Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a control method, device, electronic device, and storage medium for a lighting system. Background Technology

[0002] During driving, drivers need to concentrate for extended periods to assess various information while on the road. This state of mind easily leads to driver fatigue. Because a person sits in a fixed posture for long periods, performing only a few prescribed movements, and with the range of motion limited by certain conditions, some muscles are compressed, leading to muscle tension, poor blood circulation, and insufficient oxygen supply. This results in fatigue that is difficult to recover from and a feeling of being unable to perform at one's best. Driving in long tunnels further exacerbates this fatigue. Fatigue driving causes poor mental state, a sense of oppression while driving, slowed reaction time, weakened perception, and decreased awareness, leading to drowsiness, increased driving tension, speeding, and ultimately, traffic accidents.

[0003] In related technologies, drivers are mainly reminded through voice prompts, but auditory stimulation alone is insufficient to alleviate driver fatigue in long tunnels.

[0004] It is evident that the relevant technologies present a problem where drivers are prone to fatigue in extremely long tunnels. Summary of the Invention

[0005] In view of this, embodiments of this application provide a control method, device, electronic device, and storage medium for a lighting system to solve the problem that drivers in long tunnels are prone to fatigue driving in the prior art.

[0006] A first aspect of this application provides a method for controlling a lighting system, including:

[0007] The length of tunnels on the road traveled by the target vehicle is obtained through high-precision maps;

[0008] When the tunnel length exceeds the preset length, the vehicle's driving information is determined through a positioning system.

[0009] The real-time ambient light intensity is determined by a light sensor installed on the target vehicle.

[0010] Based on real-time ambient light intensity and driving information, control and adjust the luminous intensity of the lighting system inside the target vehicle;

[0011] The driving information includes at least one of the following: the target vehicle's speed, the distance the target vehicle travels inside the tunnel, and the distance between the target vehicle and the tunnel entrance before it enters the tunnel.

[0012] A second aspect of this application provides a control device for a lighting system, comprising:

[0013] The information acquisition module is used to obtain the length of tunnels on the road traveled by the target vehicle through a high-precision map;

[0014] The first determining module is used to determine the driving information of the target vehicle through the positioning system when the tunnel length is greater than the preset length.

[0015] The second determining module is used to determine the real-time ambient light intensity through a light sensor installed on the target vehicle;

[0016] The control module is used to control and adjust the luminous intensity of the lighting system inside the target vehicle based on real-time ambient light intensity and driving information.

[0017] The driving information includes at least one of the following: the target vehicle's speed, the distance the target vehicle travels inside the tunnel, and the distance between the target vehicle and the tunnel entrance before it enters the tunnel.

[0018] A third aspect of this application provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described method.

[0019] A fourth aspect of this application provides a readable storage medium storing a computer program that, when executed by a processor, implements the steps of the above-described method.

[0020] The beneficial effects of this application embodiment compared with the prior art are as follows: By acquiring tunnel information ahead of the road the vehicle is traveling on, understanding the road conditions and basic tunnel information, determining the vehicle's driving information after entering the tunnel, and judging the vehicle's position in the tunnel by the real-time distance traveled by the vehicle in the tunnel, the vehicle's speed, and the distance from the tunnel entrance and exit, this driving information and real-time monitoring are used to determine the current ambient light intensity. Combining the ambient light intensity with the real-time driving information, the luminous intensity of the vehicle's interior lights is controlled. This achieves the adjustment of the interior lighting system's luminous intensity based on the vehicle's position in the tunnel and the ambient light intensity when the vehicle is traveling in the tunnel. This allows the driver to maintain adaptation to ambient light when driving in long tunnels, preventing driver fatigue or drowsy driving caused by low light intensity, monotonous surroundings, and poor air quality in the tunnel. It extends the driver's adaptation time to ambient light intensity, improves the effect of alleviating driver fatigue, and solves the problem of drivers easily falling into a state of fatigue in long tunnels in related technologies.

[0029] The following describes in detail, with reference to the accompanying drawings, a control method and apparatus for a lighting system according to an embodiment of this application.

[0030] Figure 1 This is a flowchart illustrating the control method for a lighting system provided in this application. The execution entity of this method can be a controller or processor of the vehicle's interior lights; this embodiment uses a controller as an example for explanation. Figure 1 As shown, the control method of this lighting system includes:

[0031] Step 101: Obtain the tunnel lengths of the tunnels along the road traveled by the target vehicle using a high-precision map.

