[0079] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this disclosure can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0081] In related technologies, automotive decorative lighting, as an important configuration that can enhance the overall vehicle atmosphere and user experience, is receiving increasing attention from major OEMs. Interior ambient lighting, in particular, not only provides illumination but also integrates with systems such as in-vehicle audio and air conditioning for intelligent control, offering users a more convenient and comfortable driving experience. However, compared to interior ambient lighting, the development of exterior decorative lighting remains relatively limited. Although some OEMs have created a degree of diversity in exterior lighting through headlight light shows or taillights displaying special characters, there is still significant room for improvement in enhancing the user experience and human-vehicle interaction. To address these technical issues, this disclosure proposes a lighting effect control method applicable to various scenarios, including but not limited to sentry mode, welcome / farewell mode, standby mode, and charging / discharging mode, which can enhance the user experience and human-vehicle interaction.

[0082] Figure 1 This is a schematic diagram illustrating the steps of a lighting effect control method according to an embodiment of this disclosure. Figure 1 As shown, the lighting effect control method may specifically include the following steps:

[0083] Step S11: Determine whether the lighting effect switch corresponding to each lighting mode is turned on.

[0084] Users can turn the rear quarter window light vehicle status indicator, rear quarter window light safety indicator, and rear quarter window light welcome / farewell light on / off via the vehicle's infotainment system interface, and customize the corresponding prompts and lighting scenes as needed. Specifically, the user's soft switch settings are transmitted from the in-vehicle infotainment terminal assembly HU2 to the body control assembly BDC7 via the CAN bus.

[0085] Table 1 shows the correspondence between soft switches and lighting scenes, where each soft switch can be turned on or off individually.

[0086]

[0087]

[0088] Table 1

[0089] Before the rear triangular window displays the corresponding lighting effects according to the signal, it is necessary to first determine whether the soft switch corresponding to the signal is in the on state. The on state of the soft switch is the most prerequisite for executing the subsequent steps.

[0090] The "Rear Triangle Window Light Vehicle Status Indicator" can be used to control the lighting effects in charging / discharging mode and standby mode; the "Rear Triangle Window Light Welcome / Farewell Light" can be used to control the lighting effects in welcome / farewell mode; and the "Rear Triangle Window Light Safety Indicator" can be used to control the lighting effects in sentry mode.

[0091] Step S12: When the lighting effect switch is turned on, receive the lighting control signal corresponding to the lighting mode.

[0092] When the lighting effect switch, also known as the soft switch, is turned on, it receives the lighting control signal for the corresponding lighting mode. For example, when the "rear quarter window light vehicle status indicator" soft switch is turned on, it can receive the lighting control signals corresponding to the charging / discharging mode and the standby mode.

[0093] Step S13: Obtain the priority of the lighting mode; the lighting modes, in descending order of priority, include: Sentry Mode, Welcome Mode, Standby Mode, and Charging / Discharging Mode.

[0094] The lighting effects corresponding to Sentry Mode, Welcome Mode, Standby Mode, and Charging / Discharging Mode can only be activated when the vehicle is in Park (P) gear.

[0095] When multiple lighting control signals corresponding to different lighting modes are received, each lighting mode is assigned a priority to prevent conflicts. The lighting modes are arranged in order of priority from high to low: Sentry Mode, Welcome Mode, Standby Mode, and Charging / Discharging Mode.

[0096] A priority list can be preset. When the priority of a lighting mode needs to be obtained, the system will query this priority list. Internally, the system can have a comparison logic to determine which lighting mode has the highest priority in the current situation. Once the highest-priority lighting mode is selected, the system updates its internal state to ensure this information is synchronized throughout the entire control system for subsequent control signal sending and execution. When multiple lighting mode requests occur simultaneously, priority conflicts can be handled to ensure that high-priority modes are not interfered with by low-priority requests.

[0097] Table 2 shows the correspondence between various lighting modes and priorities. When multiple lighting modes exist, the lighting mode with the highest priority is executed.

[0098]

[0099]

[0100] Table 2

[0101] After a high-level lighting mode finishes executing its corresponding lighting effect, it can directly revert to the previous lighting effect. For example, if the lighting effect corresponding to the standby mode is currently being executed, but the sentry mode suddenly detects an anomaly, since the sentry mode has the highest lighting effect level, the standby mode lighting effect will be stopped and the sentry mode lighting effect will be executed. Once the sentry mode detects that the anomaly has disappeared, the sentry mode lighting effect will stop executing and the standby mode lighting effect will be restored. Alternatively, after each lighting effect is executed, the system can re-detect the lighting control signals that are currently requesting lighting effects, determine the priority of the lighting mode corresponding to each lighting control signal, and execute the lighting effect corresponding to that lighting control signal based on the priority of the lighting mode. Specifically, if the lighting effect currently being executed is the sentry mode lighting effect, then when the sentry mode lighting effect finishes execution and needs to be restored to its original state lighting effect, if the original state lighting effect is the standby mode or charging / discharging mode lighting effect, then restoration will be performed; if the original state lighting effect is the welcoming / farewell mode lighting effect, then restoration will not be performed.

