Technical Field
[0001] This application relates to the field of vehicles, and more specifically, to methods, devices, vehicles and media for controlling vehicle lights in the field of vehicle lighting control. Background Technology
[0002] Current vehicle dynamic lighting warning systems generally suffer from limitations such as a single control dimension and insufficient scenario adaptability. Traditional solutions typically rely on only a few direct parameters, such as vehicle speed thresholds or brake switch signals, to trigger simple adjustments in light frequency, for example, increasing the hazard light frequency during emergency braking or activating special warning modes at high speeds. While this control logic based on isolated parameter judgments can provide basic warning functions in specific simple scenarios, it cannot achieve a fusion perception and deep interpretation of the vehicle's comprehensive dynamic state. It cannot effectively distinguish between different risk levels of motion states, such as driver-initiated lane changes, emergency obstacle avoidance, and vehicle loss of control, nor can it identify complex driving conditions such as understeer on low-friction surfaces or high-speed crosswind disturbances. This control strategy based on limited information not only restricts the release of the active safety performance of the lighting system in complex traffic environments but also fails to meet the evolving needs of vehicle-to-infrastructure (V2I) communication for refined and structured optical signal interaction in the era of autonomous driving. Summary of the Invention
[0003] This application provides a method, device, vehicle, and medium for controlling vehicle lights. The method dynamically generates control commands for the flashing frequency and brightness of the lights based on real-time information from multiple dimensions, including vehicle lateral acceleration, yaw rate, steering angle, and vehicle speed. This achieves adaptive matching between the warning light output and the vehicle's driving state. Thus, it breaks through the traditional adjustment mechanism that relies on a single vehicle speed signal. Through multi-source information fusion, the lighting system can respond more accurately to complex conditions such as emergency steering and high-speed lane changes, significantly improving the accuracy of warning signal context recognition and environmental adaptability.
[0004] In a first aspect, a method for controlling vehicle lights is provided, comprising: acquiring the light intensity of the environment in which the vehicle is located; when the light intensity is less than a preset light intensity threshold, in response to receiving a light-on signal, acquiring the vehicle speed, lateral acceleration, lateral angular velocity, and steering angle; determining the light flicker frequency enhancement coefficient and / or light brightness enhancement coefficient of the light fixture based on the lateral acceleration and lateral angular velocity; determining the light flicker frequency enhancement factor and / or light brightness enhancement factor of the light fixture based on the light flicker frequency enhancement factor and / or light brightness enhancement factor, vehicle speed, and steering angle; and controlling the light fixture to operate according to the light flicker frequency enhancement factor and / or light brightness enhancement factor.
[0005] This application dynamically generates control commands for the flashing frequency and brightness of the lights based on real-time information from multiple dimensions, including vehicle lateral acceleration, yaw rate, steering angle, and vehicle speed. This achieves adaptive matching between the warning light output and the vehicle's driving status. It breaks through the traditional adjustment mechanism that relies on a single vehicle speed signal. Through multi-source information fusion, the lighting system can respond more accurately to complex conditions such as emergency steering and high-speed lane changes, significantly improving the accuracy of warning signal context recognition and environmental adaptability.
[0006] According to one embodiment of this application, determining the light flicker frequency enhancement factor of a lamp based on the light flicker frequency enhancement coefficient, vehicle speed, and steering angle includes: calculating a first vehicle speed factor based on the vehicle speed and a first reference vehicle speed; calculating a first steering angle factor based on the steering angle and a first reference steering angle; calculating a light flicker frequency enhancement factor based on the first vehicle speed factor, the first steering angle factor, and the light flicker frequency enhancement coefficient; and integrating the light flicker frequency enhancement factor based on the lamp's on-time and the current time to obtain the light flicker frequency enhancement factor.
[0007] Thus, the first vehicle speed factor enables differentiated adjustment at different driving speeds, amplifying the warning intensity in high-speed scenarios and suppressing excessive interference in low-speed scenarios. Secondly, the first steering angle factor incorporates the driver's operating intention into the adjustment system, enabling the flashing characteristics of the lights to coordinate with the vehicle's steering behavior. Finally, the first vehicle speed factor and the first steering angle factor are used to dynamically weight the light flashing frequency enhancement coefficient to obtain the light flashing frequency enhancement factor. By performing time integration on the light flashing frequency enhancement factor, the change in flashing frequency presents a smooth transition characteristic, avoiding visual discomfort caused by sudden frequency changes, while strengthening the warning effect of continuous dangerous conditions.
[0008] According to one embodiment of this application, determining the light flicker frequency enhancement coefficient of a lamp based on lateral acceleration and lateral angular velocity includes: determining the light flicker frequency enhancement coefficient according to a first correspondence between lateral acceleration, lateral angular velocity and the light flicker frequency enhancement coefficient, wherein the first correspondence is used to characterize the correspondence between lateral acceleration-lateral angular velocity and the light flicker frequency enhancement coefficient.
