Abstract: An autonomous work vehicle is adapted to be guided by a signal emitted by a wire disposed at a working area. The autonomous work vehicle includes a control unit comprising a processor, and at least one sensor detecting the signal emitted by the wire. The wire includes an area wire surrounding the working area, and a shortcut wire disposed inside the working area. When the at least one sensor detects the shortcut wire while the autonomous work vehicle is tracing the area wire at a predetermined variable distance, the control unit is configured to control the autonomous work vehicle to trace the shortcut wire at a predetermined variable distance.

Abstract: The autonomous working machine including: a magnetic field detection part for detecting a magnetic field generated by the energization to the area wire; a storage part for storing a reference value of the magnetic field detection by the magnetic field detection part; a control part for controlling a traveling route based on the reference value stored in the storage part and the magnetic field detected by the magnetic field detection means; and an input part for receiving a selection of a first reference value used in a case where the area wire is installed at a first distance from the ground or a second reference value used in a case where the area wire is installed at a second distance from the ground, wherein the control part controls a traveling route based on the first reference value or the second reference value selected by the input part.
