[0054] Obviously, the described embodiments are only part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0057] Please refer to Figure 1 , which shows a flow chart of a data detection method provided by an embodiment of the present application. The data detection method can be applied to a data detection platform, and specifically may include:

[0058] Step 101 : In response to a selection operation on a detection control, chassis signal data of a vehicle is acquired, where the chassis signal data is collected based on a multi-channel bus access device.

[0059] Step 102: parse and process the chassis signal data to obtain first signal data and second signal data in the chassis signal data.

[0060] Step 103: Determine first fault information based on the first signal data.

[0061] Step 104: Based on a preset configuration file, detect and process the second signal data to obtain second fault information of the second signal data.

[0062] Step 105: output the first signal data, the second signal data, the first fault information and the second fault information to the detection result interface, and highlight the first fault information and the second fault information.

[0063] It should be noted that the chassis signal data may include first signal data and second signal data. The first signal data may be chassis signal data after detection and processing by the vehicle-mounted controller. The first signal data may be chassis signal data having a fault detection result obtained after fault detection processing by the vehicle-mounted controller. The second signal data may be original chassis signal data.

[0064] It should be noted that the chassis signal data may also include but is not limited to power signal data, sensor signal data, controller signal data, status signal data, electrical signal data, temperature signal data, tire pressure signal data, etc.

[0065] It should be noted that the detection control may be a control in the display interface of the data detection platform. The detection result interface may be an interface in the display interface of the data detection platform.

[0066] In this way, the chassis signal data of the vehicle can be collected through the multi-channel bus access device, the chassis signal data can be parsed and detected, the chassis fault information can be automatically and timely output, the chassis signal data and chassis fault information can be highlighted, and the automatic detection of a large amount of chassis signal data can be realized, and the presentation effect of chassis signal data and related fault information can be optimized, thereby improving the reliability of vehicle chassis signal data quality detection and user experience.

[0067] Optionally, in a possible implementation of this embodiment, in step 101, chassis signal data collected based on the unified diagnostic service UDS protocol and the multi-channel bus access device can be obtained, and then the chassis signal data can be used as the chassis signal data of the vehicle.

[0068] In this implementation, the detection control may include controls for different detection scenarios. The detection scenario may include an electrical detection scenario and a charging detection scenario.

[0069] In a specific implementation process of this implementation method, in response to the selection operation of the detection control of the electrical inspection scene, the chassis signal data collected based on the unified diagnostic service UDS protocol and the multi-channel bus access device can be obtained, and then the chassis signal data can be used as the chassis signal data of the vehicle.

[0070] In another specific implementation process of this implementation method, in response to the selection operation of the detection control of the charging detection scene, the chassis signal data collected based on the unified diagnostic service UDS protocol and the multi-bus access device can be obtained, and then the chassis signal data can be used as the chassis signal data of the vehicle.

[0071] It is understandable that the chassis signal data collected by the multi-channel bus access device may also be combined with other existing collection methods, and the specific implementation method may not be limited.

[0072] In this way, the chassis signal data collected by the UDS protocol and the multi-channel bus access device can realize the collection of a large amount of chassis signal data, ensuring the efficiency and real-time performance of chassis signal data collection.

[0073] Optionally, in a possible implementation of the present embodiment, in step 104, the detection item corresponding to the second signal data can be determined based on a preset configuration file, and based on the detection item corresponding to the second signal data, a preset initial value of each detection sub-item in the detection item is obtained; in response to the second signal data not matching the preset initial value, it is determined that a fault exists in the detection sub-item; based on the faulty detection sub-item, second fault information of the second signal data is obtained.

[0074] In this implementation, the preset configuration file includes at least one detection item for detecting and processing chassis signal data. The detection item may include at least one detection sub-item.

[0075] Here, the preset initial value may be obtained from a preset DBC file. The second signal data may include the initial value of the signal data.

[0076] Exemplarily, for any detection sub-item, when the initial value of the signal data does not match the preset initial value of the detection sub-item, it can be determined that the second signal data of the detection sub-item is a fault value and the detection sub-item is faulty, and then based on the faulty detection sub-item, the second fault information of the second signal data can be obtained.

