Autonomous Driving Merge-Area Continuation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems face limitations in maintaining continuous autonomous travel control through merging and branching areas, requiring driver intervention due to the need for surroundings monitoring, which impairs convenience by reducing the duration of autonomous driving.
Innovation Solution
An autonomous driving control device equipped with a road shape grasping unit and a continuation determination unit allows the vehicle to assess and continue autonomous travel control based on the road shape of merging and branching areas, ensuring the driver's monitoring obligation is minimized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If autonomous driving control is maintained through merging and branching areas, then the duration of autonomous driving is extended, but the safety and reliability may be compromised due to complex road geometry requiring driver monitoring
Solution Approach 1:
The system changes the parameter of autonomous driving control based on road geometry detection. When a merging or branching area is detected, the control parameters are adjusted to determine whether to maintain or interrupt autonomous driving, thereby extending safe autonomous operation duration while ensuring reliability through conditional parameter modification
Solution Approach 2:
The road shape grasping unit and continuation determination unit act as intermediaries between the autonomous driving control system and the complex road environment. These components detect and analyze road geometry, serving as a mediator that enables safe extension of autonomous driving through merging and branching areas by providing intelligent decision-making capability
2Reliability
If driver monitoring obligation is required in merging and branching areas, then the safety is improved, but the convenience of autonomous driving is reduced
Solution Approach 1:
The system applies local quality by providing differentiated control strategies for different road sections. Instead of uniformly requiring driver monitoring in all merging and branching areas, the system locally adapts autonomous driving control based on specific road geometry characteristics, maintaining safety where applicable while preserving convenience where safe
Solution Approach 2:
The autonomous driving control is made dynamic by continuously detecting road shape and adjusting control status accordingly. The system dynamically transitions between autonomous and manual control modes based on real-time road geometry assessment, optimizing the balance between safety and convenience for each specific situation

AI summary
A road shape grasping unit is configured to grasp a road shape of a merging area present in a traveling direction of a subject vehicle traveling with an autonomous travel control in which a driver has no surroundings monitoring obligation. A continuation determination unit is configured to determine, according to the road shape of the merging area, whether to continue the autonomous travel control in the merging area.
