[0023] In the description of this disclosure, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0024] To enable those skilled in the art to better understand this disclosure, a brief description of the application scenarios involved in this disclosure will be given first.

[0025] As is well known, vehicles include multiple lights, which drivers can control to switch on and off as needed. However, in some driving scenarios, such as emergency stops or rear-end collisions, drivers need to activate hazard lights to alert following vehicles to maintain a safe distance and take appropriate driving measures to avoid collisions. Typically, drivers will activate hazard lights in such emergencies. However, in certain situations, such as heavy fog or heavy rain, simply activating hazard lights may not provide sufficient brightness, preventing following vehicles from noticing the abnormal situation and taking timely braking action. Therefore, this disclosure proposes a vehicle lighting control method to improve the accurate control of vehicle lights and enhance driving safety.

[0026] Referring to FIG1, a flowchart of a vehicle lighting control method according to some embodiments of the present disclosure is shown, which can be executed by a device having computing processing capabilities.

[0027] Referring to Figure 1, the vehicle lighting control method includes at least the following steps:

[0028] Step 110: Determine the current speed of the vehicle behind the current vehicle. The current vehicle includes multiple lights, and the light-emitting area of ​​the lights and the brightness of each individual LED are adjustable.

[0029] Step 120: Determine the safe display distance required for the lights emitted by the lamps based on the current speed of the vehicles behind.

[0030] Step 130: Determine the target number of lights to be activated based on the safe display distance.

[0031] Step 140: Determine the required luminous power of the lights within the preset warning range based on the meteorological data of the area where the vehicle is currently located.

[0032] Step 150: Control the lights of the current vehicle according to the target number of lights to be activated and the luminous power, so that the number of lights to be activated in the current vehicle is the target number of lights to be activated, and the visible distance of the light emitted by the activated lights is the safe display distance.

[0033] It should be noted that steps S110-S130 are used to determine the target number of lamps to be activated, and step S140 is used to determine the required luminous power of the lamps within the preset warning range. In some embodiments, steps S110-S130 and step S140 can be executed simultaneously, or steps S110-S130 can be executed first and then step S140, or step S140 can be executed first and then steps S110-S130. In the following description, only the example of "executing steps S110-S130 first and then step S140" will be used.

[0034] The "current vehicle" refers to the vehicle requiring headlight control. This vehicle includes multiple headlights, and the luminous area and brightness of individual LEDs can be adjusted via the vehicle's central controller. When controlling the headlights of the current vehicle, the current speed of vehicles behind it can be determined first. Then, based on the speed of the vehicles behind, the required safe visibility distance for the headlights of the current vehicle can be determined. In other words, how bright should the headlights be to ensure that drivers of vehicles behind can see the warning lights within a certain distance, allowing for timely adjustments such as lane changes or emergency braking? Therefore, based on this determined safe visibility distance, the target number of headlights to activate can be determined—that is, how many LEDs need to be lit to ensure visibility within the safe visibility distance.

[0035] In some implementations, weather conditions in the area where the vehicle is located also need to be considered. Therefore, meteorological data for the area can be obtained first, and then the required luminous power of the lights within the preset warning range can be determined based on the meteorological data. In one embodiment, it can be understood that the preset warning range in this embodiment can be a range determined according to traffic regulations. For example, the preset warning range can refer to an area with a radius of 90 to 110 meters centered on the current vehicle. Then, the lights of the current vehicle can be controlled according to the target number of lights to be activated and the required luminous power of the lights within the preset warning range based on the current weather conditions, so that the number of lights activated is the target number, and the visible distance of the activated lights is the safe display distance. In this way, the lights of the current vehicle can be precisely controlled according to the speed of vehicles behind and the current weather conditions, without wasting excess energy, allowing the function to continue for a longer period of time, and ensuring the driving safety of the user.

[0036] In one embodiment, determining the current speed of a vehicle behind the current vehicle includes: if the current vehicle's travel time is greater than or equal to a preset travel time, determining the average speed of the current vehicle within the preset travel time before the current moment, and using the average speed as the current vehicle's current speed; if the current vehicle's travel time is less than the preset travel time, determining the speed limit value of the current vehicle in the current area as the current vehicle's current speed; and determining the current speed of a vehicle behind the current vehicle based on the current vehicle's current speed.