[0077] For example, the detection item is the battery management system status detection, and the detection sub-item is the accumulated current detection of the battery pack. The initial value of the current signal data in the collected second signal data to be detected can be used. If it does not match, it can be determined that there is a fault in the detection sub-item, and the second fault information of the second signal data can be obtained.

[0078] In a specific implementation process of this implementation method, it is also possible to obtain a preset normal range of each detection sub-item in the detection item based on the detection item corresponding to the second signal data, and then, in response to the second signal data being not within the preset normal range, determine that the detection sub-item has a fault, and obtain second fault information of the second signal data based on the faulty detection sub-item.

[0079] Here, the preset normal range may also be obtained from a preset DBC file.

[0080] Exemplarily, for any detection sub-item, when the second signal data is not within the preset normal range, it can be determined that the signal data of the detection sub-item is a fault value and the detection sub-item has a fault, and then based on the faulty detection sub-item, the second fault information of the second signal data can be obtained.

[0081] For example, the detection item is the battery management system status detection, and the detection sub-item is the insulation status detection. It can be determined whether the electrical signal data in the collected second signal data to be detected is within the preset normal range. If not, it can be determined that there is a fault in the detection sub-item and the second fault information of the second signal data can be obtained.

[0082] It should be noted that the specific implementation process provided in this implementation can be combined with the multiple specific implementation processes provided in the aforementioned implementation to implement the data detection method of this embodiment. For detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0083] Optionally, in a possible implementation of the present embodiment, in step 102, the association relationship between the first signal data and the detection item can be determined based on the preset configuration file, and then based on the first signal data and the association relationship, the fault information of the detection item can be obtained, and the fault information of the detection item can be determined as the first fault information.

[0084] In this implementation, the first signal data may include fault information obtained by detecting and processing the original chassis signal data through the vehicle-mounted controller, that is, the fault detection result corresponding to the vehicle-mounted controller.

[0085] In a specific implementation process of this implementation method, after determining the association relationship between the first signal data and the detection item, the fault information of the detection item can be determined based on the association relationship and the fault detection result in the first signal data, and then the first fault information can be obtained.

[0086] For example, the detection item is rear axle microcontroller unit (MCU) fault detection. If the fault detection result in the first signal data includes a rear axle MCU phase-to-phase short circuit fault, it can be determined that the fault information of the detection item includes a rear axle MCU phase-to-phase short circuit fault, and the first fault information includes a rear axle MCU phase-to-phase short circuit fault.

[0087] In another specific implementation process of this implementation manner, the first fault information may be obtained directly based on the fault information in the first signal data.

[0088] For example, the fault information in the first signal data is that the rear bridge MCU discharge timed out, and the first fault information may be that the rear bridge MCU discharge timed out, that is, the signal timed out.

[0089] Optionally, in a possible implementation of the present embodiment, further, in response to a selection operation on a software version detection control, version information of the chassis software of the vehicle can be obtained, and then the version information of the chassis software can be detected and processed to determine whether the version information of the chassis software matches the version information of the target software; in response to the version information of the chassis software not matching the version information of the target software, third fault information is obtained and the third fault information is highlighted; based on the version information of the target software, the chassis software is updated.

[0090] In a specific implementation process of this implementation method, the version information of the target software in the cloud can be obtained based on Over-the-Air Technology (OTA), and the chassis software can be updated based on the version information of the target software.

[0091] It should be noted that the specific implementation process provided in this implementation can be combined with the multiple specific implementation processes provided in the aforementioned implementation to implement the data detection method of this embodiment. For detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0092] Optionally, in a possible implementation of the present embodiment, in step 105, the first signal data, the second signal data, the first fault information and the second fault information may also be visualized, and the results of the visualization processing may be output to the detection result interface for display.

[0093] Optionally, in a possible implementation of the present embodiment, further, in response to the detection result of the chassis signal data not including fault information, the chassis signal data and the normal information of the detection result of the chassis signal data can be output to the detection result interface, i.e., displayed on the detection result interface.

[0094] In an implementation, the fault information may include, but is not limited to, a signal acquisition timeout, a signal initial value being a fault value, and a signal value not being within a preset normal range.