[0009] This application establishes a mapping relationship between lateral acceleration and lateral angular velocity and the headlight flashing frequency enhancement coefficient, thereby achieving a direct quantitative conversion of vehicle dynamic urgency into headlight control parameters. This overcomes the limitations of relying on a single parameter criterion and significantly improves the accuracy and environmental adaptability of warning signals in complex driving scenarios.
[0010] According to one embodiment of this application, determining the light brightness enhancement factor of a lamp based on the light brightness enhancement coefficient, vehicle speed, and steering angle includes: calculating a second vehicle speed factor based on the vehicle speed and a second reference vehicle speed; calculating a second steering angle factor based on the steering angle and a second reference steering angle; calculating a light brightness enhancement factor based on the second vehicle speed factor, the second steering angle factor, and the light brightness enhancement coefficient; and integrating the light brightness enhancement factor based on the lamp's on time and the current time to obtain the light brightness enhancement factor.
[0011] Thus, the second vehicle speed factor enables differentiated adjustment at different driving speeds, amplifying the warning intensity in high-speed scenarios and suppressing excessive interference in low-speed scenarios. Secondly, the second steering angle factor incorporates the driver's operating intentions into the adjustment system, enabling the flashing characteristics of the lights to coordinate with the vehicle's steering behavior. Finally, the second vehicle speed factor and the second steering angle factor are used to dynamically weight the light brightness enhancement coefficient to obtain the light brightness enhancement factor. By performing time integration on the light brightness enhancement factor, the change in light brightness presents a smooth transition characteristic, avoiding visual discomfort caused by sudden brightness changes, while strengthening the warning effect of continuous dangerous conditions.
[0012] According to one embodiment of this application, determining the light brightness enhancement coefficient of a lamp based on lateral acceleration and lateral angular velocity includes: determining the light brightness enhancement coefficient according to a second correspondence between lateral acceleration, lateral angular velocity and the light brightness enhancement coefficient, wherein the second correspondence is used to characterize the correspondence between lateral acceleration-lateral angular velocity and the light brightness enhancement coefficient.
[0013] This application establishes a mapping relationship between lateral acceleration and lateral angular velocity and the headlight brightness enhancement coefficient, thereby achieving a direct quantitative conversion of vehicle dynamic urgency into headlight control parameters. This overcomes the limitations of relying on a single parameter criterion and significantly improves the accuracy and environmental adaptability of warning signals in complex driving scenarios.
[0014] According to one embodiment of this application, controlling the operation of a lamp based on a light flicker frequency enhancement factor includes: obtaining a reference light flicker frequency of the lamp; calculating a target light flicker frequency based on the light flicker frequency enhancement factor and the reference light flicker frequency; determining a pulse signal corresponding to the target light flicker frequency; and using the pulse signal to drive the lamp to operate at the target flicker frequency.
[0015] This application achieves dynamic and precise control of the flashing frequency of warning lights by fusing the enhancement factor of the flashing frequency with a reference frequency to form a target frequency and generating a corresponding pulse control signal. Thus, based on the fusion calculation of the reference frequency and enhancement factor, the frequency adjustment maintains a standardized benchmark while possessing dynamic adaptability, allowing the warning rhythm to accurately match driving scenarios of varying urgency. Secondly, by quantizing time into digital thresholds using a hardware counter, high-precision generation of the pulse signal cycle is achieved, ensuring the stability and anti-interference capability of the flashing frequency. Finally, the direct driving mechanism of the pulse signal to the power unit ensures that the light's on / off cycle strictly follows the target frequency command, not only improving the immediacy and recognizability of the warning signal but also avoiding visual discomfort through the smooth transition of frequency changes.
[0016] According to one embodiment of this application, controlling the operation of a luminaire based on a light brightness enhancement factor includes: obtaining a reference light brightness of the luminaire; calculating a target light brightness based on the light brightness enhancement factor and the reference light brightness; determining a driving current corresponding to the target light brightness; and using the driving current to drive the luminaire to operate at the target light brightness.
[0017] This application achieves dynamic and precise adjustment of warning light brightness by establishing a closed-loop conversion mechanism from brightness enhancement factor to target brightness value, and then to precise drive current. Firstly, enhancement calculation based on reference brightness ensures the standardization and controllability of brightness adjustment, avoiding arbitrariness in subjective settings. Secondly, a preset brightness-current mapping table ensures accurate matching of luminous flux and electrical parameters, guaranteeing consistency and reliability of brightness output under different operating conditions. Finally, a constant current drive method keeps the luminaire in a stable electrical state, improving luminous efficiency and lifespan while ensuring real-time synchronization of brightness response and dynamic commands. This allows the visual intensity of the warning lights to accurately match the actual risk level of the vehicle in complex driving scenarios.
