Zusammenfassung: | To provide a work vehicle which can safely travel by properly controlling functions about automatic steering and manual operation.SOLUTION: A work vehicle comprises: a steering device which controls the travel direction of a traveling vehicle body; a positioning device which measures the self-position of the traveling vehicle body; and a control unit which includes a work mode control of actuating a brake according to a control amount of the steering device, a travel mode control of not actuating the brake even when the steering device is operated and an automatic steering mode control of controlling the steering device so as to travel along a preset travel path. The work vehicle comprises: a mode change-over switch which switches between the work mode control and the travel mode control; and an automatic steering turn-on/off switch which switches turn-on/off of the automatic steering mode control. The control unit makes the turn-on operation of the automatic steering turn-on/off switch effective only when the mode change-over switch is switched to the work mode control.SELECTED DRAWING: Figure 5
【課題】自動操舵と手動操作に関する機能を適切に制御して安全に走行できる作業車両を提供する。【解決手段】走行車体の進行方向を操作する操舵装置と、走行車体の自己位置を測定する測位装置と、操舵装置の操作量に応じてブレーキが作動する作業モード制御、操舵装置を操作してもブレーキが作動しない走行モード制御および、予め設定された走行経路に沿って走行するように操舵装置を制御する自動操舵モード制御を有する制御部とを備えた作業車両であって、作業モード制御と走行モード制御とを切り替えるモード切替スイッチと、自動操舵モード制御の入り切りを切り替える自動操舵入り切りスイッチとを備え、制御部はモード切替スイッチが作業モード制御に切り替えられている場合に限り、自動操舵入り切りスイッチの入り操作を有効化する。【選択図】図5 |
