Solution Overview

Problem

Existing vehicle display systems fail to effectively suppress distractions to drivers when displaying various information in front of the driver's seat, particularly in regions that may divert the driver's attention, leading to potential safety hazards.

Innovation Solution

A vehicle display control device that acquires position information of detection objects ahead, generates images indicating directions, and limits displays in specific regions to reduce distractions by controlling the display based on entropy and reference heights, ensuring the image is not in regions that could divert the driver's attention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple images are displayed on the display area to provide comprehensive vehicle surrounding information, then the information completeness is improved, but the driver distraction risk increases

Engineering Contradiction:
Improvevehicle surrounding information completenessVSAvoiddriver distraction
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by displaying images with different transparency levels in different spatial regions. Specifically, images in the upper display region (above reference height) are displayed with lower transparency to reduce distraction, while images in the lower display region (below reference height) are displayed with higher transparency to maintain information visibility. This spatial differentiation of display properties resolves the contradiction between information completeness and driver distraction.

Inventive Principle:
Principle #3Local quality

2Loss of information

If images are displayed in the upper region of the display area, then the entropy of information is reduced, but the driver's notice of obstructions may be delayed

Engineering Contradiction:
Improveinformation entropyVSAvoidobstruction notice time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent resolves this contradiction by introducing a vertical dimension to the display strategy. Instead of uniformly displaying images across the horizontal display area, the system divides the display area into upper and lower regions based on reference height. Images are selectively displayed in the lower region where they are less likely to obscure obstruction views, while the upper region is used for information that can tolerate reduced visibility. This dimensional separation allows information to be displayed without significantly delaying obstruction notice.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A vehicle display control device acquires position information of a detection object ahead of a vehicle. The vehicle display control device generates an image indicating a direction from the vehicle toward the detection object based on the acquired position information of the detection object. When the generated image is displayed on a display area in front of a driver's seat of the vehicle, the vehicle display control device causes display of the image overlaid on a forward scene of the vehicle while limiting display of the image in a specific region inside the display area.
