PROBLEM TO BE SOLVED: To suppress the occurrence of a situation in which a vehicle is guided in an unintended direction and assists in appropriate running even if a crash accident occurs to the vehicle.SOLUTION: A steering gear comprises: a steering reaction force generator 15 including a steering reaction force motor 16 applying a steering reaction force with respect to a steering input of a driver of a vehicle V; a steering device 17 including a steering motor 29 applying a steering force for steering steered wheels 21a and 21b in a state of being mechanically disconnected from the steering reaction force generator 15; a steering control unit 65 controlling the steering reaction force motor 16 and the steering motor 29 to operate; and a crash detector 61 detecting a crash of the vehicle V. If the crash detector 61 detects the crash of the vehicle V, the steering control unit 65 controls the steering reaction force motor 16 to operate so as to increase the steering reaction force from that before detection.

    【課題】車両に衝突事故が生じた場合であっても、同車両が意図しない方向へと誘導される事態の発生を抑制し、適切な走行を補助する。【解決手段】車両Vの運転者による操舵入力に対して操舵反力を付与する操舵反力モータ16を有する操舵反力発生装置15と、この操舵反力発生装置15に対して機械的に切り離された状態で転舵輪21a,21bを転舵するための転舵力を付与する転舵モータ29を有する転舵装置17と、操舵反力モータ16及び転舵モータ29の動作制御を行う操舵制御部65と、車両Vの衝突を検知する衝突検知部61と、を備える。操舵制御部65は、車両Vの衝突が衝突検知部61により検知された場合、操舵反力を衝突の検知前と比べて増大させるように操舵反力モータ16の動作制御を行う。【選択図】図1