[0102] Step S14: Determine the light control signal corresponding to the light mode with the highest priority as the target light control signal;

[0103] When there are multiple lighting control signals corresponding to different lighting modes, the lighting control signal with the highest priority is selected as the target lighting control signal.

[0104] Step S15: Control the rear quarter window light assembly to execute the lighting effect corresponding to the target lighting control signal.

[0105] By employing embodiments of this disclosure, and setting an on / off state for each lighting mode, the system can flexibly control when to activate specific lighting effects, turning lights on or off flexibly according to actual conditions, thus enhancing the flexibility and adaptability of vehicle use. It can manage the priority of multiple lighting modes, ensuring that when multiple modes request activation simultaneously, the most important lighting mode is executed according to a preset priority order. Through preset priority logic, the system can quickly determine and execute the highest priority lighting mode, improving the system's response speed and efficiency. Figure 2 This is a schematic diagram of a rear quarter window light assembly control system according to an embodiment of this disclosure. Figure 2As shown, the system includes a vehicle control APP1, an in-vehicle infotainment terminal assembly HU2, a powertrain domain controller PDCU3, a Bluetooth module BLEM4, a data acquisition module DCM5, an intelligent driving domain controller MDC6, a body controller assembly BDC7, an air conditioning control module ACM8, and a rear quarter window light assembly 9. The vehicle control APP1 controls the in-vehicle infotainment terminal assembly HU2 via a 4G / 5G network to perform charging reservations and remote vehicle standby operations. The in-vehicle infotainment terminal assembly HU2 sends signals to the body controller assembly BDC7 via the CAN bus, including "rear quarter window light vehicle status indicator," "rear quarter window light safety indicator," and "rear quarter window light welcome / farewell light" on / off signals, a charging mode signal, and a user-defined C-pillar light color signal. The powertrain domain controller PDCU3 sends a battery level signal to the body controller assembly BDC7 via the CAN bus. The Bluetooth module BLEM4 receives the location information from the Bluetooth key and sends the welcome / farewell mode signal to the body controller assembly. BDC7; The data acquisition module DCM5 sends the acquired external status signals to the intelligent driving domain controller MDC6. When the intelligent driving domain controller MDC6 identifies an anomaly, it sends a warning signal to the body controller assembly BDC7. After receiving the remote standby signal, the body controller assembly BDC7 sends a control signal to the air conditioning control module ACM8. After successful standby, the air conditioning control module ACM8 responds with a success signal to the body controller assembly BDC7. The body controller assembly BDC7 directly controls the rear quarter window light assembly 9, and sends signals such as switch status, lighting mode, and fault to the rear quarter window light assembly 9 through the LIN bus to meet the lighting needs of different scenarios.

[0106] In one optional embodiment, receiving the lighting control signal corresponding to the lighting mode includes: receiving a charging / discharging signal; when the target lighting control signal is the lighting control signal corresponding to the charging / discharging mode, controlling the rear quarter window light assembly to execute the lighting effect corresponding to the target lighting control signal includes: detecting whether a fault signal exists at the current moment; the fault signal indicates that the vehicle has a charging / discharging abnormality; when the fault signal exists, controlling the rear quarter window light assembly to execute a charging fault lighting effect; when the fault signal does not exist, detecting the charging type of the charging / discharging signal; the charging type includes scheduled charging and plug-and-charge; when the charging type is scheduled charging, controlling the rear quarter window light assembly to execute a scheduled charging lighting effect; when the charging type is plug-and-charge, acquiring a power signal; the power signal is used to represent the current power level; acquiring the correspondence between multiple power level ranges and charging / discharging lighting effects; wherein the power level ranges do not overlap; determining the target power level range where the current power level is located, and controlling the rear quarter window light assembly to execute the charging / discharging lighting effect corresponding to the target power level range; wherein the charging / discharging lighting effects corresponding to different power level ranges are different.

[0107] Before receiving charging and discharging signals, it is necessary to check whether the soft switch for charging and discharging mode is turned on, that is, whether the rear quarter window light vehicle status indicator is turned on. This soft switch can be defined as:

[0108] HU_CPillarLampVehSts = 0x1 on (on)

[0109] HU_CPillarLampVehSts = 0x2 off (off)

[0110] When HU_CPillarLampVehSts = 0x1 is detected, it indicates that the "Rear Triangle Window Light Vehicle Status Indicator" soft switch is on, and subsequent steps for receiving charging / discharging signal lights can be executed. If HU_CPillarLampVehSts = 0x2 is detected, then no lighting effects included in the charging / discharging mode are executed.

[0111] The system receives charging and discharging signals, which control the rear quarter window lights to execute the lighting effects corresponding to the charging and discharging modes. Before executing the lighting effects corresponding to the charging and discharging signals, it is also necessary to detect whether a fault signal exists. A fault signal indicates that the vehicle is experiencing charging or discharging abnormalities. If a fault signal exists, the rear quarter window light assembly is controlled to execute the lighting effects corresponding to the fault signal to warn the driver, etc. If no fault signal exists, the rear quarter window light assembly is controlled to execute the lighting effects corresponding to the charging and discharging signals. The charging type of the charging and discharging signals can be divided into scheduled charging and plug-and-charge. Scheduled charging means that charging will only begin when the scheduled time arrives, while plug-and-charge means that charging will begin when the signal is received. When the charging type is scheduled charging, the rear quarter window light assembly is controlled to execute the scheduled charging lighting effects.

