Automated Driving Offset Control for Driver Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous driving systems, offset control can cause discomfort for drivers who do not monitor the periphery, leading to troublesome acceleration, especially during periods without periphery monitoring obligations.
Innovation Solution
An automated driving control device that switches between driving assistance with periphery monitoring and autonomous travel without monitoring, limiting offset control execution during autonomous driving periods and adjusting offset control based on lane position, traffic congestion, and driver status to reduce lateral acceleration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If offset control is executed during autonomous driving without periphery monitoring obligation, then safety distance from other vehicles is increased, but driver comfort deteriorates due to troublesome lateral acceleration
Solution Approach 1:
The system dynamically adjusts the execution of offset control based on the autonomous driving level. At Level 3 (with periphery monitoring obligation), offset control is executed to maintain safety distance. At Level 4 (without periphery monitoring obligation), offset control is limited or not executed to prevent troublesome lateral acceleration and improve driver comfort. This dynamic switching resolves the contradiction by adapting the control strategy to the specific operational context.
2Reliability
If offset control is continuously executed to maintain safety distance, then collision risk is reduced, but frequency of lateral acceleration increases causing driver annoyance
Solution Approach 1:
The system applies different control qualities to different driving scenarios. When the driver has periphery monitoring obligation (Level 3), offset control is actively executed to maintain safety distance and reduce collision risk. When the driver does not have monitoring obligation (Level 4), the control quality changes to limit offset execution, thereby reducing lateral acceleration frequency and driver annoyance. This localized adaptation of control quality resolves the contradiction between safety and comfort.
