Abstract
Provided is a system and method for calibrating an offset of a resolver in a motor of a vehicle. More specifically, a current is applied to the −d-axis of the motor, the Vq, Vd, Iq, and Id of the motor is measured and a power input to the motor is calculated by a controller, and when the input power is not within a predetermined range, the controller adjusts the offset of the resolver to a positive or negative value accordingly.
