Industrial vehicle and power control method for the same
Abstract:
An industrial vehicle having a hybrid system controls a distribution of power generated by an engine and power generated by an electric motor. The vehicle includes an engine for supplying power to one of a running unit and a loading-and-unloading unit; a first motor for supplying power to one of the running unit and the loading-and-unloading unit; a second motor for supplying power to the running unit; a required-power calculating unit for calculating running power, and loading-and-unloading power; a clutch unit for controlling the power transmitted from the engine to the running unit; and a power-distribution calculating unit for selecting a destination to be supplied with power from the engine and the first motor based on the control status of the clutch unit, and for calculating a distribution of power which the engine, the first motor, and the second motor supply based on the calculating running power and loading-and-unloading power.
