Abstract
A control device for electric motor vehicle using the motor as the traveling driving source and configured to decelerate by a regenerative braking force from the motor detects the accelerator operation amount, calculates the disturbance torque estimated value, and detects or estimates the resistance component unrelated to the gradient from the vehicle state. The control device for electric motor vehicle corrects the disturbance torque estimated value according to the detected or estimated resistance component unrelated to the gradient. The motor is controlled on the basis of the motor torque command value. When the accelerator operation amount is equal to or less than the predetermined value and the electric motor vehicle is just before the stop of the vehicle, the motor torque command value converges to the corrected disturbance torque estimated value in conjunction with the reduction of the rotation speed of the motor.
