[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0036] The ECU is also known as the "vehicle computer" of the vehicle, and its purpose is to control the driving state of the vehicle and implement its various functions. Currently, multiple ECUs are installed in vehicles. When a new vehicle leaves the factory, functional configuration, VIN code writing, function learning, and related parameter writing operations need to be performed on each ECU system before it can be delivered to customers for use to ensure the normal operation of the vehicle functions. Currently, during the vehicle off - line stage, the diagnostic device needs to perform operations such as configuring each ECU of the vehicle and writing the VIN code. However, due to the inability to effectively verify the VIN to be written, there may be a problem that the VIN code to be written is inconsistent with the vehicle's own configuration. For this reason, the present application provides a vehicle identification number verification solution based on a diagnostic device, which can verify the vehicle identification number to be written during the vehicle off - line stage and avoid writing errors caused by the mismatch between the vehicle identification number and the vehicle configuration information.
[0037] See Figure 1 As shown, the embodiments of the present application disclose a vehicle identification number verification method based on a diagnostic device, including:
[0038] Step S11: Determine the engine management system corresponding to the current vehicle according to the vehicle configuration for vehicle assembly operations, and store the temporary vehicle identification code in a preset storage space in the engine management system during the vehicle assembly process.
[0039] In this embodiment, select the EMS (Engine Management System) engine corresponding to the vehicle according to the vehicle configuration. And store the temporary vehicle identification code in a preset storage space in the engine management system during the vehicle assembly process, so that the diagnostic device can read the temporary vehicle identification code from the preset storage space. Wherein, the temporary vehicle identification code is a vehicle identification code composed of a world manufacturer identification code and a vehicle characteristic code generated based on the vehicle configuration, and is used to compare with the vehicle identification code to be written to verify the consistency between the vehicle configuration and the vehicle identification code to be written.
[0040] See Figure 2 As shown, the vehicle identification code to be written is composed of a world manufacturer identification code, a vehicle characteristic code, and a vehicle indication code. The VIN code consists of 17 characters (including English letters and numbers), commonly known as the seventeen-digit code. It is a set of characters assigned by the manufacturer to identify a vehicle, containing information such as the vehicle's manufacturer, year, model, body type and code, engine code, and assembly location, etc. The VIN code is the unique identifier for each vehicle, which will not be repeated or modified. The composition of the VIN code has certain rules, and different characters represent different meanings, specifically as follows: The 1st - 3rd digits are the world manufacturer identification code (WMI), used to identify the vehicle's manufacturer, brand, and type information. The 1st digit represents the country / region of origin, the 2nd digit represents the vehicle manufacturer, and the 3rd digit represents the conventional vehicle type; The 4th - 8th digits are the vehicle characteristic description part (VDS), used to describe the general characteristics of the vehicle, such as vehicle type, series, body type, engine type, rated gross weight, etc.; The 9th digit is the check digit code, used to check whether the VIN is filled in correctly; The 10th - 17th digits are the vehicle indication part (VIS), which are primary characters specified to distinguish different vehicles. Among them, the 10th digit represents the manufacturing year, the 11th digit represents the final assembly plant code, and the 12th - 17th digits represent the production sequence number.
[0041] Step S12: When the vehicle assembly operation is completed, compare the vehicle identification code to be written with the temporary vehicle identification code to obtain the corresponding comparison result.
[0042] In this embodiment, the vehicle identification code to be written is verified by comparing the same structures of the vehicle identification code to be written and the temporary vehicle identification code. Since there are the same world manufacturer identification code and vehicle characteristic code structures in the temporary vehicle identification code and the vehicle identification code to be written, and the world manufacturer identification code and vehicle characteristic code are composed of fixed rules and have a stable data structure, which can effectively retain vehicle configuration information. Therefore, in a specific embodiment, the vehicle identification code to be written is verified by comparing the world manufacturer identification code and vehicle characteristic code in the vehicle identification code to be written with the world manufacturer identification code and vehicle characteristic code in the temporary vehicle identification code. Specifically, comparing the vehicle identification code to be written with the temporary vehicle identification code to obtain a corresponding comparison result may include: reading the world manufacturer identification code and vehicle characteristic code in the temporary vehicle identification code; comparing the world manufacturer identification code and vehicle characteristic code in the vehicle identification code to be written with the world manufacturer identification code and vehicle characteristic code in the temporary vehicle identification code to obtain a corresponding comparison result.
[0043] Step S13: Determine whether the vehicle identification code to be written is consistent with the vehicle configuration of the current vehicle according to the comparison result, to obtain a corresponding determination result, and perform a corresponding processing operation on the current vehicle according to the determination result to complete the vehicle off-line function detection process.
