PURPOSE:To obtain a speed change ratio corresponding to a change speed of acceleration by offsetting a speed change control characteristic to the side where shift-down is dominant when a change speed of acceleration is large. CONSTITUTION:An output of an acceleration change detection means is input in a speed change control characteristic change means, so that usually, a speed change ratio is obtained according to a speed change control characteristic, and when the change speed of acceleration is large, the speed change control characteristic is offset in direction such that shift-down is dominant. Thus, when the change speed of acceleration is large, with the same acceleration opening, a speed change ratio is enlarged to increase the rev count of an engine, so as to obtain a speed change ratio corresponding to the change speed of acceleration. Accordingly, the acceleration opening can be kept from being enlarged uselessly to the utmost so as to premote saving of fuel consumption. |
