[0023] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0024] A method and device for determining the operating state of a processor according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0025] Figure 1 A method for determining the operating state of a processor provided in an embodiment of the present application is as follows: Figure 1 As shown, the method includes:

[0026] S101, determining an instance task corresponding to a processor in a vehicle, and generating a corresponding configuration file according to the instance task;

[0027] S102, generating a monitoring application corresponding to the processor and the instance task according to the configuration file;

[0028] S103: Receive kernel information and task execution information returned by the monitoring application, and determine the running state of the processor according to the kernel information and the task execution information.

[0029] It can be understood that the above-mentioned vehicles include vehicles with automatic driving or intelligent driving (including vehicles with passenger functions (such as cars, buses, large buses, minibuses, etc.), vehicles with cargo functions (such as ordinary trucks, vans, trailers, closed trucks, tank trucks, flatbed trucks, container trucks, dump trucks, trucks with special structures), special vehicles (such as logistics distribution vehicles, automatic guided transport vehicles AGV, patrol cars, cranes, cranes, excavators, bulldozers, forklifts, rollers, loaders, off-road engineering vehicles, armored engineering vehicles, sewage treatment vehicles, sanitation vehicles, vacuum trucks, floor washing vehicles, sprinkler trucks, sweeping robots, food delivery robots, shopping guide robots, lawn mowers, golf carts, etc.), vehicles with entertainment functions (such as entertainment vehicles, amusement park automatic driving devices, balance cars, etc.), rescue vehicles (such as fire trucks, ambulances, power repair vehicles, engineering rescue vehicles, etc.)), etc. The method for determining the operating status of the above-mentioned processor provided in this example is applied to at least one of a vehicle, a server, and a terminal. For better explanation, the following description will take the application of the method for determining the operating status of the processor provided in this example to the terminal as an example.

[0030] It can be understood that the vehicle operating system adopts the Classic AutoSAR Platform (CP) standard, and the software in the vehicle adopts the AUTOSAR software architecture. In the AUTOSAR software architecture, it is divided into three layers, as follows: Application layer (SWC), interface layer (RTE), and basic software layer (BSW). Among them, SWC is used to define the functions of the software, mainly using the model development method, focusing on logic; RTE is used to provide the communication interface between SWC and BSW; BSW has a module dedicated to system log information collection, DLT (Diagnostic Log and Trace) module, which collects system log messages (logmessage), and then converts them into a standard data format for transmission to PDUR (Protocol Data Units Router) for message routing and forwarding, and forwarding to the corresponding message bus (communication bus) for transmission. The information that needs to be transmitted is defined by AUTOSAR, and users cannot customize log messages according to actual application scenarios, making it impossible to obtain kernel information and task execution information when the processor executes instance tasks.

[0031] In some examples, an instance task corresponding to a processor in a vehicle is determined. It can be understood that in a vehicle, a processor of a vehicle controller usually runs multiple tasks, each task is responsible for performing a specific function or processing specific data. An instance task refers to a specific instance of these tasks, that is, a specific execution entity of a task.

[0032] Following the above example, after determining the example task, this example further generates a corresponding configuration file according to the example task. The configuration file is usually generated and stored in a preset format (e.g., text format), so that relevant personnel can edit and view the configuration file through an editor corresponding to the preset format. The above configuration file includes information such as the kernel required by the processor to execute the above example task, the scheduling time of the task, etc.

[0033] In some examples, after obtaining the configuration file, this example further generates a monitoring application corresponding to the processor and the instance task according to the configuration file, wherein the monitoring application is used to monitor the kernel information of the processor and the task execution information corresponding to the instance task; specifically, this example develops a corresponding monitoring application according to the kernel, task scheduling time and other information in the configuration file, and the above monitoring application is used to monitor the kernel information of the processor (such as CPU usage, memory usage, etc.) and the execution information of the instance task (such as task execution time, task status, etc.) according to the configuration information. It can be understood that the monitoring application can obtain real-time kernel information and then task execution information by polling the processor and task status.

[0034] It can be understood that the monitoring application can be executed by the processor of the vehicle controller, that is, the storage format of the monitoring application corresponds to the format that the processor can run; for example, the program executed by the processor of the vehicle controller is an application under the AUTOSAR software architecture, such as Figure 2 As shown, first, the corresponding configuration file is configured according to the instance task executed by the processor, and then the configuration file is processed by the configuration tool to generate ".c" and ".h" files. Then, through the AUTOSAR configuration tool, the generated files need to be included to generate a monitoring application and compile it to finally generate an executable hex file. Finally, the executable hex file is burned into the corresponding processor through the burning tool to run, so that the processor executes the above monitoring application.

