Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in continuing smooth operation when encountering situations such as vehicle failures, accidents, or areas where autonomous driving is not possible, leading to difficulties in following the driving path, and existing systems lack effective methods for determining when remote control is required.
Innovation Solution
An autonomous driving control apparatus with a processor that determines the need for remote control based on factors like vehicle failures, accidents, positioning data reliability, stopping time, and hand signal responses, and communicates with a control system to switch from autonomous driving to remote control mode, using V2X communication and in-vehicle sensing data.

Engineering Contradiction Analysis
1Extent of automation
If autonomous driving control is implemented without remote control capability, then automation level is improved, but reliability deteriorates when failures or accidents occur
Solution Approach 1:
A remote control server acts as an intermediary between the autonomous vehicle and human operators. The server receives vehicle status information, determines whether remote control is needed based on predetermined conditions (failures, accidents, positioning reliability issues, prolonged stopping), and establishes communication channels for remote intervention when necessary, thus maintaining high automation while providing a safety net.
Solution Approach 2:
The system performs preliminary assessment of remote control necessity by continuously monitoring vehicle status, failure states, accident detection, positioning reliability, and stopping patterns. This preliminary determination is made before actual remote control intervention is needed, allowing the system to prepare and switch modes proactively rather than reactively.
2Reliability
If remote control request mechanisms are added to autonomous vehicles, then reliability is improved, but device complexity increases
Solution Approach 1:
The complex remote control decision-making logic and communication management functions are extracted from the vehicle's onboard systems and relocated to a separate remote control server. This extraction allows the vehicle to maintain simpler autonomous driving control while the server handles the complexity of determining when remote intervention is needed and managing the remote control connection.
Solution Approach 2:
The remote control server is designed as a universal platform that can serve multiple autonomous vehicles simultaneously. It handles various types of remote control requests (failures, accidents, positioning issues, stopping anomalies) and provides a unified interface for remote operators, thereby distributing the complexity burden across a multi-functional system rather than adding dedicated complexity to each vehicle.
3Reliability
If continuous monitoring of vehicle status is performed to determine remote control need, then reliability is improved, but energy consumption increases
Solution Approach 1:
The system implements partial monitoring by focusing only on specific critical parameters that indicate remote control necessity (failure states, accident detection signals, positioning reliability metrics, abnormal stopping patterns) rather than continuously monitoring all vehicle systems. This selective monitoring approach maintains reliability for safety-critical functions while minimizing unnecessary energy consumption.
