Abstract
An integrated control apparatus includes an internal combustion engine, a stepped automatic transmission, a power train manager, and an engine controller. The power train manager is configured to: output a target torque and a forenotice torque to the engine controller; start lowering of the target torque after a specified time elapses from a timing of an upshifting instruction; lower the forenotice torque prior to the lowering of the target torque. The engine controller is configured to: start a reduction in an air amount in accordance with a magnitude of lowering of the forenotice torque; start reducing the air amount from a time when the lowering of the forenotice torque is started until a time when the lowering of the target torque is started; and adjust an air-fuel ratio in accordance with a deviation between the target torque and a torque that is estimated from a lean air-fuel ratio and the air amount.
