Backend Hazard Detection System for Unified Road Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers in road traffic are inadequately informed about potential hazards such as wild animals or black ice, with information often received through multiple channels, leading to a need for improved hazard detection and communication.
Innovation Solution
A backend system for a hazard detection system that evaluates vehicle and driver data to detect hazards and sends warnings to affected vehicles, using a centralized and automatic approach to provide reliable and unified hazard information, with features including probability-based hazard detection, consideration of boundary conditions, and data transmission via standardized protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If drivers receive hazard information through multiple channels, then information coverage is improved, but information reliability and clarity deteriorate
Solution Approach 1:
The patent merges hazard detection capabilities across multiple vehicles and combines this with backend evaluation systems to create a unified hazard information source. Instead of relying on multiple separate communication channels, the system consolidates hazard detection data from vehicle sensors and driver reports into a single evaluated hazard list that is then distributed to all vehicles, ensuring both comprehensive coverage and reliable, clear information delivery.
2Loss of information
If drivers manually report hazards, then hazard detection coverage is improved, but driver burden and response time worsen
Solution Approach 1:
The system enables vehicles to automatically detect and report hazards using onboard sensors without requiring driver intervention. Vehicle sensors continuously monitor road conditions and automatically transmit hazard data to the backend system, which then evaluates and distributes this information to other vehicles. This self-service approach eliminates the manual reporting burden on drivers while maintaining comprehensive hazard detection coverage.
Solution Approach 2:
The system performs preliminary hazard detection using vehicle sensors before drivers need to take action. By continuously monitoring road conditions through sensor data and evaluating potential hazards in advance, the system can proactively warn drivers about upcoming dangers, allowing them to prepare appropriate responses rather than reacting to manually reported hazards after they've already been encountered.
3Measurement precision
If hazard detection uses comprehensive vehicle and driver data, then detection accuracy is improved, but data processing complexity worsens
Solution Approach 1:
The patent introduces a backend evaluation system as an intermediary between vehicle data collection and hazard detection. This backend receives comprehensive vehicle and driver data from multiple sources, performs centralized evaluation and probability assessment, and then distributes the evaluated hazard information to vehicles. This intermediary approach maintains high detection accuracy by processing comprehensive data while reducing individual vehicle complexity by moving the heavy processing burden to the centralized backend system.
Data Source
AI summary
A backend for a hazard detection system comprising: a processor; and a memory in communication with the processor, the memory storing a set of instructions. The set of instructions, when accessed and executed by the processor, cause the processor to: receive vehicle and/or driver data from a vehicle, evaluate the received vehicle and/or driver data, use the evaluation as a basis for detecting a hazard in road traffic, and send the information about the detected hazard to at least one vehicle to warn said vehicle about the hazard.
