Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers often fail to notice hazardous events in dynamic driving environments due to distractions or information overload, leading to potential accidents, as existing systems lack effective advanced warning mechanisms.
Innovation Solution
A neural network-based system that predicts hazardous events from road-scene data, utilizing cameras and sensors to generate risk-weighted saliency maps, providing real-time alerts and warnings to drivers or enabling autonomous control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If drivers monitor all dynamics in the driving environment, then hazard detection capability is improved, but driver attention and processing capacity are overwhelmed
Solution Approach 1:
The patent introduces an intermediary system comprising cameras, sensors, and neural networks that act as a mediator between the complex driving environment and the driver. This intermediary processes visual and sensor data to identify and highlight hazardous events, reducing the cognitive burden on drivers while maintaining high hazard detection capability through automated pattern recognition and anomaly detection
Solution Approach 2:
The patent replaces the mechanical human cognitive processing system with an electronic neural network-based system for hazard detection. The neural networks analyze sensor data and generate hazard predictions, substituting human attention and processing capacity with automated computational systems that can handle complex pattern recognition without fatigue or distraction
2Reliability
If drivers maintain constant attention to the road, then hazard detection is improved, but driver fatigue and distraction increase
Solution Approach 1:
The patent implements preliminary action by using neural networks to predict hazardous events before they fully manifest. The system analyzes current sensor data and predicts future hazard occurrences, allowing drivers to be alerted in advance rather than requiring constant reactive attention. This predictive capability extends the effective duration of driver attention by providing advance warning of potential threats
Solution Approach 2:
The patent employs feedback mechanisms where the system continuously monitors driver state and environmental conditions, then provides targeted alerts only when hazards are detected. This selective feedback approach maintains high hazard detection reliability while reducing unnecessary driver engagement, allowing drivers to maintain lower baseline attention levels without compromising safety
3Loss of information
If advanced warning systems provide frequent alerts, then driver awareness is improved, but false alarms and driver annoyance increase
Solution Approach 1:
The patent applies local quality by providing differentiated alert levels and types based on the specific hazard detected. Rather than uniform frequent alerts, the system tailors warning intensity and frequency to the severity and nature of each detected hazard, delivering critical information only when necessary while reducing false alarm impact through context-aware alert management

AI summary
A system for predicting a hazardous event from road-scene data includes an electronic control unit configured to implement a neural network and a camera communicatively coupled to the electronic control unit, wherein the camera generates the road-scene data. The electronic control unit is configured to receive the road-scene data from the camera, and predict, with the neural network, an occurrence of the hazardous event within the road-scene data from the camera.
