TRAVEL AUXILIARY DEVICE FOR WORK VEHICLE AND WORK VEHICLE INCLUDING THE SAME
To provide a travel auxiliary device for work vehicle capable of assisting travel of a work vehicle so as to safely travel on a passage member having limited width, and to provide a work vehicle including the same.SOLUTION: A travel auxiliary device 3 includes: a distance information acquisition part 20 for acquiring information of distance distribution around a shovel 10; and a calculation part 304 for calculating side edge location information of a pair of ladder members 50 from distance information. The calculation part 304 calculates each inter-adjacent-point distance which is a distance between measurement points adjacent to each other in the main scan direction (left-to-right direction), regarding a plurality of measurement points contained in the distance information acquired by the distance information acquisition part 20, extracts a first measurement point group constituted by measurement points in which the inter-adjacent-point distance exceeds a preset distance threshold, and calculates the side edge location information (left side edge estimation line 50L, right side edge estimation line 50R) based on the distance information in the first measurement point group.SELECTED DRAWING: Figure 6
【課題】限られた幅を有する通路部材上を安全に走行できるように前記作業車両の走行を補助することが可能な作業車両の走行補助装置およびこれを備えた作業車両を提供する。【解決手段】走行補助装置３は、ショベル１０の周囲の距離分布の情報を取得する距離情報取得部２０と、前記距離情報から一対の梯子部材５０の側縁位置情報を演算する演算部３０４とを有する。演算部３０４は、距離情報取得部２０によって取得された距離情報に含まれる複数の測定点について、主走査方向（左右方向）において互いに隣接する測定点同士の距離である隣接点間距離をそれぞれ演算し、当該隣接点間距離が予め設定された距離閾値を超えている測定点から構成される第１測定点群を抽出し、当該第１測定点群における前記距離情報に基づいて側縁位置情報（左側縁推定線５０Ｌ、右側縁推定線５０Ｒ）を演算する。【選択図】図６
