Solution Overview

Problem

Current computer-assisted and autonomous driving (CA/AD) vehicles are unable to effectively detect and correct human errors made by vulnerable road users (VRUs), despite being equipped with advanced sensing technologies and computing systems.

Innovation Solution

The implementation of a Vehicle-to-Everything (V2X) communication system, specifically designed for Intelligent Transport Systems (ITS), which enables CA/AD vehicles to communicate directly with other vehicles, infrastructure, and VRUs, thereby enhancing awareness and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If CA/AD vehicles are equipped with advanced sensing technologies and computing systems, then the vehicle's sensing and computing capabilities are improved, but the ability to detect and correct human errors at VRUs' end remains insufficient

Engineering Contradiction:

Improvedetection capabilityVSAvoiderror correction capability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent introduces V2X communication technology as an intermediary between CA/AD vehicles and VRUs. This communication system enables direct information exchange, allowing vehicles to receive alerts and status information from VRUs' devices, thereby compensating for the limitation of sensing systems in detecting human errors at the VRU end.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements a feedback mechanism where VRUs' devices can send alerts, warnings, and status information to CA/AD vehicles in real-time. This feedback loop enables the vehicle system to be aware of VRU states and human errors, allowing for timely responses and corrections that sensing systems alone cannot achieve.

Inventive Principle:

Principle #23Feedback

2Reliability

If V2X communication system is implemented, then traffic safety and efficiency are improved, but the system complexity increases

Engineering Contradiction:

Improvetraffic safetyVSAvoidcommunication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs the V2X communication system to serve multiple functions simultaneously: safety alerting, status information exchange, collision warning, and coordination between vehicles and VRUs. This multi-functionality reduces the need for separate specialized systems, thereby managing complexity while achieving comprehensive safety improvements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the V2X communication system into distinct functional modules including alert generation, message transmission, reception processing, and response execution. This modular segmentation allows each component to be optimized independently and simplifies the overall system architecture, making the complex communication system more manageable and maintainable.

Inventive Principle:

Principle #1Segmentation
