[0018] The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Figure 1 The method for monitoring ECU operation data of the present disclosure is shown. In an embodiment of the present disclosure, the method includes:

[0021] Step S101, for each of the multiple operating data obtained by the electronic control unit ECU, determine whether the data exceeds the data threshold. If the data exceeds the data threshold, generate an alarm message, and store a first number of data collected before the data in a first storage space, where the first storage space is used to store abnormal data.

[0022] In this embodiment, the execution subject of the method for monitoring ECU operation data can collect operation data generated by the ECU during operation. For each of these operation data, the data is compared with a data threshold. When the comparison result exceeds the data threshold, an alarm message is generated to give an alarm. The storage space can correspond to a storage module.

[0023] For example, the operating data of the ECU may be a voltage inputted from outside to the ECU. The ECU may be of various types, such as an ECU in a vehicle.

[0024] Here, "exceed" usually means greater than, but in some cases it can also mean less than.

[0025] Step S102: store a second number of data whose collection time is later than the data in the first storage space, and determine whether there is data exceeding a data threshold in the second number of data.

[0026] In this embodiment, the execution subject may store a second number of data whose collection time is later than the data in the first storage space to determine whether there is data exceeding the data threshold in the second number of data.

[0027] Step S103: based on the judgment result, processing a third number of data whose collection time is later than the latest data among the second number of data.

[0028] In this embodiment, the execution subject may process the third number of data whose collection time is later than the latest data in the second number of data in various ways according to the judgment result. For example, the execution subject may store the data exceeding the data threshold in the third number of data whose collection time is later than the latest data in the second number of data in the first storage space.

[0029] This embodiment can filter and process the collected data through data thresholds, collect and store abnormal data and adjacent data of the abnormal data, thereby reducing storage pressure by storing valid data. Storing operation data by number is more compatible than storing by time in the prior art, and can avoid missing problematic data.

[0030] In some optional implementations of any embodiment of the present disclosure, the third number of data whose collection time is later than the latest data among the second number of data is processed according to the judgment result, including: if there is data in the second number of data that exceeds a preset threshold, the third number of data whose collection time is later than the latest data among the second number of data is stored in the first storage space; it is determined whether there is data in the third number of data that exceeds the preset threshold; if so, the fourth number of data whose collection time is later than the latest data among the third number of data is stored in the first storage space; if not, the execution is stopped.

[0031] In these implementations, when the result of determining whether there is any data exceeding the data threshold value among the plurality of operation data (such as the third data) is that there is, the other plurality of operation data collected later than the plurality of operation data are stored in the first storage space. And the determination of whether the other plurality of operation data exceeds the data threshold value continues. The execution can be stopped until the other plurality of operation data determined at the end does not exceed the data threshold value.

[0032] These implementations set data thresholds and critical intervals for data recording, which facilitates problem troubleshooting and analysis.

[0033] In some optional implementations of any embodiment of the present disclosure, the method further includes: if the data does not exceed the data threshold, determining whether the data is in a preset critical interval, the upper limit of the critical interval being the data threshold; based on the determination result of whether the data is in the preset critical area, storing the data in a storage space corresponding to the determination result.

[0034] Optionally, based on the judgment result of whether the data is in a preset critical area, the data is stored in a storage space corresponding to the judgment result, including: if the data is in a preset critical interval, an alarm message is generated, and the data is stored in a second storage space, and the second storage space is used to store suspected abnormal data; if the data is not in the preset critical interval, the data is stored in a third storage space, and the third storage space is used to store normal data.

[0035] In some optional implementations of any embodiment of the present disclosure, the method further includes: for the data to be processed obtained by the acquisition ECU, the data to be processed is split in the cache area according to the ID of the data to obtain the multiple operation data, and when storing, the data is stored according to the ID of the data. One ID corresponds to one operation parameter.

[0036] The storage module is partitioned and stores data by ID. The data is clear, and the over-threshold data has a comparison of the data changes before and after, making it easier to analyze the problem.

[0037] In some optional implementations of any embodiment of the present disclosure, the method further includes: connecting the acquisition module CAN and the ECU; and acquiring data from the ECU through the CAN to obtain the data to be processed.

