[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0026] 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 can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0027] The flowcharts shown in the drawings are only illustrative, and are not necessarily required to include all contents and operations / steps, nor are they necessarily executed in the order described. For example, some operations / steps can be further broken down, and some operations / steps can be combined or partially combined, so the actual execution order can be changed according to actual conditions.

[0028] “Multiple” mentioned in the present application refers to two or more. “And / or” describes the association between the associated objects, indicating that there can be three relationships, for example, A and / or B can represent the three cases of A alone, A and B together, and B alone. The character “ / ” generally represents that the associated objects before and after are in an “or” relationship.

[0029] The prior art provides a remote calibration data acquisition method, which acquires controller internal calibration data in real time through a remote online device. Although the engineer does not have to be directly on site and can acquire controller internal data in the office to improve efficiency, long-time driving will generate a large amount of calibration data, and a test data segment will be very large or many calibration test data segments, which is inefficient for analyzing problems and cannot very quickly locate the time and corresponding content of the calibration problem data. The calibration engineer needs to review a large amount of data, rely on the memory and characteristic operation at the time to try to lock the problem occurrence time point. This method is simple and has poor effect, and the phenomenon of being unable to lock the problem data occurrence time often occurs, resulting in very low analysis efficiency.

[0030] 1. Calibration data acquisition. The ordinary data acquisition device follows the vehicle and only passively acquires all calibration data signals, and cannot actively mark the test data based on the problem occurrence time point to facilitate the engineer to lock the problem occurrence time and find the characteristic data corresponding to the problem.

[0031] 2. Problem occurrence time record content is simple. When a problem occurs during remote driving of the vehicle, the current data acquisition device only records the current controller internal calibration data and CAN message signals, etc., and does not acquire the current driver audio, vehicle-mounted camera video recording, weather, road conditions, altitude, external test sensors, etc. Information is not useful for full problem analysis and investigation.

[0032] 3. Trigger function. The current data acquisition device is only passively followed by the vehicle for data acquisition, lacks a human-computer interaction channel, and cannot support the needs of the driver to record the current problem occurrence time data for mar marking or efficiently record all key test information at the current time.

[0033] 4. The current remote calibration device is relatively independent, does not effectively utilize vehicle voice control commands for signal integrated development, and cannot recognize vehicle voice control operations.

[0034] In view of the prior art problems described above, the application provides a remote calibration data recording method and device, a computer device and a storage medium to solve the problems in the prior art. The technical solution of the application is described in detail in the following embodiments.

[0035] It should be noted that the remote calibration data is collected by a remote calibration device, which is installed on a vehicle, usually placed on the outer surface of the vehicle body, and used to collect vehicle body data and surrounding environment data during vehicle driving. The remote calibration device caches the collected data locally, but the local storage is limited, and the subsequent collected data will overwrite the previously collected data after a certain period of time. Therefore, it is necessary to record and store the collected data. The remote calibration device is installed on the vehicle body, and under normal circumstances, only low-precision, low-requirement, and a certain amount of test data are recorded. For example, XCP data collection based on A2L also supports fixed-precision CAN / CANFD data, the former can actively set the sampling period (1-500 ms or polling mode), and the latter is a fixed-step data collection. In the following, the "trigger function" is a high-precision recording function (i.e., a high-precision recording instruction is issued), and the mark is a data marker.

[0036] Figure 1 A flowchart of one embodiment of the remote calibration data recording method of the application is shown, which is executed by a computer device. Please refer to Figure 1 The method includes the following steps:

[0037] Step S110: In the process of recording data, in response to a high-precision recording instruction, the starting time and the ending time of high-precision recording are determined according to the receiving time corresponding to the high-precision recording instruction.

[0038] In the process of recording data, it also includes regular recording; the starting time is less than the receiving time, and the ending time is greater than the receiving time.

[0039] Specifically, when the driver has a demand or meets a preset vehicle condition, trigger the high-precision, full-quantity data high-specification test data through the trigger function, and the control command issuing time (i.e., the receiving time) is x. x-a is the starting time, and x+b is the ending time. a / b can set the time length based on the demand.

[0040] Step S120: Collecting the data collected at each time between the starting time and the ending time for high-precision recording.

[0041] The high-precision data recorded by the high-precision recording has more types than the normal data recorded by the normal recording, and the granularity of the high-precision data is smaller than the granularity of the normal data.

[0042] Specifically, the data in [x-a, x+b] will be recorded by high-precision recording. The high-precision data in this time period is recorded and stored in the high-precision data (i.e., high-precision data) buffer, avoiding collecting high-precision data (i.e., high-precision data) all the time, wasting device storage space and traffic resources. The high-precision recording changes the previous data recording from 100 ms or slower to 1-10 ms high-precision. The granularity is the smallest unit of data, and the granularity of high-precision data is smaller, which means that the accuracy of high-precision data is higher, and the types are more. The data types of high-precision data also include current driver audio, vehicle camera video recording, weather, road conditions, altitude, external test sensors, and other information.

