Abstract
An engine controlling system for a vehicle suitable for use with an automobile. An output reduction control amount setting means sets, when an abnormal condition detection signal of a throttle valve controlling means or a throttle valve control amount setting means is developed and a range detection signal indicates a neutral range, a control amount of an engine output reducing means such that the reduction of the output power of an engine may increase as the engine speed represented by an engine speed detection signal increases. On the other hand, when such abnormal condition detection signal is developed and the range detection signal indicates a running range, the output reduction control amount setting means sets a control amount of the engine output reducing means such that the reduction of the output power of the engine may be decreased as the accelerator pedal operation amount represented by an operation amount detection signal increases. With the system, even an abnormal condition takes place in a throttle valve controlling system, the engine can be adjusted within a predetermined range.
