V2X Module Automatic Aid Request Signatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles often face challenges in requesting aid when occupants are unable to use cellular phones or when there are no observers available to do so, leading to increased response times and potential escalation of vehicle or medical emergencies.
Innovation Solution
A Vehicle-to-Everything (V2X) communication system that generates and transmits a Basic Safety Message (BSM) including a vehicle aid request signature, allowing vehicles to automatically request aid through a V2X module, which includes vehicle location information, according to SAE Surface Vehicle Standard J2735, enabling faster assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a pedestrian or observer requests aid using a mobile device, then aid can be requested, but response time increases when no observer is available or occupants cannot use mobile devices
Solution Approach 1:
The vehicle system automatically monitors its own conditions and autonomously transmits aid requests without requiring external observers or occupant intervention. The system detects triggering events (vehicle immobilization, disabled status, airbag deployment) and automatically generates BSM messages with aid request signatures, enabling the vehicle to request aid independently.
Solution Approach 2:
The patent introduces a V2X communication module as an intermediary between the vehicle and external emergency response systems. This module automatically transmits BSM messages containing aid request signatures and vehicle location information to external devices, eliminating the need for direct human intervention while maintaining reliable communication.
2Reliability
If manual aid requests are used via mobile devices, then aid can be requested, but the system complexity increases due to dependency on external devices
Solution Approach 1:
The V2X communication module performs multiple functions: it monitors vehicle conditions, detects triggering events, generates BSM messages with appropriate aid request signatures, and transmits communications to external devices. This multi-functional approach consolidates what would otherwise require separate systems, reducing overall complexity while improving reliability.
Solution Approach 2:
The system pre-configures BSM message templates with various aid request signatures corresponding to different vehicle conditions (immobilization, disabled status, airbag deployment). When a triggering event occurs, the system simply selects and transmits the appropriate pre-configured message, eliminating the need for complex real-time message construction and reducing system complexity.
3Loss of time
If automatic vehicle monitoring is implemented, then response time decreases, but device complexity increases
Solution Approach 1:
The patent integrates the aid request monitoring and transmission functionality into the existing V2X communication module, which is already part of the vehicle's standard communication infrastructure. By merging the aid request detection and message transmission functions into an existing module rather than adding separate systems, the patent reduces overall device complexity while achieving automatic monitoring and rapid response.
