Field Route Generation Using Azimuth and Reference Point Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for generating autonomous routes for work vehicles in fields require manual operation to set reference points, making the process burdensome and inefficient.
Innovation Solution
A route generation method that sets a set angle relative to a reference orientation and designates a reference point in the field, allowing for the automatic generation of a target route based on this angle and a reference line passing through the point.

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 position information using onboard positioning devices (GPS, inertial sensors, etc.) to determine the reference start point and reference end point, eliminating the need for manual driving and point registration. The vehicle serves itself in acquiring the necessary positioning data for route generation.
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 system that uses satellite signals, inertial sensors, and onboard computers to automatically determine and register the reference points.
2Productivity
If manual driving is used to register reference points, then the target route can be generated, but the operation complexity increases
Solution Approach 1:
The system automatically performs all operations needed for route generation including position acquisition, point registration, and route calculation without requiring the operator to manually drive the vehicle or interact with the registration system, thereby reducing operational complexity while maintaining high productivity.
Solution Approach 2:
The system uses copied position information from the vehicle's onboard positioning system to create the reference points and generate the route, eliminating the need for direct manual intervention in the point registration process.

AI summary
[Problem] To provide a route generation method, a route generation system, and a route generation program capable of improving workability of work to generate a target route on which a work vehicle travels autonomously in a field. [Solution] A setting processing unit 713 sets a set azimuth d1 that is an angle with respect to a reference orientation, and sets a reference point at a predetermined location in a field F. A generation processing unit 714 generates a target route R on the basis of the set azimuth d1 and a reference line L1 passing through the reference point.
