Abstract
Description
Technical Field
[0001] This application relates to the field of information display technology, and more specifically, to a method, apparatus, processor, and vehicle for displaying information on a vehicle. Background Technology
[0002] Currently, vehicle status information (such as charging progress, steering intention, and intelligent driving status) is mainly displayed through in-vehicle screens or terminal devices (Application, or APP). This requires users to actively view the information, resulting in a long interaction path, limited scenarios, and difficulty in real-time perception outside the vehicle, leading to poor intuitiveness. Especially at night or in long-distance scenarios, the delay in information acquisition affects user experience and safety. Therefore, the technical problem of poor intuitiveness in vehicle information display still exists.
[0003] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention

This eliminates the need for the user to actively operate the terminal or enter the vehicle, achieving immediate and intuitive information perception outside the vehicle. This directly avoids the display lag and unintuitive interaction caused by reliance on screens and apps in related technologies, thereby improving the intuitiveness of vehicle information display and solving the technical problem of poor intuitiveness in vehicle information display.

[0032] 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 skilled in the art without creative effort should fall within the scope of protection of the present application.
[0033] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0034] Figure 1 This is a schematic diagram illustrating an application scenario for displaying vehicle information according to an embodiment of this application, such as... Figure 1 As shown, the scenario described above may include terminal device 10, network 20, and vehicle 30. Terminal device 10 can be used to obtain confirmation instructions from the vehicle user (e.g., driver) regarding whether the vehicle needs flexible and intuitive information display. The terminal device can be a mobile phone, laptop, personal computer, or a vehicle. The confirmation instruction can be sent to vehicle 30 via network 20. At this point, vehicle 30 needs to execute steps S102 to S106 to realize the vehicle information display process.
[0035] The following steps can be performed by vehicle 30: Step S102, obtain the status information of each of the multiple functional modules in the vehicle; Step S104, map the status information to multiple light-emitting units in the vehicle's light-emitting trim according to the priority of the status information; Step S106, control the multiple light-emitting units to display the status information with the highest priority among the multiple status information according to the control strategy corresponding to the priority.
[0036] In this embodiment, through steps S102 to S106, the status information of multiple functional modules of the vehicle is directly mapped to multiple light-emitting units of the external light-emitting trim based on the priority defined by the importance of the functional modules to the driving and riding objects. The light-emitting parameters and on / off states (on or off) of each light-emitting unit are dynamically adjusted according to the control strategy corresponding to the priority. This allows the highest priority status information to be presented in real time on the exterior surface of the vehicle body with visible light effects, without requiring the user to actively operate the terminal or enter the vehicle. This enables immediate and intuitive information perception outside the vehicle, thereby directly avoiding the display lag and unintuitive interaction caused by the reliance on screens and apps in related technologies. This achieves the technical effect of improving the intuitiveness of vehicle information display and solves the technical problem of poor intuitiveness of vehicle information display.
[0037] According to an embodiment of this application, an embodiment of a vehicle information display method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0038] Figure 2 This is a flowchart of a vehicle information display method according to an embodiment of this application, such as... Figure 2 As shown, the method may include the following steps.
[0039] Step S202: Obtain the status information of each of the multiple functional modules in the vehicle.
[0040] In the technical solution provided in step S202 of this application, the status information can be used to represent the operating status of the functional module, and / or the interaction status between the vehicle's driver / passenger and the functional module.
[0041] Optionally, a functional module can refer to a subsystem in the vehicle with independent state output capabilities, used to generate signals related to vehicle operation or user interaction. The aforementioned functional modules may include, but are not limited to: a charging module, a steering module, an intelligent driving system module, a welcome sensor module, and a vehicle location module, whose function is to provide the raw state data source for information display. It should be noted that the above functional modules are merely illustrative examples and are not specifically limited here. Any functional module that can utilize the luminous decorative element of this application for information display is within the protection scope of the embodiments of this application.
[0042] Optionally, the aforementioned status information may refer to quantified or event-based data output by the functional module, representing the current operating status of the functional module or its interaction with the driver / passenger. This status information may include charging progress, steering command triggering, intelligent driving activation, welcome sensor recognition, vehicle location command reception, etc., reflecting the real-time operating context of the vehicle or the user's intent. It should be noted that the aforementioned status information is merely illustrative and not specifically limited here. Any status information that can be displayed using the luminous decorative element of this application is within the protection scope of this application's embodiments.
[0043] Optionally, the aforementioned operating states can refer to the internal working conditions of functional modules during vehicle operation, such as the charging percentage of the charging module, the on / off status of the steering module, and the activation or deactivation of the intelligent driving module, used to describe the technical behavior of the module itself. The aforementioned interaction states can refer to the active or passive response behaviors of the driving or passenger objects to the functional modules through physical or remote means, such as the welcome sensor module sensing the approach of the key, or the vehicle-finding module receiving instructions from a mobile app, used to characterize the behavioral association between the user and the vehicle. Here, the aforementioned driving or passenger objects can refer to the users or occupants of the vehicle, including the driver, passengers, or authorized associated users. The behavior or identity of the driving or passenger objects can trigger state changes in the functional modules, serving as the intention source for generating state information.
[0044] In this embodiment, if vehicle information needs to be displayed, the status information of multiple functional modules within the vehicle can be acquired. This embodiment constructs a multi-source status perception input by collecting the status information of multiple functional modules in real time, combining their operational status with the interaction status of the driver and passengers, thus providing precise and hierarchical decision-making basis for the subsequent dynamic control of the luminous decorative elements. This process does not rely on active user operation; instead, the vehicle system automatically senses and aggregates key status signals, achieving automation and systematization of information acquisition.
[0045] Optionally, the acquisition of status information for multiple functional modules within the vehicle can be achieved through communication links between each functional module and the vehicle domain controller. The charging module's status information is periodically transmitted by the battery management system via the Controller Area Network (CAN) bus, including numerical and event-based data such as current charging percentage, charging current, and charging status (e.g., charging, fully charged, abnormal interruption). The steering module's status information is acquired by the turn signal switch signal via the body control unit and output in the form of switch status and trigger timing, used to identify left turn, right turn, or hazard light commands. The welcome module's status information is triggered by a Bluetooth Low Energy or Radio Frequency Identification (RFID) sensing system detecting when a key or bound mobile phone enters a preset range, outputting a "Welcome Activation" event signal. The intelligent driving system module's status information is output through the autonomous driving domain controller, using binary states such as "Activated" or "Exited" to indicate whether it is currently in assisted driving or autonomous driving mode. The vehicle search function module's status information is received by the remote information processing unit from the mobile app, converted into a CAN signal, and outputs a "Vehicle Search Request" event, triggering a response mechanism.
[0046] It should be noted that the acquisition of the aforementioned status information in this embodiment can be based on the vehicle's internal communication architecture, with each functional module acting as an independent signal source and actively reporting, without manual intervention, thus ensuring the real-time, accuracy, and completeness of the information acquisition. This mechanism enables comprehensive perception of the vehicle's multi-dimensional operational and interactive states, laying a reliable data foundation for subsequent priority-based lighting control.
[0047] Step S204: According to the priority of the status information, map the status information to multiple light-emitting units in the vehicle's light-emitting trim.
[0048] In the technical solution provided in step S204 of this application, priority can be used to indicate the importance of the status information to be displayed to the driver and passengers. The aforementioned priority can refer to a preset relative importance ranking rule for different vehicle status information, used to determine which of the multiple status information events should be visually presented first through the luminous decorative element. In the embodiments of this application, the setting of the aforementioned priority can be based on the principles of safety and interaction necessity, directly related to the driving safety and critical operation response needs of the driver and passengers.
[0049] For example, turn signals are given the highest priority due to their impact on the safety of other road users; intelligent driving activation is given the next highest priority because it affects the expected behavior of the surrounding environment; intelligent welcome, charging progress, and vehicle location prompts are given decreasing priority in descending order of frequency and urgency. Priority is a static configuration parameter stored in the domain controller and cannot be dynamically modified, ensuring the determinism and consistency of the control logic. This priority mechanism ensures that high-risk status information always receives the highest display priority, preventing low-priority information from interfering with critical driving signals, thus achieving orderly and safe information display.
[0050] Optionally, the aforementioned luminous trim pieces can refer to independent components integrated into the vehicle's exterior structure, possessing dynamic light-emitting display functions, used to convey vehicle status information in the form of light effects when lighting is not required. The deployment location of the aforementioned luminous trim pieces can be optimized according to functional scenarios. For example, the deployment locations of the aforementioned luminous trim pieces may include, but are not limited to: the vehicle logo area (which can be used for intelligent welcome and intelligent driving status prompts), the front grille or fender trim (for turn signals and charging progress display), the rear continuous trim (for charging completion reminders and vehicle location prompts), and the B-pillar or lower rear window area (for high-priority safety prompts). The luminous trim pieces are integrally molded with the vehicle body, and in the non-illuminated state, they are consistent with the color and texture of the vehicle body paint, achieving visual concealment. They only display preset patterns or light effects when powered on, combining decoration, functionality, and safety.
[0051] It should be noted that the deployment positions of the light-emitting decorative elements in the embodiments of this application are merely illustrative examples and are not specifically limited here. Any position that can be set according to the function to be achieved and the information to be displayed is within the protection scope of the embodiments of this application.
[0052] Optionally, the light-emitting unit in the aforementioned luminous trim can refer to the basic controllable light-emitting element constituting the luminous trim. This can be an independently set light-emitting diode (LED) chip, LED segment, or OLED light-emitting area. Each light-emitting unit can be individually addressed and driven to construct continuous or segmented light effect patterns. In the embodiments of this application, the light-emitting units can be arranged in a linear, circular, or regional array according to spatial location and functional requirements. For example, the charging progress display uses 20 LED light strips distributed along the rear trim, each segment being a light-emitting unit; the welcome function uses multiple light-emitting units independently divided into the central area of the car logo and the strip areas on both sides, controlling the breathing and flowing effects respectively. As the physical output carrier of status information, the brightness, color, timing, and illumination range of the light-emitting unit are precisely controlled by the control strategy to achieve the visual expression of information.
[0053] In this embodiment, after acquiring the status information of multiple functional modules in the vehicle, the status information can be mapped to multiple light-emitting units in the vehicle's luminous trim according to the priority of the status information. Based on a preset status information priority rule, this embodiment accurately maps the real-time status information output by multiple functional modules of the vehicle to multiple light-emitting units in the luminous trim, realizing the priority display and visual occupancy of high-priority status information, ensuring that key information is not obscured or delayed in multi-state concurrent scenarios, and completing the intelligent decision-making process from data input to physical light effect output.
[0054] Optionally, the process of mapping state information to multiple light-emitting units in the vehicle's illuminated trim according to the priority of the state information can be achieved through logical judgment and spatial mapping operations performed by the domain controller. After receiving state information from various functional modules, the domain controller can compare the priority sequence of each state information. This sequence is fixed during system initialization as follows: turn signal prompt > intelligent driving prompt > intelligent welcome > charging progress display > vehicle location prompt. When multiple state information is triggered simultaneously, the domain controller retains only the highest priority state information and disables the output requests of the remaining lower priority information. Based on the type of the high-priority state information, the domain controller calls a preset illumination mode library to determine the corresponding light-emitting unit activation range, brightness level, color parameters, and dynamic timing. For example, when the turn signal prompt is triggered, the domain controller activates the continuous light-emitting units in the rear trim strip near the turn signal side as a yellow flowing effect, with the illumination direction of the light-emitting units corresponding to the turn signal. Figure 1To ensure completeness and directionality of information delivery, the illuminated length matches the physical length of the trim strip. When an intelligent driving prompt is triggered, the domain controller activates only the ring-shaped luminous unit in the logo area, outputting a blue ring-shaped flowing light effect, while the luminous units in other areas remain off to avoid interference. If there are no higher-priority conflicting information, the charging progress information is linearly mapped from 0% to 100% to the 20 luminous units on the rear trim strip, with the number of illuminated segments proportional to the progress, forming an intuitive light column.
