Vehicle Control System for Adverse Event Alerting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle network systems face challenges in promptly and efficiently communicating adverse events, such as collisions or obstructions, to other vehicles, which can lead to increased risk and delays, especially when onboard communication systems are inoperable or crew members are unable to initiate reporting.
Innovation Solution
A vehicle control system with an onboard controller that receives event signals from sensors or user interfaces, determines event information, and generates alerts to communicate directly with other vehicles and offboard control systems to modify their routes and avoid adverse event locations, ensuring timely notification and route adjustments without relying on manual dispatch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual reporting methods are used for adverse events, then system complexity is reduced, but communication speed and reliability deteriorate when crew members are unable to initiate reporting
Solution Approach 1:
The system enables self-service by allowing the vehicle's communication system to automatically generate and transmit adverse event alerts without requiring manual initiation by crew members. The onboard controller detects adverse events through sensors and autonomously communicates event information to other vehicles and offboard control systems, ensuring reliable reporting even when crew members are incapacitated.
Solution Approach 2:
The system replaces manual mechanical reporting methods with automated electronic communication. Instead of relying on crew members to manually notify other vehicles or control centers, the onboard controller uses communication devices to electronically transmit event alerts, significantly improving reporting reliability while maintaining manageable system complexity through integrated automation.
2Speed
If automated event detection and communication systems are implemented, then communication speed and safety improve, but device complexity increases
Solution Approach 1:
The onboard controller serves multiple functions: it manages normal vehicle operations, detects adverse events through integrated sensors, processes event information, and communicates alerts through communication devices. By consolidating these diverse functions into a single multi-functional controller, the system achieves fast automated event notification while managing complexity through functional integration rather than proliferation of separate components.
Solution Approach 2:
The system merges sensor detection, event processing, and communication functions into an integrated automated reporting system. The onboard controller combines data from various sensors to detect adverse events and automatically transmits event information through communication devices, eliminating the need for separate manual reporting systems and achieving rapid notification with coordinated system complexity.
3Object-affected harmful factors
If real-time event communication to multiple vehicles is implemented, then collision avoidance effectiveness improves, but information transmission complexity increases
Solution Approach 1:
The system uses the offboard control system as an intermediary to manage information distribution. The onboard controller transmits event information to the offboard control system, which then processes and distributes route modification commands to multiple second vehicles. This intermediary approach ensures accurate and consistent information transmission to all affected vehicles while managing communication complexity through centralized coordination.
Solution Approach 2:
The communication process is segmented into distinct functional stages: event detection by sensors, information processing by the onboard controller, relay through the offboard control system, and final route modification by affected vehicles. This segmentation allows real-time communication to multiple vehicles while managing information transmission complexity by dividing the overall communication task into manageable, specialized components.

AI summary
A system and method receive an event signal indicative of an adverse event on a vehicular pathway from one or more of a user interface device or one or more sensors disposed onboard the first vehicle. Event information is determined that is associated with the adverse event on the vehicular pathway and the first vehicle. An event alert is generated that contains the event information, and a communication device onboard the first vehicle is controller to communicate the event alert to an offboard control system configured to control movement of one or more second vehicles based on the event alert by modifying a respective planned route of each of the one or more second vehicles to bypass a location of the adverse event. The one or more second vehicles are not mechanically connected to the first vehicle and do not operate under control of the first vehicle.
