Electrically operated vehicle drive controller, electrically operated vehicle drive control method and its program

An electrically operated vehicle drive control method comprising:

• calculating an electric generator target torque of an electric generator by feedback control for performing at least proportional control and integral control so that an electric generator rotating speed of said electric generator becomes an electric generator target rotating speed of said electric generator determined on the basis of an engine target rotating speed of an engine;
• calculating the electric generator target torque based on a speed deviation between the electric generator rotating speed detected by a rotating speed detecting section and the electric generator target rotating speed;
• wherein said electric generator target torque is calculated by adding at least a proportional term component proportional to said speed deviation by the proportional control, and the integral term component proportional to an integral value of said speed deviation by the integral control;
• calculating an integral term correction determining value based on an integral term component of the electric generator target torque in said integral control;
• calculating a drive motor target torque based on the integral term correction determining value;
• feedback controlling torque of the electric generator on the electric generator target torque;
• and
• controlling torque of a drive motor based on the drive motor target torque.
