Autonomous Vehicle Relay for Remote Driving Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated vehicle and highway systems face challenges in remote driving, particularly when communication between vehicles and terminals is impaired, leading to difficulties in sensor data validity and communication quality, which hinders effective remote control and navigation.
Innovation Solution
A remote driving method is implemented using another autonomous vehicle, where positional information and sensor data are transmitted to establish communication, allowing the second vehicle to move and trace the first vehicle, and to transmit control messages based on sensor data, ensuring continuous operation even in areas with poor communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct communication between terminal and first device is used for remote driving, then communication quality is maintained, but communication reliability deteriorates when communication is impossible
Solution Approach 1:
The patent introduces a second device (autonomous vehicle) as an intermediary to relay communication between the terminal and first device. When direct communication fails, the terminal communicates with the second device, which then communicates with the first device, ensuring communication reliability without requiring complex alternative communication systems.
Solution Approach 2:
The second device serves multiple functions: it acts as a relay for communication, provides sensor data support, and can perform remote driving operations. This multi-functionality reduces the need for separate specialized systems, maintaining reliability without proportionally increasing complexity.
2Measurement precision
If sensor data from first device is used for remote driving, then control accuracy is improved, but system reliability deteriorates when sensor data is not valid
Solution Approach 1:
The second device acts as an intermediary sensor source when the first device's sensors are invalid. The terminal can request sensor data from the second device, which provides alternative sensor information to maintain control accuracy and system reliability when primary sensors fail.
Solution Approach 2:
The system prepares alternative sensor data sources in advance. When the first device's sensor data becomes invalid, the second device's sensor data is already available as a pre-prepared backup, ensuring continuous reliable operation without interruption.
3Ease of operation
If second device traces first device using positional information, then remote driving capability is improved, but communication requirements increase in poor communication areas
Solution Approach 1:
The second device autonomously traces the first device using positional information without requiring continuous real-time communication. The device independently navigates to and follows the target vehicle, reducing communication frequency and improving reliability in poor communication areas while maintaining remote driving capability.

AI summary
A remote driving method using another autonomous device of a network in automated vehicle & highway systems can including transmitting, to a second device, a remote driving request message, when a message indicating impossibility of communication between a first device and a terminal connected to the network is received from the terminal, receiving, from the second device, a success response message for establishment of communication for remote driving of the first device, and transmitting, to the first device, a remote driving start message. One or more of an autonomous vehicle, a user terminal and a server of the present invention can be associated with artificial intelligence modules, drones (unmanned aerial vehicles (UAVs)), robots, augmented reality (AR) devices, virtual reality (VR) devices, devices related to 5G service, etc.