[0112] The charge / discharge type can be defined as:

[0113] PCU_ChrgMode = 0x1 Scheduled charging;

[0114] PCU_ChrgMode = 0x0 Plug and charge

[0115] When the detected charging / discharging signal is PCU_ChrgMode=0x1, the signal indicates scheduled charging; when the detected charging / discharging signal is PCU_ChrgMode=0x0, the signal indicates plug-and-charge.

[0116] When the charging type is plug-and-charge, the rear quarter window light assembly is controlled to execute a plug-and-charge lighting effect. This effect reflects the vehicle's current battery level in real time and sets lighting effects that match the battery level. Specifically, the body controller assembly BDC7 detects the battery's State of Charge (SOC) signal and drives the number of LEDs illuminated in the rear quarter window light assembly 9 according to the SOC. The rear quarter window light has three individually controllable illumination areas (A, B, and C), representing three different battery levels.

[0117] The relationship between battery level and charging / discharging lamp effect can be defined as follows:

[0118] When PCU_SOC = 0% to PCU_SOC = 33%, area A displays a green breathing light effect, while areas B and C are off.

[0119] When PCU_SOC = 34% to 66%, area A is constantly lit, area B has a green breathing light effect, and area C is off.

[0120] When PCU_SOC = 67% to 99%, areas A and B are constantly lit, while area C displays a green breathing light effect.

[0121] When PCU_SOC = 100%, areas A, B, and C are always lit.

[0122] By employing embodiments of this disclosure, timely display of fault lighting effects can quickly alert the driver or surrounding personnel to potential charging problems, enabling timely measures to prevent accidents. Different charging types and battery statuses are displayed through different lighting effects, making the vehicle's status readily apparent and enhancing the user's understanding of the vehicle's battery level and charging status. Precise control of the lighting effects can provide users with customized visual feedback, such as different prompts for scheduled charging and plug-and-charge, enhancing user satisfaction. Through refined battery range management and corresponding lighting effects, the system can more intelligently manage battery usage, predict battery consumption, and support future smart grid integration.

[0123] In one optional embodiment, the step of responding to the fault signal includes: acquiring the fault type of the fault signal; the fault type includes system fault and charging / discharging gun connection abnormality fault; the step of controlling the rear quarter window light assembly to perform a charging fault lighting effect when the fault signal is present includes: controlling the rear quarter window light assembly to perform a first fault lighting effect when the fault type is system fault; controlling the rear quarter window light assembly to perform a second fault lighting effect when the fault type is charging / discharging gun connection abnormality fault; wherein the first fault lighting effect and the second fault lighting effect are different.

[0124] Before controlling the rear quarter window light to perform charging / discharging lighting effects via charging / discharging signals, a fault signal is detected. If a fault signal is present, the fault type is determined. Fault types include system faults and charging / discharging gun connection abnormalities. System faults can be caused by malfunctions of major system components such as the battery, motor, and controller. Charging / discharging gun connection abnormalities can be caused by poor physical connections, communication failures, or problems with the charging equipment itself. In the case of a system fault, the rear quarter window light assembly is controlled to perform a first fault lighting effect; in the case of a charging / discharging gun connection abnormality, the rear quarter window light assembly is controlled to perform a second fault lighting effect. The first and second fault lighting effects are different. The fault types can be defined as:

[0125] HU_CPillarLampSysErr = 0x1~0x7 System fault

[0126] PCU_ChrgCnctrErr = 0x1 Charge / discharge gun connection abnormality fault.

[0127] The Body Control Controller (BDC) system detects fault signals. When a system fault or a charging / discharging gun connection malfunction is detected, the BDC controls the rear quarter window light assembly to execute the corresponding lighting effect. The lighting effect corresponding to a system fault is a solid red light, and the lighting effect corresponding to a charging / discharging gun connection malfunction is a red breathing light.

[0128] By employing embodiments of this disclosure and using different lighting effects to indicate different types of faults, the system can provide drivers with clear and easily identifiable visual feedback. These differentiated lighting effects can quickly inform the driver of specific vehicle problems, enabling the driver to react accordingly. Different fault lighting effects not only provide drivers with clear indications of the fault type but also facilitate quick identification of the problem's source by maintenance personnel. This can significantly shorten diagnostic time, improve maintenance efficiency, and reduce vehicle maintenance costs.

