[0045] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be 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 invention are shown in the accompanying drawings.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] Figure 1 This is a flow chart of a vehicle data processing method proposed in the present application. The method can be executed by a vehicle data processing device. The vehicle data processing device can be implemented in software and / or hardware form and can be integrated in a vehicle controller.

[0048] like Figure 1 As shown, the vehicle data processing method includes the following steps:

[0049] S110 . In response to receiving a data processing instruction, obtaining data to be processed of a target control unit and obtaining a first data parsing operator, wherein the data to be processed is communication data based on a target communication protocol.

[0050] The target communication protocol may be SOME / IP.

[0051] The data to be processed can be driving perception algorithm data, map message data, camera message data or radar message data. The data to be processed is communication data based on the target communication protocol, or encapsulated data, which is not readable. Therefore, it is necessary to parse the data to be processed to obtain readable target data so as to conduct relevant development and research through data analysis.

[0052] Optionally, the obtaining the first data parsing operator includes:

[0053] The first data parsing operator is read from a target storage location.

[0054] S120: Process the data to be processed according to the data processing instruction, and parse the data to be processed by the first data parsing operator to obtain real target data.

[0055] In some implementations, the data processing instruction includes a data recording instruction, and processing the data to be processed according to the data processing instruction includes:

[0056] Taking the topic as the division dimension, the to-be-processed data of different topics are respectively stored in recording files of different topics, and the version information of the first data parsing operator is respectively stored in each recording file.

[0057] The topic may represent the source of the data to be processed. For example, camera data, lidar data, and vehicle speed data may be stored as data of different topics in recording files of different topics.

[0058] The theme can also be determined according to different target control units. For example, the perception control unit, decision control unit, and execution control unit can be control units of different themes respectively, and the data to be processed from different control units can be stored in corresponding recording files respectively.

[0059] The purpose of storing the data to be processed of different topics in recording files of different topics based on the topic as the division dimension is to classify the data to be processed, so as to facilitate the subsequent re-injection and scene reproduction of the data of different topics, and then carry out research for different purposes. The purpose of storing the version information of the first data parsing operator in each recording file is to facilitate the verification of the version of the parsing operator when re-injecting data, so as to ensure that the re-injected data can be correctly parsed.

[0060] Correspondingly, the step of obtaining the data to be processed of the target control unit includes:

[0061] Receive the data to be processed output by the target control unit.

[0062] In some embodiments, the data processing instruction includes a data re-injection instruction, and the obtaining of the data to be processed of the target control unit includes: according to the subject to which the target control unit belongs, reading the data to be processed from a recording file matching the subject.

[0063] In some embodiments, before processing the data to be processed according to the data processing instruction, it also includes: reading version information of the second data analysis operator from the recording file, and comparing the read version information of the second data analysis operator with the version information of the first data analysis operator; in response to the version information of the second data analysis operator being different from the version information of the first data analysis operator, prompting target information; in response to the version information of the second data analysis operator being the same as the version information of the first data analysis operator, continuing to execute the operation of processing the data to be processed according to the data processing instruction (i.e., returning the data to be processed to the target control unit).

[0064] By adding version information verification to the parsing operator, it can be ensured that the injected data can be parsed correctly.

[0065] Furthermore, in order to improve the degree of visualization, the data to be processed may be further visualized and displayed through a visualization tool.

[0066] The vehicle data processing method disclosed in the embodiment of the present application automatically obtains the first data parsing operator when receiving a data processing instruction without the need for manual selection and acquisition, and then analyzes the data to be processed through the first data parsing operator to obtain real target data, thereby simplifying manual operations and improving the accuracy and efficiency of obtaining target data (i.e., readable data).

[0067] In some embodiments, reference is made to Figure 2 The system architecture diagram of data analysis and visualization shown includes a message communication party 10, a data collection and distribution module 11, a data analysis operator 12, a storage refill visualization module 13, a file system 14 and a visualization tool 15.

[0068] The SOME / IP message communication party 10 in the control unit uses SOME / IP messages for communication, which is self-describing data and depends on the data structure. If the data structure is modified, the corresponding message and parsing operator 12 will also have corresponding changes, otherwise the parsing will be incorrect or unavailable, which will affect the visualization. Changes in data structure, such as one more parameter in a data, such as Figure 3As shown in the figure, the original data structure includes two parameters, a and b, and the changed data structure includes three parameters, a, b and c. When the data structure is changed, if the parsing operator is not regenerated, the parsed data will not match the actual data, or the parsing process will report an error and the data cannot be parsed.

[0069] The data collection and distribution module 11 is used to receive SOME / IP messages and transmit them to the host computer, and is also used to receive SOME / IP messages fed back from the host computer and give them to each control unit.

[0070] The data parsing operator 12 is used to parse SOME / IP data and serialize the parsed data into proto visualization data. This parsing operator is matched with the data structure version in the control unit to solve the problem of compatibility of the re-injection version and the need for the host computer to manually load the parsing operator.

[0071] The storage re-injection visualization module 13 is used to store the recorded data in the file system 14, or read the data in the recorded file from the file system 14 and re-inject it to each control unit. It is also used to parse the SOME / IP data through the data parsing operator and transmit the parsed data to the visualization tool (such as foxglove) 15 for visualization display.