[0035] It can be understood that a monitoring application is generated through the above method and burned into the processor for execution, so that the processor can execute the above monitoring application, and the monitoring application can accurately obtain the kernel information and task execution information when the processor executes the instance task, avoiding the problem that the processor (MCU) lacks a monitoring method to observe the health status of the processor operation, and cannot confirm the actual operation status of the tasks running on the processor, which leads to the inability to locate the anomaly when the processor executes business functions and logic abnormalities, affecting the efficiency of software development.

[0036] In some examples, kernel information and task execution information returned by a monitoring application are received, and the operating status of the processor is determined based on the kernel information and task execution information, thereby enabling monitoring of the kernel information and execution information of the processor in the vehicle controller when executing an instance task. During the software development process, when an exception occurs when the processor executes an instance task, the exception can be discovered in a timely manner and the cause of the exception can be located, thereby improving software development efficiency. During vehicle use, when an exception occurs when the processor executes an instance task, the exception can be discovered in a timely manner, the cause of the exception can be located, and the above exception can be repaired, thereby improving the stability and reliability of the vehicle system.

[0037] According to the technical solution provided in the embodiment of the present application, the above method determines the instance task corresponding to the processor in the vehicle, and generates a corresponding configuration file according to the instance task; generates a monitoring application corresponding to the processor and the instance task according to the configuration file, and the monitoring application is used to monitor the kernel information of the processor and the task execution information corresponding to the instance task; receives the kernel information and task execution information returned by the monitoring application, and determines the running state of the processor according to the kernel information and the task execution information, and realizes the monitoring of the kernel information and execution information of the processor in the vehicle controller when executing the instance task through the monitoring application, so that in the process of software development, when the processor executes the instance task abnormally, the abnormality can be discovered in time and the cause of the abnormality can be located, thereby improving the software development efficiency; when the processor executes the instance task abnormally during vehicle use, the abnormality can be discovered in time and the cause of the abnormality can be located, and the above abnormality can be repaired, thereby improving the stability and reliability of the vehicle system, and avoiding the problem that the processor in the vehicle cannot locate the abnormality when executing business functions and logic abnormally, thereby affecting the software development efficiency.

[0038] In some embodiments, the configuration file includes: a processor configuration file and a task configuration file, such as Figure 3 As shown, the corresponding configuration file is generated according to the instance task, including:

[0039] S301, determining the task identifier, task quantity and task scheduling time corresponding to the instance task, and generating a task configuration file according to the task identifier, task quantity and task scheduling time;

[0040] S302: Determine a processor identifier and a core usage rate corresponding to the instance task, and generate a processor configuration file according to the processor identifier and the core usage rate.

[0041] Specifically, when the monitoring application is monitoring the core information of the processor and the task execution information corresponding to the instance task, it is necessary to clearly define the monitoring object in order to accurately obtain the core information and task execution information.

[0042] Continuing with the above example, when the processor is executing an instance task, the task identifier, task quantity and task scheduling time corresponding to the instance task should have a certain regularity. If the above task identifier, task quantity and task scheduling time are abnormal, it can be determined that the processor has executed the instance task abnormally. Therefore, this example determines the above task configuration file based on the task identifier, task quantity and task scheduling time, and then provides the necessary monitoring information for the monitoring application.

[0043] Similarly, when the processor is executing an instance task, the processor performance and load conditions should have certain regularities. The core usage rate is used to characterize the processor performance and load conditions. If the core usage rate is abnormal, it indicates that the processor is abnormal in executing the instance task. Therefore, this example generates a processor profile based on the processor identification and core usage rate.

[0044] It is understandable that relevant technical personnel can define the important information of the processor and the important information of the task to be executed according to actual needs, such as Figure 4 As shown, Figure 4 Cpu_i nfo is an example of a processor configuration file provided in this embodiment, which includes "+name: string (get content); + Core I d: int (processor identifier); + CpuLoad: int (core usage rate)". It can be understood that, if Figure 4 As shown, the processor profile needs to rely on the standard interface of the CP's OS (operating system); Figure 4 Task_i nfo is an example of a task configuration file provided in this example, which includes "+name: string (get content); + Runtime: int (task scheduling time); + StackUsage: int (stack usage); + Task ID: int (task ID)". It can be understood that, for example Figure 4 As shown, the kernel configuration file needs to rely on the interface corresponding to the instance task.

