[0002] With the development of intelligent and interactive automobiles, more and more automobile parts have been innovated with intelligent concepts to keep up with the development trend of automobiles. In terms of exterior decoration, more and more products with intelligent interaction have been born. In terms of lighting, there are digital projection headlights, intelligent taillight interactive lights, and intelligent welcome interactive lights. Combined with the increasing number of cameras and radar products on cars, as well as more humane and personalized pattern displays, the development of intelligent interaction has entered a new chapter.
[0003] In order to better realize human-machine interactive display, the function of vehicle lights has also evolved from single lighting to intelligent and emotional, and Intelligent Signal Display (ISD) technology has emerged. The principle of ISD intelligent interaction is to use a large number of LED light sources to communicate with the outside world through programming. At present, vehicle interactive lights have the following problems: single form of expression, for example, headlights can only play the role of lighting, turn signals can only indicate turning or emergency, and cannot directly convey the information that the driver wants to express to the outside world, and the lights lack the experience of human-vehicle interaction. Summary of the invention
[0004] The purpose of the present invention is to provide an ISD interactive light pattern control system and a vehicle, which utilizes an interactive light pattern that is independently selected or edited to intuitively convey the intentions of the driver and passengers to the outside world and improve the human-vehicle interaction experience.
[0005] To achieve the above object, the present invention provides the following technical solutions: An ISD interactive light pattern control system, comprising: an infotainment system, a body domain control system and an interactive light control system; The infotainment system is used to generate a target vehicle light pattern to be displayed, send a pattern sending instruction and a pattern display instruction; The target vehicle light pattern is a pattern selected from the ISD interactive light library or a custom pattern, and the pattern sending instruction is used to send data frames of the target vehicle light pattern to the interactive light control system through the vehicle body domain control system, each data frame contains the on / off data of the pixel points of a part of the target vehicle light pattern, and sends the pattern display instruction according to the message that the interactive light control system successfully receives the data fed back by the vehicle body domain control system; The body domain control system is respectively connected to the infotainment system and the interactive light control system for communication, and is used to forward the data frame of the target light pattern to the interactive light control system, and to forward the pattern display instruction to the interactive light control system; The interactive light control system includes at least one ISD interactive light controller, which is used to receive the data frame of the target vehicle light pattern according to the ID information of the ISD interactive light, verify the data frame of the target vehicle light pattern, store the data frame that passes the verification in a cache area, return a message of successful data reception to the vehicle body domain control system after all data frames pass the verification, and control the LED lights corresponding to the pixel points of the target vehicle light pattern on the light screen of the ISD interactive light to light up according to the pattern display instruction to display the target vehicle light pattern.
[0006] Further, the infotainment system includes a vehicle light pattern generation module; The headlight pattern generation module is used to call a pre-saved pattern from the ISD interactive light library as a target headlight pattern, and is also used to respond to a user's editing instruction, autonomously edit pattern information in an editing interface as a target headlight pattern, and save it to the ISD interactive light library.
[0007] Further, based on the pattern sending instruction, the pattern sending instruction is specifically used to send the data frame of the target vehicle light pattern according to a preset sending cycle and sending times.
[0008] Furthermore, the sending of the data frame of the target vehicle light pattern according to a preset sending cycle and sending times includes: Encapsulating the on / off data of all pixels of the target vehicle light pattern into a plurality of data frames, and identifying them by frame index numbers; During the data frame transmission process, the same data frame is continuously transmitted three times at a fixed period in the order of the frame index numbers before the next data frame is transmitted.
[0009] Furthermore, the ISD interactive light controller verifies the data frame of the target vehicle light pattern, including: Determine whether the number of received data frames is the same as the number sent; If the number of received data frames is the same as the number sent, determine whether the current data frame is the same as the last received data frame based on the frame index number; If the current data frame is identical to the data frame received last time, the current data frame passes the verification and the data frame received last time is deleted.
[0010] Further, judging whether the current data frame is the same as the last received data frame based on the frame index number includes: Identify the frame index number of the current data frame, and determine whether the frame index number of the current data frame is the same as the frame index number of the data frame received last time; If so, determining whether the on / off data of at least one pixel in the current data frame is the same as that in the last received data frame; If the on / off data of at least one pixel in the current data frame is the same as that in the last received data frame, it is determined that the current data frame is the same as the last received data frame.