[0018] Secondly, a vehicle lighting control device is provided, comprising: a first acquisition module for acquiring the light intensity of the environment in which the vehicle is located; a second acquisition module for acquiring the vehicle speed, lateral acceleration, lateral angular velocity, and steering angle in response to receiving a lighting activation signal when the light intensity is less than a preset light intensity threshold; a first determination module for determining the light flicker frequency enhancement coefficient and / or light brightness enhancement coefficient of the lighting fixture based on the lateral acceleration and lateral angular velocity; a second determination module for determining the light flicker frequency enhancement multiple and / or light brightness enhancement multiple of the lighting fixture based on the light flicker frequency enhancement coefficient and / or light brightness enhancement coefficient, vehicle speed, and steering angle; and a control module for controlling the operation of the lighting fixture according to the light flicker frequency enhancement multiple and / or light brightness enhancement multiple.

[0020] Fourthly, a vehicle is provided, including a memory, a processor, and a vehicle lighting control program stored in the memory and capable of running on the processor. When the processor executes the vehicle lighting control program, it implements the aforementioned vehicle lighting control method.
[0021] According to the vehicle lighting control method, device, vehicle, and medium of this application embodiment, the illuminance of the vehicle's environment is obtained; when the illuminance is less than a preset illuminance threshold, in response to receiving a lighting activation signal, the vehicle speed, lateral acceleration, lateral angular velocity, and steering angle are obtained; based on the lateral acceleration and lateral angular velocity, the lighting flicker frequency enhancement coefficient and / or lighting brightness enhancement coefficient of the lighting fixture are determined; based on the lighting flicker frequency enhancement coefficient and / or lighting brightness enhancement coefficient, vehicle speed, and steering angle, the lighting flicker frequency enhancement factor and / or lighting brightness enhancement factor of the lighting fixture are determined; and the lighting fixture is controlled to operate according to the lighting flicker frequency enhancement factor and / or lighting brightness enhancement factor. This application dynamically generates control commands for lighting flicker frequency and brightness based on multi-dimensional real-time information such as vehicle lateral acceleration, yaw rate, steering angle, and vehicle speed, achieving adaptive matching between warning light output and vehicle driving status. In this way, it breaks through the traditional adjustment mechanism that relies on a single vehicle speed signal. Through the fusion of multi-source information, the lighting system can respond more accurately to complex conditions such as emergency steering and high-speed lane changes, significantly improving the situational recognition accuracy and environmental adaptability of warning signals.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0024] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0025] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0026] The following describes in detail, with reference to the accompanying drawings, the vehicle lighting control method, device, vehicle, and medium according to embodiments of this application.
[0027] Figure 1 This is a flowchart of a vehicle lighting control method according to some embodiments of this application. (Refer to...) Figure 1 The vehicle lighting control method of this application embodiment may include the following steps: S110, obtains the light intensity of the environment in which the vehicle is located.
[0028] Specifically, one or more ambient light sensors can be installed in locations such as the inside of the windshield, above the dashboard, or on the roof module. Installing them on the inside of the windshield avoids interference from external dirt and is close to the human eye's visual perception area; installing them near the dashboard facilitates coordination with the vehicle's interior lighting system; and installing them on the roof provides unobstructed omnidirectional lighting information. Sensor types can be adapted to different cost and accuracy requirements, including fast-responding and low-cost photodiodes, photoresistors sensitive to changes in light intensity, or digital light sensors integrating analog-to-digital conversion with digital output and automatic range adjustment.
[0029] S120, when the light intensity is less than a preset light intensity threshold, responds to the received light-on signal by acquiring the vehicle's speed, lateral acceleration, lateral angular velocity, and steering angle. The preset light intensity threshold can be calibrated according to actual conditions and is not specifically limited here.
[0030] Specifically, after collecting the ambient light intensity of the vehicle's environment, the light intensity can be compared with a preset light intensity threshold to determine whether to change the flashing frequency and / or brightness of the lights when a light-on signal is received. For example, if the light intensity is greater than or equal to the preset light intensity threshold, it is determined that there is no need to change the flashing frequency and / or brightness of the lights; if the light intensity is less than the preset light intensity threshold, it is determined that the flashing frequency and / or brightness of the lights should be changed. The lights can be brake lights, hazard warning lights, turn signals, etc., without specific limitations.
[0031] Furthermore, by determining whether to change the flashing frequency and / or brightness of the lights, the vehicle's speed, lateral acceleration, lateral angular velocity, and steering angle are acquired. Vehicle speed acquisition can be achieved through two complementary methods: first, physical rotational speed measurement of the wheels, typically using Hall effect wheel speed sensors mounted on the wheel hub or driveshaft, calculating real-time wheel speed by detecting pulse signals from gears or magnetic encoders; second, using a multi-source data fusion algorithm, combining triaxial acceleration data from the onboard inertial measurement unit (IMU) with speed and position information from the Global Positioning System (GPS), and performing dynamic correction and estimation using algorithms such as Kalman filtering to improve the robustness and accuracy of vehicle speed measurement, especially maintaining reliable output even when wheel speed sensors are affected by factors such as slippage. Lateral acceleration and lateral angular velocity acquisition directly rely on a high-precision inertial measurement unit (IMU), whose core components include a triaxial microelectromechanical system (MEMS) accelerometer and a triaxial gyroscope. The accelerometer directly measures linear acceleration in the lateral, longitudinal, and vertical directions in the vehicle coordinate system, with lateral acceleration data directly used for lighting control. The gyroscope detects the vehicle's rotational angular velocity (yaw rate) around the vertical axis in real time, accurately reflecting the vehicle's steering and stability dynamics. Through the real-time data output of the IMU, the system can synchronously acquire multi-dimensional information about the vehicle's motion state.
