Abstract: The vehicle controller unit (VCU) is a core unit in new energy vehicles, responsible for overall power and energy control, as well as network and security management functions. To effectively ensure the production quality of domestic chip solution-based vehicle controllers, this paper conducts research on functional testing and end-of-line (EOL) testing technologies for production quality control of vehicle controller products. Related testing equipment is developed to achieve production quality control for domestic chip solution vehicle controllers.