[0011] Furthermore, if the ISD interactive light controller determines that the number of received data frames is different from the number sent or determines based on the frame index number that the current data frame is different from the last received data frame, the current data frame is discarded and a message of data reception failure is returned to the infotainment system through the body domain control system. The message of data reception failure is used to instruct the infotainment system to resend the data frame of the target headlight pattern.
[0012] Furthermore, the ISD interactive light controller is also used to convert the data frame that has passed the inspection into a data format that is supported for display by the interactive light driver chip.
[0013] Furthermore, the ISD interactive light controller is also used to feed back the display status of the target vehicle light pattern to the infotainment system through the vehicle body domain control system.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] In order to solve the deficiencies of the prior art, the present invention discloses an ISD interactive light pattern control system, such as Figure 1 As shown, the system includes: an infotainment system, a body domain control system and an interactive light control system.
[0021] The infotainment system is used to generate a target headlight pattern to be displayed, send a pattern sending instruction and a pattern display instruction.
[0022] Among them, the target vehicle light pattern is a pattern selected from the ISD interactive light library or a custom pattern, and the pattern sending instruction is used to send data frames of the target vehicle light pattern to the interactive light control system through the vehicle body domain control system, each data frame contains the on and off data of pixel points in a partial area of the target vehicle light pattern, and the pattern display instruction is sent according to the message that the interactive light control system successfully receives the data fed back by the vehicle body domain control system.
[0023] The body domain control system is respectively connected to the infotainment system and the interactive light control system for communication, and is used to forward the data frame of the target vehicle light pattern to the interactive light control system, and to forward the pattern display instruction to the interactive light control system.
[0024] The interactive light control system includes at least one ISD interactive light controller, which is used to receive the data frame of the target vehicle light pattern according to the ID information of the ISD interactive light, verify the data frame of the target vehicle light pattern, store the data frame that passes the verification in a cache area, return a message of successful data reception to the vehicle body domain control system after all data frames pass the verification, and control the LED lights corresponding to the pixel points of the target vehicle light pattern on the light screen of the ISD interactive light to light up according to the pattern display instruction to display the target vehicle light pattern.
[0025] In actual applications, the in-vehicle infotainment system is an in-vehicle comprehensive information processing system that uses a dedicated in-vehicle central processor, based on the body bus system and Internet services. It can realize a series of applications including three-dimensional navigation, real-time traffic conditions, Internet TV IPTV, assisted driving, fault detection, vehicle information, body control, mobile office, wireless communication, online entertainment functions and TSP services.
[0026] In the embodiment of the present invention, the human-computer interaction module of the infotainment system generates the target light pattern to be displayed by each ISD interactive light of the vehicle. By selecting a pattern from the ISD interactive light library or a custom pattern as the target light pattern, in the interactive light control system, the ISD interactive light controller is used to control the corresponding ISD interactive light to display the target light pattern, thereby intuitively conveying the intention of the driver and passengers to the outside world and enhancing the sense of human-computer interaction. In the embodiment of the present invention, ISD interactive lights with different IDs can display different light patterns to improve the fun. The ISD interactive light is a matrix light screen formed by multiple LED lights. The number of pixels on the large screen of the infotainment system corresponds to the number of LEDs of the ISD interactive light. The on and off data of all pixels of the target light pattern are partitioned and encapsulated into several data frames for transmission to improve data fault tolerance. In addition, the ISD interactive light controller stores the verified data frame in the buffer area before displaying it to prevent the light pattern from being incompletely displayed or displaying incorrectly due to errors in the data transmission process, thereby ensuring the stable display of the light pattern.
[0027] In an embodiment of the present invention, the infotainment system includes a headlight pattern generation module, which is used to call a pre-saved target headlight pattern from the ISD interactive light library, and the pattern can be a static pattern or a dynamic pattern. Further, the headlight pattern generation module is also used to respond to the user's editing instruction, autonomously edit the pattern information in the editing interface as the target headlight pattern, and save it to the ISD interactive light library.
