Vehicle Display Layout for Noticeable Driving Assist State Changes

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle control systems fail to adequately inform occupants about changes in the state of driving assistance functions, leading to a lack of awareness regarding the activation or deactivation of these functions.

Innovation Solution

A vehicle display control device that displays an ego vehicle image and a function image indicating the action function of the vehicle, with the function image moving or being displayed in a region at the periphery of the ego vehicle image based on changes in the action function state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If both recognized conditions and target track are displayed, then comprehensive information is provided, but occupant awareness of action function state changes is insufficient

Engineering Contradiction:

Improveinformation completenessVSAvoidoccupant awareness

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The display is segmented into distinct functional areas: an ego vehicle image display area showing the vehicle's own image, and a function image display area showing action function states. This segmentation allows comprehensive information to be presented while ensuring that function state changes are visually distinct and easily noticeable, thereby improving occupant awareness without sacrificing information completeness.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If function image is displayed in a fixed position, then display layout is simple, but occupant awareness of state changes is reduced

Engineering Contradiction:

Improvedisplay layout complexityVSAvoidoccupant awareness

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The function image is configured to move within the display region in response to changes in action function states. This dynamic behavior provides visual feedback that immediately captures the occupant's attention, making state changes noticeable without requiring a complex overall display layout. The movement is controlled and purposeful, maintaining simplicity while enhancing awareness.

Inventive Principle:

Principle #15Dynamics

3Loss of information

If multiple images are displayed simultaneously, then comprehensive information is provided, but visual clarity of function state changes is reduced

Engineering Contradiction:

Improveinformation completenessVSAvoidvisual detection of function changes

Core Design Contradiction:

Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The display region is divided into distinct areas with different visual characteristics. The function image display area is positioned and styled to provide visual contrast with the ego vehicle image area. This local differentiation ensures that function state changes are visually prominent and easily detectable, even when multiple images are displayed simultaneously, without sacrificing the completeness of information presented.

Inventive Principle:

Principle #3Local quality

AI summary

A vehicle display control device that is configured to: display an ego vehicle image depicting an ego vehicle, and a function image indicating an action function of the ego vehicle, on a display region provided at a periphery of a driver's seat of the ego vehicle, and display the function image in a region at a periphery of the ego vehicle image so as to move based on a change to a state of the action function.
