Control apparatus for vehicle and method of controlling vehicle

A method of controlling 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, the method comprising:

• controlling torque output from the power source so that the torque output from the power source increases to a first predetermined value during a torque phase when the automatic transmission upshifts;
• controlling an engagement pressure for a friction engagement element to be engaged when the automatic transmission upshifts so that the engagement pressure increases to a standby pressure at which an inertia phase does not start on a condition that the torque output from the power source is equal to the first predetermined value, and then the engagement pressure is maintained at the standby pressure;
• and
• controlling the torque output from the power source according to a first torque decrease control so that the torque output from the power source gradually decreases from the first predetermined value after the engagement pressure for the friction engagement element is maintained at the standby pressure.

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, the control apparatus comprising:

• first control means for controlling torque output from the power source so that the torque output from the power source increases to a first predetermined value during a torque phase when the automatic transmission upshifts;
• second control means for controlling an engagement pressure for a friction engagement element to be engaged when the automatic transmission upshifts so that the engagement pressure increases to a standby pressure at which an inertia phase does not start on a condition that the torque output from the power source is equal to the first predetermined value, and then the engagement pressure is maintained at the standby pressure;
• and
• third control means for controlling the torque output from the power source so that the torque output from the power source gradually decreases from the first predetermined value after the engagement pressure for the friction engagement element is maintained at the standby pressure.
