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

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

[0028] Optionally, the human-computer interaction module 110 may be configured to receive a user-defined vehicle light effect control instruction, package the received vehicle light effect control instruction 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-computer interaction module 110 may call the SOME / IP service interface to send the script data packet via Ethernet. Ethernet provides a high-speed, reliable communication link that can meet the transmission requirements of complex and diverse vehicle light effect control instructions defined by users.

[0029] In one embodiment, the human-computer interaction module 110 can be implemented as a vehicle-mounted central control screen, a voice assistant or physical buttons, etc. Users can customize the vehicle light effect control instructions by setting the color, flashing frequency, brightness of the ambient light or 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 is configured to operate as a client to receive the headlight effect control instruction sent by the human-computer interaction module 110 by subscribing to the event of sending the headlight effect control instruction, selectively store the headlight effect control instruction to obtain a database of the headlight effect control instruction, and determine and send the headlight effect control instruction corresponding to the user operation from the database in response to the user operation.

[0031] In one embodiment, the user-defined car light effect control instructions may include color value, brightness value, flashing frequency, duration, car light effect identification (such as car light effect number), interior light type, playback animation (for example, flashing first and then gradually changing), playback scene (for example, night scene, unlock door scene, close door scene, safety warning scene, etc.), etc., and the user-defined car light effect control instructions can be used to control multiple lights including ambient light, reading light, interior ceiling light, door light, trunk light, and rearview mirror light, so as to realize complex and diverse interior light control, and by customizing the playback scene, the corresponding instructions in the database of car light effect control instructions can be directly called when the playback scene is triggered, and the car light effect control can be realized without waiting for the vehicle computer 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 the predefined format, verify whether the parameter value therein is within a reasonable range (for example, 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 by methods such as CRC verification, and the format-converted script data packet can be stored when the verification result passes. In one embodiment, the processing module 120 can be configured to perform service-signal format conversion on the script data packet to convert the script data packet of the SOME / IP protocol into a signal format suitable for hardware control, such as a LIN bus signal or a GPIO signal.

[0033] Optionally, the processing module 120 may include one or more storage areas, each storage area having a headlight effect identifier, and the processing module 120 may be configured to detect whether the storage area corresponding to the headlight effect control instruction stores a historical headlight effect control instruction based on the headlight effect identifier.

Optionally, the processing module 120 may feed back a storage success signal to the human-computer interaction module 110 when storing the headlight effect control instruction, and feed back a storage failure signal to the human-computer interaction module 110 when not storing the headlight effect control instruction. Exemplarily, the storage area may be implemented as a non-volatile memory to ensure that the headlight effect control instruction is not lost after power failure, while supporting the update and overwriting of the headlight effect control instruction. By storing the user-defined vehicle light effect control instructions in the processing module 120 to obtain a database of vehicle light effect control instructions, the delay in controlling the interior lights can be reduced.

Compared with traditional CAN or LIN protocols, service-oriented protocols support higher data throughput, can realize the transmission of complex, diverse and easy-to-update light effect control instructions that are customized by users, reduce control delays, and improve the interior atmosphere and user comfort.

[0039] like Figure 2 As shown in the figure, the system 200 for controlling the interior lights of a vehicle includes a human-computer 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 light, reading light, interior ceiling light, door light, trunk light and rearview mirror lighting.

[0040] The human-computer interaction module 210 is configured to receive user-defined car light effect control instructions and operate as a server to send car light effect control instructions. Optionally, the human-computer interaction module 210 can be configured to receive user-defined car light effect control instructions, package the received car light effect control instructions into a script data packet, and send the script data packet to the processing module 220 via Ethernet using the SOME / IP protocol. Exemplarily, the human-computer interaction module 210 can be configured to encapsulate the received user-defined car light effect control instructions into a structured script data packet using the JSON format. Exemplarily, the human-computer interaction module 210 can be implemented as a vehicle-mounted central control screen, a voice assistant, or a physical button, etc.

[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 validity verification result 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 script data packet of the SOME / IP protocol into a signal format suitable for hardware control, such as a LIN bus signal or a 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 the predefined format, verify whether the parameter value therein is within a reasonable range (for example, 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 by methods such as CRC verification. In one embodiment, the processing module 220 may include one or more storage areas 2203, each storage area 2203 having a headlight effect identifier, for storing a user-defined headlight effect control instruction corresponding to the headlight effect identifier when the verification of the control submodule 2202 is passed.

[0043] In one embodiment, the control submodule 2202 is configured to determine and send a headlight effect control instruction corresponding to the user operation from the storage area 2203 in response to the user operation.

Exemplarily, the headlight identifier can be used to identify the atmosphere light, reading light, interior ceiling light, door light, trunk light, rearview mirror lighting, etc. Exemplarily, the user operation can include the operation of the user selecting the headlight effect via the human-computer interaction module 210 and the user's operation on the vehicle components. For example, the user operation may be to select the car light effect "blue ambient light flashing" via the human-computer interaction module 210, and the control submodule 2202 may read the corresponding car light effect control instruction from the storage area 2203 corresponding to the blue ambient light flashing, and send the read car light effect control instruction to the control module 230 corresponding to the ambient light via the LIN bus. For example, the user operation may be to open the car door, and the control submodule 2202 may read the corresponding car light effect control instruction from the storage area 2203 corresponding to opening the car door light, and send the read car light effect control instruction to the control module 230 corresponding to the car door light via the LIN bus. By sending the car light effect control instruction to the control module 230 via the LIN bus, it is not necessary for the control module 230 of each interior light to have Ethernet communication capability, thereby reducing the cost of the system for controlling the interior light.

[0044] The control module 230 is configured to control the interior lights to present the light effects indicated by the light effect control instructions in response to receiving the light effect control instructions corresponding to the user operation. For example, the user operation may be to select the light effect "blue ambient light flashing" via the human-computer interaction module 210, and the control module 230 may control the ambient light to present the blue flashing effect.
