ABSTRACT:
A control apparatus for a vehicle includes an engagement-pressure control portion that increases the engagement pressure to a predetermined pressure for a friction engagement element to be engaged during a torque phase of an upshift in an automatic transmission. When the inertia phase starts, the control apparatus increases the engagement pressure at a predetermined gradient. The control apparatus also includes a torque-boost control portion that executes a torque-boost control that boosts the torque output from the power source during the torque phase; and a torque-boost permission portion that determines whether the torque-boost control should be restricted. When it is determined that the torque-boost control should not be restricted, the predetermined pressure is set to a greater value, and the predetermined gradient is set to a smaller value than when it is determined that the torque-boost control should be restricted.