[0129] Figure 3 This is a flowchart illustrating a charging / discharging mode lighting control according to an embodiment of this disclosure. Figure 3As shown, the process first checks whether the soft switch for charging / discharging modes is enabled. The BDC (Body Control Controller Assembly) checks for the presence of the signal HU_CPillarLampVehSts = 0x1. If HU_CPillarLampVehSts = 0x1 is not detected, all charging / discharging mode lighting effects are stopped. If HU_CPillarLampVehSts = 0x1 is detected, the BDC again checks whether the fault signal is fault-free. If the fault signal is faulty, the BDC controls the rear quarter window light assembly to execute the corresponding fault lighting effect based on the fault type. If the fault signal is fault-free, the BDC checks whether the charging / discharging signal is in a scheduled charging mode. If the charging / discharging signal is in a scheduled charging mode, the BDC controls the rear quarter window light assembly to execute the scheduled charging lighting effect. If the charging / discharging signal is not in a scheduled charging mode, the BDC controls the rear quarter window light assembly to execute the real-time power lighting effect by receiving the SOC value of the power signal.

[0130] In one optional embodiment, receiving the lighting control signal corresponding to the lighting mode includes: receiving a standby request signal; controlling the air conditioner to start in response to the standby request signal; detecting whether the air conditioner is started; sending an air conditioner start signal if the air conditioner is started; and controlling the rear quarter window light assembly to execute the lighting effect corresponding to the target lighting control signal when the target lighting control signal is the lighting control signal corresponding to the standby mode, including: detecting whether charging or discharging is in progress when the current battery level is higher than or equal to a first threshold; controlling the rear quarter window light assembly to execute a first standby lighting effect in response to the air conditioner start signal if charging or discharging is in progress; and controlling the rear quarter window light assembly to execute a second standby lighting effect in response to the air conditioner start signal if charging or discharging is not in progress; wherein the first standby lighting effect and the second standby lighting effect are different.

[0131] Before implementing the lighting effects corresponding to the standby mode, it's necessary to check whether the soft switch for charging / discharging mode is enabled, i.e., whether the rear quarter window light vehicle status indicator is on. This soft switch can be defined as: HU_CPillarLampVehSts = 0x1 on (on).

[0132] HU_CPillarLampVehSts = 0x2 off (off)

[0133] When HU_CPillarLampVehSts = 0x1 is detected, it indicates that the "Rear Quarter Window Light Vehicle Status Indicator" soft switch is on, and the lighting effects corresponding to the standby mode can be executed. If HU_CPillarLampVehSts = 0x2 is detected, then none of the lighting effects included in the standby mode will be executed.

[0134] The vehicle infotainment terminal assembly HU2 receives a remote vehicle standby request from the mobile control APP1. The remote vehicle standby request is implemented through a standby request signal. In response to the standby request signal, the air conditioning mode signal is sent to the air conditioning control module ACM8 via the CAN bus. The system detects whether the air conditioning is started. If the air conditioning is started, an air conditioning start signal is sent. Specifically, after the air conditioning is turned on, the air conditioning control module ACM8 sends a successful start signal to BDC7 via the CAN bus.

[0135] Before controlling the rear quarter window light assembly to execute the lighting effect corresponding to the standby mode via the air conditioning start signal, it is necessary to determine whether the vehicle is in a low battery state. This can be done by receiving a battery signal and determining whether the battery information carried by the signal is lower than a preset value. If it is lower than the preset value, it is in a low battery state, and the vehicle's rear quarter window needs to be controlled to execute the low battery warning lighting effect corresponding to the low battery mode.

[0136] The low battery warning light effect can be defined as the rear quarter window light assembly 9 controlled by the body controller assembly BDC7 flashing orange to warn of low battery, with a flashing period of 500ms.

[0137] When the vehicle is not in a low battery state, the rear quarter window light assembly is controlled by the air conditioning start signal to execute the lighting effects corresponding to the standby mode. The lighting effects corresponding to the standby mode for the rear quarter window light assembly include standby lighting effects when the vehicle is charging or discharging, and standby lighting effects when the vehicle is not charging or discharging. The presence of a charging or discharging signal can be monitored to determine whether the vehicle is charging or discharging. Specifically, the standby lighting effects can be defined as follows:

[0138] Vehicle ready (when not charging) - Areas A, B, and C flash ice blue in a clockwise sequence for 200ms;

[0139] Vehicle ready (during charging / discharging) - The A, B, and C illuminated areas and lighting effects are the same as the charging / discharging scenario settings under the current battery level, and the color changes to ice blue.

[0140] By employing embodiments of this disclosure, the air conditioning is automatically activated and vehicle status is displayed through lighting effects, providing immediate environmental adjustments and clear status information, increasing the user's understanding and control of the vehicle's real-time status. In standby mode, different lighting effects clearly indicate the vehicle's specific status, such as whether it is charging or ready, which helps the driver or maintenance personnel understand and respond to the vehicle's needs. By intelligently detecting battery level and charging / discharging status, and controlling the air conditioning in a timely manner, energy use is optimized, providing a comfortable environment for the driver.

[0141] In one optional embodiment, during the process of controlling the rear quarter window light assembly to execute the first standby lighting effect or the second standby lighting effect, the method further includes: detecting whether the door is unlocked; and if the door is unlocked, controlling the rear quarter window light assembly to cancel the lighting effect corresponding to the standby mode.

