Description

Technical Field

[0001] The present application relates to the field of vehicle safety, and in particular to a whole vehicle function detection method, system, electronic equipment and storage medium. Background Art

[0002] As the development trend of automobiles moves towards electrification and intelligence, the concept of software-defined cars has been deeply rooted in people's minds. Functional safety and information security have become the core issues of the automotive industry. This has not only promoted the progress of automotive electronic technology, but also made automotive electronic systems occupy an increasingly large share in the cost structure of the entire vehicle and the after-sales service link, especially the electronic control unit (ECU) and vehicle system functions are the core focus elements. At present, before a new car leaves the factory, a comprehensive electronic system inspection is usually carried out on the vehicle to ensure that the ECU status and system functions of each vehicle meet the established standards. However, in the field of automotive after-sales service, although there are auxiliary means such as after-sales diagnostic tools and maintenance guides, in the general after-sales service process, maintenance personnel mainly rely on personal experience and subjective judgment to carry out vehicle inspections, which not only increases the risk of operational errors, but also leads to inconsistency in test results. When vehicles of different brands and models face various maintenance needs, the current inspection lacks a unified test process and evaluation criteria. In this case, it is difficult to make an accurate assessment of the overall condition of the vehicle, and it is easy to ignore potential hidden dangers and fail to fundamentally solve the problem, thereby increasing the possibility of repeated repairs in the short term, affecting customer satisfaction and after-sales service efficiency.

This method reduces the degree of manual participation, reduces the possibility of human error, improves the quality of after-sales service detection, and enhances customer trust.

[0031] Figure 2 is a flow chart of a vehicle function detection method shown in an exemplary embodiment of the present application. The vehicle function detection method can be Figure 1 The implementation environment may be implemented in other implementation environments, and the above implementation environments are not specifically limited here. Figure 2 As shown, the flowchart of the vehicle function detection method includes at least steps S210 to S240, which are described in detail as follows:

[0032] In step S210, a detection communication connection with the vehicle to be detected is established, and identity information of the vehicle to be detected is obtained based on the detection communication connection.

[0033] In one embodiment of the present application, a preferred implementation of the present application is to reuse the functions of the existing after-sales diagnostic system, expand, develop and implement the detection process of the present application on the existing after-sales diagnostic system, wherein the after-sales diagnostic system includes a diagnostic cloud and a diagnostic client. The execution subject of the present application is a computer device with a diagnostic client installed, wherein the diagnostic cloud is connected to the associated business system on the one hand, such as the vehicle archive system (obtaining vehicle information), the automotive cloud platform (obtaining Tbox remote communication data), the dealer management work order system, the software management platform (obtaining ECU part number and software and hardware information and software package), maintenance manuals and maintenance cases, etc., and on the other hand, it manages the diagnostic database (diagnostic definition and description of each vehicle model ECU), the standardized detection database (detection items of each vehicle model), the detection report, the diagnostic log, etc.

[0034] In one embodiment of the present application, the diagnostic client is an application installed on a computer device, which, on the one hand, implements conventional after-sales diagnostic functions, such as reading ECU version information, reading ECU fault information, reading ECU dynamic data stream, actuator testing, software flashing, component replacement, learning calibration, special functions, diagnostic log generation, etc., and on the other hand, implements standardized vehicle detection functions, including ECU status detection, system function static detection, system function dynamic detection, detection report generation, etc.

[0035] In the embodiment of the present application, the detection communication connection with the vehicle to be detected is that the computer device with the diagnostic client program installed is connected to the vehicle OBD port through the diagnostic VCI device or the OBD transfer cable. OBD (On-Board Diagnostics) is an electronic system used to monitor the working status of the engine and other related systems in modern cars. The OBD system was originally designed to meet the requirements of emission control, but it has now been widely used to monitor the health status and performance indicators of vehicles. VCI (Vehicle Communication Interface) equipment is a hardware device specially designed to communicate with the vehicle electronic system. This device is usually used in the process of automobile maintenance and diagnosis. It allows technicians to connect to the OBD port of the vehicle and read the vehicle's data stream, fault code and other information through special software. The device of the standardized detection process of the vehicle's entire vehicle status and system functions uses the after-sales diagnostic system tools commonly used in service stations for function expansion, avoiding the problem of additional tool development and procurement, and the automation and guided operation will not bring the problem of difficulty in using the tool.

