摘要： An unmanned vehicle 20 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 240 that detects a position of the unmanned vehicle 20, a speed sensor 250 that detects a speed of the unmanned vehicle 20, and a vehicle control device 220 that controls the unmanned vehicle 20. The vehicle control device 220 calculates a work progression of a loading operation to the unmanned vehicle 20 by a loading machine 30 or a work progression of a preceding vehicle based on the position of the unmanned vehicle 20 detected by the position sensor 240 and the speed of the unmanned vehicle 20 detected by the speed sensor 250, 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 20 starts acceleration as an acceleration preparation time, and drives the power generator to generate electricity during the calculated acceleration preparation time.

摘要： Provided is a control system for hauling vehicle capable of suppressing slippage of a hauling vehicle while suppressing a decrease in travel speed of the hauling vehicle. A control system for hauling vehicle causes a hauling vehicle 100 to travel based on a control target including a target route. The control system generates a control target based on the map information, which includes information on the travel path WP along which the hauling vehicle 100 travels and information on a plurality of travel sections TS obtained by dividing the travel path WP; the loading quantity on the hauling vehicle 100 in each travel section TS; and a slippage index indicating the slipperiness of the travel path WP in each travel section TS. If the slippage index SI of at least one travel section TS is less than the predetermined threshold, the control system sets a larger turning radius of the turning route included in the target route for that travel section TS than for the case where the slippage index is equal to or greater than the predetermined threshold.
