Abstract: Aiming at the teaching difficulties of cumbersome formula derivation, high correlation of knowledge points and hidden logical relations existing in Automotive System Dynamics, a core course for postgraduates majoring in vehicle engineering, this paper proposes a full-process method for constructing curriculum knowledge graphs and developing visual interactive systems. Based on Python and Neo4j graph database technology, this study establishes a fine-grained curriculum knowledge base with more than 300 knowledge entities and over 900 semantic relationships. It mainly illustrates the key technical implementations of multi-source heterogeneous data extraction, multi-strategy knowledge fusion and front-end and back-end separated visual interaction, and independently develops a background management system to ensure dynamic updating of knowledge graphs. Application verification in the teaching of this course for 2024-grade postgraduates at Tongji University proves that the system effectively improves the efficiency of knowledge system construction among 80 students from two classes. The examination scores of the experimental group rise by 12.5% compared with the control group, and the course satisfaction rate reaches 95%. It provides a popularizable model for the high-quality construction of intelligent postgraduate courses.
