ABSTRACT:
To provide the driver with a driving feeling which faithfully keeps up with various running states of the vehicle and running requirements of the driver by finding an accommodation coefficient indicating a running state by fuzzy inference. A target rotational speed of the engine is set on the basis of the accommodation coefficient found during the previous step. The change-gear ratio of the nonstage transmission is controlled so as to result in the target rotational speed of the engine set at the immediately previous step. A transmission control unit includes an accommodation coefficient fuzzy-inferring control, a target engine rotational speed setting control and a change-gear ratio controlling member. Inputting the change-gear ratio R, the throttle opening O, the speed v of the vehicle and the change in vehicle speed per unit time (or the acceleration) G, the accommodation coefficient fuzzy-inferring control finds a rate of change A in accommodation coefficient A by using fuzzy rules set in advance. The target engine rotational speed setting control sets a target rotational speed NE of an engine on the basis of at least the accommodation coefficient A and the speed V of the vehicle. The change-gear ratio controlling member controls the change-gear ratio R of the non-state transmission to provide a rotational speed N of the engine equal to the target engine rotational speed NE.
