Vehicle Navigation Map Filtering by Car Model for Secure Social Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems fail to encourage interaction among complete strangers by requiring users to be friends before generating route candidates via shooting locations of moving image data, limiting social interaction among users with different car models.
Innovation Solution
A vehicle-mounted device and server system that detects and transmits vehicle positions, displays positions of same car model vehicles on a map, and filters vehicles based on security criteria to prevent abuse, allowing interaction among owners of specific car models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the navigation system requires users to be friends before generating route candidates via shooting locations, then user privacy and security are protected, but social interaction among complete strangers is limited
Solution Approach 1:
The system segments users by car model type, creating separate interaction groups. Users can only see and interact with vehicles of the same car model, which divides the user base into manageable segments that maintain security while enabling targeted social interaction. This is implemented through the map information generation unit that filters and displays only same-model vehicles on the navigation map.
Solution Approach 2:
The system introduces car model classification as an intermediary layer between complete strangers. Instead of requiring direct friend connections, the car model acts as a mediator that enables indirect interaction. Users interact through the shared characteristic of their car model rather than having direct personal connections, solving the contradiction between security and social interaction.
2Loss of information
If the system displays all vehicle positions on the map, then complete visibility is achieved, but security risks such as vehicle theft increase
Solution Approach 1:
The system applies local quality by making map visibility selective rather than universal. Instead of displaying all vehicles uniformly, it displays only vehicles of the same car model with the same identification to each user. This localized visibility approach maintains security by limiting exposure while providing sufficient information for the intended interaction purpose.
Solution Approach 2:
The system changes the parameter of map display from showing all vehicles to showing only same-model vehicles. The map information generation unit modifies the display parameters to filter vehicles based on car model classification, thereby reducing security risks while maintaining useful visibility for the navigation and social interaction functions.
3Reliability
If the system filters vehicles by car model, then security is improved by preventing abuse, but interaction among different car model owners is reduced
Solution Approach 1:
The system segments the user population by car model, creating distinct interaction zones. Each user interacts only within their car model segment, which provides security through isolation while maintaining interaction capability within the segment. The navigation map displays separate clusters of same-model vehicles, enabling focused social interaction without cross-model confusion or security risks.

AI summary
A vehicle-mounted device that includes: a memory; and a processor, wherein the processor is configured to: detect an own vehicle position; transmit position information that indicates the detected own vehicle position to a location outside the own vehicle, together with car model information that indicates a car model of the own vehicle; receive position information of another vehicle of a predetermined specific car model or map information that indicates a position of the other vehicle, from the location outside the own vehicle; and display the position of the other vehicle on a monitor as a map, based on a reception result.
