[0025] 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.

[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 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.

[0027] 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.

[0028] 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.

[0029] The prior art provides a remote calibration data acquisition method, which acquires the internal calibration data of the controller in real time through a remote online device. Although the engineer can acquire the internal data of the controller without sitting in the office directly on site, which improves efficiency, a large amount of calibration data will be generated due to long-term driving. One section of test data will be very large or there will be many sections of calibration test data, which is inefficient for problem analysis. It is impossible to quickly locate the time when the calibration problem data occurs and the corresponding content. The calibration engineer needs to review a large amount of data and try to lock the time point when the problem occurs based on the memory and feature operations at that time. This method is crude and ineffective. It is often impossible to lock the time when the problem data occurs and thus fail to analyze the problem, resulting in extremely low analysis efficiency.

[0030] 1. Calibration data collection. Ordinary data collection equipment only passively collects all calibration data signals after following the vehicle, and cannot actively mark the test data based on the time when the problem occurs to facilitate engineers to identify the time when the problem occurs and find the characteristic data corresponding to the problem.

[0031] 2. The recorded content is simple when the problem occurs. When a problem occurs during remote driving, the current data acquisition equipment only records the calibration data and CAN message signals inside the current controller, and does not collect the current driver audio, vehicle camera video recording, weather, road conditions, altitude, external test sensors and other information, and does not fully utilize the problem analysis and investigation.

[0032] 3. Trigger function. The current data acquisition equipment is only installed on the vehicle to passively follow the vehicle for data acquisition. It lacks a human-computer interaction channel and cannot support the driver's needs to record the data at the time when the current problem occurs for mar marking or efficiently record all key test information at the current moment.

[0033] 4. The current remote calibration equipment is relatively independent, does not effectively utilize vehicle voice control commands for signal integration development, and is unable to recognize vehicle voice control operations.

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

[0035] It should be noted that the remote calibration data is collected by the remote calibration device, and the remote calibration device is installed on the vehicle, usually placed on the outer surface of the vehicle body, to collect the vehicle body data and surrounding environment data during driving; the remote calibration device will cache the collected data locally, but the local storage is limited, and the subsequent collected data will overwrite the previous collected data after a certain period of time. Therefore, it is necessary to record and store the collected data. The remote calibration device is outside the vehicle body and is connected to the vehicle-side controller by wired connection. The data record is recorded in the remote calibration device and can be sent to the cloud server through the communication connection. The remote calibration device is installed on the vehicle, and under normal circumstances, only low-precision, low-requirement, and a certain amount of test data are recorded. For example, XCP data acquisition based on A2L also supports CAN / CANFD data with fixed acquisition accuracy. The former can actively set the sampling period (1-500ms or polling mode), and the latter CAN / CANFD data is fixed-step acquisition. In the following text, the "trigger function" is to trigger the high-precision recording function (that is, to issue a high-precision recording instruction), and the mark mark is to mark the data.

[0036] Figure 1 A flowchart of an embodiment of a method for recording remote calibration data of the present application is shown, and the method is executed by a computer device. Figure 1 As shown, the method comprises the following steps:

[0037] Step S110: During the data recording process, in response to the high-precision recording instruction, the start time and the end time of the high-precision recording are determined according to the receiving time corresponding to the high-precision recording instruction.

[0038] The data recording process also includes regular recording; the start time is less than the receiving time, and the end time is greater than the receiving time.

[0039] Specifically, when the driver has a demand or the preset vehicle condition is met, the trigger function is used to trigger high-precision, full-volume high-specification test data, and the control command is issued at x (i.e., the receiving time). xa is the starting time, and x+b is the ending time. a / b can be set based on demand.

[0040] Step S120: Record the data collected at each time between the start time and the end time with high precision.

[0041] Among them, the types of high-precision data recorded in high-precision records are more than the types of conventional data recorded in conventional records, and the granularity of high-precision data is smaller than that of conventional data.

