摘要：
A method of controlling a vehicle including a permanent magnet (PM) synchronous motor is provided. The motor is controlled based on direct-axis (d-axis) and quadrature-axis (q-axis) current commands. The method includes estimating permanent magnet flux linkage based on q-axis voltage and electrical angular speed, and estimating permanent magnet temperature based on permanent magnet flux linkage and the temperature coefficient of the permanent magnet. The vehicle is controlled based on the estimated permanent magnet temperature.
