Ambient temperature calculating modeling method using distorted ambient temperature compensation

An ambient temperature determining modeling method using distorted ambient temperature compensation may include, (A) a distortion compensation factor applying step of applying a coolant temperature, an intake air temperature, an air volume, a vehicle speed, a soak time, and a gradient to ambient temperature determining modeling, (B) an ambient temperature learning prohibiting step of checking a "Hot Soak" condition and a "Long Idle" condition, and setting ambient temperature model learning prohibition when the "Hot Soak" condition and the "Long Idle" condition are satisfied at the same time, and (C) an ambient temperature distortion removing step of determining ambient temperature update conditions when the "Hot Soak" condition and the "Long Idle" condition are not satisfied at the same time, and adding the gradient to determine an ambient temperature.