[0045] According to the technical solution provided in the embodiment of the present application, the task identifier, task quantity and task scheduling time corresponding to the instance task are determined, and a task configuration file is generated based on the task identifier, task quantity and task scheduling time; the processor identifier and core usage rate corresponding to the instance task are determined, and a processor configuration file is generated based on the processor identifier and core usage rate, wherein the specific monitoring objects are clarified through the above-mentioned processor configuration file and task configuration file, so that the monitoring application can accurately obtain the above-mentioned kernel information and task execution information according to the processor configuration file and task configuration.

[0046] In some embodiments, Figure 5 As shown, a monitoring application corresponding to the processor and instance task is generated according to the configuration file, including:

[0047] S501, determining a monitoring object according to a task configuration file and a processor configuration file, and determining a monitoring period according to an instance task;

[0048] S502: Construct a monitoring application according to the monitoring cycle and the monitoring object.

[0049] Specifically, this example determines the objects to be monitored through the task configuration file and the processor configuration file, that is, the above-mentioned task identification, task quantity, task scheduling time, core usage rate and other information.

[0050] In some examples, determining the monitoring period based on the instance task includes: obtaining the importance of the instance task, and determining the corresponding monitoring period based on the degree of importance of the instance task; specifically, if the degree of importance of the instance task is high, determining the monitoring period to be the first monitoring period; if the importance of the instance task is low, determining the monitoring period to be the second monitoring period, wherein the duration of the first monitoring period is shorter than the duration of the second monitoring period; for example, the first monitoring period is 1 second, and the second monitoring period is 3S.

[0051] After determining the monitoring cycle and the monitoring object, this example further constructs a monitoring application according to the monitoring cycle and the monitoring object, so that the monitoring application obtains the information of the monitoring object according to the above monitoring cycle. For example, taking the monitoring cycle as 1 second, the monitoring application obtains the information of the monitoring object every 1 second.

[0052] In order to better understand the above steps, this embodiment provides a more specific example for illustration. Figure 4 As shown, after determining the task profile and the processor profile, this example further provides the interfaces of the task profile and the processor profile to the basic software layer (Basic Software, BSW) module for integration, and sets a fixed monitoring cycle to obtain the monitoring application Vdms_swc, thereby achieving the acquisition of CPU information and task information (task identification, number of tasks, task scheduling time, core utilization) through a fixed monitoring cycle.

[0053] According to the technical solution provided in the embodiment of the present application, the monitoring object is determined according to the task configuration file and the processor configuration file, and the monitoring period is determined according to the instance task; a monitoring application is constructed according to the monitoring period and the monitoring object, so that the monitoring application can obtain the information of the monitoring object according to the monitoring period.

[0054] In some embodiments, Figure 6 As shown, before receiving the kernel information and task execution information returned by the monitoring application, the method also includes:

[0055] S601, determining an information acquisition interface and a communication link interface;

[0056] S602: Generate a target file according to the information acquisition interface, the communication link interface and the monitoring application, and write the target file into the processor so that the processor runs the monitoring application.

[0057] Specifically, this example determines an information acquisition interface and a communication link interface through a basic software module (bsw_module), wherein the information acquisition interface is used for the monitoring application to obtain kernel information and task execution information, and the communication link interface is used for the monitoring application to perform data transmission, and the above-mentioned communication link interface transmits messages through a controller area network bus (Controller Area Network, CAN) or an in-vehicle Ethernet (Ethernet, ETH); specifically, taking the kernel information and task execution information including task identification, task quantity, task scheduling time and kernel utilization rate as an example, the above-mentioned monitoring application obtains the task identification, task quantity, task scheduling time and kernel utilization rate through the information acquisition interface, and then sends the obtained task identification, task quantity, task scheduling time and kernel utilization rate through the above-mentioned communication link interface to the vehicle gateway, and the vehicle gateway further sends the above-mentioned task identification, task quantity, task scheduling time and kernel utilization rate and other data to the terminal, so that the terminal can receive the above-mentioned task identification, task quantity, task scheduling time and kernel utilization rate and other information.