[0055] In this embodiment, the mapping process achieves semantic binding and spatial adaptation between state information and light-emitting units, ensuring that each type of state information is unique, clear, and unambiguous in visual expression. Simultaneously, a priority mechanism prevents low-value information from interfering with critical safety information. This mechanism enhances the reliability and security of information transmission, enabling drivers and passengers to always receive the highest-priority visual cues in complex driving environments, significantly improving the intuitiveness and responsiveness of human-vehicle interaction.
[0056] Step S206: According to the control strategy corresponding to the priority, control multiple light-emitting units to display the status information with the highest priority among multiple status information.
[0057] In the technical solution of step S206 of this application, the control strategy is used to represent the luminous parameters of multiple luminous units and the rules for turning them on or off. The control strategy can refer to a set of predefined logical instructions for each state information, used to drive multiple luminous units in the luminous trim to perform visual expression. The content includes the on / off sequence, lighting order, dynamic effect form, and duration of the luminous units. The control strategy is customized based on the semantic characteristics and interaction purpose of the state information. For example, the control strategy for turn signal prompts is defined as "the luminous units on one side gradually brighten from the inside out, forming a flowing effect consistent with the turning direction, with the flashing frequency synchronized with the vehicle's turn signals"; the control strategy for intelligent welcome is defined as "the luminous units in the car logo area slowly dim in a periodic breathing mode, followed by the luminous units on both sides of the trim lighting sequentially from the center to both ends"; the control strategy for charging progress is defined as "linearly activating the corresponding number of luminous units according to a percentage, with new lighting segments accompanied by brief high-brightness flashes to enhance progress perception." The control strategy is a software logic module embedded in the domain controller, and its execution is not subject to user intervention, ensuring the consistency, accuracy, and safety of the light effect expression in different scenarios.
[0058] Optionally, the aforementioned luminescence parameters can refer to quantifiable physical attributes used to regulate the visual output of each luminescence unit, including brightness intensity, color wavelength, illumination duration, rate of change, and switching response time. Brightness intensity determines the visibility of the light effect in daytime or nighttime environments, and can be set to a relative output value from 0% to 100%. High-priority states, such as turn signals, use the highest brightness to ensure visibility. Color wavelength is used to distinguish information categories, such as yellow (590nm) for turn signals, blue (470nm) for intelligent driving prompts, and white (6500K) for charging completion. Illumination duration and rate of change define the rhythm of dynamic effects, such as a 2-second cycle for a breathing effect and a 100-millisecond delay for a flowing effect. Switching response time controls the start-stop delay of the luminescence unit, ensuring seamless state transitions. The luminescence parameters and control strategies work together to form a complete visual language system for the luminescence decoration to convey information. Their numerical ranges are determined through ambient light testing and human factor assessment, meeting regulatory visibility requirements and user experience consistency.
[0059] In this embodiment, after mapping the highest-priority state information to multiple light-emitting units of the luminous trim according to the priority of the state information, the multiple light-emitting units can be controlled to display the highest-priority state information according to the control strategy corresponding to the priority. This embodiment uses priority determination as the trigger premise and a preset control strategy as the execution basis to implement precise light-emitting unit driving control for the highest-priority state information among multiple state information, ensuring that the vehicle only presents the highest-priority visual cues in multi-task concurrent scenarios, thereby achieving the orderliness, security, and consistency of information display.
[0060] Optionally, during the process of controlling multiple luminous units to display the status information according to the highest priority status information, the vehicle domain controller can perform a complete process of logical filtering and strategy invocation according to a preset priority sequence after receiving multi-source status signals in real time. The domain controller first synchronously collects status information from the battery management system, turn signal switch, intelligent driving domain controller, Bluetooth key sensing module, and remote information processing unit, and compares the priority of each piece of information. The priority sequence is fixed as follows: turn signal prompt > intelligent driving prompt > intelligent welcome > charging progress display > vehicle location prompt. When multiple status information is detected to be triggered simultaneously, the domain controller selects only the status information with the highest priority. The display requests of the other lower priority information are immediately blocked and do not participate in the subsequent light effect generation. After selecting the highest priority status information, the domain controller calls the matching dedicated control strategy from the built-in control strategy library. This strategy includes the on / off timing of the luminous units, the lighting order, the brightness change curve, the color setting, and the dynamic effect mode.
[0061] For example, when the turn signal is determined to be the highest priority, the domain controller activates the continuous light-emitting unit located in the rear trim strip near the turn signal side. Following a control strategy of "gradually brightening from the inside out, with a delay of 100 milliseconds per segment, and a continuous flashing frequency synchronized with the turn signal at 1.5Hz," it outputs a yellow flowing light effect. When the intelligent driving prompt is the highest priority, the domain controller only activates the ring-shaped light-emitting unit in the vehicle logo area, employing a control strategy of "slow, continuous, blue light with a 3-second cycle and 70% brightness," while the light-emitting units in other areas remain off. The entire control process does not rely on manual intervention; all parameters are executed based on preset system logic, ensuring consistent response and reliable execution.
[0062] In this embodiment, the method described above achieves precise focusing of visual information and safety priority in complex driving scenarios through a dual mechanism of priority-driven and control strategy binding, effectively avoiding visual confusion and information overload caused by the superposition of multiple states. This method not only improves the recognition efficiency of key driving safety information but also ensures the clarity and immediacy of the user's perception of the vehicle's status, significantly enhancing the intelligence and safety of human-vehicle interaction.
[0063] In steps S202 to S206 of this application, if vehicle information display is required, the status information of multiple functional modules in the vehicle can be obtained. The priority of each status information can be determined, and the highest priority status information is mapped to multiple light-emitting units in the vehicle's luminous trim. The control strategy corresponding to the highest priority status information can be used to control the multiple light-emitting units to display the highest priority status information. In other words, in this embodiment, by directly mapping the status information of multiple functional modules of the vehicle to multiple light-emitting units of the vehicle's external luminous trim based on the priority defined by the importance of the functional modules to the driver and passengers, and dynamically adjusting the light-emitting parameters and on / off states (open or closed) of each light-emitting unit according to the priority-corresponding control strategy, the highest priority status information is presented in real-time on the vehicle's exterior surface with visible light effects. This eliminates the need for the user to actively operate the terminal or enter the vehicle, achieving immediate and intuitive information perception outside the vehicle. This directly avoids the display lag and unintuitive interaction caused by reliance on screens and apps in related technologies, thereby improving the intuitiveness of vehicle information display and solving the technical problem of poor intuitiveness in vehicle information display.
[0064] The method described in this embodiment will be further described below.
[0065] As an optional embodiment, step S204, mapping the state information to multiple light-emitting units in the light-emitting decorative element according to the priority of the state information, includes: determining the mapping relationship between the state information with the highest priority among the multiple state information and the multiple light-emitting units; and mapping the state information with the highest priority to the multiple light-emitting units according to the mapping relationship.
[0066] In this embodiment, during the process of mapping state information to multiple light-emitting units of the luminous trim according to the priority of state information, the mapping relationship between the highest priority state information and the light-emitting unit can be determined from multiple state information. The highest priority state information can be mapped to multiple light-emitting units according to the above mapping relationship. Here, the above mapping relationship refers to a deterministic mapping rule based on semantic and physical space correspondence established between vehicle state information and multiple light-emitting units in the luminous trim. Essentially, it is a pre-defined, immutable functional logic used to transform abstract state information into a concrete expression of light effects. The mapping relationship takes the type of state information as input and outputs the number of lit light-emitting units, their positional distribution, brightness gradient, color attributes, and dynamic timing, achieving a precise conversion from system signals to visual presentation.
[0067] For example, the mapping relationship between charging progress status information and the light-emitting units is defined as follows: the battery percentage from 0% to 100% linearly corresponds to the number of segments lit sequentially among the 20 light-emitting units. Each 5% increase in battery power illuminates one light-emitting unit, and the newly illuminated segment briefly flashes at 1.5 times the brightness upon activation, providing clear progress feedback. If the light-emitting trim includes a trim on the left side of the vehicle (e.g., deployed on the left rear window) and a trim on the right side (e.g., deployed on the right rear window), the mapping relationship between the turn signal status information and the light-emitting units is defined as follows: when a left turn signal is triggered, the continuous light-emitting units in the aforementioned left-side trim are activated from the inside (e.g., the front of the vehicle) to the outside (e.g., the rear of the vehicle), forming a light band flowing to the left. If a right turn signal is triggered, the continuous light-emitting units in the aforementioned right-side trim are activated from the inside to the outside, forming a light band flowing to the right. Through the above mapping relationship between the turn signal status information and the light-emitting units, it can be ensured that the direction of the light effect corresponds to the turn signal. Figure 1 The mapping relationship is contained in the control policy library of the domain controller. Each state information corresponds to a unique and independent mapping function. Its parameters are solidified after environmental visibility testing, human factors engineering assessment, and regulatory compliance verification, ensuring that the light effect expression of different vehicles, different users, and different environments has a high degree of consistency and predictability. This mapping relationship is the core mechanism for realizing "one set of hardware, multiple scenarios reuse" and is also the basic logical support for ensuring the accuracy and security of information transmission.
[0068] Optionally, the process of determining the mapping relationship between the highest priority state information and multiple light-emitting units among multiple state information can be completed by the domain controller during the initialization phase or system upgrade, based on a pre-configured static logic library according to functional safety specifications and human factors design principles. This mapping relationship is a one-to-one, type-specific function definition. Each state information—such as turn signal indication, intelligent driving activation, charging progress, intelligent welcome, or vehicle location indication—is assigned a unique corresponding light-emitting unit control template. For example, the mapping relationship for turn signal indication is defined as "activating only the continuous light-emitting units in the rear trim corresponding to the turning direction, illuminating them in a flowing manner from the inside out, with a brightness of 100%, a yellow color, and a flashing frequency synchronized with the turn signal"; the mapping relationship for charging progress is defined as "linearly distributing the charge from 0–100% to 20 light-emitting units, with the number of illuminated segments proportional to the progress, and triggering a 1.5 times brightness pulse the moment a newly activated unit is illuminated"; the mapping relationship for intelligent driving indication is defined as "activating only the ring-shaped light-emitting unit in the vehicle logo area, outputting a slow-flowing blue ring light effect with a period of 3 seconds." These mapping relationships do not rely on runtime dynamic calculations, but are permanently stored in the domain controller's non-volatile memory, ensuring that they can be quickly and stably invoked under any operating conditions, and are fully compatible with the hardware structure, avoiding light effect misalignment or information ambiguity caused by parameter deviations.
[0069] Optionally, during the process of mapping the highest priority status information to multiple light-emitting units according to the above mapping relationship, when multiple status information is triggered simultaneously, the domain controller first determines the current highest priority status information based on the preset priority sequence: turn signal prompt > intelligent driving prompt > intelligent welcome > charging progress display > vehicle location prompt. Subsequently, the domain controller locks the identity identifier corresponding to the status information, extracts its exclusive control template from the mapping relationship library, and converts the instructions in the template, such as the position of the light-emitting unit, brightness level, color parameters, and timing rhythm, into specific drive signals and sends them to the LED driver chip of the light source module. For example, when the turn signal prompt is determined to be the highest priority, the system immediately disables the currently executing charging progress display and activates the eight consecutive light-emitting units on the right side of the rear trim strip, lighting them up segment by segment at 100-millisecond intervals to form a yellow light band flowing to the right; if the turn signal disappears at this time, the domain controller restores the mapping relationship corresponding to the previous lower priority state (such as charging progress) and continues to light up the light-emitting units according to the power ratio. This process is without manual intervention, signal conflict, and delayed switching, ensuring that the light effect response is completely synchronized with the changes in vehicle status.
