Abstract

An ECU of an engine performs control to keep a constant engine speed when a load factor is equal to or less than a predetermined value, and to reduce and correct the engine speed in accordance with an increase in the load factor when the load factor exceeds the predetermined value. The ECU is provided with a reference droop control correction amount calculation unit (36), a correction amount adjustment map storage unit, and a post-adjustment correction amount calculation unit (38). The reference droop control correction amount calculation unit (36) obtains an engine speed reference reduction correction amount NBD that is increased at a constant rate in accordance with the increase in the load factor from the predetermined value. The correction amount adjustment map storage unit stores, as a correction amount adjustment map (111), a subtraction factor that varies depending on the load factor. On the basis of the engine speed reference reduction correction amount NBD and the subtraction factor, the post-adjustment correction amount calculation unit (38) calculates an engine speed reduction correction amount ND as an amount by which the engine speed is reduced and corrected in accordance with the increase in the load factor when the load factor exceeds the predetermined value.
