Wearable Alert Management for Vehicle ADAS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the vehicular context, existing technologies face challenges in safely conveying critical information to drivers and passengers while ensuring driver awareness and safety, particularly with the increasing use of mobile and wearable devices that may lead to distractions and reduced attention on the road.
Innovation Solution
A system and method for managing alerts in wearable devices within vehicles, which includes a data store and processor to receive and determine ADAS alerts, and selectively transmit them to paired wearable devices, providing haptic, visual, or audio notifications, and in critical situations, initiating communication with emergency responders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ADAS alerts are transmitted to wearable devices, then driver and passenger safety information is conveyed, but driver distraction and reduced attention on the road may occur
Solution Approach 1:
The patent applies local quality by differentiating notification types based on alert severity. Critical safety alerts receive prominent notifications (visual, auditory, or haptic), while non-critical alerts receive subtle notifications or are suppressed. This selective notification approach ensures that safety information is conveyed effectively without causing unnecessary driver distraction from minor alerts.
Solution Approach 2:
The system dynamically adjusts notification behavior based on driving context and alert priority. The wearable device monitors alert severity levels and modifies notification intensity accordingly, transitioning between silent mode for non-critical alerts and active notification modes for critical safety information, thereby balancing safety conveyance with distraction prevention.
2Reliability
If multiple notification methods (haptic, visual, audio) are provided, then alert delivery reliability is improved, but device complexity increases
Solution Approach 1:
The wearable device implements multi-functionality by integrating multiple notification methods (haptic feedback through vibration motors, visual notifications through LED indicators, and audio alerts through speakers) into a single unified alert delivery system. This allows the device to provide reliable alert delivery across different scenarios while maintaining a compact, integrated design rather than separate components for each notification type.
3Loss of information
If all ADAS messages are transmitted to the wearable device, then information completeness is improved, but information overload and distraction increase
Solution Approach 1:
The system extracts and filters only the most relevant ADAS alert information for transmission to the wearable device. By analyzing alert severity, type, and context, the system selectively transmits critical safety information while filtering out redundant or non-essential data, thereby maintaining information completeness for safety-critical matters while preventing information overload that could distract the driver.

AI summary
A method, system, and a variety of electronic circuits are provided herein that manage advanced driver assistance systems (ADAS) for passengers in a vehicle wearing a wearable device. The aspects disclosed herein allow the passenger/occupant/driver to receive ADAS messages/alerts, and receive haptic, video, audio notifications providing the same. As such, the passenger/occupant/driver is notified by the ADAS message in a passive manner.
