Solution Overview

Problem

Autonomous vehicles face challenges in maintaining control during failures or adverse weather conditions, leading to difficulties in remote driving and potential safety accidents when drivers are incapacitated or sensors malfunction.

Innovation Solution

A vehicle control system that includes a communication device for connecting with a remote control center and a controller to determine the state of vehicle components, switching between remote driving mode, emergency action mode, and autonomous driving maintenance mode based on component states, allowing for remote control and emergency interventions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If autonomous driving is implemented, then convenience for passengers and drivers is improved, but reliability deteriorates when sensors fail or cannot recognize surroundings due to heavy rain or snow

Engineering Contradiction:

Improveconvenience for passengers and driversVSAvoidreliability when sensors fail or cannot recognize surroundings

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A remote control center is introduced as an intermediary between the autonomous vehicle and the final control decisions. When the autonomous driving controller cannot reliably control the vehicle due to sensor failures or adverse weather, the remote control center receives vehicle status information and provides remote control commands, ensuring continuous reliable operation without requiring manual intervention from passengers or drivers

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary assessment of component device states and autonomously determines whether to switch to remote driving mode before complete failure occurs. The controller continuously monitors sensor and component status, and proactively transfers control to the remote control center when reliability thresholds are not met, preventing safety accidents before they happen

Inventive Principle:

Principle #10Preliminary action

2Reliability

If manual driving is used when autonomous driving fails, then reliability is improved, but ease of operation deteriorates when driver's health deteriorates or in unmanned autonomous vehicles

Engineering Contradiction:

Improvereliability when autonomous driving failsVSAvoidease of operation when driver's health deteriorates or in unmanned vehicles

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The remote control center serves as a remote intermediary operator that can assist the vehicle when the local driver is incapacitated or when no driver is present. The remote control center receives vehicle status and provides control commands, ensuring continuous reliable operation without requiring physical presence or manual intervention from the driver

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The autonomous vehicle system includes self-service capabilities through the remote control center that can autonomously assist the vehicle without external human intervention. The system automatically detects when driver assistance is needed and activates remote control, allowing the vehicle to service itself through remote assistance rather than requiring immediate manual takeover

Inventive Principle:

Principle #25Self-service

3Reliability

If remote driving is implemented when autonomous driving is impossible, then reliability is improved, but loss of time increases due to communication delay

Engineering Contradiction:

Improvereliability when autonomous driving is impossibleVSAvoidloss of time due to communication delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary assessment of component device states and autonomously determines whether to switch to remote driving mode before complete failure occurs. This proactive approach reduces the time needed to respond to failures by having the system already prepared to switch modes, minimizing communication delays

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The remote control center maintains continuous communication with the autonomous vehicle, receiving real-time vehicle status information and providing continuous control commands. This continuous action ensures that control is seamlessly transferred and maintained without interruption, minimizing the impact of communication delays on overall system reliability

Inventive Principle:

Principle #20Continuity of useful action
