Abstract
An autonomous work vehicle including a positioning information obtaining unit including a GNSS receiver acquiring a position of the autonomous work vehicle, a driving unit including a motor, a memory storing position coordinates used to establish an entry avoidance zone, and a control unit including a processor. The control unit is configured to function as a zone entry judgement unit determining whether the autonomous work vehicle has approached the entry avoidance zone, and a zone entry validation unit determining whether the determination by the zone entry judgement unit that the autonomous work vehicle has approached the entry avoidance zone is valid. When the zone entry judgement unit determines that the autonomous work vehicle has approached the entry avoidance zone, and the zone entry validation unit determines that the determination by the zone entry judgement unit is valid, the control unit controls the autonomous work vehicle to perform an avoidance maneuver.
