V2X Vehicle Image Output Device for Non-V2X Safety Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional V2X technologies fail to provide effective safety services to vehicles and pedestrians without a V2X device, as they cannot communicate or detect non-V2X entities effectively.
Innovation Solution
A method using an image output device on a V2X vehicle to detect objects and transmit safety messages, including visual alerts for braking and collision prevention, to both V2X and non-V2X vehicles and pedestrians through a wireless communication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional V2X communication methods are used, then safety services can be provided between V2X-equipped vehicles and devices, but safety services cannot be provided to vehicles or pedestrians without V2X devices
Solution Approach 1:
The patent introduces an image output device as an intermediary that translates V2X detection data into visual signals that non-V2X vehicles and pedestrians can perceive. The image output device displays visual representations of detected objects (vehicles, pedestrians, cyclists) and their states (moving, stationary, collision risk), serving as a mediator between the V2X communication system and non-V2X road users. This allows the host vehicle to provide safety information to entities that cannot receive or transmit V2X messages directly.
2Reliability
If visual warnings are provided to all road users including non-V2X vehicles, then safety service coverage is improved, but the device complexity increases due to the image output device
Solution Approach 1:
The image output device serves multiple functions: it displays visual warnings to non-V2X vehicles, provides feedback to the driver about detected objects, and can show navigation or safety information. By making this single device multi-functional, the patent reduces the need for separate dedicated display systems for different purposes, thereby mitigating the increase in device complexity while maintaining comprehensive safety coverage.

AI summary
Provided is a method for providing a safety service in a wireless communication system via a host vehicle. The method may include: detecting an object outside the host vehicle through an object detection device; transmitting a first message providing notification of the detection of the object through a transmitter and a receiver; and outputting an image, for providing the object with the safety service, through an image output device to a prescribed area outside the host vehicle.
