The present invention relates to a method of controlling the vibration of an electric vehicle using a brake acceleration sensor. More particularly, the present invention relates to a method of controlling the vibration of the electric vehicle using a brake acceleration sensor, capable of reducing vibration based on an acceleration detection signal of the brake acceleration sensor when the electric vehicle is driven at a low speed. In other words, according to the present invention, a vibration component is extracted from a detection signal of the brake acceleration sensor when the electric vehicle is driven at a low speed, and the vibration component is stored in a memory according to rotor positions. Then, motor instruction torque is compensated by using compensation torque obtained by performing iterative learning control for the stored data. Thus, the reduced performance of the motor vibration can be improved at a low speed. |