[0038] The present disclosure also provides a method for monitoring ECU operating data, which is as follows:

[0039] First, power on and initialize each module of the monitoring system, set the data threshold and critical interval under different IDs. Connect the ECU to the acquisition module through CAN, power on the ECU and run it continuously, and send the ECU data to be monitored to the monitoring system through CAN messages.

[0040] The acquisition module continuously collects ECU data messages and sends them to the cache module, which splits the data by ID. According to the data thresholds set for each ID, it determines whether the data exceeds the limit. There are four situations:

[0041] (1) If the data exceeds the set threshold, the alarm module will sound an alarm, and the cache module will send the first 50 data with the same ID to the storage module 1 and mark the ID; the subsequent 50 data with the same ID will be sent to the storage module 1 after judging the threshold. If there is still data exceeding the threshold, the threshold judgment will be postponed for 50 data with the same ID and sent to the storage module 1.

[0042] (2) If the data does not exceed the predetermined threshold, continue to determine whether the data is within the set critical interval.

[0043] (3) If the data is in the critical range, the alarm module issues a fault warning, and the cache module sends the critical data and its ID to the storage module 2.

[0044] (4) If the data is not in the critical interval, indicating that the data is normal, only the first collected data is sent to the storage module 3 for the ID within a certain number of collection times.

[0045] Multiple groups of data are stored in storage modules 1, 2, and 3 according to IDs.

[0046] Take the ECU data with ID 0x01FF as an example, its standard value is a. Collect ECU data and cache (a1, a2, a3, ..., a n-1 ,a n ). Connect the ECU to the monitoring system, power on the ECU and initialize the modules of the monitoring system, set the data threshold to A, and the critical interval to [B, A].

[0047] Data cache value a at a certain moment n >A, the alarm module issues a fault alarm and sets (a1, a2, a3, ..., a n-1 ,a n ) is sent to storage module 1, and the subsequent (a n+1 ,a n+2 ,...,a n+49 ,a n+50 ) after judging the threshold, it is sent to storage module 1.

[0048] Data cache value a at a certain moment m ∈[B,A], the alarm module will warn of a fault and m Sent to storage module 2; if (a m+1 ,a m+2 ,a m+3 ,...,a m+100 ) are normal, then take a m+1 Send to storage module 3.

[0049] like Figure 2 As shown, another flow chart of the method for monitoring ECU operating data is shown.

[0050] The present disclosure also provides a system for monitoring ECU operation data, the system includes an ECU and a monitoring device, the monitoring device includes an acquisition module, a cache module, a storage module and an alarm module; the acquisition module is used to acquire multiple operation data from the ECU; the cache module is used to determine whether each data in the multiple operation data exceeds a data threshold, and if the data exceeds the data threshold, send the data to the alarm module so that the alarm module generates an alarm message; send a first number of data whose acquisition time is earlier than the data to the first storage module so that the first storage module stores the data; send a second number of data whose acquisition time is later than the data to the first storage module so that the first storage module stores the data; and according to the judgment result, process a third number of data whose acquisition time is later than the latest data in the second number of data.

[0051] Optionally, the ECU is connected to CAN; the acquisition module is further used to collect data from the ECU through the CAN, obtain the data to be processed, and send the data to be processed to the cache module in real time.

[0052] The collected data is directly sent to the cache module for processing, which reduces the parallel processing pressure of the processor, has strong real-time performance, and faults can be reported in time. At the same time, it reduces storage pressure.

[0053] like Figure 3 As shown in the figure, the acquisition module collects the data of the ECU through the controller area network bus CAN. The cache module processes the collected data and sends a message to the alarm module to realize the alarm and sends a message to the storage module to realize the storage.

[0054] The system for monitoring ECU operation data includes a monitoring system composed of an acquisition module, a cache module, a storage module and an alarm module, such as Figure 3 As shown, including:

[0055] The acquisition module is connected to the ECU via CAN;

[0056] The cache module is used to process the ECU data collected by the acquisition module. When the cache of the same ID data exceeds 100, the excess part will be erased in chronological order.

[0057] The alarm module can issue an alarm when abnormalities occur in the collected data;

[0058] The storage module is divided into three storage areas for storing processed ECU data of different categories.
