Title:
AUTOMATIC TRAVEL SYSTEM FOR WORK VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/006322
Kind Code:
A1
Abstract:
An automatic travel system for a work vehicle (1) has an automatic travel control unit (23F) that causes a work vehicle, which is provided with an obstacle detection unit (80) that detects obstacles, to travel automatically. The obstacle detection unit (80) includes imaging units (81-84) and active sensors (86-88). When the obstacle detection unit (80) detects an obstacle based on information from the imaging units (81-84), and the separation distance from the obstacle is acquired based on information from the active sensors (86-88), the automatic travel control unit (23F) executes a first collision avoidance control for avoiding a collision between the work vehicle and the obstacle, on the basis of the separation distance from the obstacle acquired based on the information from the active sensors (86-88).
