[0034] Example 1 The specific implementation is as follows: like Figure 1 As shown, it is a schematic diagram of the structure of a high-pixel vehicle light control system based on CANFD communication provided in this embodiment.

[0035] As an example, the high-pixel headlight control system includes: a body 1 and a headlight system 2, wherein the body 1 is provided with a body controller 100, and the headlight system 2 is integrated with a headlight controller 200 and an optical module 210; the body controller 100 is connected to the headlight controller 200 via CANFD communication, CAN communication and hard-wire communication, and the body controller 100 is used to send CANFD messages, CAN messages and / or hard-wire signals to the headlight controller 200; the headlight controller 200 is used to parse the received CANFD messages, CAN messages and / or hard-wire signals, and control the action of the optical module 210 based on the parsing results; the headlight controller 200 is also used to realize the network control of the vehicle based on the parsing results of the CAN messages and KL15 hard-wire signals. Network management function; and / or the light controller 200 is also used to parse the CANFD message carrying the light control instruction, and execute the lighting, extinguishing and complex lighting effect projection actions of the optical module 210 based on the analysis result; and / or the light controller 200 is also used to parse the hard-wire signal carrying the control instruction of the turn signal and the brake light, and execute the control action of the turn signal and the brake light of the optical module 210 based on the analysis result; and / or the light controller 200 is also used to store the picture or video image contained in the CANFD message based on the analysis result of the CANFD message; and / or the light controller 200 is also used to parse and respond to the diagnostic message contained in the CANFD message to complete the storage and management function of the diagnostic fault. Specifically, the headlights controlled by the control scheme are high-pixel headlights, which contain at least 1,000 LED lamp beads, including but not limited to ADB, ISD, projection headlights, etc. The headlight system is powered by the body, receives CANFD, CAN message signals and hard-wire signals from the body controller 100, and controls the headlight functions based on them, mainly including network management, UDS diagnosis, OTA upgrade, lighting control, etc. Among them, CAN messages are used to control the network management function of the lamps; the remaining functions are controlled by CANFD signals; hard-wire signals are used as redundant designs to ensure the synchronization and functional safety of left and right or front and rear lamps.

[0036] In some feasible embodiments, combined with Figure 3 As shown, the optical module 210 includes a high-pixel headlight area 2101 and a functional headlight area 2102; the functional headlight area 2102 is used to meet the lighting and extinguishing functions of regulatory functional lamps; the high-pixel headlight area 2101 is used to cooperate with the functional headlight area to achieve complex lighting effects and meet customer needs for intelligent interaction.

[0037] In some feasible implementations, the power provided by the vehicle body 1 to the vehicle light system 2 is normal power, and the vehicle light controller 200 is required to implement the network management function according to the network management message and the KL15 hard-wire signal to achieve energy saving. The network management message is in the format of a CAN message to save space. The network management follows the network management process of the AUTOSAR standard, so that the solution can be well adapted to all models that follow the AUTOSAR standard.

[0038] In some feasible embodiments, combined with Figure 2 As shown, the headlight controller 200 integrates an LED driving module 2001, a power module 2002, an MCU module 2003, an SBC module 2004 and a storage module 2005; the SBC module 2004 is used to realize CANFD communication and CAN communication between the body controller 100 and the headlight controller 200; the MCU module 2003 is communicatively connected with the LED driving module 2001, and is used to convert the headlight control signal into a UART signal to control the action of the optical module 210; the power module 2002 is used to provide a working voltage for the headlight controller 200; the storage module 2005 is used to store the image or video data sent by the body controller 100.

[0039] In some feasible implementations, the conventional regulatory functions of the headlights are controlled by combining CANFD messages and hard wires. The body controller 100 sends a CANFD message carrying a lamp control instruction to the headlight controller 200. The headlight controller 200 performs corresponding lamp control actions including lighting and extinguishing of the headlights according to the received message signal. At the same time, the headlight controller 200 reports the real-time lighting status of the lamp, software and hardware version information, detected faults, etc. to the body end through a message. Among them, the hard wire signal mainly involves turn signals and brake lights. Since the hard wire signal has higher stability and timeliness than the message signal, the functional safety-related functions such as turn signals and brake lights that have higher synchronization requirements are synchronously controlled by combining messages and hard wire signals.

