Industrial vehicle and power control method for the same

摘要

The present invention provides an industrial vehicle having a hybrid system capable of readily controlling a distribution of power generated by an engine (7) and power generated by an electric motor, and a method of controlling; the power of the same. A hybrid industrial vehicle includes an engine (7) for supplying power to one of a running unit (3) and a loading-and-unloading unit (5); a first motor (9) for supplying power to one of the running unit (3) and the loading-and-unloading unit (5); a second motor (11) for supplying power to the running unit (3); a required-power calculating unit (41) for calculating running power, and loading-and-unloading power; a clutch unit (17) for controlling the power transmitted from the engine (7) to the running unit (3); and a power-distribution calculating unit (43) for selecting a destination to be supplied with power form the engine (7) and the first motor (9) based on the control status of the clutch unit (17), and for calculating a distribution of power which the engine (7), the first motor (9), and the second motor (11) supply based on the calculated running power and loading-and-unloading power.