[0032] Steering angle is acquired through angle sensing devices on the mechanical structure of the steering system. These typically employ non-contact, high-precision angle sensors (such as magnetic encoders or optical encoders) mounted on the steering column or rack to detect the absolute or relative rotation angle of the steering wheel in real time, transmitting analog or digital signals to the vehicle control system. This data not only reflects the driver's steering intentions but can also be used in conjunction with lateral dynamic parameters to determine the urgency of the steering action and the vehicle's response status, providing crucial input for lighting control.
[0033] It should be noted that there are no specific restrictions on the methods for collecting vehicle speed, lateral acceleration, lateral angular velocity, and steering angle.
[0034] S130, based on lateral acceleration and lateral angular velocity, determine the light flicker frequency enhancement coefficient and / or light brightness enhancement coefficient of the luminaire.
[0035] Specifically, lateral acceleration directly reflects the severity of steering or lane changing, while yaw rate characterizes the speed of vehicle rotation (such as fishtailing or loss of control); a higher value indicates a potential abrupt change in vehicle trajectory. Therefore, based on lateral acceleration and lateral angular velocity, the flashing frequency enhancement coefficient, brightness enhancement coefficient, or both of the headlights can be dynamically determined to map the vehicle's dynamic instability or urgency into the intensity of external visual warning signals. In other words, the greater the lateral acceleration and lateral angular velocity, the greater the flashing frequency enhancement coefficient and / or brightness enhancement coefficient; conversely, the smaller the lateral acceleration and lateral angular velocity, the smaller the flashing frequency enhancement coefficient and / or brightness enhancement coefficient.
[0036] For example, the lateral acceleration and lateral angular velocity can be input into the preset formula for calculating the light flicker frequency enhancement coefficient to calculate the light flicker frequency enhancement coefficient; similarly, the lateral acceleration and lateral angular velocity can also be input into the preset formula for calculating the light brightness enhancement coefficient to calculate the light brightness enhancement coefficient.
[0037] Specifically, by increasing the light brightness enhancement coefficient, the brake lights, turn signals, and hazard warning lights can emit a brighter light when turned on, highlighting the vehicle's emergency posture and position; by increasing the light flashing frequency enhancement coefficient, the turn signals and hazard warning lights can flash at a faster and more rapid frequency, thereby conveying an extremely urgent warning signal and turning signal.
[0038] S140, based on the light flicker frequency enhancement coefficient and / or light brightness enhancement coefficient, vehicle speed and steering angle, determine the light flicker frequency enhancement factor and / or light brightness enhancement factor of the lamp.
[0039] Specifically, after calculating the headlight flicker frequency enhancement coefficient, the headlight flicker frequency enhancement factor of the lamp can be determined based on the headlight flicker frequency enhancement coefficient, vehicle speed, and steering angle. For example, the headlight flicker frequency enhancement coefficient, vehicle speed, and steering angle can be input into a preset headlight flicker frequency enhancement factor calculation formula to calculate the headlight flicker frequency enhancement factor. After calculating the headlight brightness enhancement coefficient, the headlight brightness enhancement factor of the lamp can be determined based on the headlight brightness enhancement coefficient, vehicle speed, and steering angle. For example, the headlight brightness enhancement coefficient, vehicle speed, and steering angle can be input into a preset headlight brightness enhancement factor calculation formula to calculate the headlight brightness enhancement factor.
[0040] Vehicle speed is a key correction variable. At low speeds (such as in congested traffic), the enhancement factor is moderately suppressed to avoid excessive glare interference to surrounding vehicles. At high speeds (such as on expressways and highways), the enhancement factor is amplified to ensure that the warning signal remains clear and effective at greater distances and higher relative speeds. Meanwhile, steering angle provides a clear input of driving intent. A larger steering angle indicates that the driver is actively turning or making a U-turn, and the enhancement factor is amplified to strengthen the communication of the intent. A smaller steering angle moderately suppresses the enhancement factor to avoid excessive glare interference to surrounding vehicles.
[0041] S150 controls the operation of the luminaire based on the light flicker frequency enhancement factor and / or light brightness enhancement factor.
[0042] Specifically, when the light flicker frequency enhancement factor is calculated, the light fixture is controlled to operate based on the light flicker frequency enhancement factor; when the light brightness enhancement factor is calculated, the light fixture is controlled to operate based on the light brightness enhancement factor; when both the light flicker frequency enhancement factor and the light brightness enhancement factor are calculated, the light fixture is controlled to operate based on both factors.
