[0036] To more clearly illustrate the technical solutions in this embodiment or the prior art, the drawings used in the description of the embodiment or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0039] Figure 3 This is a structural diagram of a vehicle rear light control system provided in an embodiment of this application. Detailed Implementation
[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0041] As mentioned earlier, with the rapid development of automobiles, increasing emphasis is placed on vehicle safety during operation. However, most current technological development focuses on the driver, with automakers striving to improve the safety of front-seat passengers and the driver, such as by introducing new airbag technologies. There has been little improvement in the safety of rear-seat passengers, especially in today's technological landscape with the rapid development of autonomous vehicles, where drivers will be replaced by artificial intelligence. Therefore, passenger safety is paramount, and more effort should be invested in the passive safety of rear-seat passengers. Current technologies lack solutions specifically designed to ensure rear-seat passenger safety. Consequently, in real-world driving scenarios, other road users cannot pinpoint the exact location of passengers in a dangerous situation, and rescue personnel cannot determine the location of passengers in an accident, resulting in limited timeliness of rescue efforts.
[0042] In view of this, this application provides a method, system, device, and vehicle for controlling rear seat lights. The method involves acquiring an image of the rear seat and the vehicle's status; determining whether there is a passenger in a target seat based on the image; and activating the rear seat lights in a crisis mode if a first passenger is present in the target seat and the vehicle status does not meet a preset safety standard. The rear seat lights are used to identify the position of the first passenger within the vehicle. That is, even when there are passengers in the rear seat, if the vehicle experiences a situation that does not meet preset safety standards, activating the rear seat lights in a danger mode can warn other road users and indicate the current location of passengers by activating the lights, reducing passenger risk and improving passenger passive safety. This provides better and more timely warnings before, during, and after a vehicle crisis, increasing the chances of passenger safety before and during a crisis, and ensuring that passengers are discovered and safely rescued after a crisis.
[0043] The method provided in this application embodiment can be executed by a controller or control unit. The controller can control the OMS (Occupant Monitoring System) camera, i.e., the in-cabin camera, to identify images of the rear seats of the vehicle and thus determine the occupant's location information. The configuration of the rear-seat auxiliary positioning passive safety lighting system can be found in [reference needed]. Figure 1 , Figure 1This is a schematic diagram of the rear-seat auxiliary positioning passive safety lighting system provided in this application embodiment. The rear-seat auxiliary positioning passive safety lighting system consists of a sensor group, a main control unit (controller), and actuators (light source modules). The main controller coordinates and controls the system, combining vehicle information and sensor information to obtain the vehicle status, and issues commands to the actuators, i.e., the light source modules, which execute the light source control according to the main controller's instructions, thus forming effective control of the rear light group to provide visible light warnings for safety. The sensor group may include GPS (Global Positioning System), gyroscope, pressure sensor, light intensity detector, etc., responsible for collecting environmental information and providing it to the main controller. The actuators (i.e., the light source modules) include internal light source modules and external light source modules, responsible for the light source needs inside and outside the vehicle, respectively. After the system starts, it monitors and analyzes the real-time status of CAN (Controller Area Network), LIN (Local Interconnect Network), and sensors. The system's configuration information and basic judgment information are obtained from the vehicle status and user needs acquired by CAN / LIN, and can configure and control the feedback given to the user when the system senses the system.
[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0045] The following embodiment illustrates a method for controlling the rear row lights of a vehicle according to this application. See also... Figure 2 The figure is a flowchart of a vehicle rear light group control method provided in an embodiment of this application. The controller is the main body executing the method, which includes:
[0046] S101. Obtain images of the rear seats inside the vehicle and the vehicle status.
[0047] One or more cameras can be installed inside the vehicle, ensuring that every seat in the rear row is within their field of view. These cameras can be wide-angle cameras. This allows the cameras to capture images of every seat inside the vehicle, and the target seat can be any seat in the rear row.
[0048] S102. Determine whether there is a passenger in the target seat based on the rear seat image inside the vehicle.
[0049] Image recognition technology can be used to identify the acquired images of the rear seats inside the vehicle in order to determine whether there are passengers in the target seat.
[0050] S103. In response to the presence of a first passenger in the target seat and the vehicle status not meeting the preset safety standards, the rear lights are activated with the lighting effects corresponding to the crisis mode.
[0051] The rear lights are used to indicate the location of the first passenger inside the vehicle. Specifically, the system prioritizes assessing whether the current vehicle status does not meet preset safety standards and is in crisis mode. When the vehicle status is detected to be in a state that does not meet preset safety standards, such as sudden braking, stalling, brake failure, skidding, or collision, the crisis mode lighting will be activated to warn other road users and indicate the possible location of the passenger, reducing passenger risk and thus improving passenger passive safety.
