摘要： PROBLEM TO BE SOLVED: To appropriately return an internal combustion engine from an unstable operation condition to a stable operation condition when controlling a significant delay in ignition timing for warming up an exhaust emission control catalyst for the internal combustion engine.
SOLUTION: In a two-dimensional space for an engine speed and a load factor, when an engine operation condition enters an unstable area caused by the amount of intake air (Fa=ON, Yes in S124) or an unstable area caused by a combustion state (Fb=ON, Yes in S130), a process is performed for exiting from each unstable area (S128 or S134). Throttle opening Ta control (S128) is performed for exiting from the unstable area caused by the amount of intake air. Ignition timing control and fuel injection timing control (S134) are performed for exiting from the unstable area caused by the combustion state. In the significant delay in the ignition timing for warming up the exhaust emission control catalyst, an unstable operation factor is determined by each unstable area and an appropriate process in response to each unstable area is performed. Therefore, the engine can be appropriately returned from the unstable operation condition to the stable operation condition.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an on-vehicle internal combustion engine capable of stopping the vehicle from traveling as promptly as possible, while suppressing the stall of the internal combustion engine when an engine operation is turned into an idle operation in the travel stop process of the vehicle.
SOLUTION: When an automobile is traveling on a road surface with a low friction coefficient upon a shift of an engine 1 to idle operation in the process of stopping the automobile from traveling, a target rotating speed is reduced by a value equivalent to a reduction in a drive request value for any auxiliary at a time point corresponding to start of reduction of the drive request value, so that the automobile stops travelling promptly without stalling the engine 1. The engine is not stalled at that time because such disturbing action to drive wheels 6 about a rotation stopping direction as external force against the drive wheels 6 from the road surface side is applied in a direction opposite to a rotation direction is reduced on the road surface with the low friction coefficient, so that the engine speed is rarely reduced due to the disturbing action.
