Abstract
If the accelerator pedal condition is a power-on condition and the gearshift type is an upshift, or the accelerator pedal condition is a power-off condition and the gearshift type is a downshift, then a torque for engaging the next-gear-position gearshift means is established based on the engine torque to be transmitted from the engine to the next-gear-position gearshift means, and an inertia torque required to make the rotational speed of the input member of the next-gear-position gearshift means vary as desired with respect to the gearshift. If the accelerator pedal condition is a power-on condition and the gearshift type is a downshift, or the accelerator pedal condition is a power-off condition and the gearshift is an upshift, then the ratio between the rotational speeds of the input and output members of the next-gear-position gearshift means is detected. The torque for engaging the next-gear-position gearshift means is lowered after the gearshift is started until the detected rotational speed ratio reaches a predetermined value. After the detected rotational speed ratio has reached the predetermined value, the engaging torque is set to a vaslue large enough to engage the gearshift means.