[0042] Specifically, the data within [xa,x+b] will be recorded with high precision. Data is recorded with high precision during this time period and stored in a high-precision data (i.e., high-precision data) buffer to avoid collecting high-precision data (i.e., high-precision data) throughout the entire process, which wastes device storage space and traffic resources. High-precision recording changes the previous data recording from 100ms or slower to 1-10ms with high precision. Granularity is the smallest unit of data. The smaller the granularity of high-precision data, the higher the precision and the more types of high-precision data. The data types of high-precision data also include information such as current driver audio, on-board camera video recording, weather, road conditions, altitude, external test sensors, etc.

[0043] Before the Trigger function is triggered, normal precision data is collected by default, but a 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 within the time [xa,x+b].

[0044] Beneficial effect: By responding to the high-precision recording instruction during the data recording process, according to the corresponding receiving time of the high-precision recording, the starting time and the ending time of the high-precision recording are determined; and the data collected at each time between the starting time and the ending time are recorded with high precision. Thus, the high-precision recording of the time when the target data occurs is achieved during the data recording process, and then the problem can be quickly analyzed based on the recorded high-precision data, thereby saving the manpower cost and time cost of engineers flipping through the data, and greatly improving the efficiency of problem analysis. At the same time, obtaining part of the high-precision data and part of the conventional data can avoid the whole process of collecting high-precision data and wasting equipment 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 also includes: receiving the high-precision recording instruction issued by the user end and / or the vehicle end.

[0046] Among them, the high-precision recording instructions include the user end issuing high-precision recording instructions through voice, the user end controlling the vehicle end to issue high-precision recording instructions through voice or preset buttons, and the vehicle end issuing high-precision recording instructions when the vehicle condition meets the preset vehicle condition conditions.

[0047] Specifically, the remote calibration device receives sensor signals through the physical interface buttons to turn on the trigger function for high-precision measurement of the test data, and adds a mark tag. The remote calibration device is linked to the vehicle's intelligent voice control ("Xiaoyi" or "Record the problem") to turn on the trigger function and add a mark tag. The trigger function is turned on and a mark tag is added through the remote calibration device voice control ("Turn on device recording"). By presetting the vehicle condition, after the preset vehicle condition is met, the vehicle side automatically issues a high-precision recording instruction; once the preset vehicle condition is detected when collecting data, it is considered that the preset vehicle condition is met, and the situation at the time can be recorded with high precision.

[0048] The above mentioned are all ways to issue high-precision recording instructions to control remote calibration equipment to perform high-precision recording.

[0049] Beneficial effects: High-precision recording instructions can be issued by the user end and / or the vehicle end to control the remote calibration equipment to perform high-precision recording, which reflects the multiple feasibility of issuing high-precision recording instructions. At the same time, it also makes full use of the existing vehicle-end equipment, and can control the remote calibration equipment outside the vehicle from inside the vehicle, improving the operability of the solution. The method of issuing high-precision recording instructions is further refined, enriching and improving the application solution.

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

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

[0052] Among them, the historical carrier file is used to store the high-precision data recorded by the high-precision record.

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

[0054] Step S220: If it exists, the high-precision data corresponding to each moment between the start time and the end time of the record is stored in the history carrier file to obtain an updated history carrier file.

[0055] Specifically, if it exists, the high-precision data record of this high-precision record is stored in the history carrier file to obtain an updated history carrier file.

[0056] Beneficial effect: Detect whether there is a historical carrier file of the current user. If so, store the high-precision data corresponding to the high-precision recording instruction issued by the current user in the corresponding historical carrier file, forming exclusive high-precision data of the current user, which is convenient for subsequent retrieval and analysis by the current user, thereby improving the analysis efficiency of the subsequent current user.

[0057] In some embodiments, Figure 3 As shown, step S210 further includes:

[0058] Step S211: If it does not exist, create a carrier file of the target user according to the identity information of the target user.

[0059] Specifically, if it does not exist, a carrier file belonging to the target user is created according to the identity information of the target user. The high-precision data recorded in this 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 through the voice operation of the target user.

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

[0061] Step S212: Store the high-precision data corresponding to each moment between the start time and the end time of the record into a carrier file to obtain a historical carrier file of the target user.

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

[0063] Beneficial effect: The situation where there is no historical carrier file is further refined. By establishing a carrier file, the high-precision data is recorded in the established carrier file to obtain the historical carrier file of the target user. A carrier file dedicated to the target user is established, and the situation where there is no historical carrier file is refined, further improving this solution.

