Abstract

A hybrid type work vehicle includes a power source, a traveling unit, a hydraulic work unit, an accelerator pedal, a brake pedal, an operation lever device, and a control apparatus. The control apparatus is configured such that when the current operation state is determined to be that of an excavation work which is a combined operation of the traveling unit and the hydraulic work unit and the output power limitation signal is outputted, the control apparatus limits the output power of the traveling unit. The control apparatus is also configured to decrease the tilting angle of the hydraulic pump, such that a ratio between the output power of the traveling unit and the output power of the hydraulic work unit is maintained at a preset ratio.
