Detailed Description
The following presents a simplified summary of the disclosure in order to provide a basic understanding of the disclosure. It is not intended to identify key or critical elements of the disclosure or to delineate the scope of the protection.
For the purposes of brevity and explanation, the principles of the present disclosure are described herein primarily with reference to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to all types of data transmission methods for multiple in-vehicle devices and systems thereof, in-vehicle multi-display drive systems, computer-readable storage media, and vehicles and that these same principles may be implemented therein, and that any such variations do not depart from the true spirit and scope of the present patent application.
Also, in the following description, reference is made to the accompanying drawings that illustrate specific exemplary embodiments. Electrical, mechanical, logical, and structural changes may be made to these embodiments without departing from the spirit and scope of the present disclosure. Furthermore, while a feature of the present disclosure may have been disclosed with respect to only one of several implementations/embodiments, such feature may be combined with one or more other features of the other implementations/embodiments, as may be desired and/or advantageous for any given or identifiable function. The following description is, therefore, not to be taken in a limiting sense, and the scope of the present disclosure is defined by the appended claims and their equivalents.
Terms such as "comprising" and "including" mean that, in addition to having elements (modules) and steps that are directly and explicitly recited in the description and claims, the disclosed subject matter does not exclude other elements (modules) and steps not directly or explicitly recited.
Fig. 1 is a flow chart of a data transmission method 100 for a plurality of in-vehicle devices according to some embodiments of the present disclosure. The data transmission method 100 for a plurality of vehicle-mounted devices involves a vehicle-mounted device including a data processing end for processing data and a data implementation end for implementing the data, wherein the data processing end is an end of necessary data processing, control or driving that the vehicle-mounted device experiences before implementing the data, and the data passing through the data processing end is implemented specific to the data type at the data implementation end. For example, both displays and audio players, for example, can be substantially divided into two ends, where the data processing end is, for example, the display system at the back end of the display screen, the audio processing system at the back end of the audio player speaker, and the data implementing end is, for example, the display screen of the display, the speaker, etc.
The data transmission method 100 for a plurality of in-vehicle devices may include the steps of:
in step S1, data to be received by each of the plurality of in-vehicle devices is combined. In some examples, for example, for the same type of in-vehicle device, the same type of data (e.g., video data) may be possible, so that the data to be received by each in-vehicle device may be combined for subsequent transmission and other processing by sharing a set of transmission systems, sharing a set of processing systems, and so forth. Of course, different types of vehicle-mounted devices or data types can be combined according to the technical requirements of specific application scenes.
In step S2, the combined data is compressed using the same Serializer (SER). The combined data is transmitted to the serializer via the same transmission line and compressed in the serializer to facilitate the transmission of the data in a smaller data amount, facilitating the rapid transmission of the data.
In step S3, the compressed combined data is decompressed and split using the same Deserializer (DES), and the split data is input to the data realization terminal of the corresponding in-vehicle apparatus. After passing through the serializer, the combined and compressed data enters the deserializer for decompression and splitting, and the combined data is split in a similar manner as when the data is combined (for example, video data is spliced frame by frame when combined, and splitting is also performed frame by frame), so that the data before being combined is restored and transmitted to the data realization end of the corresponding vehicle-mounted system.
Thus, a set of transmission, compression, decompression and control schemes can be shared among a plurality of vehicle-mounted devices of the same type or different types. For example, a set of serial/deserializing link (SER/DES) may be shared, the same transmission data signal and line may be shared, and a system board may be shared to arrange hardware and modules that are all provided between other multiple in-vehicle devices such as the serial/deserializing link, and the same main control chip (e.g., main control unit MCU). Compared with the independent application of one set of hardware for each vehicle-mounted device, the space occupation of hardware arrangement in the vehicle and the cost of a plurality of hardware facilities are greatly reduced. In addition, the complexity involved in the system is reduced.
In some embodiments, multiple in-vehicle devices may use the same data processing side, with the deserializer disposed in the data processing side. For example, multiple displays may share a display system, which may be disposed on a system board (e.g., PCBA hardware system board), and further use, for example, a deserializer, a master chip, and so forth. This further increases the integration of the system and further reduces space occupation and hardware costs.
