Abstract:
It is an object of the present invention to provide a control device for an internal combustion engine capable of appropriately controlling compression ratio and ignition timing before the target compression ratio that is set according to humidity is attained. A control device for an internal combustion engine controls the internal combustion engine including a cylinder, humidity detection means for detecting humidity of outside air supplied to the cylinder, a variable compression ratio mechanism for changing a compression ratio of the cylinder, and an ignition device igniting air-fuel mixture in the cylinder, and the control device includes: a compression ratio control unit controlling the variable compression ratio mechanism; and an ignition control unit controlling ignition timing of the ignition device, wherein corresponding characteristics between compression ratio and ignition timing are determined for each humidity according to a predetermined condition of an operation state of the internal combustion engine, the compression ratio control unit determines a target compression ratio of the variable compression ratio mechanism according to the detected humidity, and while the variable compression ratio mechanism changes a compression ratio to the target compression ratio, the ignition control unit controls the ignition device on the basis of corresponding characteristics determined according to the detected humidity.

Claim (Index 3):
The control device for the internal combustion engine according to  claim 1 ,\n wherein the internal combustion engine further includes an EGR mechanism, the corresponding characteristics between the compression ratio and the ignition timing are determined for each effective EGR rate defined by the humidity and the EGR rate according to a predetermined condition about an operation state of the internal combustion engine, and while the variable compression ratio mechanism changes a compression ratio to the target compression ratio, the ignition control unit controls the ignition device on the basis of the corresponding characteristics determined according to the detected effective EGR rate.