[0043] Specifically, based on the final calculated enhancement factors for the flashing frequency and brightness, the lighting fixtures are precisely controlled using pulse width modulation (PWM) via the body control module (BCM) or a dedicated lighting drive unit. For example, for flashing frequency enhancement, the frequency of the periodic electrical signal driving the lighting fixture can be directly adjusted, increasing it from the standard frequency (e.g., 1-2 flashes per second) to the enhanced target frequency (e.g., 3-4 flashes per second or even higher), thereby accelerating the warning rhythm. For brightness enhancement, the luminous intensity of the light source (typically LED chips) can be increased by raising the duty cycle of the PWM signal or increasing the drive current, raising it from the standard brightness to the target brightness level.
[0044] This application dynamically generates control commands for the flashing frequency and brightness of the lights based on real-time information from multiple dimensions, including vehicle lateral acceleration, yaw rate, steering angle, and vehicle speed. This achieves adaptive matching between the warning light output and the vehicle's driving status. In doing so, it breaks through the traditional adjustment mechanism that relies on a single vehicle speed signal. Through multi-source information fusion, the lighting system can respond more accurately to complex conditions such as emergency steering and high-speed lane changes, significantly improving the accuracy of warning signal context recognition and environmental adaptability.
[0045] In some embodiments, determining the light flicker frequency enhancement factor of the lamp based on the light flicker frequency enhancement coefficient, vehicle speed, and steering angle includes: calculating a first vehicle speed factor based on the vehicle speed and a first reference vehicle speed; calculating a first steering angle factor based on the steering angle and a first reference steering angle; calculating a light flicker frequency enhancement factor based on the first vehicle speed factor, the first steering angle factor, and the light flicker frequency enhancement coefficient; and integrating the light flicker frequency enhancement factor based on the lamp's on-time and the current time to obtain the light flicker frequency enhancement factor. The first reference vehicle speed and the first reference steering angle can be calibrated according to actual conditions and are not specifically limited here.
[0046] Specifically, the headlight flashing frequency enhancement factor, vehicle speed, and steering angle can be input into the following headlight flashing frequency enhancement ratio calculation formula to obtain the headlight flashing frequency enhancement ratio: ; in, This indicates the factor by which the light flashing frequency is increased; Indicates vehicle speed; Indicates the steering angle; Indicates the light flicker frequency enhancement factor; Indicates when the light fixture is turned on; Indicates the current time; Indicates the first reference speed; Indicates the first reference steering angle; Indicates the first speed factor; Indicates the first steering angle factor; This represents the light flicker frequency enhancement factor.
[0047] Thus, the first vehicle speed factor enables differentiated adjustment at different driving speeds, amplifying the warning intensity in high-speed scenarios and suppressing excessive interference in low-speed scenarios. Secondly, the first steering angle factor incorporates the driver's operating intention into the adjustment system, enabling the flashing characteristics of the lights to coordinate with the vehicle's steering behavior. Finally, the first vehicle speed factor and the first steering angle factor are used to dynamically weight the light flashing frequency enhancement coefficient to obtain the light flashing frequency enhancement factor. By performing time integration on the light flashing frequency enhancement factor, the change in flashing frequency presents a smooth transition characteristic, avoiding visual discomfort caused by sudden frequency changes, while strengthening the warning effect of continuous dangerous conditions.
[0048] In some embodiments, determining the light flicker frequency enhancement coefficient of the luminaire based on lateral acceleration and lateral angular velocity includes: determining the light flicker frequency enhancement coefficient according to a first correspondence between lateral acceleration, lateral angular velocity and the light flicker frequency enhancement coefficient, wherein the first correspondence is used to characterize the correspondence between lateral acceleration-lateral angular velocity and the light flicker frequency enhancement coefficient.
[0049] Specifically, by establishing a pre-defined first correspondence between lateral acceleration, lateral angular velocity, and headlight flashing frequency enhancement coefficient, the real-time collected vehicle lateral acceleration and lateral angular velocity are mapped to specific headlight flashing frequency enhancement coefficients. This first correspondence, in the form of a function or mapping table, defines the headlight flashing frequency enhancement coefficient values corresponding to different combinations of lateral acceleration and lateral angular velocity, thereby quantifying the urgency level of vehicle dynamics into executable headlight control parameters. When a high lateral acceleration or yaw rate is detected, a higher headlight flashing frequency enhancement coefficient is automatically matched according to the first correspondence, causing the headlight flashing frequency to increase with the increase in the urgency level of vehicle dynamics, achieving real-time matching of warning intensity and driving status.
[0050] This application establishes a mapping relationship between lateral acceleration and lateral angular velocity and the headlight flashing frequency enhancement coefficient, thereby achieving a direct quantitative conversion of vehicle dynamic urgency into headlight control parameters. This overcomes the limitations of relying on a single parameter criterion and significantly improves the accuracy and environmental adaptability of warning signals in complex driving scenarios.
[0051] In some embodiments, determining the headlight brightness enhancement factor of the luminaire based on the headlight brightness enhancement coefficient, vehicle speed, and steering angle includes: calculating a second vehicle speed factor based on the vehicle speed and a second reference vehicle speed; calculating a second steering angle factor based on the steering angle and a second reference steering angle; calculating a headlight brightness enhancement factor based on the second vehicle speed factor, the second steering angle factor, and the headlight brightness enhancement coefficient; and integrating the headlight brightness enhancement factor based on the luminaire's on-time and the current time to obtain the headlight brightness enhancement factor. The second reference vehicle speed and the second reference steering angle can be calibrated according to actual conditions and are not specifically limited here.