[0032] Specifically, the target vehicle can be a vehicle equipped with interior lights, including but not limited to sedans and vans.

[0033] High-precision maps can be obtained through positioning systems, LiDAR, or sensors, etc., without limitation here, and are used to determine the real-time location of target vehicles.

[0034] Tunnels refer to engineering structures buried in the ground or structures on the ground with a roof covering them, including but not limited to traffic tunnels and municipal tunnels.

[0035] The control process involves obtaining information about the length of the tunnel ahead on the road the vehicle is traveling on, which is used to determine whether the lighting system needs to be turned on.

[0036] Step 102: If the tunnel length is greater than the preset length, determine the driving information of the target vehicle through the positioning system.

[0037] Specifically, the preset length refers to the limited length for determining whether a tunnel is an extra-long tunnel. For example, if the preset length is 5 kilometers, the tunnel is determined to be an ordinary tunnel if the tunnel length is less than or equal to 5 kilometers, and to be an extra-long tunnel if the tunnel length is greater than 5 kilometers.

[0038] Positioning systems include, but are not limited to, satellite positioning systems or ultra-wideband positioning systems.

[0039] The driving information includes the vehicle's real-time distance traveled after entering the tunnel, the vehicle's real-time speed, and the distance from the tunnel entrance and exit. This driving information allows us to determine the vehicle's travel time within the tunnel, its location, and the time required to exit the tunnel.

[0040] During vehicle operation, the system determines whether there is a tunnel longer than a preset length ahead on the route. If such a tunnel exists, the system uses a positioning system to determine the vehicle's current driving information. This enables the positioning system to determine the vehicle's location when driving information is needed, reducing energy waste and improving the efficiency of obtaining driving information.

[0041] Step 103: Determine the real-time ambient light intensity using the light sensor installed on the target vehicle.

[0042] Specifically, light sensors include, but are not limited to, ambient light sensors, ultraviolet sensors, or sunlight sensors, which are used to detect the intensity of light in the surrounding environment and transmit the data.

[0043] Illuminance refers to the luminous flux of visible light received per unit area, used to indicate the intensity of light and the degree to which an object's surface area is illuminated. Ambient light intensity refers to the light intensity of the vehicle's current surrounding environment, and its light source can be natural light, artificial light, etc., which is not limited here. In the embodiments of this application, the illuminance data is acquired and transmitted by a light sensor for comparison with the illuminance of the lighting system.

[0044] Step 104: Based on the real-time ambient light intensity and driving information, control and adjust the luminous intensity of the lighting system inside the target vehicle.

[0045] Specifically, the lighting system refers to a lighting system installed inside the target vehicle that allows for adjustable light intensity. Its location can be anywhere within the driver's line of sight, including but not limited to above or to the side of the driver. The luminous intensity of the lighting system refers to the ability to control the brightness of the interior lighting system, increasing or decreasing its brightness according to control commands.

[0046] The interior lights can be installed anywhere that illuminates the driver, including but not limited to the area in front of or to the side of the driver. Types of interior lights include, but are not limited to, dome lights and ambient lights. By determining the ambient light intensity and driving information, the brightness of the interior lights can be controlled to gradually change, thereby improving the driver's adaptability to changes in light intensity and alleviating driver fatigue during long drives.

[0047] By setting the ambient light intensity to the maximum value achievable by the lighting system, the changes in the vehicle's interior lighting while driving in the tunnel are adjusted to alleviate driver fatigue, allow the driver to adapt to the external light in advance, extend the duration of the external light intensity in the tunnel, reduce driver fatigue, and improve driving safety.

[0048] The driving information includes at least one of the following: the target vehicle's speed, the distance the target vehicle travels inside the tunnel, and the distance between the target vehicle and the tunnel entrance before it enters the tunnel.

[0049] The distance traveled by the target vehicle inside the tunnel refers to the real-time distance traveled by the vehicle from the moment it enters the tunnel.

[0050] Driving speed refers to the speed of the vehicle during its journey.

[0051] The distance between the target vehicle and the tunnel entrance before the vehicle enters the tunnel is used to determine the time and distance required for the vehicle to reach the tunnel.

