Abstract: As the customization level of new energy vehicles increases, the mixing of multiple configurations and colors in production lines leads to even more serious misassembly problems. To ensure consistency in vehicle assembly and avoid market quality issues and customer complaints caused by incorrect installation, this article provides an incorrect assembly countermeasure based on digital and intelligent technology. The focus is on the methods of risk identification, risk assessment, and error prevention plan development, to realize the hierarchical control of misloading risk and carry out digital and intelligent monitoring of high-risk projects. Misloading risk hierarchical control to achieve the economy of misloading control. The digital and intelligent monitoring method eliminates the misloading caused by artificial missing judgment thus improve the reliability of misinstallation risk control.

Key words: digital and intelligent technology; mistake-proofing technology; hierarchical control
