Steering Wheel Turn Detection for Driver Fatigue Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing rate of car accidents due to driver fatigue and slow response times, which existing technologies have not adequately addressed through electronic driver fatigue detection systems.
Innovation Solution
A driving alert system that includes a turn detector on the steering wheel to detect hazardous turns and generate alert signals, and ultrasonic transceivers to detect head-swing information, triggering alert messages to prevent accidents by notifying drivers of potentially hazardous driving conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic technology is adopted to detect driver fatigue, then driver safety is improved, but device complexity increases
Solution Approach 1:
The system divides driver fatigue detection into multiple independent detection modules: steering wheel turn detection, head-swing detection via ultrasonic transceivers, and alert generation. Each module operates independently but contributes to the overall fatigue detection function, making the complex system more manageable and reliable
Solution Approach 2:
The alert system serves multiple functions: it detects steering wheel turns, monitors head position via ultrasonic transceivers, generates alert signals, and provides visual/audio warnings. This multi-functionality consolidates what would otherwise require separate systems into one integrated solution
2Measurement precision
If multiple detection methods are used to improve detection accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines steering wheel turn detection and head-swing detection into a unified fatigue detection system. The controller integrates data from both the turn detector and ultrasonic transceivers to generate comprehensive alert signals, improving detection accuracy while avoiding the complexity of completely separate systems
Solution Approach 2:
The controller acts as an intermediary that processes information from multiple detection sources (turn detector, ultrasonic transceivers) and coordinates their outputs. This mediator component allows different detection methods to work together seamlessly without requiring direct complex interactions between them

Data Source
AI summary
An alert method and an alert system thereof. The alert method includes: detecting, by a turn detector installed on a steering wheel, a first turn and a second turn of the steering wheel in a predetermined period; generating, by a controller, a first alert signal based on the first and second turns; and when receiving the first alert signal, generating, by an alert device, a first alert message.
