PROBLEM TO BE SOLVED: To provide a controller for a working vehicle, capable of lessening the influence of wide turning by reflecting the result of a precise prior judgement as the wide turning on automatic turning control.SOLUTION: The controller for the working vehicle is equipped with a controlling treating part 21 for controlling the operation of the working vehicle by a prescribed standard position n of the turning process based on the turned distance of traveling wheels under turning travel. The controlling treating part 21 is constituted so that when the difference in the rotational speeds of the right and left traveling wheels is smaller than a prescribed standard value, the control of the operation of the working vehicle may be carried out based on a corrected standard position obtained by subjecting the standard position n to a prescribed correction treatment.COPYRIGHT: (C)2008,JPO&INPIT【課題】大廻り旋回についての確実な事前判定により、自動旋回制御に反映して大廻り旋回の影響を小さく抑えることができる作業車用制御装置を提供する。【解決手段】作業車用制御装置は、旋回走行中の走行車輪の転動量に基づいて旋回行程の所定の基準位置nによる作業機動作制御を行う制御処理部21を備えて構成され、上記制御処理部21は、走行車輪の左右回転速度差が所定の基準値より小なる場合に、上記基準位置nを所定の補正処理した補正基準位置により作業機動作制御を行うように構成したものである。【選択図】図3
