Vehicle Control System Dynamic Negotiation Area Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems for self-driving vehicles do not allow for dynamic adjustment of information content based on responses from other vehicles, limiting smooth negotiation and optimization of travel plans.
Innovation Solution
A vehicle control system that includes a planned route creator, a non-traveling area planner, a transmission unit, a negotiation area information receiver, and a permissible area determiner, allowing for the calculation and inclusion of negotiation areas in non-traveling areas based on received information from other vehicles, enabling dynamic adjustment of travel plans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the self-driving vehicle transmits a fixed non-traveling area plan to other vehicles, then the transmission process is simple and quick, but the system cannot adapt to negotiation requests from other vehicles and optimize travel plans dynamically
Solution Approach 1:
The system dynamically adjusts the non-traveling area plan based on negotiation requests from other vehicles. The control unit receives negotiation requests, determines negotiation areas within the non-traveling area, and transmits updated plans that reflect these negotiations, enabling the system to adapt flexibly to changing conditions while maintaining a relatively simple overall structure.
Solution Approach 2:
The system implements a feedback mechanism where other vehicles can send negotiation requests to the self-driving vehicle. The control unit processes these requests, determines appropriate negotiation areas, and sends updated non-traveling area plans back to the requesting vehicles, creating a closed-loop communication system that enables adaptive optimization.
2Productivity
If the self-driving vehicle includes multiple negotiation areas in the non-traveling area, then the optimization of travel plans is improved, but the information processing and communication load increases
Solution Approach 1:
The non-traveling area is divided into multiple discrete negotiation areas, each of which can be independently evaluated and negotiated. This segmentation allows the system to process and optimize specific areas individually rather than treating the entire non-traveling area as a single unit, improving optimization efficiency while managing processing complexity.
Solution Approach 2:
The system negotiates only the specific areas within the non-traveling area that are relevant to other vehicles' routes, rather than renegotiating the entire non-traveling area plan. This partial action approach reduces information processing time and communication overhead while still achieving effective optimization where needed.

AI summary
The non-traveling area plan creating unit 4 creates a plan of the non-traveling area, which is an area where the self-driving vehicle 10 can travel and which is an area set as an area where the self-driving vehicle 10 does not travel. The negotiation area information receiving unit 9 receives, from another vehicle, information on one or more negotiation areas each of which is an area other than the non-traveling area and is a subject of negotiation to be included in the non-traveling area. The permissible area determining unit 35 calculates, for each negotiation area, the first value which is the value of the negotiation area indicated by the information for the self-driving vehicle 10, and determines one negotiation area permissible to be included in the non-traveling area, or determines not to include any negotiation area in the non-traveling area.
