Obviously, the described embodiments are 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.
[0046] Reference Figure 1 , shows a flowchart of the steps of a remote diagnosis method of a vehicle MCU state provided by an embodiment of the present application. Figure 1 As shown, the remote diagnosis method of the vehicle MCU status may include: step 101, step 102 and step 103.
[0047] Step 101: calling a fault diagnosis monitoring module pre-installed in the MCU to monitor the fault diagnosis information and operation status information of MCU modules in the MCU except the fault diagnosis monitoring module.
[0048] The embodiments of the present application can be applied to scenarios where communication between an SOC and an MCU is used to implement remote fault diagnosis and debugging of the MCU.
[0049] In this embodiment, a fault diagnosis monitoring module may be pre-installed in the vehicle MCU, and the fault diagnosis monitoring module may monitor the fault information of other modules in the MCU in real time and perform preliminary diagnosis on the fault information of other modules.
[0050] In a specific implementation, each functional module on the MCU side (i.e., the MCU module in this example) can collect possible fault information of itself and the operation status information associated with the fault information troubleshooting in real time, and output the fault information and operation status information to the fault diagnosis and monitoring module.
[0051] At this time, the fault diagnosis monitoring module can be called to obtain the fault information and operation status information output by each MCU module. At the same time, the fault diagnosis monitoring module can perform preliminary diagnosis on the fault information to obtain fault diagnosis information. The implementation process can be described in detail in combination with the following specific implementation method.
[0052] In a specific implementation of the present application, the above step 101 may include:
[0053] Sub-step A1: calling the fault diagnosis monitoring module to monitor and obtain the fault information and operation status information of the MCU module.
[0054] In this embodiment, the fault diagnosis monitoring module may be called first to monitor and obtain the fault information and operation status information of the MCU module.
[0055] After the fault diagnosis monitoring module is called to monitor and obtain the fault information and operation status information of the MCU module, sub-step A2 is executed.
[0056] Sub-step A2: Perform a preliminary diagnosis on the fault information to obtain fault diagnosis information of the MCU module.
[0057] After calling the fault diagnosis monitoring module to monitor and obtain the fault information and operating status information of the MCU module, the fault diagnosis monitoring module can be called to perform preliminary diagnosis on the fault information to obtain the fault diagnosis information of the MCU module. In the specific implementation, the fault diagnosis monitoring module can collect the operating status information and fault information output by each MCU module on the MCU side, and monitor in real time. For the content that the module itself cannot diagnose, the fault diagnosis module monitors and diagnoses through the operating status information to obtain the fault diagnosis information.
[0058] The embodiment of the present application can monitor the fault information and operating status information of other functional modules in the MCU in real time by pre-installing a fault diagnosis monitoring module in the MCU, and output it to the SOC to achieve remote diagnosis and debugging, thereby providing a basis for remote diagnosis and debugging of the MCU.
[0059] After calling the fault diagnosis monitoring module pre-installed in the MCU to monitor the fault diagnosis information and operation status information of the MCU modules other than the fault diagnosis monitoring module in the MCU, step 102 is executed.
[0060] Step 102: Send the fault diagnosis information and the operating status information to the SOC.
[0061] After the fault diagnosis information and operating status information of the MCU modules other than the fault diagnosis monitoring module in the MCU are obtained through monitoring, the fault diagnosis information and operating status information may be sent to the SOC.
[0062] In a specific implementation, an inter-chip communication module is provided in the MCU. After obtaining the fault diagnosis information and the operating status information, the fault diagnosis monitoring module can send the fault diagnosis information and the operating status information to the inter-chip communication module in the MCU. Furthermore, the inter-chip communication module in the MCU can send the fault diagnosis information and the operating status information to the inter-chip communication module in the SOC based on the inter-chip communication protocol.
[0063] Among them, chip-to-chip communication protocols refer to protocols for data transmission and communication between different chips. These protocols define how to exchange information between chips, including the format, transmission method, synchronization mechanism, etc. of data, to ensure that data can be accurately and reliably transmitted between chips. In this example, the chip-to-chip communication protocol can be, but is not limited to: I2C protocol, UART protocol, SPI protocol, etc.
[0064] After the fault diagnosis information and the operation status information are sent to the SOC, step 103 is executed.
[0065] Step 103: Call the SOC to generate and store the fault log information of the MCU module according to the fault diagnosis information and the operating status information, and display the fault diagnosis information and the operating status information in a preset interface, so that the remote server can perform fault diagnosis and debugging on the MCU module according to the fault diagnosis information and the operating status information when remotely logging into the SOC.
