In some embodiments, the controller 100 may be a vehicle domain controller.

The in-vehicle terminal 200 is used for providing various entertainment functions and services.

In some embodiments, the vehicle-mounted terminal 200 is specifically configured to send a first control instruction to the interaction light processor 300 through the CAN bus, so that the interaction light processor 300 determines a target image from a plurality of images stored in the interaction light processor 300 according to an image identifier of the target image, and lights a light source corresponding to the target image; wherein the plurality of images are transmitted to the interactive lamp processor 300 through the ethernet by the in-vehicle terminal 200.

Illustratively, the MCU of the vehicle-mounted terminal 200 sends a first control instruction to the interactive lamp processor 300 through the CAN bus, so that the interactive lamp processor 300 determines a target image from a plurality of images stored in the interactive lamp processor 300 according to the image identifier of the target image, and lights a lamp source corresponding to the target image.

Wherein the plurality of images are transmitted to the interactive lamp processor 300 through the ethernet by the in-vehicle terminal 200.

In some embodiments, the interactive lamp processor 300 includes: steering lamps, brake lamps, front and rear headlamps, width lamps, fog lamps, reversing lamps, warning lamps, light modules in the vehicle and the like.

It will be appreciated that in various embodiments, the interactive light processor 300 may be one or more, and embodiments of the present application are not limited in this regard.

It will be appreciated that as shown in fig. 2, a method for calculating the load rate of a single frame is provided. For a standard frame of controller area network variable data rate (CANFD) that supports a maximum of 64 bytes (byte) of data, the actual length of each frame is 572 bits (bits) per frame sent.

Wherein for a frame structure of a CANFD standard frame, the 29bit arbitration segment is calculated using a rate of 500 Kbps. Specifically, 29 bits include in common: 1-bit SOF segment+12-bit arbitration segment+1-bit IDE segment+1-bit FDF segment+1-bit R0 segment+1-bit BRS segment+2-bit ACK segment+7-bit EOF segment+3-bit frame interval. Wherein the bit time of one bit is 1/((500×1000)/1000000000) =2000 ns, and the load factor of the 29 bits in a single frame is ((29×2000 ns)/1 s) ×100% =0.0058%.

For the frame structure of a CANFD standard frame, 543 bits of the data segment are calculated using a rate of 2 Mbps. Specifically, 543 bits include in common: 1-bit ESI section+4-bit DLC section+512-bit data section+26-bit CRC section. Wherein, the bit time of one bit is 1/((2×1000000)/1000000000) =500 ns, and the loading rate of the 543bit in a single frame is ((543×500 ns)/1 s) ×100% = 0.02715%.

So the loading of one CANFD standard frame is 0.0058% +0.02715% = 0.03295%. Taking an example that the interactive lamp consists of 3000 LED single-color lamp beads, and each lamp bead uses 8bit data to represent the brightness of the lamp bead (the brightness of the lamp bead takes a gradient of 0-100 percent as a gradient). If the CANFD standard frame is used for transmission, 3000/64 approximately 47 frames of data of one picture need to be transmitted, if the period is 20ms, the load rate is (1000 ms/20 ms) × 0.03295% ×47 approximately 77.43%, and the load rate is far higher than the optimal load rate of the CAN bus by 30%. At this time, if the optimum load factor for the CAN bus is 30%, the period is calculated as N: (1000/N) × 0.03295% ×47=30%, resulting in n≡52ms, so that data transmission of a single picture requires 52ms×47=2444 ms; for ethernet, the actual length of each frame transmitted may be 1500 bytes, so if the ethernet is used to transmit a picture, 3000/1500=2 frames need to be transmitted to transmit the data of the single picture, and the data transmission of the single picture needs only 52ms by 2=104 ms, which is far less than the transmission time of the CANFD standard frame.

Fig. 3 is a schematic diagram of a light management method according to an embodiment of the present application, which is applied to a vehicle-mounted terminal of a vehicle; the vehicle-mounted terminal is connected with the interactive lamp processor of the vehicle through a Controller Area Network (CAN) bus and an Ethernet; the CAN bus is used for transmitting control instructions, and the Ethernet is used for transmitting data; the method comprises steps S101-S102.

S101, generating a first control instruction.

The first control instruction comprises an image identifier of the target image; the first control instruction is used for controlling the interactive lamp processor to light the lamp source corresponding to the target image.

As a possible implementation manner, before the step S101, the method further includes: and receiving a scene trigger instruction sent by the controller.

The scene triggering instruction is used for indicating the vehicle-mounted terminal to trigger the light effect corresponding to the target scene.

In some embodiments, a functional module is included in the controller; the function module is used for identifying the corresponding function scene.

Illustratively, the greeting function module is configured to identify a greeting scene.

As one possible implementation manner, after the functional module in the controller identifies the corresponding functional scene, it is detected whether the condition that the interactive lamp displays the formulated pattern is satisfied, if so, a scene triggering instruction is sent to the vehicle-mounted terminal through the CAN bus, so that the vehicle-mounted terminal triggers the light effect corresponding to the target scene according to the scene triggering instruction.

It will be appreciated that in some embodiments, the controller and the interactive lamp processor may communicate via a CAN bus.

Wherein the customized ethernet data format is as shown in fig. 7, and the format of the image data in the customized ethernet data format is as shown in fig. 8.