[0036] In step S220, a standard information request is sent to the server based on the identity information, and vehicle standard information corresponding to the identity information fed back by the server is received.

[0037] In one embodiment of the present application, after a standard information request is sent to the server based on the identity information, the server receives the standard information request and queries the vehicle information results in the vehicle archive based on the identity information in the request. If the vehicle information exists, the standardized inspection database in the server is automatically called to feedback the vehicle standard information; if the vehicle model information does not exist, relevant technical personnel are required to manually select similar or identical vehicle standard information based on the vehicle model information for sending.

[0038] In step S230, in response to the vehicle function detection request, a first function detection step and a second function detection step are respectively performed to obtain a first detection result and a second detection result.

[0039] In one embodiment of the present application, the first function detection step includes detection steps of multiple vehicle electronic control units, and the second function detection step includes multiple vehicle system control detection steps.

[0040] In one embodiment of the present application, executing the first function detection step includes acquiring characteristic information of the vehicle electronic control unit in the vehicle to be detected based on the detection communication connection, performing the electronic control unit basic detection step, the electronic control unit fault detection step and the electronic control unit node detection step respectively according to the corresponding information types in the characteristic information, obtaining the basic detection result, the fault information detection result and the node detection result, and generating the first detection result according to the basic detection result, the fault information detection result and the node detection result. Among them, the characteristic information includes the number of vehicle electronic control units, the vehicle software version number, the version information of each controller, the fault information, and the key component information.

[0041] In one embodiment of the present application, the above-mentioned electronic control unit basic detection step includes: obtaining an electronic control unit missing detection result based on the difference between the number of vehicle electronic control units and the number of standard electronic control units in the vehicle standard information; obtaining a vehicle software version detection result based on the consistency status of the vehicle software version number and the latest software version number in the vehicle standard information; obtaining controller version detection information of each controller based on the consistency status of the version information of each controller and the latest version information of the controller in the vehicle standard information; and determining the electronic control unit missing detection result, the vehicle software version detection result and the controller version detection information of each controller as the basic detection result. Among them, the version information of each controller includes the part number information and hardware version information of the electronic control unit, so the controller version detection information further includes the electronic control unit part number detection information and the electronic control unit hardware version detection information.

[0042] In one embodiment of the present application, the above-mentioned electronic control unit fault detection step includes detecting the existence status of a fault record entry in the fault information, and if a fault record entry exists, generating a fault information detection result according to the fault record entry. Specifically, it is to read whether the electronic control unit fault information includes a DTC fault code, a freeze frame and a snapshot data, wherein the DTC fault code, the freeze frame and the snapshot data are consistent with the above-mentioned fault record entry. DTC (Diagnostic Trouble Code) is a coding standard used for automobiles and other complex mechanical systems to identify problems that occur in the system. When one or more systems of the vehicle detect abnormal operation, the on-board computer (ECU, Engine Control Unit, engine control unit or other control module) will generate and store a DTC code. These codes help technicians quickly identify the problem and make appropriate repairs.

[0043] In one embodiment of the present application, the above-mentioned electronic control unit node detection step includes obtaining key node data identifier information and key node communication information, and the key component information includes key node data identifier information and key node communication information; determining the identifier information detection result according to the key node data identifier information and the standard identifier information of the key node in the vehicle standard information; determining the communication detection result according to the key node communication information and the standard communication information of the key node in the vehicle standard information; determining the identifier information detection result and the communication detection result as the node detection result. Among them, the key node data identifier information includes but is not limited to low-voltage power supply voltage and current, high-voltage power supply voltage and current, accelerator pedal opening, sensor voltage, Ethernet domain control device certificate filling status, Ethernet domain control device certificate trust ring status, key controller key filling status, vehicle local data mirroring closed status and diagnostic agent open status. Key node communication information includes but is not limited to BMS fault level, brake fluid level alarm status, drive motor temperature alarm status and tire pressure sensor pressure alarm status, etc. It should be noted that due to the requirements of automobile information security, the OBD interface does not open vehicle communication data, so it is necessary to obtain the communication data uploaded by the Tbox in the vehicle to be tested through the server.