[0052] Specifically, the headlight brightness enhancement factor, vehicle speed, and steering angle can be input into the following headlight brightness enhancement ratio calculation formula to obtain the headlight brightness enhancement ratio: ; in, Indicates the factor by which the light brightness is increased; Indicates vehicle speed; Indicates the steering angle; Indicates the light brightness enhancement factor; Indicates when the light fixture is turned on; Indicates the current time; Indicates the second reference speed; Indicates the second reference steering angle; Indicates the second speed factor; Indicates the second steering angle factor; This indicates the light brightness enhancement factor.
[0053] Thus, the second vehicle speed factor enables differentiated adjustment at different driving speeds, amplifying the warning intensity in high-speed scenarios and suppressing excessive interference in low-speed scenarios. Secondly, the second steering angle factor incorporates the driver's operating intentions into the adjustment system, enabling the flashing characteristics of the lights to coordinate with the vehicle's steering behavior. Finally, the second vehicle speed factor and the second steering angle factor are used to dynamically weight the light brightness enhancement coefficient to obtain the light brightness enhancement factor. By performing time integration on the light brightness enhancement factor, the change in light brightness presents a smooth transition characteristic, avoiding visual discomfort caused by sudden brightness changes, while strengthening the warning effect of continuous dangerous conditions.
[0054] In some embodiments, determining the light brightness enhancement coefficient of the luminaire based on lateral acceleration and lateral angular velocity includes: determining the light brightness enhancement coefficient according to a second correspondence between lateral acceleration, lateral angular velocity and the light brightness enhancement coefficient, wherein the second correspondence is used to characterize the correspondence between lateral acceleration-lateral angular velocity and the light brightness enhancement coefficient.
[0055] Specifically, by establishing a pre-defined second correspondence between lateral acceleration, lateral angular velocity, and headlight brightness enhancement coefficient, the real-time collected vehicle lateral acceleration and lateral angular velocity are mapped to specific headlight brightness enhancement coefficients. This second correspondence, in the form of a function or mapping table, defines the headlight brightness enhancement coefficient values corresponding to different combinations of lateral acceleration and lateral angular velocity, thereby quantifying the urgency of vehicle dynamics into executable headlight control parameters. When a high lateral acceleration or yaw rate is detected, a higher headlight brightness enhancement coefficient is automatically matched according to the second correspondence, causing the headlight flashing brightness to increase with the increase in the urgency of vehicle dynamics, achieving real-time matching of warning intensity and driving status.
[0056] This application establishes a mapping relationship between lateral acceleration and lateral angular velocity and the headlight brightness enhancement coefficient, thereby achieving a direct quantitative conversion of vehicle dynamic urgency into headlight control parameters. This overcomes the limitations of relying on a single parameter criterion and significantly improves the accuracy and environmental adaptability of warning signals in complex driving scenarios.
[0057] In some embodiments, controlling the operation of a luminaire based on a light flicker frequency enhancement factor includes: obtaining a reference light flicker frequency of the luminaire; calculating a target light flicker frequency based on the light flicker frequency enhancement factor and the reference light flicker frequency; determining a pulse signal corresponding to the target light flicker frequency; and using the pulse signal to drive the luminaire to operate at the target flicker frequency.
[0058] Specifically, firstly, using a preset reference light flashing frequency as a benchmark, the light flashing frequency enhancement factor is multiplied by the reference light flashing frequency or fused using a preset frequency mapping algorithm to calculate the target light flashing frequency suitable for the current driving conditions. Then, the target light flashing frequency is converted into an electrical signal cycle of a specific duration, and this cycle is quantified into a specific digital threshold by a hardware counter. When the drive circuit is working, the counter runs continuously and automatically switches between high and low levels when the digital threshold is reached, thereby generating a pulse signal whose cycle matches the target light flashing frequency. Finally, this pulse signal is transmitted to the lamp's power control unit, which, by sequentially turning the current flowing through the light source on and off, enables the lamp to complete an on / off cycle in rhythm synchronized with the target light flashing frequency, thus precisely driving the lamp to operate at the target flashing frequency.
[0059] This application achieves dynamic and precise control of the flashing frequency of warning lights by fusing the enhancement factor of the flashing frequency with a reference frequency to form a target frequency and generating a corresponding pulse control signal. Thus, based on the fusion calculation of the reference frequency and enhancement factor, the frequency adjustment maintains a standardized benchmark while possessing dynamic adaptability, allowing the warning rhythm to accurately match driving scenarios of varying urgency. Secondly, by quantizing time into digital thresholds using a hardware counter, high-precision generation of the pulse signal cycle is achieved, ensuring the stability and anti-interference capability of the flashing frequency. Finally, the direct driving mechanism of the pulse signal to the power unit ensures that the light's on / off cycle strictly follows the target frequency command, not only improving the immediacy and recognizability of the warning signal but also avoiding visual discomfort through the smooth transition of frequency changes.
