PROBLEM TO BE SOLVED: To provide a control device of a vehicle driving device that can suppress the occurrence of slip between a pulley and a transmission belt, even if irregularities on a road surface are increased suddenly, while reducing a holding pressure of the transmission belt in each pulley.SOLUTION: A control device of a vehicle driving device is characterized in the following. When it is determined to be a stable state with a little variation of the rotational speed of wheels, a holding pressure of a transmission belt in a first pulley and a second pulley is reduced more than the case determined not to be a stable state, and a specific target gear ratio in which a gear ratio is smaller than a normal target gear ratio is achieved in a continuously variable transmission, and thereby an output torque of a rotating electrical machine is increased according to a decrement of torque transmitted to the wheels from an internal combustion engine based on a difference of the gear ratio between the normal target gear ratio and the specific target gear ratio. |
