Description

Technical Field

[0001] The present application belongs to the field of vehicle-mounted communication technology, and specifically relates to a service communication method, system and storage medium between vehicle chips. Background Art

[0002] The common way of inter-chip business communication processing in traditional vehicles is to receive business communication messages from Uart (Universal Asynchronous Receiver / Transmitter), SPI (Serial Peripheral Interface) or Ethernet through MCU or SOC, and then transmit the messages to each task module in a distributed or broadcast manner. This method of distributing or broadcasting a large amount of data will cause a large system load, low communication efficiency, and high consumption in the business communication process. At the same time, this communication method uses the protection operation of locking and unlocking public resources. When the amount of communication data is large, frequent protection operations of locking and unlocking public resources will increase the probability of deadlock, and it is easy to neglect the locking and unlocking operations of public resources, resulting in abnormal data consistency problems. Summary of the invention

[0003] In order to solve the above technical problems, the present application proposes a business communication method, system and storage medium between vehicle chips with high stability, consistency and communication efficiency.

[0004] Specifically, the present application proposes a service communication method between vehicle chips, including: S100: Obtaining business communication messages of each first business module through the first communication module, and subscribing to the business communication messages; wherein the business communication messages are communication messages that currently need to be processed, and at least include a message ID and a business processing action.

[0005] S200: Forwarding the service communication message to each second service module through the corresponding second communication module based on the message ID.

[0006] S300: Parse the service communication message through the second service module to obtain and execute corresponding service processing actions.

[0007] In the above scheme, each first business module sends a subscription request to the first communication module to subscribe to the business communication message, so that the transmission of the business communication message is allocated on demand, replacing the traditional dissemination by distribution or broadcasting, thereby improving the efficiency of inter-chip communication services and reducing the consumption of the business communication process. The transmission and management of the business communication messages by the first communication module improves the stability and consistency of business communications.

[0008] As an implementation manner, subscribing to the service communication message in step S100 may include: The first communication module receives the subscription request sent by the first service module, subscribes to the service communication message according to the subscription request, and feeds back the subscription result to the first service module after completing the subscription.

[0009] Each first service module sends a subscription request to the first communication module, and according to the subscription request, the first communication module forwards the service communication message to the corresponding first service module for operation, so that the inter-chip communication service can be allocated on demand and the efficiency of service communication is improved.

[0010] Furthermore, the step S100 may further include: The unsubscription request sent by the first service module is received through the first communication module, the subscription to the service communication message is unsubscribed, and the unsubscription result is fed back to the corresponding first service module.

[0011] When each of the first service modules no longer needs to subscribe to the service communication message, each of the first service modules sends a cancellation request to the first communication module, and the first communication module feeds back the cancellation result after receiving the cancellation request. By canceling the subscription to the service communication message, the corresponding first service module can disconnect the communication in time when no longer needing to communicate, and the system load is reduced by canceling the subscription to the service communication message.

[0012] Furthermore, the step S200 may further include: The message ID and the corresponding business processing action are packaged by the first communication module, and the business communication message obtained after the packaging is completed is transmitted to the second communication module.

[0013] The first communication module packages the message ID and the corresponding business processing action, so that after the business communication message is transmitted to the second communication module, the second communication module can pass the business communication message to the corresponding second business module for processing according to the subscription message sent by the second business module and the message ID in the business communication message. The business communication message can be forwarded to the corresponding second business module more accurately, thereby improving the accuracy of business communication.

[0014] The step of transmitting the service communication message obtained after the package assembly is completed to the second communication module includes: The service communication message sent by the first communication module is transmitted to the second communication module through the underlying communication driver module. The transmission of the service communication message through the underlying communication driver module can make the communication process not limited to the communication medium used, make the communication process more flexible, and ensure the security of the communication process.

[0015] Furthermore, the step S300 may further include: The business communication messages are verified, debugged and monitored in real time through a monitoring module to obtain and remove abnormal status messages in the business communication messages.

