Abstract:
1. A control apparatus for an internal combustion engine mounted on a vehicle that executes an engine idle speed control for adjusting the engine speed to a target engine speed set in accordance with a magnitude of a drive request value for an auxiliary driven by the internal combustion engine when a vehicle speed is equal to or below a predetermined speed to idle the internal combustion engine, when stopping the vehicle from traveling, reduces the drive request value for the auxiliary when executing the engine idle speed control, and reduces the target engine speed by a value equivalent to a reduction in the drive request value after lapse of a prescribed delay time from a time point corresponding to start of reduction of the drive request value, the control apparatus comprising: a detection device that determines whether the vehicle is traveling on a road surface with low friction coefficient; and an engine speed reduction device that reduces the target engine speed by the value equivalent to the reduction in the drive request value before lapse of the delay time if it is determined that the vehicle is traveling on a road surface with low friction coefficient.
