Permanent magnet synchronous motor is the most drive motor of electric cars, to solve the problem of permanent magnet synchronous motor without position sensor speed control system has speed detection delay, error detection, slow dynamic response etc. The speed of sliding mode observer for permanent magnet synchronous motor used in electric vehicles, analyzes the structure and principle of sliding mode observer, combined with the mathematical model of PMSM, the design of electric vehicle speed sliding mode observer for permanent magnet synchronous motor. The simulation speed of sliding mode observer designed by MATLAB, the simulation results show that the speed of sliding mode observer for permanent magnet synchronous motor in electric vehicle design has the advantages of fast detection speed, small detection error, fast dynamic response etc