In some embodiments, the method 100 may further comprise: and transmitting the split data to a data realization end of the corresponding vehicle-mounted equipment through a functional safety module of the data processing end. In some embodiments, it may be necessary to solve the functional security problem of the data, for example, to implement detection, verification or modification of the transmitted data, and adding a functional security module may enable the transmitted data to be processed, so as to further ensure the security of the data when implemented. In particular, in some examples, a plurality of vehicle-mounted devices, for example, have a vehicle-mounted device with a high functional safety requirement, so that a functional safety module can be arranged for the vehicle-mounted device after a common system board or a common deserializer.
In some embodiments, the method 100 may further comprise: and transmitting the split data which do not pass through the functional safety module to a data realization end of the corresponding vehicle-mounted equipment through a delay module of the data processing end. For the aforementioned data transmission via the functional safety module, one or some of the on-board devices of the applicable functional safety module may be delayed relative to other on-board devices not provided with the functional safety module (e.g., delay due to functional implementation of the functional safety module itself, delay of lines and components, etc.). Thus, for data not passing through the functional safety module, the delay module of the data processing end can be passed through, which can ensure the synchronization of data input to the in-vehicle apparatus passing through the functional safety module and the in-vehicle apparatus not passing through the functional safety module to some extent, or not to cause the delay amount difference to be too large. In some examples, the role of the delay module may be played by the bridge module for signal conversion to simultaneously complete signal conversion processing such as format, protocol conversion, and the like.
In some embodiments, as previously described, the data processing side may use the same control module to control the deserializer and the data implementation side of each in-vehicle device. For example, a master control unit MCU is provided in the shared data processing end to control data transmission (e.g. whether transmission is performed or not, and the transmission rate, power, etc.). Therefore, the control modules can be shared, and the shared control modules can be arranged at the same data processing end or the same system board, so that the same control module can be utilized when a plurality of vehicle-mounted devices are subjected to fault detection and control, the control is simplified, and the differentiated control and detection of a plurality of vehicle-mounted systems are facilitated.
In some embodiments, the data implementation end of each of the plurality of in-vehicle devices is provided with a timing synchronization control module. For example, a timing control T-con chip may be provided for each display screen end (i.e., data realization end of the display) to complete timing control of data implemented by the data realization end. Further, in some examples, the data implementation end of each of the plurality of in-vehicle devices may share one timing synchronization control module. That is, components or modules may be shared on the data implementation side to further reduce space occupation and hardware costs. More importantly, the same timing synchronization control can be based on the same timing control processing program, which is more beneficial to realizing data alignment among various data realization terminals, such as alignment of video data playing among a plurality of displays.
It will be appreciated that there may be a variety of ways of combining the data, for example combining individual sub-portions of the data, the division of the sub-portions being determined by implementation effects that may refer to particular data. The data to be received by each of the plurality of in-vehicle devices includes a plurality of data units, and the step of combining the data further includes: each data unit for each of the plurality of in-vehicle devices is combined in the order of each in-vehicle device. For example, the data to be received and implemented by the in-vehicle apparatus a may be divided in accordance with the order of receptionIs a as 1 、a 2 …a n The data to be received and implemented by the vehicle-mounted device B can be divided into B according to the receiving sequence 1 、b 2 …b n A data unit, which means that the combination mode of the data is a according to the sequence of each vehicle-mounted device 1 b 1 、a 2 b 2 …a n b n . The partitioning of the data units may refer to characteristics of particular data, such as a single frame for video data, a single sonic pulse for audio data, and so forth.
Fig. 2 illustrates a block diagram of a data transmission system 200 for a plurality of in-vehicle devices, according to some embodiments. Similarly, the in-vehicle apparatus may include a data processing end for processing data and a data implementation end for implementing the data. The data transmission system 200 for a plurality of in-vehicle devices may include: a data combining means 210 for combining data to be received by each of the plurality of in-vehicle devices; a serializer 220 for compressing the combined data; a deserializer 230 for decompressing and splitting the compressed combined data and inputting the split data to a data realization terminal of the corresponding in-vehicle device; a memory 240 storing instructions; and a processor 250 configured to execute instructions to carry out the data transmission method 100 for a plurality of in-vehicle devices described according to any of the foregoing embodiments. The data combining device 210 may be, for example, a certain domain controller (e.g., SOC) of the vehicle or an audio/video signal output module/unit on the controller, which has a data combining function and a corresponding algorithm, and the data combining device 210 may be arranged in a host (e.g., vehicle computer, central control system) together with the serializer 220, for example. The description of the other modules or devices is the same or similar to that described above with respect to method 100 and is not repeated here.