[0052] Rear lights can be customized and installed according to the specific layout and requirements of the vehicle. The lights can be mounted on the roof, doors, or rear seats to maximize visibility and usability. In practical applications, high-brightness LED lights can be used to ensure clear visibility in various environmental conditions. This helps others more easily notice passengers behind the vehicle, reducing potential accident risks and improving passenger safety.
[0053] In one possible implementation, the crisis mode includes a warning mode corresponding to when the vehicle status meets a first preset danger standard, the rear lights include vehicle exterior lights, and the step of activating the rear lights with the lighting effect corresponding to the crisis mode in response to the presence of a first passenger in the target seat and the vehicle status not meeting the preset safety standard includes:
[0054] In response to the presence of a first passenger in the target seat and the vehicle status meeting a first preset danger standard, the vehicle's external lights are activated with the first lighting effect corresponding to the warning mode.
[0055] The crisis mode lighting control adjusts its warning capabilities according to the current vehicle's hazard level. The warning mode is activated when the vehicle's hazard level meets the first preset hazard standard; specifically, when the vehicle's hazard level is Level 1, the warning mode is activated. Vehicle Warning Mode: In this mode, the system uses various sensors and monitoring devices to monitor the vehicle's surroundings in real time, providing early warnings of potential hazards to the occupants. For example, when the vehicle approaches an obstacle or other vehicle, the system activates the warning mode, applying the first lighting effect to alert the occupants and prompt them to take appropriate action.
[0056] The first lighting effect includes highlighting the light with a first preset color. For example, the first preset color can be set to red. When the acquired vehicle status indicates that the current vehicle is within a dangerous distance from the vehicle behind, the vehicle's external lights are activated with a bright red light effect to indicate the position of the rear passengers of the current vehicle to the following vehicle.
[0057] In one possible implementation, the crisis mode includes an accident mode corresponding to when the vehicle state meets a second preset danger standard, the rear lights include vehicle exterior lights, and activating the rear lights with the lighting effect corresponding to the crisis mode in response to the presence of a first passenger in the target seat and the vehicle state not meeting the preset safety standard includes:
[0058] In response to the presence of a first passenger in the target seat and the vehicle status meeting the second preset danger standard, the vehicle's external lights are activated with the second lighting effect corresponding to the accident mode.
[0059] Crash Mode is the mode activated when the system detects a vehicle accident. Vehicle accidents are categorized by their severity, including but not limited to collisions, running over, scraping, rollovers, falls, explosions, fires, derailments, and falls or impacts during transport or loading / unloading.
[0060] The second lighting effect includes flashing a light of a second preset color at a first preset frequency. For example, the second preset color can be set to red. When the vehicle status indicates that the vehicle has collided with a road obstacle, the vehicle's external lights are activated with a red flashing effect to alert other road users to the location of the rear passengers and to take evasive action.
[0061] In one possible implementation, the crisis mode includes a rescue mode corresponding to when the vehicle status meets a third preset danger standard, the rear lights include vehicle interior lights, and activating the rear lights with the lighting effect corresponding to the crisis mode in response to the presence of a first passenger in the target seat and the vehicle status not meeting the preset safety standard includes:
[0062] In response to the presence of a first passenger in the target seat and the vehicle status meeting a third preset danger standard, the vehicle interior lights are activated with the third lighting effect corresponding to the rescue mode.
[0063] Rescue Mode: In this mode, the vehicle system is primarily used for rescue and emergency situations. For example, when the vehicle breaks down or stops unexpectedly, the system can send a distress signal via the onboard communication device and provide location information to the emergency rescue team. If external personnel are needed to rescue the occupants, activating Rescue Mode will display the location of the occupants using the corresponding third-light effect, saving time and improving rescue efficiency while ensuring the safety of rear-seat passengers.
[0064] The third lighting effect includes flashing a light of a third preset color at a second preset frequency. For example, the third preset color can be set to red. When the vehicle status indicates that the vehicle has been involved in an accident and the doors are damaged and cannot be opened, and the user has issued a distress signal, the interior lights of the vehicle will be activated with a flashing red light effect to indicate the specific location of the rear passengers in the vehicle to the rescue personnel.
[0065] In one possible implementation, the method provided in this application further includes:
[0066] S104. In response to the presence of a first passenger in the target seat and the vehicle status meeting the preset safety standards, obtain the first passenger's instruction.
[0067] The first passenger instruction includes a target function mode, which is used to characterize the first passenger's need for rear lighting functions.
