  • Patent number: 10126752
    Abstract: A travel route automatic selection system for a work machine includes a travel route search unit that searches a travel route satisfying a condition that the work machine can enter from a current position for preparing entry only by forward movement along an entry route formed so that the work machine enters at an entry position in a same direction as a traveling direction when the work machine travels the travel route, at an entry position positioned between a travel route start position and a work start position, from a predetermined travel route corresponding to each of the one or a plurality of work target zones, by determining whether the condition is satisfied based on at least the travel route part of the predetermined distance from the travel route start position at least between the travel route start position and the work start position of the predetermined travel route.

  • Patent number: 10120382
    Abstract: An entry availability determination system including a detector that detects a current position of a work machine that performs predetermined work while traveling a work target zone along a predetermined travel route; and a determination information generation unit that generates determination information indicating whether entry is possible by determining whether the work machine can enter from a current position for preparing entry of the work machine only by forward movement along an entry route formed so that the work machine enters at an entry position in a same direction as a traveling direction when the work machine travels the travel route, at the entry position positioned on an opposite side of the traveling direction of the work machine with respect to a work complete position or a work incomplete position on the travel route, when the work machine gets out of the travel route.

  • Patent number: 10114377
    Abstract: A travel route generation system of generating a travel route of a work machine that performs predetermined work while traveling a route formed by linking ends of at least a plurality of substantially parallel routes through inversion routes in a work target zone, the ends being positioned at or near intersections of the routes and the periphery of the work target zone, the system including a zone setting unit that sets a periphery of the work target zone and a periphery of an entry prohibited zone outside of the work target zone; and a route generation unit that selects, for each of the inversion routes, an inside inversion route, not an outside inversion route, according to a positional relationship between the periphery of the work target zone and the periphery of the entry prohibited zone, wherein the inside inversion route is selected as the travel route.

  • Patent number: 8954216
    Abstract: To provide a work machine that can make minimum passes over a target area without leaving any tasks with flexible steering operations. A controller 10 mounted on a motor-driven lawn mower 1 determines intersections between a contour service path and a pair of straight service paths that are adjacent to each other in which the motor-driven lawn mower 1 travels along the straight service paths in opposite directions, and sets (records) a turning behavior including backward movement of the motor-driven lawn mower connecting the adjacent intersections in a configuration file. The information recorded in the configuration file is read during the operation to move the motor-driven lawn mower along the contour service path 50 and the straight service paths on anywhere other than the aforementioned intersections and to turn in accordance with the turning behavior when the motor-driven lawn mower reaches one of the intersections.
