Abstract:
1. An industrial vehicle comprising: an engine configured to supply power to one of a running unit for running and a loading-and-unloading unit for loading and unloading; a first motor configured to selectively supply power to one of the running unit and the loading-and-unloading unit; a second motor configured to supply power to the running unit; a required-power calculating unit configured to calculate running power required by the running unit, and loading-and-unloading power required by the loading-and-unloading unit; a clutch unit configured to control the power transmitted from both the engine and the first motor to the running unit; and a power-distribution calculating unit configured to select either the running unit or the loading-and-unloading unit as a destination to be supplied with power from the engine and the first motor based on the control status of the clutch unit and to calculate a distribution of power which the engine, the first motor, and the second motor supply based on the calculated running power and loading-and-unloading power, wherein the power-distribution calculating unit calculates a distribution of power to be supplied from the engine, the first motor, and the second motor to the running unit based on the calculated running power in a case where the running unit is selected as the destination, and wherein the power-distribution calculating unit calculates a distribution of power to be supplied from the engine and the first motor to the loading-and-unloading unit based on the calculated loading-and-unloading power in a case where the loading-and-unloading unit is selected as the destination.
