  • Publication number: 20150112537
    Abstract: Provided is a navigation system for autonomous dump trucks capable of preventing a dump truck from autonomously traveling on a carrying passage differing from the actual carrying passage even when the carrying passages for the dump truck have been altered. The navigation system is based on map data created by digitizing a map of roads on which the dump truck can travel. A control unit executes switching control between an autonomous mode to be selected when the autonomous traveling of the dump truck should be performed and a maneuver mode to be selected when the dump truck should travel according to an operator, based on version information of the map data used by the dump truck for the autonomous traveling and version information of master map data created by digitizing a map of the latest roads on which the dump truck can travel, managed by a control center.

  • Patent number: 6556913
    Abstract: It is an object of the invention to provide a more practical ACC system. During a travel of a vehicle, an image processor successively extracts geometric feature values of image patterns of a leading vehicle from image data successively outputted from a camera device mounted at the front of the vehicle. When a travel start detector detects a travel of the vehicle, a reference parameter value setting process section of a microcomputer sets a geometric feature value of an image pattern of the leading vehicle extracted at appropriate timing as a reference parameter value. Thereafter, each time a geometric feature value of the image pattern of the leading vehicle is extracted, a target driving force calculation process section calculates a target driving force Ttar for reducing any difference between the geometric feature value and the value set as the reference parameter value. A vehicle controller supplies to controllers a control command in accordance with the target driving force.
