PROBLEM TO BE SOLVED: To provide an electric power steering device etc., capable of reducing abutting sounds of both a mechanical stopper and a rack stopper.SOLUTION: While taking attenuation corrections on a rack stopper side with a rack-side attenuation correction signal Dr computed by a rack-side attenuation correction quantity arithmetic part 21 into consideration, attenuation corrections on a mechanical stopper side with a mechanical-side attenuation correction signal Dm computed by a mechanical-side attenuation correction quantity arithmetic part 23 is taken into consideration to compute a motor command signal Io, and then while an abutting sound of a rack stopper is reduced, an abutting sound of a mechanical stopper can be reduced.SELECTED DRAWING: Figure 3
【課題】メカストッパとラックストッパの双方の当接音を低減し得る電動パワーステアリング装置等を提供する。【解決手段】ラック側減衰補正量演算部21で演算したラック側減衰補正信号Drによりラックストッパ側の減衰補正を考慮しつつ、メカ側減衰補正量演算部23で演算したメカ側減衰補正信号Dmによりメカストッパ側の減衰補正を考慮してモータ指令信号Ioを演算するようにしたことで、ラックストッパの当接音を低減しつつ、メカストッパの当接音についても低減することができる。【選択図】図3
