For the sake of understanding, the following describes a specific flow of an embodiment of the automobile diagnostic method of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a method for diagnosing a vehicle according to the present invention, the method including:
101, acquiring a VIN code of a vehicle to be diagnosed when a first fault diagnosis instruction is received;
in this embodiment, the automobile diagnosis method is applied to diagnosis equipment, such as an automobile fault diagnosis instrument. The diagnostic equipment is provided with a plurality of different diagnostic software in advance, each diagnostic software corresponds to fault diagnosis of one vehicle type, and the diagnostic equipment can automatically call the corresponding vehicle type diagnostic software through a Vehicle Identification Number (VIN) of the current vehicle so as to perform fault diagnosis on the current vehicle.
Firstly, the diagnostic device receives a first fault diagnosis instruction, and the first fault diagnosis instruction can be directly triggered by a user on a display interface of the diagnostic device or triggered by an external intelligent terminal device (such as a mobile phone and a tablet computer) by the user and then is sent to the diagnostic device through the external intelligent terminal device. After receiving the first fault diagnosis instruction, the diagnostic equipment acquires the VIN code of the current vehicle to be diagnosed, wherein the VIN code consists of 17 letters or numbers and is the unique identifier of the vehicle.
Specifically, the step 101 may include: when a first fault diagnosis instruction is received, reading a VIN code of a vehicle to be diagnosed through an OBD interface of a vehicle-mounted diagnosis system; judging whether the VIN code is read successfully through the OBD interface; and when the VIN code is failed to be read through the OBD interface, acquiring the VIN code of the vehicle to be diagnosed, which is input by a user.
The diagnostic device can communicate with an Electronic Control Unit (ECU) of the vehicle through an On Board Diagnostics (OBD) interface, and further read the VIN code of the vehicle to be diagnosed from the ECU; and then, judging whether the VIN code is successfully read through the OBD interface, if the VIN code is successfully read through the OBD interface, directly using the read VIN code as the VIN code of the vehicle to be diagnosed, and if the VIN code is unsuccessfully read through the OBD interface, manually inputting the VIN code by a user, wherein the VIN code input by the user is used as the VIN code of the vehicle to be diagnosed by the diagnosis equipment.
102, reading a preset vehicle type identification position from the VIN code, and positioning a subfolder in a preset folder according to the vehicle type identification position, wherein the subfolder is named in advance according to the vehicle type identification position;
in this step, the diagnostic device reads a preset vehicle type identification position from the VIN code, and the vehicle type identification position is used for identifying different vehicle types, namely, the vehicle type identification position can be used for distinguishing different vehicle types. In the VIN code, the 1 st to 3 rd digits respectively represent the manufacturer, brand and type of the automobile, and the 4 th to 6 th digits respectively represent the type, series and body type of the automobile, so the 1 st to 3 th digits or the 4 th to 6 th digits of the VIN code can be selected as the distinguishing of different automobile types, namely, the diagnostic equipment can read the 1 st to 3 th digits or the 4 th to 6 th digits from the VIN code as the automobile type identification digits.
After the vehicle type identification position is read, the diagnosis device positions a subfolder in a preset folder according to the vehicle type identification position, and the subfolder is named according to the vehicle type identification position in advance.
Specifically, for example, a corresponding relationship between the vehicle type diagnostic software and the vehicle type identifier in the VIN code may be pre-established and stored in the VINCode folder, for example, the 1 st to 3 rd or the 4 th to 6 th of the VIN code may uniquely determine the vehicle type, and at this time, each subfolder in the VINCode folder may be named by the 1 st to 3 th or the 4 th to 6 th of the VIN code, so that the diagnostic device may retrieve the VINCode folder through the vehicle type identifier, and may locate the subfolder named by the vehicle type identifier.
