[0018] The present disclosure will be further described below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that, for the sake of description, only the parts related to the application are shown in the drawings.

[0019] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings and embodiments.

[0020] Figure 1 A method for monitoring ECU operating data is shown. In an embodiment of the present disclosure, the method comprises:

[0021] In step S101, for each of the plurality of operating data collected by the electronic control unit ECU, it is determined whether the data exceeds the data threshold. If the data exceeds the data threshold, an alarm information is generated, and the first number of data before the data in the collection time is stored in the first storage space, and the first storage space is used to store abnormal data.

[0022] In this embodiment, the execution subject of the method for monitoring ECU operating data can collect the operating data generated by the ECU during operation. For each of these operating data, the data and the data threshold are compared. In the case of exceeding the data threshold, an alarm information is generated to alarm. The storage space can correspond to the storage module.

[0023] For example, the operating data of the ECU can be the voltage input to the ECU from the outside. The ECU can be various, such as the ECU in the vehicle.

[0024] Here, exceeding usually means greater than, and in some cases can also mean less than.

[0025] In step S102, the second number of data after the data in the collection time is stored in the first storage space, and it is determined whether there is data exceeding the data threshold in the second number of data.

[0026] In this embodiment, the above execution subject can store the second number of data after the data in the collection time in the first storage space. To determine whether there is data exceeding the data threshold in the second number of data.

[0027] In step S103, according to the determination result, the third number of data after the latest data in the second number of data in the collection time is processed.

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

[0029] The embodiment can filter the collected data by the data threshold, collect and store the abnormal data and the adjacent data of the abnormal data, thereby reducing the storage pressure by storing the effective data. The running data is stored according to the quantity, which is more compatible than the storage according to the time in the prior art, and can avoid omission of the problem data.

[0030] In some optional implementations of any embodiment of the disclosure, the processing of the third quantity of data with the latest collection time later than the latest data in the second quantity of data according to the judgment result includes: if there is data exceeding the preset threshold in the second quantity of data, storing the third quantity of data with the latest collection time later than the latest data in the second quantity of data to the first storage space; judging whether there is data exceeding the preset threshold in the third quantity of data; if there is, storing the fourth quantity of data with the latest collection time later than the latest data in the third quantity of data to the first storage space; and if not, stopping execution.

[0031] In these implementations, if the result of judging whether there is data exceeding the data threshold in the plurality of running data (such as the third quantity of data) is that there is, the first storage space can store another plurality of running data with the latest collection time later than the plurality of running data. And continue to judge whether the other plurality of running data exceeds the data threshold. Until the last judged other plurality of running data does not exceed the data threshold, the execution can be stopped.

[0032] These implementations respectively set the data threshold and the critical interval for data recording, which facilitates problem analysis and troubleshooting.

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

[0034] Optionally, the step of storing the data in the storage space corresponding to the judgment result based on whether the data is in a preset critical region includes: if the data is in a preset critical range, generating an alarm message and storing the data in a second storage space, the second storage space being used to store suspected abnormal data; if the data is not in a preset critical range, storing the data in a third storage space, the third storage space being used to store normal data.

[0035] In some optional implementations of any embodiment of this disclosure, the method further includes: for the data to be processed obtained from the ECU, splitting the data to be processed in a buffer according to the data ID to obtain the plurality of running data, and storing them according to the data ID during storage. One ID corresponds to one running parameter.

[0036] The storage module is partitioned and stores data by ID, making the data clear. Furthermore, data exceeding the threshold can be compared with changes in the data before and after, making it easier to analyze problems.

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

[0038] This disclosure also provides a method for monitoring ECU operating data, as follows:

[0039] First, power on and initialize all modules of the monitoring system, setting data thresholds and critical ranges for different IDs. Connect the ECU to the acquisition module via CAN, power on the ECU and run it continuously, sending the ECU data to be monitored to the monitoring system via CAN messages.

[0040] The acquisition module continuously collects ECU data packets and sends them to the buffer module, which then splits the data by ID. Based on the pre-defined data thresholds for each ID, it determines whether the data exceeds the limits, categorizing the cases into four scenarios:

[0041] (1) If the data exceeds the set threshold, the alarm module issues an alarm, the cache module sends the first 50 data with the same ID to the storage module 1 and marks the ID; the next 50 data with the same ID are sent to the storage module 1 after the threshold is judged. If there is still data exceeding the threshold, the next 50 data with the same ID are sent to the storage module 1 after the threshold is judged.

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

[0043] (3) If the data is in the critical range, the alarm module will issue a fault warning and the cache module will send 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, then only the first collected data of the ID is sent to the storage module 3 within a certain number of collection times.

[0045] Multiple sets of data are stored in storage modules 1, 2, and 3 according to the ID.

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

[0047] At a certain time, the data cache value a n > A, the alarm module sends a fault alarm, and sends (a1, a2, a3,..., a n-1 , a n ) to the storage module 1, and sends the subsequent (a n+1 , a n+2 ,..., a n+49 , a n+50 ) to the storage module 1 after thresholding.

[0048] At a certain time, the data cache value a m ∈ [B, A], the alarm module sends a fault warning, and sends a m to the storage module 2; if (a m+1 , a m+2 , a m+3 ,..., a m+100 ) are normal, then take a m+1 to send to the storage module 3.

[0049] As shown in Figure 2 , another flowchart of the method of monitoring ECU operating data is shown.

[0050] The disclosure also provides a system for monitoring ECU operation data, the system comprising an ECU and a monitoring device, the monitoring device comprising an acquisition module, a cache module, a storage module and an alarm module; the acquisition module is configured to acquire a plurality of operation data of the ECU; the cache module is configured to determine, for each of the plurality of operation data, whether the data exceeds a data threshold, and if the data exceeds the data threshold, send the data to the alarm module to make the alarm module generate alarm information; send the first number of data before the data in terms of acquisition time to the first storage module for storage; send the second number of data after the data in terms of acquisition time to the first storage module for storage; and process the third number of data after the latest data of the second number of data in terms of acquisition time according to the determination result.

[0051] Optionally, the ECU is connected with a CAN; and the acquisition module is further configured to acquire data of the ECU through the CAN to obtain the to-be-processed data, and send the to-be-processed data to the cache module in real time.

[0052] The acquired 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 can report faults in time, and meanwhile reduces the storage pressure.

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