Solution Overview

Problem

Autonomous vehicles face difficulties navigating around obstacles, particularly when lane markings interfere with their path, necessitating an expert mode for manual intervention to facilitate safe movement.

Innovation Solution

A system and method that allow manual instructions from a remote user to be implemented via a processor onboard the autonomous vehicle, utilizing a remote computer module and an autonomous vehicle computer module to determine assistance needs and facilitate movement around obstacles by generating alternate paths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the autonomous vehicle relies solely on automatic navigation systems, then the extent of automation is high, but the ability to navigate around obstacles is insufficient when lane markings interfere with the path

Engineering Contradiction:
Improveability to navigate around obstaclesVSAvoidlevel of manual intervention
Core Design Contradiction:
Adaptability or versatilityVSExtent of automation

Solution Approach 1:

The system dynamically switches between fully autonomous mode and expert mode with remote human assistance based on the complexity of the navigation situation. When obstacles require maneuvers that conflict with lane markings or require human judgment, the system transitions to expert mode, allowing dynamic adaptation of the automation level to match the situational demands

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A remote user acts as an intermediary between the autonomous vehicle's automatic navigation system and the environment. When the autonomous system encounters obstacles it cannot handle, the remote user provides manual instructions that bridge the gap between automated operation and human decision-making capability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the autonomous vehicle implements manual instructions from remote users, then the ease of operation improves for complex scenarios, but the device complexity increases due to additional communication and control systems

Engineering Contradiction:
Improveability to handle complex navigation scenariosVSAvoidcommunication and control system architecture
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The complex decision-making capability is extracted from the vehicle itself and placed in a remote location. Instead of embedding sophisticated obstacle negotiation algorithms in the vehicle's onboard computer, the system extracts this function to human operators who can be accessed on-demand, reducing the computational complexity requirements of the vehicle's own systems

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The remote user system serves multiple functions: it provides obstacle negotiation assistance, handles edge cases beyond the autonomous system's training, and can intervene in any situation where the vehicle requests help. This multi-functionality justifies the added communication infrastructure by consolidating various complex operations through a single remote assistance channel

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