<p>PURPOSE:To reduce a speed change shock by performing a speed change control during this time speed change and a correction control for an engine output control, so that an actual value agrees with the target value, based on the estimation of end timing of this time speed change. CONSTITUTION:At the time of simultaneous speed change, such as followed by a speed change shock, in the first transmission (a) for performing speed change select of forward three shifts and the second transmission (b) for performing two-shift select of acceleration and equal speed, a speed change end timing correcting means (g), being based on speed change end timing estimating information from an estimating means (e), so that the actual speed change end timing agrees with the target value of decreasing the speed change shock, outputs a control correction command to at least one of the respective speed change control means (c), (d) and engine output control means (f) during the time of speed change. Accordingly, synchronization or the like of the speed change end timing of the first and second transmissions (a), (b) is attained in high accuracy. Thus, the speed change shock can be surely reduced.</p> |
