    Abstract: A traffic control system is disclosed as having a locating device configured to generate a location signal indicative of a location of each of a plurality of machines. The traffic control system may also have an onboard controller configured to regulate operation of the plurality of machines based on the location signal, a communication device, and a worksite controller. The worksite controller may be configured to determine a first route for a first of the plurality of machines, and to determine if a first lane of the first route is blocked by a second of the plurality of machines. The worksite controller may also be configured to determine if a second lane of the first route intersects with a second route of the second of the plurality of machines, and to selectively grant permission for travel of the first of the plurality of machines through the second lane.

    Abstract: A mine management system includes generating unmanned vehicle traveling data including a target traveling route of an unmanned vehicle, acquiring unmanned vehicle current situation data at first time point, acquiring manned vehicle current situation data at the first time point, estimating a range in which the unmanned vehicle may be present at second time point based on the unmanned vehicle traveling data and the unmanned vehicle current situation data, estimating a position where a manned vehicle may be present at the second time point based on the manned vehicle current situation data, and deriving a risk level indicating a possibility of collision between the manned vehicle and the unmanned vehicle corresponding to the second time point at the first time point per position where the manned vehicle may be present based on estimation results of estimating the unmanned vehicle existence range and the manned vehicle existence position.

    Abstract: A system for zone passage control for a zone of an autonomously operating mobile object includes at least a set of detection units to detect at least one mobile object entering and/or exiting the zone, a set of identification units arranged to identify the mobile object entering and/or exiting the zone, and a central controller being arranged in operational connection with the set of the detection units and with the set of the identification units. An admissibility level for a mobile object to enter the zone is determined and a control signal to stop at least one autonomously operating mobile object existing in the zone is provided in response to the determined admissibility level being negative for the mobile object entered the zone.

    Abstract: A managing method of a mining machine includes: detecting a position of a landmark; and extending a first distance when a position of the landmark obtained in advance is present within a range of a second distance in a travel direction of the mining machine from a position, as a reference, where the mining machine reaches when the mining machine travels the first distance after the mining machine starts traveling by the dead reckoning navigation, when the mining machine travels in an unmanned state in a mine in which a plurality of the landmarks is located, the mining machine travels based on a detected self position and uses the dead reckoning navigation while correcting a current position of the mining machine based on a position of the landmark obtained in advance and a detected position of the landmark when the self position cannot be detected.

    Abstract: A work machine control system is configured to control a work machine that travels on a travel route and includes a position detection unit, a non-contact sensor, and a control unit. The position detection unit detects a position of the work machine. The non-contact sensor detects a position of an object around the work machine. The control unit extracts information on an object to be detected from a detection result of the position detection unit and a detection result of the non-contact sensor, and excludes the information on an object to be detected inside a mask region that is set so as to include a terrain change portion that is a portion in which a terrain changes by use of a machine among portions around the travel route.

    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: Automated excavating uses automated dozers and other earthmoving equipment to move material at a worksite. When such equipment is required to avoid a temporary obstruction, traverse between work slots, or traverse between work areas, a controller uses information from real-time sensors and contour maps to determine a new route to the destination. The controller also determines in real time whether the proposed route will keep the equipment on terrain with slopes that do not exceed a slope limit set for the mobile excavation machine. If not, the controller re-routes the machine to a new path over terrain with acceptable slopes.
