Abstract
A control method for an electric vehicle equipped with an electric motor as a driving source, the method including: setting a torque target value as a target value related to a driving torque of the electric vehicle based on vehicle information; calculating a basic feedback compensation value based on a parameter indicating a rotation state of the electric motor and a vehicle model of the electric vehicle; calculating a first feedback compensation value by multiplying the basic feedback compensation value by a first gain; calculating a second feedback compensation value by extracting a predetermined specific frequency component from the basic feedback compensation value and multiplying the specific frequency component by a second gain; calculating a torque command value by correcting the torque target value by the first feedback compensation value and the second feedback compensation value; and driving the electric motor based on the torque command value.