[0060] In some embodiments, controlling the operation of the luminaire according to the light brightness enhancement factor includes: obtaining a reference light brightness of the luminaire; calculating a target light brightness based on the light brightness enhancement factor and the reference light brightness; determining the driving current corresponding to the target light brightness; and using the driving current to drive the luminaire to operate at the target light brightness.
[0061] Specifically, firstly, using a preset reference light brightness as a benchmark, the light brightness enhancement factor is multiplied by the reference light brightness or fused using a preset brightness mapping algorithm to calculate the target light brightness suitable for the current driving conditions. Then, based on the target light brightness, the drive current corresponding to the target light brightness is determined by looking up a preset relationship mapping table between light brightness and drive current. This preset relationship mapping table includes multiple light brightness levels and the drive current corresponding to each light brightness level. Finally, the drive current is output to the lamp through a constant current drive circuit, and the lamp automatically generates a luminous flux output that matches the drive current, thereby achieving operation at the target light brightness.
[0062] This application achieves dynamic and precise adjustment of warning light brightness by establishing a closed-loop conversion mechanism from brightness enhancement factor to target brightness value, and then to precise drive current. Firstly, enhancement calculation based on reference brightness ensures the standardization and controllability of brightness adjustment, avoiding arbitrariness in subjective settings. Secondly, a preset brightness-current mapping table ensures accurate matching of luminous flux and electrical parameters, guaranteeing consistency and reliability of brightness output under different operating conditions. Finally, a constant current drive method keeps the luminaire in a stable electrical state, improving luminous efficiency and lifespan while ensuring real-time synchronization of brightness response and dynamic commands. This allows the visual intensity of the warning lights to accurately match the actual risk level of the vehicle in complex driving scenarios.
[0063] In summary, this application dynamically generates control commands for the flashing frequency and brightness of lights based on real-time information from multiple dimensions, including vehicle lateral acceleration, yaw rate, steering angle, and vehicle speed. This achieves adaptive matching between warning light output and vehicle driving status. It breaks through the traditional adjustment mechanism that relies on a single vehicle speed signal. Through multi-source information fusion, the lighting system can respond more accurately to complex conditions such as emergency steering and high-speed lane changes, significantly improving the accuracy of warning signal context recognition and environmental adaptability. Especially in autonomous driving scenarios, it provides other road users with richer vehicle intent and status information. Through more accurate and timely dynamic warning signals, it effectively helps surrounding vehicles and pedestrians predict risks and react correctly, thereby enhancing overall road safety. The implementation is simple and reliable, requiring no large-scale hardware modifications. It can be directly implemented through software upgrades based on sensor data from existing systems such as ADB (Adaptive Driving Beam), AFS (Adaptive Front-lighting System), and ALS (Adaptive Lighting System). This significantly reduces deployment costs while ensuring system stability, demonstrating high practicality and market promotion value.
[0064] Corresponding to the above embodiments, this application also proposes a vehicle lighting control device.
[0065] Reference Figure 2 The vehicle lighting control device 200 includes: a first acquisition module 210, a second acquisition module 220, a first determination module 230, a second determination module 240, and a control module 250.
[0066] The system comprises the following modules: a first acquisition module 210 acquires the ambient light intensity of the vehicle's environment; a second acquisition module 220, in response to a lamp activation signal, acquires the vehicle's speed, lateral acceleration, lateral angular velocity, and steering angle when the ambient light intensity is less than a preset threshold; a first determination module 230 determines the lamp's flicker frequency enhancement coefficient and / or brightness enhancement coefficient based on the lateral acceleration and lateral angular velocity; a second determination module 240 determines the lamp's flicker frequency enhancement factor and / or brightness enhancement factor based on the flicker frequency enhancement coefficient and / or brightness enhancement factor, vehicle speed, and steering angle; and a control module 250 controls the lamp's operation according to the flicker frequency enhancement factor and / or brightness enhancement factor.
[0067] According to one embodiment of this application, the second determining module 240 is specifically used to: calculate a first vehicle speed factor based on the vehicle speed and a first reference vehicle speed; calculate a first steering angle factor based on the steering angle and a first reference steering angle; calculate a light flashing frequency enhancement factor based on the first vehicle speed factor, the first steering angle factor, and the light flashing frequency enhancement coefficient; and perform an integral operation on the light flashing frequency enhancement factor based on the light's on time and the current time to obtain the light flashing frequency enhancement multiple.
[0068] Thus, the first vehicle speed factor enables differentiated adjustment at different driving speeds, amplifying the warning intensity in high-speed scenarios and suppressing excessive interference in low-speed scenarios. Secondly, the first steering angle factor incorporates the driver's operating intention into the adjustment system, enabling the flashing characteristics of the lights to coordinate with the vehicle's steering behavior. Finally, the first vehicle speed factor and the first steering angle factor are used to dynamically weight the light flashing frequency enhancement coefficient to obtain the light flashing frequency enhancement factor. By performing time integration on the light flashing frequency enhancement factor, the change in flashing frequency presents a smooth transition characteristic, avoiding visual discomfort caused by sudden frequency changes, while strengthening the warning effect of continuous dangerous conditions.
