Zusammenfassung:	A load drive controlling device includes a dulling controller, a dulling adjuster, and a Proportional Integral (PI) controller. The dulling adjuster sets a first electric current value for a dulling adjustment operation according to a change trend of a target electric current value in an inductive load. The dulling adjuster performs the dulling adjustment operation on the first electric current and limits a dulled value based on a guard value. The PI controller performs a PI control based on a deviation between the dulled value and an actual value of the electric current. The dulling controller sets the first electric current value and the guard value according to a change trend of the target electric current value. In such a configuration, the load drive controlling device improves an electric current response while preventing an over-accumulation of an integration value.