For example, when the on-vehicle terminal establishes an ethernet transmission channel with the interactive light processor and then sequentially transmits N video frames to the interactive light processor, if the pattern type of the image data is 0x03, it indicates that the N video frames are directly displayed and not stored.

It can be understood that, unlike the method that the vehicle-mounted terminal in the related art sends N video frames to the interactive lamp processor through the LVDS interface after receiving the second trigger operation, the method provided by the embodiment of the application does not use the LVDS interface, and sends N video frames to the interactive lamp processor in turn through the ethernet, so that the transmission rate can be ensured, real-time sending and displaying (real-time enabling the interactive lamp processor to display the corresponding video stream or lyric caption, etc.) of the interactive lamp processor can be achieved, the use feeling of a user can be improved, and meanwhile, the harness cost of the vehicle can be reduced.

It CAN be appreciated that compared with the related art that the interactive lamp processor is not directly connected with the vehicle-mounted terminal, in the method provided by the application, the interactive lamp processor receives the first control instruction sent by the vehicle entertainment terminal through the CAN bus, so that the vehicle-mounted terminal CAN directly transmit the control instruction to the interactive lamp processor, the time for transmitting the control instruction is reduced, and the instantaneity for transmitting the control instruction is improved. Meanwhile, in the method provided by the application, the interactive lamp processor receives the image sent by the vehicle-mounted terminal through the Ethernet, so that the image transmission efficiency can be improved, and when the transmitted image is complex and the data volume is large, the transmission time is shortened, and the use experience of a user is improved.

S501, receiving an image sent by the vehicle-mounted terminal through the Ethernet.

In some embodiments, after receiving an image sent by the vehicle-mounted terminal, the interactive lamp processor first identifies a pattern type of the image, and performs a corresponding operation on the image according to the pattern type.

For example, when the pattern type is newly added and saved, the interactive light processor will newly add the image to the database and save it.

In some embodiments, the specific implementation of the step S501 may refer to the step S203, and the embodiments of the present application are not described herein.

S502, configuring an image identifier for the image, and sending the image identifier of the image to the vehicle-mounted terminal.

In some embodiments, when the pattern type is newly added and saved or modified and saved, the interactive lamp processor performs an operation corresponding to the pattern type, then configures an image identifier for the image, and sends the image identifier of the image to the vehicle-mounted terminal.

It can be understood that after receiving the image sent by the vehicle-mounted terminal, the image identifier corresponding to the image is returned; each image corresponds to a unique identifier, so that the vehicle-mounted terminal can conveniently manage the images and the image identifiers, and the image identifiers of the target images are placed into the first control instruction when the vehicle-mounted terminal needs to control the interaction lamp processor to display the light effect corresponding to the target images.

In some embodiments, as shown in fig. 12, the method further comprises: steps S601 to S602.

In some embodiments, after receiving N video frames sent by the vehicle-mounted terminal, the interactive light processor first identifies a pattern type of each video frame, and performs a corresponding operation on the N video frames according to the pattern type.

For example, when the pattern type is direct display and not save, the interactive light processor will sequentially illuminate the light source corresponding to each of the N video frames and not save the N video frames.

It can be understood that the interactive lamp processor does not need to receive video frames through the LVDS interface, but lights the lamp sources corresponding to each video frame in the N video frames in turn after receiving the N video frames through the Ethernet, so that the harness cost of the vehicle can be reduced while the transmission rate is ensured.

The above light management method provided by the application is to be understood conveniently, and the specific implementation manner of the light management method is described in the form of an embodiment.

And b5, the interactive lamp processor generates an image identifier of the image and returns the image identifier to the vehicle-mounted terminal.

And b6, the vehicle-mounted terminal receives and stores the image identification.

In some embodiments, in order to better understand the necessity of separately transmitting the image and the control command in the light management method provided by the present application, a greeting scene is taken as an example, and the whole process of the light management method is specifically described below.

Specifically, as shown in fig. 15, the light management method of the welcome scene may be implemented as the following steps:

step c1, the vehicle-mounted terminal wakes up the SOC, and a user opens an image editing interface to edit the welcome image.

And c2, responding to a holding request of a user by the vehicle-mounted terminal, and generating a welcome image according to an image analysis and generation technology. Wherein, the welcome image is composed of one or more frames.

Step c3, the vehicle-mounted terminal sends the welcome image to the interactive lamp processor; the vehicle-mounted terminal and the interactive lamp processor transmit images through the Ethernet.

And c4, the interactive lamp processor receives and stores the welcome image sent by the vehicle-mounted terminal, and simultaneously generates an image identifier of the welcome image.

And c5, the interactive lamp processor sends the image identification to the vehicle-mounted terminal.

And c6, the vehicle-mounted terminal receives and stores the image identification.

And c7, waking up the controller after the key detection module of the controller detects the key.

And c8, judging whether the wake-up condition of the greeting scene is met by the greeting functional module in the controller.

And step c9, under the condition that the wake-up condition of the welcome scene is met, the power management module powers on the vehicle-mounted terminal and the interactive lamp processor.

If the wake-up condition of the welcome scene is not met, the light management method is ended.

Step c10, a network management module in the controller sends a first CAN message to the vehicle-mounted terminal; the first CAN message is used for waking up the MCU in the vehicle-mounted terminal.

Step c11, the vehicle-mounted terminal sends a second CAN message to the interaction lamp processor; the second CAN message is used for waking up the interactive lamp processor.

And c12, the controller puts the image identification of the welcome image corresponding to the welcome scene into a scene wake-up instruction.
