Reckless Vehicle Detection via Distinct Display Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inter-vehicle communication systems cannot effectively notify drivers about nearby vehicles engaging in reckless driving, as they only display positions and travel directions without indicating safe or unsafe driving behaviors.
Innovation Solution
A reckless-vehicle reporting apparatus that wirelessly communicates with other vehicles to detect and display reckless driving behavior using a position detection unit, in-vehicle communicator, determination information acquisition, and display processors, allowing drivers to identify potentially reckless vehicles through distinct display modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If inter-vehicle communication is used to display position and travel direction of nearby vehicles, then drivers can see the location of other vehicles, but the system cannot determine or report whether the nearby vehicles are being driven recklessly
Solution Approach 1:
The system performs preliminary determination of reckless driving behavior by analyzing acceleration, orientation angle speed, and travel speed data before transmitting this information to other vehicles. This allows the driving behavior assessment to be completed in advance, enabling other drivers to receive and act on this information without causing system complexity or communication delays.
2Reliability
If the system transmits and processes determination information from multiple vehicles, then reckless driving can be identified, but the communication data load and processing complexity increase
Solution Approach 1:
The system extracts only the essential determination information needed for reckless driving identification (acceleration, orientation angle speed, travel speed) from the vehicle data, separating these critical parameters from other unnecessary data. This extraction approach enables reliable reckless vehicle identification while minimizing communication data load and processing complexity.
3Loss of information
If all nearby vehicles are displayed with the same mark, then the display is simple, but drivers cannot distinguish reckless vehicles from normal vehicles
Solution Approach 1:
The system changes the color or appearance of display marks based on the determined driving behavior of nearby vehicles. Reckless vehicles are displayed with distinct visual characteristics (such as different colors or flashing patterns) compared to normal vehicles, enabling drivers to quickly distinguish and respond to potential hazards without complex information processing.
Data Source
AI summary
A reckless-vehicle determination section of a vehicle determines whether a reckless driving operation takes place in each of different vehicles based on determination information from each of the different vehicles. A target different vehicle in which a reckless driving operation is determined to take place is displayed on a display in a display mode that is different from that for any different vehicle in which a reckless driving operation is not determined to take place.
