ABSTRACT:
An engagement-pressure control portion and a first torque decrease control portion are provided. The engagement-pressure control portion controls an engagement pressure for a friction engagement element to be engaged when an automatic transmission upshifts so that the engagement pressure increases to a standby pressure at which an inertia phase does not start on the condition that torque output from a power source is equal to a first predetermined value, and then the engagement pressure is maintained at the standby pressure. The first torque decrease control portion controls the torque output from the power source so that the torque gradually decreases from the first predetermined value after the engagement pressure for the friction engagement element is maintained at the standby pressure, and a predetermined condition is satisfied.
