Solution Overview

Problem

Current detectors are inefficient in detecting misbehaving vehicles in V2X communications, particularly those that create non-visible ghost objects, leading to unnecessary vehicle maneuvers and traffic disruptions.

Innovation Solution

A misbehavior detection service utilizing V2X communications to verify the physical existence of objects through line-of-sight confirmation and data redundancy, allowing sensor-sharing between V2X-capable network devices to confirm the presence of ghost objects and ensure accurate situational awareness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current detectors are used to detect misbehaving vehicles in V2X communications, then the detection process is simple, but the detection efficiency is low and ghost objects cannot be identified

Engineering Contradiction:
Improvedetection efficiencyVSAvoiddetection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple data sources (sensor data from multiple vehicles, map data, historical data) into a unified detection system. The fusion center integrates information from various detectors and external sources to create a comprehensive view, enabling reliable detection of ghost objects while distributing computational complexity across the network rather than concentrating it in a single device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a fusion center as an intermediary between individual vehicle detectors and the central authority. This intermediary aggregates data from multiple sources, performs cross-verification, and generates consolidated detection results, thereby improving detection efficiency without requiring each vehicle to independently process all detection algorithms.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If detectors operate independently without data sharing, then device complexity is low, but detection accuracy decreases and ghost objects remain undetected

Engineering Contradiction:
Improvedetection accuracyVSAvoiddata sharing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a universal detection framework where sensor data serves multiple purposes: individual vehicle detection, cross-verification against map data, historical pattern matching, and ghost object identification. The same data infrastructure supports multiple detection functions simultaneously, improving accuracy without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements feedback loops where detection results from multiple sources are continuously compared and verified. The fusion center receives ongoing data streams, cross-checks them against each other and against stored map/historical data, and adjusts detection confidence levels based on consistency across sources, thereby improving accuracy through iterative verification.

Inventive Principle:
Principle #23Feedback

3Reliability

If line-of-sight confirmation and data redundancy are implemented, then ghost object verification improves, but communication overhead increases

Engineering Contradiction:
Improveghost object verificationVSAvoidcommunication overhead
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies partial verification by selecting only the most relevant data sources for cross-checking rather than exhaustively verifying against all available data. The fusion center prioritizes verification against high-confidence sources (e.g., multiple independent sensors, authoritative map data) and uses probabilistic thresholds to determine when sufficient verification has been achieved, reducing communication overhead while maintaining reliability.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes determining, at the first network device, an estimated location of a second network device. The process may further include comparing, at the first network device, the estimated location with an expected location for the second network device. The process may include determining, at the first network device, whether the second network device is a misbehaving device based on the comparing. The process may further include generating, at the first network device, a report based on the determining of whether the second device is a misbehaving device.