[0070] In this embodiment, the method described above achieves accurate, safe, and unambiguous visual representation of vehicle status information on luminous trim pieces through a collaborative mechanism of priority-driven and preset mapping relationships. This effectively avoids visual interference and information confusion when multiple pieces of information are displayed concurrently, significantly improving driving safety and the clarity of human-machine interaction. This method not only ensures the priority transmission of critical driving information but also achieves a reusable, verifiable, and scalable software architecture through standardized mapping rules, providing a reliable and efficient technical foundation for intelligent vehicle exterior interaction.
[0071] As an optional embodiment, according to the mapping relationship, the highest priority state information is mapped to multiple light-emitting units, including: in response to the highest priority state information being the charging progress of charging using the charging module in the vehicle, the charging progress is mapped to at least one target light-emitting unit among the multiple light-emitting units according to the mapping relationship between the charging progress and the multiple light-emitting units, wherein the number of target light-emitting units is positively correlated with the charging progress.
[0072] In this embodiment, during the process of mapping the highest priority state information to multiple light-emitting units according to the mapping relationship, if the highest priority state information is the charging progress using the vehicle's charging module, the charging progress can be mapped to at least one target light-emitting unit among the multiple light-emitting units according to the mapping relationship between the charging progress and the multiple light-emitting units. The aforementioned charging module refers to a system unit in the vehicle used to realize the input, management, and control of electrical energy from external charging equipment to the power battery. Its functions include receiving power supply signals from the charging pile, adjusting charging current and voltage, monitoring the battery's state of charge (SOC), communication interaction, and safety protection. It is a core execution component for energy replenishment in new energy vehicles. The charging module is typically integrated into the vehicle's power management system and interacts with the Battery Management System (BMS), domain controllers, and other units via the CAN bus to provide accurate quantitative output of the vehicle's charging status. This module does not directly participate in light effect generation, but as the original data source for charging progress information, it is a necessary input source for the light-emitting trim to realize the visualization function of external charging.
[0073] Optionally, the aforementioned charging progress can refer to a quantitative value, calculated and output by the charging module and the battery management system, characterizing the current charging completion level of the power battery. This value ranges from 0% to 100%, reflecting the real-time state evolution of the battery from idle to fully charged in percentage form. The charging progress is a periodically updated dynamic parameter; its numerical changes directly reflect the continuity and efficiency of the charging process, serving as crucial information for users to judge the charging status and plan their trips. In this invention, the charging progress, as a type of state information with clear time evolution characteristics, is assigned specific visual expression rules to drive the light-emitting units in the luminous trim to appear in a linear proportion, achieving non-contact, intuitive charging status perception outside the vehicle.
[0074] Optionally, the target light-emitting unit can refer to several independent, controllable light-emitting units in the light-emitting trim that are activated according to the mapping relationship of charging progress and used to express the charging progress. The number is positively correlated with the percentage of charging progress, that is, the higher the charging progress, the more target light-emitting units are lit. The target light-emitting unit can be an LED segment evenly distributed along a specific geometric path (such as a longitudinal strip, ring, or rear window edge) within the light source module. Its physical position is precisely aligned with the light-transmitting pattern area on the decorative functional film layer to ensure that the light effect is integrated with the body design.
[0075] For example, when the charging progress is 65%, 13 out of the 20 light-emitting units are identified as target light-emitting units and are lit up, forming a continuous light column pattern; when charging is complete, all light-emitting units are target light-emitting units, achieving full-scale lighting. The target light-emitting units do not include light-emitting units used for other status information (such as turning, welcoming), and their activation is triggered only by the charging progress mapping relationship, ensuring the specificity and accuracy of information expression.
[0076] Optionally, in response to the highest priority status information, charging progress, the domain controller first obtains the real-time state of charge (SOC) value from the battery management system. This value is in percentage form, ranging from 0% to 100%, and is collected and periodically updated by the charging module and the battery management system. The domain controller uses this value as input and calls a preset charging progress mapping relationship. This mapping relationship is a linear function defined as follows: every 1% of charging progress corresponds to the activation of one light-emitting unit, and the total number of light-emitting units is fixed at 20 segments, evenly distributed in the rear trim or logo area of the vehicle. When the charging progress is 30%, the system activates the first 3 light-emitting units; when the charging progress is 78%, the system activates the first 78%, or 15.6 segments. Since the light-emitting units are discrete physical units, the system uses rounding down and a dynamic compensation mechanism, i.e., illuminating 15 complete units and activating the 16th unit with 50% brightness to achieve a smoother visual transition. Among all target light-emitting units, the newly lit unit triggers a momentary high-brightness pulse upon activation, increasing brightness to 1.5 times the standard brightness for 200 milliseconds, creating visual feedback of "progress" and enhancing user perception. The mapping process of charging progress does not rely on external intervention; it is automatically executed by the domain controller based on a fixed algorithm, ensuring consistent response and system stability.
[0077] Optionally, the activation of the target luminous units follows a strict physical spatial sequence, starting with the first segment near the center of the vehicle and illuminating each segment sequentially towards both ends along the trim strip, forming a linear light column from low battery to high battery. This sequence aligns with the user's cognitive habit of "from low to full," reducing the cognitive load. The illumination state of the luminous units does not include any other functional light effects that may interfere, such as turn signals or welcoming breathing patterns, ensuring that the charging information is visually independent and exclusive. Upon completion of charging, all 20 target luminous units are constantly illuminated at full brightness, and the system enters a "celebration mode," which involves three synchronized breathing flashes at a frequency of 1Hz, followed by continuous illumination, clearly conveying the charging completion signal. When the charging end signal is triggered, the system gradually dims all target luminous units after a 30-second delay, returning to a completely concealed state.
[0078] In this embodiment, the method described above achieves efficient conversion of charging status from internal vehicle system data to external public visual language through a linear, ordered, and perceptible mapping mechanism between charging progress and target light-emitting units. This method eliminates users' reliance on querying charging status, enhances the transparency and technological feel of the charging process, and ensures consistent experience across different vehicle models and user scenarios through standardized and reusable mapping rules, significantly improving the interactive intelligence and user satisfaction of new energy vehicles in public spaces.
[0079] As an optional embodiment, determining the mapping relationship between the highest priority state information among multiple state information and multiple light-emitting units includes: determining the highest priority state information from multiple state information according to a preset priority order, wherein the preset priority order is used to indicate the order of priority among multiple state information; and retrieving the mapping relationship between the highest priority state information and multiple light-emitting units from the mapping database.
[0080] In this embodiment, during the process of determining the mapping relationship between the highest priority state information and multiple light-emitting units among multiple state information, the highest priority state information can be determined from the multiple state information according to a preset priority order. The mapping relationship between the highest priority state information and multiple light-emitting units can be retrieved from the mapping database. The preset priority order can refer to a logical sequence fixed in the domain controller during system initialization, used to determine the importance level of multiple vehicle state information. It defines a clear priority relationship between state information such as turn signals, intelligent driving signals, intelligent welcome, charging progress display, and vehicle location signals, ensuring that only the highest priority information is allowed to output light effects when multiple information is concurrent. This order is set according to driving safety regulations and human factors engineering principles, and has non-overridability and enforceability, serving as the core mechanism for prioritizing the transmission of safety information. The mapping database can refer to a set of correspondences between multiple state information and light-emitting unit control parameters stored in the non-volatile storage unit of the domain controller. Each state information corresponds to a unique and specific mapping rule, including the number of activated light-emitting units, their position distribution, brightness, color, and dynamic timing. This database is a static configuration library and is not dynamically modified during runtime, ensuring the stability and consistency of the light effect expression.
[0081] Optionally, in determining the highest priority state information from multiple state information according to a preset priority order, the process can be a logical filtering process executed by the domain controller after receiving status signals in real time from the battery management system, intelligent driving domain, steering signal module, Bluetooth key sensing unit, and telematics unit. The preset priority order is a fixed and unchangeable hierarchical sequence defined as follows: steering prompts have the highest priority, followed by intelligent driving prompts, then intelligent welcome, charging progress display, and vehicle location prompts. The domain controller compares all triggered state information level by level in this sequence from high to low. Once a state information is detected with a priority higher than all subsequent states, it is determined to be the highest priority state information, and the display requests of other lower priority information are immediately suppressed and do not participate in subsequent processing. This determination process is an atomic operation with a response time of less than 10 milliseconds, ensuring no race conditions or information omissions when multiple signals arrive simultaneously.
[0082] Optionally, during the process of retrieving the mapping relationship between the highest priority status information and multiple light-emitting units from the mapping database, a resource configuration action is executed immediately after the highest priority status information is determined. The mapping database is a pre-built static dataset in the domain controller. Each entry corresponds to a type of status information and a set of precise light-emitting unit control parameters, including the location number of the illuminated unit, brightness level, color wavelength, dynamic timing, and flashing frequency. For example, when the highest priority status information is determined to be "turning prompt", the domain controller retrieves the "turning prompt - light-emitting unit mapping" entry to obtain a complete set of control instructions: "activate only the corresponding side trim continuous light-emitting units, illuminate in a flowing pattern from the inside out, yellow, frequency 1.5Hz"; when the highest priority is "charging progress", the "charging progress - light-emitting unit mapping" entry is retrieved to obtain the rules: "linearly illuminate the target unit, pulse enhancement of the new illuminated segment, brightness ratio corresponding to SOC value". This mapping relationship is a one-to-one binding, does not rely on runtime calculation, and ensures strict alignment between light effect output and status semantics.
[0083] In this embodiment, the method described above achieves ordered output of visual information in multi-task scenarios through forced prioritization and precise indexing of the mapping database, completely avoiding user cognitive confusion and safety hazards caused by the superposition of multiple lighting effects. This mechanism not only ensures the timely, unique, and clear transmission of key driving information, but also enhances system maintainability and functional scalability through a standardized and verifiable mapping structure, providing a safe, reliable, and efficient technical foundation for intelligent vehicle exterior interaction.
[0084] As an optional embodiment, step S206 involves controlling multiple light-emitting units to display the highest priority status information among multiple status information according to the control strategy corresponding to the priority. This includes: responding to the highest priority status information being the charging progress of charging using the charging module in the vehicle, controlling multiple light-emitting unit segments composed of multiple light-emitting units respectively according to the control strategy corresponding to the charging progress to display the charging progress, wherein the light-emitting unit segment is composed of multiple adjacent light-emitting units.
[0085] In this embodiment, during the process of controlling multiple light-emitting units to display the highest priority status information according to the priority-corresponding control strategy, if the highest priority status information is charging progress, the multiple light-emitting unit segments composed of multiple light-emitting units can be controlled separately according to the control strategy corresponding to the charging progress to display the charging progress. Here, a light-emitting unit segment refers to a light-emitting area unit composed of multiple adjacent light-emitting units arranged in a preset spatial order, which can be uniformly controlled. It serves as the basic control unit for achieving gradual and continuous light effect display in the light-emitting decorative element. Each light-emitting unit segment corresponds to the visual expression of a certain interval in the charging progress. For example, a light-emitting unit segment can contain 3 to 5 consecutive light-emitting units to jointly present the incremental change in charging progress, avoiding visual jumps caused by single-point lighting. This structure makes the light effect presentation closer to a linear light column or dynamic strip, improving the user's continuous perception and spatial understanding of the charging status, and is the physical basis for realizing a "progress bar" visual display. The division of the light-emitting unit segments and the layout of the light-transmitting pattern of the decorative functional film layer are strictly aligned to ensure clear light effect boundaries and no scattering interference.
