PROBLEM TO BE SOLVED: To suppress contact noise on a power transmission route which occurs upon K-turn steering.SOLUTION: A clutch 19 which couples a steering shaft 12 and a pinion shaft 18 as disconnectable is installed between: a steering input mechanism Stin which the steering shaft 12 is rotated by steering operation by a driver; and a steering output mechanism Stin which a wheel is steered by rotation of the pinion shaft 18. And, a first steering motor M1 and a second steering motor M2 which can give steering force to the steering output mechanism Stare provided. Then, in a case that the first steering motor M1 and the second steering motor M2 are drive-controlled, a reverse timing of the first steering motor M1 and a reverse timing of the second steering motor M2 are made to differ from each other by a predetermined minute time TL, when at least steering operation direction of the driver is reversed. |
