Proxy ITS Station for Legacy Vehicle Safety Integration

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Legacy vehicles without Intelligent Transport System (ITS) capabilities pose challenges for modern ITS systems, as they cannot share information or receive hazard alerts, limiting the overall operation and safety of the transportation system.

Innovation Solution

A mobile device acts as a proxy ITS station for non-V2X enabled vehicles, detecting proximity and lack of ITS messages, then communicates vehicle information and alerts to the ITS system, using interfaces like Apple CarPlay or MirrorLink, and provides visual or audio alerts to the driver.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ITS systems are deployed with modern vehicles, then safety and communication capabilities are improved, but legacy vehicles without ITS capabilities cannot participate in the system

Engineering Contradiction:

ImprovesafetyVSAvoidlegacy vehicle integration

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

A portable computing device acts as an intermediary between legacy vehicles and the ITS system. The device detects ITS messages from other vehicles and infrastructure, then provides appropriate alerts to the driver of the legacy vehicle through visual or audio interfaces, enabling legacy vehicles to benefit from ITS safety capabilities without requiring built-in ITS hardware

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The portable computing device copies ITS station functionality to legacy vehicles. By running ITS message detection and processing software on the portable device, the system creates a virtual ITS station that replicates the safety communication capabilities normally present only in modern vehicles

Inventive Principle:

Principle #26Copying

2Reliability

If ITS messages are monitored continuously, then hazard detection capability is improved, but energy consumption increases

Engineering Contradiction:

Improvehazard detectionVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The portable computing device performs periodic sampling of ITS messages rather than continuous monitoring. The device detects ITS messages at regular intervals and processes only relevant hazard information, reducing energy consumption while maintaining effective hazard detection capabilities for legacy vehicle integration

Inventive Principle:

Principle #19Periodic action

AI summary

A method at a computing device for the computing device to act as an intelligent transportation system (ITS) station for a vehicle, the method including detecting that the computing device is proximate to the vehicle; determining whether ITS messages are being sent on behalf of the vehicle; and if the determining finds ITS messages are not being sent on behalf of the vehicle, the computing device acting as the ITS station for the vehicle.
