[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this application to enable readers to better understand this application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can be implemented. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0021] This application provides a method for controlling a light-emitting trim piece 10 to emit light. The light-emitting trim piece 10 is located inside a vehicle and is an interior trim piece. The light-emitting trim piece 10 can be located on the inside of a vehicle door, for example, as a door trim panel. The light-emitting trim piece 10 can also be located in other locations in the vehicle, for example, as a pillar trim panel, dashboard, or sub-dashboard.

[0022] The luminous trim control method can be executed by the trim controller in the luminous trim control system. Of course, in other embodiments, the luminous trim control method can also be executed by the cockpit domain controller in the luminous trim control system, or by other domain controllers.

[0023] Reference Figure 1 A method for controlling luminous decorative elements includes: S101, acquire at least one mode switch signal corresponding to at least one scene mode, and acquire the status of the vehicle door.

[0024] The scene mode refers to a mode that controls the luminous ornament 10 to emit corresponding lighting effects based on user touch operation or voice triggering. The lighting effects presented by the luminous ornament 10 differ depending on the scene mode. Preferably, there are multiple scene modes, meaning the luminous ornament 10 has various different lighting effects. At least one mode switch signal corresponds one-to-one with at least one scene mode.

[0025] The mode switch signal indicates whether the corresponding scene mode is on or off. The mode switch signal has two states: on and off. The mode switch signal can include the name information of the scene mode and the switch status information. The name information of the scene mode can be represented by a field name, and the switch status information can be represented by a field value.

[0026] The status of a vehicle door is divided into an open state and a closed state. When obtaining the status of a vehicle door, the door can be the driver's side door, the passenger side door, or any door. When the luminous trim 10 is provided on the door, the door is specifically the door on which the luminous trim 10 is installed.

[0027] When the illuminated trim control method is executed by the trim controller, the vehicle door status and at least one mode switch signal can be obtained by the cockpit domain controller and sent to the trim controller. That is, the trim controller receives the vehicle door status and at least one mode switch signal from the cockpit domain controller.

[0028] S102, if one of the mode switch signals is in the on state, the currently enabled scene mode is determined according to the mode switch signal in the on state, the corresponding first lighting effect is determined according to the currently enabled scene mode, and the lighting ornament is controlled to emit light according to the first lighting effect.

[0029] If all mode switch signals are in the off state, it is determined that no scene mode is currently enabled.

[0030] The currently active scene mode is determined based on a mode switch signal that is in the "on" state. Specifically, the scene mode corresponding to this "on" mode switch signal is taken as the currently active scene mode. It should be noted that only one scene mode can be active at a time; multiple scene modes cannot be active simultaneously. Lighting effects refer to lighting displays that create specific visual effects. There are various types of first lighting effects, each corresponding to a scene mode; different scene modes correspond to different first lighting effects. The correspondence between scene modes and first lighting effects is pre-stored.

[0031] When the luminous ornament 10 is illuminated, it can display various patterns. There are multiple lighting effects, such as a single pattern static display, a single pattern dynamic display, multiple patterns static cycle display, and multiple patterns dynamic cycle display. When the luminous ornament 10 is illuminated, it can display a first pattern, a second pattern, or a third pattern. The first pattern can be... Figure 7 The star pattern shown can be followed by a second pattern. Figure 8 The meteor pattern shown, the third pattern can be Figure 9 The image shows a superimposed star and meteor pattern. The three patterns can be displayed statically or dynamically, such as flowing, flashing, or breathing effects. The first lighting effect has multiple types, such as flowing meteor pattern, flowing star and meteor pattern superimposed on star, static star pattern, flashing star pattern, breathing star pattern, and dynamic cyclical display of multiple patterns.

[0032] Reference Figures 4 to 6 The luminous decorative element 10 includes a light source, which may include one or two light sources, such as a first light source 14 and a second light source 15. Specifically, the light source is an LED (light-emitting diode) light source. When the luminous decorative element control method is executed by the decorative element controller, refer to... Figure 4 The decorative component controller can control the light source in the luminous decorative component 10 through the LED driver, thereby controlling the luminous decorative component 10 to emit light according to the corresponding lighting effect.

[0033] S103, if the state of the door changes, the second lighting effect is determined according to the change in the state of the door, and the lighting effect of the luminous trim is controlled according to the second lighting effect.

[0034] The change in the door's state refers to either switching from a closed state to an open state, or vice versa. The second lighting effect has at least two types, such as a door opening warning light effect and a welcome light effect, corresponding to the door's state change. The second lighting effect has a higher priority than the first lighting effect; that is, when the luminous trim 10 needs to display a second lighting effect, it should display the second lighting effect regardless of whether the first lighting effect is currently being displayed. Specifically, if the luminous trim 10 is displaying the first lighting effect, the second lighting effect can interrupt and replace the first lighting effect; if the luminous trim 10 is displaying the second lighting effect, it will not be interrupted by the first lighting effect.