[0064] In some embodiments, Figure 4 As shown, after step S110, the following steps are also included:

[0065] Step S310: Create a time directory of high-precision recording according to the start time and the end time.

[0066] Specifically, a mark tag is added to set a flag (i.e., a time directory with high-precision records is established) to facilitate rapid location of data at the time when the problem occurred.

[0067] Step S320: Obtain a target time directory corresponding to the recorded data according to the acquisition time of the recorded data and the time directory of the high-precision record.

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

[0069] Specifically, the final target time directory is composed of multiple continuous time periods, each time period corresponds to the corresponding duration of a conventional record or a high-precision record. Since the time of the high-precision record has been 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 of the corresponding record can be quickly viewed by selecting it.

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

[0071] In some embodiments, when the actual vehicle driver finds that a problem has occurred, the vehicle control voice command such as "Xiaoyi" or "record problem" command is transmitted to the remote calibration device, or the remote calibration device supports voice call "start problem recording" and other activation trigger functions. At this time, the data acquisition device marks the calibration data after receiving the voice command. The mark bookmark mainly contains key information such as data recording time, corresponding software version, vehicle mileage, driving time, etc. The information generated by the mark will be uniformly uploaded to the server management and the corresponding calibration test data can be directly searched, downloaded, and analyzed online.

[0072] In some embodiments, Figure 5 As shown, the method also includes:

[0073] Step S410: Generate multiple sub-files according to different data recording methods.

[0074] Among them, the sub-files include high-precision record files and regular record files.

[0075] Specifically, the data recording methods include high-precision recording and conventional recording.

[0076] Step S420: sorting the sub-files in order of the start collection time of the corresponding record data to obtain the target sorting of the sub-files.

[0077] Specifically, each sub-file is obtained and sorted according to the collection time.

[0078] Step S430: merging multiple sub-files that are adjacent to each other in the target sorting and are both high-precision record files or regular record files.

[0079] Specifically, if there are adjacent sub-files that are both high-precision record files or both regular record files, as long as they are continuous and adjacent in the target sorting, they need to be merged, and no matter how many continuous parts are included, they are all regarded as merged into one.

[0080] Beneficial effect: the sub-files are sorted in the order of acquisition time, and the continuous and adjacent sub-files of the same type are merged, so the number of sub-files can be reduced, further reducing the storage burden.

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

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

[0083] Specifically, the data obtained by the remote calibration device can be projected directly on the vehicle's central control screen using the vehicle's central control display. In the past, data could only be downloaded to the engineer's laptop for analysis, which was a waste of the vehicle's central control screen. The vehicle's central control display can support online display requests from remote devices. During the experiment, the calibration measurement signal is directly displayed on the vehicle's central control screen in real time, making full use of the vehicle's central control screen to support experimental testing.

[0084] Technical effect: By displaying the recorded data on the vehicle-side display screen for real-time analysis by users, users can make real-time analysis while making full use of vehicle-side equipment, avoiding waste and improving analysis efficiency.

[0085] In some embodiments, the data recorded by the remote calibration device can support 5G / WIFI cloud access, and local engineers can analyze mark data and ordinary data by accessing the network, which is convenient for engineers to locate problem data and conduct analysis as soon as possible.

[0086] Figure 6 The schematic diagram of the structure of the embodiment of the recording device for remote calibration data of the present application is shown. 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 used to determine the start and end time of the high-precision recording according to the receiving time corresponding to the high-precision recording instruction in response to the high-precision recording instruction during the data recording process; wherein the data recording process also includes conventional 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 used to perform high-precision recording of the data collected at each moment between the start moment and the end moment; wherein the types of high-precision data recorded by the high-precision recording are more than the types of 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 effect: By responding to the high-precision recording instruction during the data recording process, the start and end times of the high-precision recording are determined according to the corresponding receiving time of the high-precision recording; and the data collected at each time between the start and end times are recorded with high precision. Thus, the time when the target data occurs is recorded with high precision during the data recording process, and the problem can be quickly analyzed based on the recorded high-precision data, thereby saving the manpower cost and time cost of engineers flipping through the data, and greatly improving the efficiency of problem analysis.
