Server-Based Risk Area Information Storage for Non-Line-of-Sight Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing risk areas in vehicle navigation lack efficient methods for identifying and communicating risk areas to vehicles without advanced sensing capabilities, particularly in situations where the risk area is non-line-of-sight.
Innovation Solution
A system comprising a server that manages position information of risk areas and communicates this information to vehicles, which can then alert passengers and other road users through a wireless communication function, even if the vehicle does not have advanced sensing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a vehicle without advanced sensing capabilities is used, then device complexity is reduced, but the ability to detect non-line-of-sight risk areas deteriorates
Solution Approach 1:
The patent introduces a server as an intermediary between vehicles and risk area detection systems. The server receives risk area information from detection sources (including line-of-sight sensing systems), processes this information, and transmits it to vehicles via wireless communication. This allows vehicles without advanced sensing capabilities to access risk area data through the server intermediary, resolving the contradiction between device complexity and detection capability.
2Reliability
If risk area information is stored and communicated to multiple vehicles, then safety coverage is improved, but information management complexity increases
Solution Approach 1:
The server is designed to perform multiple functions: storing risk area information, managing communication with multiple vehicles, processing detection data, and distributing information to various vehicles. This universal approach allows a single system to serve multiple vehicles simultaneously, improving safety coverage while centralizing information management complexity in the server rather than individual vehicles.

AI summary
A risk area information storage apparatus comprises: a receiving unit which receives position information of a risk area detected by a vehicle, which may pose a risk for the vehicle to travel; a storage unit which stores position information of the risk area in association with link information corresponding to a position of the risk area in map information; and a transmitting unit which transmits to another vehicle position information of the risk area stored by the storage unit in association with link information corresponding to a link along which the another vehicle travels.
