Autonomous Route Linking for Aligned Work Vehicle Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous travel systems for work vehicles face challenges in efficiently managing and aligning multiple travel routes within the same field, requiring manual adjustments and separate management of routes with turning and without turning, which complicates the creation and switching processes.
Innovation Solution
An autonomous travel system incorporating a first and second travel route creation unit, an interlocking route creation unit, a storage unit, a route selection unit, and a travel control unit, which allows for the automatic creation and alignment of travel routes with overlapping straight routes, enabling efficient management and switching between routes without manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple travel routes are created separately in the same field, then each route can be optimized for specific work requirements, but manual adjustment of route positions becomes necessary and management becomes complicated
Solution Approach 1:
The patent merges the management of multiple travel routes by establishing hierarchical relationships between parent routes and child routes. Child routes inherit positional parameters from the parent route, automatically aligning their straight route positions without manual adjustment. This combining approach simplifies route management while maintaining the ability to optimize individual routes for specific work requirements.
Solution Approach 2:
The system performs preliminary action by pre-defining parent routes with optimal positions before creating child routes. When child routes are generated, they automatically inherit the parent's positional parameters, eliminating the need for subsequent manual position adjustments. This preliminary setup streamlines the overall route creation and management process.
2Ease of operation
If travel routes are created independently without interlocking, then each route can be created flexibly, but position alignment between routes requires manual adjustment
Solution Approach 1:
The patent implements feedback mechanisms where child routes automatically receive positional information from parent routes. This feedback loop ensures that when a parent route is created or modified, all associated child routes automatically align their straight route positions with the parent, maintaining precision without manual intervention while preserving creation flexibility.
Solution Approach 2:
The parent route serves multiple functions: it acts as a standalone travel route and simultaneously serves as a template for generating child routes. This multi-functionality allows the parent route's positional parameters to be universally applied to all child routes, ensuring automatic position alignment while maintaining ease of route creation.
3Adaptability or versatility
If separate route creation processes are used for routes with and without turning, then each route type can be optimized, but the creation process becomes more tedious and time-consuming
Solution Approach 1:
The patent segments the route creation process into parent route creation and child route generation. The parent route captures common positional parameters, while child routes inherit these parameters and can be quickly generated with minimal additional input. This segmentation maintains the ability to optimize for different route types while dramatically improving creation efficiency through automated inheritance.
Solution Approach 2:
The system uses copying by allowing child routes to inherit positional parameters from the parent route. Instead of recreating position information for each route type, the system copies the parent's positional data to child routes, automatically aligning them. This copying mechanism preserves route type optimization capabilities while reducing the tedium and time of route creation.

AI summary
An autonomous travel system equipped with a first travel route creation unit, a second travel route creation unit, a linked route creation unit, and a storage unit. The first travel route creation unit is capable of creating a first travel route. The second travel route creation unit is capable of creating a second travel route. The linked route creation unit has a function for creating the second travel route in conjunction with the creation of the first travel route by the first travel route creation unit and/or a function for creating the first travel route in conjunction with the creation of the second travel route by the second travel route creation unit. The storage unit stores, in association with each other, the travel route created by the first travel route creation unit or the second travel route creation unit, and the travel route created by the linked route creation unit.