Fig. 3A illustrates a block diagram of an in-vehicle multi-display drive system, according to some embodiments. The vehicle-mounted multi-display driving system includes a host, a display system, and 2 display panels (for convenience, fig. 3A shows 2 display panels (2 displays), but it is understood that other numbers of display panels are also possible). The host (e.g., an on-board computer) may include a system-on-chip SOC, for example, including the data combining means described above, for combining video data to be received by each of the display panels of the plurality of display panels described below (e.g., using an audio-video signal output module/unit on the SOC), completing the stitching and combining of data to be transmitted to the respective display panels for display, and a serializer for compressing the combined data and may, for example, provide other serializer processing operations on the data. The display system may include a deserializer for decompressing and splitting the compressed combined data, and may also perform other processing operations on the data, such as the deserializer inputting the split data to a corresponding display panel in a one-to-one correspondence. The display panels are used for displaying according to the received video data. In such a vehicle-mounted multi-display driving system, the descriptions of the modules or components may be applicable or modified as appropriate, where applicable, and the descriptions of the method 100 are the same or similar, and the descriptions are only described with respect to specific application scenarios or functions in the vehicle-mounted multi-display driving system, and the other parts are referred to the applicable descriptions above, and are not repeated herein.
In some embodiments, the display system may further include a functional security module via which the split data is transmitted to a corresponding display panel. In some embodiments, it may be necessary to solve the functional security problem of the video data, for example, to implement detection, verification or modification of the transmitted video data, and the functional security module as in fig. 3A may enable the transmitted video data to be processed, so as to further ensure the security and stability of the video data when displayed. For example, a main driving screen with high requirements for functional safety is provided in a plurality of displays, which is required to ensure real-time synchronous display of driving information and stability of display performance, so that functional safety modules can be arranged for the main driving display (screen) after a common system board or a common deserializer.
In some embodiments, the display system further includes a delay module, and the split data not passing through the functional security module is transmitted to the data implementation end of the corresponding vehicle-mounted device via the delay module of the data processing end. For the aforementioned video data transmission via the functional safety module, the main driving display, for example, of the applicable functional safety module may be delayed (e.g., due to delays in the functional implementation of the functional safety module itself, delays in the wiring and components, etc.) with respect to other displays (e.g., co-driving screen, rear-cabin screen) in which the functional safety module is not arranged. Thus, for video data that is not via the functional security module, it is possible to via the delay module of the display system as in fig. 3A, which can ensure that video display data input to the display via the functional security module and the display not via the functional security module are synchronized to some extent, or that the delay amount difference is not too large. In some examples, the role of the delay module may be played by the bridge module for signal conversion to simultaneously complete signal conversion processing such as video format, protocol conversion, and the like.
In some embodiments, each of the plurality of display panels includes a timing synchronization control module for timing synchronization of video data received by the plurality of display panels. For example, a timing control T-con chip may be provided for each display screen end (i.e., data realization end of the display) to complete timing control of data implemented by the data realization end. Further, in some examples, the data implementation end of each of the plurality of in-vehicle devices may share one timing synchronization control module. That is, components or modules may be shared on the data implementation side to further reduce space occupation and hardware costs. More importantly, the same timing synchronization control can be based on the same timing control processing program, which is more beneficial to realizing data alignment among various data realization terminals, such as alignment of video data playing among a plurality of displays.
In some embodiments, the display system may further include a main control unit for driving and controlling the plurality of display panels and the deserializer. As shown in fig. 3A, the main control unit MCU of the display system can be shared among 2 displays. As shown in fig. 3B, a block diagram of a portion of an in-vehicle multi-display drive system according to some embodiments is shown, the portion including a display panel portion and a display system portion, which is the same or similar to the description above with respect to fig. 3A. In particular, the common main control unit MCU shown in fig. 3B can realize control of the timing synchronization control modules (chips) arranged in the respective display panels and control of the deserializer split data, and control the transmission rate, transmission power, and the like of video data to control the display effect. The main control unit MCU may also enable control of the two modules, for example in a display system in which the functional safety module or the delay module is arranged, such as enabling and disabling of the respective functions of the functional safety module, enabling and disabling of the delay module, and adjustment of the delay amount, etc. In addition, the same main control unit is used for controlling the time sequence control of the deserializer and the display panels, the main control unit is connected with the gateway of the whole vehicle, the switch, the brightness and the like of 2 display panels can be respectively controlled, and when a certain display panel fails, the single main control unit MCU can also uniformly identify, detect and report and carry out subsequent processing logic.
