Software configuration method of vehicle control unit

Abstract

According to a software configuration method of a vehicle control unit, the software configuration technology of the vehicle control unit is optimized, and production automation can be improved. According to the software configuration method, by defining the transfer process of software configuration information from research and development to production and the work responsibility of related departments, the process is established to ensure rapid and smooth transfer of whole vehicle software configuration information, and the whole vehicle project development requirement is met; a software configuration technology of a controller is introduced into a software configuration management system, a replacing paper transfer era modeis avoided, professional uploading and recording of software configuration are realized, and the system automatically generates a code and automatically transmits the code to an MES system; off-line equipment automatically obtains configuration information, software configuration can be achieved by scanning VIN codes, and the production efficiency is improved in a whole-process automatic mode.

Description

technical field [0001] The invention relates to the technical field of automotive software calibration, in particular to a software configuration method for a vehicle controller. Background technique [0002] With the rapid development of automobile technology, the expansion of vehicle functions and the continuous enrichment and improvement of configuration, the software development of the controller has also put forward higher and higher requirements. In the traditional development method, if one or several functions are added to the controller, a new part number may need to be added, and more and more part numbers will bring about production line assembly, spare parts management, after-sales replacement parts, cost, etc. A series of challenges. In 2008, Chery A3 vehicle body controller (BCM) introduced vehicle software configuration technology for the first time. After the technology was successfully implemented on the A3 model, it was also successfully promoted and impl...

AI Technical Summary

Problems solved by technology

[0004] 1. Manually collect and summarize software configuration information, and manually calculate the vehicle code, there is a risk of wrong code

Import the code into the production MES system, manually scan and configure the QR code on the production line, if the configuration information written into the controller is wrong, it may lead to abnormal vehicle functions

The whole process is manual operation, and there are various risks of manual misoperation;

[0005] 2. Professional paper transfer of configuration information, different departments participate in layer-by-layer transfer, the process is cumbersome and complicated,

[0006] 3. Manual management of software configuration code data and documents, lack of effective system management, difficult to inquire about after-sales replacement parts and relevant departments, and difficult to trace
