The present invention relates to a control device for electric motor vehicle and a control method for electric motor vehicle.

a speed parameter proportional to the traveling speed of the electric motor vehicle is detected, and the feedback torque for stopping the electric motor vehicle is calculated on the basis of the speed parameter.

Further, the speed parameter is estimated on the basis of a model Gp(s) of a transmission characteristic of torque input to the electric motor vehicle and the rotation speed of the motor, and the feedforward torque for compensating for a shortage of the feedback torque is calculated on the basis of the speed parameter, the feedforward torque being configured to shorten the braking distance by compensating for the shortage of the feedback torque.

When the accelerator operation amount is not larger than a predetermined value and the electric motor vehicle stops shortly, the motor torque command value Tm* is converged to zéro on the basis of the feedback torque and the feedforward torque with a reduction in the speed parameter proportional to the traveling speed.
