PURPOSE:To reduce a speed change shock by providing an engine output torque change-control means by which engine output torque is change-controlled in a direction of suppressing fluctuation of the torque based on a rate of change in torque calculated during speed change action of a speed change mechanism. CONSTITUTION:Torque of an output shaft of a speed change mechanism is detected by a torque sensor, and a proportion of fluctuation of the torque, detected by this torque sensor, is calculated by a torque change proportion arithmetic means. In an engine output torque change-control means, during speed change action of the speed change mechanism, engine output torque is change-controlled in a direction of suppressing fluctuation of the torque being based on the fluctuation proportion of the torque. That is, by detecting torque of an output shaft, directly correlated to a speed change shock for 1 crew in a vehicle, and by supervising fluctuation of the torque during the speed change action to change-control the engine output torque, generation of the speed change shock is prevented by suppressing the fluctuation of the torque in the output shaft. |
