Error-proofing and traceability management method applied to commercial vehicle electronic control system

Abstract

The invention discloses an error-proofing and traceability management method applied to an electric control system of a commercial vehicle, a development engineer compiles information of electric control elements into an electric control element matrix item by item in a PLM (Personal Language Model) according to the structure of a whole vehicle super BOM (Bill of Material), the electric control element matrix is called by the whole vehicle according to a function group relationship, and an EOL (Ethernet over Language) engineer establishes an error-proofing and traceability management system based on an electric control element matrix data source of the development engineer. Developing software, and locking the information in the variable database; after the DMS system receives a customer order and transmits the customer order to the SAP system, the SAP system creates an order material list based on data in the PLM system, transmits the order material list to the MES system, and then transmits the order material list to an installation station; triple mistake-proofing management and control are carried out on the installation station, a triple mistake-proofing management mechanism can effectively manage and control the design end, the material storage management end and the supply chain management end, PLM, SAP, MES and EOL data are communicated, real-time inspection and feedback are carried out in the production process, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an error prevention and traceability management method using an electronic control system of a commercial vehicle. Background technique [0002] Automotive electronic control is the automotive electronic control system, which is basically composed of sensors, electronic controllers (ECU), drivers, and control program software. It is used in conjunction with the mechanical system on the vehicle, and uses cables or radio waves to transmit information to each other. "Mechanical and electrical integration", in recent years, with the application of electronic technology, computer technology and information technology, automotive electronic control technology has developed rapidly, especially in the aspects of control accuracy, control range, intelligence and networking. A big breakthrough, automotive electronic control technology has become an important symbol to measure the devel...

Problems solved by technology

At present, the common traceability system of the production line adopts QR code scanning and traceability. Operators use scanning equipment to scan the QR code on the electronic control components. It is essentially a storage unit for material information. The obtained material information may be related to the electronic control components. The internal software information is inconsistent. When the electronic control system of the vehicle fails, the traditional method of manual visual inspection scans and traces the electronic control components in turn, which is inefficient. At the same time, the software information inside the electronic control components may not be able to be checked, which is inconvenient to manage.
