Abstract: A management control device controls multiple unmanned vehicles, including the overtaking of a vehicle using an opposite lane. First and second travel permission sections are set for an own vehicle and another vehicle in a stopped state located ahead of the own vehicle on a traveling lane. A path by which the own vehicle overtakes the other vehicle is generated to include a first transition section to change lanes from a traveling lane to an opposite lane, an overtaking section that connects to the first transition section. Also included is a second transition section that connects to the front end of the overtaking section and is for the own vehicle to return to the traveling lane. The section length of the second travel permission section being set in advance is thereby shortened.

The terminal-side control device includes: a remaining distance calculation unit that calculates a travel permission remaining distance on the basis of the present position of the own vehicle acquired from a position calculation device and the travel permission section; an upper limit speed calculation unit that calculates an upper limit speed of the own vehicle in the travel permission section on the basis of the travel permission remaining distance calculated by the remaining distance calculation unit; and a display control unit that causes a terminal side display device to output and present to the driver the upper limit speed calculated by the upper limit speed calculation unit and predetermined warning information corresponding to the upper limit speed.

Abstract: A traffic control system for allowing vehicles to travel unattended while maintaining their inter-vehicular distances without interfering with each other includes an onboard control apparatus mounted on the vehicles; and a traffic control apparatus which divides tracks for multiple vehicles into a plurality of sections and performs a blocking control to assign non-overlapping travelable sections to the multiple vehicles as a permitted travel section. The onboard control apparatus sets a travel permission request starting distance that is longer than a stoppable distance on the basis of the current speed of the vehicle and repeatedly transmits a travel permission request and current position information to the traffic control apparatus until the next travel permission is obtained when the remaining length of the permitted travel section has become shorter than the travel permission request starting distance in the advancing direction of the vehicle.

Abstract: Provided is a technology that, when an unmanned haulage vehicle and a manned haulage vehicle are allowed to exist together and are subjected to fleet operations management, can provide driving assistance to an operator of the manned vehicle by using control data similar to those to be transmitted to the unmanned haulage vehicle. To this end, the manned vehicle is provided with a terminal-side communication control unit, a control command value conversion unit and a control command value providing unit.

The control command value conversion unit converts contents of the control command value to perceivable information. The control command value providing unit provides the perceivable information to the operator.

Abstract: A fleet management server is connected to onboard terminal equipments mounted on plural haulage vehicles. The server includes an operation mode determination unit and operation mode switching unit. The determination unit determines whether or not an operation mode, in which segment setting processing is performed to set travel-permitted segments for the vehicles, respectively, needs switching between a bidirectional mode and a push mode. In the bidirectional mode, the processing is performed to send response information upon reception of request information from each onboard terminal equipment. In the push mode, a travel-permitted segment setting unit, without reception of such request information, performs the processing for one of the vehicles to set a new travel-permitted segment, and produces and transmits travel permission information indicating the new travel-permitted segment. The switching unit performs switching processing of the operation mode according to the results of the determination.

Abstract: Disclosed are a vehicle travel system and vehicle travel control method for guiding a haulage vehicle to a loading point without interference with obstacles. The vehicle travel system is provided with a direction input device (102), travel route calculating unit (1507) and vehicle control unit (205). Through the direction input device, an operator of a loading machine (10) inputs the direction of a body of a haulage vehicle (20-1) at a loading point (LP-L or LP-R). The travel route calculating unit calculates a travel route on which the haulage vehicle (20-1) is to be stopped in the inputted direction at the loading point (LP-L or LP-R). The vehicle control unit performs vehicle control to allow the haulage vehicle (20-1) to travel along and stop on the travel route.