[0142] The system controls the rear quarter window light assembly to display either the first or second standby lighting effect based on the vehicle's battery level and charging / discharging status. During this process, it is necessary to monitor in real time whether the vehicle doors are unlocked, which can be achieved through the vehicle's central control system or door lock sensors.

[0143] If the system detects that a door is unlocked, it will instruct the rear quarter window light to cancel the currently displayed standby light effect. If the door remains locked, the standby light effect will continue to be displayed to maintain the correct indication of the vehicle status.

[0144] By employing embodiments of this disclosure, the locking status of vehicle doors is monitored in real time, and lighting effects are adjusted accordingly. This enables the vehicle to dynamically adjust lighting cues based on door status, increasing the vehicle's intelligent interactivity and providing feedback more relevant to the current state to users or external observers. By integrating door status and lighting effect control, the vehicle management system can more accurately control and manage various vehicle status indicators, making vehicle operation more consistent with actual usage conditions.

[0145] Figure 4 This is a flowchart illustrating a standby mode lighting control method according to an embodiment of this disclosure. Figure 4 As shown, the first step is to check if the soft switch for charging / discharging mode is enabled. The BDC (Body Controller Assembly) checks if HU_CPillarLampVehSts = 0x1. If HU_CPillarLampVehSts = 0x1 is not detected, the process ends directly. If HU_CPillarLampVehSts = 0x1 is detected, the BDC checks if the battery SOC value is greater than 20%. If the SOC value is not greater than 20%, a low battery warning light effect is activated. If the SOC value is greater than 20%, the low battery warning light effect is activated. The BDC (Browser Control Center) detects whether the air conditioning has been successfully turned on remotely, which can be determined by the signal AC_RmoteStatrSts = 0x1. If the air conditioning has been successfully turned on remotely, the BDC monitors whether the rear quarter window of the vehicle is performing a charging / discharging light effect. If it is performing a charging / discharging light effect, then in conjunction with the air conditioning start signal, the BDC controls the rear quarter window to perform standby light effect 2. During the performance of standby light effect 1 or standby light effect 2, the BDC continuously monitors whether the door is open. If the door is open, the BDC controls the rear quarter window to perform standby light effect 1 or standby light effect 2.

[0146] In one optional embodiment, receiving the lighting control signal corresponding to the lighting mode includes: acquiring a pre-set welcome / send-off area and detecting the area where the user is located in real time; sending a welcome signal when the user moves from outside the welcome / send-off area to the welcome / send-off area, and / or when the user actively unlocks the door; sending a guest signal when the user moves from the welcome / send-off area to outside the welcome / send-off area, and / or when the user actively locks the door; and controlling the rear quarter window light assembly to execute the lighting effect corresponding to the target lighting control signal when the target lighting control signal is the lighting control signal corresponding to the welcome / send-off mode, including: when the current battery level is higher than or equal to a first threshold, controlling the rear quarter window light assembly to execute a welcome lighting effect or a guest farewell lighting effect in response to the welcome signal or the farewell signal.

[0147] Before implementing the lighting effects corresponding to the welcome / farewell mode, it is necessary to check whether the soft switch for the welcome / farewell mode is turned on, that is, whether the soft switch for the rear quarter window welcome / farewell lights is turned on. This soft switch can be defined as: HU_CPillarLampWelSts = 0x1 on (on);

[0148] HU_CPillarLampWelSts = 0x2 off (off).

[0149] When HU_CPillarLampWelSts = 0x1 is detected, it indicates that the soft switch for the rear quarter window welcome light is on; when HU_CPillarLampWelSts = 0x2 is detected, it indicates that the soft switch for the rear quarter window welcome light is off.

[0150] A welcome / farewell zone can be set up within a certain area around the vehicle. Sensors can monitor the user's location in real time to determine whether the user has entered or left the welcome / farewell zone. Specifically, the BDC7 body control assembly can detect the physical key, or the BLEM4 Bluetooth module can detect whether the user has entered or exited the defined welcome zone. Simultaneously, the system also needs to detect whether the user has unlocked or locked the vehicle. When the user enters the welcome / farewell zone or actively unlocks the vehicle, the system sends a welcome signal. When the user leaves the welcome / farewell zone or actively locks the vehicle, the system sends a farewell signal. Based on the received welcome or farewell signals, and considering whether the current battery level is sufficient to activate the lighting effects (specifically, by receiving the SOC signal), the system controls the rear quarter window light assembly to execute the corresponding welcome or farewell lighting effects.

[0151] Welcoming and seeing off guests can be equivalently defined as:

[0152] Welcome: Areas A, B, and C light up simultaneously for 500ms, then turn off simultaneously for 500ms; then areas A, B, and C light up one by one in sequence, with an interval of 500ms, and turn off for 500ms after all are lit; finally, the current battery level is displayed for 1 second based on the SOC value detected by BDC.

[0153] Farewell: After areas A, B, and C light up simultaneously for 1 second, they turn off sequentially in the order of A, B, and C, with an interval of 500ms.

