Driver Assistance Alerts for Autonomous Mode Call Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems do not effectively manage communication disruptions during transitions from autonomous driving modes, failing to notify drivers and interlocutors of impending mode changes and resulting communication interruptions.
Innovation Solution
A method that detects ongoing communication and impending deactivation of autonomous driving modes, alerts the driver and interlocutor of the duration of deactivation, activates a second driving mode, and allows the interlocutor to record messages, ensuring seamless communication transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver assistance system transitions from autonomous driving mode to manual mode, then the driver's safety and control are improved, but the ongoing communication with the interlocutor is interrupted
Solution Approach 1:
The system performs preliminary actions by detecting the transition condition in advance and sending alert messages to the interlocutor before the actual mode transition occurs. This allows the communication to be properly concluded or transferred before the driver must take control, preventing abrupt interruption and information loss.
Solution Approach 2:
The system establishes a feedback loop where the driver assistance system monitors both driving conditions and communication status, then provides feedback to the interlocutor about the upcoming transition. This feedback mechanism ensures the interlocutor is informed and can adjust accordingly, maintaining communication quality.
2Ease of operation
If the system sends multiple alert messages to the driver and interlocutor, then the communication transition is smoothed, but the system complexity increases
Solution Approach 1:
The driver assistance system performs multiple functions: it monitors driving conditions, detects mode transitions, manages communication status, generates alert messages, and sends notifications to the interlocutor. By making the system universal and multi-functional, the patent avoids adding separate dedicated components for each function, thus managing complexity while achieving smooth communication transitions.
Solution Approach 2:
The patent combines the transition management and communication management functions into a unified process. The alert message generation and sending is merged with the existing mode transition logic, rather than being a separate independent system. This merging reduces overall system complexity while maintaining the ability to smoothly manage communication transitions.
