[0043] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0044] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0045] See also Figure 1The embodiments of the present application provide an EOL process error prevention method, device, electronic device, and medium, which can be applied to servers and various EOL station detection equipment to prevent sequence jumps and disorder problems in the EOL process. The server can be an independent server or a server cluster composed of multiple servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence sampling point equipment. See Figure 1 , methods include:

[0046] S1: before the initialization phase, obtaining the exit result of the vehicle in the factory mode phase, and judging whether to skip the initialization phase and offline electrical inspection phase of the vehicle according to the exit result;

[0047] S2: before the off-line electrical inspection stage, obtaining the exit result of the vehicle in the factory mode exit stage, and judging whether to skip the off-line electrical inspection stage of the vehicle according to the exit result.

[0048] In the above embodiment, the sequence of the EOL process is the initialization phase, the offline electrical inspection initialization phase, and the factory mode exit initialization phase.

[0049] In the above implementation process, the exit result of the exit factory mode stage is obtained before the initialization stage and the exit factory mode stage. Based on the exit result, it can be known whether the vehicle has passed the exit factory mode stage, and then it is judged according to the exit result whether to skip the initialization stage and the offline electrical inspection stage of the vehicle, avoiding multiple initialization and offline inspection of the vehicle, and solving the problem of reverse process.

[0050] In some embodiments, the method further includes: before entering the factory mode stage, obtaining processing results of the initialization stage and the offline electrical inspection stage; and determining whether to enter the factory mode stage according to the processing results.

[0051] In the above implementation, before exiting the factory mode phase, the processing results of the initialization phase and the offline electrical inspection phase are obtained; based on the processing results, it is determined whether to enter the exit factory mode phase. Based on this implementation, it is possible to prevent the vehicle from directly entering the exit factory mode phase without completing the initialization phase and the offline electrical inspection phase, thus solving the problem of skipping processes.

[0052] In some embodiments, S1 includes: if the exit result is qualified, skipping the vehicle initialization phase and the off-line electrical inspection phase; S2 includes: if the exit result is qualified, skipping the vehicle off-line electrical inspection phase.

[0053] Exemplarily, after the offline electrical inspection station device obtains the result of the exit factory mode station from the server, the offline electrical inspection station device makes a judgment and gives a reminder. If the result of the exit factory mode station is "qualified", the offline electrical inspection station device interface displays a reminder "the vehicle has implemented the exit factory mode operation", and the device does not perform the offline electrical inspection operation. If the result of the exit factory mode station is "unqualified", the offline electrical inspection station device interface does not display the error-proofing reminder information, and the device normally performs the offline electrical inspection operation.

[0054] In the above implementation process, if the exit result is qualified, it means that the vehicle has completed the exit factory mode operation, and at this time, there is no need to perform the initialization stage or the offline electrical inspection stage.

[0055] Further, the method further comprises:

[0056] pre-storing the first identification information on the vehicle;

[0057] receiving, in the initialization stage, second identification information input by the worker according to the first identification information;

[0058] reading the first identification information from the ECU of the vehicle before the exit factory mode stage, obtaining the second identification information on the vehicle, and judging whether the first identification information and the second identification information match, if so, entering the exit factory mode stage of the vehicle.

[0059] In the above implementation process, the first identification information is pre-stored on the vehicle; the second identification information input by the worker according to the first identification information is received in the initialization stage; and the first identification information and the second identification information are matched in the subsequent stage, so that whether the worker inputs the second identification information into different vehicles can be judged according to the matching result, and if the first identification information and the second identification information match, the exit factory mode stage of the vehicle can be entered.

[0060] Further, the first identification information is stored in an information storage medium, and the information storage medium is placed on the vehicle.

[0061] receiving, in the initialization stage, second identification information input by the worker according to the first identification information, comprises:

[0062] obtaining the second identification information about the vehicle input by the worker, and storing the second identification information in the ECU of the vehicle.

[0063] In some embodiments, obtaining the second identification information about the vehicle input by the worker and storing the second identification information on the vehicle, comprises:

[0064] obtaining the second identification information about the vehicle input by the worker, and storing the second identification information in the vehicle.

[0065] In some embodiments, the first identification information and the second identification information are the VIN code of the vehicle.

[0066] For example, the vehicle number VIN code of a certain ECU is verified at the offline electrical inspection station. The initialization station (personnel or equipment) uses the vehicle "operation ticket" to write the vehicle number VIN code into the ECU. The equipment at the offline electrical inspection station reads the VIN code from the ECU and scans the VIN code of the vehicle "operation ticket" at the same time. The two reading results are compared. Figure 3 If the comparison result does not match, it means that the operator has placed the wrong "operation ticket" with the vehicle. In this case, it is necessary to re-inspect the EOL process of the relevant vehicle to see if there is any error.

[0067] It can be seen that, in some embodiments, the first identification information is generated from the second identification information, and the first identification information and the second identification information may be the same.

[0068] The job ticket is a storage medium, which can be a paper with a VIN QR code or other storage medium that can be used to record information.
