PROBLEM TO BE SOLVED: To provide a travel control device for a slope work vehicle, which ensures safe and automatic travel in a slope.SOLUTION: A travel control device for a slope work vehicle includes an azimuth meter 1 for detecting a traveling direction of a mower, a vehicle speed meter 2 for detecting a travelling speed of the mower, and a wire drum capable of winding and feeding two wires independently. The travel control device is characterized by: including wire angle encoders 5a, 5b for detecting a feeding direction angle of the wire to the vehicle body, in each wire outlet of each wire drum including wire feeding amount detection units 6a, 6b for detecting each wire feeding amount in the wire drum including a wire fixing anchor fixed to both ends of the width of the slope to be worked on the tip of each wire and including a control unit 13 for grasping a relative position between the mower and both wire fixing anchors from a traveling direction of the mower and a feeding angle and a feeding amount of the two wires, and performing zigzag travel control of the mower along a work slope by winding and feeding both wires in synchronization with the travelling speed of the mower.COPYRIGHT: (C)2015,JPO&INPIT【課題】斜面で安全に自動走行させることが可能な斜面作業車両用走行制御装置を提供する。【解決手段】草刈機の進行方向を検出する方位計1と、草刈機の走行速度を検出する車速計2と、2本のワイヤを独立して巻き取り及び繰り出し可能なワイヤドラムと、を備え、各ワイヤドラムの各ワイヤ引き出し口には、車体に対するワイヤの繰り出し方向角度を検出するワイヤ角度エンコーダ5a、5bを備え、ワイヤドラムには、各ワイヤの繰り出し量を検出するワイヤ繰出量検出部6a、6bを備え、各ワイヤの先端には作業予定斜面の幅の両端部に固定するワイヤ固定アンカーを備え、草刈機の進行方位と、2本のワイヤの繰り出し角度と繰り出し量から、草刈機と両ワイヤ固定アンカーとの相対位置を把握し、草刈機の走行速度に同期して両ワイヤの巻き取り及び繰り出しを行うことで作業斜面に沿って草刈機のジグザグ走行制御を行う制御部13を備える。【選択図】図3