[0086] Optionally, in response to the highest priority status information, which is the charging progress, the domain controller allocates the charging progress percentage value proportionally to multiple light-emitting unit segments according to a preset charging progress control strategy, with each light-emitting unit segment corresponding to a fixed power range.
[0087] For example, when the illuminated trim consists of ten light-emitting unit segments, each segment containing two light-emitting units, for a total of twenty light-emitting units, each 10% charging progress corresponds to the activation of one light-emitting unit segment. When the charging progress reaches 45%, the system controls the first four light-emitting unit segments to be fully illuminated, and the fifth light-emitting unit segment adjusts its brightness according to the remaining 5%, that is, it illuminates all its internal light-emitting units at 50% brightness, achieving a fine expression of non-full segment illumination. The illumination of each light-emitting unit segment follows a spatial sequence, starting from the first segment near the center of the vehicle and expanding outwards to both ends, forming a linear light column from low to high, consistent with the user's cognitive logic of "battery charge increasing from low to high". At the moment each light-emitting unit segment is activated, all its internal light-emitting units simultaneously trigger an instantaneous brightness enhancement, with an enhancement magnitude of 1.5 times the standard brightness, lasting for 200 milliseconds, as a dynamic feedback signal to enhance the perceived experience of "progress". All control commands are sent directly from the domain controller to the corresponding drive channel of the light-emitting unit segment, ensuring that each segment responds synchronously, without delay or interference, and without interfering with the light effect of other status information.
[0088] In this embodiment, the method described above achieves a continuous, smooth, and quantifiable expression of charging progress in visual space through a segmented fine-tuning mechanism using light-emitting unit segments as control units. This significantly improves the user's perception accuracy and interactive experience of charging status outside the vehicle. This approach overcomes the abruptness and information ambiguity caused by single-point illumination. Furthermore, through the collaborative design of spatial sequence and dynamic feedback, the light effect conforms to human cognitive patterns while also possessing engineering feasibility, providing a technical solution for new energy vehicle exterior interaction that combines functionality, safety, and aesthetic unity.
[0089] As an optional embodiment, in response to the highest priority state information being the charging progress using the charging module in the vehicle, the multiple light-emitting unit segments composed of multiple light-emitting units are controlled according to the control strategy corresponding to the charging progress to display the charging progress, including at least one of the following: in response to the charging progress indicating that the vehicle's battery level is in a first battery level range, the first light-emitting unit segment among the multiple light-emitting unit segments is controlled to be in an "on" state with a first light-emitting parameter, according to the control strategy; in response to the charging progress indicating that the battery level rises from the first battery level range to a second battery level range, the second light-emitting unit segment among the multiple light-emitting unit segments is controlled to be in an "on" state with a second light-emitting parameter, according to the control strategy, within a first target duration, and after the first target duration, the second light-emitting unit segment is controlled to be in an "on" state with a second light-emitting parameter, and after the first target duration, the second light-emitting unit segment is controlled to be in an "on" state with a second light-emitting parameter, according to the control strategy. The first and second light-emitting unit segments are in the "on" state of the first light-emitting parameter, wherein the second light-emitting parameter is greater than the first light-emitting parameter. The second light-emitting unit segment is adjacent to the first light-emitting unit segment and is located behind the first light-emitting unit segment. In response to the charging progress indicator that the battery is fully charged, according to the control strategy, within a second target duration, the multiple light-emitting unit segments are controlled to be in a flashing state at a preset frequency, and after the second target duration, the multiple light-emitting unit segments are controlled to be in the "on" state of the first light-emitting parameter. The flashing state is used to indicate the switching state of the multiple light-emitting unit segments between the "on" state and the "off" state. In response to the charging progress indicator that the vehicle disconnects from the charging connection, within a third target duration, the multiple light-emitting unit segments are controlled to gradually switch from the "on" state to the "off" state.
[0090] In this embodiment, during the control of the light-emitting unit segment composed of multiple light-emitting units, if the charging progress indicates that the vehicle's battery level is in a first battery level range, the first light-emitting unit segment can be controlled to be in the "on" state with the first light-emitting parameter, according to the control strategy. If the battery level rises from the first battery level range to the second battery level range, the second light-emitting unit segment can be controlled to be in the "on" state with the second light-emitting parameter within a first target duration, and after the first target duration, both the first and second light-emitting unit segments can be controlled to be in the "on" state with the first light-emitting parameter. If the battery level is low, the multiple light-emitting unit segments can be controlled to flash at a preset frequency within a second target duration, and after the second target duration, the multiple light-emitting unit segments can be controlled to be in the "on" state with the first light-emitting parameter. If the vehicle disconnects from the charging connection, the multiple light-emitting unit segments can be gradually switched from the "on" state to the "off" state within a third target duration.
[0091] Optionally, the aforementioned first and second battery level ranges can be relative concepts; that is, the second battery level range can be a range with a higher battery level than the first battery level range. The first battery level range can refer to a preset percentage range representing the low battery stage in the charging progress, such as 0%–20%, used to trigger the activation of the initial light-emitting unit segment, indicating that the vehicle is about to begin charging or is in the initial charging stage, providing early status confirmation for the user. Correspondingly, the second battery level range refers to the next stage range in the charging progress above the first battery level range, such as 21%–40%, used to trigger the activation of the adjacent subsequent light-emitting unit segment, indicating that the charging state has entered the middle stage. If the first battery level range is 40%–60%, then the second battery level range can be 60%–80%, and so on; no specific restrictions are imposed here.
[0092] Optionally, the aforementioned first light-emitting unit segment can refer to the first light-emitting unit segment arranged in spatial order among the light-emitting components, corresponding to the first power range, and is activated first when charging begins, serving as the initial visual identifier for visualizing the charging status. The aforementioned first light-emitting parameters can refer to the baseline brightness, color, and stable state set for the light-emitting unit segment in normal display mode, such as constant light, warm white, and 100% brightness, used to maintain a continuous and stable expression of charging progress. The aforementioned second light-emitting parameters can refer to an instantaneous enhanced light-emitting attribute higher than the first light-emitting parameters, for example, brightness increased to 1.5 times, used to provide dynamic feedback at the moment a new light-emitting unit segment is activated, strengthening the perception of "progress advancement." The aforementioned "on state" can refer to the stable working state where the light-emitting unit segment is activated by the driving circuit and continuously emits light, distinct from the "off state," and is the basic output form for displaying charging progress. The aforementioned second light-emitting unit segment can refer to the next light-emitting unit segment arranged in spatial order immediately following the first light-emitting unit segment, used to respond to the power level rising to the second power range, achieving continuous expansion of the light effect.
[0093] Optionally, the first target duration can refer to the time window from the illumination of the first light-emitting unit segment to the activation and brightness enhancement of the second light-emitting unit segment. For example, it can be set to 0.5–1.0 seconds to create a smooth and orderly visual transition and avoid abrupt interference. The second target duration can refer to the duration for which the light-emitting unit segment flashes at a preset frequency when charging is complete. For example, it can be set to 3–5 seconds to convey a clear signal of "charging complete" and enhance user recognition. The flashing state can refer to the dynamic mode in which the light-emitting unit segment periodically switches between the on and off states at a fixed frequency to characterize the special event of charging completion, distinguishing it from constant light or gradual display. The third target duration can refer to the delay time for the light-emitting unit segment to gradually dim from full brightness to complete shutdown after the vehicle disconnects from the charging connection. It can be set to 20–30 seconds to provide a buffer period for the user and avoid sudden loss of information.
[0094] Optionally, in response to the charging progress indicator indicating that the vehicle's battery level is in a first charge range, the domain controller detects a charging start signal and the state of charge is within a preset low charge threshold range (e.g., 0%–20%), then triggers the activation of the first light-emitting unit segment. The domain controller sends a control command to the drive circuit corresponding to this light-emitting unit segment, causing it to enter the on state with the first light-emitting parameters, that is, to emit stable light with a reference brightness and a fixed color (e.g., white), serving as the initial visual confirmation of the charging behavior, ensuring that the user perceives the start of charging immediately outside the vehicle, avoiding information delay.
[0095] Optionally, in response to the charging progress indicator indicating that the battery level has increased from a first range to a second range (e.g., 21%–40%), the domain controller immediately initiates transition control logic after detecting that the battery level has exceeded the threshold. During the first target duration, the system controls the second luminous unit segment to enter the on state with a second luminous parameter (e.g., 1.5 times the brightness) higher than the first luminous parameter, forming an instantaneous high-brightness feedback to highlight the "progress" action; the first luminous unit segment maintains its original first luminous parameter unchanged. After the first target duration ends, the brightness of the second luminous unit segment automatically drops back to the first luminous parameter, maintaining the same brightness as the first luminous unit segment, together forming a continuously lit light segment, achieving a smooth expansion from a single segment to two segments without visual jumps, enhancing the user's continuous perception of battery growth.
[0096] Optionally, in response to the charging progress indicator showing a fully charged state (i.e., 100% state of charge), the domain controller enters a completion confirmation mode. During the second target duration, the system controls all light-emitting units to flash at a preset frequency (e.g., 1Hz), periodically switching between on and off states to create a clear "charging complete" warning signal. After this mode lasts for 3 to 5 seconds, the system automatically switches all light-emitting units back to the stable on state of the first light-emitting parameter, maintaining constant illumination as a continuation of the completion notification, preventing sudden information loss and user misjudgment.
[0097] Optionally, in response to the vehicle disconnecting from the charging progress indicator, the domain controller initiates a dimming procedure upon receiving a disconnection detection signal from the charging gun and a door unlock signal. Over a third target duration (typically 20–30 seconds), the system gradually reduces the brightness of all light-emitting units in a linear decay manner until completely off, creating a gentle "exit" effect. This process provides users with ample visual buffer time, ensuring that charging status information remains visible after disconnection, enhancing the integrity and user-friendliness of the interactive experience.
[0098] In this embodiment, the method described above, through a refined control strategy that employs phased, regional, and temporal approaches, transforms abstract power data into a visual language that aligns with human cognitive logic, achieving a fully visualized representation of the charging status from initiation, progression, completion, to termination. This method not only significantly improves the readability and safety of external vehicle information but also enhances user emotional identification and confidence through dynamic feedback and gradual termination mechanisms, establishing a technological paradigm for intelligent exterior interaction that combines functionality, safety, and user experience.
[0099] As an optional embodiment, step S206 involves controlling multiple light-emitting units to display the highest priority status information among multiple status information according to the control strategy corresponding to the priority. This includes: responding to the highest priority status information triggering the vehicle's welcome function module, performing multiple stages of control on the multiple light-emitting units according to the control strategy corresponding to the welcome function module, so as to display the welcome function triggered by the welcome function module.
[0100] In this embodiment, during the process of controlling multiple light-emitting units to display the highest priority status information according to the priority-corresponding control strategy, if the highest priority status information triggers the vehicle's welcome function module, multiple stages of control can be executed on the multiple light-emitting units according to the corresponding control strategy to display the welcome function triggered by the welcome function module. The welcome function module can refer to a perception and control subsystem in the vehicle used to detect user approach behavior and trigger preset interactive responses. It consists of a Bluetooth key recognition unit, an ultrasonic or millimeter-wave radar sensor, and a logic judgment module of the vehicle domain controller. It automatically identifies the user and generates a "welcome trigger signal" when the user enters a preset sensing range (e.g., 2-3 meters) with an authorized key, serving as the entry condition for intelligent interaction. The aforementioned welcome function can refer to a dynamic light effect sequence with a sense of ceremony and emotional expression executed by the light-emitting unit segment after being triggered by the welcome function module. This sequence conveys a welcoming, respectful, and technologically advanced interactive experience to the user. Its manifestations include breathing illumination of the vehicle logo area, flowing animation of trim strips, and color gradients, serving as a visual carrier for non-verbal emotional connection between the vehicle and the user.
