Vehicular Location Display System Selective Data Filtering

Solution Overview

Problem

Vehicular communication devices, when connected with portable communication terminals for location information sharing, face issues such as slower screen processing and lower data transfer rates, leading to inefficient display of user locations, including wasteful display of remote users' icons and long loading times for multiple icons.

Innovation Solution

The portable communication terminal selectively transmits location information to the vehicular communication device based on acquired selection conditions, such as maximum number of displayable users, display range, and data transfer volume, to optimize icon display on the vehicular device's map screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If location information of all users is transmitted to the vehicular communication device, then the completeness of location information is improved, but the processing time and data transfer time increase significantly

Engineering Contradiction:

Improvecompleteness of location informationVSAvoidprocessing time and data transfer time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent extracts only the necessary location information (selected users within display range) from the complete set of user location data. The portable communication terminal filters and transmits only relevant location information to the vehicular communication device, eliminating unnecessary data transmission and processing time.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the complete set of user location information into multiple groups based on selection conditions (display range, user importance, etc.). Only specific segments (selected users) are transmitted to the vehicular communication device, reducing overall data volume while maintaining essential information completeness.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If location information of all users is transmitted to the vehicular communication device, then the completeness of location information is improved, but data transfer volume increases

Engineering Contradiction:

Improvecompleteness of location informationVSAvoiddata transfer volume

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary location information (selected users within display range) from the complete set of user location data. The portable communication terminal filters and transmits only relevant location information to the vehicular communication device, eliminating unnecessary data transmission and processing time.

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the complete set of user location information into multiple groups based on selection conditions (display range, user importance, etc.). Only specific segments (selected users) are transmitted to the vehicular communication device, reducing overall data volume while maintaining essential information completeness.

Inventive Principle:

Principle #1Segmentation

3Loss of information

If icons of all users are displayed on the map screen, then the completeness of location display is improved, but the visibility of individual icons deteriorates

Engineering Contradiction:

Improvecompleteness of location displayVSAvoidvisibility of icons

Core Design Contradiction:

Loss of informationVSIllumination intensity

Solution Approach 1:

The patent extracts only the necessary location information (selected users within display range) from the complete set of user location data. The portable communication terminal filters and transmits only relevant location information to the vehicular communication device, eliminating unnecessary data transmission and processing time.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different display priorities to different users based on their importance and proximity. High-priority users (e.g., family members, close contacts) are displayed with higher visibility, while low-priority users are excluded or displayed with lower prominence, optimizing the overall display quality.

Inventive Principle:

Principle #3Local quality

AI summary

A location information display system includes a portable communication terminal receiving location information of respective users belonging to a predetermined group from a server, and a vehicular communication device receiving the location information from the portable communication terminal and displaying icons indicating present locations of the respective users identified based on the received location information by superimposing the icons on a map screen. The vehicular communication device notifies the portable communication terminal of a selection condition. The portable communication terminal acquires the selection condition from the vehicular communication device, selects one or more users who satisfy the acquired selection condition, and transmits the location information of the selected users to the vehicular communication device.