[0068] S105. Adjust the rear light group to the target lighting effect corresponding to the target function mode.
[0069] This means that the current vehicle status meets the preset safety standards, there are no safety hazards, and it is in normal mode. Passengers can choose auxiliary function modes according to their personal preferences, which can improve comfort while enhancing the sense of technology and ceremony.
[0070] In one possible implementation, adjusting the rear light clusters to the target lighting effect corresponding to the target function mode includes the following four cases:
[0071] Scenario A: When the target function mode is the welcome mode, adjust the rear light group to the fourth or fifth lighting effect corresponding to the welcome mode.
[0072] The vehicle's welcome lighting mode refers to the lights automatically turning on or off as the vehicle approaches or departs, welcoming or bidding farewell to the owner. For example, when the owner approaches the vehicle, the welcome mode will illuminate the lights around the vehicle to provide lighting, making it easier for the owner to enter the car. The fourth lighting effect can be a flashing effect, i.e., a single-color soft light or slow flashing effect; the fifth lighting effect can be a flowing light effect, i.e., multi-color soft light or flowing water effect.
[0073] Scenario B: When the target function mode is tactile mode, adjust the rear light group to the sixth lighting effect corresponding to the tactile mode.
[0074] Haptic mode refers to vehicles equipped with touch-sensitive components, such as door handles and control panels. When the driver touches these areas, haptic mode provides physical feedback, such as vibration or a pulse, to enhance the user's interactive experience and tactile feedback. The sixth lighting effect can adjust the light source color and brightness based on pressure. For example, when a passenger touches the door handle with pressure within a first preset range, the light source color is adjusted to blue corresponding to that range, and the brightness is 30. Correspondingly, the light source color and brightness can differ depending on the touch location and pressure.
[0075] Case C: When the target function mode is privacy mode, adjust the rear light group to the seventh lighting effect corresponding to the privacy mode.
[0076] Privacy mode refers to a vehicle equipped with specific functions to protect the privacy of passengers. For example, some high-end cars can limit outside visibility by adjusting the transparency of curtains or windows, ensuring the privacy of the interior space. The seventh lighting effect can be a single burst of white light that stays on after being activated. In practical applications, the duration of this single burst of white light can be a preset duration, which can be adjusted adaptively according to actual needs and is not limited here.
[0077] Case D: When the target function mode is active mode, adjust the rear light group to the eighth lighting effect corresponding to the active mode.
[0078] Active mode refers to a vehicle's ability to actively sense and respond. For example, some intelligent driving systems can automatically adjust the vehicle's driving mode, speed, and route by sensing the surrounding environment and road conditions to provide a safer and more comfortable driving experience. Active mode can also include functions such as automatic parking, emergency braking, and active obstacle avoidance to enhance the safety of passengers. Rear passengers can activate the rear area lights by actively touching them or through automatic system activation. This helps passengers better locate themselves and provide information to the outside world in special conditions. The eighth lighting effect can be a constant-on effect; the brightness and color of the constant-on effect can be set by the system default or can be adjusted according to user preferences.
[0079] It should be noted that the brightness, color, and other related information for each of the above lighting effects can be determined based on a passenger light usage habit model obtained from the backend server, or based on the default lighting effects set by passengers. For example, the welcome effect in the normal mode can be configured with the welcome animation, color, brightness, frequency, etc., when a passenger first appears at the target location.
[0080] In one possible implementation, after adjusting the rear light group to the eighth lighting effect corresponding to the active mode when the target function mode is active mode, the method further includes:
[0081] In response to a second passenger's instruction, the eighth lighting effect is adjusted according to the second passenger's instruction.
[0082] The second passenger command is used to indicate an adjustment to the color and / or brightness of the eighth lighting effect. For example, if the second passenger command instructs that the lights in the current active mode be adjusted to green, the system will adjust the rear lights to green upon receiving the command.
[0083] Therefore, the rear-seat lighting assembly provided in this application embodiment helps passengers better locate their position and provide external information under special conditions. Furthermore, it can also play a passive safety role in emergency situations. When a collision or sudden braking occurs, the system automatically activates the rear-seat lights to attract the attention of other road users and remind them that there may be passengers behind the vehicle, thus achieving proactive avoidance. When the vehicle is in a safe state, it can provide users with a more comfortable and technologically advanced experience. When the vehicle is in a dangerous state, it is designed to provide additional safety protection for rear-seat passengers. It can provide better and more timely warnings before, during, and after a vehicle crisis, thereby increasing the chances of passengers being safe before and during a crisis, as well as being discovered and safely rescued after a crisis.
