V2V Abnormal Vehicle Detection for Emergency Control Decisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle-to-vehicle communication systems lack a direct method for providing objective information on abnormal vehicle behavior from one vehicle to another, which can impact traveling safety.
Innovation Solution
A vehicle control system and method that enables direct vehicle-to-vehicle communication between a host vehicle and another vehicle, where the latter performs objective determination processing to assess the host vehicle's abnormal behavior based on driving environment information and sends the result for emergency control, optionally combining with subjective determination from the host vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a server is used to detect abnormal vehicles and provide information, then information can be provided to vehicles, but the system complexity increases and response time is delayed
Solution Approach 1:
The patent extracts the abnormal vehicle detection function from the central server and relocates it to individual vehicles. Each vehicle independently performs detection using its own sensors and processors, eliminating the need for complex server-based statistical processing while maintaining detection capability.
Solution Approach 2:
Vehicles perform self-detection and self-assessment of abnormal behavior using their own sensing capabilities and processors. Each vehicle independently determines whether it or other vehicles are exhibiting abnormal behavior, reducing reliance on external server infrastructure.
2Reliability
If a server is used to process behavior information, then abnormal vehicles can be detected, but the response time is delayed
Solution Approach 1:
Vehicles continuously collect and pre-process behavior information using their own sensors and processors in real-time. This preliminary action enables immediate detection and response to abnormal behavior without waiting for server processing, significantly reducing response time.
Solution Approach 2:
Each vehicle independently performs real-time detection and assessment of abnormal behavior using its own computational resources, eliminating the time delay associated with server communication and processing.
3Reliability
If V2V communication is used to provide objective determination results, then traveling safety is improved, but the need for subjective determination from the host vehicle reduces
Solution Approach 1:
The patent merges objective determination results from other vehicles with subjective determination from the host vehicle through V2V communication. The host vehicle's processor integrates both types of determination to make a comprehensive abnormal behavior assessment, combining external objective data with internal subjective analysis.
Solution Approach 2:
V2V communication establishes a feedback loop where objective determination results from other vehicles are transmitted to the host vehicle. This feedback enables the host vehicle to adjust its determination processing by comparing its subjective assessment with objective data from the network, improving overall detection accuracy.

AI summary
A first vehicle includes a communication device configured to send and receive V2V information, a memory configured to store the V2V information, and a processor configured to perform abnormal traveling determination processing. A second vehicle includes a communication device configured to send and receive the V2V information, a memory configured to store the V2V information and driving environment information on the second vehicle, and a processor configured to perform objective determination processing. In the objective determination processing, whether the first vehicle is traveling abnormally is objectively determined based on the driving environment information on the second vehicle. The determination result of the objective determination processing is sent to the first vehicle. In the abnormal traveling determination processing, whether the first vehicle is traveling abnormally is determined based on this determination result. When the first vehicle is determined to be traveling abnormally, emergency vehicle control is performed for the first vehicle.