[0016] By monitoring the business communication messages in real time, the problem of difficulty in locating the abnormality when an abnormality occurs in the traditional communication process due to the collaboration of multiple business modules is solved. By monitoring the business communication messages in real time, the abnormality in the business communication messages can be found and located in time. By debugging the business communication messages, the business communication messages in abnormal state can be eliminated, thereby improving the security and stability of the business communication messages.

[0017] Based on the same inventive concept, the present application also proposes a system for a service communication method between vehicle chips, wherein the system includes at least a first chip and a second chip.

[0018] The first chip includes a first communication module and a plurality of first service modules; the second chip includes a second communication module and a plurality of second service modules.

[0019] The first communication module is used to receive business communication messages from each first business module and subscribe to the business communication messages; wherein the business communication messages are communication messages that currently need to be processed, and at least include a message ID and a business processing action.

[0020] The second communication module is used to forward the service communication message to each second service module based on the message ID.

[0021] The second business module is used to parse the business communication message to obtain and execute the corresponding business processing action.

[0022] Furthermore, the first chip and the second chip are also provided with a communication monitoring module; the communication monitoring module is used to verify and debug the business communication messages and monitor them in real time to obtain and remove abnormal status messages in the business communication messages. The communication monitoring module monitors and debugs the business communication messages, thereby improving the security and integrity of the business communication messages.

[0023] The first chip and the second chip are also provided with a bottom-layer communication driving module; the bottom-layer communication driving module is used to complete the transmission of service communication messages between the first communication module and the second communication module.

[0024] Based on the same inventive concept, the present application also proposes a computer-readable storage medium, which stores computer-executable instructions. When the computer-executable instructions are controlled by a control processor, the vehicle chip-to-chip service communication method is executed.

[0025] Compared with the prior art, this application has at least the following beneficial effects: The present application sends a subscription request to the communication module through the business module, and the communication module responds and distributes the received business communication message to the corresponding business module to obtain the corresponding business processing action and execute it, thereby realizing the on-demand distribution of business communication messages, improving and reducing the communication efficiency and business communication consumption of the business communication process. At the same time, it avoids frequent locking and unlocking operations on business communication messages, ensures the consistency of business communication messages, and improves the security and integrity of business communications.

[0027] Figure 2 It is a schematic diagram of a vehicle chip-to-chip service communication system shown in an embodiment of the present application. DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] Embodiment 1: Please refer to Figure 1 The vehicle chip-to-chip service communication method mainly includes steps S100 to S300.

[0030] Wherein, the step S100 mainly includes: obtaining the business communication message of each first business module through the first communication module, and subscribing to the business communication message. Wherein, the business communication message is the communication message that needs to be processed currently, and at least includes a message ID and a business processing action. The first communication module and the first business module can be components of a vehicle-mounted MCU chip, and the vehicle-mounted MCU chip is mainly responsible for controlling and processing various functions of the vehicle-mounted system, such as engine management, body control, infotainment system, etc. The vehicle-mounted MCU chip has high reliability, real-time performance and anti-interference capabilities to adapt to the complexity and requirements of the automotive environment.

[0031] When the vehicle-mounted MCU chip initiates communication, the corresponding first service module in the vehicle-mounted MCU chip will send the service communication message to the first communication module. When the vehicle-mounted MCU chip receives the service communication message, the first communication module in the vehicle-mounted MCU chip will forward the service communication message to the corresponding first service module for processing according to the message ID in the received service communication message.

[0032] When a first service module in the vehicle-mounted MCU chip needs to communicate, the first service module initiates a subscription request to the first communication module, and the first communication module subscribes to the service communication message corresponding to the subscription request. For example, assuming that the first service module is a video playback module, the video playback module sends a video signal subscription request to the first communication module, and the first communication module subscribes to the video signal. When the first communication module receives the video signal, it assigns it to the video playback module according to the message ID of the video signal.

