Parked Vehicle Sensor Data Sharing for Blind Spot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of deploying and maintaining infrastructure-based Intelligent Transport Systems (ITS) for traffic safety, particularly in areas like city streets and parking lots, limits their availability and effectiveness, leaving vulnerable road users at risk due to the inability to detect pedestrians or objects obstructed by parked vehicles.
Innovation Solution
A method where parked vehicles can dynamically determine when to use their sensors and communicate with moving vehicles to provide sensor data for blind spots, optimizing power usage and reducing costs by leveraging vehicle-to-vehicle communications, with requests for sensor information being sent via unicast or broadcast messages, and responses processed to enhance safety and traffic efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If infrastructure-based ITS systems are deployed to detect pedestrians and improve traffic safety, then road safety and traffic efficiency are improved, but deployment and maintenance costs increase significantly
Solution Approach 1:
The patent enables parked vehicles to autonomously provide sensor data to moving vehicles through vehicle-to-vehicle communication. The parked vehicles self-activate their sensors and transmit data without requiring infrastructure deployment, thereby improving road safety while avoiding high infrastructure costs
Solution Approach 2:
The patent makes parked vehicles serve dual functions: their primary parking function and a secondary safety monitoring function. By utilizing the existing sensors in parked vehicles for detecting pedestrians and obstacles, the system achieves infrastructure-like safety coverage without additional infrastructure deployment
2Reliability
If sensors in parked vehicles are continuously activated to provide safety data, then detection reliability is improved, but battery consumption increases
Solution Approach 1:
The patent implements periodic activation of sensors in parked vehicles based on detected conditions. Sensors are activated only when a moving vehicle requests data or when potential hazards are detected, rather than continuous operation, thereby maintaining detection reliability while significantly reducing battery consumption
Solution Approach 2:
The system uses feedback mechanisms where moving vehicles broadcast requests for sensor data and parked vehicles respond based on current conditions. This feedback-driven activation ensures sensors are only powered when needed, optimizing the balance between detection reliability and energy consumption
