  "textContent": "A control method for an electric vehicle according to the present embodiment is a control method for an electric vehicle in which an electric motor 4 is used as a traveling drive source and deceleration is performed by a regenerative braking force of the electric motor 4. The control method includes: acquiring an accelerator operation amount; acquiring a total mass M^ of the electric vehicle; estimating a disturbance torque acting on the electric vehicle; acquiring an angular velocity of a rotary body correlated with a rotation velocity of a driving shaft 8 for driving the electric vehicle; estimating a vehicle body speed of the electric vehicle by using a transmission characteristic Gp(s) from the angular velocity of the rotary body to a speed of the electric vehicle; calculating a second torque target value Tm2 (torque specified value) for the electric motor 4 based on the acquired total mass M^ of the electric vehicle; and controlling, based on the second torque target value Tm2, a torque generated in the electric motor 4. The control method further includes: converging the second torque target value Tm2 to a disturbance torque Td as an estimated vehicle body speed V decreases, when the accelerator operation amount is equal to or less than a predetermined value and the electric vehicle stops.",
