Abstract: The hybrid type work vehicle includes: a traveling unit having a traveling electric motor; a hydraulic work unit having a hydraulic pump; and a control apparatus having an operation determination section configured to input the operation amount of an operation lever device, the depression amount of an accelerator pedal and a brake pedal, and a vehicle speed and to determine the current operation state of the vehicle, and a power computation section configured to input the output value of an engine and the output value of a power storage device and to calculate and control the power of the traveling unit and the power of the hydraulic work unit. When the operation determination section determines that the current vehicle operation state is that of an excavation work which is a combined operation of the traveling unit and the hydraulic work unit, the power computation section calculates and controls the output power of the traveling unit and the output power of the hydraulic work unit such that the sum total of the output value of the engine and the output value of the power storage device is distributed in a preset ratio.
