V2X Communication Device Map Alert System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-everything (V2X) communication systems lack effective methods to accurately inform drivers of potential collisions with pedestrians or vehicles, especially in complex traffic scenarios, leading to safety concerns.
Innovation Solution
A communication device mounted on a moving body that receives and processes V2X information to determine the necessity of providing safety services, such as collision prevention support, by displaying relevant information on a map, including icons or characters indicating the presence of pedestrians or vehicles, thereby enhancing driver awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2X communication information is received and processed to determine collision risks, then driver safety is improved, but device complexity increases
Solution Approach 1:
The communication device is divided into distinct functional units: a communication unit for receiving V2X information, a determination unit for assessing collision risks, and a display controller for presenting alerts. This segmentation allows each component to perform its specific function efficiently, improving overall system reliability while managing complexity through modular design
Solution Approach 2:
The determination unit acts as an intermediary between the communication unit and the display controller. It processes raw V2X communication information, evaluates collision risks, and generates appropriate alert signals. This intermediary layer simplifies the system by centralizing the decision-making logic and preventing direct complex interactions between communication and display subsystems
2Loss of information
If display information is shown on a map to indicate potential collisions, then driver awareness is improved, but information processing time increases
Solution Approach 1:
The system performs preliminary determination of collision risks using V2X communication data before displaying alerts on the map. By pre-processing communication information and identifying potential hazards in advance, the system prepares alert data ready for immediate display, reducing the time required to present critical information to the driver
Solution Approach 2:
The display controller shows alert information at specific locations on the map corresponding to the spatial position of potential collision risks. Rather than processing and displaying all possible information uniformly, the system focuses display resources on locally relevant alert information, improving driver awareness of specific hazards while minimizing unnecessary processing time

AI summary
A communication device accurately reports the position a vehicle or a pedestrian with respect to a local vehicle and supports safer driving. The communication device is mounted on a moving body and includes a communication unit that receives communication information according to a preset communication condition, a determination unit that determines whether a service is provided in accordance with the received communication information and a display controller that displays display information needed to provide the service on a map displayed on a display unit, when the service is provided according to a result determined by the determination unit.
