Abstract
The invention relates to a control device for an engine able to control at least one of an intake valve and an exhaust valve via a driving mechanism actuated without a torque from an output shaft of the engine, and a transmission connected to the engine. The control device includes a torque transmitting device for reducing the torque from the engine while that torque is being transmitted to an output shaft of the transmission, and control means for controlling the torque transmitting device so as to reduce the torque transmitted from the engine to the output shaft of the transmission during an upshift, controlling a engine speed to a target speed after shifting during the unshift, and controlling the torque transmitting device so as to increase the torque transmitted to the output shaft of the transmission after the engine speed is synchronized with the speed after shifting.
