The present invention relates to a motor-driven vehicle in which a motor control is realized by using resolver input signal stability. The motor-driven vehicle of the present invention comprises: a motor (200) for generating vehicle power; a resolver (200-1) for receiving input of a sine-wave excitation signal and transmitting a feedback signal; and an inverter controller (100) provided with an excitation signal generator (1, 1-1) for receiving feedback of the sine-wave excitation signal outputted to the resolver (200-1), and a feedback signal processing circuit (100-2) for receiving input of the feedback signal. Thereby, the motor-driven vehicle of the present invention can secure reliability in vehicle driving with improved motor controllability by reducing the amplitude of a sine-wave signal varied by temperature changes in a motor and part deviation in an inverter controller (100). In particular, the motor-driven vehicle of the present invention can provide convenience to allow the excitation signal generator (1, 1-1) to realize stability in the amplitude of a sine-wave signal with both of a dual power mode, in which positive power and negative power can be used, and a single power mode, in which only positive power can be used. |
