Abstract: A vehicle control system that makes it possible to ensure the safety and enhance the productivity at the same time is provided. An unmanned dump 10 receives positional information about a manned vehicle 20 by using infrastructure-to-vehicle communication 520 and infrastructure-to-infrastructure communication 510. In a case where an inter-vehicle distance X between the unmanned dump 10 and the manned vehicle 20 is equal to or shorter than a reference distance Y, the unmanned dump 10 decides whether or not vehicle-to-vehicle communication 550 is established between the unmanned dump 10 and the manned vehicle 20. In a case where it is decided that the vehicle-to-vehicle communication 550 is established, the upper limit of the travel speed of the unmanned dump 10 is set to a first speed V1, and in a case where it is decided that the vehicle-to-vehicle communication 550 is not established, the upper limit of the travel speed of the unmanned dump 10 is set to a second speed V2.

Abstract: A bird's eye view image is displayed to be recognized by an operator intuitively and precisely, irrespective of the displayed direction of the bird's eye view image. The display device has a plurality of cameras having optical axis directed obliquely downward to take images around a self-propelled industrial machine. A view point converting section converts the camera images to an upper view point to create bird's eye images, and an image composing section creates a composite bird's eye view image by composing respective bird's eye images around a symbol image of a dump truck. A direction superposing section superposes a forward direction indicator to indicate the forward direction of the dump truck on the composite bird's eye view image, and a monitor mounted in a cab of the dump truck displays the composite bird's eye image in an arbitral direction which is composited with the forward direction indicator.

The system includes an attitude detection sensor fixed on the body frame, a wheel rotational speed sensor, a loading status information acquiring unit, a correction amount setting unit, a velocity vector calculating unit, and a position calculating unit. The loading status information acquiring unit acquires loading status information indicating whether the body frame is in a loaded state or in an unloaded state . The correction amount setting unit calculates, based on the attitude information, a correction amount required for bringing detection axes in the loaded state into coincidence with corresponding detection axes in the unloaded state. The velocity vector calculating unit calculates the velocity vector of the haulage vehicle. The position calpulating unit calculates a position of the haulage vehicle by using the velocity vector.

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.
