[0020] The present application will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments thereof. However, the present application may be implemented in various forms and should not be construed as being limited to the embodiments given herein. The foregoing embodiments are intended to make the disclosure herein complete and thorough, so as to more fully convey the scope of protection of the present application to those skilled in the art.

[0021] In the context of this application, terms such as “comprising” and “including” indicate that, in addition to having units and steps that are directly and explicitly stated in the specification and claims, the technical solution of this application does not exclude the presence of other units and steps that are not directly or explicitly stated.

[0022] In the context of this application, unless otherwise specified, terms such as “first” and “second” do not indicate the order of the units in terms of time, space, size, etc., but are merely used to distinguish the units.

[0023] In the context of this application, "coupling" should be understood to include situations where electrical energy or electrical signals are directly transmitted between two units, or where electrical energy or electrical signals are indirectly transmitted through one or more intermediate units. In the context of this application, interior lights may include ambient lights, reading lights, interior dome lights, door lights, trunk lights, and rearview mirror lights, etc.

[0024] In the following, various exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings.

[0025] Figure 1 A structural block diagram of a system for controlling interior lights according to one or more embodiments of this application is shown.

[0026] like Figure 1 As shown, the system 100 for controlling the interior lights includes a human-machine interaction module 110, a processing module 120, and a control module 130.

[0027] The human-computer interaction module 110 is configured to receive user-defined vehicle lighting effect control commands and operate as a server to send vehicle lighting effect control commands.

[0028] Optionally, the human-machine interface module 110 can be configured to receive user-defined vehicle lighting effect control commands, package the received commands into a script data packet, and send the script data packet to the processing module 120 via Ethernet using the SOME / IP protocol. In one embodiment, the human-machine interface module 110 can call the SOME / IP service interface to send the script data packet via Ethernet. Ethernet provides a high-speed, reliable communication link, which can meet the transmission needs of complex and diverse user-defined vehicle lighting effect control commands.

[0029] In one embodiment, the human-computer interaction module 110 can be implemented as an in-vehicle central control screen, a voice assistant, or physical buttons, etc. Users can customize the vehicle lighting effect control commands by setting the color, flashing frequency, and brightness of the ambient light, or by customizing the brightness, color, and duration of the reading light.

[0030] The processing module 120 is coupled to the human-computer interaction module 110 and configured to operate as a client to receive headlight effect control commands sent by the human-computer interaction module 110 by subscribing to events that send headlight effect control commands, selectively store the headlight effect control commands to obtain a database of headlight effect control commands, and determine and send headlight effect control commands corresponding to the user operation from the database in response to the user operation.

[0031] In one embodiment, user-defined headlight effect control commands may include color values, brightness values, flashing frequency, duration, headlight effect identifiers (e.g., headlight effect number), interior light types, playback animations (e.g., flashing followed by a gradual change), and playback scenes (e.g., nighttime scene, door unlocking scene, door closing scene, safety warning scene, etc.). Furthermore, user-defined headlight effect control commands can be used to control multiple lights among ambient lights, reading lights, interior dome lights, door lights, trunk lights, and rearview mirror lights, thereby achieving complex and diverse interior light control. Moreover, by customizing playback scenes, the corresponding commands in the headlight effect control command database can be directly called when the playback scene is triggered, enabling headlight effect control without waiting for the vehicle system module to start.

[0032] Optionally, the processing module 120 can be configured to perform service-signal format conversion on the script data packet to obtain a format-converted script data packet, verify the validity of the format-converted script data packet, and selectively store the format-converted script data packet based on the validity verification result. In one embodiment, the processing module 120 can verify whether the structure of the format-converted script data packet conforms to a predefined format, verify whether the parameter values ​​therein are within a reasonable range (e.g., verify whether the color value is between 0-255, verify whether the brightness is between 0-100%), and verify that the data packet has not been tampered with during transmission using methods such as CRC check. When the verification result passes, the format-converted script data packet can be stored. In one embodiment, the processing module 120 can be configured to perform service-signal format conversion on the script data packet to convert the SOME / IP protocol script data packet into a signal format suitable for hardware control, such as LIN bus signals or GPIO signals.

