Vehicle Call Speech Mode Indication for Driver Distraction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to adequately prevent driving operations from being disrupted by a vehicle driver participating in an electronic meeting, which is desirable for enhancing traffic safety and convenience, particularly for vulnerable road users.
Innovation Solution
A call support system that includes a call control unit, a speech transmission mode switch unit, and a light emitting part state control unit to manage speech transmission modes and visually indicate the active mode to the user, using light emitting parts to distinguish between permission and prohibition states, thereby minimizing driver distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the driver participates in an electronic meeting using the vehicle's communication system, then communication functionality is improved, but driving safety deteriorates due to driver distraction
Solution Approach 1:
The system provides visual feedback through a light emitting part that indicates the speech transmission mode (permission or prohibition) to the driver. This feedback mechanism helps the driver understand the current system state, reducing cognitive load and distraction while maintaining communication functionality.
Solution Approach 2:
The light emitting part acts as an intermediary between the speech transmission control system and the driver. It provides intuitive visual cues about the system's operational state without requiring the driver to process complex audio or visual interface information, thereby reducing distraction.
2Ease of operation
If speech transmission is always permitted during electronic meetings, then communication quality is improved, but driver distraction increases
Solution Approach 1:
The speech transmission mode is made dynamic rather than static. The system automatically switches between permission and prohibition modes based on vehicle operation state, providing adaptive control that balances communication quality with driving safety without requiring manual driver intervention.
Solution Approach 2:
The system performs self-service by automatically managing speech transmission permissions based on detected vehicle operation states. This eliminates the need for continuous manual control by the driver, reducing distraction while maintaining appropriate communication functionality.
3Ease of operation
If the system provides detailed audio-visual interfaces for meeting control, then ease of use is improved, but driver distraction increases
Solution Approach 1:
The system extracts only the essential information (speech transmission mode status) and presents it through a simple light emitting indicator. Complex meeting control functions are separated from the driving interface, providing ease of use for essential functions while minimizing distraction through simplified presentation.

AI summary
A call support system includes: a speech transmission mode switch unit that switches between a speech transmission permission mode that permits execution of call source speech transmission processing for speech of a user by a call control unit and a speech transmission prohibition mode that prohibits execution of the call source speech transmission processing for the speech of the user by the call control unit; and a light emitting part state control unit that puts a light emitting part, provided in a mobile body to be visible to the user, in a first visible state when the speech transmission permission mode is active, and puts the light emitting part in a second visible state different from the first visible state when the speech transmission prohibition mode is active.