[0037] This embodiment provides two implementation methods for determining the current speed of vehicles behind the current vehicle. The first method involves determining the average speed of the current vehicle within the preset travel time if the current vehicle's travel time is greater than or equal to a preset travel time. This average speed is then used as the current vehicle's current speed, and the current speed of vehicles behind the current vehicle can be determined based on this current speed. The second method involves determining the current speed of the current vehicle if the current vehicle's travel time is less than the preset travel time. This involves determining the current vehicle's current speed based on the speed limit within the current area, and then determining the current speed of vehicles behind the current vehicle based on this current speed. Specifically, the speed limit within the current area can be the maximum speed limit suggested by the navigation system used by the driver for the current vehicle on the current road segment, or it can be the maximum speed limit for the current vehicle model on the current road segment according to traffic regulations. In one embodiment, the preset travel time can be set to 8 to 12 minutes, such as 10 minutes. This means that if the current vehicle's travel time exceeds 10 minutes, the average speed of the current vehicle within the 10 minutes prior to the current moment can be determined, and this average speed can be used as the current vehicle's current speed. If the current vehicle's travel time is less than 10 minutes, the speed limit value of the current vehicle in the current area can be determined as the current vehicle's current speed.

[0038] In one embodiment, determining the current speed of a vehicle behind the current vehicle based on the current vehicle's current speed includes: multiplying the current vehicle's current speed by a preset value to obtain the speed of the vehicle behind the current vehicle.

[0039] After determining the current speed of the current vehicle, a preset value can be multiplied from the current speed of the current vehicle, and then the product can be used to determine the current speed of the vehicle behind. In some implementations, the preset value can be set to 1.15 to 1.25.

[0040] In one embodiment, determining the required safe display distance for the lights emitted by the lamps based on the current speed of the vehicles behind includes: determining a safe redundancy distance and a safe reaction time; determining a first distance based on the safe reaction time and the current speed of the vehicles behind; adding a safe redundancy distance to the first distance to obtain a second distance; and using the second distance as the required safe display distance for the lights emitted by the lamps.

[0041] After determining the current speed of the vehicle behind, a safety redundancy distance and a safe reaction time can be determined first. Then, based on the safe reaction time and the current speed of the vehicle behind, a first distance is determined. This first distance is the distance required from when the driver of the vehicle behind reacts and begins braking until the vehicle behind truly stops, based on the current speed of the vehicle behind and the preset safe reaction time of the driver. Adding the safety redundancy distance to the first distance yields a second distance, which can be understood as the safe display distance required for the headlights of the current vehicle. It can be seen that the safety redundancy distance and the safe reaction time can be customized. In an optimized implementation, an image acquisition device such as a camera can be installed at the rear of the current vehicle to capture images of the vehicle behind and determine its model. Therefore, when determining the safety redundancy distance and / or the safe reaction time, adjustments can be made based on the vehicle model of the vehicle behind. For example, assuming the vehicle behind is a pure electric vehicle of a certain brand, the safety redundancy distance can be shorter compared to a pure gasoline vehicle of the same brand. The specific values ​​can be set based on the vehicle's braking test data, which will not be elaborated here.

[0042] In one implementation, the safety redundancy distance is 55 to 75 meters, and the safety response time is 1.3 to 1.7 seconds.

[0043] In one embodiment, determining the target number of luminaires to be activated based on the safe display distance includes: determining the luminous area that the luminaires need to guarantee while meeting the safe display distance; and determining the target number of luminaires to be activated based on the luminous area.

[0044] After determining the current speed of the vehicles behind, the required safe display distance for the lights can be determined based on that speed. Then, the required luminous area of ​​the lights to maintain that safe display distance can be determined; that is, the luminous area the lights should cover at that safe display distance so that drivers or passengers in following vehicles can see the warning lights in time. Therefore, after determining the required luminous area for that safe display distance, the target number of lights to activate can be determined based on that luminous area; that is, how many LEDs need to be lit to ensure that the luminous area of ​​the lights is sufficient for following vehicles to see the warning lights clearly and promptly.

[0045] In some embodiments of this disclosure, the required safe display distance of the lights is determined by the current speed of vehicles behind the current vehicle. A target number of lights is then determined based on this safe display distance. Next, meteorological data for the area where the current vehicle is located is used to determine the required luminous power of the lights within a preset warning range. Based on the target number of lights to be activated and the luminous power, the lights of the current vehicle are controlled so that the number of lights activated is the target number, and the visible distance of the activated lights is the safe display distance. This embodiment allows for precise control of light power, avoids wasting excess energy, enables the function to continue for a longer period, and ensures the driving safety of the user.

[0046] In one embodiment, Figure 2 shows a flowchart of a vehicle lighting control method according to other embodiments of the present disclosure. The "current vehicle" refers to the vehicle requiring lighting control. The current vehicle includes multiple lights, and the luminous area and brightness of individual LEDs of the lights can be adjusted by the vehicle's central controller. When the lights of the current vehicle need to be controlled, the current speed of the vehicles behind the current vehicle can be determined first. Then, based on the current speed of the vehicles behind, the required safe display distance for the lights emitted by the current vehicle can be determined. That is, how bright the lights of the current vehicle need to be to ensure that the drivers of the following vehicles can see the warning lights within a certain distance, so as to take timely action, such as changing lanes or emergency braking. Therefore, the current vehicle can determine the target number of lights to be activated based on the determined safe display distance, that is, how many LEDs need to be lit to ensure the visibility of the lights emitted within the safe display distance.