[0154] The welcome or farewell lighting effects are short-lived. After the welcome or farewell lighting effects are completed, the rear quarter window light assembly returns to its state before the welcome or farewell lighting effects were implemented. For example, if the lighting effect before the welcome or farewell lighting effects was in the charging / discharging mode, then after the welcome or farewell lighting effects are completed, the lighting effect corresponding to the charging / discharging mode will continue to be implemented.

[0155] By employing embodiments of this disclosure, the vehicle's lighting response is adjusted automatically based on the user's location and behavior, significantly enhancing the user experience through intelligent greeting and farewell mechanisms. In nighttime or low-light conditions, the automatic lighting greeting and farewell function provides users with better visibility and safety. The triggering of the lighting effects depends on the user's actual behavior and battery status, avoiding unnecessary energy waste. This lighting system enables the vehicle to respond to user actions, enhancing vehicle interactivity. The lighting control system can be adjusted according to different user habits and needs, such as setting different greeting and farewell zones or adjusting the sensitivity and type of lighting effects.

[0156] In one optional embodiment, controlling the rear quarter window light assembly to perform welcome lighting effects or farewell lighting effects includes: receiving a color signal that sets the color of the rear quarter window light assembly; the color signal carrying the set light color information; and responding to the color signal, controlling the rear quarter window light assembly to perform the welcome lighting effect or the farewell lighting effect according to the light color information carried by the color signal. The welcome and farewell lighting modes can be customized by the user via a soft switch for "Rear Quarter Window Welcome Light" in the vehicle's infotainment system. When this soft switch is enabled, a custom light color can be selected from 64 colors. The light color of the rear quarter window light assembly in welcome and farewell mode can be controlled by receiving a color signal HU_CPillarLampClrSts = 0x1 to 0x40 sent by the vehicle infotainment terminal assembly HU2 from the body controller assembly BDC7.

[0157] By employing embodiments of this disclosure, vehicles can more effectively attract passenger attention and provide visual guidance and a sense of welcome through colorful lighting displays. Different colored lights can evoke different emotional responses; warm tones like yellow or orange can create a friendly and welcoming atmosphere, while cool tones such as blue convey a sense of calm and elegance. Users can customize the lighting colors and modes via a mobile application or vehicle settings, providing a more personalized riding experience.

[0158] Figure 5 This is a flowchart illustrating a welcoming / farewell lighting control method according to an embodiment of this disclosure. Figure 5 As shown, the system first checks if HU_CPillarLampWelSts = 0x1 exists via BDC. If HU_CPillarLampWelSts = 0x1 does not exist, all lighting effects corresponding to the welcome / farewell mode are stopped. If HU_CPillarLampWelSts = 0x1 exists, the system checks if the welcome / farewell mode trigger conditions are met. If the welcome / farewell mode trigger conditions are met, the system checks if the battery SOC value is greater than 20% via BDC. If the battery SOC value is not greater than 20%, the low battery warning lighting effect is executed. If the battery SOC value is greater than 20%, the system controls the rear quarter window of the vehicle to execute the welcome / farewell lighting effect via BDC.

[0159] In one optional embodiment, the method further includes: acquiring a power signal; the power signal being used to characterize the current power level; and controlling the rear quarter window light assembly to perform a low power warning lighting effect when the current power level is lower than a first threshold.

[0160] The BDC7 body control assembly detects the battery's State of Charge (SOC) signal. If the detected PCU_SOC > 20%, it indicates that the vehicle is in low battery mode, and the rear quarter window light assembly is controlled to execute a low battery warning light effect. The low battery warning light effect can be defined as: the rear quarter window flashes orange to warn of low battery, with a flashing period of 500ms.

[0161] Depending on the specific percentage of remaining battery power, the flashing rate or brightness of the lights may be adjusted to more strongly convey the level of urgency.

[0162] By employing embodiments of this disclosure, a low battery warning light effect allows the vehicle to promptly notify the driver or surrounding personnel that the battery is low, preventing unexpected vehicle breakdown due to depletion of power. Through the lighting effect, the owner can intuitively understand the low battery situation without needing to check detailed data, facilitating timely charging or other appropriate measures. This intelligent battery management and warning system enhances the user's perception of the vehicle's battery status, making the driving experience safer and more convenient.

[0163] In one optional embodiment, receiving the lighting control signal corresponding to the lighting mode includes: collecting external vehicle data; identifying the external vehicle data to detect whether the vehicle is in an abnormal state; detecting whether the safety indicator switch is turned on; and, in response to the abnormal state, sending an abnormal warning signal when both the lighting effect switch and the safety indicator switch are turned on; and, when the target lighting control signal is the lighting control signal corresponding to the sentry mode, controlling the rear quarter window light assembly to execute the lighting effect corresponding to the target lighting control signal includes: in response to the abnormal warning signal, driving the external speaker to sound and controlling the rear quarter window light assembly to execute the warning lighting effect; in response to the abnormal state being resolved, sending an abnormality resolution signal; and in response to the abnormality resolution signal, stopping driving the external speaker to sound and stopping controlling the rear quarter window light assembly to execute the warning lighting effect.

