Terminal-Specific Communication Quality Checks for Remote Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low communication quality can hinder remote driving operations, as it may not be possible to maintain effective communication between the operator and the vehicle, especially when the vehicle is in motion, and this quality varies based on the type of user terminal being used.
Innovation Solution
A communication system that includes a communication device capable of requesting and receiving communication quality information from specific types of user terminals, allowing for the determination and management of communication quality based on terminal type, thereby enabling informed decision-making about when to initiate or terminate remote driving operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If remote driving is performed without pre-acquiring communication quality, then remote driving operations can be initiated quickly, but communication quality may deteriorate during operation causing interruptions
Solution Approach 1:
The system performs preliminary acquisition of communication quality information before initiating remote driving operations. The communication quality management unit acquires communication quality data in advance, evaluates it against predetermined thresholds, and determines whether the communication environment is suitable for remote driving. This preliminary assessment ensures that remote driving is only initiated when communication quality meets required standards, preventing interruptions during operation.
2Reliability
If communication quality is monitored continuously for all user terminals, then communication quality can be maintained, but system complexity increases
Solution Approach 1:
The system applies different communication quality management approaches based on user terminal types. The determination unit identifies whether the user terminal is a first type (requiring strict communication quality control) or second type (with different requirements). For first type terminals, the system acquires communication quality information and compares it against thresholds to determine suitability for remote driving. For second type terminals, different evaluation criteria are applied. This differentiated approach maintains communication quality reliability while reducing unnecessary complexity for terminal types that don't require stringent monitoring.
3Ease of operation
If remote driving is performed without considering user terminal type, then operations can be simplified, but communication quality varies based on terminal capabilities
Solution Approach 1:
The system changes operational parameters based on user terminal type identification. When a first type user terminal is detected, the system applies strict communication quality thresholds and requires predetermined quality levels for remote driving. When a second type user terminal is detected, the system applies different evaluation criteria and thresholds. This parameter adjustment based on terminal type ensures that communication quality requirements match the actual capabilities and characteristics of each terminal type, maintaining both operational simplicity and communication quality consistency.

AI summary
A communication system includes a communication device that may transmit a command for requesting a response about communication quality to a specific type of user terminal, and a user terminal that may transmit the communication quality in response to the command.