103, reading a vehicle model software package pre-stored in the subfolder, and calling corresponding vehicle model diagnosis software according to the vehicle model software package, wherein the vehicle model diagnosis software is used for performing fault diagnosis on a certain preset vehicle model;
in this step, the diagnostic device reads a vehicle type software package pre-stored in the subfolder, and can call corresponding vehicle type diagnostic software according to the vehicle type software package, wherein the vehicle type diagnostic software is used for performing fault diagnosis on a certain preset vehicle type.
For example, the diagnostic device obtains the VIN code of the vehicle to be diagnosed as LHGGM2655B2106316, first obtains the GM2, which is the 4 th to 6 th bits of the vehicle model identifier, finds the subfolder named GM2 in the VINCode folder, then reads the vehicle model software package pre-stored in the GM2 folder, and calls corresponding vehicle model diagnostic software according to the vehicle model software package, so that the vehicle model diagnostic software can perform fault diagnosis on the vehicle to be diagnosed.
And 104, performing fault diagnosis on the vehicle to be diagnosed through the vehicle type diagnosis software, and generating a first fault diagnosis report.
In the step, the diagnosis device starts vehicle type diagnosis software corresponding to the vehicle type software package, carries out fault diagnosis on the vehicle to be diagnosed through the vehicle type diagnosis software, and generates a first fault diagnosis report.
Specifically, this step 104 may include: analyzing the VIN code through the vehicle type diagnosis software to obtain vehicle information of the vehicle to be diagnosed; determining a vehicle scanning path according to the vehicle information, and scanning systems under the vehicle scanning path to obtain fault code information of each system; and generating a first fault diagnosis report according to the fault code information.
The diagnostic equipment analyzes the VIN code through vehicle type diagnostic software to obtain vehicle information of the vehicle to be diagnosed, wherein the vehicle information comprises the year money and the vehicle type, then a vehicle scanning path is determined according to the vehicle information, and fault scanning is carried out on a system under the vehicle scanning path. For example, when the vehicle information is the model a in 2018, the system under the route of the model a in 2018 is subjected to fault scanning. The scanning system is all systems in the diagnostic range of the vehicle type diagnostic software, such as an engine system, a brake system, a gearbox system, an air bag system and the like. By scanning each system, the fault code information of each system can be obtained, and the fault code information can include a fault code number, fault code content and fault code state (such as current fault and intermittent fault).
And then, the diagnostic equipment generates a first fault diagnosis report according to the fault code information of each system, wherein the first fault diagnosis report can comprise the VIN code of the vehicle, the brand of the vehicle, the year, the model of the vehicle, the system scanning result and the report generation time, and the system scanning result comprises the system name and the corresponding fault code information.
In the embodiment, when a first fault diagnosis instruction is received, a VIN code of a vehicle to be diagnosed is obtained; reading a preset vehicle type identification bit from the VIN code, and positioning a subfolder in a preset folder according to the vehicle type identification bit, wherein the subfolder is named in advance according to the vehicle type identification bit; reading a vehicle model software package pre-stored in the subfolder, and calling corresponding vehicle model diagnosis software according to the vehicle model software package, wherein the vehicle model diagnosis software is used for performing fault diagnosis on a certain preset vehicle model; and carrying out fault diagnosis on the vehicle to be diagnosed through the vehicle type diagnosis software, and generating a first fault diagnosis report. By the method, the fault diagnosis of the vehicle is realized by automatically calling the corresponding vehicle type diagnosis software according to the VIN code, and compared with the prior art, vehicle maintenance personnel do not need to check a nameplate and manually select the vehicle type, so that the efficiency and the convenience of vehicle diagnosis are improved.
