WORKING VEHICLE AND METHOD FOR CONTROLLING WORKING VEHICLE

摘要

In the present invention, when a target upper limit velocity is within a normal velocity range, an upper limit velocity control unit controls a lower limit of a motor capacity in accordance with the target upper limit velocity by means of a motor capacity control unit. When the target upper limit velocity is within a low-velocity range, the upper limit velocity control unit controls the upper limit of a pilot pressure in accordance with the target upper limit velocity by means of a pilot pressure control valve. Also, when the target upper limit velocity is within the low-velocity range, the upper limit velocity control unit controls the pilot pressure control valve in a manner so that the greater a driving circuit pressure, the greater the upper limit of the pilot pressure.
