Driver Attention Management via Closed-Loop Convenience Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving systems face challenges in maintaining driver attentiveness and supervisory control, as existing systems often distract drivers or rely on external triggers, failing to ensure continuous attention and effective control during vehicle operation.
Innovation Solution
A closed-loop driver attention management system that uses sensors and light cues to monitor and manage driver attention, providing alerts and diagnostics to ensure the driver maintains sufficient control, employing a convenience messaging system and staged alerting to maintain driver engagement through visual, auditory, and haptic prompts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver monitoring systems and displays are used to inform drivers of their attentiveness, then driver attentiveness is improved, but driver distraction increases and attentiveness to driving task decreases
Solution Approach 1:
The patent introduces a convenience messaging system as an intermediary that provides non-driving-related information to the driver. This system acts as a mediator between the driver and the road environment, engaging driver attention through interesting content while subtly monitoring and correcting attention levels without creating distracting displays about attentiveness itself.
Solution Approach 2:
The system employs closed-loop diagnostics where the convenience messaging system itself serves as both the stimulus and the monitoring tool. By analyzing driver responses to convenience messages, the system automatically diagnoses sensor errors and determines driver attentiveness without requiring separate monitoring displays, thus avoiding distraction while maintaining reliability.
2Reliability
If forward collision warning systems are used to attract distracted driver attention, then driver attention is improved, but the system can only activate based on external triggers rather than operating constantly
Solution Approach 1:
The convenience messaging system operates continuously rather than being triggered only by external events. It provides ongoing engagement and monitoring, maintaining a constant connection with the driver's attention state. This continuous operation allows the system to detect attention lapses proactively rather than reactively, improving both reliability and adaptability.
Solution Approach 2:
The system implements closed-loop feedback by continuously monitoring driver responses to convenience messages and using this information to diagnose attentiveness levels. This feedback mechanism allows the system to adapt its operation based on real-time driver state, enabling it to activate corrections continuously rather than waiting for external triggers.
3Reliability
If multiple sensors and alert systems are deployed to monitor driver attention, then driver attentiveness is improved, but system complexity increases
Solution Approach 1:
The convenience messaging system serves multiple functions simultaneously: it provides useful information to the driver, engages driver attention, monitors driver responsiveness, and diagnoses sensor functionality. This multi-functionality reduces the need for separate dedicated monitoring systems, thereby improving attentiveness while limiting complexity growth.
Solution Approach 2:
The patent merges the driver engagement function with the driver monitoring function into a single integrated system. The convenience messaging system combines entertainment/information delivery with attentiveness monitoring and sensor diagnostics, consolidating multiple systems into one unified approach that improves reliability without proportionally increasing complexity.

AI summary
A method and system for driver attention management system may include means for closed-loop diagnostics. A convenience message may alert a driver of an item of interest to the driver. A sensor may detect the driver's response to the convenience message. Based on the response to the convenience message, the characteristics of an attentive response from the driver may be determined. The determined attentive response may be used by a driver attention management system. The driver attention management system may be able to diagnose errors in the sensors that are used in the driver attention management system. The driver attention management system may also be able to determine whether a driver is exercising sufficient supervisory control of a vehicle by determining whether the driver is attentively responding to prompts provided by the driver attention management system. The driver attention management system may be used in an autonomous or semi-autonomous driving system.
