Engine speed controlling apparatus for internal combustion engine.

摘要

An engine speed controlling apparatus for an internal combustion engine (10) for controlling the engine speed of an internal combustion engine which has a means (16, 18) for governing the engine speed and in which a manipulated variable of said governing beans and torque are in non-linear relationships. Although a real manipulated variable and the torque are in non-linear relationships, a virtual manipulated variable in which an actual engine speed becomes a targeted engine speed is calculated assuming those relationships as being linear. The virtual manipulated variable is converted (by 38) to the real manipulated variable by using the actual non-linear relationships between the real manipulated variable and the torque, and the governor is controlled (by 40) on the basis of the converted real manipulated variable.