[0035] In this embodiment, the luminous trim 10 can display various lighting effects when it emits light, thereby enhancing the visual richness of the driving environment and achieving a personalized cabin experience for multiple scenarios. Furthermore, the lighting effects of the luminous trim 10 are linked in real-time with changes in the vehicle door status. The luminous trim 10 displays corresponding lighting effects as the vehicle door status changes, enhancing the interaction between the driver and the vehicle, improving the technological and luxurious feel of the luminous trim 10, and ultimately improving the user experience. Additionally, the second lighting effect corresponding to a change in vehicle door status has a higher priority than the first lighting effect; that is, regardless of whether the luminous trim 10 is currently displaying the first lighting effect, the linkage between changes in vehicle door status and the lighting effects of the luminous trim 10 can be achieved.

[0036] In some embodiments, the luminous trim 10 is disposed on the vehicle door; Obtain the status of the vehicle's doors, including: obtaining the status of doors with illuminated trim pieces installed; The second lighting effect is determined based on the change in the state of the car door, including: if the state of the car door changes from closed to open, the second lighting effect is determined to be a door opening warning lighting effect; if the state of the car door changes from open to closed, the second lighting effect is determined to be a welcome lighting effect.

[0037] The luminous trim piece 10 can be installed on the driver's side and passenger side doors, or on each door of the vehicle. When there are multiple luminous trim pieces 10, each luminous trim piece 10 can be controlled by a separate trim piece controller. The cockpit domain controller is used to obtain the status of the door on which the luminous trim piece is installed and send the status of the door to the trim piece controller corresponding to that luminous trim piece.

[0038] For example, the cockpit domain controller obtains the status of the driver's door equipped with illuminated trim and sends this status to the trim controller corresponding to the illuminated trim on the driver's door. The closed state of the door can be represented by "Closed," meaning closed, and the open state can be represented by "Opened," meaning open. If the cockpit domain controller obtains that the driver's door equipped with illuminated trim is closed, it can send "DrvrDoorSt=0x1:Closed" to the trim controller to indicate that the driver's door is closed, where "DrvrDoorSt" represents the driver's door status. If the cockpit domain controller obtains that the driver's door equipped with illuminated trim is open, it can send "DrvrDoorSt=0x2:Opened" to the trim controller to indicate that the driver's door is open.

[0039] The door opening warning light effect can be a single pattern dynamically displayed or multiple patterns dynamically cycled. For example, the door opening warning light effect can be a shooting star pattern flashing, or a star pattern superimposed on a shooting star pattern flashing. In this embodiment, when the door status changes from closed to open, the luminous decorative element 10 presents a door opening warning light effect, providing a visual warning to vehicles, cyclists, or pedestrians behind, and reminding the user to close the door in time.

[0040] The welcome lighting effect differs from the door opening warning lighting effect. The welcome lighting effect can be a single pattern dynamically displayed or multiple patterns dynamically cycled. For example, the welcome lighting effect can be a breathing meteor pattern or a breathing star pattern superimposed on a meteor pattern. In this embodiment, when the door status changes from open to closed, the luminous trim 10 displays the welcome lighting effect, which can realize the welcome function and enhance the user experience.

[0041] In some embodiments, refer to Figure 2 Another method for controlling luminous decorative elements includes: S201, Obtain at least one mode switch signal corresponding to at least one scene mode, and obtain the status of the vehicle door; S202, if one of the mode switch signals is in the on state, the currently enabled scene mode is determined according to the mode switch signal in the on state, the corresponding first lighting effect is determined according to the currently enabled scene mode, and the lighting ornament is controlled to emit light according to the first lighting effect. S203, if the state of the car door changes and a scene mode is currently enabled, the currently enabled scene mode is stored, the second lighting effect is determined according to the change in the state of the car door, and the lighting of the luminous trim is controlled according to the second lighting effect. S204, if the duration of the luminous ornament emitting light based on the second lighting effect reaches the set time, then the corresponding first lighting effect is determined according to the stored scene mode, and the luminous ornament is controlled to emit light according to the first lighting effect; S205 If the vehicle is powered off before the duration of the luminous trim illuminated by the second lighting effect reaches the set time, when the vehicle is powered on again, the corresponding first lighting effect is determined according to the stored scene mode, and the luminous trim is controlled to illuminate according to the first lighting effect.

