Patent ID: 7548035

Claim:
A control apparatus of an electric power steering apparatus structured such as to apply a steering assist force generated by a n-phase (in this case, “n” being an integral number equal to or more than 3) motor to a steering system of a vehicle, wherein the control apparatus comprises at least (n−1) numbers of current detecting means for detecting a current Im (in this case, “m” being 1, 2, . . . , n) in each of phases of said motor, a current command value calculating means for outputting a current command value Imref (in this case, “m” being 1, 2, . . . , n) in each of the phases, and n numbers of current control means, and the control apparatus executes a current control of each of the phases by said current control means having said current command value Imref in each of the phases and said current Im in each of the phases as an input.
