Operation Vehicle Route Switching for Automatic Travel Between Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic travel systems for operation vehicles cannot automatically travel between operation regions, leading to decreased efficiency as manual intervention is required for movement between defined operation regions, such as fields and farm roads.
Innovation Solution
Incorporating a path generation unit that creates operation paths within regions and movement paths connecting them, along with an automatic travel control unit that temporarily stops the vehicle to switch from an internal path to an external path, enabling the vehicle to automatically travel between regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the system defines operation regions and generates target travel paths only within each region, then automatic travel control can be achieved inside operation regions, but the operation vehicle cannot automatically travel outside operation regions requiring manual intervention
Solution Approach 1:
The target travel path generation unit is enhanced to perform multiple functions: generating operation paths within operation regions and movement paths outside operation regions. This multi-functional capability allows the system to handle both automated operation and automated movement between regions, eliminating the need for manual intervention while maintaining comprehensive path coverage.
2Productivity
If the system generates separate operation paths for each operation region, then automatic travel can be achieved within regions, but movement between regions requires manual operation reducing efficiency
Solution Approach 1:
The system merges the generation of operation paths and movement paths into a unified target travel path. By combining these path types and enabling automatic transition between them, the system eliminates manual intervention time and continuously maintains automated travel control, thereby improving overall productivity and reducing time loss.
3Speed
If the automatic travel control unit switches traveling paths from inside to outside operation regions without temporary stop, then movement efficiency is maintained, but safety may be compromised during path switching
Solution Approach 1:
The automatic travel control unit performs a temporary stop before switching from operation paths to movement paths. This preliminary action allows the system to confirm the safety of path switching in advance, ensuring that the transition occurs only when safe, while maintaining efficient automated movement by resuming travel immediately after confirmation.

AI summary
The present invention is provided with a path generation unit that generates an operation path for each of a plurality of operation regions, and an automatic travel control unit that causes an operation vehicle to travel automatically along the operation path generated by the path generation unit. The path generation unit is configured to be able to generate a movement path that connects different operation regions by causing the operation vehicle to travel outside the operation regions. The automatic travel control unit is configured to temporarily stop the operation vehicle before switching the traveling path on which the operation vehicle travels automatically from a path inside the operation regions to a path outside the operation regions, and in response to the temporary stop state being terminated, cause the operation vehicle to travel automatically by switching the traveling path to a path outside the operation regions.
