PROBLEM TO BE SOLVED: To provide a vehicular steering device which can suppress a system from becoming in an unstable state, when a steering control is performed in a power steering mode.SOLUTION: When a reaction force motor 14, a reaction force motor control part 70, a steering motor 31, and a steering motor control part 50 are in a normal state, a clutch control part 90 makes a first clutch 6 in a release state, makes second and third clutches 13, 32 in a coupled state, the reaction force motor control part 70 applies steering reaction force to a steering wheel 2 by a reaction force motor 14, the steering motor control part 50 steers a steering wheel 3 by the steering motor 31. In failure of the reaction force motor 14 or reaction force motor control part 70, the clutch control part 90 makes the first and third clutches 6, 32 in the coupled state, makes the second clutch 13 in the release state, and the steering motor control part 50 generates steering auxiliary force on the steering motor 31.SELECTED DRAWING: Figure 2

    【課題】パワーステアリングモードで転舵制御が行われるときに、システムが不安定になるのを抑制できる車両用操舵装置を提供する。【解決手段】反力モータ14および反力モータ制御部70ならびに転舵モータ31および転舵モータ制御部50の正常時には、クラッチ制御部90は、第1クラッチ6を解放状態にさせるとともに第2および第3クラッチ13,32を締結状態にし、反力モータ制御部70は反力モータ14によってステアリングホイール2に操舵反力を付与し、転舵モータ制御部50は、転舵モータ31によって転舵輪3を転舵させる。反力モータ14または反力モータ制御部70の故障時には、クラッチ制御部90は、第1および第3クラッチ6,32を締結状態にさせるとともに第2クラッチ13を解放状態にし、転舵モータ制御部50は、転舵モータ31に操舵補助力を発生させる。【選択図】図2
