PROBLEM TO BE SOLVED: To solve a problem that an accurate detection signal cannot be generated and accurate control cannot be performed since detection signals of a pedal effort and a manual force for performing auxiliary drive are unstable, in an electric vehicle capable of performing the auxiliary drive of an electric motor. SOLUTION: This electric vehicle includes an AGC (Automatic Gain Control) circuit compensating occasionally changing detection signals of a non-contact sensor receiving an influence of the pedal effort and the manual force and a non-contact sensor hardly receiving the influence of the pedal effort and the manual force into each usable signal. After obtaining an accurate phase difference from the signals, a torque amount is calculated, signals for performing the auxiliary driving are generated and made as control signals of the electric motor.