[0072] The file system 14 is used to store the parsed SOME / IP data and the version information of the parsing operator, and store them in the form of topics. The visualization tool (such as foxglove) 15 is used to visualize the parsed SOME / IP data, which supports the standard proto format.

[0073] In some optional embodiments, refer to Figure 4 The data recording process diagram shown in FIG. 1 includes the following steps:

[0074] S1. Start the host computer.

[0075] S2. Start data recording.

[0076] S3. Obtain data parsing operator.

[0077] S4. Receive the data output by the control unit, and write the data and the version information of the data parsing operator into the recording file at the same time.

[0078] S5. Use the data analysis operator to analyze and visualize the data output by the control unit to obtain target data.

[0079] S6. Send the target data to a visualization tool for display.

[0080] S7. End.

[0081] In some optional embodiments, refer to Figure 5 The schematic diagram of a data re-injection process shown in FIG. 1 specifically includes the following steps:

[0082] S51. Start the host computer.

[0083] S52, start data refill.

[0084] S53. Read the version information of the data parsing operator from the recording file.

[0085] S54, reading the first data parsing operator from the target storage location, and comparing the version information of the first data parsing operator with the version information read in S53, and if the two are consistent, continuing to perform subsequent operations.

[0086] If the version information of the first data parsing operator is consistent with the version information read in S53, it means that the data structure in the current control unit is consistent with the data structure in the recording file, and the control unit is compatible with the data in the recording file. Therefore, the data re-injection operation can be performed.

[0087] S55, reading data from the recording file and sending it to the control unit.

[0088] S56. Use the first data analysis operator to perform analysis and visualization processing on the data read from the recording file to obtain target data.

[0089] S57. Send the target data to a visualization tool for display.

[0090] S58, end.

[0091] The data analysis operator changes with the data structure of the data in the control unit. When the data structure is modified, the data analysis operator needs to be re-produced and synchronously integrated into the control unit. With this setting, the host computer can dynamically obtain the data analysis operator in the control unit in real time. In this way, there is no need to manually add data analysis operators to the host computer during recording and replay, and data analysis visualization can be performed, which reduces the difficulty of operation and avoids problems such as misoperation and version mismatch.

[0092] Whether it is SOME / IP or Protobuf message, it transmits payload data. When the payload data structure needs to change (for example, add a variable), the data parsing operator needs to be regenerated. Figure 6The data analysis operator generation diagram shown in FIG. 1 inputs the data structure to the SOME / IP deserialization code template and the Protobuf serialization code template to obtain the SOME / IP deserialization code cpp and the Protobuf serialization code cpp, which are finally compiled into binary files to obtain the data analysis operator. The process of using the data analysis operator to parse the data can be referred to as Figure 7 As shown, the SOME / IP message is deserialized by SOME / IP and serialized by Protobuf by the data parsing operator to obtain the parsed target data.

[0093] Figure 8 is a schematic diagram of the structure of a vehicle data processing device provided in an embodiment of the present application, which can be integrated into a vehicle controller. Figure 8 As shown, the device includes: an acquisition module 810 and a processing module 820.

[0094] Among them, the acquisition module 810 is used to obtain the data to be processed of the target control unit in response to receiving the data processing instruction, and to obtain the first data parsing operator, wherein the data to be processed is the communication data based on the target communication protocol; the processing module 820 is used to process the data to be processed according to the data processing instruction, and to parse the data to be processed through the first data parsing operator to obtain the real target data.

[0095] Furthermore, the acquisition module 810 is specifically configured to read the first data parsing operator from a target storage location.

[0096] Furthermore, the data processing instructions include data recording instructions, and the processing module 820 is specifically used to: store the to-be-processed data of different topics into recording files of different topics respectively based on the topic as the division dimension, and store the version information of the first data parsing operator into each recording file respectively.

[0097] Correspondingly, the acquisition module 810 is specifically used to receive the data to be processed output by the target control unit.

[0098] Furthermore, the data processing instructions include data re-injection instructions, and the acquisition module 810 is specifically used to: read the data to be processed from the recording file matching the subject to which the target control unit belongs; the processing module 820 is specifically used to: re-inject the data to be processed to the target control unit.

[0099] Furthermore, it also includes a verification module, which is used to read the version information of the second data analysis operator from the recording file, and compare the read version information of the second data analysis operator with the version information of the first data analysis operator; in response to the version information of the second data analysis operator being different from the version information of the first data analysis operator, a target information prompt is given; in response to the version information of the second data analysis operator being the same as the version information of the first data analysis operator, the operation of processing the data to be processed according to the data processing instruction is continued.

[0100] Furthermore, it also includes a display module, which is used to use the real target data as input of a visualization tool and to visualize the real target data through the visualization tool.

[0101] The vehicle data processing device disclosed in the embodiment of the present application automatically obtains the first data parsing operator when receiving a data processing instruction without the need for manual selection and acquisition, and then analyzes the data to be processed through the first data parsing operator to obtain real target data, thereby simplifying manual operations and improving the accuracy and efficiency of obtaining target data (i.e., readable data).
