Autonomous Vehicle Warning Deployment for Emergency Risk Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety systems for autonomous vehicles do not effectively warn other vehicles and pedestrians of emergency situations, necessitating manual intervention by the driver, which can be unsafe and inefficient.
Innovation Solution
A safety system for autonomous vehicles that automatically detects emergency situations and deploys warning devices in the surroundings to alert others, utilizing a warning system integrated with the vehicle's electronic computing device to implement a minimal risk maneuver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous vehicles operate without automated emergency detection and warning systems, then device complexity is reduced, but safety and reliability deteriorate due to inability to automatically respond to mechanical failures or loss of perception
Solution Approach 1:
The warning system continuously monitors the operating modes of vehicle subsystems in advance and automatically detects emergency situations before they escalate. The system is pre-configured with minimal risk procedures that are automatically executed upon detecting emergencies, such as deploying warning devices without human intervention, thereby improving safety through proactive automated response
Solution Approach 2:
The autonomous vehicle's safety system performs self-monitoring and self-response functions. The warning system automatically detects emergencies in subsystems and autonomously deploys warning devices according to predetermined minimal risk procedures, enabling the vehicle to service its own safety needs without external human intervention, thus improving reliability while managing complexity through automation
2Productivity
If manual intervention is required for emergency response, then system complexity is reduced, but response time and productivity deteriorate due to human reaction delays
Solution Approach 1:
The warning system continuously monitors the operating modes of vehicle subsystems and provides real-time feedback on system status. When emergencies are detected through this feedback mechanism, the system automatically executes minimal risk procedures including deploying warning devices, eliminating human reaction delays and improving response time through continuous monitoring and automated feedback-driven action
Solution Approach 2:
The system replaces manual human intervention with automated electronic control for emergency detection and response. The warning system uses electronic monitoring of subsystem operating modes and automated deployment mechanisms for warning devices, substituting mechanical human actions with electronic automation to achieve faster response times while managing complexity through integrated control systems
