PROBLEM TO BE SOLVED: To provide a vehicular steering device that is able to travel a vehicle while maintaining steering performance even in a case where an abnormal state in communication arises between at least one of a left steering control device and a right steering control device and a host control device.SOLUTION: A left steering ECU 22 includes a switching control section 59L that switches between a first control mode in which a left steering motor 4L is controlled such that a steering angle of a left steering wheel is equal to a left target steering angle received from a host control device and a second mode in which the left steering motor 4L is torque-feedback-controlled such that a steering angle of a left steering wheel is equal to an angle corresponding to a neutral position. The switching control section 59L normally sets a control mode to the first control mode and, when an abnormal state in communication arises between the host control device and the left steering ECU 22, it switches the control mode to the second control mode.SELECTED DRAWING: Figure 3

    【課題】左転舵制御装置および右転舵制御装置のうちのいずれか一方と上位制御装置との間に通信異常が発生したとしても、操向性能を維持しながら車両を走行させることができるようになる車両用操舵装置を提供する。【解決手段】左転舵ECU22は、左転舵輪の転舵角が、上位制御装置から受信した左目標転舵角と等しくなるように左転舵モータ4Lを制御する第1制御モードと、左転舵輪の転舵角が中立位置に対応する角度となるように、左転舵モータ4Lをトルクフィードバック制御する第2制御モードとを切り替える切替制御部59Lを含んでいる。切替制御部59Lは、通常時は、制御モードを第1制御モードに設定し、上位制御装置と左転舵ECU22との間に通信異常が発生したときには、制御モードを第2制御モードに切り替える。【選択図】図3