In some embodiments, the video data to be received by each of the plurality of display panels may include a plurality of frames, and the SOC is further configured to combine the video data by combining the individual frames for each of the plurality of display panels in the order of each display panel. In some examples, the SOC utilizes its audio/video signal output module/unit to perform the sequential combination of frames described above. For example, video data to be received and implemented by display A may be divided into a according to the order of reception 1 、a 2 …a n The video data to be received and implemented by display B can be divided into frames B according to the receiving order 1 、b 2 …b n Each frame, in order of each in-vehicle device, means that the data is combined in a way of a 1 b 1 、a 2 b 2 …a n b n 。
Further, in some embodiments, each of the plurality of display panelsThe video data to be received respectively includes a plurality of frames including a plurality of rows of pixel data, and the SOC is further configured to combine the video data by combining each row of pixel data for each frame of each of the plurality of display panels in order of each display panel. That is, for example, video data to be received and implemented by the display a may be divided into a according to the receiving order 1 、a 2 …a n A number of frames, each divided into a number of rows (scan lines, e.g. pixel scan lines based on RGB pixel coding), e.g. a 1 h 1 、a 1 h 2 、a 1 h 3 、…a 1 h m ；a 2 h 1 、a 2 h 2 、a 2 h 3 、…a 2 h m ；a 3 h 1 、a 3 h 2 、a 3 h 3 、…a 3 h m ；……a n h 1 、a n h 2 、a n h 3 、…a n h m . While the video data to be received and implemented by display B may be divided into B according to the order of reception 1 、b 2 …b n A plurality of frames, each frame divided into a plurality of rows (scan lines, e.g., pixel scan lines based on RGB pixel coding), e.g., b 1 h 1 、b 1 h 2 、b 1 h 3 、…b 1 h m ；b 2 h 1 、b 2 h 2 、b 2 h 3 、…b 2 h m ；b 3 h 1 、b 3 h 2 、b 3 h 3 、…b 1 h m ；……b n h 1 、b n h 2 、b n h 3 、…b n h m . In order of each vehicle-mounted device, means that the data is combined in a way of a 1 h 1 b 1 h 1 、a 1 h 2 b 1 h 2 、a 1 h 3 b 1 h 3 …a 1 h m b 1 h m 、a 2 h 1 b 2 h 1 、a 2 h 2 b 2 h 2 、a 2 h 3 b 2 h 3 …a 2 h m b 2 h m 、a 3 h 1 b 3 h 1 、a 3 h 2 b 3 h 2 、a 3 h 3 b 3 h 3 …a 3 h m b 3 h m ...a n h 1 b n h 1 、a n h 2 b n h 2 、a n h 3 b n h 3 …a n h m b n h m . It may be understood, for example, that after display a displays a row of a frame, display B displays a row of a frame, then display a displays a next row of the frame, and then display B displays a corresponding next row of a corresponding frame. In this way, further increases in the degree of timing synchronization of video data between displays can be facilitated by combining, splitting and distributing data for multiple display times per frame, each scan line by scan line.
For example, the pixel points are exemplified by digital signals, each pixel has, for example, 1 to 10 or more bits (hereinafter, 1 bit per pixel is exemplified) and each row has, for example, 10 pixels, and then each row of pixels can be represented as a digital signal like 1011010110. Further, for more complex pixel points, more pixel colors (e.g., RGB three colors) may be represented every 8 bits. Wherein 0/1 bit of the digital signal may characterize the high and low level (e.g., high level 5V) of the analog signal.

The electronic device comprises a memory and a processor, the memory storing instructions that, when executed by the processor, carry out the method 100 according to any one of the preceding embodiments.
According to another aspect of the present disclosure, there is also provided a computer-readable storage medium storing instructions that, when executed, perform the method 100 according to any of the embodiments of the present disclosure.
