Abstract:
1. A control apparatus for a vehicle that includes a power source, and an automatic transmission, connected to the power source, in which a gear is selected from among a plurality of gears with different gear ratios by selectively engaging a plurality of friction engagement elements, wherein the control apparatus boosts torque output from the power source during a torque phase when the automatic transmission upshifts, the control apparatus comprising: an engagement-pressure control portion that controls an engagement pressure for a friction engagement element to be engaged when the automatic transmission upshifts so that the engagement pressure increases to a predetermined pressure during the torque phase, and the engagement pressure increases from the predetermined pressure at a predetermined gradient when an inertia phase starts; a torque-boost permission portion that determines whether torque boost has been restricted during the torque phase, wherein when the torque-boost permission portion determines that the torque boost has not been restricted, the engagement-pressure control portion sets the predetermined pressure to a greater value, and sets the predetermined gradient to a smaller value than when the torque-boost permission portion determines that the torque boost has been restricted.