[0066] After the fault diagnosis information and the operating status information are sent to the SOC, the SOC can be called to generate the fault log information of each MCU module in the MCU according to the fault diagnosis information and the operating status information, and the fault diagnosis information and the operating status information are displayed in the preset interface. Specifically, the SOC can be connected to the PC in the vehicle, so that the fault diagnosis information and the operating status information can be displayed on the visual interface of the PC, which is the preset interface.
[0067] Among them, the fault log information can be archived for fault location.
[0068] When the remote server needs to perform fault diagnosis and debugging on the vehicle MCU, the remote server can remotely log in to the SOC and perform fault diagnosis and debugging on the MCU module based on the fault diagnosis information and operating status information.
[0069] The embodiment of the present application installs a fault diagnosis monitoring module in the MCU to monitor the fault information of other modules in the MCU in real time and perform preliminary diagnosis. At the same time, based on the inter-chip communication between the MCU and the SOC, the fault diagnosis information on the MCU is forwarded to the SOC. Through log storage and visualization interface tools, real-time online analysis of simple fault problems on the MCU side and historical log archiving and rapid analysis of complex fault problems are achieved, thereby improving the efficiency of fault analysis. In addition, remote debugging of the MCU side can be achieved, reducing the dependence on debuggers and other equipment and local scenarios, improving the debugging efficiency of the MCU, and saving time and effort.
[0070] In this embodiment, after the MCU and the SOC complete the interaction of fault information, the remote server can remotely log in to the SOC and perform remote debugging in combination with the fault diagnosis information and operation status information displayed by the SOC. This implementation process can be described in detail in combination with the following specific implementation methods.
[0071] In a specific implementation of the present application, after the above step 103, the following may also be included:
[0072] Step B1: calling the SOC to obtain the fault debugging information for the MCU module sent by the remote server.
[0073] In this embodiment, when the MCU needs to be remotely debugged, the remote server can remotely log in to the SOC, and perform fault diagnosis on each MCU module according to the fault diagnosis information and operation status information of each MCU module in the MCU recorded and displayed in the SOC. At the same time, fault debugging information of each MCU module can be generated according to the fault diagnosis result, and the fault debugging information is sent to the SOC.
[0074] Furthermore, the SOC can be called to obtain the fault debugging information for the MCU module sent by the remote server.
[0075] After calling the SOC to obtain the fault debugging information for the MCU module sent by the remote server, step B2 is executed.
[0076] Step B2: calling the inter-chip communication module in the SOC to send the fault debugging information to the MCU.
[0077] After calling SOC to obtain the fault debugging information for the MCU module sent by the remote server, the inter-chip communication module in SOC can be called to send the fault debugging information to MCU. Specifically, the inter-chip communication module of SOC can be called to send the fault debugging information to the inter-chip communication module in MCU.
[0078] After the inter-chip communication module in the SOC is called to send the fault debugging information to the MCU, step B3 is executed.
[0079] Step B3: calling the MCU to perform fault debugging on the faulty MCU module according to the fault debugging information.
[0080] After calling the inter-chip communication module in the SOC to send the fault debugging information to the MCU, the MCU can be called to debug the faulty MCU module according to the fault debugging information. Specifically, the memory processing module in the MCU can be called to read the debugging variable parameters in the debugging information. The debugging variable parameters are written into the corresponding MCU module to perform the corresponding debugging operation to complete the fault debugging.
[0081] The embodiment of the present application realizes remote debugging of the MCU side through debugging information interaction between the MCU and the SOC based on a customized debugging protocol, reduces dependence on devices such as debuggers and local scenarios, improves energy efficiency, and saves time and effort.
[0082] Next, combine Figure 2 The process of remote fault diagnosis and debugging of MCU is described in detail.
[0083] Reference Figure 2 , shows a schematic diagram of a remote diagnosis and debugging process of an MCU in a smart driving domain control system provided by an embodiment of the present application. Figure 2 As shown, the MCU-side remote diagnosis and debugging process may include:
[0084] 1. Output of status information of each module on the MCU side. That is, each functional module on the MCU side sorts out the possible fault information of the module itself and the status information associated with the fault information troubleshooting, and outputs them uniformly to provide a basis for troubleshooting for remote diagnosis.
[0085] 2. The fault diagnosis monitoring module collects the status of each module and performs monitoring and diagnosis processing. That is, the fault diagnosis monitoring module collects the output status information and fault information of each module on the MCU side, and monitors in real time. For the content that the module itself cannot diagnose, the fault diagnosis module monitors and diagnoses through the module status information.
