Abstract: With the automobile industry "new four modernizations" proposed, electrification has become an inevitable trend in the field of automobile development, and the drive motor, the core component of the electric vehicle, is the focus and difficulty of the research. The position detection of electric vehicles driving motor is studied, real-time detection and acquisition of driving motor position are realized by resolver and decoder chip AD2S1210 and Infineon control chip. Experiments show that the system has high reliability and real-time characteristics.
