PROBLEM TO BE SOLVED: To provide a control device for a vehicle driving system to perform cylinder pause operation in which an engine is operated while combustion in some of the cylinders are stopped, configured to reduce shock generated when restored from the cylinder pause operation.SOLUTION: When a request for cylinder restoration is generated during cylinder pause operation in acceleration, an automatic transmission 12 is shifted up, and cylinder restoration is executed while overall torsion stiffness of the power transmitting system is increased. Distortion of the power transmitting system at cylinder restoration is reduced, to reduce shock (push-out feeling). The timing of the shifting up and the timing of executing the cylinder restoration are controlled so that the torque of an inertia phase due to the shift up and the torque due to cylinder restoration transfer to each other smoothly. The smooth transfer of the torque of the inertia phase due to the shift up and the torque due to cylinder restoration suppresses the sense of deceleration due to shift up, to maintain the sense of acceleration. |