[0069] According to one embodiment of this application, the first determining module 230 is specifically used to determine the light flicker frequency enhancement coefficient based on the lateral acceleration, lateral angular velocity and a first correspondence, wherein the first correspondence is used to characterize the correspondence between lateral acceleration-lateral angular velocity and the light flicker frequency enhancement coefficient.
[0070] This application establishes a mapping relationship between lateral acceleration and lateral angular velocity and the headlight flashing frequency enhancement coefficient, thereby achieving a direct quantitative conversion of vehicle dynamic urgency into headlight control parameters. This overcomes the limitations of relying on a single parameter criterion and significantly improves the accuracy and environmental adaptability of warning signals in complex driving scenarios.
[0071] According to one embodiment of this application, the second determining module 240 is specifically used to: calculate a second vehicle speed factor based on the vehicle speed and a second reference vehicle speed; calculate a second steering angle factor based on the steering angle and a second reference steering angle; calculate a light brightness enhancement factor based on the second vehicle speed factor, the second steering angle factor, and the light brightness enhancement coefficient; and perform an integral operation on the light brightness enhancement factor based on the lamp's on time and the current time to obtain the light brightness enhancement multiple.
[0072] Thus, the second vehicle speed factor enables differentiated adjustment at different driving speeds, amplifying the warning intensity in high-speed scenarios and suppressing excessive interference in low-speed scenarios. Secondly, the second steering angle factor incorporates the driver's operating intentions into the adjustment system, enabling the flashing characteristics of the lights to coordinate with the vehicle's steering behavior. Finally, the second vehicle speed factor and the second steering angle factor are used to dynamically weight the light brightness enhancement coefficient to obtain the light brightness enhancement factor. By performing time integration on the light brightness enhancement factor, the change in light brightness presents a smooth transition characteristic, avoiding visual discomfort caused by sudden brightness changes, while strengthening the warning effect of continuous dangerous conditions.
[0073] According to one embodiment of this application, the first determining module 230 is specifically used to determine the light brightness enhancement coefficient based on the lateral acceleration, lateral angular velocity and a second correspondence, wherein the second correspondence is used to characterize the correspondence between lateral acceleration-lateral angular velocity and the light brightness enhancement coefficient.
[0074] This application establishes a mapping relationship between lateral acceleration and lateral angular velocity and the headlight brightness enhancement coefficient, thereby achieving a direct quantitative conversion of vehicle dynamic urgency into headlight control parameters. This overcomes the limitations of relying on a single parameter criterion and significantly improves the accuracy and environmental adaptability of warning signals in complex driving scenarios.
[0075] According to one embodiment of this application, the control module 250 is specifically used to: obtain the reference light flicker frequency of the lamp; calculate the target light flicker frequency based on the light flicker frequency enhancement factor and the reference light flicker frequency; determine the pulse signal corresponding to the target light flicker frequency; and use the pulse signal to drive the lamp to work at the target flicker frequency.
[0076] This application achieves dynamic and precise control of the flashing frequency of warning lights by fusing the enhancement factor of the flashing frequency with a reference frequency to form a target frequency and generating a corresponding pulse control signal. Thus, based on the fusion calculation of the reference frequency and enhancement factor, the frequency adjustment maintains a standardized benchmark while possessing dynamic adaptability, allowing the warning rhythm to accurately match driving scenarios of varying urgency. Secondly, by quantizing time into digital thresholds using a hardware counter, high-precision generation of the pulse signal cycle is achieved, ensuring the stability and anti-interference capability of the flashing frequency. Finally, the direct driving mechanism of the pulse signal to the power unit ensures that the light's on / off cycle strictly follows the target frequency command, not only improving the immediacy and recognizability of the warning signal but also avoiding visual discomfort through the smooth transition of frequency changes.
[0077] According to one embodiment of this application, the control module 250 is specifically used to: obtain the reference light brightness of the lamp; calculate the target light brightness based on the light brightness enhancement factor and the reference light brightness; determine the driving current corresponding to the target light brightness; and use the driving current to drive the lamp to work at the target light brightness.
[0078] This application achieves dynamic and precise adjustment of warning light brightness by establishing a closed-loop conversion mechanism from brightness enhancement factor to target brightness value, and then to precise drive current. Firstly, enhancement calculation based on reference brightness ensures the standardization and controllability of brightness adjustment, avoiding arbitrariness in subjective settings. Secondly, a preset brightness-current mapping table ensures accurate matching of luminous flux and electrical parameters, guaranteeing consistency and reliability of brightness output under different operating conditions. Finally, a constant current drive method keeps the luminaire in a stable electrical state, improving luminous efficiency and lifespan while ensuring real-time synchronization of brightness response and dynamic commands. This allows the visual intensity of the warning lights to accurately match the actual risk level of the vehicle in complex driving scenarios.
