PROBLEM TO BE SOLVED: To provide a traveling method of a traveling vehicle which is capable of performing uniting regardless of a positional relationship between a bed body part and the traveling vehicle, and keeping safety without a collision even when there is an obstacle in a traveling route of the traveling vehicle.SOLUTION: A traveling method of a traveling vehicle is the traveling method of a traveling vehicle 10 which travels to a housing area 13 whose one side is formed as an entrance port 12 on the basis of a measurement result in a coordinate measurement part 14. After measuring a first point P1 and a second point P2 on the entrance port side of the housing area 13 and at least one of a third point P3 and a fourth point P4 on the back side of the housing area 13 using the coordinate measurement part 14, when the third point P3 or the fourth point P4 on the back side of the housing area 13 cannot be measured, the third point P3 or the fourth point P4 that cannot be measured is measured after moving the traveling vehicle 10 in a direction along the entrance port 12 of the housing area 13, and the traveling vehicle 10 is made to travel so as to be housed in the housing area 13 on the basis of the first point P1, the second point P2, the third point P3 and the fourth point P4.COPYRIGHT: (C)2014,JPO&INPIT【課題】ベッド本体部と走行車との位置関係によらず合体でき、かつ、走行車の走行経路に障害物があっても衝突せずに安全を保つことができる走行車の走行方法を提供する。【解決手段】本発明の走行車の走行方法は、一方が進入口12となる収容領域13へ向けて座標測定部14での測定結果に基づいて走行する走行車10の走行方法であって、座標測定部14を用いて収容領域13の進入口側の第一点P1および第二点P2と収容領域13の奥側の第三点P3および第四点P4の少なくともいずれかを測定した後、収容領域13の奥側の第三点P3または第四点P4が測定できない場合、走行車10を収容領域13の進入口12に沿った方向に移動させた後に、測定できなかった第三点P3または第四点P4を測定し、第一点P1、第二点P2、第三点P3および第四点P4に基づいて、収容領域13に収容されるように走行車10を走行させる。【選択図】図1
