[0002] The entire vehicle system is composed of many component controllers. Logs are the most common way to track problems. Each component can record program runtime logs during operation, so that maintenance or developers can track problems when problems occur. The loss or missing of log information will cause the failure or abnormality of components to occur, and the previous program running status cannot be traced, which will lead to bottlenecks in problem analysis, resulting in inefficient resolution of component failures or abnormalities, and may even make it impossible to track component failures or abnormalities.

When the program is running, they can only temporarily record key segment information in the memory at the expense of some resources, and the information will be cleared when the power is off.

[0028] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0029] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0030] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0031] The term "multiple" as used in this application refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0032] The existing vehicle system is composed of many component controllers. Logs are the most common way to track problems. Each component can record program runtime logs during operation to facilitate maintenance or developers to track problems when problems occur. Many components in the vehicle use MCU (microcontroller unit chip) without a file system. When the program is running, the log records can only be temporarily recorded in the memory at the expense of some resources. Key segment information is cleared when the power is off. There is no file storage to save log information, which leads to the loss or missing of log information of some components.

[0033] To this end, one aspect of the present application provides a log recording method for vehicle parts, which can be used in vehicle parts with a file system and in vehicle parts using an MCU without a file system to avoid the loss of log information.

[0034] First, please refer to Figure 1 , Figure 1 The log recording system of a vehicle component shown in an exemplary embodiment of the present application, wherein the MCU is an MCU vehicle component, of course Figure 1 The MCU components are temporarily shown in the figure. It is understandable that the logging system of the vehicle components may also contain non-MCU components. Figure 1 Not shown yet.

[0035] The relevant vehicle parts are located in the whole vehicle system, and the log recording device of the vehicle parts is arranged in the management vehicle parts. The management vehicle parts are high-performance vehicle parts. The log recording device of the vehicle parts can be used to implement the following vehicle parts log recording method.

[0036] Among them, each vehicle component is connected through a CAN bus (controller area network bus) or Ethernet. Of course, the end-to-end connection between each component is not limited to adjacent devices but can also span multiple vehicle components. The management of vehicle components synchronizes log information to the cloud server through the on-board gateway, on-board TBOX (on-board electrical components) and the network (internet).

[0037] Please refer to Figure 2 , Figure 2 1 is a flow chart of a log recording method for vehicle parts shown in an exemplary embodiment of the present application. The log recording method at least includes S210 to S230, which are described in detail as follows:

[0038] S210: Obtain preset configuration parameters.

[0039] In this embodiment, the log recording device for managing vehicle parts will first load configuration parameters, which include the vehicle part identification, the log storage path corresponding to the vehicle part, the periodic synchronization cloud time, the size of a single log file (file storage threshold) and the recording period of a single log file, the Ethernet UDP service listening port, the number of tasks that can be started to process log records (task processing threshold) and other information.

[0040] S220: Obtain the identification of the vehicle parts to be processed corresponding to the pending tasks in the log record queue, and match the corresponding target log storage path in the configuration parameters based on the identification of the vehicle parts to be processed.

[0041] Please refer to Figure 3Another exemplary embodiment of the present application shows a flow chart of a log recording method for vehicle parts, wherein after obtaining configuration parameters, the management of vehicle parts starts the main task (log processing module), opens the listening service for managing vehicle parts, opens the UDP listening port for Ethernet connection, opens the listening CAN message channel for CAN bus connection, and waits for the vehicle parts log transmission task.

[0042] In this embodiment, Figure 4 As shown, the transmission mode and the identification of the vehicle parts to be processed can be obtained in the pending task, so the transmission mode of transmitting the pending task to the log record queue can be obtained first; if the transmission mode is a method of transmitting data through Ethernet, the logical identification in the pending task is used as the identification of the vehicle parts to be processed; if the transmission mode is a method of transmitting data through a controller local area network, the controller local area network identification in the pending task is used as the identification of the vehicle parts to be processed.

[0043] Specifically, if the vehicle parts are connected via Ethernet, the transmission method is deemed to be data transmission via Ethernet, that is, the information transmitted from the vehicle parts to the management vehicle parts is in the UDP message format. If the vehicle parts are connected via the CAN bus, the transmission method is data transmission via the controller area network, that is, the information transmitted from the vehicle parts to the management vehicle parts is in the CAN message format. During operation, the vehicle parts transmit the data generated by the operation to the management vehicle parts. The main task of the management vehicle parts listens to the transmitted data and inserts it into the log record queue as a pending task. Then, based on the pending tasks in the log record queue, the management vehicle parts perform log recording on behalf of the management vehicle parts. After the management vehicle parts perform log recording for each vehicle part, it is synchronized to the cloud through the external communication module.

