Abstract
An oil temperature increasing system and method for an eco-friendly vehicle includes: an oil-temperature detector configured to detect a temperature of oil flowing to a motor and a transmission by an electric oil pump; and a controller configured to receive a detection signal of the oil-temperature detector, and apply a current for increasing temperature to the motor when the oil temperature is less than a predetermined reference temperature. A temperature of the motor is increased by the current applied to the motor, such that the oil temperature is increased by heat of the motor.
