Control method for electric vehicle and control device for electric vehicle
A control method for an electric vehicle includes controlling a torque of a motor based on a final torque command value by calculating the final torque command value such that a vibration damping control to reduce vibrations of a driving force transmission system of a vehicle is performed on a target torque command value set based on vehicle information, calculating the final torque command value based on the target torque command value and a value obtained by multiplying a drive-shaft torsional angular velocity by a feedback gain, estimating, by use of a vehicle model that models the driving force transmission system, a dead-zone period during which a motor torque output from the motor is not transmitted to a drive-shaft torque of the vehicle, and determining whether or not the vehicle is just before stop of the vehicle.
