Remote Driving Communication Throughput Margin Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote driving technologies face challenges in maintaining throughput during remote driving, particularly due to communication delays and decreased throughput, which can hinder the accuracy and speed of remote operations.
Innovation Solution
A communication method that detects or estimates decreases in throughput for a first communication terminal on a remotely driven vehicle and reduces the communication speed of a second communication terminal sharing the same communication resource, thereby alleviating the decrease in throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication resources are shared between multiple vehicles, then resource utilization efficiency is improved, but throughput of remote driving vehicles deteriorates
Solution Approach 1:
The patent applies local quality by providing differentiated communication resource allocation based on vehicle type and service requirement. Remote driving vehicles receive prioritized resource allocation with guaranteed throughput, while other vehicles receive remaining resources. This creates different quality levels of service within the same communication system, ensuring that critical remote driving operations maintain reliable throughput even when resources are shared.
Solution Approach 2:
The patent changes the parameter of communication resource allocation from equal distribution to dynamic allocation based on service priority. The system monitors throughput requirements and adjusts resource allocation parameters in real-time, ensuring that remote driving vehicles receive sufficient resources to maintain minimum throughput thresholds while allowing other vehicles to utilize remaining capacity.
2Reliability
If communication speed of second vehicle is reduced to generate margin, then throughput of first vehicle is improved, but communication efficiency of second vehicle deteriorates
Solution Approach 1:
The patent applies local quality by creating different communication quality levels for different vehicles. The first vehicle (remote driving) receives guaranteed high-quality service with prioritized resource allocation, while the second vehicle receives lower-priority allocation. This localized differentiation ensures that the first vehicle's throughput requirements are met without completely starving the second vehicle of communication resources.
Solution Approach 2:
The patent introduces a communication control device as an intermediary that mediates resource allocation between vehicles. This intermediary monitors communication conditions, detects throughput decreases, and dynamically adjusts resource allocation to generate necessary margins for remote driving operations while maintaining reasonable communication efficiency for other vehicles.

AI summary
A communication method of the present disclosure includes detecting or estimating a decrease in throughput of a first communication terminal mounted on a first vehicle that is remotely driven, and reducing a communication speed of a second communication terminal with which the first communication terminal shares a communication resource in response to detection or estimation of the decrease in the throughput.
