Remote Vehicle Operation Authority Based on Communication Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Despite efforts to reduce communication latency between remote operation devices and vehicles, communication quality can still deteriorate due to system convergence, leading to unintended vehicle behavior.
Innovation Solution
A remote operation device that acquires communication quality and sets operational authority based on this quality, restricting or allowing manual operations to ensure safe vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If communication amount is reduced by transmitting difference information of three-dimensional map data, then communication efficiency is improved, but communication quality may deteriorate due to other causes such as system convergence
Solution Approach 1:
The system dynamically adjusts the operator's authority level based on real-time communication quality assessment. When communication quality is high, full manual operation authority is granted. When communication quality deteriorates (regardless of data amount), the system automatically reduces authority to prevent unintended vehicle behavior, thus resolving the contradiction between reducing communication amount and maintaining communication quality.
2Ease of operation
If manual operation authority is allowed without restriction, then ease of operation is improved, but safety deteriorates due to unintended vehicle behavior from poor communication quality
Solution Approach 1:
The system changes the parameter of operator authority level based on communication quality assessment. The authority parameter is adjusted between different states (full authority, restricted authority, emergency takeover) depending on the assessed communication quality, thereby balancing ease of operation with operation safety.
Solution Approach 2:
The system continuously monitors communication quality and provides feedback to adjust the operator's authority level. This closed-loop feedback mechanism ensures that when communication quality deteriorates, the system automatically restricts manual operations to prevent unsafe behavior, while allowing full operation freedom when communication quality is good.
3Reliability
If authority restriction is applied to prevent unintended behavior, then safety is improved, but ease of operation deteriorates due to limited manual control
Solution Approach 1:
The system makes the authority restriction dynamic rather than static. Authority is restricted only when communication quality assessment indicates potential safety risks, and full control is restored when communication quality improves. This dynamic adjustment prevents unnecessary restriction of manual control freedom while maintaining operation safety when needed.
