Problem to be solved: to prevent the work from being accidentally interrupted during work running or restraining or avoiding the automatic rise to the non working height position from the work height position of the work device linked with the start of rotation of the working vehicle.In the control system for working vehiclesControl unitBased on the measurement information from the position measuring device 70 and the working location information, it is determined whether the current position of the vehicle body is an unworking area or a working area.If the current position of the vehicle body is an unworking area,As the turn start detector S6 detects the start of rotation of the vehicleThe lifting and lowering control function is executed by the elevating drive unit 43 to increase the working device from the working height position to the non working height position.If the current position of the vehicle body is the working area,The swing up prohibition processing prohibiting execution of the swing rise control function is performed.Diagram【課題】作業車両の旋回開始に連動した作業装置の作業高さ位置から非作業高さ位置への自動上昇を適正に行えるようにして、作業走行中に作業が不測に中断される虞を抑制又は回避できるようにする。【解決手段】作業車両用の制御システムにおいて、制御ユニット４６は、位置測定器７０からの測定情報と作業地情報とに基づいて車体の現在位置が非作業領域か作業領域かを判定し、車体の現在位置が非作業領域である場合は、旋回開始検出器Ｓ６にて車体の旋回開始が検出されるのに伴って、昇降駆動ユニット４３にて作業装置を作業高さ位置から非作業高さ位置まで上昇させる旋回上昇制御機能を実行し、車体の現在位置が作業領域である場合は、旋回上昇制御機能の実行を禁止する旋回上昇禁止処理を行う。【選択図】図４
