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: A vehicle peripheral obstacle notification system, used on a construction machine, detects a moving obstacle, gives composite display of the detected moving obstacle, and notifies a user thereof, the moving obstacle being at a location not appearing in a composite bird's-eye view obtained by onboard cameras acquiring images of the surroundings of the vehicle including an image immediately under the vehicle body. The system has a composite image formation part that extracts composite image formation areas from the surrounding images to compose a composite bird's-eye image. A moving obstacle is detected using the surrounding images and it is decided whether the detected position of the moving obstacle is inside or outside the composite image formation areas. If the detected position is determined to be outside the composite image formation areas, information about the detected position is extracted and an image thereof is output for superimposition onto the composite bird's-eye image.
