Abstract
A control device includes an input member drivingly coupled to at least one of an internal combustion engine and a rotating electrical machine as driving force sources of a vehicle. When downshifting or upshifting the control device controls the engagement pressure of a direct coupling clutch to a pressure lower than the direct coupling limit engagement pressure during downshifting, when downshifting in a state in which required input torque, which is torque that is required to be transferred to the input member, is set to a positive torque, and the control device controls the engagement pressure of the direct coupling clutch to a pressure equal to or higher than the direct coupling limit engagement pressure during downshifting or upshifting, when performing downshifting in a state in which the required input torque is set to a negative torque, or when performing upshifting regardless of the required input torque.
