A control method for an electrically driven vehicle includes a motor configured to supply the vehicle with a braking force or a driving force corresponding to an accelerator operation amount. The control method is for controlling the braking force when the accelerator operation amount is less than a predetermined value and controlling the driving force when the accelerator operation amount is the predetermined value or more. In the control method, a torque target value at which the motor is caused to output a braking/driving torque corresponding to the accelerator operation amount is calculated, a disturbance torque acting on the motor as a resistance corresponding to a road surface gradient is estimated, a correction to remove the disturbance torque from the torque target value is performed, and the motor is controlled in accordance with the torque target value subjected to the correction. A correction amount in the correction is reduced in a downhill road when the accelerator operation amount is less than the predetermined value and a vehicle speed is larger than a predetermined vehicle speed.