[0101] Optionally, the aforementioned multiple stages can refer to several sequential light effect segments that are broken down in the time dimension of the welcoming function and executed in turn. Each stage corresponds to specific light-emitting unit segment control commands and time parameters. For example, the first stage is the car logo slowly illuminating in a low-frequency breathing manner, the second stage is the side trim strips illuminating segment by segment from the center to both ends in a flowing manner, and the third stage is the overall soft and constant light as a lingering prompt. There is a clear temporal logic and visual connection between each stage, which together constitute a complete and coherent welcoming ceremony.
[0102] Optionally, in response to the highest priority status information triggering the vehicle's welcome function module, the domain controller determines that the welcome function is activated upon receiving a valid authentication signal from the Bluetooth key or RFID sensor. The domain controller then invokes the control strategy corresponding to the welcome function module, which is a three-stage light effect sequence stored in non-volatile memory.
[0103] For example, in the first stage, the domain controller controls the luminous unit segment located in the front logo area of the vehicle to gradually illuminate in a breathing pattern with a period of 2 seconds. The brightness rises steadily from 0% to 80% and then falls back to 30%, completing a full cycle of light and dark, serving as the start signal for the welcome ceremony. In the second stage, after the first stage completes three breathing cycles, the domain controller activates the luminous unit segment located on the side trim of the vehicle body, executing a flowing animation by illuminating segment by segment from the center outwards with a delay. Each segment is illuminated at an interval of 150 milliseconds, forming a dynamic light flow extending from the logo area towards the fenders, symbolizing the extension of the welcome path. In the third stage, after the flowing animation ends, all luminous unit segments participating in the welcome ceremony maintain a low-brightness constant-on state at the first illumination parameter (e.g., 30% of the maximum brightness) until the user completes the unlocking operation or enters the vehicle, serving as a lingering reminder before the welcome ceremony ends. Each stage strictly follows the chronological order, with no overlap or interruption, and shields against interference from other low-priority state information during execution, ensuring the integrity and uniqueness of the welcome function.
[0104] In this embodiment, the method, through precise choreography of multi-stage lighting effects, elevates the welcoming function from a simple "lighting up" action to a ritualistic interactive process imbued with rhythm, spatial awareness, and emotional warmth. This not only strengthens users' perception and identification with the brand's technological sophistication but also establishes a non-verbal emotional connection between the vehicle and the user in public spaces. This mechanism, while ensuring driving safety, achieves a functional leap from "passive prompting" to "proactive care" in exterior lighting, significantly enhancing the user experience and brand value of new energy vehicles.
[0105] As an optional embodiment, in response to the highest priority state information triggering the vehicle's welcome function module, multiple stages of control are performed on multiple luminous units according to the control strategy corresponding to the welcome function module to display the welcome function triggered by the welcome function module. This includes: in response to the highest priority state information triggering the welcome function module, in the first stage, according to the control strategy, controlling multiple luminous units in the vehicle's logo area to be in a breathing state, wherein the breathing state is used to indicate that the luminous parameters of the luminous units undergo linear changes; in the second stage, according to the control strategy, controlling multiple luminous units located in the areas on both sides of the vehicle to be in a breathing state for a fourth target duration, and after the fourth target duration, to enter an open state in a preset order; in the third stage, according to the control strategy, controlling multiple luminous units to be in the open state until the driver or passenger opens the vehicle door, controlling multiple luminous units to switch from the open state to the closed state.
[0106] In this embodiment, during the process of performing multiple stages of control on multiple light-emitting units according to the control strategy corresponding to the welcome function module, in the first stage, multiple light-emitting units in the vehicle logo area can be controlled to be in a breathing state according to the control strategy. In the second stage, multiple light-emitting units located in the areas on both sides of the vehicle can be controlled to be in a breathing state for a fourth target duration, and after the fourth target duration, they can enter the open state in a preset order. In the third stage, multiple light-emitting units can be controlled to be in the open state according to the control strategy until the driver or passenger opens the vehicle door, at which point the multiple light-emitting units switch from the open state to the closed state.
[0107] The first stage can refer to the initial light effect execution after the welcome function is activated, specifically for the car logo area. It conveys the initial welcome intention through stable, slow brightness changes, serving as the visual starting point for the entire welcome ceremony. The aforementioned "breathing state" refers to the dynamic pattern of the light-emitting unit's luminous parameters (brightness) periodically rising and falling according to a linear function between preset minimum and maximum values, simulating the breathing rhythm of a living organism to create a gentle, friendly, and technologically-inspired interactive atmosphere. The second stage can refer to the secondary light effect linking the first stage of the welcome function, focusing on the trim areas on both sides of the vehicle. It activates after the car logo's "breathing" effect is complete, expanding the welcome range and enhancing the sense of spatial extension and ceremonial sequence. The fourth target duration can refer to the time window during which the light-emitting unit maintains the "breathing state" in the second stage, which can be set to 1.0–1.5 seconds to ensure a sufficiently smooth brightness transition, allowing users to perceive a dynamic transition rather than an abrupt lighting up. The aforementioned preset sequence refers to the fixed timing logic of the light-emitting units on both sides lighting up sequentially from the center of the vehicle outwards, ensuring a clear, symmetrical, and unified flow effect, forming a directional visual path.
[0108] Optionally, the third stage mentioned above can refer to the final stable state of the welcoming ceremony, where all participating light-emitting units remain on with a constant low brightness as a continuous prompt for the user as they approach the vehicle, until the door is opened and a closing command is triggered, thus completing the interactive loop.
[0109] Optionally, in the first stage, upon receiving a user approach confirmation signal from the welcome function module, the domain controller immediately activates the lighting response in the logo area. All luminous units in this area are uniformly controlled, operating in a breathing mode, meaning their luminous parameters smoothly rise and fall along a linear function between preset low and high brightness thresholds, with a cycle set to 2 seconds to complete one full light-dark cycle. This stage only activates the logo area, without affecting other parts of the vehicle body, aiming to convey a dignified welcome signal with focused and tranquil dynamic light and shadow, avoiding visual clutter caused by multiple points of simultaneous illumination, and strengthening the emotional focus of the brand identity.
[0110] Optionally, in the second stage, after the first stage completes three breathing cycles, the domain controller activates the light-emitting units in the side trim areas. During the fourth target duration, all light-emitting units in both sides synchronously enter a breathing state, maintaining a rhythm consistent with the car logo to create a visually responsive visual rhythm and enhance the unity of the ceremony. After the fourth target duration ends, the system activates the light-emitting units segment by segment in a preset order, starting from the center position near the car logo and extending sequentially towards the left and right fenders, with each segment illuminating at a 150-millisecond interval, forming a symmetrical and smooth flowing light effect from the inside out. This process does not use instantaneous illumination but rather a smooth transition to the on state after a breathing transition, ensuring a natural dynamic connection and avoiding abrupt jumps.
[0111] Optionally, in the third stage, once the flowing animation in both sides is complete, all the luminous units involved in the welcoming gesture turn on and maintain a stable low brightness level (e.g., 30% of maximum brightness) at the first luminous parameter, serving as a continuous prompt when the user approaches. This state continues until the driver or passenger unlocks the door. At this point, the domain controller detects the door opening signal and immediately triggers a closing command. All luminous units gradually turn off from the on state in a linear decay manner for at least 2 seconds, ensuring a smooth and natural exit of the light effect and avoiding abrupt information interruptions that could disrupt the experience.
[0112] In this embodiment, the three-stage control process of the above method, through the introduction of breathing rhythm, the extension of the flow sequence, and the closed-loop design of a smooth conclusion, elevates the welcoming function from a simple "lighting up" behavior to a complete interactive ritual with emotional tension and spatial logic. This mechanism not only significantly enhances users' perception and recognition of the vehicle's technological attributes, but also builds a non-verbal emotional bond between people and intelligent devices in public scenarios, setting a technological benchmark for intelligent exterior interaction that combines aesthetics, safety, and experiential depth.
[0113] As an optional embodiment, step S206 involves controlling multiple light-emitting units to display the highest priority status information among multiple status information according to the control strategy corresponding to the priority. This includes: responding to the highest priority status information triggering the vehicle's turn signal function module, controlling multiple light-emitting units to be in a flashing state according to the control strategy corresponding to the turn signal function module, in order from the inside of the vehicle to the outside of the vehicle, to display the turn signal function triggered by the turn signal function module. The flashing state is used to indicate the state of multiple light-emitting units switching between an on state and an off state.
[0114] In this embodiment, during the process of controlling multiple light-emitting units to display the highest priority status information, if the highest priority status information triggers the vehicle's turn signal indication module, multiple light-emitting units can be controlled to flash in sequence from the inside to the outside of the vehicle according to the corresponding control strategy to display the turn signal indication function. The turn signal indication module refers to a sensing and logic processing unit in the vehicle used to detect the driver's turning intention and generate control signals. It consists of a turn signal switch signal acquisition circuit, a body domain controller, and a CAN bus communication interface. When the turn signal is activated, it identifies the turning direction in real time and triggers the exterior lighting response, serving as the signal source for active safety interaction. The aforementioned turn signal indication function refers to the dynamic light effect presented by the light-emitting units flashing synchronously at a frequency in sequence from the inside to the outside of the vehicle after being triggered by the turn signal indication module. This clearly conveys the vehicle's intention to change lanes or turn to surrounding road users. Essentially, it extends the flashing behavior of traditional lights to a spatially directional dynamic exterior indication, improving the intuitiveness and safety of driving interaction.
[0115] Optionally, in response to the highest priority status information triggering the vehicle's turn signal indicator module, the domain controller receives the CAN signal from the turn signal switch in real time to confirm the left or right turn command. The domain controller then activates the control strategy corresponding to the turn signal indicator module, controlling multiple light-emitting units to flash sequentially from the inside of the vehicle to the outside. This sequence strictly corresponds to the vehicle's turning direction: for a left turn, the light-emitting unit segment closest to the center of the vehicle body is triggered sequentially towards the left fender; for a right turn, it is triggered sequentially from the center towards the right fender. The flashing frequency of each light-emitting unit segment is synchronized with the vehicle's original turn signals, typically 1.5Hz, and all units switch synchronously between on and off states without delay or misalignment. This control strategy does not employ segment-by-segment delayed flow, but rather is based on overall synchronous flashing, activating light-emitting unit segments only according to spatial position sequence. This ensures the light effect presents as a consistent rhythmic "light strip flashing" extending from the inside out, allowing rear and side traffic participants to clearly identify the turning direction and range.
[0116] In this embodiment, the method deeply integrates the turn signal indication function with the spatial layout of the exterior lighting unit, expanding the expression of turning intention from a single light source point to a dynamic light band with spatial extension, significantly enhancing the visibility range and directional recognition of the indication. Compared to traditional turn signals, this method provides stronger visual penetration in low-light, rainy, foggy, or complex traffic environments, while avoiding visual misleading and ensuring driving safety. This mechanism achieves a dual improvement in function reuse and safe interaction without adding extra hardware, providing a reliable technical path for the application of intelligent exteriors in the field of active safety.
