Automated Lane Change Control Based on Driver Preparation Level
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving systems are unable to appropriately perform lane changes, as they do not effectively assess the driver's preparation level to approve or deny lane changes based on their attention and readiness.
Innovation Solution
A moving body control apparatus that includes a judging section to assess the driving preparation level of an occupant and a lane change control section to approve first and second lane changes based on predefined levels, allowing for appropriate lane changes according to the occupant's level of readiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated driving systems perform lane changes without assessing driver preparation level, then lane change operation is simplified and faster, but safety and appropriateness of lane change is compromised
Solution Approach 1:
The system performs preliminary assessment of the driver's preparation level before executing a lane change. The judging section evaluates whether the driver is ready for automation takeover, and only approves lane changes when the driver meets the required preparation threshold, ensuring safety before the maneuver occurs
Solution Approach 2:
The system continuously monitors driver state and provides feedback by adjusting lane change approval based on real-time assessment of driver preparation level. The lane change control section receives input from the judging section about driver readiness and dynamically controls whether lane changes are permitted, creating a closed-loop safety mechanism
2Reliability
If the system requires high driver preparation level for lane changes, then safety is improved, but lane change frequency and efficiency decrease
Solution Approach 1:
The system dynamically adjusts the lane change approval criteria based on the assessed driver preparation level. When the driver demonstrates adequate readiness, lane changes are approved; when readiness is insufficient, lane changes are denied. This dynamic adaptation allows the system to maximize lane change frequency while maintaining safety thresholds
3Reliability
If the system adds driver preparation level assessment before lane changes, then lane change appropriateness is improved, but system complexity increases
Solution Approach 1:
The control system is segmented into distinct functional sections: a judging section that assesses driver preparation level and a lane change control section that makes approval decisions. This segmentation modularizes the complexity, making the system more manageable and maintainable while achieving improved lane change appropriateness

AI summary
A moving body control apparatus includes a judging section that judges a driving preparation level of an occupant of a moving body; and a lane change control section that approves a first lane change, which is a lane change in which a lane boundary line is crossed once, if the driving preparation level of the occupant is greater than or equal to a first level, and approves a second lane change, which is a lane change in which lane boundary lines are crossed a plurality of times, if the driving preparation level of the occupant is greater than or equal to a second level that is higher than the first level.
