V2X Obscured Motorcycle Detection at Intersections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycles are often obscured by larger vehicles at intersections, leading to increased accident risk due to drivers and environmental sensors failing to recognize them timely.
Innovation Solution
Implementing vehicle-to-environment messaging to detect obscuration and perform criticality analysis, initiating risk-reducing measures such as warnings or automatic interventions to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motorcycle travels towards a cross-roads, then it can be obscured by a preceding motor vehicle, but the driver and environmental sensors of the second motor vehicle fail to recognize the obscured motorcycle timely
Solution Approach 1:
The patent introduces an intermediary communication system (V2X messaging) that enables the obscured motorcycle to transmit its presence information directly to the second motor vehicle. This intermediary communication channel bypasses the visual and sensor limitations caused by obscuration, allowing the second vehicle to receive direct data about the motorcycle's position and intent without needing to visually detect it.
Solution Approach 2:
The system performs preliminary action by having the obscured motorcycle proactively transmit its status, position, and trajectory information before the second motor vehicle would have a chance to detect it. This advance notification allows the second vehicle to prepare for potential collision risks in advance, rather than reacting after detection fails.
2Reliability
If vehicle-to-environment messaging is implemented to detect obscuration and perform criticality analysis, then collision avoidance is enhanced, but the system complexity increases
Solution Approach 1:
The patent applies universality by utilizing existing V2X communication infrastructure and standard message formats that are already part of the vehicle's communication ecosystem. The same communication interface used for general vehicle-to-environment messaging is leveraged for this specific safety application, avoiding the need for dedicated specialized hardware and reducing overall system complexity.
Solution Approach 2:
The system implements self-service by having the obscured motorcycle autonomously generate and transmit its own presence information without requiring external detection or intervention. The motorcycle's own communication system serves the dual purpose of both detecting its obscured state and notifying other vehicles, eliminating the need for additional external detection devices.

AI summary
Technologies and techniques for reducing a collision risk between a first motor vehicle and a second motor vehicle. At least a first vehicle-to-environment message is transmitted by the first motor vehicle and received by the second motor vehicle. Using a second computing unit of the second motor vehicle, it is determined, depending on the vehicle-to-environment message, whether a risk situation exists in which the first motor vehicle is obscured by a preceding third motor vehicle. The second computing unit executes a criticality analysis to determine that the risk situation exists and, depending on the result of the criticality analysis, a risk-reducing measure is initiated.
