Solution Overview

Problem

Autonomous vehicles face challenges in determining when to switch to remote control mode due to errors in autonomous driving functions or driver conditions, leading to potential safety issues and inefficiencies in communication with nearby vehicles or infrastructure.

Innovation Solution

A server-based control method that acquires and analyzes vehicle information to determine if remote control is needed, allowing for remote control by the server or nearby objects, including determining communication quality and emergency situations, to ensure safe operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If autonomous driving functions are used, then user convenience and automation are improved, but errors in autonomous driving functions may occur leading to safety issues

Engineering Contradiction:
Improveautonomous driving functionVSAvoidsafety
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

A server is introduced as an intermediary between the autonomous vehicle and the remote controller. The server receives information from the autonomous vehicle, determines whether remote control is needed, and facilitates communication with nearby vehicles or infrastructure. This intermediary system enables timely intervention when autonomous driving errors occur, resolving the contradiction between automation and safety.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements a feedback mechanism where the server continuously monitors information from the autonomous vehicle, compares it with stored information, and determines when remote control intervention is necessary. This feedback loop ensures that safety issues can be detected and addressed promptly, maintaining reliability while allowing autonomous operation.

Inventive Principle:
Principle #23Feedback

2Reliability

If remote control is implemented for error correction, then safety is improved, but communication complexity with nearby vehicles or infrastructure increases

Engineering Contradiction:
ImprovesafetyVSAvoidcommunication system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The server is designed with multi-functionality, serving as an information receiver, analyzer, decision-maker, and communication facilitator. By consolidating these functions in a single universal system, the patent reduces overall communication complexity while maintaining safety through coordinated remote control capabilities.

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

3Reliability

If the server continuously monitors vehicle information, then safety and error detection are improved, but information processing load and communication overhead increase

Engineering Contradiction:
Improveerror detectionVSAvoidcommunication overhead
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The server performs partial monitoring by selectively determining whether remote control is needed rather than continuously analyzing all vehicle information. The system compares acquired information with stored information only when necessary, reducing communication overhead and energy consumption while maintaining effective error detection capabilities.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A control method for an autonomous vehicle and a server implementing the control method, the method including: acquiring, by a server, information related to the vehicle; determining, by the server, based on the acquired information, whether the vehicle needs to be remotely controlled; and based on the determination that the vehicle needs to be remotely controlled, remotely controlling the autonomous vehicle by the server or a nearby object.
