Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems fail to predict and proactively mitigate the impact of glare, which significantly impairs visibility and increases the risk of accidents.
Innovation Solution
A system that utilizes real-time sensor data, digital image data, and map databases to analyze glare factors, creating a glare factor map to recommend routes that minimize glare exposure, and can operate vehicles manually or autonomously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time sensor data and digital image data are collected and analyzed to determine glare factors, then the ability to predict and avoid glare is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The system divides glare detection into multiple independent sensor components (optical sensors, digital image sensors) that each capture specific aspects of glare conditions. This segmentation allows the complex task of glare prediction to be broken down into manageable data streams that can be processed independently and then integrated, improving reliability without overwhelming the system with monolithic complexity
Solution Approach 2:
The system performs preliminary analysis of sensor data and digital image data before actual glare occurs, creating predictive models of glare conditions based on environmental factors, sun position, and historical data. This preliminary action enables the system to anticipate glare events and prepare mitigation strategies in advance, enhancing prediction accuracy while allowing processing to be distributed over time
2Reliability
If route recommendations are provided to minimize glare exposure, then driver safety and visibility are improved, but the navigation system complexity and computational requirements increase
Solution Approach 1:
The navigation system dynamically adjusts route recommendations based on real-time glare predictions, vehicle position, and environmental conditions. Rather than providing static routes, the system continuously evaluates multiple potential paths and updates recommendations as conditions change, allowing the navigation complexity to adapt to actual needs while maintaining driver safety
Solution Approach 2:
The system introduces an intermediary processing layer that translates complex sensor data and glare predictions into simplified route recommendations presented to the driver. This intermediary layer filters and synthesizes information from multiple sources, managing the complexity of data integration while providing clear, actionable guidance to the driver without overwhelming the user interface
3Object-affected harmful factors
If automated vehicular control is implemented in response to detected glare, then accident risk is reduced, but the control system complexity and automation level increase
Solution Approach 1:
The automated control system implements preliminary anti-actions by detecting glare conditions and automatically adjusting vehicle controls (such as activating windshield shading, adjusting headlight direction, or modifying cruise control parameters) before the glare can significantly impact driving safety. This proactive automated response reduces accident risk by counteracting glare effects before they become hazardous, while keeping automation focused on specific glare-related controls rather than comprehensive vehicle management

AI summary
Aspects of the present disclosure describe systems, methods, and devices for automated vehicular control based on glare detected by an optical system of a vehicle. In some aspects, automated control includes controlling the operation of the vehicle itself, a vehicle subsystem, or a vehicle component based on a level of glare detected. According to some examples, controlling the operation of a vehicle includes instructing an automatically or manually operated vehicle to traverse a selected route based on levels of glare detected or expected along potentials routes to a destination. According to other examples, controlling operation of a vehicle subsystem or a vehicle component includes triggering automated responses by the subsystem or the component based on a level of glare detected or expected. In some additional aspects, glare data is shared between individual vehicles and with a remote data processing system for further analysis and action.
