Patent ID: 7263959

Claim:
A control apparatus of an internal combustion engine comprising: a detecting unit that detects a number of revolutions of the internal combustion engine; a combustion control unit that executes a fuel cut when the number of revolutions of the engine is at a predetermined value; an inertia energy control unit that controls inertia energy of the engine, by using a motor for driving the engine, to be in a predetermined state in association with the fuel cut, at a timing in a process of stopping the engine; and a stop control unit which stops the engine at a predetermined crank angle position by utilizing the inertia energy, wherein the inertia energy control unit controls a number of revolutions of the engine to be within a range of a predetermined number of engine revolutions by performing a motoring of the engine for a predetermined time period using the motor, and wherein the stop control unit stops the engine by terminating the motoring after the predetermined time period has passed.