[0117] As an optional embodiment, step S206 involves controlling multiple light-emitting units to display the highest priority status information among multiple status information according to the control strategy corresponding to the priority. This includes: responding to the highest priority status information being the driving status module that triggers the vehicle, and the driving status module being in an active state, controlling multiple light-emitting units in a preset area to be in a preset color-activated state according to the control strategy of the driving status module, so as to display the driving status triggered by the driving status module.
[0118] In this embodiment, during the process of controlling multiple light-emitting units to display the highest priority status information, if the highest priority status information is the driving status module that triggers the vehicle and the driving status module is in an active state, multiple light-emitting units in the preset area can be controlled to be in a preset color-activated state according to the corresponding control strategy to display the driving status triggered by the driving status module.
[0119] The driving status module refers to the control system in the vehicle used to monitor and determine the operating status of intelligent driving functions. It consists of an intelligent driving domain controller, a sensor fusion unit, and a status signal output interface. It identifies whether the vehicle is in advanced driving modes such as autonomous driving, navigation assistance, or driver assistance, and is a crucial source of information conveying the vehicle's autonomous behavior to the outside world. The aforementioned activation state refers to the deterministic condition that the driving status module has detected the successful activation and continuous operation of the intelligent driving function. At this point, the system has taken over some or all of the driving control and needs to clearly indicate its operating status to enhance safety awareness of the surrounding environment. The aforementioned preset area refers to a specific luminous area predefined on the vehicle's exterior to display driving status information. For example, it could be a ring of light around the central logo or other highly recognizable structures. Its position is fixed, its boundaries are clear, and it is specifically designed to distinguish it from other interactive functions (such as welcome or charging), ensuring the exclusivity and recognizability of the status indication. The aforementioned preset colors may refer to luminous colors that are exclusively configured for the driving status module and have industry consensus or brand identity significance, such as technical blue or low-saturation cyan. These colors are used to convey the key information that "this vehicle is in automated operation" to pedestrians and other vehicles without interfering with other lighting functions, thus avoiding misjudgment caused by color confusion.
[0120] Optionally, in response to the highest priority status information triggering the vehicle's driving status module, and the driving status module being active, the domain controller receives a "Smart Driving Activation" status signal sent by the intelligent driving domain controller via the CAN bus, confirming that the vehicle has entered autonomous driving, navigation assistance, or equivalent automated driving mode. The domain controller then invokes the control strategy corresponding to the driving status module, locking a preset area—the ring-shaped light strip around the central logo—as the sole output carrier, and sends a constant brightness control command to all luminous units in that area, keeping them continuously illuminated in a preset color. This preset color is a technological blue, its color coordinates and brightness parameters calibrated by the vehicle's color system to ensure high contrast and low interference under sunlight, nighttime, and various weather conditions, and is strictly distinguishable from the luminous colors of other functions such as welcome lights and charging. The luminous units do not flicker, flow, or adjust brightness, maintaining stable and silent illumination to avoid visual fatigue or misjudgment, forming a "silent declaration" that clearly conveys the core information that "this vehicle is performing autonomous decision-making."
[0121] In this embodiment, the method presents the driving status in a constant color, fixed area, and without dynamic interference, achieving standardized and perceptible visual identification of intelligent driving functions in the external environment. This mechanism overcomes the limitations of traditional warning lights, which are often vague and easily overlooked, enabling pedestrians, cyclists, and other vehicles to identify vehicle behavior attributes immediately, effectively reducing the uncertainty risks in human-vehicle interaction. This solution requires no additional hardware; it achieves accurate expression of active safety information solely through software strategies in collaboration with existing lighting systems, establishing a clear, reliable, and scalable technical paradigm for public safety interaction in intelligent connected vehicles.
[0122] As an optional embodiment, step S206 involves controlling multiple light-emitting units to display the highest priority status information among multiple status information according to the priority-corresponding control strategy. This includes: responding to the vehicle search prompt function module with the highest priority status information being a vehicle, and the driver / passenger triggering a vehicle search command using the vehicle search prompt function module, controlling multiple light-emitting units to be in a flashing state according to the control strategy of the vehicle search prompt function module to display the vehicle search prompt function triggered by the vehicle search prompt function module. The flashing state is used to indicate the state in which multiple light-emitting units switch between an on state and an off state.
[0123] In this embodiment, during the process of controlling multiple light-emitting units to display the highest priority status information, if the highest priority status information is to trigger the vehicle search prompt function module, and the driver triggers the vehicle search command using the aforementioned vehicle search prompt function module, the multiple light-emitting units can be controlled to flash in accordance with the corresponding control strategy to display the vehicle search prompt function.
[0124] The aforementioned vehicle location prompt module refers to the communication and control unit in the vehicle used to receive remote vehicle location commands and trigger exterior lighting responses. It consists of a Telematics Box (T-BOX), a mobile terminal communication interface, and a logic execution module of the vehicle's domain controller. Upon receiving a vehicle location request from a user via a mobile app or other channels, it generates corresponding lighting control signals, serving as the technological carrier for remote vehicle positioning interaction. The aforementioned vehicle location command refers to a control command actively sent by the driver / passenger to the vehicle's remote service system via a bound mobile terminal application. This command requests the vehicle to emit visible light in large parking lots or complex environments. It contains unique authentication information and a vehicle location trigger identifier, serving as the only valid input signal to activate the vehicle location prompt function. The aforementioned vehicle location prompt function refers to the visual positioning signal presented by the vehicle location prompt module driving all exterior lighting units to flash at high frequency and high brightness after responding to the vehicle location command. Essentially, it forms a significant identification feature in the environment through a unified and eye-catching dynamic light effect, helping drivers / passengers quickly locate the vehicle. This is a key functional expression for improving the efficiency of human-vehicle interaction in parking scenarios.
[0125] Optionally, in response to the vehicle location alert module with the highest priority status information being the vehicle, and when a passenger triggers a vehicle location command via a mobile terminal application, the remote information processing control unit (T-BOX) receives and verifies the legitimacy and validity of the command. Upon confirmation, the vehicle location trigger signal is transmitted to the body domain controller via the CAN bus. The body domain controller then activates the control strategy of the vehicle location alert module, sending a high-frequency flashing control command to all luminous units. This causes all luminous units to synchronously switch between on and off states at a fixed frequency of 3Hz, maintaining brightness at over 80% of the maximum output value, ensuring high visibility in direct sunlight or low-light conditions at night. This flashing state is not region-specific or sequentially delayed; instead, it is executed globally and synchronously, forming a unified light pulse across the entire vehicle, eliminating potential identification confusion caused by localized flashing, allowing users to quickly locate the target vehicle visually in a parking lot. The flashing duration is 20 seconds. If interference signals such as vehicle unlocking or charging gun insertion are detected during this period, the vehicle location alert function is immediately terminated to ensure system safety and controllable energy consumption.
[0126] In this embodiment, the method significantly improves vehicle identifiability in densely parked environments by presenting the vehicle-finding prompt function with a globally synchronized, high-intensity, fixed-frequency flashing state. This solves the problems of noise pollution, ambiguous positioning, and easy neglect associated with traditional horn or flashing headlight methods. This method achieves accurate, quiet, and efficient vehicle positioning solely through an external lighting system without relying on sound prompts, balancing user convenience and environmental friendliness. It provides a stable, reliable, and scalable technical implementation path for remote interaction of intelligent vehicles in complex scenarios.
[0127] The technical solutions of the embodiments of this application will be illustrated below with reference to preferred embodiments.
[0128] Currently, the display of charging progress for new energy vehicles is one of the core user experience indicators. Charging progress information is currently displayed primarily through the following two methods.
[0129] The first method involves displaying the information on a large in-vehicle screen or via a mobile app. Users need to enter the vehicle or check the charging status through the mobile app, which presents the problem of a long information acquisition path and the inability to intuitively perceive the charging status from outside the vehicle.
[0130] The second approach involves intelligent exterior lighting solutions, with illuminated logos and grilles gradually being adopted. However, these solutions generally suffer from the following bottlenecks: poor appearance consistency, noticeable color difference between the illuminated area and the body paint, visible even when not illuminated, creating a strong "patchwork" visual effect that disrupts the overall aesthetic integrity of the vehicle. The structure is complex and assembly is cumbersome, requiring more than 10 components including a transparent substrate, shielding layer, cutout area, light source, shell, cover plate, and base, resulting in numerous processes, low efficiency, and significant challenges in quality control. The cost is high, and reliability is low; the display screen solution is expensive and faces risks related to waterproofing, dustproofing, heat dissipation, and long-term stability in harsh external environments. Functionality is limited, only providing static decoration or fixed pattern display, lacking intelligent interactive capabilities.
[0131] Existing translucent paint films are only used for static decoration. When applied to dynamic interactive exterior design of vehicles, they face three major technical challenges: difficulty in optical matching, difficulty in structural integration, and difficulty in process adaptation. In summary, existing technologies cannot simultaneously meet the five requirements of intuitive display of charging status outside the vehicle, integration with vehicle body design, simplified structure, low cost, and high reliability.
[0132] This application proposes an integrated intelligent luminous exterior trim component and its control method, mainly addressing the following issues: the integration of light-transmitting materials with the vehicle exterior structure, specifically how to deeply integrate existing light-transmitting films with the vehicle exterior substrate layer, light source module, and control system to achieve dynamic interactive functions while ensuring the vehicle's weather resistance and impact resistance; the visualization of charging progress on the exterior trim, addressing the user experience pain point of not being able to intuitively perceive the charging progress from outside the vehicle; the issue of appearance consistency, resolving the visual effect problem of inconsistent colors between the luminous exterior trim component and the vehicle body, resulting in a strong "patchwork" appearance; the issue of structural complexity, addressing the problems of numerous components, cumbersome assembly processes, and high costs associated with existing solutions; and the issue of functional limitation, addressing the problem of existing exterior lighting having limited functionality and lacking intelligent interactive capabilities.
[0133] The embodiments of this application will be further described below.
[0134] Figure 3 This is a schematic diagram of the layer structure of an integrated smart exterior component according to an embodiment of this application, as shown below. Figure 3 As shown, the layer structure, from the outside in, may include: a decorative functional film layer 100, a light-transmitting substrate layer 200, an intermediate layer 300, and a light source module 400. The decorative functional film layer 100 is disposed on the outer surface of the light-transmitting substrate layer 200 and is composed of a prefabricated film with light-transmitting function provided by a supplier. This film is pre-customized with the required pattern and is integrally formed with the substrate layer through in-mold labeling (IML) technology. A key characteristic is that its optical properties are consistent with standard body paint in the non-powered state; in the powered state, it allows selective transmission of backlight light, displaying a clear pattern. The light-transmitting substrate layer 200, as the main structure of the exterior trim, is made of light-transmitting materials, such as polycarbonate (PC) and polymethyl methacrylate (PMMA). Its shape can be configured as a car logo, trim strip, grille panel, or complete body panel according to design requirements. The aforementioned intermediate layer 300 is disposed between the light-transmitting substrate layer 200 and the light source module 400, and serves as a light guide plate or diffuser to improve the uniformity of light efficiency. The aforementioned light source module 400 is disposed inside the light-transmitting substrate layer 200, and includes multiple independently controllable LED beads or OLED light-emitting units, which can be arranged into a specific array or pattern. It includes a driving circuit and is electrically connected to the vehicle controller.
[0135] In this embodiment, the decorative functional film layer 100 is integrally formed with the light-transmitting substrate layer 200 through an IML in-mold injection molding process, serving as a surface functional layer of the exterior part rather than an additional decorative layer.
