V2V Fall Notification for Flying Device Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively reduce damage to vehicles caused by falling flying devices due to the lack of widespread implementation of direct notification systems, as frequent falling events are uncommon, limiting the use of specialized receivers for such notifications.
Innovation Solution
A fall damage reducing system comprising a flying device and vehicle-mounted device that utilize vehicle-to-vehicle communication standards to transmit and receive falling information, enabling vehicles to perform collision avoidance processes and reduce damage through coordinated vehicle controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct notification systems with specialized receivers are implemented, then fall damage reduction capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by enabling vehicle-to-vehicle communication systems to serve dual purposes: their original function for vehicle coordination and an additional function for receiving fall risk notifications from flying devices. This eliminates the need for specialized receivers by using existing communication infrastructure for multiple functions, thereby reducing device complexity while maintaining fall damage reduction capability.
Solution Approach 2:
The system allows vehicles to autonomously determine and execute avoidance maneuvers when fall risk is detected, without requiring external control systems or specialized intervention equipment. The vehicle's existing communication and control systems are leveraged to automatically receive notifications and perform avoidance actions, reducing the need for additional specialized components.
2Adaptability or versatility
If vehicle-to-vehicle communication is used for fall notification, then adaptability and coverage are improved, but information loss and communication reliability worsen
Solution Approach 1:
The patent implements feedback mechanisms where vehicles confirm receipt and processing of fall information, allowing the system to track information transmission status. This feedback loop helps ensure information integrity across the communication network and enables retransmission or alternative notification methods if information loss is detected, maintaining accuracy while expanding coverage.
3Reliability
If vehicles perform avoidance maneuvers upon receiving fall information, then fall damage is reduced, but collision risk with other vehicles increases
Solution Approach 1:
The patent introduces vehicle-to-vehicle communication as an intermediary layer that coordinates avoidance maneuvers between multiple vehicles. When one vehicle receives fall information and plans an avoidance maneuver, it communicates this intent to surrounding vehicles through V2V communication, allowing them to adjust their paths accordingly. This mediator communication system coordinates the avoidance actions to reduce individual fall damage risk while minimizing collective collision risk.

AI summary
A fall damage reducing system includes a flying device and a vehicle-mounted device. The flying device: performs a wireless communication under a vehicle to vehicle communication standard; determines a falling possibility of the flying device; and transmits falling information indicating an estimated falling position of the flying device in response to the falling possibility being determined. The vehicle-mounted device: performs a wireless communication under the vehicle to vehicle communication standard; executes a vehicle control on a subject vehicle to avoid the estimated falling position in response to the falling information being received; and transmits traveling information indicating the vehicle control executed on the subject vehicle. In response to the traveling information from a different vehicle being received, the vehicle-mounted device executes a collision avoidance process to avoid a collision with the different vehicle.