[0047] This embodiment provides two implementation methods for determining the current speed of vehicles behind the current vehicle. The first method involves determining the average speed of the current vehicle within the preset travel time if the current vehicle's travel time is greater than or equal to a preset travel time. This average speed is then used as the current vehicle's current speed, and the current speed of vehicles behind the current vehicle can be determined based on this current speed. The second method involves determining the current speed of the current vehicle if the current vehicle's travel time is less than the preset travel time. This involves determining the current vehicle's current speed based on the speed limit within the current area, and then determining the current speed of vehicles behind the current vehicle based on this current speed. Specifically, the speed limit within the current area can be the maximum speed limit suggested by the navigation system used by the driver for the current vehicle on the current road segment, or it can be the maximum speed limit for the current vehicle model on the current road segment according to traffic regulations. In one embodiment, the preset travel time can be set to 8 to 12 minutes, for example, 10 minutes. This means that if the current vehicle's travel time exceeds 10 minutes, the average speed of the current vehicle within the 10 minutes preceding the current moment can be determined, and this average speed can be used as the current vehicle's current speed. If the current vehicle's travel time is less than 10 minutes, the speed limit value of the current vehicle in the current area can be determined as the current vehicle's current speed. After determining the current vehicle's current speed, a preset value can be multiplied by the current vehicle's current speed, and this product can be used to determine the current speed of the vehicles behind. In some embodiments, the preset value can be set to 1.15-1.25.

[0048] After determining the current speed of the vehicle behind, a safety redundancy distance and a safe reaction time can be determined first. Then, based on the safe reaction time and the current speed of the vehicle behind, a first distance is determined. This first distance is the distance required from when the driver of the vehicle behind reacts and begins braking until the vehicle behind truly stops, based on the current speed of the vehicle behind and the preset safe reaction time of the driver. Adding the safety redundancy distance to the first distance yields a second distance, which can be understood as the safe display distance required for the headlights of the current vehicle. It can be seen that the safety redundancy distance and the safe reaction time can be customized. In an optimized implementation, an image acquisition device such as a camera can be installed at the rear of the current vehicle to capture images of the vehicle behind and determine its model. Therefore, when determining the safety redundancy distance and / or the safe reaction time, adjustments can be made based on the vehicle model of the vehicle behind. For example, assuming the vehicle behind is a pure electric vehicle of a certain brand, the safety redundancy distance can be shorter compared to a pure gasoline vehicle of the same brand. The specific values ​​can be set based on the vehicle's braking test data, and will not be elaborated here. In one specific embodiment, the safety redundancy distance L is 55 to 75 meters, and the safety reaction time t is 1.3 to 1.7 seconds.

[0049] In some implementations, it is also necessary to consider the weather conditions in the area where the vehicle is currently located. Therefore, meteorological data for the area where the vehicle is currently located can be obtained first, and then the required luminous power of the lights within the preset warning range can be determined based on the meteorological data. In one embodiment, it can be understood that the preset warning range in this embodiment can be a range determined according to traffic regulations. For example, the preset warning range can refer to an area with a radius of 90 to 110 meters centered on the current vehicle.

[0050] After determining the current speed of the vehicles behind, the required safe display distance for the lights can be determined based on that speed. Then, the required luminous area of ​​the lights to maintain that safe display distance can be determined; that is, the luminous area the lights should cover at that safe display distance so that drivers or passengers in following vehicles can see the warning lights in time. Therefore, after determining the required luminous area for that safe display distance, the target number of lights to activate can be determined based on that luminous area; that is, how many LEDs need to be lit to ensure that the luminous area of ​​the lights is sufficient for following vehicles to see the warning lights clearly and promptly.

[0051] In some embodiments of this disclosure, the required safe display distance of the lights is determined by the current speed of vehicles behind the vehicle. Based on this safe display distance, a target number of lights is activated. Then, based on meteorological data of the area where the vehicle is located, the required luminous power of the lights within a preset warning range is determined. The lights of the vehicle are controlled based on the target number of activations and the luminous power, ensuring that the number of activated lights matches the target number and that the visible distance of the activated lights is within the safe display distance. This embodiment achieves precise control of light power, avoids wasting excess energy, allows for longer operation, and ensures user driving safety. Simultaneously, it solves the problems of traditional technologies requiring personnel to disembark and place warning triangles, and the inadequacy of the warning triangle's distance.
