Solution Overview

Problem

Conventional vehicle display systems using rear cameras and side cameras face challenges in fully covering the vehicle's surroundings due to blind spots, making it difficult for drivers to check following moving objects effectively.

Innovation Solution

An on-vehicle display system that includes a rear camera, rear side cameras, and display monitors, which acquires and processes video data to clip and display specific areas, allowing the driver to view blind spots by overlaying additional video data on side monitors when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If side cameras are used instead of side mirrors, then the vehicle can check rear side views, but blind spots still exist due to vehicle reflection in the mirrors

Engineering Contradiction:

Improvesurroundings checking capabilityVSAvoidblind spot coverage

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent divides the video display into multiple segments: the main rear camera view is segmented into a first area (central region) and second areas (side regions). The side monitors display both the second video data from side cameras and clipped portions of the first video data (second areas), creating a segmented display layout that eliminates blind spots while maintaining comprehensive coverage.

Inventive Principle:

Principle #1Segmentation

2Area of stationary object

If the entire first video data is displayed on the rearview monitor, then the rear view is fully visible, but the side monitors cannot display the second video data effectively

Engineering Contradiction:

Improvedisplay area utilizationVSAvoidside view coverage

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The patent extracts specific portions (second areas) from the first video data displayed on the rearview monitor and displays them simultaneously on the side monitors along with the second video data. This extraction allows the side monitors to effectively display side view information without requiring the entire first video data to be displayed on the rearview monitor.

AI summary

An on-vehicle display control device includes a rear video data acquiring unit configured to acquire first video data from a rear camera on a rear part of a vehicle to image a rear view; a rear side video data acquiring unit configured to acquire second video data from rear side cameras on right and left parts of the vehicle to image rear side views, a clipping unit configured to clip a first area that is a part of the first video data and second areas located on right and left sides of the first area, and a display controller configured to display video data clipped as the first area on a rearview monitor to display rear video, display the second video data on side monitors to display rear side video, and display video data clipped as the second area on the side monitors under a predetermined condition.
