ADAS Deactivation Tracking for Driver Risk Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliance on Advanced Driver Assistance Systems (ADAS) by drivers can lead to difficulties in accurately determining potential or actual safety risks, as driver dependence on these systems may result in unsafe environments due to false positives and ignored warnings, affecting driving behavior evaluation and safety features' effectiveness.
Innovation Solution
A computer-implemented method and system that detect and act upon deactivated ADAS components by receiving measurements data, comparing it to historical driving data, and determining a likelihood level of alert provision, which is used to set an operator profile, helping assess driving behavior and safety risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If driver reliance on ADAS systems increases, then automation level improves, but safety risk increases due to false positives and ignored warnings
Solution Approach 1:
The system implements feedback by monitoring driver responses to ADAS alerts and using this information to adjust future alert behavior. The driver behavior evaluation system continuously collects data on how drivers respond to alerts (acknowledgment, correction action, no action) and uses this feedback to refine the likelihood assessment model, creating a closed-loop system that adapts to individual driver patterns while maintaining safety standards
Solution Approach 2:
The patent replaces traditional mechanical driver monitoring methods with electronic sensor-based detection systems. Instead of relying on physical observation or manual assessment of driver behavior, the system uses sensors, cameras, and data processing algorithms to automatically detect and evaluate driver responses to ADAS alerts, enabling more precise and consistent behavioral assessment
2Device complexity
If ADAS features are deactivated, then device complexity reduces, but measurement precision of driving behavior deteriorates
Solution Approach 1:
The system introduces an intermediary evaluation layer that processes ADAS data even when features are deactivated. Rather than directly relying on active ADAS components for behavior assessment, the system uses an intermediate likelihood assessment model that infers driving behavior from available data points and historical patterns, maintaining measurement precision without requiring full ADAS activation
Solution Approach 2:
The patent dynamically changes system parameters based on ADAS activation status. When ADAS features are deactivated, the system adjusts its measurement parameters to rely more heavily on historical driving data and statistical likelihood models rather than real-time sensor data, thereby maintaining evaluation accuracy across different system configuration states
3Ease of operation
If driver dependence on ADAS increases, then ease of operation improves, but harmful factors increase due to unsafe driving environments
Solution Approach 1:
The system applies preliminary anti-action by proactively identifying and addressing potential safety risks before they manifest as actual hazards. The driver behavior evaluation system continuously assesses driver responses to ADAS alerts and predicts likelihood of unsafe behavior, allowing the system to intervene with targeted alerts or notifications before dangerous driving patterns develop
Solution Approach 2:
The system implements feedback by monitoring driver responses to ADAS alerts and using this information to adjust future alert behavior. The driver behavior evaluation system continuously collects data on how drivers respond to alerts (acknowledgment, correction action, no action) and uses this feedback to refine the likelihood assessment model, creating a closed-loop system that adapts to individual driver patterns while maintaining safety standards
Data Source
AI summary
A system and computer-implemented method detect and act upon deactivated vehicle components. The system and method include receiving measurements data associated with driving activity. The measurements data includes an indication that at least one feature of an Advanced Driver Assistance System (ADAS) of a vehicle has been deactivated for a driving activity. The system and method may include receiving historical driving data including a history of at least one driving activity aided by activation of the alert from the ADAS feature. The system and method may compare the measurements data to the historical driving data, determine a likelihood level that the feature of the ADAS would have provided the alert had the feature been activated based upon the comparing, and set, based at least upon the determining, at least a portion of an operator profile associated with an operator of the vehicle with the likelihood level.
