<p>A traveling control device for a hydraulically-driven vehicle includes: a traveling hydraulic motor driven by oil delivered from a hydraulic pump; a speed-reducing mechanism with an adjustable speed-reduction ratio, that slows down rotation of the hydraulic motor and transmits the slowed rotation to wheels; a pressure oil control device that controls a flow of pressure oil from the hydraulic pump to the hydraulic motor in correspondence to an extent to which a traveling pedal is operated; a speed-reduction ratio detection device that detects the speed-reduction ratio at the speed-reducing mechanism; and an acceleration limiting device that restricts accelerating operation of the hydraulic motor achieved in response to an operation of the traveling pedal, when an acceleration-limiting condition, that is, the speed-reduction ratio detected by the speed-reduction ratio detection device is equal to or greater than a predetermined value, is met.</p> |
