Abstract:
The present invention discloses a method and apparatus for controlling a motor for an electric vehicle. The method and apparatus calculates the current acceleration α of the motor according to the detected rotor position values in real-time, and if the current acceleration α is greater than a predetermined forward acceleration α0, the output torque of the motor is decreased. If the acceleration α is less than a predetermined backward acceleration α1, then the output torque of the motor is decreased. Thus, when the vehicle travels from a normal road surface to a smooth road surface, the decrease or increase output torque may suppress the abrupt speed variations.