[0044] In one embodiment of the present application, the second function detection step includes determining a target detection item according to vehicle standard information, the target detection item includes a static instruction detection item and a dynamic guidance detection item, generating a corresponding detection instruction for the static instruction detection item, controlling the vehicle to perform static instruction detection based on the detection instruction, receiving instruction execution feedback information of the detection instruction, and determining the execution feedback information as a static instruction detection result; calling preset guidance operation information according to the dynamic guidance detection item and displaying it on the vehicle computer, receiving guidance execution feedback information fed back by the vehicle, and determining the guidance execution feedback information as a dynamic guidance detection result. A second detection result is generated according to the static instruction detection result and the dynamic guidance detection result.

[0045] Among them, static command detection includes tests such as window lifting and lowering, air conditioning opening and closing, and light opening and closing. Dynamic guidance detection can also include static guidance and dynamic guidance. Static guidance detection includes but is not limited to guiding relevant technicians through voice prompts to perform tests such as the brake light turning on after the brake pedal is pressed. Dynamic guidance includes but is not limited to guiding relevant technicians through voice prompts to shift gears and drive, and to detect diagnostic data such as gear status, vehicle speed status, engine speed, and drive motor torque status during driving.

[0046] In step S240, the vehicle standard information is compared with the first test result and the second test result to obtain test standard comparison information, and a test rating is performed based on the test standard comparison information to obtain a vehicle function test rating result.

[0047] In one embodiment of the present application, performing inspection rating based on inspection standard comparison information includes determining the inspection results of each abnormal inspection item in the inspection standard comparison information and the abnormal deviation degree of the corresponding information in the vehicle standard information, determining a first weight coefficient for each inspection item based on the abnormal deviation degree, determining a second weight coefficient for each inspection item according to preset vehicle safety weight ranking information, scoring each inspection item according to the first weight coefficient to obtain a score for each inspection item, and determining a total inspection score based on the second weight coefficient and the score of each inspection item, so as to determine the vehicle function inspection rating result according to the total inspection score and preset rating rules.

[0048] In one embodiment of the present application, after obtaining the whole vehicle function inspection rating result, a whole vehicle function inspection information list is generated based on the whole vehicle function inspection rating result and the inspection standard comparison information, the whole vehicle function inspection information list is sent to the server, and synchronized in the remote diagnosis system and the work order management system to perform vehicle maintenance based on the whole vehicle function inspection information list.

[0049] See also Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a specific vehicle information automatic identification process shown in an exemplary embodiment of the present application. Figure 3 As shown, in a specific embodiment of the present application, after connecting the vehicle, it is determined whether the connection information is a VCI device or an OBD network cable. It should be noted that this specific vehicle information automatic identification process is consistent with the implementation process of step S210 and step S220 in the above method embodiment.

[0050] In a specific embodiment of the present application, if it is recognized that the vehicle is connected through the diagnostic VCI device, the OBD access device is first verified to be online through the OBD pin. If it is online, a functional addressing request for OBD diagnosis is sent to the vehicle to read the vehicle VIN. If more than 2 / 3 of the controllers reply with the same valid VIN value, it is treated as the VIN of the vehicle; otherwise, the user is reminded to manually enter the vehicle VIN. VIN (Vehicle Identification Number) is a unique identification code for each car, similar to the vehicle's "ID number". VIN consists of 17 characters (letters and numbers), each of which has a specific meaning and is used to identify important information such as the manufacturer, model year, and production plant of the vehicle.

[0051] In a specific embodiment of the present application, if it is recognized that the vehicle is connected via an OBD to RJ45 network cable, the OBD access device of the after-sales diagnostic system is verified to be online through the OBD pin, and then a DoIP UDS diagnostic function addressing request is sent to the vehicle to read the vehicle VIN. If more than 2 / 3 of the controllers reply with the same valid VIN value, it is processed as the VIN of the vehicle; otherwise, the user is reminded to manually enter the vehicle VIN. DoIP (Diagnostics over Internet Protocol) is a communication protocol for automotive diagnosis, which allows efficient data transmission through an Ethernet interface, especially in combination with the UDS (Unified Diagnostic Services) protocol during the diagnosis and programming process to perform various diagnostic tasks.

[0052] In a specific embodiment of the present application, the specific information of the VIN in the vehicle archive system, such as model, year, optional package, configuration, ECU, etc., is automatically queried, judged and displayed; if no information is found, the user is reminded to manually select the model. The standardized test data of the model item of the tested vehicle is automatically called from the diagnostic cloud.

