Autonomous Vehicle Guidance Using 3D Traffic Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicles operate independently, leading to suboptimal driving efficiency in mixed fleets, including increased fuel consumption, safety risks, and traffic inefficiencies, as they lack a system to coordinate with other vehicles and objects in real-time.
Innovation Solution
A system that utilizes 3D-measuring means to detect and identify autonomous vehicles and objects, aggregates their positions and movements with a road map, and generates instructions for optimized driving efficiency based on total traffic parameters, including fuel consumption, safety, and traffic flow, using processing means to transmit these instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If autonomous vehicles operate individually to optimize their own efficiency, then individual vehicle fuel consumption decreases, but total traffic flow efficiency deteriorates
Solution Approach 1:
The patent merges individual vehicle optimization with collective traffic optimization by implementing a communication system where autonomous vehicles share position, speed, and trajectory data. The central server aggregates this information to generate coordinated instructions for multiple vehicles, transforming isolated individual optimization into a unified system that optimizes both individual fuel consumption and overall traffic flow efficiency simultaneously.
Solution Approach 2:
The system implements continuous feedback loops where vehicles report their status to the central server, which then generates optimized instructions based on aggregated data from all vehicles. This feedback mechanism allows the system to dynamically adjust individual vehicle instructions to maintain both individual efficiency and collective traffic flow optimization, resolving the contradiction between individual and total efficiency.
2Speed
If autonomous vehicles make individual traffic decisions, then reaction time improves compared to human drivers, but traffic flow optimization deteriorates
Solution Approach 1:
The patent introduces a central server as an intermediary that receives data from all autonomous vehicles and generates coordinated instructions. This intermediary processes aggregated information from multiple vehicles and provides optimized guidance that individual vehicles cannot achieve alone, thereby improving overall traffic flow optimization while preserving the fast reaction time capability of autonomous vehicles.
3Productivity
If a system coordinates multiple autonomous vehicles to optimize total driving efficiency, then overall traffic flow improves, but system complexity increases
Solution Approach 1:
The patent segments the complex coordination task into manageable components: individual vehicles independently detect and report their own position, speed, and trajectory; the central server aggregates this data and generates coordinated instructions; and vehicles execute the received instructions. This segmentation distributes computational complexity across multiple independent units rather than requiring one complex centralized control system, thereby improving overall traffic flow while managing system complexity.