[0044] In this embodiment, it is verified whether the vehicle identification code to be written is correct according to the comparison result of the world manufacturer identification code and vehicle characteristic code in the vehicle identification code to be written and the world manufacturer identification code and vehicle characteristic code in the temporary vehicle identification code. Specifically, determining whether the vehicle identification code to be written is consistent with the vehicle configuration of the current vehicle according to the comparison result to obtain a corresponding determination result may include: if the world manufacturer identification code and vehicle characteristic code in the vehicle identification code to be written are both consistent with the world manufacturer identification code and vehicle characteristic code in the temporary vehicle identification code, a determination result indicating that the vehicle identification code to be written is consistent with the vehicle configuration of the current vehicle is obtained; otherwise, a determination result indicating that the vehicle identification code to be written is inconsistent with the vehicle configuration of the current vehicle is obtained.
[0045] It should be noted that after the vehicle is assembled, operations such as writing configurations, writing VIN, clearing and reading fault codes need to be performed on each ECU of the vehicle. Only after the vehicle passes the inspection can it roll off the production line normally. Therefore, different vehicle processing procedures also need to be determined according to the different verification results. Specifically, the step of performing corresponding processing operations on the current vehicle according to the judgment result to complete the vehicle roll-off function detection process may include: if the judgment result indicates that the vehicle identification code to be written is consistent with the vehicle configuration of the current vehicle, perform the vehicle identification code writing operation to complete the vehicle roll-off function detection process; if the judgment result indicates that the vehicle identification code to be written is inconsistent with the vehicle configuration of the current vehicle, move the current vehicle to the maintenance area for maintenance. Among them, the vehicle identification code writing operation is an operation of writing the vehicle identification code to be written into each electronic control unit of the current vehicle through the diagnostic device.
[0046] As can be seen from the above, in this application, the temporary vehicle identification code is stored in the preset storage space according to the vehicle configuration information, and the temporary vehicle identification code is read when the vehicle identification code needs to be written during the vehicle roll-off inspection process. The world manufacturer identification code and vehicle characteristic code in the vehicle identification code to be written are compared with the world manufacturer identification code and vehicle characteristic code in the temporary vehicle identification code to verify whether the vehicle configuration information matches the vehicle identification code to be written, so as to be able to verify the vehicle identification code to be written during the vehicle roll-off stage and avoid writing errors caused by the mismatch between the vehicle identification code and the vehicle configuration information.
[0047] Furthermore, an embodiment of the present application discloses a specific method for verifying a vehicle identification code based on a diagnostic device, including:
[0048] In this embodiment, the corresponding EMS engine of the vehicle is selected according to the vehicle configuration, and when the EMS engine is assembled in the vehicle, a temporary VIN code including the correct WMI and VDS is pre-stored in the VIN code storage area of the EMS engine. That is, the WMI and VDS information matching the vehicle configuration is recorded by pre-storing the temporary VIN code, so as to facilitate the subsequent verification of the VIN code to be written.
[0049] In this embodiment, when the vehicle ECU needs to write the VIN code, the diagnostic device first reads the temporary VIN code information of the EMS engine. The diagnostic device compares the WMI and VDS information parts of the read VIN code with the WMI and VDS information parts of the VIN code to be written. Among them, if the comparison result of the diagnostic device is consistent, the VIN code writing operation is performed. If the comparison result of the diagnostic device is inconsistent, it is prompted that the VIN code to be written does not match the vehicle, the vehicle cannot roll off the production line, and the vehicle enters the area to be repaired for problem confirmation and repair. Replace the vehicle and repeat the above operations to complete the vehicle roll-off function detection work.
[0050] As can be seen from the above, in the embodiment of the present application, when assembling the ECU controller of the vehicle, the temporary VIN code is preset to the VIN storage area of the ECU controller according to the vehicle configuration information and stored. When the VIN code needs to be written to the ECU controller after the vehicle rolls off the production line, the WMI and VDS information of the VIN code already stored in the vehicle ECU controller is first read and compared with the WMI and VDS information of the VIN code to be written. If they are consistent, the complete VIN code information is continued to be written. If they are inconsistent, it is prompted that the VIN code to be written does not match the vehicle, resulting in the vehicle being unable to roll off the production line normally. Through this method, the problem of incorrect writing of the VIN code can be effectively prevented, and whether the VIN code to be written matches can be verified through the vehicle configuration information. Thereby improving production efficiency and after-sales efficiency.
