A tire management system assigns work to each of a plurality of vehicles and manages a loaded state of a tire mounted on each of the vehicles that perform the assigned work. The tire management system includes: an overload vehicle detection unit configured to detect an overloaded vehicle in which a tire load of the work assigned to each of the vehicles exceeds a predetermined tire load set in the tire itself of the vehicle; and a work contents changing processing unit configured to perform, when the overloaded vehicle is detected, processing of changing work contents of the overloaded vehicle such that the tire load of the overloaded vehicle becomes equal to or less than the predetermined tire load.

A management system of a work site includes an image data acquisition unit that acquires image data of an unmanned vehicle stopped at the work site due to generation of a trouble, the image data being imaged by an imaging device mounted in a movable body.

Management system of work site and management method of work site

A management system of a work site includes a guidance unit which outputs, to a manned vehicle of a work site, guidance data for guiding the manned vehicle to an unmanned vehicle stopped due to occurrence of an abnormality at the work site.

A tire abnormality management system assigns work to each of a plurality of vehicles and manages an abnormal state of a tire mounted on each of the vehicles that perform the assigned work. The tire abnormality management system includes: a tire sensor configured to detect a tire pressure and/or a tire temperature of each of the vehicles; a grouping processing unit configured to group vehicles, in which a tire load of the work assigned to each of the vehicles is within a predetermined range, into a vehicle group; and a tire abnormal vehicle identifying unit configured to identify, among the grouped vehicles, a vehicle with an abnormal tire based on the tire pressure or the tire temperature detected by the tire sensor.

The tire management system includes: an overload vehicle detection unit configured to detect an overload vehicle in which a tire load of the work assigned to each of the vehicles exceeds a predetermined tire load set in the tire itself of the vehicle; and a work contents changing processing unit configured to perform, when the overload vehicle is detected, processing of changing work contents of the overload vehicle such that the tire load of the overload vehicle becomes equal to or less than the predetermined tire load.

A fuel supply system includes: a fuel supply facility capable of supplying fuel; an earth-moving machine capable of traveling toward the fuel supply facility; and a control apparatus that acquires execution permission information indicating whether or not fuel can be supplied to the earth-moving machine, and is capable of executing control based on the acquired execution permission information, wherein when the control apparatus determines that fuel cannot be supplied to the earth-moving machine based on the execution permission information at a time of supplying the fuel to the earth-moving machine, the control apparatus executes entry restriction control for restricting an entry to the fuel supply facility by the earth-moving machine.

A transport vehicle equipped with a current collector, includes: a vessel to load a load; a current collector that extends to receive electric power from an overhead line and contracts and retracts so as to be disposed below the vessel; and a vehicle body that rotationally drives driving wheels by at least one of the electric power from the current collector and a self-propelled driving source and on which the vessel is placed.

Transport vehicle equipped with current collector

A transport vehicle equipped with a current collector, includes: a vessel to load a load; a current collector that extends to receive electric power from an overhead line and contracts and retracts so as to be disposed away from the overhead line; and a vehicle body that rotationally drives driving wheels by at least one of the electric power from the current collector and a self-propelled driving source and on which the vessel is placed; a pantograph position detector that detects a relative position of the current collector and the overhead line; and a control device that controls a driving direction of the vehicle body or gives an instruction of information with which a direction in which the vehicle body is to be operated can be recognized, so that the relative position is brought to a position where the current collector and the overhead line are connected.

Guiding speed is increased while an unmanned vehicle is prevented from straying from a travel passage width, to improve the work efficiency. Target speed of the unmanned vehicle increases as a distance between a current position of the unmanned vehicle and a guidable borderline increases, and the target speed of the unmanned vehicle decreases as the distance between the current position of the unmanned vehicle and a guidable borderline decreases. The unmanned vehicle travels, along a travel path having adjacent inbound/outbound lanes, in a direction opposite to a direction of a vehicle on an oncoming lane. If it is determined that the vehicle traveling along the oncoming lane is approaching the unmanned vehicle, then the target speed of the unmanned vehicle is reduced, whereby the unmanned vehicle is caused to travel at a low guiding speed.

Guided control device for unmanned vehicle

Leveling operation can be effectively performed at a discharge site without increasing a cost of vehicles, and a running course can be easily generated in a short time and at a low-cost. Based on each of measured position data of a survey lineof a discharge site, a normal line Lc normal to the survey lineis obtained, a target discharge position' is positioned at a prescribed distance away from the survey linein an inward direction of the discharge sitebased on the normal line Lc, and then data of a running coursein which a reference approach directionto approach the target discharge position&#x2032; is a direction normal to the survey lineare generated.

Control device and method for guided travel of unmanned vehicle

A restricted area () is created based on positional information of a manned vehicle () traveling one of outward/return lanes (), and a detour course () is created based on information of the restricted area (). Information on the detour course () is provided to the unmanned vehicles () and the manned vehicle (). Based on the positional information of the unmanned vehicles () which proceed towards each other from the opposite directions with the restricted area () therebetween, the unmanned vehicle () on the lane () which is the opposite side of the restricted area () is blocked at a block position (B) and at the same time a travel permission command for permitting traveling the detour course () is issued to the unmanned vehicle () traveling the lane () on the restricted area side so that the unmanned vehicle () travels the detour course ().

Travel control device and method for vehicles

A running control unit receives fuel residual quantity information from each vehicle by radio to deduce a period of time, during which the vehicle can operate, on the basis of the information and vehicle fuel consumption rate information in a database. Also, the running control unit reads production information, production planning information, and oil station information from a data base to calculate are fueling permissible number, for which refueling may be done simultaneously at the oil station, on the basis of these information and information of the number of the vehicles. Then the running control unit makes up refueling schedules for a plurality of vehicles on the basis of an operating period of time for each vehicle and the refueling permissible number.

Maintenance scheduling apparatus and method therefor

This travel control apparatus for vehicles is provided with a fellow vehicle judgement device adapted to judge whether a fellow vehicle coming close to a subject vehicle traveling on a track is present or absent, and a device for shifting a traveling course of the subject vehicle when a judgement that a fellow vehicle coming close to the subject vehicle is present is given by the fellow vehicle judgement device, so as to have the subject vehicle traveling along a solo traveling course set on the track travel along a course set close to a shoulder of the track.