[0164] Before implementing the lighting effects corresponding to Sentry Mode, it is necessary to check the Sentry Mode switch status. This soft switch can be defined as:

[0165] HU_SentryModeSts = 0x1 on (On)

[0166] HU_SentryModeSts=0x2 off(off)

[0167] When HU_SentryModeSts = 0x1 is detected, it indicates that the sentry mode is enabled; when HU_SentryModeSts = 0x2 is detected, it indicates that the sentry mode is disabled.

[0168] With Sentinel Mode enabled, external vehicle data is collected; this external data is then analyzed to detect if the vehicle is in an abnormal state. Specifically, the external vehicle data acquisition module DCM5 transmits the data to the Intelligent Driving Domain Controller (MDC6), which can then identify the abnormal state based on the collected data.

[0169] Synchronously detect whether the safety indicator switch is on. The safety indicator switch can be defined as: HU_CPillarLampSafeSts = 0x1 on (on);

[0170] HU_CPillarLampSafeSts=0x2 off (off).

[0171] When HU_CPillarLampSafeSts = 0x1 is detected, it indicates that the safety indicator switch is in the on state; when HU_CPillarLampSafeSts = 0x2 is detected, it indicates that the safety indicator switch is in the off state. When both the lighting switch and the safety indicator switch are on, an abnormality warning signal is sent in response to the abnormal state. Specifically, when the intelligent driving domain controller MDC6 recognizes an abnormal state, it sends an abnormality warning signal MDC_SentryAlert = 0x1 to the body domain controller BDC via the CAN bus.

[0172] In response to the aforementioned abnormal warning signal, the BDC7 body control assembly drives the exterior speakers to sound an alarm, and simultaneously drives the rear quarter window light assembly to execute corresponding lighting effects and color control. The specific scenario is defined as follows: Zones A, B, and C flash red simultaneously with the alarm sound, lighting up for 500ms and turning off for 300ms, repeating in a loop.

[0173] Upon resolution of the abnormal state, an abnormality clearance signal is sent. In response to the abnormality clearance signal, the external speaker buzzer is stopped, and the rear quarter window light assembly is stopped from performing warning lighting effects to warn surrounding pedestrians or vehicles. Specifically, when the intelligent driving domain controller MDC6 detects that the abnormal external state has been cleared, it sends an abnormality warning signal MDC_SentryAlert = 0x0 to the body domain controller BDC via the CAN bus. The BDC then stops driving the external speaker buzzer and the rear quarter window light assembly 9, and the rear quarter window light assembly 9 stops flashing, returning to the state before the sentry mode lighting effect was triggered.

[0174] By continuously collecting external vehicle data, such as information from cameras and sensors, the system can identify in real time whether the vehicle is in an abnormal state, greatly improving its safety capabilities. In an abnormal state, the system enhances the vehicle's visibility in emergencies through sentry mode light control signals and external speaker beeps, helping to quickly attract the attention of those around and reduce potential danger or damage. When the system detects that the abnormal state has been resolved, it sends an anomaly resolution signal. This signal activates the system, stopping the external speaker beeps and the rear quarter window warning lights, restoring normal operation. This intelligent control not only facilitates operation but also avoids unnecessary interference or panic. The system design integrates vehicle safety protection and information notification functions, enabling the vehicle to protect itself through visual and auditory signals in emergencies and notify the owner for timely action, thus improving overall vehicle safety and user experience.

[0175] Figure 6 This is a flowchart illustrating a sentry mode lighting control method according to an embodiment of this disclosure. Figure 6 As shown, the BDC detects whether the switch status signal is HU_SentryModeSts = 0x1 and HU_CPillarLampSafeSts = 0x1; when the switch status signal is HU_SentryModeSts = 0x1 and HU_CPillarLampSafeSts = 0x1, the BDC detects whether there is an abnormal status signal MDC_SentryAlert = 0x1 outside the vehicle; when there is an abnormal status signal MDC_SentryAlert = 0x1, the BDC drives the external speaker to sound and executes the warning light effect; the BDC detects whether there is a signal to clear the abnormal status outside the vehicle MDC_SentryAlert = 0x0; when there is a signal to clear the abnormal status outside the vehicle MDC_SentryAlert = 0x0, the BDC stops driving the external speaker to sound and the warning light effect.

[0176] Figure 7 This is a schematic diagram of the overall structure of a rear triangular window light according to an embodiment of the present disclosure; Figure 8 This is a schematic diagram of an exploded view of a rear triangular window light according to an embodiment of this disclosure; Figure 9 This is a schematic diagram illustrating the assembly of a rear quarter window light and surrounding components according to an embodiment of this disclosure. Figures 7-9 As shown, the rear triangular window light includes a sealing ring 11, a floating cover 12, a mask 13, a light-diffusing plate 14, a light guide block 15, a circuit board 16, a base 17, a sealing strip 18, a wiring harness assembly 19, a self-tapping screw 110, a fixing bracket 111, a fixing bracket 112, and double-sided adhesive tape 113.

[0177] Sealing ring 11: The sealing ring 11 is made of silicone and its main function is to provide waterproof and dustproof protection during the installation between the mask 13 and the suspension cover 12.

