Solution Overview

Problem

Conventional systems for real-time monitoring of autonomous vehicles face latency and reliability issues due to limitations in cellular networks, making them unsuitable for efficient and reliable wireless communication of vehicle behavior to other vehicles in the vicinity.

Innovation Solution

A vehicle-to-vehicle (V2V) communication system that uses omnidirectional wireless communication, potentially operating on dedicated short-range communication (DSRC) or C-V2X standards, to broadcast data between autonomous vehicles and other vehicles within range, ensuring low latency and reliable data exchange even in areas with limited cellular coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cellular networks are used for real-time monitoring of autonomous vehicles, then coverage and connectivity are provided, but latency and reliability are insufficient

Engineering Contradiction:

Improvereal-time monitoring reliabilityVSAvoidcommunication latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces V2V communication as an intermediary system that enables direct peer-to-peer communication between autonomous vehicles, bypassing the cellular network infrastructure. This mediator approach allows vehicles to exchange telemetry data directly, eliminating the latency and reliability constraints of cellular networks while maintaining coverage through decentralized communication.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If cellular networks are used for real-time monitoring, then connectivity is achieved, but coverage is limited in certain areas

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidcoverage area

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the centralized cellular network dependency into distributed V2V communication nodes. Each autonomous vehicle becomes an independent communication node that can directly connect with nearby vehicles, creating a mesh network topology. This segmentation eliminates the single-point failure mode of cellular networks and extends coverage to areas without cellular infrastructure.

Inventive Principle:

Principle #1Segmentation

3Productivity

If conventional monitoring systems are used, then infrastructure-based monitoring is provided, but real-time performance cannot be guaranteed

Engineering Contradiction:

Improvereal-time monitoring capabilityVSAvoidperformance guarantee

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements self-service monitoring where autonomous vehicles autonomously broadcast their own telemetry data (position, speed, acceleration, steering angle) to nearby vehicles without requiring external infrastructure. Each vehicle serves as its own monitoring station, eliminating the reliability issues associated with infrastructure-based systems and enabling guaranteed real-time performance through direct peer-to-peer communication.

Inventive Principle:

Principle #25Self-service
