  • Patent number: 5128869
    Abstract: An engine controlling system for a vehicle which is suitable for use with an automobile. When an accelerated/decelerated condition detecting means detects an inoperative condition of an acceleration/deceleration instructing means and develops a non-operation detection signal, a constant speed running designation signal is developed from a constant speed running designating means, and an aimed speed setting means sets a speed of the vehicle to be aimed when the vehicle should make constant speed running. Then, a constant speed running controlling means controls an engine output adjusting means in response to a running speed detection signal from a running speed detecting means so that the running speed of the vehicle may become equal to the aimed speed. The engine output adjusting means thus adjusts the output power of an engine carried on the vehicle. Consequently, the vehicle thereafter makes constant speed running at a speed equal to the aimed speed.