[0042] If one of the mode switch signals is in the ON state, it is determined that a scene mode is currently activated. If all mode switch signals are in the OFF state, it is determined that no scene mode is currently activated. If the state of the door changes and no scene mode is currently activated, the second lighting effect is determined directly based on the change in the door state, and the luminous trim is controlled to emit light according to the second lighting effect. S204 and S205 will not be executed subsequently.

[0043] The set time specifically refers to the duration the second light effect should appear without interruption. The set time can be set according to actual needs, such as 10 seconds, 15 seconds, 30 seconds, 45 seconds, 60 seconds, etc.

[0044] When the duration of the second lighting effect emitted by the luminous trim 10 reaches the set time, the second lighting effect ends, and the first lighting effect resumes. If the vehicle is powered off before the set time has elapsed, the second lighting effect is interrupted. Upon powering back on, the first lighting effect resumes. In this embodiment, the second lighting effect automatically reverts to the first lighting effect after it has been emitted, without requiring manual intervention.

[0045] In some embodiments, if the state of the vehicle door changes, a second lighting effect is determined based on the change in the state of the vehicle door, and the luminous trim is controlled to emit light based on the second lighting effect, including: if the state of the vehicle door changes and no scene mode is currently enabled, a second lighting effect is determined based on the change in the state of the vehicle door, and the luminous trim is controlled to emit light based on the second lighting effect.

[0046] In some embodiments, the scene mode includes at least a driving mode; The first lighting effect is determined based on the currently enabled scene mode, including: if the currently enabled scene mode is driving mode, the vehicle speed is obtained and the first lighting effect is determined based on the vehicle speed.

[0047] The vehicle speed can be obtained by the cockpit domain controller and sent to the trim controller. The driving mode switch signal can also be obtained by the cockpit domain controller and sent to the trim controller. This signal can include the scene mode name and its on / off status. The scene mode name can be represented by a field name, and the on / off status by a field value. For a driving mode that is active, the switch signal can be `drivingmodeSet=0x2:ON`, where `drivingmodeSet` is the scene mode name, specifically indicating the driving mode setting, and `0x2:ON` indicates the on / off status (ON means active). For a driving mode that is deactivated, the switch signal can be `drivingmodeSet=0x1:OFF`, where `0x1:OFF` indicates the off status (OFF means deactivated).

[0048] In this embodiment, in driving mode, the lighting effect of the luminous trim 10 is linked to the vehicle speed in real time. The lighting effect of the luminous trim 10 changes with the vehicle speed, which can further enhance the interaction experience between people and vehicles, improve the technological and luxurious feel of the luminous trim 10, enhance the immersive driving experience, and improve the user experience.

[0049] In some embodiments, determining a first lighting effect based on vehicle speed includes: determining the set speed range in which the vehicle speed is located from at least two set speed ranges; and determining the corresponding first lighting effect based on the set speed range in which the vehicle speed is located.

[0050] In driving mode, the first lighting effect can be a flowing display of a shooting star pattern, or a flowing display of stars superimposed on a shooting star pattern. At least one of the pattern, color, or flowing speed of the first lighting effect will be different for different vehicle speed ranges. Preferably, at least the flowing speed will be different for the first lighting effect corresponding to different vehicle speed ranges.

[0051] At least two preset speed ranges can be set according to actual needs, such as [0, 50) km / h, [50, 80) km / h, [80, 100) km / h, [100, 120) km / h, etc. The vehicle speed can be sequentially matched with these two preset speed ranges to determine the specific speed range within which the vehicle falls. The correspondence between the preset speed ranges and the first lighting effect is pre-stored.

[0052] In this embodiment, the first lighting effect is determined according to the set speed range of the vehicle speed, so as to avoid frequent switching of lighting effects.

[0053] In some embodiments, the scene mode further includes at least one of ambient lighting environment mode and light show mode; determining the corresponding first lighting effect according to the currently enabled scene mode includes: if the currently enabled scene mode is ambient lighting environment mode or light show mode, then determining the corresponding first lighting effect according to the currently enabled scene mode and the preset correspondence.

[0054] The preset correspondence is pre-defined, including the correspondence between scene modes and the first lighting effect. The first lighting effect differs between ambient light mode and light show mode. The first lighting effect for ambient light mode can be a static display of star patterns, a flashing display of star patterns, or a breathing display of star patterns. The first lighting effect for light show mode can be a dynamic, looping display of multiple patterns, each with a different color and a brightness exceeding the set value.