[0028] In the infotainment system, the pattern sending instruction is specifically used to send the data frame of the target vehicle light pattern according to a preset sending cycle and sending times.
[0029] According to a preferred embodiment of the present invention, the method of sending the data frame of the target headlight pattern according to a preset sending period and number of sendings includes: encapsulating the on and off data of all pixels of the target headlight pattern into a plurality of data frames, identifying them by frame index numbers, each data frame containing the on and off data of pixels of a partial area of the target headlight pattern; in the process of sending the data frames, sending the same data frame three times in a fixed period in succession according to the order of the frame index numbers, and then sending the next data frame.
[0030] The data frame described in the embodiment of the present invention can be understood as a data message. The target headlight pattern displays pattern information through the on / off data of all pixels on the large screen. The large screen is divided into several areas. The on / off data of the pixels in each area are used to display part of the pattern information. Each area corresponds to a specific LED light range on the light screen of the ISD interactive light. The pixel on / off data in each area is encapsulated into a data frame to obtain several data frames of the target headlight pattern. Each data frame carries a frame index number as an identifier. These several data frames form a complete headlight pattern when displayed on the light screen display end controlled by the ISD interactive light controller. In order to improve the accuracy of data transmission, the infotainment system sends the same data frame three times in a row according to a fixed period before sending the next data frame.
[0031] In an embodiment of the present invention, after the ISD interactive light controller receives the data frame of the target vehicle light pattern according to the ID information of the ISD interactive light, it is also necessary to verify the data frame of the target vehicle light pattern, including: determining whether the number of received data frames is the same as the number sent; if the number of received data frames is the same as the number sent, determining whether the current data frame is the same as the last received data frame based on the frame index number; if the current data frame is the same as the last received data frame, the current data frame passes the verification and the last received data frame is deleted.
[0032] According to a specific embodiment of the present invention, the determining whether the current data frame is the same as the last received data frame based on the frame index number specifically includes: identifying the frame index number of the current data frame, and determining whether the frame index number of the current data frame is the same as the frame index number of the last received data frame; if so, it means that the current data frame and the last received data frame are the same data frame that are repeatedly sent, and then determining whether the on and off data of at least one pixel in the current data frame and the last received data frame are the same; if the on and off data of at least one pixel in the current data frame and the last received data frame are the same, then determining that the current data frame is the same as the last received data frame, indicating that the data frame that is repeatedly sent twice has not changed during the transmission process, that is, the current data frame is valid and the check passes.
[0033] Furthermore, if it is determined that the number of received data frames is different from the number sent or if it is determined based on the frame index number that the current data frame is different from the last received data frame, it means that the data frame is lost during the transmission process or the content of the data frame sent twice has changed. In this case, the current data frame is discarded and a message of data reception failure is returned to the body domain control system. The message of data reception failure is used to instruct the infotainment system to resend the data frame of the target headlight pattern.
[0034] It should be noted that the repeatedly sent identical data frames are verified, and the repeatedly sent identical data frames have the same frame index number. When the currently received data frame is identical to the last received data frame, it indicates that the current data frame is valid. The current data frame is judged to have passed the verification, and the current data frame is stored in the cache area, overwriting the last received data frame.
[0035] In the embodiment of the present invention, the ISD interactive light controller is further used to convert the data frame that has passed the inspection into a data format that can be supported for display by the interactive light driving chip.
[0036] Furthermore, after the ISD interactive light controller determines that all data frames of the received target light pattern have passed verification, it returns a message of successful data reception to the body domain control system, and then controls the LED lights corresponding to the pixel points of the target light pattern on the light screen of the ISD interactive light according to the pattern display instructions from the infotainment system to light up, so as to display the target light pattern. The ISD interactive light controller is also used to feedback the display status of the target light pattern to the infotainment system through the body domain control system.
[0037] The data transmission process in the ISD interactive light pattern control system is described in detail below.
[0038] First, the car light pattern is generated by the infotainment system ICC, such as Figure 2 As shown, the interface jump process of the infotainment system is as follows: Click on the large screen of the infotainment system (ICC) to enter the programmable headlight interface (interface 1), and then click to enter the programmable taillight interface (interface 2). Interface 2 displays three optional light pattern forms, including static pattern, dynamic pattern and custom pattern.
