PURPOSE:To decrease a speed change shock by outputting a signal of executing an upshift after a rotational speed is increased larger than a value of multiplying the rotational speed by speed change ratio of a speed change mechanism. CONSTITUTION:When an output shaft rotational speed is increased larger than a value of multiplying an input shaft rotational speed by speed change ratio, a signal of upshifting the other speed change mechanism 12(14) is immediately output. A condition that the output shaft rotational speed is increased larger than a value of multiplying the input shaft rotational speed by the speed change ratio is a condition that one-way clutches CW1, CW2 are raced, that is, a condition that a transmission is placed neutral, and in this condition, even when an upshift is performed, a speed change is performed in a condition that an engine side and a transmission output shaft side are separated. Accordingly, almost no torque fluctuation according to the speed change is transmitted to a car body. In this way, a speed change shock can be decreased. |
