Intra-Vehicle Pedestrian Communication System for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack effective communication and data-sharing mechanisms between vehicles and pedestrians in real-time, especially during events of interest or safety concerns, and do not adequately address traffic management and collision avoidance in dynamic driving environments.
Innovation Solution
A wireless network system that enables communication and data sharing between vehicles and pedestrians through V2V, V2P, and V2I links, using sensors and cameras for real-time data acquisition and transmission, and adaptive warning systems to prevent collisions, with features like automatic sensor activation and emergency response protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time communication and data sharing between vehicles and pedestrians is implemented, then safety and collision avoidance improve, but system complexity and infrastructure requirements increase
Solution Approach 1:
The system segments communication into multiple layers: V2V (vehicle-to-vehicle), V2P (vehicle-to-pedestrian), and V2I (vehicle-to-infrastructure). Each layer handles specific communication tasks independently, reducing overall system complexity while maintaining comprehensive safety coverage
Solution Approach 2:
The wireless communication system is designed to perform multiple functions simultaneously: collision detection, emergency notification, traffic management data collection, and infrastructure communication. This multi-functionality reduces the need for separate dedicated systems for each safety function
2Measurement precision
If comprehensive sensor activation and data acquisition are used for collision detection, then measurement precision improves, but energy consumption increases
Solution Approach 1:
The sensor activation system dynamically adjusts its operation based on detected conditions. Sensors are activated only when potential collision risks are detected or when vehicles are in proximity to pedestrians or infrastructure, rather than operating continuously. This dynamic activation maintains high measurement precision for collision detection while significantly reducing overall energy consumption
Solution Approach 2:
The system uses data from other sensors and communication channels to trigger sensor activation. For example, V2V communication data or V2P communication data can trigger the activation of additional sensors, allowing the system to self-regulate its data acquisition based on detected needs rather than requiring constant external control
