Abstract: The control device for the electric vehicle determines whether or not the starting operation of the vehicle has been performed by the driver, calculates the disturbance torque estimated value Td necessary for maintaining the vehicle stop state corresponding to the disturbance acting on the vehicle, and performs a control such that the driving torque of the motor converges to the disturbance torque estimated value Td when the vehicle is determined to be just before stop of the vehicle during running or determined to have undergone the starting operation. Then, the control device for the electric vehicle controls the responsiveness of the driving torque to the disturbance acting on the vehicle, and increases the responsiveness of the driving torque of the motor compared with the responsiveness of the driving torque just before stop of the vehicle when the starting operation is determined to have been performed.
