Abstract:
1. An internal combustion engine control method comprising: a control apparatus for determining a target RPM of the internal combustion engine based on an operational amount of an operating member independent of fluctuations in a load of the internal combustion engine; the control apparatus performing control such that an actual output RPM is close to the target RPM; the control apparatus performing a temporary increase control in which the target RPM is temporarily increased with respect to a basic target RPM previously determined in correspondence with the operational amount; the control apparatus performing an acceleration control in which the target RPM is gradually increased at an increase rate equal to or greater than a predetermined increase rate; and in a state in which the temporary increase control and the acceleration control are performed simultaneously, when the temporary increase control is canceled, the control apparatus setting an increase rate of the target RPM at a level less than an increase rate of the basic target RPM corresponding to the operational amount so that the target RPM does not become lower than a present RPM, and the control apparatus gradually matching the target RPM with the basic target RPM.
