Dual-Cabin Display Layout for Imminent Vehicle Action Alerts

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle display systems overwhelm occupants with a large amount of information, making it time-consuming to identify scheduled vehicle actions, especially during transitions between autonomous and manual driving modes.

Innovation Solution

A vehicle display device comprising a first display inside the cabin for showing a running plan and a second display, such as a head-up display, that highlights impending actions when the distance or time interval to the action reaches a certain threshold, allowing occupants to quickly focus on imminent tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a large amount of information is displayed on a single display device, then the information completeness is improved, but the time required for occupants to identify scheduled actions increases

Engineering Contradiction:

Improveinformation quantityVSAvoididentification time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The display system is divided into two separate display devices: a first display device that shows comprehensive running plan information, and a second display device that highlights only imminent scheduled actions. This segmentation allows occupants to access complete information when needed while quickly identifying urgent actions through the second display, thereby resolving the contradiction between information completeness and identification speed.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If all scheduled actions are displayed on one display, then the information completeness is improved, but the cognitive load on occupants increases

Engineering Contradiction:

Improveinformation completenessVSAvoidcognitive load

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

By segmenting the display function into two devices, the cognitive load is distributed: the first display maintains complete information for reference, while the second display presents only critical imminent actions that require immediate attention. This reduces the mental processing burden on occupants while preserving information accessibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second display device provides localized, high-priority information about imminent scheduled actions with different visual characteristics (such as enhanced visibility or positioning), while the first display maintains comprehensive but less emphasized information. This local quality differentiation helps occupants focus on critical information without being overwhelmed by the complete dataset.

Inventive Principle:

Principle #3Local quality

AI summary

A vehicle display device, that includes: a first display device provided inside a vehicle cabin; a second display device provided inside the vehicle cabin and separately from the first display device; a memory; and a processor connecting to the memory and being configured to: set a running plan of a vehicle, to display a scheduled action of the vehicle on the first display device based on the running plan, and to display the scheduled action on the second display device in a case in which at least one of a distance to, or a time interval until, the scheduled action has reached a prescribed value or less.
