmission latency. This ensures the vehicle control unit can acquire real-time status data from each mechanism and issue control commands promptly, improving the real-time performance of supplemental lighting and illumination control. This is particularly suitable for the rapid response requirements of autonomous vehicles traveling at high speeds to environmental changes. Furthermore, since each mechanism centrally manages data through the control bus, it avoids the problems of complex wiring and difficult fault diagnosis inherent in traditional distributed data transmission, reducing system maintenance difficulty and improving the overall system stability and reliability. In addition, the control bus-based architecture offers excellent scalability. If other lighting control-related mechanisms are added later, they can be directly connected to the control bus without significant modifications to the existing system structure, facilitating system function upgrades.
[0052] Example 5: Combination Figure 4 As shown, the lighting control mechanism in Embodiment 5, based on the structure of Embodiment 4, adds a lighting control unit, such as a power management unit (PMU), which is connected in parallel with the control bus. The lighting mechanism and the supplementary lighting mechanism are directly connected to the lighting control unit. The core function of the lighting control unit is to receive supplementary lighting and illumination commands from the vehicle control unit and to perform fine-grained lighting control on the lighting mechanism and the supplementary lighting mechanism. Through the newly added lighting control mechanism, the control functions of the lighting mechanism and the supplementary lighting mechanism are separated from the vehicle control unit, realizing a division of labor mode of "overall vehicle control + dedicated lighting control," improving the accuracy and flexibility of lighting control while reducing the computational load on the vehicle control unit.
[0053] The aforementioned lighting control unit can achieve precise control of the supplementary light and headlights, such as adjusting the intensity of the supplementary light according to different ambient brightness and controlling the timing of light activation to avoid interference from instantaneous strong light on the visual system, thereby improving the accuracy of lighting control and further optimizing the perception effect of the visual system.
[0054] Example 6: Combination Figure 5 As shown, in this embodiment 6, a remote control mechanism is added to the control bus based on embodiment 5. The staff can send lighting control commands to the remote control mechanism through a remote control terminal, such as a remote control platform or a handheld remote control. After receiving the commands, the remote control mechanism transmits them to the lighting control mechanism through the control bus, thereby realizing remote control of the supplementary lighting mechanism and the lighting mechanism.
[0055] Therefore, the light control mechanism of Embodiment 6 has two control modes: one is the automatic control mode, which has the same control process as that of Embodiment 5; the other is the remote control mode, in which staff can remotely send light control commands.
[0056] Specifically, in the remote control mode, the working process is as follows: When a situation that cannot be covered by the automatic control logic occurs, after the staff finds the problem through the remote control terminal, they send a specific light control command to the remote control mechanism.
[0057] After the remote control mechanism receives the command, it preferentially transmits the command to the light control mechanism via the control bus. Generally, the priority of a remote control command is higher than that of an automatic command from the vehicle control unit, so as to ensure rapid intervention in an emergency.
[0058] After the light control mechanism recognizes the remote control command, it suspends the execution of the automatic control command, and instead generates a specific light control signal according to the remote command to control the fill light mechanism and the lighting mechanism to adjust their working states.
[0059] The light control mechanism feeds back the execution result to the remote control mechanism via the control bus, and the remote control mechanism then feeds the result back to the remote control terminal. After the staff confirms that the light adjustment is in place, they can choose to keep the remote control mode or switch back to the automatic control mode according to the situation.
[0060] The above light control mechanism can provide emergency guarantee for the light system based on the remote control function. When a fault occurs in the automatic control link, the staff can quickly intervene through the remote control mechanism, so as to avoid the failure of the vision system of the unmanned vehicle caused by light problems, and improve the safety and reliability of the operation of the unmanned vehicle. At the same time, the flexibility of light control is increased. In special operation scenarios, the staff can remotely adjust the fill light angle, intensity and the working state of the headlamps according to actual requirements, meet personalized lighting requirements, and expand the application scenarios of the unmanned vehicle.
[0061] Embodiment 7: In combination with Figure 6 as shown, the light control mechanism of Embodiment 7 is improved for the on-board sensing mechanism based on the structure of Embodiment 1: in addition to the front camera, at least one additional light sensor can be equipped, which is installed at the front of the unmanned vehicle, and is used to collect the brightness data of different local areas in front more accurately and distinguish the brightness differences between different areas.
[0062] In addition, for the fill light mechanism, a plurality of fill lights can be configured, which are arranged side by side at the front end of the unmanned vehicle. Each fill light corresponds to a specific local area in front, such as the left near area, the right near area, the middle long-distance area, etc., and each fill light can independently receive a control signal via the control bus, so as to realize independent opening or closing and brightness adjustment.
[0063] The lighting control mechanism in Embodiment 7 operates as follows: First, the front-facing camera and light sensor of the vehicle's sensing mechanism work together to collect brightness data of different local areas in front of the autonomous vehicle (such as the left, middle, and right areas, and the near, middle, and far distance levels). The brightness data of each area is then transmitted to the vehicle control unit via the control bus.
[0064] The vehicle control unit then analyzes the brightness data of each local area one by one and compares it with the brightness threshold adapted to the vision system for each area: For example, if the brightness of the left near-ground area is detected to be lower than the threshold, only the supplementary lighting signal for the left near-ground supplementary light is generated; if the brightness of the right mid-distance area is also lower than the threshold, then the supplementary lighting signal for the right mid-distance supplementary light is generated, so as to achieve simultaneous supplementary lighting for multiple areas or individual supplementary lighting.
[0065] The vehicle control unit then sends independent supplementary lighting signals to the corresponding supplementary lights via the control bus. Each supplementary light is activated independently based on the received signal, illuminating the corresponding local area at a specified intensity.
[0066] During the supplemental lighting process, the onboard sensing mechanism continuously monitors the brightness changes of each local area. If the brightness of a certain area meets the standard, the vehicle control unit sends a stop supplemental lighting signal, and the corresponding supplemental light is turned off. The supplemental lights in other areas continue to work until the brightness of all areas meets the standard.
[0067] In this embodiment 7, multiple independent supplementary lights, light sensors, and a front-facing camera are combined to achieve precise supplementary lighting for different local areas in front, avoiding the energy waste or insufficient lighting in some areas caused by traditional single supplementary lights, thus improving the targeting and efficiency of supplementary lighting. Simultaneously, the vision system can more clearly identify detailed information in different local areas in front, reducing omissions caused by local dark areas and further improving the safety of the autonomous vehicle. Because each supplementary light is independently controlled, it can be flexibly adjusted according to the brightness changes in different areas, adapting to complex and ever-changing environments and enhancing the autonomous vehicle's adaptability to complex environments.
[0068] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
