Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods require manual operation to set reference points for generating autonomous vehicle routes, leading to burdensome work in route generation.
Innovation Solution
A route generation method that sets a set angle and a reference point in the field to generate a target route autonomously, utilizing a route generation system and program to automate this process.
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 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 by using its own navigation system to generate route information.
Solution Approach 2:
The manual mechanical operation of driving the vehicle to specific locations and registering points is replaced by an automated electronic system that uses positioning devices, sensors, and computer processing to automatically acquire position information and generate the target route.
2Productivity
If manual driving is used to register reference points, then the route can be established, but the operator's workload increases
Solution Approach 1:
The work vehicle autonomously performs the function of point registration by using its onboard positioning system to automatically determine and record the reference start point and reference end point coordinates, eliminating the operator's manual involvement in this repetitive task.
Solution Approach 2:
The tedious task of manual point registration is extracted from the operator's duties and assigned to an automated system comprising positioning devices and control units, allowing the operator to focus on higher-level decision-making and monitoring tasks.

AI summary
A setting processing unit sets a set azimuth that is an angle with respect to a reference orientation, and sets a reference point at a predetermined location in a field. A generation processing unit generates a target route on the basis of the set azimuth and a reference line passing through the reference point.
