Autonomous Driving Control Right Transfer Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving control systems inaccurately identify user drowsiness, leading to unnecessary control right transfer notifications and increased power consumption, as they may mistakenly recognize users interacting with multimedia devices as drowsy.
Innovation Solution
A device and method that utilize sensors to monitor user state and determine the presence of external device connections and user input, providing control right transfer interfaces only when necessary, using display devices and communication with external devices to ensure accurate notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous driving control device monitors user state using sensors to identify drowsiness, then the reliability of control right transfer notification is improved, but false identification of drowsy state occurs when user is using multimedia devices, leading to unnecessary notifications
Solution Approach 1:
The monitoring system is divided into multiple independent sensor modules: posture detection sensors, multimedia device usage detection sensors, and external device connection detection sensors. Each sensor group independently monitors specific aspects of user state, and their results are integrated to make comprehensive drowsiness determination, reducing false positives from single-sensor limitations
Solution Approach 2:
The system continuously receives feedback from multiple sensors about user posture, multimedia device usage status, and external device connection status. This feedback loop allows the system to dynamically adjust its drowsiness assessment by cross-validating signals from different sources, preventing false identification when user is engaged with devices
2Reliability
If the autonomous driving control device provides control right transfer notification frequently to ensure safety, then the reliability of safety monitoring is improved, but user experience deteriorates due to unnecessary notifications
Solution Approach 1:
The system performs preliminary verification of user state using multiple sensors before triggering control right transfer notification. By checking multimedia device usage status, external device connections, and posture data in advance, the system prevents unnecessary notifications while maintaining safety monitoring, improving user experience without compromising reliability
3Reliability
If the autonomous driving control device continuously monitors user state and provides notifications, then the reliability of control right management is improved, but power consumption increases
Solution Approach 1:
The system implements periodic monitoring cycles where sensors are activated at intervals rather than continuously. The control unit checks user state, multimedia device usage, and external device connections at predetermined time periods, maintaining control right management reliability while significantly reducing power consumption compared to continuous monitoring