[0044] In a specific embodiment, regardless of whether the task to be processed is in the UDP message format or the CAN message format, it carries the corresponding vehicle component identifier to be processed. Therefore, the corresponding target log storage path can be matched in the configuration parameters through the vehicle component identifier to be processed of the task to be processed. Therefore, when the subsequent log processing module processes the tasks to be processed in the log record queue in sequence, it can record the corresponding data of the task to be processed based on the target log storage path, that is, the log information of the vehicle component to be processed corresponding to the task to be processed.

[0045] If the transmission mode is to transmit data via Ethernet, the data format of the task to be processed is as follows: Figure 5As shown, it includes UDP Header (User Datagram Protocol header file, occupying 8 bytes), LogicalId (logical identifier, occupying 2 bytes), DateLen (data length, occupying 2 bytes) and Date (data, occupying 0-1500 bytes), and the logical identifier is used as the identifier of the vehicle parts to be processed; and if the transmission method is a method of transmitting data through a controller area network, the controller area network identifier (CAN ID) in the task to be processed is used as the identifier of the vehicle parts to be processed, so that after determining the vehicle parts identifier, the target log storage path is matched.

[0046] In this embodiment, since there are two transmission modes, for the same vehicle parts, there may be the following Figure 6 The mapping table shown, that is, for a vehicle component name, it corresponds to a logical ID (identifier) ​​in the UDP message format and a CANID in the CAN message format. Therefore, when matching the target log storage path, it is generally matched through a two-tuple, that is, the vehicle component identifier and the transmission method. Specifically, the transmission method is used to determine whether the vehicle component identifier is a logical ID or a CANID, so as to match the corresponding vehicle component name and obtain the target log storage path.

[0047] In this embodiment, the configuration parameters may not contain the identification of the vehicle parts to be processed corresponding to the task to be processed, that is, the target log storage path cannot be matched in the configuration parameters. At this time, it may be because the vehicle parts to be processed generate log information for the first time. In this case, the vehicle parts identification and log storage path corresponding to the task to be processed can be added to the configuration parameters, and the newly added log storage path can be used as the target log storage path, and then wait for processing by the log processing module.

[0048] In some embodiments, there may be one or more log recording queues, which correspond to log processing modules, that is, each log processing module has a corresponding log recording queue, which records the data corresponding to the tasks to be processed, that is, the log processing module records the log information of the vehicle parts to be processed corresponding to the tasks to be processed in the corresponding log processing queue.

[0049] Specifically, the number of log processing modules can be detected; if the number of log processing modules is one, the task to be processed is transmitted to the log record queue corresponding to the log processing module based on the transmission time of the task to be processed; if the number of log processing modules is multiple, the task to be processed is transmitted to the log record queue corresponding to one of the multiple log processing modules based on the task processing threshold corresponding to the log processing module.

[0050] In a specific embodiment, if the number of the log processing module is one, all the transmitted tasks to be processed enter a log record queue to wait for processing according to the order of arrival.

[0051] If there are multiple log processing modules, at this time, there is a first log processing module, which is the first log processing module to be initialized. At this time, other log processing modules may not be initialized first, that is, the log processing queues corresponding to other log processing modules do not accept tasks to be processed.

[0052] If the number of pending tasks in the log record queue corresponding to the first log processing module is less than the task processing threshold, the pending tasks are transmitted to the log record queue corresponding to the first log processing module;

[0053] If the number of pending tasks in the log record queue corresponding to the first log processing module is not less than the task processing threshold, then the log record queue corresponding to the second log processing module other than the first log processing module among multiple log processing modules is initialized, and based on the number of pending tasks in the log record queue corresponding to the first log processing module and the number of pending tasks in the log record queue corresponding to the log processing module, the target log processing module is obtained to transfer the pending tasks to the target log processing module.

[0054] Specifically, there are multiple log processing modules. When the number of pending tasks in the log recording queue corresponding to the first log processing module is not less than the task processing threshold, which is preset in the configuration parameters. Generally speaking, the task processing threshold is the number of vehicle parts online multiplied by the log trigger frequency of a single vehicle part, the second log processing module is started, and the log processing queue corresponding to the second log processing module is initialized, and the next pending task entering the log processing queue is inserted into the log processing queue corresponding to the second log processing module.

[0055] In one embodiment, when a pending task enters a log processing queue, the number of pending objects in each log processing queue can be queried, and the log processing queue with a small number of pending objects can be used as the target log processing module to transfer the pending task to the target log processing module. In this way, the relative balance of the number of pending tasks in each log processing queue is ensured, so that the log processing module can process the pending tasks in parallel.

[0056] S230: Recording the data of the task to be processed based on the target log storage path.

[0057] In this embodiment, based on the target log storage path, the log file corresponding to the data of the task to be processed can be obtained. At this time, you can check whether the log file is recording data. If so, you can choose to create a new log file to store the data of the task to be processed or still store the data of the task to be processed in the log file.

