Abstract
When there is a shift command for the transmission () during or immediately after clutch touch point learning, a shift operation value for the transmission () is reduced compared to what it normally is (steps STand ST). Reducing the shift operation value in this way enables the change in the rotation speed of an input rotating body at the time of a gear shift operation to be gradual if that gear shift operation is during or immediately after clutch touch point learning. As a result, inertia torque, and thus shift shock, can be suppressed.
