Coordinated Vehicle Alert System for Driver Distraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver alert systems generate multiple alerts simultaneously, potentially distracting the driver and reducing their ability to avoid collisions, as they operate independently without coordination between different collision avoidance systems.
Innovation Solution
A method and system that receive conditions data from multiple collision avoidance systems, determine an alert mode, and selectively coordinate alert patterns across haptic, visual, and auditory devices to provide unified and non-distracting alerts to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple collision avoidance systems generate alerts simultaneously, then the driver is warned of potential collision threats from multiple sources, but the multiple alerts may distract the driver and reduce collision avoidance effectiveness
Solution Approach 1:
The patent combines multiple independent collision avoidance alert systems into a single coordinated alert system. The control module receives conditions data from multiple collision avoidance systems and coordinates their alerts through a unified alert pattern selection process, merging separate alert functions into one integrated system that reduces driver distraction while maintaining comprehensive collision warning coverage.
Solution Approach 2:
The alert system dynamically selects and coordinates alert patterns based on real-time conditions data from multiple collision avoidance systems. The control module adjusts the alert behavior dynamically by selecting appropriate alert modes and coordinating alert patterns across different alert devices, allowing the system to adapt to varying traffic conditions and collision threats.
2Adaptability or versatility
If separate collision avoidance systems operate independently, then each system can function autonomously, but alerts from different systems are not coordinated and may confuse the driver
Solution Approach 1:
The control module serves as a universal coordinating unit that handles multiple functions: receiving conditions data from various collision avoidance systems, determining alert modes, selecting alert patterns, and coordinating alerts across multiple alert devices. This multi-functional approach maintains system independence while providing unified alert coordination.
Solution Approach 2:
The control module acts as an intermediary between multiple independent collision avoidance systems and the various alert devices. It receives conditions data from independent systems, processes this information, and coordinates the output to multiple alert devices, serving as a mediating layer that enables coordination without compromising system independence.
3Loss of information
If multiple alert devices are activated simultaneously, then the driver receives comprehensive warning information, but the uncoordinated alerts may create confusion and reduce driver response effectiveness
Solution Approach 1:
The system applies different alert patterns to different alert devices based on the specific collision threat conditions. The control module determines alert modes and selects coordinated alert patterns that are appropriate for each device and situation, ensuring that each alert device provides relevant information without creating overall confusion. This localized customization of alert quality maintains information completeness while reducing driver confusion.
Data Source
AI summary
A method of alerting a driver of a vehicle is provided. The method includes: receiving conditions data from one or more collision avoidance systems; determining an alert mode based on the conditions data; and selectively coordinating an alert pattern for more than one of haptic alert devices, visual alert devices, and auditory alert devices based on the alert mode.
