Work Vehicle Route Generation with Mode-Based Field Reference Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for generating autonomous routes for work vehicles in fields require manual operator intervention to set reference points, making the process burdensome and inefficient.
Innovation Solution
A route generation method and system that identifies and utilizes multiple route generation modes based on predetermined reference points, allowing for autonomous route generation without manual registration of start and end points, using a setting processing unit and generation processing unit to create target routes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual driving is used to acquire reference start point and reference end point, then the target route can be generated, but the work to generate the target route becomes burdensome
Solution Approach 1:
The work vehicle automatically acquires its own reference start point and reference end point through its positioning function during autonomous travel, eliminating the need for manual operator intervention to set these points. The vehicle serves itself by using its own travel data to generate the target route.
Solution Approach 2:
The manual mechanical operation of driving the vehicle to specific locations and manually registering points is replaced by an automated electronic positioning and data processing system that automatically captures coordinates and generates the route.
2Manufacturing precision
If multiple reference points are manually registered, then the target route can be generated with higher precision, but the operation complexity increases
Solution Approach 1:
The system automatically determines the necessary reference points based on the work vehicle's own travel trajectory, eliminating the need for operators to manually plan and register multiple reference points. The vehicle's autonomous travel path provides the precision data needed without increasing operational complexity.

AI summary
A setting processing unit identifies any route generation mode of plural route generation modes, in each of which a target route is generated on the basis of a reference point that is set at a predetermined location in a field. Then, a generation processing unit generates the target route in the identified route generation mode.
