To provide a reliable electric vehicle drive controller which avoids nonconformity such as torque deficiency, step out, etc. by computing an accurate velocity estimate, corresponding to various conditions in operation.

This controller has a control unit 28 for inverter which drives a motor 7 for driving an electric vehicle, a velocity estimator 14 which estimates the revolution of the motor 7, based on the applied voltage or current of the motor 7, and a velocity predictor 15 which predicts the revolution of the motor 7, based on a torque command. The velocity predictor 15 predicts the velocity, based on at least one of the seat-load rate, the gradient, and the revolution of the drive motor, and the control unit 28 performs the vector control, using a velocity predicted value in the vicinity of the zero revolution of the motor 7, and performs the vector control, using the velocity estimate in other regions.
