  "textContent": "A control device for electric motor vehicle using a motor as a traveling drive source and configured to decelerate by a regenerative braking force of the motor detects an accelerator operation amount, calculates a motor torque command value and controls the motor on the basis of the calculated motor torque command value. Further, a speed parameter proportional to a traveling speed of the electric motor vehicle is detected, and a feedback torque for stopping the electric motor vehicle is calculated on the basis of the detected speed parameter. Furthermore, the speed parameter is estimated in accordance with a state of the electric motor vehicle, and a feedforward torque is calculated on the basis of the estimated speed parameter. When accelerator operation amount is not larger than a predetermined value and the electric motor vehicle stops shortly, the motor torque command value is converged to zero on the basis of the feedback torque and the feedforward torque with a reduction in the traveling speed.",