[0095] In a specific implementation process of this implementation, different types of fault information may be highlighted using different highlight colors.

[0096] For example, the fault information of signal acquisition timeout is displayed with a red highlight mark, the fault information of the signal initial value being the fault value is displayed with a yellow highlight mark, and the fault information of the signal value not being within the preset normal range is displayed with a blue highlight mark.

[0097] It should be noted that the specific implementation process provided in this implementation can be combined with the multiple specific implementation processes provided in the aforementioned implementation to implement the data detection method of this embodiment. For detailed description, please refer to the relevant content in the aforementioned implementation, which will not be repeated here.

[0098] In order to better understand the method of the embodiment of the present application, the method of the embodiment of the present application is described below with reference to the accompanying drawings and specific application scenarios.

[0099] Figure 2 is a flow chart of a data detection method provided by another embodiment of the present application, such as Figure 2 In this embodiment, the data detection method can be applied to a data detection platform and may include:

[0100] Step 201 : In response to a selection operation on a detection control, chassis signal data of a vehicle is collected based on a multi-channel bus access device.

[0101] In this embodiment, the multi-channel bus access device is used to collect vehicle chassis CAN bus data, and the multi-channel bus access device can support simultaneous access of at least two CAN channels.

[0102] In this way, the multi-channel bus access device can ensure the real-time data transmission to ensure the normal function of the UDS.

[0103] In this embodiment, the multi-channel bus access device and the data detection platform constitute a data detection system.

[0104] Step 202: parse and process the chassis signal data to obtain controller detection result signal data and original signal data in the chassis signal data.

[0105] Step 203 : Determine fault information and normal information based on a preset configuration file, the controller detection result signal data in the chassis signal data, and the original signal data.

[0106] In this embodiment, the fault information may include but is not limited to a signal acquisition timeout, a signal initial value being a fault value, and a signal value not being within a preset normal range.

[0107] It is understandable that the controller detection result signal data may be the first signal data, and the controller detection result signal data includes the fault information detected by the controller. The controller detection result signal data may be directly collected to the data detection platform through a multi-channel bus access device. The original signal data may be the second signal data, that is, the original chassis signal data.

[0108] Step 204: Based on different color identifiers, highlight the fault information of the type corresponding to the color identifier on the detection result interface.

[0109] In this embodiment, at the same time, normal information can also be output and processed to be displayed on the detection result interface.

[0110] Step 205: Generate and store a detection report file based on the fault information.

[0111] In this embodiment, when starting the test, the tester user can select the configuration of different test scenarios to trigger the collection of chassis signal data. When the data parser of the data detection platform receives the chassis signal data, it will perform data analysis and detection processing on the chassis signal data according to the preset configuration file to obtain the result of the detection processing. The result of the detection processing may include normal information and fault information.

[0112] Here, the normal information may be normal data information in the detected chassis signal data, and the fault information may be fault data information in the detected chassis signal data.

[0113] In this embodiment, illustratively, when it is determined that a fault exists, the fault is reported to a front-line engineer, and at the same time, fault information of different fault types is distinguished by different colors on the detection result display interface.

[0114] Here, for each detection cycle, historical fault information can be recorded and a detection report can be generated for the detection personnel to analyze and determine whether the detection item has passed.

[0115] In this embodiment, when it is detected that the chassis software needs to be upgraded, the OTA function can be used to pull the target software version from the cloud, and then send the target software version to the vehicle chassis through the multi-channel bus access device and the CAN bus for software upgrade.

[0116] The solution in this embodiment can receive and send chassis signal data through the CAN network through a multi-channel bus access device, and can realize redundant links to ensure the stability of data collection to meet the needs of vehicle detection and data collection. In addition, data interaction can be carried out through the UDS protocol to ensure the real-time nature of data collection.

[0117] In addition, by adopting the solution in this embodiment, it is possible to realize automatic detection of a large number of chassis signal data, and to realize the persistent storage of the collected data.

[0118] In addition, by adopting the solution in this embodiment, the test results can be highlighted and the test engineer can be notified immediately, which makes it easier for the test engineer to detect and locate the problem.

[0119] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously.
