Abstract
An electric vehicle includes a motor as a drive source and a coupling portion coupled to another vehicle, and travels while towing the coupled vehicle, which is the other vehicle coupled to the coupling portion. A control method for such an electric vehicle includes: calculating a basic torque target value representing a torque to be output by the motor based on a vehicle operation; calculating a final torque command value, which is a final command value for the torque, by performing correction processing for reducing a longitudinal vibration component generated in the electric vehicle due to the coupled vehicle being coupled to the coupling portion on the basic torque target value, based on a dynamic characteristic of the coupling portion to which the coupled vehicle is coupled; and controlling the motor based on the final torque command value.