[0136] Optionally, such as Figure 3As shown, to achieve a "hidden" visual effect, the decorative functional film layer 100 in this embodiment is integrated with the translucent substrate layer 200 using in-mold injection molding (IML) technology. The decorative functional film layer 100 is provided by the material supplier in the form of a pre-fabricated film. This film has a multi-layer structure: using PC, PP, and PMMA as carriers (thickness 0.125mm), from bottom to top, it consists of a light-shielding layer, a high-transmittance film layer (such as PMMA), a translucent ink layer, and a transparent protective layer. The film has been pre-formed with the required translucent pattern (such as a strip of light, the outline of a car logo, etc.) precisely through screen printing or gravure printing processes. The non-translucent areas are completely covered by light-shielding ink with a light density value OD≥3.0. The translucent ink contains pigments of the same color as the car body paint, and the color difference ΔE in the non-illuminated state is < a preset color difference threshold. The aforementioned preset color difference threshold can be set according to the vehicle's design requirements. For example, to ensure that the color of the decorative functional film layer is close to that of the body paint, the preset color difference threshold can be set to 1.5 or even 0.5. The light transmittance of the light-transmitting pattern layer is set to a preset light transmittance. For example, it can be set to 45%±5% according to the vehicle's design requirements. There is no specific limitation here, and it can be flexibly adjusted according to the actual design requirements of the vehicle. The light-transmitting substrate layer 200 is made of polycarbonate (PC) material with high light transmittance and high weather resistance. It is integrally formed by injection molding. The thickness of the light-transmitting substrate layer can be set according to the vehicle's design requirements. For example, the thickness can be set to 3.0mm. A microprism structure is set on its inner surface or inside, with a prism angle of 45°~60°, to convert point light into parallel light and reduce the scattering loss of light in the decorative functional film layer 100.
[0137] It should be noted that the smaller the color difference value mentioned above, the lower the light transmittance of the light-emitting layer. The lower the light transmittance, the closer it is to the color of the vehicle body paint. The preparation parameters used in the above-mentioned process of preparing the decorative functional film layer and the light-transmitting substrate layer in this application embodiment, such as thickness, color difference, light transmittance, etc., are only illustrative examples and are not specific limitations. They can be adjusted according to the design requirements of the vehicle to present different effects.
[0138] Optionally, such as Figure 3As shown, the light source module 400 is disposed inside the light-transmitting substrate layer 200 and consists of a flexible printed circuit board (FPC) and multiple high-brightness LED beads soldered thereon. The LED beads are arranged in an array corresponding to the light-transmitting pattern on the light-transmitting functional paint layer to ensure that there are no dark areas in the light coverage. An LED driver chip is integrated on the FPC and is electrically connected to the vehicle controller via a LIN bus. An optical-grade light guide plate is added between the light-transmitting substrate layer 200 and the light source module 400 in the intermediary layer 300. The thickness of the optical-grade light guide plate can be 1.0 mm, which is not specifically limited here. Its light-emitting surface has a microstructure to convert the point light source into a uniform surface light source. In this embodiment, the luminous intensity of the light source module 400 can be set to 3000 cd / m², the thickness of the light-transmitting substrate layer 200 is 3.0 mm, the light transmittance of the decorative functional film layer 100 is 45% ± 5%, the pattern brightness in the lit state is ≥ 150 cd / m², which meets the daytime visibility requirements, and the color difference ΔE between the light source module 400 and the vehicle body in the non-lit state is < a preset color difference threshold.
[0139] It should be noted that the parameters such as the luminous intensity of the light source module, the thickness of the light-transmitting substrate layer, the light transmittance of the functional film layer, and the pattern brightness, etc., set in the embodiments of this application are all illustrative examples. Any process or method that can utilize the intelligent luminous exterior component in the embodiments of this application to realize vehicle information display, as well as the design parameters of the aforementioned intelligent luminous exterior component, are all within the protection scope of the embodiments of this application and are not specifically limited.
[0140] In this embodiment, the process scheme (IML process adaptation optimization) is as follows: diaphragm preforming and high-pressure gas forming ensure complete fit between the diaphragm and the mold cavity, preventing pattern deformation. Staged injection molding (low speed → medium speed → holding pressure) reduces diaphragm impact and wrinkling. Precise positioning using positioning pins, vacuum adsorption, and charge-coupled device (CCD) vision alignment achieves sub-millimeter alignment accuracy. Edge sealing involves injection molding to wrap the diaphragm edges, providing waterproofing and dustproofing, and improving reliability.
[0141] In this embodiment, the control scheme (multi-scenario intelligent lighting control) receives signals from the vehicle BMS, body domain, intelligent driving domain, key / phone, and APP. The domain controller analyzes these signals and drives the light source module to achieve corresponding dynamic effects: charging progress is indicated by a linearly mapped illumination ratio, a flashing indicator to indicate progress, and a full charge celebration mode. Intelligent welcome features include a breathing logo and flowing trim lighting when the driver approaches. Turn signal indication is synchronized with the turn signal frequency, creating a directional flowing effect. Intelligent driving indication displays a specific color ring to inform surrounding vehicles that they are in intelligent driving mode. Vehicle location indication flashes at high frequency for quick vehicle location. A priority mechanism is implemented to ensure driving safety by pre-setting the priority of different lighting functions. When multiple status signals are triggered simultaneously, the domain controller executes lighting control in the following priority order: turn signal indication > intelligent driving indication > intelligent welcome > charging progress display > vehicle location indication. For example, if the driver activates the turn signal while the vehicle is displaying charging progress, the domain controller immediately interrupts the charging display and switches to the flowing turn signal indication; the charging progress display resumes after the turn signal is turned off.
[0142] In this application embodiment, the beneficial effects of the above method include: optimal visual effect; the color difference ΔE between the non-illuminated state and the vehicle body paint is less than the preset color difference threshold; the smaller the color difference, the better the hidden effect of the intelligent luminous exterior parts is presented; the illuminated state has a clear pattern with a resolution ≤0.2mm. Compared with the "visible hole" solution, this application embodiment eliminates the "patchwork" feel. The structure is highly streamlined, with only three core layers. Compared to requiring more than 10 independent components, the number of parts is reduced by more than 60%, and the assembly process is reduced by more than 50%. Cost is significantly reduced: compared with the display screen solution, there is no need for a display screen module and its supporting drive circuit and heat dissipation structure, reducing hardware costs by more than 50%. Multifunctional reuse: one set of hardware realizes five interactive functions: charging display, welcome, turn signal, intelligent driving prompt, and vehicle location, achieving "one set of hardware, multi-scenario reuse".
[0143] In this embodiment, the compatibility between the IML process and the light-transmitting functional film is optimized. To achieve the integrated molding of the pre-fabricated film and the light-transmitting substrate layer 200 into an IML, and to ensure the optical performance and structural reliability of the final product, the following targeted designs were made to the IML process in this embodiment:
[0144] Method 1, One-Step Molding (Diaphragm Pre-molding): Diaphragm positioning and pre-forming: Before placing the diaphragm into the injection mold, a high-pressure gas forming process is used to pre-form the diaphragm, ensuring its shape perfectly matches the curved surface of the mold cavity. The pre-forming temperature is set above the softening point of the diaphragm material and below its thermal decomposition temperature, with pressure controlled within a range that ensures uniform adhesion. This design prevents pattern deformation or blurred boundaries of translucent areas due to excessive stretching of the diaphragm during subsequent injection molding. In the injection molding process, the mold temperature is set below the heat distortion temperature of the diaphragm material and above the glass transition temperature of the substrate material, allowing the diaphragm to soften upon heating and bond well with the substrate, while preventing overheating and deformation. A staged injection process is used: the first stage involves low-speed filling, allowing the molten plastic to slowly push the diaphragm apart, reducing impact; the second stage completes the remaining filling at medium speed; and the third stage holds pressure to ensure bonding strength. The melt temperature is selected within the optimal flow temperature range of the substrate material, where the substrate has the best fluidity and the highest weld strength with the diaphragm. For precise pattern alignment, the mold incorporates positioning pins and vacuum adsorption holes. After initial positioning by the pins, the diaphragm is tightly adhered to the mold surface via vacuum adsorption. This design ensures that the alignment accuracy between the translucent pattern and the light-emitting area of the light source module 400 is controlled within sub-millimeter levels, meeting high-precision display requirements. Edge sealing is achieved after injection molding, where the plastic material of the translucent substrate layer 200 forms a wrapping structure at the mold edge, completely encapsulating the diaphragm edge. This structure effectively prevents moisture and dust from seeping in from the edges, which could lead to film delamination or corrosion.
[0145] Method 2, Two-stage molding method (substrate first, film then lamination): This process is suitable for exterior parts with complex shapes, deep cavities, or inverted structures (such as complete body panels), avoiding pattern deformation caused by uneven stretching of the film in complex cavities during one-stage molding. Substrate pre-molding: A translucent substrate layer 200 is formed through injection molding. After cooling and solidifying in the mold, the substrate layer is retained in the mold or transferred to the two-stage molding station. Positioning references (such as positioning holes, positioning grooves, or optical identification marks) are pre-reserved on the substrate layer for film alignment. Film positioning and alignment: The pre-made translucent film is initially positioned against the positioning references on the substrate layer using mechanical positioning pins. A CCD vision alignment system is used to perform high-precision alignment between the translucent pattern on the film and the preset display area on the substrate layer. Sub-millimeter alignment accuracy can be achieved through alignment mark recognition and servo mechanism fine-tuning, meeting the requirements for high-resolution pattern display. Two-stage molding and bonding: After alignment, the film and substrate layer are bonded together through hot pressing or injection molding. During hot pressing, the diaphragm and substrate layer are molded together. A heating plate melts the adhesive layer on the back of the diaphragm, and pressure is applied to ensure a tight bond between the diaphragm and substrate layer. The heating temperature is controlled within the activation temperature range of the adhesive layer. Edge sealing is performed during the secondary molding process by forming a plastic wrapping layer or applying sealant to the edges of the diaphragm to ensure a seamless connection between the diaphragm edges and the substrate layer, preventing moisture penetration.
[0146] Through the above process design, the embodiments of this application can achieve a firm bond between the decorative functional film and the substrate layer, meeting the requirements of automotive exterior parts for weather resistance, impact resistance and long-term reliability.
[0147] The light source module 400, which integrates a light guide plate, is fixed to the inner side of the light-transmitting substrate layer 200 using a snap-fit structure, ensuring precise alignment between the light-emitting area and the light-transmitting pattern. The entire assembly is mounted to the vehicle body with screws, and the drive circuit of the light source module 400 establishes a Local Interconnect Network (LIN) bus communication connection with the body controller through a standard wiring harness.
[0148] Through the above structure and process, the exterior trim provided in this embodiment is seamlessly integrated with the car body paint when not powered on, and no trace of the light-emitting element can be seen, thus solving the problem of "patchwork" appearance; when powered on, light can be precisely transmitted from the preset pattern area to form a clear and uniform light effect.
[0149] Figure 4 This is a schematic diagram of a charging progress display according to an embodiment of this application, such as... Figure 4 As shown, the charging progress display can be used in vehicle status 41, control system 42, and exterior structure and display effect 43. Specifically, to display the charging progress, the battery management system in vehicle status 41 can obtain a charging progress signal from 0% to 100%. This charging progress signal can be transmitted to the vehicle controller in control system 42. The vehicle controller can then use a light source driving circuit to drive the light source module in exterior structure and display effect 43 to display the charging progress. The charging progress display effect can be as follows: if charging is 0%, all LEDs in the light source module are off; if charging is 50%, half of the LEDs are lit; if charging is 100%, all LEDs are lit.
