Abstract
An apparatus and a method to stably run an electrically operated vehicle is disclosed. The invention has an electric generator target torque calculation processor for calculating electric generator target torque showing a target value of electric generator torque by feedback control for performing at least integral control; a determination processor for calculating an integral term correction determining value on the basis of an integral term component of the electric generator target torque in the integral control; and a drive motor target torque calculation processor for calculating drive motor target torque showing a target value of drive motor torque on the basis of the integral term correction determining value. Since the drive motor target torque is calculated on the basis of the integral term correction determining value, no error is generated in the drive motor target torque and the electrically operated vehicle is stably run.