[0055] The mode switch signals for ambient lighting and light show modes can be obtained by the cockpit domain controller and sent to the trim controller. The mode switch signal can include the scene mode name and switch status information. The scene mode name can be represented by a field name, and the switch status information can be represented by a field value. The mode switch signal for the ambient lighting environment mode when it is on can be `ambientlightmodeSet = 0x2:ON`, where `ambientlightmodeSet` is the scene mode name, specifically indicating the ambient lighting environment mode setting. The mode switch signal for the ambient lighting environment mode when it is off can be `ambientlightmodeSet = 0x1:OFF`. The mode switch signal for the light show mode when it is on can be `lightshowmodeSet = 0x2:ON`, where `lightshowmodeSet` is the scene mode name, specifically indicating the light show mode setting. The mode switch signal for the light show mode when it is off can be `lightshowmodeSet = 0x1:OFF`.

[0056] In this embodiment, there are at least three scene modes: driving mode, ambient lighting mode, and light show mode. These modes can further enhance the visual richness of the driving environment and achieve a personalized cockpit experience for multiple scenarios. Scene modes may also include birthday mode, National Day mode, etc.

[0057] In some embodiments, the luminous ornament control method is executed by the ornament controller, as shown in the reference... Figure 4The trim controller is connected to the cockpit domain controller. The cockpit domain controller is used to respond to the user's touch operation on the virtual switch on the vehicle's central control screen, obtain at least one mode switch signal corresponding to at least one scene mode, and send at least one mode switch signal to the trim controller. The virtual switch corresponds one-to-one with the scene mode.

[0058] Virtual switches refer to switches implemented through a software interface. The virtual switches displayed on the central control screen corresponding to driving modes, ambient lighting modes, and light show modes can be found here. Figure 3 The virtual switch is highlighted when turned on and turns off when turned off. Preferably, there are multiple virtual switches, and their activation logic is mutually exclusive. If one virtual switch is on and another virtual switch is touched, the previous virtual switch will turn off, and the new virtual switch will turn on. In this embodiment, the central control screen has virtual switches corresponding to scene modes, facilitating the activation, switching, and deactivation of scene modes.

[0059] In another embodiment provided in this application, a control system for luminous decorative elements is also provided, referring to... Figure 4 The luminous trim control system includes a cockpit domain controller, a trim controller, and luminous trims. The trim controller is used to execute the aforementioned luminous trim control method.

[0060] Reference Figure 5 and Figure 6 The light-emitting decorative element 10 includes a light-transmitting surface layer 11, a first light guide film 12, a second light guide film 13, a first light source 14, a second light source 15, a substrate 16, and a heat sink 17.

[0061] The light-transmitting surface layer 11 is light-transmitting and has a textured structure, such as wood grain. The light-transmitting surface layer 11 can be formed using INS (in-mold coating) technology. The first light guide film 12 and the second light guide film 13 are located inside the light-transmitting surface layer 11, and both have a light-emitting surface facing the light-transmitting surface layer 11.

[0062] Both the first light guide film 12 and the second light guide film 13 are provided with patterns formed by multiple optical microstructures, and the patterns formed by the optical microstructures on the first light guide film 12 and the second light guide film 13 are different. The first light source 14 and the second light source 15 can be LED light sources, and the LED light sources can include LED lamp beads. After the first light source 14 is lit, it will emit light into the first light guide film 12. After the second light source 15 is lit, it will emit light into the second light guide film 13. The light propagating in the first light guide film 12 and the second light guide film 13 will change its propagation direction after passing through these optical microstructures so that it is emitted from the light-emitting surface and passes through the light-transmitting surface layer 11.

[0063] Optical microstructures refer to structures that affect light transmission performance at the visible or sub-visible wavelength scale. Optical microstructures can be formed through micro-nano imprinting. When using the first light guide film 12 and the second light guide film 13, light propagates within them via total internal reflection before encountering the optical microstructure. Upon encountering the optical microstructure, the total internal reflection is disrupted, causing the light to exit from the light-emitting surface. The light emitted from the light-emitting surface further passes through the light-transmitting surface layer 11, thus displaying the pattern formed by the optical microstructure on the light-emitting element 10.

[0064] When the light-emitting decorative element 10 emits light, it can display a first pattern formed by the first light guide film 12, a second pattern formed by the second light guide film 13, or a third pattern formed by the superposition of the first light guide film 12 and the first light guide film 13.

[0065] The first pattern can be Figure 7 The star pattern shown can be followed by a second pattern. Figure 8 The meteor pattern shown, the third pattern can be Figure 9 The image shows a superimposed star and meteor pattern. The three patterns can be displayed statically or dynamically, such as flowing water, flashing, or breathing.

[0066] In another embodiment provided in this application, a vehicle is also provided, including the aforementioned luminous decorative element control system. The vehicle can be a sedan, commercial vehicle, SUV, SUV, heavy truck, etc. The vehicle can be a new energy vehicle, such as a pure electric vehicle or a hybrid electric vehicle. The vehicle can also be a gasoline-powered vehicle.
