Lane-Change Control That Preserves Driving Assistance Level
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving control methods do not allow lane changes while maintaining a predetermined driving assistance level when a subject vehicle following a preceding vehicle encounters a lane without a preceding vehicle.
Innovation Solution
The driving control method and device detect the presence of another vehicle in the target lane before initiating lane-change control, ensuring the lane change is executed at the predetermined assistance level by maintaining travel behind the detected vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lane change is executed when no preceding vehicle is detected in the destination lane, then lane change control can be performed, but the driving assistance level cannot be maintained
Solution Approach 1:
The system performs preliminary detection of another vehicle in the destination lane before executing lane change control. By detecting the presence of another vehicle in advance, the system determines whether to maintain the current driving assistance level or switch to a lower level, thereby resolving the contradiction between enabling lane change and maintaining automation level.
2Ease of operation
If driving assistance level is maintained during lane change, then driver workload is reduced, but lane change may not be allowed when no preceding vehicle is detected
Solution Approach 1:
The system dynamically adjusts the driving assistance level based on the detection result of another vehicle in the destination lane. When another vehicle is detected, the system maintains the current driving assistance level; when not detected, it switches to a lower level. This dynamic adaptation allows the system to balance driver workload reduction with lane change permission across different traffic conditions.

AI summary
A driving control device controls driving of a subject vehicle at a predetermined driving assistance level using a processor under a condition of traveling behind a preceding vehicle. The processor determines whether another vehicle is detected in a second lane when the subject vehicle traveling in a first lane at the predetermined driving assistance level changes a lane to the second lane different from the first lane, keeps the traveling of the subject vehicle in the first lane until the other vehicle is detected when the other vehicle is not detected, and executes lane-change control at the predetermined driving assistance level after the other vehicle is detected.