[0033] The step S200 mainly includes: forwarding the business communication message to each second business module through the corresponding second communication module based on the message ID. The second communication module and the second business module can be components of the vehicle-mounted SOC chip, which is an integrated circuit specially designed for automobiles, combining multiple functions such as processors, memory, graphics processing units, communication interfaces, etc., to support complex vehicle-mounted systems, such as infotainment systems, advanced driver assistance systems, and vehicle networking, providing high performance, low power consumption, and high reliability. When the vehicle-mounted SOC chip receives the business communication message, the second communication module forwards the business communication message to the corresponding second business module according to the message ID in the business communication message. The message ID is a unique identifier used to distinguish different messages or data packets. It can be composed of one of numbers, letters, or a combination of both. For example, during the communication process, the message ID can be "0x1A2B3C".

[0034] The step S300 mainly includes: parsing the service communication message through the second service module to obtain and execute the corresponding service processing action. According to the communication content in the service communication message, the second service module can obtain the corresponding processing action. For example, assuming that the communication content in the service communication message is to control the vehicle system to play music, the corresponding second service module can be a music playing module, and the music playing module will control the vehicle speaker to play music after receiving the communication content.

[0035] In this embodiment, subscribing to the service communication message in step S100 includes: The subscription request sent by the first business module is received through the first communication module, the business communication message is subscribed to according to the subscription request, and the subscription result is fed back to the first business module after the subscription is completed. Among them, the subscription request may mainly include the message ID that needs to be subscribed and the corresponding processing action content. For example, when the first business module needs to process a certain business communication message, it is necessary to send the message ID and the corresponding processing action content of the business communication message to the first communication module to subscribe to this message. For example, when the reversing video playback module in the vehicle system needs to process the transmitted reversing video, it is necessary to subscribe to the video signal of the reversing video.

[0036] In this embodiment, the first communication module can receive the unsubscribe request issued by the first business module, unsubscribe the business communication message, and feed back the unsubscribe result to the corresponding first business module. When a first business module no longer needs a business communication message, it is necessary to send an unsubscribe request to unsubscribe the business communication message to reduce the system load. Among them, the unsubscribe request can also mainly include the message ID that needs to be unsubscribed and the corresponding processing action content. For example, when business communication is carried out between the on-board MCU chip and the on-board SOC chip, when a first business module in the on-board MCU chip no longer needs to communicate, the first business module sends a unsubscribe request to the first communication module, and the first communication module unsubscribes the corresponding business communication message according to the unsubscribe request, disconnecting the communication between this first business module and the first communication module.

[0037] The step S200 may also include: packaging the message ID and the corresponding message content through the first communication module, and passing the business communication message obtained after the packaging is completed to the second communication module. The business communication message sent by the first communication module is passed to the second communication module through the underlying communication driver module. For example, when the first business module needs to communicate with the second business module, the first business module needs to send the communication content and the message ID to the first communication module, the first communication module packages the communication content and the message ID, obtains the corresponding business communication message, and then passes the business communication message to the second communication module through the underlying communication driver module, and the second communication module forwards the business communication message to the second business module according to the message ID for corresponding processing.

[0038] In this embodiment, the step S300 may also include: verifying, debugging and real-time monitoring the business communication message through a monitoring module to obtain and remove abnormal status messages in the business communication message. The verification and debugging may mainly be debugging by injecting data into the business communication message and verifying the debugging result; if the debugging result is consistent with the expected result, it means that the verification and debugging is normal; if the debugging result is inconsistent with the expected result, it means that the business communication message is abnormal. The real-time monitoring may mainly include real-time monitoring of the business communication message, and accurately locating the abnormal status message when an abnormal state occurs. The abnormal status message may include data transmission error, data corruption, data format error, data conflict, protocol mismatch, and data protocol error.

[0039] For example, during the communication process between the vehicle chips, the second communication module forwards the received multiple business communication messages to the corresponding second business module for processing. When verification and debugging find that there are abnormal status messages with damaged data and incorrect data formats in the business communication messages, the location of the abnormal status messages is promptly fed back and the abnormal status messages are eliminated.

