Hybrid electric vehicle transmission system knowledge graph construction method, reasoning method and rapid design system

The invention discloses a knowledge graph construction method for a hybrid electric vehicle transmission system, and the method comprises the steps: building a knowledge ontology model of the hybrid electric vehicle transmission system on the basis of constructing a knowledge base and an instance library of the hybrid electric vehicle transmission system, and combining the characteristics of the hybrid electric vehicle transmission system; a hybrid electric vehicle transmission system knowledge ontology model is set to comprise a transmission scheme ontology, a component structure ontology, a parameter calculation model ontology and a design process knowledge relationship set, and then through knowledge processing including entity recognition, relationship extraction and entity alignment, new knowledge can be accurately and efficiently extracted from big data; knowledge mining and knowledge diffusion are facilitated, and the application range of the knowledge graph is improved from data retrieval and qualitat
