Abstract
A hauling vehicle includes a position detection device, a speed detection device, and a vehicle control device. The vehicle control device acquires a work content of the hauling vehicle corresponding to either hauling or standby based on the position of the hauling vehicle verified with the map information and detected by the position detection device and the speed of the hauling vehicle detected by the speed detection device, and calculates a work progression of a loading operation to the hauling vehicle. The vehicle control device also calculates a period from a predicted time at which the work progression exceeds a predetermined proportion until a predicted time at which the hauling vehicle starts acceleration based on the calculated work progression as an acceleration preparation time. The vehicle control device also drives the power generator to generate electricity during the acceleration preparation time based on the calculated acceleration preparation time.
