Abstract：In this paper,by using the Incopat platform and analyzing the patent Information of global new energy vehicle and drive motor we can find that the pure electric vehicle is a hotspot of research on technology,but the study of drive motor and its control system is relatively lagging behind.The drive motor and its control system is one of the core components of new energy vehicle.Therefore,this paper focuses on the analysis of the drive motor and its control system of the patent application trend,main competitors,hot patents and applicants in the global patent layout.From these we could conclude that enterprises in Germany,Japan and South Korea have strongly the strength of research and development in drive motor areas.The amount of China's patent is relatively larger,but the patent quality is not in high level,and the research and development efforts are too scattered.At the same time,international auto giants are very good at using the patent strategy and in the global patent layout reasonably.In order to occupy the strategic high ground early and get rid of the embarrassing situation of China's automobile industry,the Chinese government,enterprises,research institutions should act with united strength and play synergy,and enterprises must act as the mainstay of technological innovation.