[0040] Taking the service communication between the vehicle-mounted MCU chip and the vehicle-mounted SOC chip as an example, the vehicle-mounted MCU chip is used as the sending end chip, and the vehicle-mounted SOC chip is used as the receiving end chip. Assume that the first communication module and each of the first service modules can be components of the transmitting end chip, and the second communication module and each of the second service modules can be components of the receiving end chip. The first communication module in the vehicle-mounted MCU chip obtains the message ID and service processing action that each first service module currently needs to communicate, and the first communication module packages the service processing action and the message ID to obtain the service communication message, which is transmitted to the vehicle-mounted SOC chip through the underlying communication driver module. The second communication module in the vehicle-mounted SOC chip receives the service communication message, parses the service communication message, and forwards the service communication message to the corresponding second service module for processing according to the message ID.

[0041] Those skilled in the art can adjust the service communication sequence between the vehicle-mounted chips according to actual application requirements. For example, the vehicle-mounted MCU chip is adjusted to the receiving end chip, and the vehicle-mounted SOC chip is adjusted to the sending end chip. Each second service module in the vehicle-mounted MCU chip sends a subscription request to the second communication module. The second communication module subscribes to the service communication message according to the subscription request and feeds back the subscription result to the second service module. Each first service module in the vehicle-mounted SOC chip sends a message ID and a service processing action that needs to be communicated. The first communication module packages the service processing action and the message ID to obtain the service communication message, and transmits it to the vehicle-mounted MCU chip through the underlying communication driver module. The second communication module in the MCU chip receives the service communication message, parses the service communication message, and forwards the service communication message to the corresponding second service module for processing according to the message ID and the subscription request.

[0042] Embodiment 2: Please refer to Figure 2 The present application also proposes a system for a vehicle chip-to-chip service communication method, the system comprising at least a first chip and a second chip.

[0043] The first chip mainly includes a first communication module and a plurality of first service modules, and the second chip mainly includes a second communication module and a plurality of second service modules.

[0044] The first communication module is used to receive the business communication messages of each first business module and subscribe to the business communication messages; wherein the business communication messages are the communication messages that need to be processed currently, and at least include a message ID and a business processing action. The first communication module can provide business communication message services for multiple independent first business modules at the same time. For example, when multiple first business modules need to conduct business communication, business communication messages can be sent to the first communication module at the same time, and the first communication module passes the business communication messages to the second communication module.

[0045] The second communication module is used to forward the business communication message to each second business module based on the message ID. When the second communication module receives the business communication message, it parses the business communication message to obtain the message ID, and forwards the business communication message to the corresponding second business module according to the message ID. For example, when the vehicle-mounted SOC chip receives a business communication message transmitted by other chips, the communication module in the vehicle-mounted SOC chip will parse the received business communication message to obtain the message ID, and forward the business communication message to the corresponding business processing module according to the message ID.

[0046] The second business module is used to parse the business communication message to obtain and execute the corresponding business processing action.

[0047] In this embodiment, the second chip is further provided with a communication monitoring module. The communication monitoring module is used to verify, debug and monitor the business communication messages in real time, so as to obtain and remove abnormal status messages in the business communication messages. By verifying, debugging and monitoring the business communication messages in real time through the communication monitoring module, when problems occur in the communication process, the problems can be located in time, and the abnormal status messages in the business communication messages can be removed.

[0048] For example, during the communication process, when the first communication module in the first chip sends out the business communication message, the communication monitoring module injects data into the business communication message for verification and debugging. During the verification process, if it is found that the communication protocol of a certain business communication message does not match or the business communication message is incomplete, the business communication message is treated as an abnormal status message and the verification and debugging result is fed back. The communication monitoring module removes the abnormal status message according to the verification and debugging result. When the second communication module in the second chip receives the business communication message, the communication monitoring module monitors the received business communication message in real time. When the monitoring finds that there is an abnormal status message in the business communication message, the location of the abnormal status message is fed back in time, and the communication monitoring module removes the abnormal status message according to the location.