[0053] See also Figure 4 , Figure 4 FIG. 1 is a schematic diagram of a specific vehicle ECU state standardization detection process shown in an exemplary embodiment of the present application. Figure 4As shown, in a specific embodiment of the present application, for each different vehicle model item, a different vehicle ECU state standardization detection process is executed, which is consistent with the first function detection step in the above method embodiment.

[0054] In a specific embodiment of the present application, the ECU basic information diagnostic data is read, the vehicle software version number, and the controller version information (part number and software and hardware version) are read, and the corresponding information such as the control device number, software and hardware version in the latest vehicle software version number in the software management platform is compared. If there is inconsistency, in addition to automatically displaying abnormalities (including ECU quantity problems, part number problems and hardware version problems) and judging that the test has not passed, you can choose to automatically upgrade to the latest version of the ECU software package on the software management platform with one click. If you choose to upgrade with one click, return to the information reading step to re-diagnose. If you do not choose to upgrade with one click, it is judged that the test has not passed. If it is consistent, the test passes.

[0055] In a specific embodiment of the present application, the ECU fault information diagnostic data is read, and the fault information of the controller is read, including fault codes, freeze frames and snapshot data. If there is an abnormality, in addition to automatically displaying the abnormality, you can click on the fault information to automatically jump to the interface of the maintenance manual or maintenance plan, and determine that the test has failed. If there is no DTC fault information, the test has passed.

[0056] In a specific embodiment of the present application, ECU special data is read for diagnosis, including reading DID (data identifier) ​​diagnostic data in ECU and obtaining remote communication data from the car cloud platform. When reading the controller-related DID value, in addition to reading common data such as low-voltage power supply voltage and current, high-voltage power supply voltage and current, accelerator pedal opening and sensor voltage value, it is also necessary to read data closely related to automobile information security, such as the device certificate filling status and trust ring status of Ethernet domain controller, the key filling status of key controller, the vehicle local data mirroring closed status and the diagnostic agent open status, etc. If there is an abnormality, in addition to automatically displaying the abnormality, you can click on the fault information to automatically jump to the maintenance manual or maintenance plan interface. It should be noted that due to the requirements of automobile information security, the OBD interface usually does not open vehicle communication data, because it is necessary to obtain the communication data uploaded by the car cloud platform from the vehicle-side Tbox through the diagnostic cloud, and select specific data for monitoring and judgment: such as BMS fault level, brake fluid level alarm status, drive motor temperature alarm status, tire pressure sensor pressure alarm status, etc.

[0057] See also Figure 5 , Figure 5 FIG. 1 is a schematic diagram of a specific system function standardization detection process shown in an exemplary embodiment of the present application. Figure 5As shown, in a specific embodiment of the present application, the above-mentioned specific system function standardization detection includes multiple test sequences, which can be specifically divided into static automatic execution, static guided and dynamic guided tests, and the execution method is consistent with the first function detection step in the above-mentioned method embodiment.

[0058] In a specific embodiment of the present application, during static automatic execution, for the IO control defined in the vehicle diagnostic database, according to the standardized detection execution sequence, functional testing can be performed by sending relevant instructions, such as: the body domain control VIU1 IO Control defines that the DID of the left front window lifting control is 0xA1B2, the number of bytes is 1, and the conversion relationship is 0x00:Default, 0x01:UP, 0X02:DOWN, then the execution sequence prompts "The left front window lifting function is about to be performed, please pay attention to your safety", and the diagnostic system automatically sends 2F A1 B2 03 02 to lower the left front window, and after 10 seconds, it sends 2F 53A1 B2 01 to raise the left front window, and after 10 seconds, it sends 2F A1 B2 0302 to lower the left front window. In this process, the left front window status diagnostic data in the data stream is read through the diagnosis, and the left front window status communication data uploaded by the vehicle cloud platform from the vehicle-side Tbox is obtained through the diagnosis cloud to compare and determine the results.

[0059] In a specific embodiment of the present application, static guidance is to guide the user to operate the commonly used vehicle input signal according to the standardized detection execution sequence. For example, the execution sequence prompts "Please step on the vehicle brake pedal and hold it", which requires the user to cooperate in performing the corresponding action. The diagnostic data of the brake pedal depression status and the brake light status in the data stream is read through the diagnosis, and the communication data of the brake pedal depression status and the brake light status uploaded by the vehicle-side Tbox by the vehicle cloud platform is obtained through the diagnosis cloud, and the results are automatically compared and judged.
