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, a first determination processor for calculating an inertia correction determining value, a second determination processor for calculating an integral term correction determining value, a determining mode switching condition judgment processor, and a drive motor target torque calculation processor. When a determining mode switching condition exists, the drive motor target torque calculation processor switches between a first determining mode for calculating drive motor target torque, and a second determining mode for calculating the drive motor target torque. When the determining mode switching condition exists, the first determining mode and the second determining mode are switched so that the drive motor target torque is calculated on the basis of the integral term correction determining value.
