Vehicle Display Mode Switching for Autonomous Driving Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In four-wheel drive vehicles, existing display systems do not adequately adapt to switch between manual and autonomous driving modes, failing to provide the desired information to occupants during autonomous driving.
Innovation Solution
A display control device that switches between display modes based on the vehicle's driving mode, prioritizing statistics such as average fuel consumption and vehicle speed in autonomous mode, rather than real-time vehicle states, to enhance occupant satisfaction and understanding of autonomous driving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display unit continuously shows real-time vehicle state information (first category display mode) during autonomous driving, then the driver can monitor current vehicle status, but the display does not provide statistically meaningful information for evaluating autonomous driving performance
Solution Approach 1:
The display control device dynamically switches between first category display mode (real-time vehicle state) and second category display mode (statistical information) based on the detected traveling mode. When autonomous driving is detected, the system transitions to displaying statistical information such as average fuel consumption and average vehicle speed, making the display adaptable to different operational contexts and providing occupant-centric information for evaluating autonomous driving performance.
2Loss of information
If the display unit shows driving force distribution information (first category display mode) during autonomous driving, then real-time drive wheel control information is provided, but the occupant cannot assess the overall appropriateness of autonomous driving results
Solution Approach 1:
The display control device performs preliminary detection of the traveling mode and proactively switches to the appropriate display mode before the occupant needs to evaluate autonomous driving performance. By detecting autonomous driving mode in advance and pre-loading statistical information display, the system eliminates the need for complex real-time mode switching decisions and provides evaluation information promptly.
3Ease of operation
If the display control device maintains the same display mode across different traveling modes, then the system is simple to operate, but the display does not provide desired information to occupants during autonomous driving
Solution Approach 1:
The display control device implements a feedback mechanism by detecting the traveling mode (manual or autonomous) and using this information to automatically adjust the display mode. This closed-loop control ensures that the display always shows information relevant to the current operational context without requiring complex manual configuration, thereby improving ease of operation while maintaining display relevance.

AI summary
A display control device provided in a vehicle includes a display unit that has an automatic driving mode or a manual driving mode as a driving mode and displays information to an occupant, and the display control device controls the display unit to display a plurality of types of display modes including a first type display mode that displays a state of the vehicle at the time of display and a second type display mode that does not display a state of the vehicle at the time of display, and displays a second type display mode at the time of display when a predetermined first condition is satisfied including that a driving mode is switched from a manual driving mode in which a display according to the first type display mode is performed in the display unit to an automatic driving mode.