[0033] Optionally, the processing module 120 may include one or more storage areas, each storage area having a headlight effect identifier. The processing module 120 can be configured to detect whether the storage area corresponding to the headlight effect control instruction stores historical headlight effect control instructions based on the headlight effect identifier. When it is detected that the storage area corresponding to the headlight effect control instruction stores historical headlight effect control instructions, the historical headlight effect control instructions can be removed and the headlight effect control instruction can be stored. When it is detected that the storage area corresponding to the headlight effect control instruction does not store historical headlight effect control instructions, the headlight effect control instruction can be stored. Optionally, the processing module 120 can send a successful storage signal to the human-machine interaction module 110 when storing headlight effect control instructions, and send a failed storage signal to the human-machine interaction module 110 when not storing headlight effect control instructions. For example, the storage area can be implemented as a non-volatile memory to ensure that the headlight effect control instructions are not lost after power failure, while supporting the updating and overwriting of headlight effect control instructions. By storing user-defined headlight effect control commands in the processing module 120 to obtain a database of headlight effect control commands, the delay in controlling the interior lights can be reduced.

[0034] Optionally, the processing module 120 can be configured to determine the headlight effect indicator and headlight indicator in response to the user operation, read the headlight effect control command corresponding to the user operation from the storage area corresponding to the headlight effect indicator, and send the read headlight effect control command to the control module 130 corresponding to the headlight indicator. Optionally, the user operation includes the user selecting a headlight effect via the human-machine interaction module 110 and the user operating vehicle components. For example, the user selecting a headlight effect via the human-machine interaction module 110 can be implemented as the user selecting "blue ambient light flashing" or "reading light adjusted to warm color" through the vehicle central control screen, voice assistant, or physical buttons, etc., and the user operating vehicle components can include opening the car door, opening the trunk, playing car music, etc.

[0035] The control module 130 is configured to control the interior lights to display the lighting effect indicated by the lighting effect control command in response to receiving a lighting effect control command corresponding to a user operation.

[0036] According to one or more embodiments of this application, a service-oriented vehicle interior lighting control scheme is proposed. A human-machine interface module receives user-defined lighting effect control commands and operates as a server to send these commands. A processing module operates as a client to receive and store the lighting effect control commands sent by the human-machine interface module by subscribing to events that trigger the sending of these commands. A control module, in response to receiving a lighting effect control command corresponding to a user operation, controls the vehicle interior lights to display the lighting effect indicated by the command. Compared to traditional CAN or LIN protocols, the service-oriented protocol supports higher data throughput, enables the transmission of complex, diverse, and easily updated user-defined lighting effect control commands, reduces control latency, and enhances the in-vehicle atmosphere and user comfort.

[0037] The following will combine Figure 2 This application provides a detailed description of specific implementations of a system for controlling interior lights according to one or more embodiments.

[0038] Figure 2 A structural block diagram of a system for controlling interior lights according to one or more embodiments of this application is shown.

[0039] like Figure 2 As shown, the system 200 for controlling the interior lights includes a human-machine interaction module 210, a processing module 220, and a control module 230. The processing module 220 includes a service-signal conversion submodule 2201, a control submodule 2202, and a storage area 2203. The control module 230 includes a control module for controlling one or more of the ambient lights, reading lights, interior dome lights, door lights, trunk lights, and rearview mirror lights.

[0040] The human-machine interface module 210 is configured to receive user-defined headlight effect control commands and act as a server to send these commands. Optionally, the human-machine interface module 210 can be configured to receive user-defined headlight effect control commands, package the received commands into a script data packet, and send the script data packet to the processing module 220 via Ethernet using the SOME / IP protocol. For example, the human-machine interface module 210 can be configured to encapsulate the received user-defined headlight effect control commands into a structured script data packet using JSON format. For example, the human-machine interface module 210 can be implemented as an in-vehicle central control screen, a voice assistant, or physical buttons.

[0041] The service-signal conversion submodule 2201 is configured to perform service-signal format conversion on the script data packet to obtain a format-converted script data packet, the control submodule 2202 is configured to verify the validity of the format-converted script data packet, and the storage area 2203 is configured to selectively store the format-converted script data packet based on the verification result of the validity of the control submodule 2202.

