Abstract
A vehicle is provided with an exhaust gas recirculation system and an automatic transmission which shifts in accordance with a plurality of shift patterns including a shift pattern in which upshift occurs at relatively low vehicle speeds and a shift pattern in which upshift occurs at relatively high vehicle speeds. The exhaust gas recirculation system includes an exhaust gas recirculation control mechanism which reduces the amount of exhaust gas to be returned to the combustion chamber when the former shift pattern is selected.
