Abstract
A control method of a vehicle having an exhaust gas recirculation (EGR) system includes efficiently controlling a temperature of recirculated exhaust gas and, even when the temperature of recirculated exhaust gas excessively increases, damage to hardware, such as an intake manifold or parts of the exhaust gas recirculation system can be prevented. The control method includes: detecting the temperature of exhaust gas recirculated to an engine intake system by the EGR system; entering into a protection mode so as to control the temperature of the recirculated exhaust gas; determining a correction value such that the controller controls the temperature of the recirculated exhaust gas; and correcting an engine control value by using the determined correction value and controlling an engine according to the corrected engine control value.
