PROBLEM TO BE SOLVED: To safely and reliably switch a travel mode while a vehicle is stopped on a slope.SOLUTION: First, a brake is applied to rear wheels so as to bring them into an unrotatable state (S2), and in that state, a connection mechanism 63 provided to a steering device 10 of front wheels is separated (S3). Then, a first rack bar 53 and a second rack bar 54 of the steering device 10 are moved by the same distance in directions opposite to each other, and the right and left front wheels are steered in opposite directions by a predetermined angle (S3). Further, while releasing a brake to the rear wheels, a brake is applied to the front wheels to bring them into an unrotatable state (S4), and in that state, the connection mechanism 63 provided to a steering device 20 of the rear wheels is separated (S5). Then, a first rack bar 53 and a second rack bar 54 of the steering device 20 are moved by the same distance in directions opposite to each other, and the right and left rear wheels are steered in opposite directions by a predetermined angle (S5).
【課題】車両を坂道に停車した状態で、走行モードの切り替えを安全かつ確実に行うこと。【解決手段】まず、後輪にブレーキをかけて回転不能の状態とし(S2)、その状態で、前輪のステアリング装置10に設けられた連結機構63を分離する(S3)。次に、ステアリング装置10の第一ラックバー53と第二ラックバー54を互いに逆方向に同距離だけ移動して、左右の前輪を逆方向に所定角度転舵する(S3)。さらに、後輪のブレーキを解除する一方で前輪にブレーキをかけて回転不能の状態とし(S4)、その状態で、後輪のステアリング装置20に設けられた連結機構63を分離する(S5)。そして、ステアリング装置20の第一ラックバー53と第二ラックバー54を互いに逆方向に同距離だけ移動して、左右の後輪を逆方向に所定角度転舵する(S5)。【選択図】図10
