Abstract
A power train control system includes an automatic transmission shift control which detects an operational failure of an electric throttle valve based on an electric throttle opening. The transmission shift control governs or controls shifting of the automatic transmission, based on an electric throttle opening and a vehicle speed when no operational failure of the electric throttle valve is detected and based on a composite opening of an electric throttle opening and a mechanical throttle opening and a vehicle speed when operational failure of the electric throttle valve is detected.