[0040] In some feasible implementations, the control of various complex lighting effects of high-pixel headlights is mainly completed by CANFD messages. According to different requirements, a certain amount of high-pixel light patterns and videos are pre-stored in the lamp software and presented as preset lighting effects. The lamp software program includes two parts: BOOTLOADER program and APP program. The headlight controller is also used to receive upgrade-related diagnostic commands sent by the diagnostic platform when there is a need for OTA upgrade. Specifically, the high-pixel headlight control system also includes a client 3, and the client 3 is used to interconnect with the vehicle body, so that the headlight system can display user-defined lighting effects in real time through the vehicle body controller. That is, in order to realize the function of intelligent interaction, it also supports terminal users to switch to non-preset effects in real time through large screens or mobile phones and other devices.

[0041] In some feasible implementations, the vehicle light controller is also used for transmitting the picture or video data to the vehicle light controller 200 in advance by means of CANFD messages during the normal operation of the vehicle light, and storing the picture or video data in the storage module 2005. Specifically, for pictures or videos that occupy a large space, during the normal operation of the vehicle light, the vehicle body controller 100 supports transmitting the data to the vehicle light controller 200 in advance by means of CANFD messages, and storing the data in the external storage module 2005 of the vehicle light controller 200, so as to ensure that there is no jamming when the lighting effect is actually executed.

[0042] In some feasible implementations, the body controller 100 is connected to an external diagnostic platform 4, and the body controller 100 transmits the diagnostic message sent by the diagnostic platform 4 to the headlight controller 200 through CANFD communication. The headlight controller 200 parses and responds to the diagnostic message contained in the CANFD message to complete the storage and management functions of the diagnostic fault. Further, the headlight controller 200 is also used to receive the upgrade-related diagnostic command sent by the diagnostic platform 4 when there is an OTA upgrade requirement; when it is determined that the upgrade conditions are met, it jumps from the normally working APP program to the BOOTLOADER program, performs the upgrade-related operations, and stores the APP program files that need to be updated in the MCU module 2003. Specifically, the headlight controller 200 also supports standard UDS diagnosis and supports OTA upgrades based on UDS diagnosis. This solution can parse and respond to the CANFD format diagnostic message sent by the external diagnostic platform, such as the OTA platform, to complete the storage and management functions of the diagnostic fault. When there is an OTA upgrade requirement, the diagnostic platform sends the upgrade-related diagnostic command to the headlight through the agreed upgrade process. When the car light controller 200 receives the upgrade instruction, the upgrade condition is met, that is, the normal working APP program jumps to the BOOTLOADER program, and the relevant operations of the upgrade are performed, and the APP program files to be updated are stored in the MCU, wherein the upgrade condition is a preset judgment condition, such as a preset vehicle speed condition, a voltage range, etc., to avoid OTA upgrades under unsafe working conditions. Since the pixels of the car light are relatively high, the pictures and video files required to present the lighting effects are relatively large, and there is also a situation where the preset data needs to be updated through OTA upgrade. This situation is similar to the upgrade of the APP program in that both use BOOTLOADER to update the data. The difference is that the upgrade of the APP program is to store the program data to be upgraded in the code memory of the MCU, while the upgrade of pictures and videos is to store the data to be upgraded directly in the external storage module of the car light without passing through the APP for use by the APP. Compared with the use of CAN messages to transmit data, the use of CANFD messages to transmit data can increase the amount of data transmitted in a single transmission, further improve the data transmission efficiency, and also ensure that the projection effect of the car light can be guaranteed under the condition of high-pixel car lights.

[0043] The above embodiment introduces the CANFD bus on the basis of the original bus, and adopts a communication method that combines CANFD, CAN and hard-wired communication to achieve flexible control of high-pixel headlights, so that the high-pixel headlights can present a variety of lighting effects and provide intelligent interactive functions, which is more suitable for the requirements of the technological era for energy saving, high efficiency, and intelligence of automobiles.

[0044] It is worth mentioning that all modules involved in this embodiment are logical units. In practical applications, a logical unit can be a physical unit, a part of a physical unit, or a combination of multiple physical units.
