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.

摘要： A vehicle control system includes a first controller, a first communication unit, and a second controller and communication unit both on board a vehicle. The second controller is configured to generate first control signals for controlling the vehicle based at least in part on second control signals received by the second communication unit from the first communication unit. The first controller is configured to receive proximity signals relating to a geographic proximity between two or more designated transports. The transports are respective movements of material from respective first locations to respective second locations. The first controller is further configured to generate a control plan for the two or more transports based at least in part on the proximity signals, and generate the second control signals, for communication to the second controller for controlling completion of the two or more transports, based on the control plan.

摘要： To provide a road shoulder-detecting system which can accurately measure the orientation of a vehicle relative to a road shoulder and the distance to the road shoulder. The present invention includes road shoulder-detecting units to scan a road surface in front of a vehicle in the traveling direction of the vehicle and detect a road shoulder located on the road surface and a road shoulder-measuring device to measure the orientation of the vehicle relative to the road shoulder detected by the road shoulder-detecting units and the distance to the road shoulder; and the two road shoulder-detecting units are installed on the traveling direction side of the vehicle. The two road shoulder-detecting units are installed in a higher position than the upper ends of front wheels.

摘要： A construction machine control system for a construction machine that travels along a travel route, includes: a position detection unit that detects a position of the construction machine; a determination unit that determines whether an error in the position detected by the position detection unit is equal to or smaller than a predetermined error; a non-contact sensor that detects a position of an object around the construction machine; and a map information storage unit that extracts a detection result related to a vertical projection that protrudes vertically from a detection result of the non-contact sensor and stores the extracted detection result related to the vertical projection as map information when the determination unit determines that the error in the position detected by the position detection unit is equal to or smaller than the predetermined error.