[0052] According to the technical solution provided in this application, the vehicle's driving position and tunnel information on the road are determined by high-precision maps and light sensors. Based on the tunnel information, relevant driving information of the vehicle within the tunnel can be obtained. Before entering the tunnel, the ambient light intensity is determined and recorded based on the driving information and real-time monitoring information. When the vehicle is driving in the tunnel, based on the obtained driving distance, speed, and distance between the vehicle and the tunnel entrance before entering the tunnel, the system is controlled to adjust the interior light intensity using the recorded ambient light intensity as the maximum value when the vehicle arrives at the tunnel or reaches different positions within the tunnel. This adjustment alleviates driver fatigue and extends the driver's adaptation time to external ambient light intensity. To reduce the "black hole" and "white hole" phenomena experienced by the driver when entering and exiting tunnels, the driver needs to gradually adapt to the light changes from the tunnel entrance to the tunnel interior and then to the tunnel exit. In this way, the driver can quickly adapt to the brightness changes outside and inside the tunnel, enhancing the driver's awareness, reducing the likelihood of driver fatigue, and improving driving safety.

[0053] In some embodiments, controlling and adjusting the luminous intensity of the lighting system inside the target vehicle based on real-time ambient light intensity and driving information includes:

[0054] The moment when the target vehicle enters the tunnel is determined based on the distance between the target vehicle and the tunnel entrance and the vehicle's speed before entering the tunnel.

[0055] When the current time arrives, if the real-time ambient light intensity is greater than zero, the first target luminous intensity corresponding to the real-time ambient light intensity is determined according to the pre-set correspondence between luminous intensity and light intensity.

[0056] Based on the correspondence between the current of the lighting system and the luminous intensity, the current of the lighting system is adjusted to the current corresponding to the first target luminous intensity, and the luminous intensity of the lighting system is controlled to be adjusted to the first target luminous intensity so that the light intensity inside the target vehicle is the same as the real-time ambient light intensity, and the timing is recorded by the vehicle timer.

[0057] When the on-board timer reaches the first countdown time, the light intensity of the control lighting system is reduced to zero.

[0058] Specifically, the time when the target vehicle enters the tunnel refers to the predicted time of the vehicle's entry into the tunnel, obtained by analyzing the vehicle's travel distance, speed, and distance from the tunnel entrance. This predicted time is marked as the start time of the vehicle's journey in the tunnel.

[0059] The pre-set correspondence between luminous intensity and illumination intensity refers to the relationship between ambient illumination intensity and vehicle interior light intensity under the premise of ensuring normal driver vision. Each ambient illumination intensity value has a corresponding light luminous intensity. For example, as an example, if the ambient illumination intensity is 60,000 lux, then according to the correspondence, the luminous intensity of the vehicle interior lights is 600 lux. Under the combined effect of this luminous intensity and the illumination inside the tunnel, the total illumination intensity inside the vehicle is the same as the ambient illumination intensity, which will not affect the driver's visual observation when entering the tunnel.

[0060] The first target luminous intensity refers to the luminous intensity corresponding to the real-time ambient light intensity when the vehicle enters the tunnel, and is used as the target value for adjusting the luminous intensity of the lights.

[0061] The relationship between the current supplied to the lighting system and the luminous intensity refers to the fact that the luminous intensity of the vehicle's lighting system is directly controlled by the current supplied. The luminous intensity of the lights can be directly controlled by controlling the current supplied. When the vehicle enters the tunnel, according to the relationship, the luminous intensity of the lights is adjusted to the first target luminous intensity by controlling the current supplied. Under the combined effect of this luminous intensity and the lighting inside the tunnel, the lighting intensity inside the target vehicle is the same as the real-time ambient lighting intensity.

[0062] In-vehicle timers include, but are not limited to, in-vehicle clocks or timing applications, used to measure the duration of the intensity of interior lighting.

[0063] The first timing period is used to measure the duration of the vehicle's headlight intensity when it enters the tunnel.

[0064] When the vehicle enters the tunnel, the headlight brightness is adjusted to the first target luminous intensity corresponding to the real-time ambient light intensity outside the tunnel, and then gradually weakened after the first timing period. This allows the driver's eyes to have a buffer time to adapt to the change in ambient light, avoiding damage to the driver's vision and improving driving safety. Since the headlights remain unchanged during the first timing period, the duration of the vehicle in the tunnel's lighting environment is shortened, reducing the possibility of driver fatigue caused by excessively long tunnels and monotonous surrounding environments.

[0065] When the vehicle enters the tunnel, the intensity of light received by the driver's eyes will change significantly. By combining the intensity of the interior lights with the light intensity inside the tunnel, the interior lights will continue to provide light to the driver instead of the ambient light intensity. The lights will then be turned off in stages to reduce the damage to the driver's eyes caused by sudden and drastic changes in light, which may even cause temporary visual impairment.

