摘要： A motor control device includes: a storage configured to store reference Lissajous values; and a controller configured to apply an excitation signal to a resolver; receive an output signal output from the resolver, to obtain a Lissajous value corresponding to the received output signal, to determine that an external noise is input when the obtained Lissajous value is different from the reference Lissajous values, and to control driving of a motor based on the obtained Lissajous value when the obtained Lissajous value is equal to any one of the reference Lissajous values. A vehicle having the motor control device may further include a battery configured to transmit power to the motor and to be charged by regenerative braking of the motor.

摘要： A method and a system for preventing surge of a vehicle may include: determining whether an engine operation mode is a particulate filter regeneration mode or a catalyst desulfurization mode; determining, when the engine operation mode is the particulate filter regeneration mode or the catalyst desulfurization mode, a torque change; determining whether the torque change is smaller than a predetermined value; determining, when the torque change is smaller than the predetermined value, whether an intake pressure is higher than an exhaust pressure by at least a predetermined pressure; and opening, when the intake pressure is higher than the exhaust pressure by at least the predetermined pressure, an exhaust gas recirculation (EGR) valve and a throttle valve.
