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 |