Referring to fig. 2, fig. 2 is a schematic flow chart of another embodiment of the automobile diagnosis method of the present invention. In this embodiment, the automobile diagnosis method includes:
the detailed implementation of the steps 201-204 is substantially the same as the steps 101-105 in the first embodiment, and will not be described herein again.
in this step, the diagnostic device receives a second fault diagnosis instruction, where the second fault diagnosis instruction may be triggered directly by a user on a display interface of the diagnostic device, or may be triggered by the user on an external intelligent terminal device (e.g., a mobile phone or a tablet computer), and then the second fault diagnosis instruction is sent to the diagnostic device through the external intelligent terminal device. And after receiving the first fault diagnosis instruction, the diagnosis equipment carries out fault diagnosis on the vehicle to be diagnosed according to the second fault diagnosis instruction and generates a second fault diagnosis report.
Specifically, the diagnostic device may first obtain the VIN code of the vehicle to be diagnosed according to the second fault diagnosis instruction, then calling corresponding vehicle type diagnosis software according to the VIN code, and analyzing the VIN code through the vehicle type diagnosis software to obtain the vehicle information of the vehicle to be diagnosed, the diagnosis device can inquire whether a first fault diagnosis report of the vehicle is stored in the diagnosis device according to the vehicle information, if so, a selection interface is displayed, the selection interface comprises a viewing button and a rescanning button, a user can view the first fault diagnosis report by clicking the viewing button, if the user clicks the rescanning button, the diagnosis equipment determines a vehicle scanning path according to the vehicle information of the vehicle to be diagnosed, and scanning the systems under the vehicle scanning path to obtain fault code information of each system, and then generating a second fault diagnosis report according to the fault code information.
Of course, the diagnostic device may also directly generate the second fault diagnosis report through the second fault diagnosis instruction without displaying the selection interface, and may be flexibly set in specific implementation.
Similar to the first fault diagnosis report, the second fault diagnosis report may also include a VIN code of the vehicle, a brand of the vehicle, a year, a model of the vehicle, a system scanning result, and report generation time, where the system scanning result includes a system name and corresponding fault code information.
And step 206, when a viewing instruction of the first fault diagnosis report and/or the second fault diagnosis report is received, displaying the first fault diagnosis report and/or the second fault diagnosis report.
After the diagnostic device generates the first fault diagnosis report and the second fault diagnosis report, the user may view the two diagnostic reports at any time, for example, if a viewing instruction of the first fault diagnosis report is received, the first fault diagnosis report is displayed, if a viewing instruction of the second fault diagnosis report is received, the second fault diagnosis report is displayed, and if an instruction for viewing the two fault diagnosis reports at the same time is received, the first fault diagnosis report and the second fault diagnosis report are displayed at the same time. This facilitates the user to view and compare diagnostic reports generated at different times.
Further, the first failure diagnosis instruction may be triggered before the vehicle to be diagnosed is repaired, and the second failure diagnosis instruction may be triggered after the vehicle to be diagnosed is repaired. Therefore, the generated first fault diagnosis report and the second fault diagnosis report are respectively a diagnosis report before vehicle maintenance and a diagnosis report after vehicle maintenance, and by comparing the two diagnosis reports, a user can conveniently verify whether the fault after vehicle maintenance is eliminated, so that the convenience of vehicle diagnosis is further improved.
Further, the first fault diagnosis instruction is triggered based on a preset first fault diagnosis control, and the second fault diagnosis instruction is triggered based on a preset second fault diagnosis control.
In specific implementation, two fault diagnosis controls can be preset on a diagnosis interface of the diagnosis device: the system comprises a Pre-Scan button and a Post-Scan button, wherein before the vehicle is maintained, a user clicks the Pre-Scan button to trigger a first fault diagnosis instruction, the diagnosis equipment generates a diagnosis report before the vehicle is maintained, after the vehicle is maintained, the user clicks the Post-Scan button to trigger a second fault diagnosis instruction, and the diagnosis equipment generates a diagnosis report after the vehicle is maintained. By setting two different fault diagnosis controls, a user can conveniently and visually select and generate a fault diagnosis report under a corresponding scene according to the current maintenance scene (before and after maintenance), and convenience in automobile diagnosis is further improved.
