<p>PURPOSE: An EGR flow control apparatus and method for a vehicle are provided to prevent backflow of intake air by tuning the opening degree of an electronic valve according to pulsating pressure which varies according to load. CONSTITUTION: An EGR flow control method for a vehicle comprises the steps of: determining whether an EGR valve is in operation(S103), detecting the rpm and load of an engine during the operation of the EGR valve(S104), determining the operation period and opening degree of an electronic valve(S105), and operating the electronic valve according to the determined operating period and opening degree to control the flow rate of exhaust gas recirculated(S106,S107).</p> |