[0178] Floating cover 12: The floating cover 12 is made of semi-transparent, diffusing PC material and is produced by injection molding. This process can evenly disperse the light emitted by the LED light source 161, resulting in uniform light emission from the lampshade surface. The surface is treated with spray painting and laser engraving to create the light-transmitting area 121. The floating cover 12 is fixed to the face mask 13 by a snap-fit ​​structure, with two sealing rings 11 in between to prevent water leakage and dust ingress.

[0179] Face mask 13: The face mask 13 is made of transparent PC material and black PC / ABS dual-color injection molding to achieve a large area of ​​high gloss black appearance. Only a single layer of transparent PC material is used in some areas to achieve the visible area 132 and the part that needs to be lit. The inner surface of the part that needs to be lit is sprayed with paint and the shape texture is achieved by laser engraving process, that is, the light-transmitting area 131 of the panel, which can be changed according to the shape design.

[0180] Light-diffusing plate 14: The light-diffusing plate 14 is made of light-diffusing PC material, which can evenly disperse the light transmitted by the light guide block 15, so that the lampshade surface emits light uniformly. The light-diffusing plate 14 is positioned on the mask 13 by its own positioning structure. Light guide block 15: The light guide block 15 is made of colorless and transparent PMMA material, and is fixed to the mask 13 by injection molding process through its own snap-fit ​​structure, and fixes the light-diffusing plate 14 in the middle to the mask 13.

[0181] Circuit board 16: The circuit board 16 contains 19 LED light sources 161, which can generate multi-color light and adjust the light color and brightness according to control logic. Among them, 15 LED light sources correspond to the light guide block 15, and the other 4 LED light sources correspond to the floating cover 12. The circuit board 16 is fixed to the mask 13 by 6 self-tapping screws 110.

[0182] Base 17: The base 17 is made of black opaque PC / ABS material and mainly serves to protect the circuit board 16 and other components. The base 17 is fixed to the faceplate 13 by vibration friction welding.

[0183] Sealing strip 18: The sealing strip 18 is made of TPE material and is fixed to the face mask 13 by the positioning post structure of the face mask 13 itself and double-sided adhesive 113.

[0184] Wiring harness assembly 19: The wiring harness assembly 19 is soldered onto the circuit board 16 and is used to connect the circuit board 16 and the vehicle circuitry in series, supply power to the circuit board 16, and enable communication between the vehicle and the rear quarter window light 1 to transmit control signals. Fixing bracket 111: The fixing bracket 111 is made of stainless steel DC01 and is installed using six self-tapping screws 110 and a cover 13. It is used to fix the door sealing strip 4.

[0185] Fixed bracket 112: The fixed bracket 112 is made of stainless steel DC01 and is fixed by double-sided tape 113 and the positioning structure of the face mask 13 itself. It is used to limit the door decorative bright strip 5 and ensure the appearance difference with the rear quarter window light 1.

[0186] Double-sided adhesive 113: The double-sided adhesive 113 is VHB acrylic and is used to bond the sealing strip 18 to the face mask 13.

[0187] The rear quarter window light 1 is fixed to the side panel 2 via a snap-fit ​​structure on its own cover 13. The C-pillar snap-fit ​​sealing strip 4 is positioned by a fixing bracket 111, and the door decorative bright strip 5 is limited by a fixing bracket 112 to ensure that it has a different appearance from the rear quarter window light 1. The rear door outer trim assembly 3 has no direct connection with the rear quarter window light 1 and matches the lower side of the cover 13 in appearance.

[0188] The rear quarter window light 1 is connected in series with the vehicle via wiring harness assembly 19. The vehicle provides power to the rear quarter window light 1 and sends control signals to it. The 19 LED light sources 161 of the rear quarter window light 1 emit light of a specified color and brightness according to the control logic. The light generated by 15 of the LED light sources is conducted through light guide block 15, diffused through light diffuser plate 14, and then emitted through light-transmitting area 131 of mask 13; the light generated by the other 4 LED light sources is diffused through floating cover 12 and emitted from light-transmitting area 121.

[0189] The rear quarter window light 1's cover 13 can be laser-engraved to create different light-transmitting areas 131 according to the design, and the cover 13 achieves a visible area 132 through two-color injection molding. The cover 13, in conjunction with the floating cover 12, creates a floating light effect when the light-transmitting area 131 is illuminated. Additionally, the surface of the floating cover 12 can also be laser-engraved with light-transmitting areas 121 to achieve personalized lighting effects. In contrast, related technologies are based on the main glass of the quarter window, with the light source and optical components bonded to the center of the inner side of the main glass, while the outer surface remains a flat glass surface, limiting the overall design flexibility and increasing the cost of automotive glass. However, the rear quarter window light 1 of this invention provides a variety of different lighting effects, further enhancing the quality of the lighting and optimizing the user experience. Unlike existing designs with a flattened shape due to the glass main body of the quarter window, the rear quarter window light 1 of this invention uses injection-molded PC material for the entire quarter window body, facilitating more design features, increasing interior light transmittance, and enhancing the diversity of side lighting on the vehicle body.