[0086] 3. Inter-chip communication information processing module on the MCU side. The inter-chip communication information processing module on the MCU side forwards the status information and fault diagnosis information of each module to the SOC side through inter-chip communication.
[0087] 4. SOC-side inter-chip communication information processing module. The SOC-side inter-chip communication information processing module receives the status information and fault diagnosis information of each module on the MCU side through inter-chip communication. On the one hand, it uploads it to the visualization tool for visualization processing, and on the other hand, it records the diagnostic log information and archives the historical information.
[0088] 5. Real-time recording of diagnostic log information. SOC stores the received MCU-side diagnostic and status information in real-time logs, saves evidence and clues, and facilitates the location and analysis of complex problems.
[0089] 6. Visual tool diagnostic information display. The SOC uploads the received MCU-side diagnostic and status information to the visualization tool, which can display the MCU-side fault status information in real time, making it easy to quickly locate simple problems.
[0090] 7. Debug information input and output. The SOC inputs corresponding instructions through debug information, such as reading and writing variable information, and transmits the corresponding debug interaction information to the MCU through the inter-chip communication information processing module of the SOC. Among them, debug information debugging is very flexible on the SOC side. You can develop and deploy a script tool with a window, and input the variable address information of the MCU side that needs to be read or written through the window. Debug interaction information refers to the interaction between the MCU and the SOC through inter-chip communication, which can be through the Spi serial port or Ethernet communication. In simple terms, it is the data interaction between the MCU and the SOC side through inter-chip communication. Debug interaction information includes the instruction information related to the variable sent by the SOC to the MCU. For example, when reading the variable value, the debug interaction information refers to: the variable address information and length information sent by the SOC to the MCU, and the variable value information replied by the MCU to the SOC. For example, when writing the variable value, the debug interaction information refers to: the variable address information, length information and variable value information to be written sent by the SOC to the MCU, and the write result replied by the MCU to the SOC.
[0091] 8. Memory processing module: After receiving the debugging interaction information, the MCU-side inter-chip communication information processing module interacts with the memory processing module to read or write the corresponding variable value.
[0092] 9. Trigger Action. When the corresponding variable value on the MCU side is modified, the predefined Action is triggered to perform the corresponding response operation. These predefined Actions can be customized according to needs. After the SOC side sends the debugging interaction information of the inter-chip communication to the MCU, the Action can be, for example, writing the corresponding variable value operation. The MCU side will perform corresponding processing operations according to the changes in the local variable value, such as executing a function, controlling a peripheral register, etc.
[0093] In the current situation of debugging and diagnosis based on the MCU, in order to reduce the dependence of MCU diagnosis and debugging on local and debugging equipment, and to improve the real-time and energy efficiency of fault diagnosis, the embodiments of the present application can only indirectly realize this remote connection mode with the help of the SOC end, realize remote diagnosis and debugging, and improve the efficiency of fault diagnosis and functional debugging on the MCU end. Based on the inter-chip communication between the MCU and the SOC end, the fault diagnosis information on the MCU end is forwarded to the SOC, and through the log storage and visualization interface tools, the real-time online analysis of simple fault problems on the MCU end and the historical log archiving and rapid analysis of complex fault problems are realized, which improves the efficiency of fault analysis.
[0094] The remote diagnosis method of the vehicle MCU state provided in the embodiment of the present application monitors the fault diagnosis information and operating status information of the MCU modules other than the fault diagnosis monitoring module in the MCU by calling the fault diagnosis monitoring module pre-installed in the MCU. The fault diagnosis information and operating status information are sent to the SOC. The SOC is called to generate and store the fault log information of the MCU module according to the fault diagnosis information and operating status information, and the fault diagnosis information and operating status information are displayed in the preset interface. The remote server performs fault diagnosis and debugging on the MCU module according to the fault diagnosis information and operating status information when logging into the SOC remotely. The embodiment of the present application installs the fault diagnosis monitoring module in the MCU to monitor the fault information of other modules in the MCU in real time and perform preliminary diagnosis. At the same time, based on the inter-chip communication between the MCU and the SOC end, the fault diagnosis information on the MCU end is forwarded to the SOC, and the real-time online analysis of simple fault problems on the MCU end and the historical log archiving and rapid analysis of complex fault problems are realized through log storage and visualization interface tools, thereby improving the efficiency of fault analysis.
