Onboard Controller Event Alert Communication for Incapacitated Crew
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle network systems face challenges in effectively communicating event information, such as collisions or emergencies, due to inoperable communication modalities or incapacitated crew, which can lead to increased accident risk and delayed emergency responses.
Innovation Solution
A method and system that utilize onboard controllers and nodes to generate and communicate event signals, including sensed parameter data and image data, to other vehicles and offboard control systems within a designated range, ensuring prompt notification and appropriate emergency responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If crew manually initiate event reporting, then communication accuracy is improved, but response time increases when crew are incapacitated
Solution Approach 1:
The system enables automatic event detection and reporting through onboard sensors and controllers that self-monitor vehicle status and autonomously transmit event information without requiring crew intervention. This resolves the contradiction by making the system self-sufficient in reporting events even when crew are incapacitated.
Solution Approach 2:
The onboard controller acts as an intermediary between sensors and communication systems, automatically processing sensor data and initiating event alerts without crew involvement. This mediator enables continuous monitoring and reporting functionality independent of crew capability.
2Reliability
If multiple communication modalities are provided, then communication reliability is improved, but system complexity increases when some modalities become inoperable
Solution Approach 1:
The onboard controller serves multiple functions including sensor data processing, event detection, and communication initiation through a single integrated system. This multi-functionality maintains communication reliability while avoiding the complexity of separate dedicated systems for each function.
Solution Approach 2:
The system combines sensor monitoring, event detection, and communication capabilities into an integrated onboard controller that automatically manages event reporting. This merging reduces overall system complexity while maintaining reliable event communication through unified control.
3Loss of time
If automatic sensor-based event detection is implemented, then response time is improved, but false event detection may increase
Solution Approach 1:
The system incorporates feedback mechanisms where the onboard controller continuously monitors sensor data and adjusts detection thresholds based on actual operating conditions. This feedback loop enables rapid automatic detection while filtering out false positives through adaptive validation.
Solution Approach 2:
The system performs preliminary validation of sensor readings against predefined criteria and historical patterns before triggering event alerts. This preliminary action enables fast automatic response while preventing false detections through pre-established validation rules.
Data Source
AI summary
Methods and systems for managing events in a vehicle network are provided. The method includes receiving an event signal indicative of an event from one or more first nodes operably coupled to a first onboard controller of a first vehicle. The event signal is generated in response to a user-based instruction or based on output from one or more sensors. The method determines event information associated with the event and the first vehicle. The event information includes sensed parameter data or image data. The method communicates an event alert containing the event information to one or more second vehicles operating in a designated range of the first vehicle and one or more offboard control systems that control movement of at least the first vehicle and the one or more second vehicles.
