ROAD SURFACE STATUS ARITHMETIC UNIT AND ROAD SURFACE MANAGEMENT SYSTEM FOR MINE
To provide a road surface status arithmetic unit and a road surface management system for mine which estimates the irregularity on a bypassed road surface.SOLUTION: A travel road surface irregularity level on a road surface on which a work vehicle has actually traveled is computed based on vehicle positional information and vehicle body vibration information measured by a work vehicle while traveling; it is determined whether the work vehicle is bypassing by comparing the position of an own vehicle with a reference track map; when the vehicle bypassed, a bypass start point and a bypass completion point are computed to determine whether the work vehicle has bypassed from the reference track; a higher level than a travel road surface irregularity level is assigned as a bypass road surface irregularity level in a bypass segment which is the reference track between the bypass start point and the bypass completion point; and the bypass road surface irregularity level and the travel road surface irregularity level are synthesized to generate a road surface irregularity map.SELECTED DRAWING: Figure 5
【課題】迂回された路面の凹凸を推定する路面状況演算装置及び鉱山の路面管理システムを提供する。【解決手段】作業車両が走行中に測定した車両位置情報及び車体振動情報に基づいて、作業車両が実際に走行した路面の走行路面凹凸レベルを演算し、自車両の位置と基準走行路地図を比較することにより、作業車両が迂回しているかを判定し、迂回時に迂回開始点と迂回終了点とを演算し、作業車両が基準走行路から迂回したか否かを判定し、迂回開始点と迂回終了点との間の基準走行路である迂回区間の迂回路面凹凸レベルとして、走行路面凹凸レベルよりも高いレベルを割り当て迂回路面凹凸レベル及び走行路面凹凸レベルを合成して路面凹凸地図を生成する。【選択図】図５
