Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle display systems fail to effectively inform occupants of driving operation interventions during autonomous driving, potentially causing discomfort to other occupants due to unintentional override operations.

Innovation Solution

A vehicle display control device that detects driving operation interventions during autonomous driving and changes background information on the display to visually alert the occupant, including features like toned-down images and warning messages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If voice messages are used to report driving operation interventions to the vehicle occupant, then the information can be transmitted quickly, but the comfort of other vehicle occupants is disturbed

Engineering Contradiction:

Improvetime to report driving operation interventionVSAvoiddisturbance to other vehicle occupants

Core Design Contradiction:

Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the acoustic notification system (voice messages) with a visual notification system (display unit showing background information changes). This substitution eliminates the harmful acoustic disturbance to other occupants while maintaining the time-efficient notification function through visual cues on the display unit.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The display unit serves as an intermediary between the driving operation intervention detection and the vehicle occupant. Instead of directly notifying the occupant through voice messages that disturb others, the system uses the display unit to convey information through visual changes in background information, thereby mediating the notification process to avoid harmful effects.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A vehicle display control device includes: a driving mode acquisition section that acquires information on which of a manual driving mode or an autonomous driving mode is a driving mode; an operation intervention detection section that, in a case in which the driving mode acquired by the driving mode acquisition section is the autonomous driving mode, detects a driving operation intervention by the vehicle occupant; and a display control section that displays vicinity information of the vehicle at a display unit provided at a vehicle cabin at least in a case in which the driving mode acquired by the driving mode acquisition section is the autonomous driving mode, wherein, in a case in which a driving operation intervention is detected by the operation intervention detection section, the display control section changes background information of the vicinity information and displays the background information at the display unit.
