Dual-Circuit Vehicle Communication for Intersection Radio Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing a radio link between vehicles entering an intersection is difficult in inter-vehicle communication, leading to potential safety risks due to delayed information exchange.
Innovation Solution
A communication apparatus with dual communication circuits operating as an access point and a station in infrastructure mode, allowing vehicles to maintain communication with preceding vehicles while establishing links with incoming vehicles at intersections using phased array antennae and routing protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PBSS mode is used for inter-vehicle communication, then communication between vehicles can be established, but establishing a radio link between vehicles entering an intersection is difficult
Solution Approach 1:
The communication apparatus is divided into two independent communication circuits: a first communication circuit operating as an access point for communicating with vehicles in front, and a second communication circuit operating as a station for communicating with vehicles at intersections. This segmentation allows each circuit to handle specific communication scenarios independently, resolving the contradiction by enabling reliable radio link establishment at intersections without disrupting ongoing communications with preceding vehicles.
2Reliability
If a single communication mode is used, then device complexity is reduced, but communication reliability at intersections deteriorates
Solution Approach 1:
The communication apparatus implements multi-functionality by equipping it with both access point and station communication circuits, allowing the same device to operate in multiple modes (infrastructure mode and ad-hoc mode) depending on the communication scenario. This universal design enables reliable communication at intersections while maintaining the ability to communicate with preceding vehicles, balancing reliability improvement with acceptable device complexity.

AI summary
A communication apparatus mounted on a vehicle includes: a first communication circuit that operates as an access point of an infrastructure mode and transmits and receives a radio wave toward and from a front side of the vehicle; and a second communication circuit that operates as a station of an infrastructure mode and transmits and receives a radio wave toward and from the front side of the vehicle.
