Unmanned Vehicle Route Width Control for Cost-Accurate Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing a traveling path for unmanned vehicles at work sites, such as mines, that is not unnecessarily wide is challenging, as it increases costs and affects the vehicles' ability to navigate effectively.
Innovation Solution
An unmanned vehicle management system that defines traveling areas based on vehicle width and track width, using a determination unit to assess whether the vehicle can enter the area, thereby optimizing path development and ensuring smooth navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wide traveling path is developed to ensure unmanned vehicles can navigate, then the vehicles can travel without deviation, but the cost required for developing the traveling path increases
Solution Approach 1:
The system dynamically adjusts the traveling area width parameter based on the specific vehicle width of each unmanned vehicle. Instead of using a fixed wide path for all vehicles, the management device calculates and sets an appropriate track width for each vehicle type, optimizing the balance between navigation reliability and development cost.
2Quantity of substance
If a narrow traveling path is developed to reduce costs, then the development cost is reduced, but it becomes difficult for unmanned vehicles to travel without deviation
Solution Approach 1:
The system applies different traveling area width specifications to different vehicle types based on their individual characteristics. Each unmanned vehicle receives a customized track width setting that matches its specific width, ensuring optimal navigation for each vehicle rather than using a uniform standard.
3Reliability
If a fixed wide traveling area is defined for all vehicles, then all vehicles can travel without deviation, but the system cannot adapt to different vehicle types with different widths
Solution Approach 1:
The management device implements dynamic adjustment of traveling area parameters based on the specific unmanned vehicle's width. When a vehicle enters the work site, the system determines its width and calculates an appropriate track width, then dynamically sets the traveling area boundaries to match that specific vehicle's requirements.
Solution Approach 2:
The system changes the traveling area width parameter according to the specific vehicle width of each unmanned vehicle. This parameter adaptation allows the same infrastructure to support multiple vehicle types with different dimensions while maintaining navigation accuracy for each.

AI summary
An unmanned vehicle management system includes: a traveling area definition unit that defines a traveling area on a traveling path of a work site; and a determination unit that determines whether or not an unmanned vehicle can enter the traveling area on the basis of a vehicle width indicating the width of the unmanned vehicle and a track width indicating the width of the traveling area.
