Control system for electric vehicle
 A control system for an electric vehicle includes an accelerator opening detecting device for detecting a position of an accelerator, and an output command value calculating device connected to the accelerator opening detecting device for calculating an output command value of a drive motor of the electric vehicle based upon the detected accelerator opening. A motor control device is connected to the output command value calculating device, and controls the output of the motor based upon the output command value. An accelerator opening learning device learns actual accelerator opening positions, and includes at least one of a full-closure learning apparatus for generating a full-closure determined value of the accelerator based upon an output of the accelerator opening detecting device, and a full-open learning apparatus for generating a full-open determined value based upon the detected accelerator opening. The system also includes an output command value limiting device for limiting the output command value output by the output command value calculating device until the accelerator opening learning device has generated the full-closure determined value and the full-open determined value. This configuration reduces the rough and unstable output changes of a motor until the learning has been completed.
