To provide a four-wheel steering vehicle, in which each of front wheels and rear wheels is turned according to an input into a steering member when stopping, capable of preventing driver's unintended movement of the vehicle after the driver steers the vehicle.SOLUTION: A four-wheel steering vehicle 1, structured so that each of front wheels 3f and rear wheels 3r is turned according to an input into a steering member 8 at least when stopping, includes: an input determination apparatus 48 for determining presence/absence of a steering input into the steering member from a driver; a front wheel brake 31f for braking the front wheels; a rear wheel brake 31r for braking the rear wheels; an inclination angle sensor 40 for detecting a cross-direction inclination angle θ to a horizontal surface of a vehicle body; a rear wheel turning device 50 for releasing the rear wheel brake and turning the rear wheels, when the front wheel brake and the rear wheel brake drive and the input determination device determines that a steering input from a driver is present; and a controller 52 for prohibiting driving of the rear wheel turning device when the cross-direction inclination angle is larger than a predetermined inclination angle threshold value θ.SELECTED DRAWING: Figure 6

    【課題】 停車時において操舵部材への入力に応じて、前輪及び後輪のそれぞれが転舵される四輪操舵車両において、運転者が操舵を行ったときに、運転者の意図しない車両の移動を防止する。【解決手段】 少なくとも停車時には操舵部材8への入力に応じて前輪3f及び後輪3rのそれぞれが転舵されるように構成された四輪操舵車両1であって、操舵部材への運転者からの操舵入力の有無を判定する入力判定装置48と、前輪を制動する前輪ブレーキ31fと、後輪を制動する後輪ブレーキ31rと、車体の水平面に対する前後方向傾斜角θを検出する傾斜角センサ40と、前輪ブレーキ及び後輪ブレーキが駆動し、かつ入力判定装置が運転者からの操舵入力が有ると判定した場合に、後輪ブレーキを解除して、後輪を転舵する後輪転舵装置50と、前後方向傾斜角が所定の傾斜角閾値θ0より大きいときには後輪転舵装置の駆動を禁止する制御装置52とを有する。【選択図】 図6
