Latest Patents

One of Toriyama's latest patents is a working machine that includes a design data obtainment unit, a topography measuring device, and a controller. The controller extracts peripheral area shape data from the design data in the construction-site coordinate system. It maps similar shape portions between the extracted peripheral area shape data and the current topography data in the current topography coordinate system. The controller calculates a coordinate transformation matrix to transform from the current topography coordinate system to the construction-site coordinate system, minimizing the difference in coordinate values of the mapped shape portions. It also transforms the self-position and posture of the working machine and the current topography data from coordinates in the current topography coordinate system to coordinates in the construction-site coordinate system using the calculated coordinate transformation matrix.

Another notable patent involves a controller mounted on a work machine that calculates a target carried load representing a target value for a carried load based on the loadage of a transportation machine when the loadage is changed. The controller calculates a minimum integration load value depending on the magnitude of the calculated target carried load. It also calculates the loadage by integrating the carried load when it is determined that a work implement has performed a loading operation on the transportation machine, provided that the calculated carried load is equal to or larger than the minimum integration load value.
