V2X Obstacle Alert Filtering by Relative Distance and Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-everything (V2X) communication systems lack the ability to provide drivers with information tailored to the appropriate level of countermeasures needed based on the relative distance and direction of obstacles, potentially leading to decreased driver attentiveness and distrust due to irrelevant alerts.
Innovation Solution
An information processing apparatus and method that calculates relative distances and directions of obstacles using V2X communication, determining the necessity and type of alerts based on these factors to inform drivers appropriately, using different alert levels and methods (e.g., display colors, sound tones) to differentiate the importance of the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2X communication systems provide frequent obstacle alerts to ensure driver awareness, then driver safety awareness is improved, but driver distrust and attentiveness decrease due to irrelevant alerts
Solution Approach 1:
The notification system applies different notification characteristics based on the specific situation parameters (distance, direction, obstacle type). By making the notification properties local to each situation rather than uniform, the system provides relevant alerts only when necessary, maintaining driver trust and attentiveness while ensuring safety awareness.
Solution Approach 2:
The system changes notification parameters (whether to notify, notification timing, and notification intensity) based on calculated situation parameters such as relative distance, direction, and obstacle type. This dynamic parameter adjustment ensures notifications are appropriate to the threat level, preventing both over-notification and under-notification.
2Loss of information
If V2X communication systems notify drivers of all obstacles to ensure comprehensive awareness, then information completeness is improved, but driver distrust increases due to irrelevant information
Solution Approach 1:
The system selectively provides information based on the specific characteristics of each obstacle situation. Rather than uniform notification of all obstacles, it applies different notification strategies based on distance, direction, and obstacle type, ensuring information completeness for relevant cases while filtering out irrelevant information to maintain driver trust.
Solution Approach 2:
The system performs partial notification action by determining whether notification is necessary based on calculated parameters. It avoids excessive notification of irrelevant obstacles while ensuring complete information provision for obstacles that require driver awareness, balancing information completeness with driver trust.
3Measurement precision
If the system calculates detailed relative distance and direction for each obstacle, then notification accuracy is improved, but processing complexity increases
Solution Approach 1:
The notification determination process is segmented into distinct calculation steps: calculating relative distance, calculating direction, determining obstacle type, and then determining notification necessity. This segmentation of the processing workflow makes the complex determination process more manageable and systematic while maintaining high notification accuracy.

AI summary
An information processing apparatus is provided on a first vehicle that is a connected vehicle capable of performing V2X (Vehicle-to-Everything) communication. The information processing apparatus has a controller. The controller receives first information including location information of a first object. The controller calculates a first distance based on the location information included in the first information. The first distance is the relative distance between the first object and the first vehicle along a first direction that is perpendicular to the direction of travel of the first vehicle. The controller determines whether or not it is necessary to output second information to caution about the first object based on the first distance.
