<p>An internal combustion engine fuel saving control system is disclosed in which acceleration of a vehicle is initiated in a region of high engine efficiency, i.e., low fuel consumption, and continues until the actual vehicle speed equals a first preset speed which is greater than the desired traveling speed of the vehicle. When the control system detects that the actual vehicle speed is at the first preset speed, the vehicle engine is stopped (turned off) and the vehicle coasts, thereby producing vehicle deceleration. When the control system further detects that the actual vehicle speed of the coasting vehicle reaches a second preset speed which is less than the desired traveling speed, the vehicle engine is started and acceleration is again initiated. The acceleration-deceleration operation is continuously repeated resulting in an average vehicle speed which equals the desired vehicle traveling speed.</p> |