[0043] The Trigger function triggers the default collection of normal-precision data, but the high-precision data collection list and high-precision collection frequency are prepared in advance. After the Trigger function is triggered, the high-precision collection mode is switched to within the [x-a, x+b] time.

[0044] Beneficial effects: by responding to the high-precision recording instruction during the recording process, determining the start time and end time of high-precision recording according to the corresponding receiving time of high-precision recording, and recording the data collected at each time between the start time and the end time. Thus, high-precision recording of the target data occurrence time is realized during the recording process, which can quickly analyze problems based on the recorded high-precision data, thereby saving the human and time costs of engineers reviewing data and greatly improving problem analysis efficiency. At the same time, part of the high-precision data and part of the normal data are obtained, which can avoid collecting high-precision data all the time and waste device storage space and traffic resources.

[0045] In some embodiments, the high-precision recording instruction is issued by the user end or the vehicle end; before step S110, it further includes receiving the high-precision recording instruction issued by the user end and / or the vehicle end.

[0046] The high-precision recording instruction includes the user end issuing a high-precision recording instruction through voice, the user end issuing a high-precision recording instruction through voice or a preset button to control the vehicle end, and the vehicle end issuing a high-precision recording instruction when the vehicle condition meets a preset vehicle condition.

[0047] Specifically, the remote calibration device receives the sensor signal through the physical interface button to start the trigger function for high-precision measurement of test data and adds a mark label. The remote calibration device is started through vehicle intelligent voice control ("Xiao Yi" or "record problem") to start the trigger function and add a mark label. The remote calibration device is started through voice control ("start device recording") to start the trigger function and add a mark label. Through preset vehicle conditions, the vehicle end automatically issues a high-precision recording instruction after meeting the preset vehicle conditions; once the preset vehicle conditions are met during data collection, it is considered that the preset vehicle conditions are met, and high-precision recording can be performed on the current situation.

[0048] The above are all ways to issue a high-precision recording instruction to control the remote calibration device to perform high-precision recording.

[0049] Beneficial effects: The user end and / or the vehicle end can both issue a high-precision recording instruction to control the remote calibration device to perform high-precision recording, which reflects the multiple feasibility of issuing a high-precision recording instruction, and fully utilizes the existing vehicle end device to control the remote calibration device outside the vehicle, improving the operability of the scheme. Further refine the way to issue a high-precision recording instruction, enrich and perfect the scheme of the present application.

[0050] In some embodiments, the high-precision recording instruction is issued by a target user, such as Figure 2 As shown in the method further comprises:

[0051] Step S210: Detecting whether there is a historical carrier file of the target user.

[0052] The historical carrier file is used to store high-precision data recorded by high-precision recording.

[0053] Specifically, if there is, it indicates that the target user has issued a high-precision recording instruction, and a historical carrier file corresponding thereto has been generated, which records historical high-precision data.

[0054] Step S220: If there is, store the high-precision data corresponding to each time between the start time and the end time of recording in the historical carrier file to obtain an updated historical carrier file.

[0055] Specifically, if there is, store the high-precision data recorded by the current high-precision recording in the historical carrier file to obtain an updated historical carrier file.

[0056] Beneficial effects: Detecting whether there is a historical carrier file of the current user, if there is, storing the high-precision data corresponding to the high-precision recording instruction issued by the current user in the corresponding historical carrier file to form exclusive high-precision data of the current user, which is convenient for subsequent current user to call and analyze, and improves the analysis efficiency of the subsequent current user.

[0057] In some embodiments, as shown in Figure 3 S210 further comprises:

[0058] S211: If not, a carrier file of the target user is established according to the identity information of the target user.

[0059] Specifically, if not, a carrier file belonging to the target user is established according to the identity information of the target user. The high-precision data recorded by the current high-precision recording is recorded and stored. The data file name (i.e. the file name of the carrier file of the target user) can be directly generated and named by the voice operation of the target user.

[0060] The identity information includes one or more of voiceprint information, face information, and iris information.

[0061] S212: The high-precision data corresponding to each time between the start time and the end time of the recording is stored in the carrier file to obtain a historical carrier file of the target user.

[0062] Specifically, after the establishment, the high-precision data recorded by the current high-precision recording is recorded in the carrier file. When high-precision recording is performed subsequently, the carrier file here is already a historical carrier file of the target user.

[0063] Beneficial effects: The case where there is no historical carrier file is further refined. By establishing a carrier file and recording the current high-precision data in the established carrier file, a historical carrier file of the target user is obtained. A carrier file exclusively belonging to the target user is established, the case where there is no historical carrier file is refined, and the present scheme is further improved.

[0064] In some embodiments, as shown in Figure 4 S110, further comprising:

[0065] S310: A time directory of the high-precision recording is established according to the start time and the end time.

