Vehicle Risk Area Control Using Shared Wireless Hazard Coordinates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for warning pedestrians of risk areas, such as those obscured from view, rely on vehicles having image recognition capabilities, which not all vehicles possess, leading to incomplete or delayed warnings, especially when vehicles travel in close proximity and the risk area is not within their line of sight.
Innovation Solution
A warning system that utilizes wireless communication between vehicles and a server to share position information of risk areas, allowing vehicles without image recognition capabilities to transmit and receive risk area data, ensuring timely warnings are given to both vehicles and pedestrians, even when the risk area is not visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles are equipped with image recognition capabilities to detect risk areas, then the ability to identify and warn about dangerous zones is improved, but the device complexity and cost increase for vehicles that do not require such capabilities
Solution Approach 1:
The patent introduces a server as an intermediary that centralizes the image recognition and risk area detection functions. Vehicles without advanced sensors can rely on the server to process data from other vehicles and distribute risk area information, eliminating the need for each vehicle to have its own complex image recognition system while maintaining detection accuracy.
Solution Approach 2:
The server provides a universal risk area detection service that benefits all vehicles in the network, regardless of their individual sensor capabilities. This multi-functional approach allows the same infrastructure to serve both vehicles with advanced sensors and those without, standardizing the safety functionality across the entire vehicle fleet.
2Speed
If each vehicle independently detects and warns about risk areas, then the response time is improved, but the coverage is limited to areas visible to that specific vehicle
Solution Approach 1:
The patent merges the detection capabilities of multiple vehicles through the server, which aggregates data from various sources including vehicles with different positions and viewing angles. This combination allows the system to construct a comprehensive risk area coverage that exceeds what any single vehicle could detect independently, while maintaining rapid response through centralized processing.
Solution Approach 2:
The system transitions from single-vehicle two-dimensional detection to multi-vehicle three-dimensional spatial awareness by incorporating positional information from multiple vehicles. The server processes spatial coordinates and viewing angles to create a holistic understanding of risk areas across the entire operational space, enabling coverage of zones that would be invisible to any individual vehicle.
3Loss of information
If vehicles transmit risk area information continuously, then the information availability is improved, but the communication energy consumption and data traffic increase
Solution Approach 1:
The system implements periodic information transmission where vehicles and the server exchange risk area data at predetermined intervals rather than continuously. This periodic communication maintains adequate information availability for safety purposes while significantly reducing energy consumption and network traffic compared to continuous transmission, allowing systems to function effectively on standard battery power.
Solution Approach 2:
The server performs preliminary processing and filtering of risk area information before transmission, preparing data in advance and only communicating when necessary. This preliminary action reduces the frequency and volume of transmissions by pre-identifying and prioritizing critical information, thereby lowering communication energy requirements while ensuring that essential safety data is always available.