[0039] When the vehicle is in driving state, the ISD interactive light can only display a static pattern, and when the vehicle is in P gear (parking state), a static pattern or a dynamic pattern can be displayed. The custom pattern described in the embodiment of the present invention is a static pattern.
[0040] If you choose a custom pattern, click the "Go to Create" module of the custom pattern option in Interface 2 to enter the custom pattern editing interface (Interface 3).
[0041] The user can edit the headlight pattern information in the left taillight / right taillight creation area of interface 3, and can also choose to synchronize the left pattern to the right / right pattern to the left, and preview the customized headlight pattern through the real-time preview module of the car model effect. After the creation is completed, the self-edited headlight pattern can be named and saved, and automatically jump to interface 2 after saving, and the customized pattern is displayed on interface 2. When the user chooses to use the customized pattern as the target headlight pattern, click the selection button under the customized pattern in interface 2 to send the data.
[0042] During the process of selecting or editing the light pattern, the in-vehicle infotainment system ICC will not send any signal to the body domain control system ZCU.
[0043] When the light pattern data is sent, the body domain control system ZCU receives the signal from the infotainment system ICC and sends it to the variable-rate CAN network (CAN with Flexible Data rate, CAN FD). The interactive light controller of the ISD interactive taillight receives the corresponding signal through the CAN FD network, sends the drive command, executes the corresponding instructions and displays the light pattern.
[0044] See also Figure 1 , Figure 3 and Figure 4 , the working process of ISD interactive light pattern control system is as follows: 1. After the target headlight pattern is selected on the large screen of the infotainment system ICC, the headlight pattern data is encapsulated into a data frame, and the signal is forwarded to the interactive light control system through the body domain control system ZCU①.
[0045] Get the target light pattern data, that is, the on / off data of the large screen pixels, and encapsulate it into four data frames, which are identified by the frame index number. Get the message ID (MSG ID) of the ISD interactive light. For example, the MSG ID of the left ISD interactive light is 0x554, and the MSG ID of the right ISD interactive light is 0x550. Send the four data frames of the target light pattern to the interactive light controller corresponding to the message ID. Specifically, send each data frame of the target light pattern three times according to a fixed sending period (CE=100ms).
[0046] The signal ① includes: 1) Data frame information ICC_RISD_FrameCounter / ICC_LISD_FrameCounter, used to mark the index number of the data frame sent to the right interactive light (RISD) or the left interactive light (LISD); 2) The transmission count information ICC_RISD_RollingCounter / ICC_LISD_RollingCounter is used to mark the index number of the transmission count of the data frame sent to the right interactive light (RISD) or the left interactive light (LISD); 3) Pixel information ICC_RISD_Pixelx / ICC_LISD_Pixelx is used to mark the LED light on / off data of the corresponding pixel on the light screen of the right interactive light (RISD) or the left interactive light (LISD).
[0047] The specific instructions are as follows: ICC_RISD_FrameCounter / ICC_LISD_FrameCounter=0x0, indicating that the first data frame is currently being sent, that is, the first data message; ICC_RISD_FrameCounter / ICC_LISD_FrameCounter=0x1, indicating that the second data frame is currently being sent, that is, the second data message; ICC_RISD_FrameCounter / ICC_LISD_FrameCounter=0x2, indicating that the third data frame is currently being sent, that is, the third data message; ICC_RISD_FrameCounter / ICC_LISD_FrameCounter=0x3, indicating that the fourth data frame, that is, the fourth data message, is currently being sent.
[0048] ICC_RISD_RollingCounter / ICC_LISD_RollingCounter=0x0, indicating the first transmission of the data frame; ICC_RISD_RollingCounter / ICC_LISD_RollingCounter=0x1, indicating the second transmission of the data frame; ICC_RISD_RollingCounter / ICC_LISD_RollingCounter=0x2, indicating the third sending of the data frame.
[0049] ICC_RISD_Pixel 1 / ICC_LISD_Pixel 1 indicates pixel 1 of the large screen; ICC_RISD_Pixel 2 / ICC_LISD_Pixel 2 indicates pixel 2 of the large screen; ICC_RISD_Pixel 3 / ICC_LISD_Pixel 3 indicates pixel 3 of the large screen.
