Vehicle Notification Device for Blind Spot Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems struggle to effectively inform entering vehicles of situations around the notification vehicle, particularly in scenarios where the entering vehicle may pass in front of the notification vehicle, leading to potential blind spots and difficulties in recognizing surrounding vehicles.
Innovation Solution
A notification device equipped in vehicles that includes a recognition unit to identify surrounding vehicles, a determination unit to determine if an entering vehicle is approaching, and a notification control unit to inform the entering vehicle of its surroundings, including those in blind spots, using external sensors and display devices positioned for visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the notification vehicle notifies only the entering vehicle of its presence, then the entering vehicle can recognize the notification vehicle, but the entering vehicle cannot grasp the situation of other surrounding vehicles in blind spots
Solution Approach 1:
The notification vehicle acts as an intermediary between surrounding vehicles (including those in blind spots) and the entering vehicle. Sensors on the notification vehicle detect surrounding vehicles and transmit this information to the entering vehicle through notification devices, enabling the entering vehicle to grasp situations it cannot directly observe
Solution Approach 2:
The notification system is designed to notify multiple types of vehicles (entering vehicles, vehicles in blind spots, vehicles in opposite lanes) with comprehensive surrounding vehicle information, making the system universally applicable to various traffic scenarios rather than serving a single function
2Reliability
If the notification system provides comprehensive information on all surrounding vehicles, then the entering vehicle can grasp the complete situation, but the notification system becomes more complex
Solution Approach 1:
The notification system segments information transmission by identifying and notifying different vehicle types (entering vehicles, vehicles in blind spots, vehicles in opposite lanes) with tailored information relevant to their specific situations, rather than providing uniform comprehensive information to all vehicles
Solution Approach 2:
The notification vehicle serves as a mediator that processes sensor data, determines which surrounding vehicles need notification, and transmits appropriate information to relevant vehicles, reducing the complexity that would arise from direct peer-to-peer communication between all vehicles

AI summary
A notification device includes a recognition unit configured to recognize a plurality of surrounding vehicles, a notification unit configured to provide information as a notification toward an outside of a vehicle, a determination unit configured to determine whether or not at least one of the plurality of surrounding vehicles recognized by the recognition unit is an entering vehicle going to pass in front of the vehicle, and a notification control unit configured to cause the notification unit to notify the entering vehicle of a recognition result of the recognition unit when the determination unit determines that at least one of the plurality of surrounding vehicles is the entering vehicle.
