Zusammenfassung:The control system selects the transmission ratio of the automatic transmission, using one or more control characteristics, addressed in dependence on the position of the throttle. A constant travel condition to allow the transmission gear ratio to be altered in a direction which delivers the same power for a lower fuel consumption, until the min. fuel consumption (bemin) for the required power output is obtained. Pref. the constant travel condition is detected by monitoring the operation of the throttle pedal, the rate of movement of the throttle pedal, the rate of variation in the vehicle velocity and detecting when the vehicle is in overdrive.
