ADAS Warning Feedback Using Historical Driver Reactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems lack a systematic approach to determine the appropriate degree and type of feedback to provide to drivers based on their historical reactions to similar situations.
Innovation Solution
An advanced driver assistance system (ADAS) that utilizes historical driver reaction data to analyze and adapt the intensity and type of feedback, such as audio, visual, or haptic warnings, by combining inputs from forward-looking cameras, a ranging module, and a rear-looking driver state monitoring camera, and using a processor to retrieve and analyze historical feedback data to inform real-time decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver assistance systems provide warnings to drivers, then driver safety is improved, but the system cannot determine the appropriate intensity and type of warning without historical data
Solution Approach 1:
The system performs preliminary actions by collecting and storing driver reaction data during normal operation. Historical data about driver responses to various warning types is accumulated before actual hazard situations occur, enabling the system to make informed decisions about warning intensity when needed.
Solution Approach 2:
The system implements feedback by continuously monitoring driver reactions to warnings and using this information to adjust future warning strategies. The processor analyzes historical feedback data to determine optimal warning approaches for different driver types and situations.
2Ease of operation
If the system provides standardized warnings to all drivers, then system complexity is reduced, but driver alertness and effectiveness are compromised
Solution Approach 1:
The system applies local quality by tailoring warning characteristics to individual driver needs and specific situation contexts. Different drivers receive different types and intensities of warnings based on their historical reaction patterns, rather than applying a uniform approach to all users.
Solution Approach 2:
The system implements dynamics by making warning strategies adaptable and changeable based on accumulated data. The warning approach evolves over time as the system learns from driver reactions, transitioning from static standardized warnings to dynamic personalized warnings.
3Loss of information
If the system collects and analyzes historical driver reaction data, then feedback effectiveness is improved, but data processing requirements and system complexity increase
Solution Approach 1:
The system extracts only the essential and relevant features from historical driver reaction data, rather than processing complete raw datasets. The processor identifies and utilizes key patterns in driver responses to warnings, separating critical information from unnecessary data.
4Measurement precision
If the system uses multiple sensors and cameras to monitor driver state, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The system merges multiple sensing functions into an integrated driver monitoring system. The rear-looking camera combines facial expression analysis with driver state monitoring, consolidating multiple detection capabilities into a unified system that reduces overall complexity.

AI summary
The present invention provides a method and system of historical emotion based driver advanced assistance. In this method, a combination of external environment to a vehicle on which the advanced driver assistance system (ADAS) is mounted fetched by forward looking cameras is combined with rear looking camera for internal environment or driver state, is generated. The generated combination is utilized to analyze is there is any critical situation that is upcoming. For providing feedback for such situation, the ADAS fetches a historical combination situation similar to the current situation combination. The intensity of the feedback is varied as per the driver reaction to the feedback provided to the driver at such historical combination situation.