[0058] In this embodiment, a log recording method for vehicle parts is proposed. The method can directly connect to the vehicle Ethernet or CAN interface or cross-device to store logs for vehicle parts without a file system and dynamically manage logs, and support high-concurrency processing. At the same time, the method can periodically report logs to the cloud to achieve multi-terminal recording, avoid the loss of log information, and facilitate development or operation and maintenance personnel to quickly analyze and solve problems. At the same time, the method has high portability and fast deployment, which saves time and economic costs for vehicle development, greatly reduces the development cycle, and can be quickly applied to multiple models.

[0059] In another exemplary embodiment of the present application, a method for recording data of a task to be processed is described in detail, such as Figure 7 As shown, in Figure 2 In S230 of the log recording method shown, S71 to S73 are further included, which are described in detail as follows:

[0060] S71: Detect whether a first log file exists based on the target storage path.

[0061] In this embodiment, based on the target storage path, a log file in which the data corresponding to the task to be processed is written can be obtained. If the log file is a log file that records data at the current time point, then the log file is the first log file. At the same time, the first log file can be obtained including a preset time range for recording data. The time range is the time period for recording data preset in the first log file. Within this time range, the first log file can write recorded data.

[0062] S72: If the first log file exists, detect whether the current time point is within a preset time range for recording data.

[0063] S73: If the current time point is not within the time range for recording data in the first log file, create a second log file and record the data of the task to be processed in the second log file.

[0064] In this embodiment, if the current time point is not within the time range for recording data in the first log file, the first log file can be directly closed, and a second log file can be created. The current time point is used as the starting time, and the starting time plus the single log file recording period (the recording period means that a single log folder only records the logs / data of pending tasks within the corresponding time of the period. For example, if the recording period is 30 minutes, it means that a single log folder only records logs within 30 minutes) is used as the end time. The start time and the end time are used as the time range for recording data in the second log file, and the second log file is named according to the time range for recording data in the second log file. The data of the pending tasks is written into the second log file to obtain the corresponding log information.

[0065] In some embodiments, if the current time point is within the time range of recording data in the first log file, detecting whether the size of the first log file after recording data exceeds the file storage threshold set for the first log file within the preset time range of recording data;

[0066] If the size of the first log file after recording the data exceeds the file storage threshold set for the first log file, a third log file is created, and the data of the task to be processed is recorded in the third log file.

[0067] Specifically, if the current time point is within the time range of the recorded data of the first log file, it can be calculated that within the preset time range of the recorded data, the size of the first log file after the recorded data is released exceeds the file storage threshold set for the first log file (which can be obtained in the configuration data). If it exceeds, the first log file can no longer write the data of the task to be processed. At this time, a third log file can be created, and the data of the task to be processed can be recorded in the third log file. The same as the second log file, the time range of the recorded data of the third log file is obtained, and the third log file is named according to the time range of the recorded data of the third log file, the data of the task to be processed is written into the third log file, and the corresponding log information is obtained.

[0068] In one embodiment, the pending tasks at the current time point within the preset time range of the recorded data can be recorded, and the pending tasks are taken as the first pending tasks; if the number of the first pending tasks is greater than the preset first threshold, the file storage threshold set for the log file is expanded.

[0069] Specifically, the number of the first tasks to be processed is greater than the preset first threshold. When the time range is less than the preset single-file recording time range for five consecutive times, it means that there are many logs that need to be recorded for the vehicle parts in the current period, that is, the number of tasks to be processed for the vehicle parts is large. At this time, the file storage threshold of the log file is dynamically adjusted according to the rules to avoid the creation of too many log files in a time period, affecting the device performance. Specifically, the file storage threshold can be expanded by an integer multiple to expand the file storage threshold set for the log file.

[0070] In some embodiments, the pending tasks in the log processing queue are processed separately, and if the pending tasks are processed multiple times in succession, the size of the first log file corresponding to the pending task after recording the data is greater than the file storage threshold set for the first log file, and the size of the first log file after recording the data is less than half of the file storage threshold, indicating that the vehicle parts have fewer files written to the log during the recording period, the recording period of the log file is dynamically adjusted to ensure that the size of each log file can reach saturation to avoid excessive file fragmentation. Specifically, the recording period of the log file can be expanded by an integer multiple to expand the recording period of the log file.

[0071] In this embodiment, a method of recording the data of the task to be processed is proposed. Through this method, it can be ensured that the log information of vehicle parts is stored, thereby improving the reliability of the log information. At the same time, it can reduce excessive log files and maximize the utilization of log recording resources.

[0082] The second processing unit is used to initialize the log record queue corresponding to the second log processing module other than the first log processing module among multiple log processing modules if the number of pending tasks in the log record queue corresponding to the first log processing module is not less than the task processing threshold, and obtain the target log processing module based on the number of pending tasks in the log record queue corresponding to the first log processing module and the number of pending tasks in the log record queue corresponding to the log processing module, so as to transfer the pending tasks to the target log processing module.
