ABSTRACT:
A power train control system for an internal combustion engine of a motor vehicle. Opening of a throttle valve is electrically controlled in response to an accelerator pedal depression signal generated by an accelerator pedal position sensor and indicating depression depth of an accelerator pedal. A backup operation control of the engine is performed by controlling an auxiliary air flow which bypasses the throttle valve in dependence on the accelerator pedal depression signal upon occurrence of abnormality in a throttle valve control system. During the backup operation, a speed range shift pattern of an automatic transmission is changed over to a backup operation oriented pattern from a normal operation oriented pattern. The power train control system allows the motor vehicle to run even when a failure occurs in the throttle valve or a throttle control system in the fully closed state of the throttle valve.
