Hauling Vehicle and Vehicle Control System

An unmanned vehicle is a vehicle that drives an electric motor by electric power generated in a power generator to travel by driving of the electric motor and includes a position sensor that detects a position of the unmanned vehicle a speed sensor that detects a speed of the unmanned vehicle and a vehicle control device that controls the unmanned vehicle The vehicle control device calculates a work progression of a loading operation to the unmanned vehicle by a loading machine or a work progression of a preceding vehicle based on the position of the unmanned vehicle detected by the position sensor and the speed of the unmanned vehicle detected by the speed sensor calculates a period from a predicted time at which the calculated work progression exceeds a predetermined proportion until a predicted time at which the unmanned vehicle starts acceleration as an acceleration preparation time, and drives the power generator to generate electricity during the calculated acceleration preparation time.
