Vehicle Display Mode Switching for Autonomous Driving Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information presentation systems for autonomous driving only display information recognized by the vehicle, failing to inform occupants about the operating status and settings of the autonomous driving system, limiting their understanding of the system's operation.
Innovation Solution
An information presentation system that includes a display unit, a display control unit, and an acquisition unit, allowing occupants to switch between setting status, operation status, and recognition status display modes, enabling the presentation of recognition information in association with setting and travel information based on occupant instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system displays only recognition information, then the driver's attention is directed to unrecognized areas, but occupants cannot understand the autonomous driving system's operation status and settings
Solution Approach 1:
The display information is segmented into three distinct display modes: setting status display mode (showing autonomous driving settings), operation status display mode (showing travel information), and recognition status display mode (showing recognition results). This segmentation allows occupants to selectively view different aspects of system operation without overwhelming them with all information simultaneously, resolving the contradiction between information completeness and display manageability.
Solution Approach 2:
The display unit is designed to perform multiple functions by switching between different display modes based on occupant instructions. The same display hardware can present setting information, operation status, or recognition results as needed, making the system universal in its information presentation capabilities while maintaining simple hardware architecture.
2Loss of information
If the system provides comprehensive information about autonomous driving operation, then occupants gain full understanding, but the display becomes overly complex and difficult to operate
Solution Approach 1:
The display mode is made dynamic and adjustable based on occupant needs. The acquisition unit detects occupant instructions (such as button presses or touch inputs) and the display control unit dynamically switches between display modes accordingly. This dynamic adaptability allows the system to provide comprehensive information when needed while maintaining ease of operation through simple switching mechanisms.
Solution Approach 2:
The system incorporates feedback mechanisms where the acquisition unit detects occupant instructions and feeds this information back to the display control unit, which then adjusts the display mode. This feedback loop enables the system to respond to occupant needs in real-time, providing comprehensive information when requested while maintaining simple operation through intuitive feedback-based control.

AI summary
A system for presenting information to an occupant of a vehicle mounted with an autonomous driving system, includes: a display unit configured to display the information; a display control unit configured to cause the display unit to display information in any one of display modes among a setting status display mode in which setting information is displayed, an operation status display mode in which travel information is displayed, and a recognition status display mode in which recognition result information of the autonomous driving system is displayed; and an acquisition unit configured to acquire an occupant's display mode switching instruction for switching the display mode, wherein the display control unit configured to switch the display mode of the display unit when the acquisition unit acquires the occupant's display mode switching instruction.
