Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An autonomous work vehicle adapted to be guided by a signal emitted by a wire disposed at a working area, the autonomous work vehicle comprising: a control unit comprising a processor; and at least one sensor, detecting the signal emitted by the wire, wherein the wire includes an area wire surrounding the working area, and a shortcut wire disposed inside the working area, and 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, wherein 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 cross over the detected shortcut wire such that a polarity of the signal detected by the at least one sensor changes to an opposite polarity, and the control unit controls the autonomous work vehicle to trace the shortcut wire at a predetermined variable distance while maintaining the opposite polarity. 2. The autonomous work vehicle according to claim 1 , wherein the control unit identifies an area among a plurality of areas in the working area in which the autonomous work vehicle is located in based on a signal type and a polarity of the wire detected by the at least one sensor, and determines a trace direction of the autonomous work vehicle based on the signal type and the polarity of the wire detected by the at least one sensor. 3. The autonomous work vehicle according to claim 2 , wherein the control unit identifies the area among the plurality of areas in the working area in which the autonomous work vehicle is located in, based on a signal type and a polarity of the area wire and a signal type and a polarity of the shortcut wire detected by the at least one sensor, and determines a trace direction of the autonomous work vehicle based on the signal types and the polarities of the area wire and the shortcut wire detected by the at least one sensor. 4. The autonomous work vehicle according to claim 3 , wherein the at least one sensor includes a first, second, and third sensor. 5. The autonomous work vehicle according to claim 1 , wherein when the at least one sensor detects the area wire while the autonomous work vehicle is tracing the shortcut wire at a predetermined variable distance, the control unit controls the autonomous work vehicle to trace on top the shortcut wire.