[0050] For example, there are a total of 21×82=1722 pixels on the large screen.
[0051] Among them, ICC_RISD_Pixel x / ICC_LISD_Pixel x=0x0, indicating that pixel x corresponds to The LED light turns on; ICC_RISD_Pixel x / ICC_LISD_Pixel x=0x1, indicating that the LED corresponding to pixel x is off.
[0052] 2. The interactive light control system verifies the received data frames, saves the verified data frames into the cache area, updates the cache area data, and feeds back the data reception status to the infotainment system ICC in real time through the body domain control system ZCU.
[0053] The interactive light control system uses signal ③, i.e., RISD_TransmitStatus / LISD_TransmitStatus signal to upload the current data receiving status; RISD_TransmitStatus / LISD_TransmitStatus=0x0: Default value, indicating that it is currently in the default state; RISD_TransmitStatus / LISD_TransmitStatus=0x1: Success, indicating that data is received successfully; RISD_TransmitStatus / LISD_TransmitStatus=0x2: Fail, indicating data reception failure; RISD_TransmitStatus / LISD_TransmitStatus=0x3: Idle, indicating that the device is currently in idle state, waiting to receive data frames.
[0054] 3. After the large screen of the infotainment system ICC receives the message of successful data reception from the interactive light control system, it sends a pattern display instruction to the interactive light control system through the body domain control system ZCU.
[0055] The interactive light control system turns on / off the light pattern display switch according to signal ②: ICC_RISD_DisplaySwitch / ICC_LISD_DisplaySwitch=0x1: Display On, Indicates turning on the interactive light pattern display switch; ICC_RISD_DisplaySwitch / ICC_LISD_DisplaySwitch=0x2: Display Off, which means turning off the interactive light pattern display switch.
[0056] 4. The ISD interactive light controller feeds back the display status of the target light pattern to the infotainment system ICC through the body domain control system ZCU.
[0057] The interactive light control system feeds back the display status of the current light pattern based on signal ④, i.e., RISD_DisplayStatus / LISD_DisplayStatus signal: RISD_DisplayStatus / LISD_DisplayStatus=0x1: Not active, indicating no response at present; RISD_DisplayStatus / LISD_DisplayStatus=0x1: On, indicating that the interactive light pattern is displayed; RISD_DisplayStatus / LISD_DisplayStatus=0x1: Off, indicating that the interactive light pattern is not displayed.
[0058] Through the above steps, the data frame transmission and display of the custom headlight pattern are realized. The ISD interactive light is controlled by the interactive light control system to display the target headlight pattern, so as to intuitively convey the intention of the driver and passengers to the outside world and enhance the sense of human-computer interaction. Since the ISD interactive lights with different IDs can display different headlight patterns, the fun is improved. At the same time, the data transmission process can also ensure the stable display of the headlight pattern.

The system according to claim 5, characterized in that The determining whether the current data frame is the same as the last received data frame based on the frame index number includes: Identify the frame index number of the current data frame, and determine whether the frame index number of the current data frame is the same as the frame index number of the data frame received last time; If so, determining whether the on / off data of at least one pixel in the current data frame is the same as that in the last received data frame; If the on / off data of at least one pixel in the current data frame is the same as that in the last received data frame, it is determined that the current data frame is the same as the last received data frame.
7. The system according to claim 5 or 6, characterized in that: If the ISD interactive light controller determines that the number of received data frames is different from the number sent or determines based on the frame index number that the current data frame is different from the last received data frame, the current data frame is discarded and a message of data reception failure is returned to the infotainment system through the body domain control system. The message of data reception failure is used to instruct the infotainment system to resend the data frame of the target headlight pattern.
8. The system according to claim 1, characterized in that The ISD interactive light controller is also used to convert the data frame that has passed the inspection into a data format that the interactive light driving chip supports for display.
9. The system according to claim 1, characterized in that The ISD interactive light controller is also used to feed back the display status of the target vehicle light pattern to the infotainment system through the vehicle body domain control system.
10. A vehicle, characterized in that: The vehicle is equipped with an ISD interactive light pattern control system as described in any one of claims 1-9.
