PROBLEM TO BE SOLVED: To suppress a specific phase shift due to the category and/or magnitude of a phase shift reliably even in the case of the specific phase shift occurring.SOLUTION: A vehicular steering apparatus 11 includes: a steering reactive force generation device 15 including a steering wheel 13 and a steering reactive force motor 16; a steering reactive force motor resolver 45 for detecting a steering angle; a steering device 17 that has a steering motor 29 and is capable of steering a steering wheel 21 in the state of being mechanically separated from the steering reactive force generation device 15; a steering motor resolver 47 for detecting a steering angle; a drive control part 63 for controlling driving of the steering motor 29; and a vehicular speed sensor 51 for detecting a vehicular speed of a vehicle 10. In a case where a vehicular speed V exceeds a vehicular speed threshold Vth for the first time after an ignition switch 55 is turned on, with a specific phase shift due to category and/or magnitude of the phase shift occurring, the drive control part 63 controls driving of the steering motor 29.SELECTED DRAWING: Figure 1
【課題】位相ずれの種別・大きさに基づく特定の位相ずれが生じた場合であっても、この特定の位相ずれを適確に抑制する。【解決手段】車両用操舵装置11は、ハンドル13及び操舵反力モータ16を有する操舵反力発生装置15と、操舵角を検出する操舵反力モータレゾルバ45と、転舵モータ29を有し、操舵反力発生装置15に対し機械的に切り離された状態で転舵輪21を転舵可能な転舵装置17と、転舵角を検出する転舵モータレゾルバ47と、転舵モータ29の駆動制御を行う駆動制御部63と、車両10の車速を検出する車速センサ51と、を備える。駆動制御部63は、イグニッションスイッチ55のオン後に車速Vが所定の車速閾値Vthを初めて超えており、かつ、位相ずれの種別・大きさに基づく特定の位相ずれが生じている場合に、転舵モータ29の駆動制御を行う。【選択図】図1
