Abstract
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 vehicleto 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 vehicletravels and information on a plurality of travel sections TS obtained by dividing the travel path WP; the loading quantity on the hauling vehiclein 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.
