Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where unmanned vehicles and manned vehicles operate together, effective path planning is hindered due to differences in driving strategies and the inability of unmanned vehicles to predict manned vehicle intentions, leading to traffic congestion and operational disorders.
Innovation Solution
A system and method for planning driving paths that involve assigning transportation tasks to both unmanned and manned vehicles using positioning data from an area sensing system and map data, allowing for unified path planning by transmitting planned paths to mobile devices, enabling both types of vehicles to operate effectively within predetermined areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unmanned vehicles and manned vehicles operate independently with different driving strategies, then each vehicle can maintain its own driving characteristics, but path planning becomes ineffective and traffic congestion occurs
Solution Approach 1:
The patent introduces a centralized planning device as an intermediary that receives positioning data from both unmanned and manned vehicles, processes their respective driving characteristics, and generates coordinated driving paths. This mediator enables unified path planning while preserving the individual driving strategies of each vehicle type, resolving the contradiction between adaptability and planning effectiveness.
2Reliability
If unmanned vehicles adopt conservative driving strategies, then safety is improved, but inability to predict manned vehicle intentions leads to operational disorders
Solution Approach 1:
The patent implements a feedback mechanism where the planning device continuously receives positioning data from both vehicle types and uses this information to predict manned vehicle intentions. The system processes the conservative driving patterns of unmanned vehicles alongside the aggressive patterns of manned vehicles, generating coordinated paths that account for predicted intentions, thus maintaining safety while reducing information loss.
3Productivity
If unified path planning is implemented for both vehicle types, then traffic congestion is reduced, but coordination complexity increases
Solution Approach 1:
The patent segments the path planning process into distinct modules: a data reception module that collects positioning information from both vehicle types, a processing module that applies different algorithms for unmanned and manned vehicles based on their driving characteristics, and a path generation module that outputs coordinated driving paths. This segmentation manages coordination complexity while achieving improved traffic flow efficiency.
