  • Patent number: 10983515
    Abstract: A method of controlling a driving speed, which controls a working vehicle at a remote location to be driven on a route at an optical driving speed, is provided. The method includes: calculating terrain data based on a terrain scan image of the route acquired by a terrain scanner of the working vehicle; calculating the optimal driving speed according to the calculated terrain data; generating a driving control signal controlling the working vehicle to be driven on the route at the calculated optimal driving speed; calculating a vibration value of the working vehicle being driven on the route at the calculated optimal driving speed based on a sensing value acquired by a sensor of the working vehicle; adjusting the calculated optimal driving speed according to the calculated vibration value; and regenerating a driving control signal controlling the working vehicle to be driven on the route at the adjusted optimal driving speed.

  • Publication number: 20110044505
    Abstract: Provided are equipment operation safety monitoring system and method and computer-readable medium having a program recorded thereon, the program allowing a computer to execute the method. The equipment operation safety monitoring system includes an image input unit, an integrated image generation unit, a guideline generation unit, and an image output unit. The image input unit is mounted on heavy equipment and inputs a plurality of images acquired by photographing partitioned areas in all the directions around the heavy equipment. The integrated image generation unit generates an integrated image including the areas in all the directions around the heavy equipment by using the plurality of the images. The guideline generation unit generates a guideline indicating a position separated by a predetermined distance from the heavy equipment. The image output unit illustrates the guideline on the integrated image and outputs the integrated image.