[0042] In one embodiment, the service-signal conversion submodule 2201 is configured to perform service-signal format conversion on the script data packet to convert the SOME / IP protocol script data packet into a signal format suitable for hardware control, such as a LIN bus signal or GPIO signal. In one embodiment, the control submodule 2202 is configured to verify whether the structure of the format-converted script data packet conforms to a predefined format, verify whether the parameter values ​​therein are within a reasonable range (e.g., verify whether the color value is between 0-255, verify whether the brightness is between 0-100%), and verify that the data packet has not been tampered with during transmission using methods such as CRC check. In one embodiment, the processing module 220 may include one or more storage areas 2203, each storage area 2203 having a vehicle lighting effect identifier for storing user-defined vehicle lighting effect control instructions corresponding to the vehicle lighting effect identifier when the verification by the control submodule 2202 passes.

[0043] In one embodiment, the control submodule 2202 is configured to determine and send a vehicle lighting effect control command corresponding to the user operation from the storage area 2203 in response to the user operation. In another embodiment, the control submodule 2202 is configured to determine a vehicle lighting effect identifier and a vehicle lighting identifier in the user operation, read the corresponding vehicle lighting effect control command from the storage area 2203 corresponding to the vehicle lighting effect identifier in the user operation, and send the read vehicle lighting effect control command to the control module 230 corresponding to the vehicle lighting identifier in the user operation. Exemplarily, the vehicle lighting identifier can be used to identify ambient lights, reading lights, interior dome lights, door lights, trunk lights, rearview mirror lights, etc. Exemplarily, the user operation can include the user selecting a vehicle lighting effect via the human-machine interaction module 210 and the user operating vehicle components. For example, a user operation could be selecting the "blue ambient light flashing" effect via the human-machine interface module 210. The control submodule 2202 can read the corresponding lighting effect control command from the storage area 2203 corresponding to the blue ambient light flashing effect, and send the read lighting effect control command to the control module 230 corresponding to the ambient light via the LIN bus. Similarly, a user operation could be opening a car door. The control submodule 2202 can read the corresponding lighting effect control command from the storage area 2203 corresponding to the door opening light, and send the read lighting effect control command to the control module 230 corresponding to the door light via the LIN bus. Sending the lighting effect control command to the control module 230 via the LIN bus eliminates the need for each interior light control module 230 to have Ethernet communication capabilities, thereby reducing the system cost for controlling the interior lights.

[0044] The control module 230 is configured to control the interior lights to display the lighting effect indicated by the lighting effect control command when a lighting effect control command corresponding to a user operation is received. For example, if the user operation is to select the lighting effect "blue ambient light flashing" via the human-machine interaction module 210, the control module 230 can control the ambient light to display a blue flashing effect.

[0045] Figure 3 A flowchart illustrating a method for controlling interior lights according to one or more embodiments of this application is shown. Figure 3 The method shown can be achieved by using the above Figure 1 or Figure 2 The system shown is used to control the interior lights.

[0046] like Figure 3 As shown, in step S301, the human-computer interaction module receives user-defined vehicle lighting effect control commands and operates as a server to send vehicle lighting effect control commands.

[0047] In step S303, the processing module operates as a client to receive the headlight effect control command sent by the human-machine interaction module by subscribing to the event of sending headlight effect control command, selectively stores the headlight effect control command to obtain a database of headlight effect control commands, and determines and sends the headlight effect control command corresponding to the user operation from the database in response to the user operation.

[0048] In step S305, the control module responds to receiving a vehicle lighting effect control command corresponding to the user's operation by controlling the interior lights to display the vehicle lighting effect indicated by the vehicle lighting effect control command.

[0049] According to one aspect of this application, a service-oriented vehicle interior lighting control scheme is proposed. A human-machine interface module receives user-defined lighting effect control commands and operates as a server to send these commands. A processing module operates as a client to receive and store the lighting effect control commands sent by the human-machine interface module by subscribing to events that trigger the sending of these commands. A control module, in response to receiving a lighting effect control command corresponding to the user's operation, controls the vehicle interior lights to display the lighting effect indicated by the command. Compared to traditional CAN or LIN protocols, the service-oriented protocol supports higher data throughput, enables the transmission of complex, diverse, and easily updated user-defined lighting effect control commands, reduces control latency, and enhances the in-vehicle atmosphere and user comfort.

[0050] Alternatively, this application can also be implemented as a computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform a method for controlling interior lights according to one aspect of this application.