[0066] According to the technical solution provided in this application embodiment, the predicted time of the vehicle entering the tunnel is obtained by analyzing the vehicle's travel distance, speed, and distance to the tunnel entrance. When the vehicle's travel time reaches this predicted time, it is determined that this time is the time the vehicle enters the tunnel, which is also the start time of the vehicle's travel in the tunnel. At this time, the luminous intensity of the lighting system is controlled to adjust the interior light intensity to be the same as the ambient light intensity inside the tunnel, and then gradually weakens to zero after a first timing period, so that the interior light brightness achieves a bright-bright-dim effect, avoiding excessive stimulation to the driver's eyes caused by sudden brightening and dimming, which could lead to temporary visual impairment. When the vehicle enters the tunnel... When a driver enters a dimly lit tunnel from a well-lit open road, their eyes need time to adjust to the change in light and darkness. This adjustment causes the pupils to dilate. However, before the pupils have completed this physiological adjustment, the driver sees a blurry black scene, a phenomenon known as the "black hole effect." Under the influence of the black hole effect, the vehicle does not stop moving, creating a visual blind spot. This blind spot can easily lead to traffic accidents. By using gradually changing headlights, the driver's visual impact is reduced, and their vision is gradually guided to adapt to the weak light intensity inside the tunnel, within a certain level of visibility. Simultaneously, because the interior lights continue to provide illumination for a period after entering the tunnel, this method extends the driver's adaptation time to the current ambient light intensity, enhances driver concentration, reduces driver fatigue, and strengthens the driver's ability to stay alert while driving in the tunnel.

[0067] In some embodiments, controlling and adjusting the luminous intensity of the lighting system inside the target vehicle based on real-time ambient light intensity and driving information includes:

[0068] Determine the travel time of the target vehicle in the tunnel based on the travel distance and speed;

[0069] When the driving time reaches the first preset time, at the start time of each pre-divided time period, according to the pre-set correspondence between luminous intensity and light intensity, the second target luminous intensity corresponding to the real-time ambient light intensity is determined, and the luminous intensity of the lighting system is controlled to be adjusted to the second target luminous intensity so that the light intensity inside the target vehicle is the same as the real-time ambient light intensity, and the timing is recorded by the vehicle timer.

[0070] When the on-board timer reaches the second timing period, the light intensity is reduced to zero until the end of the time cycle is reached.

[0071] Specifically, the driving time of the target vehicle in the tunnel refers to the driving time experienced by the vehicle from the initial time of entering the tunnel, without driving in an environment outside the tunnel. This application embodiment uses the driver's driving time in the tunnel as the basic criterion for determining the driver's fatigue state; the driving time of the vehicle in the tunnel can be accurately determined by the distance and time traveled by the vehicle.

[0072] The pre-defined time interval can be 5 minutes, 10 minutes, or 1 hour, etc., and is not limited here. It is used as the time interval for adjusting the light intensity of the lighting system.

[0073] The second target luminous intensity can be 100 lux, 300 lux, or 500 lux, etc., without limitation. It is used to compensate for the luminous intensity of the light required by the real-time ambient light intensity after driving in the tunnel for a period of time, so as to ensure that the total luminous intensity inside the vehicle is the same as the real-time ambient light intensity.

[0074] The second timing period is used to measure the duration of the light intensity maintained when the vehicle travels in the tunnel for a pre-defined time period. It can be 5 minutes, 6 minutes, or 8 minutes, etc., and there is no limitation here.

[0075] For example, if the pre-defined time period is 30 minutes, as an example, after the vehicle has been driving for another 30 minutes after entering the tunnel, the real-time ambient light intensity is 2000 lux. The light intensity is controlled to reach 2000 lux, so that the light intensity inside the vehicle is the same as the real-time ambient light intensity. After the light intensity is maintained for 29 minutes, it is gradually adjusted to zero within 1 minute. This completes one light control process within a single pre-defined time period.

[0076] According to the technical solution provided in this application, during driving in long tunnels, the monotonous environment and dim lighting inside the tunnel can lead to driver fatigue, severely impacting driving safety. This application addresses this by determining that the driver is fatigued when the vehicle has been driving in the tunnel for a pre-defined time period. At this point, the vehicle's lighting system is adjusted to a second target light intensity, and this intensity is maintained for a second time. This method improves the accuracy of fatigue detection when the driver is fatigued, alleviates driver fatigue through changes in light intensity, prolongs the driver's adaptation time to the tunnel's ambient light intensity, and enhances the driver's ability to recover from fatigue.

