Abstract:
1. An electrically operated vehicle drive controller comprising: a differential rotating device comprising: electric generator target torque calculation processing means for calculating an electric generator target torque of said 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 the engine; determination processing means for calculating an integral term correction determining value based on an integral term component of the electric generator target torque in said integral control of the electric generator target torque calculation processing means; drive motor target torque calculation processing means for calculating a drive motor target torque based on said integral term correction determining value; electric generator torque control processing means for feedback-controlling the electric generator torque based on the electric generator target torque; and drive motor control processing means for controlling the drive motor toque based on the drive motor target torque; wherein said electric generator target torque calculation processing means calculates 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.