[0058] In some examples, a target file is generated according to the information acquisition interface, the communication link interface, and the monitoring application, and the target file is written into the processor so that the processor runs the monitoring application, specifically, Figure 4 As shown, through the AUTOSAR configuration tool, the information acquisition interface and communication link interface files provided by the above monitoring application and the basic software module (bsw_module) are included, the monitoring application is generated, and compiled, and finally an executable target file (hex file) is generated. Finally, the executable hex file is burned into the corresponding processor through the burning tool, so that the processor executes the above monitoring application.

[0059] It can be understood that the above-mentioned monitoring application calls the information acquisition interface (for example: GetCpuLoad) provided by (bsw_module) during its scheduling cycle to obtain kernel information and execution task information, and synchronizes it to the storage area (the storage area can be defined by relevant technical personnel) to cache the data, and after the synchronization is completed, use the communication link interface (CAN / ETH) provided by (bsw_module) to send data.

[0060] It is understandable that if Figure 7 As shown, Figure 7Shown is a basic schematic diagram of the CP software architecture, which includes functional modules such as environment and support (Runtime Environment, RTE), services layer (Services Layer) and complex device module (Complete Drivers, CDD). Among them, this example also provides a vehicle diagnostics and monitoring system (VDMS). The VDMS module is integrated in the CDD module, and the monitoring application directly calls the interface of the vdms module. At the same time, the vdms module needs to use the OS (module in the Servers Layer) interface and communication-related interfaces.

[0061] According to the technical solution provided in the embodiment of the present application, an information acquisition interface and a communication link interface are determined; a target file is generated based on the information acquisition interface, the communication link interface and the monitoring application, and the target file is written into the processor, so that the processor runs the monitoring application, so that the monitoring application can obtain the processor's kernel information and the task execution information corresponding to the instance task through the information acquisition interface, and send the processor's kernel information and the task execution information corresponding to the instance task through the communication link interface.

[0062] In some embodiments, Figure 8 As shown, before determining the running state of the processor according to the kernel information and the task execution information, the method further includes:

[0063] S801, determining a corresponding message content format according to the kernel information and the task execution information, and determining a corresponding message header format according to the information acquisition interface and the communication link interface;

[0064] S802. Define the data structure of the data transmitted by the monitoring application according to the message content format and the message header format.

[0065] Specifically, in order to ensure that the kernel information and task execution information sent by the monitoring application can be correctly received and parsed, this example needs to further define the data structure of the data transmitted by the monitoring application, so that the above kernel information and task execution information can be obtained based on the subsequent data parsing transmitted by the monitoring application.

[0066] In some examples, the corresponding message content format is determined based on the kernel information and the task execution information, wherein the message content format is determined by determining the degree of matching between the kernel information and the task execution information and the content forms such as structure, JSON, and XML; exemplarily, if the XML format can clearly and completely express the above-mentioned kernel information and task execution information, and the data volume of the kernel information and the task execution information in the XML format is small, then it is determined that the degree of matching between the XML format and the kernel information and the task execution information is high; if the JSON format can clearly and completely express the above-mentioned kernel information and task execution information, but the data volume of the kernel information and the task execution information in the JSON format is large, then it is determined that the degree of matching between the JSON format and the kernel information and the task execution information is average.

[0067] In some examples, the corresponding packet header format is determined according to the information acquisition interface and the communication link interface, and the packet header format includes information such as an identifier, a counter, a length, a timestamp, and data content. It can be understood that the packet header format may vary with the transmission protocol supported by the information acquisition interface and the communication link interface.

[0068] It is understandable that after obtaining the kernel information and the task execution information, the monitoring application can put the kernel information and the task execution information in one piece of data, or can put the kernel information and the task execution information in different pieces of data; for example, Fig. 9 As shown, Fig. 9 It is defined in the data packet header of the monitoring application that includes an identifier (ID), a counter (CNT), a length (LEN), and a timestamp (Len), and a piece of data also includes kernel information (CPUData) and task execution information (Task Data).

[0069] According to the technical solution provided in the embodiment of the present application, the corresponding message content format is determined according to the kernel information and the task execution information, and the corresponding message header format is determined according to the information acquisition interface and the communication link interface; the data structure of the monitoring application transmission data is defined according to the message content format and the message header format, thereby ensuring that the kernel information and task execution information sent by the monitoring application can be correctly received and parsed.

