PURPOSE:To prevent the occurrence of a large speed shift shock, by operating an output reducing means by means of a torque controlling means when a decision that a transmission on a down shift side has first completed speed shift, is made by means of a speed shift completion time point detecting means. CONSTITUTION:In the case of the shift directions of the 1st, 2nd transmissions a, b being different, it is detected by means of a speed shift completion time point detecting means d that a down shift side transmission detected by means of a shift direction deciding means c has first completed speed shift, and then, a torque controlling means f reduces the output torque of an up shift side transmission at an inertia phase period through an output torque reducing means e. Thus, the drastic reduction of a speed shift shock can be made. Also, the simplification of the constitution of a speed shift controller can be realized by constituting the output torque reducing means as an engine output reducing means. |