[0066] Specifically, a mark label is set to mark a flag bit (i.e. to establish a time directory of the high-precision recording), so as to facilitate quick positioning of the data at the time when the problem occurs.

[0067] S320: A target time directory corresponding to the recording data is obtained according to the collection time of the recording data and the time directory of the high-precision recording.

[0068] The recording data includes high-precision data recorded by the high-precision recording and regular data recorded by the regular recording.

[0069] Specifically, the final target time directory is composed of multiple time-continuous time periods, each of which corresponds to a time length of a regular record or a high-precision record. Since the time of the high-precision record is marked in the previous step, the time period in which the high-precision record is located can be quickly seen from the target time directory, and the high-precision data corresponding to the record can be quickly seen by selection.

[0070] Beneficial effects: By establishing a target time directory for the entire recording data process, the time period in which the high-precision record is located is marked in the target time directory. The corresponding start time and end time can be used to quickly find the corresponding high-precision record, which is convenient for different users to quickly find and determine. At the same time, the analyst (i.e., the user) can quickly view the corresponding high-precision record and its recorded high-precision data according to the target time directory, which greatly improves the speed of subsequent data analysis.

[0071] In some embodiments, when the real vehicle driver finds that a problem occurs, the vehicle control voice command such as "small art" or "record problem" is transmitted to the remote calibration device, or the trigger function is activated by the remote calibration device supporting voice calling "start problem recording". At this time, the data acquisition device marks the calibration data after receiving the voice command. The mark bookmark mainly includes data recording time, corresponding software version, vehicle mileage, driving time and other key information. The information after the mark is generated is uniformly uploaded to the server for management and can be directly found, downloaded and online analyzed.

[0072] In some embodiments, as shown in Figure 5 The method further includes:

[0073] Step S410: According to the different recording data modes, a plurality of sub-files are generated.

[0074] The sub-files include high-precision record files and regular record files.

[0075] Specifically, the recording data mode includes high-precision recording and regular recording.

[0076] Step S420: The sub-files are sequentially sorted according to the start collection time of the corresponding recording data, to obtain the target sorting of the sub-files.

[0077] Specifically, the sub-files are sequentially sorted according to the collection time.

[0078] Step S430: In the target sorting, the multiple sub-files which are high-precision record files or regular record files between adjacent sub-files are merged.

[0079] Specifically, if the adjacent sub-files are both high-precision recording files or both regular recording files, as long as they are continuously adjacent in the target order, they need to be merged, and the continuous parts, no matter how many, are regarded as being merged into one.

[0080] Beneficial effects: The sub-files are sorted according to the collection time sequence, and the continuously adjacent sub-files of the same type are merged. Therefore, the number of sub-files is reduced, and the storage burden is further reduced.

[0081] In some embodiments, after step S120, the method further includes: sending the recorded data to the vehicle central control screen for display, so that the user can analyze the data in real time.

[0082] The recorded data includes high-precision data recorded by high-precision recording and regular data recorded by regular recording.

[0083] Specifically, the data obtained by the remote calibration device can be directly projected and displayed on the central control screen of the vehicle central control display. The past data can only be analyzed after being downloaded on the engineer's notebook, which is a waste of the utilization rate of the vehicle central control screen. The vehicle central control display can support online display requests of remote devices. In the experiment, the calibration and measurement signals are directly displayed on the vehicle central control screen in real time, which fully utilizes the vehicle central control screen to support the test.

[0084] Technical effects: By displaying the recorded data on the vehicle display screen, the user can analyze the data in real time. This implementation allows the user to analyze the data in real time, fully utilizes the vehicle equipment, avoids waste, and improves the analysis efficiency.

[0085] In some embodiments, the data recorded by the remote calibration device can be supported on the cloud through 5G / WIFI. The local engineer can analyze the mark data and the normal data by accessing the network, which is convenient for the engineer to locate the problem data and analyze the data in the first time.

[0086] Figure 6 The structure of the embodiment of the remote calibration data recording device of the present application is shown. Please refer to Figure 6 As shown, the device 500 includes a start and end time determination module 510 and a high-precision recording module 520.

[0087] The start and end time determination module 510 is configured to, in the process of recording data, in response to a high-precision recording instruction, determine the start time and the end time of high-precision recording according to the receiving time corresponding to the high-precision recording instruction; wherein the process of recording data further includes regular recording; the start time is less than the receiving time, and the end time is greater than the receiving time.

[0088] The high-precision recording module 520 is configured to record data collected at each time point between the start time point and the end time point; the high-precision data recorded by the high-precision recording has more types than the conventional data recorded by the conventional recording, and the granularity of the high-precision data is smaller than the granularity of the conventional data.

[0089] Beneficial effects: by determining the start time point and the end time point of the high-precision recording according to the receiving time point corresponding to the high-precision recording in response to the high-precision recording instruction during the recording process, and recording data collected at each time point between the start time point and the end time point, the high-precision recording of the target data occurrence time point during the recording process is realized, and the problem analysis efficiency is greatly improved.
