Vehicle Detection via Short-Range Wireless Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle collision prevention systems, despite advancements, still fail to adequately reduce the number of collisions, as they lack effective methods for detecting and locating nearby vehicles in real-time, especially in complex environments.
Innovation Solution
A computer-implemented method using short-range wireless communications for vehicle detection and location, where each vehicle emits a unique identifier and location signal, allowing for relative positioning of nearby vehicles without establishing a direct connection, utilizing GPS and wireless controllers to provide collision warnings and potential avoidance actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radar equipped vehicles are used to reduce collisions, then collision prevention capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical radar systems with wireless communication-based detection. Vehicles use wireless transmitters and receivers to detect and communicate with nearby vehicles, eliminating the need for complex radar hardware while achieving collision prevention through software-based location tracking and warning systems.
2Productivity
If wireless communication is used for vehicle detection without establishing connections, then detection efficiency is improved, but information accuracy may deteriorate
Solution Approach 1:
The patent uses wireless transmission of location data packets that contain copied information about vehicle position and identity. Each vehicle periodically transmits its location coordinates, and receiving vehicles process these data copies to determine relative positions, achieving efficient detection without direct connections while maintaining sufficient accuracy for collision avoidance.