[0077] In some embodiments, the driving information also includes the distance between the target vehicle and the tunnel exit after the vehicle enters the tunnel;

[0078] After determining the target vehicle's driving information through the positioning system, the process also includes:

[0079] When the distance between the target vehicle and the tunnel exit after entering the tunnel is detected to be greater than the preset distance, N pre-stored light colors are obtained, where N is greater than or equal to 2;

[0080] According to the preset light color change pattern, the ambient lights in the lighting system are controlled to switch and display the N light colors within a preset time period.

[0081] Specifically, the preset distance is used to indicate the distance a vehicle is about to exit the tunnel. When the distance between the vehicle and the tunnel exit is greater than the preset distance, it means that the vehicle will continue to travel in the tunnel for a period of time.

[0082] The N pre-stored light colors can include red, green, or blue, etc., without limitation, and are used as reserve colors for light color changes, where N is greater than or equal to 2.

[0083] The preset light color change pattern refers to the scheme for controlling light color changes that is pre-set in the vehicle's infotainment system. It can be an alternation of red and green or an alternation of red, yellow and blue, etc., and is not limited here.

[0084] Ambient lighting refers to lighting devices in a vehicle that can change color to match the desired driving atmosphere.

[0085] The preset time period refers to the duration during which the light color changes according to a preset light color change pattern.

[0086] According to the technical solution provided in this application, when the vehicle is still some distance from the tunnel exit, the driver's fatigue can be alleviated by changing the color of the interior lights. The light colors are based on a pre-stored color scheme, for example, with a preset distance of 3 kilometers and a preset time period of 2 minutes. As an example, when the vehicle is 5 kilometers from the tunnel exit, the interior lights are controlled to alternate between red and green for 2 minutes. This achieves the goal of providing appropriate visual stimulation to the driver in a long tunnel by changing the light colors, alleviating driver fatigue, and enhancing driving safety.

[0087] In some embodiments, before controlling and adjusting the luminous intensity of the lighting system inside the target vehicle based on real-time ambient light intensity and driving information, the method further includes:

[0088] Obtain passenger information inside the target vehicle through an occupant monitoring system;

[0089] Determine the lighting status at the corresponding location based on passenger information;

[0090] If the passenger information indicates that the passenger is not asleep, the corresponding light at that location will be switched to a coordinated adjustment state, which will be used to mark that the corresponding light will be adjusted together according to subsequent control commands.

[0091] If the passenger information indicates that the passenger is asleep, the corresponding light at that location will be set to a "no adjustment" state to mark that the light at that location cannot be adjusted during the current trip.

[0092] If there are no passengers at the location indicated by the passenger information, the corresponding light at that location will be set to a state where adjustment is prohibited.

[0093] Specifically, the occupant monitoring system can be an occupant behavior monitoring system, a passenger counting system, or a passenger abnormal behavior monitoring system, etc., without limitation here, and is used to monitor and report the number of occupants in the vehicle and their corresponding passenger location information.

[0094] Lighting status refers to the lighting control scheme corresponding to different occupant states under the premise of the aforementioned lighting system adjustment process. This includes, but is not limited to, coordinated adjustment status, which indicates that the lighting and the lighting system adjustment process are under unified control and can be changed according to the corresponding control information. Adjustment prohibited status indicates that the lighting equipment in this state will not be adjusted and will remain unchanged.

[0095] Passenger information includes, but is not limited to, passenger location information, facial image information, or behavioral information, which is used to determine the passenger status. Passenger status includes any one of the following: sleeping state, non-sleeping state, or no passenger status.

[0096] According to the technical solution provided in this application embodiment, by acquiring passenger information and lighting status information, the lighting at the corresponding passenger positions is controlled to adjust the status: for passengers not asleep, the lighting at their positions is adjusted to a coordinated adjustment state, which can be adjusted together with the lighting of the entire vehicle; for passengers asleep, the lighting at their positions is adjusted to a prohibited adjustment state, and no lighting adjustment is performed during the current journey of the vehicle; the lighting at positions without passengers is adjusted to a prohibited adjustment state. This achieves zoned management of the vehicle's lighting, with different areas adjusting the lighting status according to different passenger states, ensuring the accuracy of the lighting system control, improving the effectiveness of lighting changes, and enhancing energy savings.

