Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in forming appropriate platoons while reducing communication load between vehicles, as intervehicle communication leads to increased processing time and potential delays in information exchange, especially with the adoption of non-contact power feeding infrastructure.
Innovation Solution
A vehicle control system that includes a transmission unit for non-contact communication with infrastructure, a control unit for acquiring and processing platoon information, and a driving support apparatus that creates and transmits platoon information, allowing vehicles to travel efficiently without relying on direct intervehicle communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If intervehicle communication is used to form vehicle platoons, then platoon formation capability is improved, but communication load and processing time increase
Solution Approach 1:
The infrastructure (roadside units, communication towers) serves as an intermediary to relay platoon formation information between vehicles. Instead of direct intervehicle communication, vehicles communicate through the infrastructure, which reduces communication load on individual vehicles and enables scalable platoon formation without increasing processing time linearly with the number of vehicles.
2Speed
If direct intervehicle communication is implemented, then real-time information exchange is improved, but communication load between vehicles increases
Solution Approach 1:
The communication system is segmented into infrastructure-based communication and minimal intervehicle communication. The infrastructure handles the bulk of information exchange (platoon formation, routing, coordination), while vehicles only need to communicate essential status information. This segmentation reduces the communication load between vehicles while maintaining real-time information exchange capability.
3Use of energy by moving object
If non-contact power feeding infrastructure is added, then energy supply capability is improved, but system complexity increases
Solution Approach 1:
The non-contact power feeding infrastructure is designed to serve multiple functions: it provides wireless energy transfer to vehicles and simultaneously serves as a communication node for platoon formation and coordination. By making the infrastructure multi-functional, the patent avoids adding separate complex systems for power and communication, thereby reducing overall system complexity while maintaining energy supply capability.
