Vehicle Hazard Notification via Automatic Parking Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle operators may be distracted from activating hazard lighting or hazard notification systems, especially in roadside situations, leading to potential safety hazards due to unaddressed vehicle location and status conditions.
Innovation Solution
A hazard notification system comprising exterior lights, a positioning system, and sensors that automatically activate lighting patterns based on vehicle location, status, and approaching objects to provide visual warnings, including distinguishing between established and unestablished parking regions, and identifying vehicle passengers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle operators manually activate hazard lighting, then hazard notification is provided, but operator distraction prevents timely activation
Solution Approach 1:
The system automatically detects parking conditions and activates hazard lights without operator intervention. The controller monitors positioning system data to identify unestablished parking regions and autonomously triggers the hazard notification system, eliminating the need for manual activation and ensuring reliable operation even when operators are distracted.
Solution Approach 2:
The system performs preliminary detection of parking location and status before hazard notification is needed. By continuously monitoring positioning data and vehicle status, the system is ready to activate hazard lights immediately when parked in unestablished regions, preventing the delay caused by manual activation.
2Reliability
If hazard lighting is automatically activated, then operator distraction is addressed, but system complexity increases
Solution Approach 1:
The system leverages existing multi-functional vehicle components: the positioning system serves both navigation and hazard detection purposes, the controller manages multiple vehicle functions including lighting and status monitoring, and the hazard lights provide both standard signaling and automatic hazard notification. This reduces overall system complexity by reusing existing infrastructure.
Solution Approach 2:
The patent combines hazard detection, location analysis, and lighting control into a single integrated controller. The positioning system data is processed together with vehicle status information to trigger unified hazard notification, consolidating multiple functions into one control unit rather than requiring separate systems for each function.
3Adaptability or versatility
If distinction between established and unestablished parking regions is implemented, then targeted hazard notification is provided, but measurement precision requirements increase
Solution Approach 1:
The system applies different hazard notification behaviors based on location characteristics. In unestablished parking regions, automatic hazard activation occurs with specific lighting patterns, while established regions use different or no automatic activation. This localized approach to hazard notification based on region type provides adaptability without requiring extremely precise location classification throughout all areas.
Data Source
AI summary
A hazard notification system for a vehicle is disclosed. The system comprises a plurality of exterior lights and a positioning system configured to identify a location of the vehicle. The system further comprises a controller. The controller is configured to identify the vehicle in an unestablished parking region based on the location and receive an indication of a parked condition of the vehicle. In response to the parked condition and the vehicle located in the unestablished parking region, the controller is configured to activate the exterior lights.