[0097] In some embodiments, before controlling and adjusting the luminous intensity of the lighting system inside the target vehicle based on real-time ambient light intensity and driving information, the method further includes:

[0098] The usage status of the rear seat in-vehicle display screen is obtained by using a current sensor installed on the target vehicle.

[0099] If the rear seat infotainment display is on, the corresponding light will be switched off. Specifically, a current sensor determines the status of the rear seat infotainment display by checking for current flow.

[0100] The rear seat in-vehicle display screen can be a rear seat entertainment screen or a rear seat control screen, etc., and there is no limitation here.

[0101] According to the technical solution provided in this application embodiment, the real-time usage status of the rear seat in-vehicle display screen is obtained through the signal fed back by the current sensor. When it is in the on state, it indicates that the rear passenger is using the rear seat in-vehicle display screen. In this case, the light corresponding to this position will not change according to the aforementioned light control during this trip, thereby protecting the eyesight of passengers using the rear seat in-vehicle display screen, improving the riding experience, and reducing the impact of light control on the eyesight of passengers using the display screen.

[0102] In some embodiments, after controlling and adjusting the luminous intensity of the lighting system inside the target vehicle based on real-time ambient light intensity and driving information, the method further includes:

[0103] Based on the pre-set correspondence between luminous intensity and playback resources, determine the target playback resource corresponding to the adjusted luminous intensity;

[0104] Control the in-vehicle media player to play target playback resources;

[0105] The playback resources include music resources or prompt voice messages.

[0106] Specifically, the pre-set correspondence between light intensity and playback resources means that different light intensities have corresponding playback resources that can be played, which is used to play different resources to the driver under different light intensities.

[0107] In-vehicle media players refer to multimedia playback software that can be installed in a car, including but not limited to music players and video players.

[0108] The target playback resource refers to a playable media resource used to send a wake-up signal to the driver. In this embodiment, it includes music resources or prompt voice. The playback resource, used to remind the driver of driving safety, can be manually input or selected from network resources. Playing this resource provides the driver with a certain auditory stimulus, or the transmitted content can send appropriate reminders to the driver, thus achieving a certain degree of wake-up effect.

[0109] According to the technical solution provided in the embodiments of this application, by controlling the change in the intensity of the in-vehicle lights to provide visual stimulation to the driver, the in-vehicle media player is controlled to play music or voice prompts corresponding to the preset light intensity, providing auditory reminders to the driver. The simultaneous stimulation of multiple senses can progressively wake up the driver from multiple angles. Since there are many ways to alleviate fatigue driving, single sensory stimulation may not be able to achieve an effective wake-up effect. In order to ensure the relief of fatigue driving to a greater extent, a resource playback process is added, which improves the effect of alleviating fatigue driving and enhances driving safety.

[0110] Figure 2 This is a schematic diagram of the architecture of the control method for the lighting system provided in an embodiment of this application. For example... Figure 2 As shown, the components involved in the control process of the lighting system include:

[0111] In-vehicle cameras are used to obtain real-time monitoring information inside the vehicle;

[0112] High-precision maps are used to determine information about tunnels ahead on the road the vehicle is traveling in and the vehicle's location.

[0113] External cameras are used to obtain information about surrounding participants that the vehicle passes by during its driving process;

[0114] A light sensor consists of two components: a projector and a receiver. It focuses ambient light and transmits it via the projector to the receiver. The receiver, based on the photoelectric effect, converts various light signals into corresponding electrical signals, which are then further processed into control actions to achieve the light-sensing adjustment of the light strip.

[0115] Light Emitting Diode (LED) light strips are used to provide appropriate visual stimulation to the driver by changing the intensity or color of the light, thereby reducing driver fatigue during driving.

[0116] A driver monitoring system (DMS) is used to acquire images of the driver and process the data through a controller to obtain relevant parameter values ​​and determine the driver's driving status information.

[0117] According to the technical solution provided in this application, the above components are interconnected. The vehicle can capture and acquire surrounding road information through an external camera, including but not limited to road traffic recognition, information on surrounding participants, and road speed limit information; it can capture and acquire driver images through an in-vehicle camera and a DMS system, analyze key information points, and determine the driver's head state through a controller; it can acquire real-time ambient light intensity through a light sensor, and control the LED light strip to change the light intensity accordingly, thereby reducing the negative impact of ambient light on the driver. Combining the above information, the changes in in-vehicle lighting can alleviate driver fatigue.