[0049] The first chip and the second chip are also provided with a bottom-layer communication driver module. The bottom-layer communication driver module is used to complete the transmission of the business communication message between the first communication module and the second communication module. The bottom-layer communication driver module connects the first communication module in the first chip and the second communication module in the second chip. The bottom-layer communication driver module can use a communication medium to transmit the business communication message. The communication medium includes but is not limited to a bottom-layer communication driver module connected by a medium such as Uart universal asynchronous receiver / transmitter, SPI serial peripheral interface, Ethernet or CAN bus. For example, a CAN bus is used as the communication medium of the bottom-layer communication driver module for connection, and the first communication module of the first chip and the second communication module of the second chip are connected to complete the transmission of the business communication message.

[0050] The first chip and the second chip may be a vehicle-mounted MCU chip and a SOC chip, and the business communication messages issued by each business module in the MCU chip may be transmitted to the SOC chip, and each business module in the SOC chip may perform corresponding processing according to the business communication messages.

[0051] Taking the communication between the vehicle-mounted MCU chip and the SOC chip as an example, the vehicle-mounted MCU chip is used as the first chip, and the vehicle-mounted SOC chip is used as the second chip. Each first service module in the vehicle-mounted MCU chip sends a message ID and communication content to the first communication module, and the first communication module packages the service communication content and message ID into a service communication message and transmits it to the vehicle-mounted SOC chip through the underlying communication driver module. Each second service module in the vehicle-mounted SOC chip establishes communication by sending a subscription request to the second communication module, and the second communication module subscribes to the service communication message and feeds back the subscription result. The second communication module in the vehicle-mounted SOC chip forwards the service communication message to the corresponding second service module for processing according to the message ID and the subscription request. During the communication process, the service communication messages in the first communication module and the second communication module are verified, debugged and monitored in real time by the communication monitoring module to ensure the integrity and security of the service communication. Those skilled in the art can make adjustments according to actual application requirements, and can use the vehicle-mounted SOC chip as the first chip and the vehicle-mounted MCU chip as the second chip, but they are not limited to this.

[0052] Embodiment three: The present application also proposes a computer-readable storage medium, the computer-readable storage medium comprising: The computer-readable storage medium stores computer-executable instructions.

[0053] The computer executable instructions implement the vehicle chip-to-chip service communication method when executed by the control processor.

[0054] In the computer-readable storage medium, it can be implemented in whole or in part by software, hardware, firmware or any combination thereof. When implemented using software, it can be implemented in whole or in part in the form of a computer program product. The computer program product includes one or more computer instructions. When the computer program instructions are loaded and executed on a computer, the process or function described in the embodiment of the present application is generated in whole or in part. The computer may be a general-purpose computer, a special-purpose computer, a computer network, or other programmable device. The computer instructions may be stored in a computer-readable storage medium, or transmitted from one computer-readable storage medium to another computer-readable storage medium, for example, the computer instructions may be transmitted from a website site, computer, server or data center by wired (e.g., coaxial cable, optical fiber, digital subscriber line) or wireless (e.g., infrared, wireless, microwave, etc.) mode to another website site, computer, server or data center. The computer-readable storage medium may be any available medium that a computer can access or a data storage device such as a server or data center that includes one or more available media integrated. The available medium may be a magnetic medium, (e.g., a floppy disk, a hard disk, a tape), an optical medium (e.g., a DVD), or a semiconductor medium (e.g., a solid-state hard disk SolidState Disk (SSD)), etc.

[0055] In summary, the present application sends a subscription request to the communication module through the business module, and the communication module responds and distributes the received business communication message to the corresponding business module to obtain the corresponding business processing action and execute it, thereby realizing the on-demand distribution of business communication messages, improving and reducing the communication efficiency and business communication consumption of the business communication process. At the same time, it avoids frequent locking and unlocking operations on business communication messages, ensures the consistency of business communication messages, and improves the security and integrity of business communications.