[0150] Optionally, such as Figure 4 As shown, the vehicle's Battery Management System (BMS) monitors the battery's charging status in real time via the CAN bus. When the vehicle connects to a charging station and begins charging, the BMS periodically sends a charging progress signal (a value from 0-100%) to the vehicle's domain controller (intelligent cockpit domain controller or body domain controller). The domain controller, acting as the "control system" in this invention, is responsible for receiving and parsing this signal. The domain controller pre-stores a mapping relationship between charging progress and lighting effects. In this embodiment, the light source module 400 is a continuous light strip composed of 20 independently controllable LED segments. The domain controller linearly maps the received charging progress percentage to the number of LED segments that need to be illuminated (10 segments are illuminated when charging reaches 50%).
[0151] It should be noted that the number of LED segments in the light source module 300 mentioned above is only for illustrative purposes and is not subject to specific limitations. It can be flexibly set according to the design requirements of the vehicle (such as vehicle size, cost, design aesthetics, etc.).
[0152] When charging begins, the domain controller receives the charging start signal from the BMS and immediately sends a command to the light source driver circuit to control the first LED segment to light up with a soft breathing effect. At the same time, it lights up the corresponding number of LED segments according to the current power level, forming a "light column".
[0153] During charging, as the battery percentage gradually increases, the domain controller dynamically adjusts control commands, sequentially lighting up more LED segments in proportion. Each time a new segment is lit, it can briefly flash once at a brightness higher than the average (e.g., 1.5 times the brightness) to give the user a dynamic feedback of "progress."
[0154] Once charging is complete and the charging progress reaches 100%, the domain controller controls the entire light strip (all 20 LED segments) to display a preset celebration mode (such as all segments simultaneously breathing three times at a frequency of 1Hz, and then turning on continuously) to clearly inform the user that charging is complete.
[0155] When the user unlocks the vehicle and unplugs the charging gun, the domain controller, upon detecting the charging gun disconnection signal and the door lock unlock signal, controls the light source module 400 to gradually turn off after a preset delay (e.g., 30 seconds), restoring it to its completely hidden initial state.
[0156] Using the above methods, users can intuitively and clearly understand the vehicle's charging progress from outside the vehicle without entering the car or checking their mobile phones, greatly improving the convenience and technological feel of use.
[0157] Figure 5 This is a flowchart of a multi-scene intelligent lighting control method according to an embodiment of this application, such as... Figure 5 As shown, the method may include the following steps.
[0158] Step S501: Input vehicle status signal.
[0159] In this embodiment, each vehicle subsystem generates and outputs status signals related to exterior lighting interaction in real time, including charging progress percentage data output by the battery management system (BMS), unlock / lock status changes output by the door lock control system, left / right turn trigger signals output by the turn signal switch module, autonomous driving or navigation assist activation status output by the intelligent driving domain controller, and vehicle location commands from mobile users received and forwarded by the telematics control unit (T-BOX). All of the above signals are transmitted to the body domain controller via CAN, LIN, or Ethernet bus as input for multi-scenario lighting control.
[0160] In step S502, the controller receives and parses the signal.
[0161] In this embodiment, the controller can receive and parse the aforementioned vehicle status signals. If the signal requiring intelligent lighting control is a charging progress signal, steps S503 to S504 can be executed. If the signal requiring intelligent lighting control is an unlock / lock signal, steps S505 to S506 can be executed. If the signal requiring intelligent lighting control is a turn signal, steps S507 to S508 can be executed. If the signal requiring intelligent lighting control is a smart driving system status signal, steps S509 to S510 can be executed. If the signal requiring intelligent lighting control is a vehicle location signal, steps S511 to S512 can be executed.
[0162] Step S503: Control the light source to light up in segments according to a ratio.
[0163] In this embodiment, when the controller recognizes that the current signal is a charging progress signal, it linearly maps the received charging percentage values from 0% to 100% to the number of multiple independent controllable LED segments in the light source module. The controller outputs driving current segment by segment, so that the corresponding number of LED segments are lit with uniform brightness, forming a continuous light column, realizing a visual expression of the charging progress, ensuring that each percentage change corresponds to a perceptible increase or decrease in the number of light segments, and improving the user's intuitive perception of the charging status.
[0164] Step S504: Implement the display of charging progress outside the vehicle.
[0165] In this embodiment, the light column structure illuminated proportionally by the light source module allows users to clearly see the current battery charging progress outside the vehicle without entering the vehicle or operating a mobile app. This function is dynamically updated during the charging process, and adds a staged brightness flashing prompt when it is close to full charge, enhancing the user's perception of the expected charging completion point and significantly optimizing the convenience and technological feel of the new energy vehicle charging experience.
[0166] Step S505: Control the dynamic breathing / flowing water effect of the light source.
[0167] In this embodiment, when the controller detects a vehicle unlocking or locking signal, it triggers the intelligent welcome control logic. The controller first controls the LED in the central logo area to light up slowly in a breathing mode with periodic brightness increases and decreases. Then, it guides the trim strips on both sides to light up sequentially along the axial direction with segmented delays, forming a flowing light effect extending from the center to both ends, creating a sense of welcoming ceremony and enhancing the emotional interactive experience when the user approaches the vehicle.
[0168] Step S506: Implement the intelligent welcome function.
[0169] In this embodiment, a preset breathing and flowing water composite light effect is automatically activated when the user approaches the vehicle with a valid key or a bound mobile terminal. The light conveys the intention of "welcome" with a soft, gradual, and rhythmic light language, enhancing brand awareness and user sense of belonging. At the same time, it automatically enters a low-brightness constant-on state after the user completes the unlocking action, and then turns off after a delay after the door is opened, achieving a balance between interactive closed loop and energy saving.
[0170] Step S507: Control the light source to create a water flow effect in a specified direction.
[0171] In this embodiment, when the controller receives the turn signal activation signal, it immediately identifies the turning direction and activates only the corresponding exterior light-emitting area. The controller illuminates the LED units segment by segment from the inside of the vehicle (near the center of the vehicle body) to the outside (towards the fender) according to a preset timing sequence, forming a dynamic flowing light effect that is completely consistent with the physical turning direction of the vehicle, ensuring that road users behind and to the side can clearly perceive the vehicle's intention.
[0172] Step S508: Implement the function redirection flow prompt.
[0173] In this embodiment, the function performs directional sequential illumination at a frequency synchronized with the vehicle's original turn signals (e.g., 1.5Hz). It utilizes the large, high-brightness light-emitting area of the exterior trim to enhance the visual communication of the turning intention. Compared with traditional small turn signals, it significantly improves the recognition distance and reaction efficiency in low visibility conditions such as nighttime, rain, and fog, thereby enhancing driving safety.
[0174] Step S509: Control the light source to illuminate a constant blue light / flowing effect.
[0175] In this embodiment, when the controller detects that the intelligent driving system has been activated, it immediately drives the LED unit in the central car logo or the ring light strip area to output a technological blue light with a specific color temperature, and displays it continuously in a slow, flowing manner. The light flow speed is set to complete one revolution every 3 seconds to ensure that the signal is stable, non-interference, and recognizable.
[0176] Step S510: Implement intelligent driving status prompts.
[0177] In this embodiment, the function uses a highly recognizable blue flowing light effect to convey the clear message that "this vehicle is in autonomous or assisted driving mode" to surrounding pedestrians, cyclists and other vehicles, reducing the uncertainty of the public about the behavior of intelligent vehicles, improving road safety, reflecting the vehicle's level of intelligence and strengthening the brand's technological image.
[0178] Step S511: Control the light source to flash at high frequency.
[0179] In this embodiment, when the controller receives a legitimate vehicle search command forwarded by the T-BOX, it immediately activates the global synchronization control strategy, driving all exterior lighting units of the vehicle to flash at a frequency of 3Hz in a full-amplitude, synchronous high-brightness manner between the on and off states, maintaining the brightness at more than 80% of the maximum output value, ensuring significant visibility even in strong light or long-distance environments.
[0180] Step S512: Implement the vehicle location prompt function.
[0181] In this embodiment, the function enables users to quickly locate the target vehicle visually in large parking lots or complex environments by using a uniform, high-frequency, and high-brightness flashing response throughout the vehicle. This avoids problems such as disturbing the peace with horns and difficulty in identifying the vehicle due to scattered lights, providing a quiet, efficient, and interference-free remote vehicle-finding solution and improving user convenience and satisfaction.
[0182] In this embodiment, the intelligent interactive function of the exterior parts is further expanded, realizing dynamic lighting effects in various scenarios. The control process is as follows: Figure 5 As shown. In this embodiment of the application, the exterior trim is a through-type trim strip arranged on the tailgate of the vehicle. Its decorative functional film layer 100 has a variety of patterned areas preset, such as the central car logo area and the strip areas on both sides. The light source module 400 is also divided into multiple independent control areas accordingly.
[0183] Optionally, for the intelligent welcome function, when the car owner approaches the vehicle with the car key or a linked smartphone and enters the preset sensing range (e.g., 2-3 meters), the vehicle's door lock system detects a valid key via Bluetooth or RFID technology and sends an "unlock ready" signal to the domain controller. The domain controller, based on the preset "intelligent welcome" mapping, controls the light source module 400 to execute the following dynamic modes: First, the car logo area slowly illuminates in a breathing mode (brightness linearly increases from 0% to 80%, then linearly decreases to 20%, with a cycle of 2 seconds), in a warm white color. Second, after three breathing illuminations, the strip lights on both sides of the continuous trim illuminate sequentially from the center to both ends in a flowing pattern, completing a full "welcome" animation with a total duration of 1.5 seconds. Third, the entire light strip remains constantly lit at a soft, low brightness (e.g., 30% of maximum brightness) as a position light until the user unlocks and opens the car door, at which point the lights gradually dim.
[0184] Optionally, for the turn signal flow indicator function, when the driver activates the left turn signal, the turn signal switch signal is sent to the domain controller via the CAN bus. The domain controller monitors this signal in real time and controls the light source module 400 according to the mapping relationship of the "turn signal flow indicator". At this time, the strip light of the exterior trim is activated, and it lights up rapidly and sequentially from the inside of the vehicle to the outside (i.e., from the end near the logo towards the fender), forming a clear yellow dynamic flow effect. The frequency is synchronized with the original turn signal flashing frequency of the vehicle (e.g., 1.5Hz), providing a clear indication of the turning intention to vehicles and pedestrians behind and to the side.
[0185] Optionally, for the intelligent driving status indication function, when the vehicle enters an advanced intelligent driving mode (such as autonomous driving or navigation assistance), the intelligent driving domain controller sends an "intelligent driving activation" status signal to the domain controller. Upon receiving this signal, the domain controller controls a specific area of the light source module 400 (e.g., the ring-shaped light strip around the central logo) to emit a specific color (such as tech blue) and display a slowly flowing light effect (e.g., flowing in a circle every 3 seconds). This function clearly communicates to surrounding road users (pedestrians, other vehicles) that the vehicle is in an autonomous driving state, reminding them to pay attention to the vehicle's potential autonomous behavior.
[0186] Optionally, for the vehicle location alert function, when a user is looking for their vehicle in a large parking lot, they can send a "find vehicle" command to the vehicle's telematics control unit (T-BOX) via a mobile app. Upon receiving the command, the T-BOX converts it into a CAN signal and sends it to the domain controller. The domain controller then activates the "find vehicle alert" mode, controlling the entire exterior lighting module 400 to operate in a high-frequency flashing mode (e.g., alternating on and off flashing at a frequency of 3Hz and 80% of maximum brightness) for 20 seconds to help the user quickly locate their vehicle in the parking lot.
[0187] In this embodiment, the exterior trim and its control system provided by the above method can achieve multifunctional and dynamic lighting interaction based on various vehicle status signals and user commands. All functions share the same hardware structure, and functional expansion can be achieved simply by adjusting the software strategy, truly achieving integration and intelligence.
