Patent ID: 8840525

Claim:
A control apparatus for an internal combustion engine, for controlling a clutch provided between the internal combustion engine of a vehicle and an automatic transmission, comprising: an accelerator opening-degree detection unit for detecting a pressing amount of an accelerator; a fuel-supply stopping unit for stopping fuel injection to the internal combustion engine when the accelerator is not pressed down; and a clutch direct-coupling ratio control unit capable of controllably changing a power amount transmitted by the clutch from engagement for direct coupling to disengagement of the clutch, wherein, when the accelerator is pressed down after the clutch is disengaged in a fuel-supply stop state, when vehicle speed is equal to or higher than a predetermined value which allows the vehicle to rotate the engine, the clutch becomes engaged in a slipping manner to engage an axle of the vehicle with the engine, and after the internal combustion engine rpm becomes equal to or higher than a target cranking rpm, the fuel supply is restarted and the internal combustion engine is restarted, when the vehicle speed is less than the predetermined value, the internal combustion engine is restarted by a starter which assists in starting the operation of the engine.