[0070] In some examples, such as Fig.10 As shown, the operating state of the processor is determined according to the kernel information and the task execution information, including:

[0071] S1001, comparing the kernel information with the preset target kernel information to obtain a first comparison result; comparing the task execution information with the preset target task execution information to obtain a second comparison result;

[0072] S1002: If the first comparison result indicates that the kernel is running abnormally or the second comparison result indicates that the task is executed abnormally, determine that the running state of the processor is abnormal.

[0073] Specifically, when the processor is executing an instance task, the kernel information and the task execution information should have certain regularities. Therefore, the preset target kernel information and the preset target task execution information can be obtained based on the above regularities.

[0074] Continuing with the above example, the kernel information is compared with the preset target kernel information to obtain a first comparison result; if the kernel information is different from the target kernel information, the first comparison result indicates that the kernel operation is abnormal; if the kernel information is the same as the target kernel information, the first comparison result indicates that the kernel operation is normal; the task execution information is compared with the preset target task execution information; if the task execution information is different from the target task execution information, the second comparison result indicates that the processor executes the instance task abnormally; if the task execution information is the same as the target task execution information, the second comparison result indicates that the processor executes the instance task normally.

[0075] Among them, if the first comparison result indicates that the kernel runs abnormally or the second comparison result indicates that the task is executed abnormally, the operating state of the processor is determined to be abnormal; if the first comparison result indicates that the kernel runs normally and the second comparison result indicates that the task is executed normally, the operating state of the processor is determined to be normal.

[0076] According to the technical solution provided in the embodiment of the present application, the kernel information is compared with the preset target kernel information to obtain a first comparison result; the task execution information is compared with the preset target task execution information to obtain a second comparison result; if the first comparison result represents a kernel operation abnormality or the second comparison result represents a task execution abnormality, the operating state of the processor is determined to be abnormal, thereby achieving accurate determination of the operating state of the processor when executing an instance task.

[0077] In some examples, such as Fig.11 As shown, after determining the operating state of the processor according to the kernel information and the task execution information, the method further includes:

[0078] S1101, if the running state of the processor is abnormal, control the processor to stop running the instance task;

[0079] S1102: Generate an abnormal warning prompt, and display the abnormal warning prompt through a display method provided by the vehicle.

[0080] Specifically, if the processor's operating state is abnormal, continuing to run the instance task may cause security vulnerabilities, data leakage, data corruption, and system crashes, and other security issues. Therefore, if the processor's operating state is abnormal, the processor is controlled to stop running the instance task to avoid causing more serious security issues.

[0081] In some examples, this example will generate an abnormal warning prompt and display the abnormal warning prompt through the display method provided by the vehicle, thereby prompting relevant personnel to repair the abnormality.

[0082] According to the technical solution provided in the embodiment of the present application, if the operating state of the processor is abnormal, the processor is controlled to stop running the instance task; an abnormal alarm prompt is generated, and the abnormal alarm prompt is displayed through the display method provided by the vehicle, thereby avoiding causing more serious safety problems, and the abnormal alarm prompt is displayed through the display method provided by the vehicle to prompt relevant personnel to repair the abnormality and ensure the stability of the vehicle.

[0083] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0084] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application.

[0085] This embodiment also provides a device for determining the operating state of a processor, such as Fig.12 As shown, the device comprises:

[0086] Configuration module 1201, used to determine the instance task corresponding to the processor in the vehicle, and generate a corresponding configuration file according to the instance task;

[0087] A monitoring module 1202, used to generate a monitoring application corresponding to the processor and the instance task according to the configuration file, the monitoring application being used to monitor the kernel information of the processor and the task execution information corresponding to the instance task;

[0088] The state module 1203 is used to receive the kernel information and task execution information returned by the monitoring application, and determine the running state of the processor according to the kernel information and the task execution information.

[0089] In some examples, the configuration file includes: a processor configuration file and a task configuration file. The root configuration module 1201 is also used to determine the task identifier, task quantity and task scheduling time corresponding to the instance task, and generate the task configuration file based on the task identifier, task quantity and task scheduling time; determine the processor identifier and core utilization rate corresponding to the instance task, and generate the processor configuration file based on the processor identifier and core utilization rate.
