Auto Lane Change Control With Direction-Based Confirmation Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In auto lane change technology, the surrounding confirmation time for the driver to verify the vehicle's surroundings may not be sufficient in certain directions, leading to a decrease in the execution opportunity of lane changes.
Innovation Solution
A control device that adjusts the surrounding confirmation time based on the direction of the lane change, ensuring sufficient time for the driver to confirm the surroundings by varying the notification and execution timing accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surrounding confirmation time is uniformly lengthened to ensure sufficient confirmation in all directions, then the driver can sufficiently confirm the surroundings of the vehicle, but the execution opportunity of the lane change decreases
Solution Approach 1:
The patent applies local quality by setting different surrounding confirmation times based on the specific lane change direction. When the lane change is to the left, a first surrounding confirmation time is used, and when the lane change is to the right, a second surrounding confirmation time is used. This allows each direction to have optimized confirmation time tailored to its specific requirements, rather than applying a uniform time to all directions.
Solution Approach 2:
The patent implements dynamics by making the surrounding confirmation time variable depending on the lane change direction. The system dynamically adjusts the confirmation time based on the detected direction (left or right), allowing the confirmation period to adapt to the specific operational context rather than remaining fixed or uniformly extended.
2Reliability
If the surrounding confirmation time is set to ensure safety in all directions, then the driver can confirm the surroundings sufficiently, but the time required for lane change execution increases
Solution Approach 1:
The patent applies local quality by setting different surrounding confirmation times based on the specific lane change direction. When the lane change is to the left, a first surrounding confirmation time is used, and when the lane change is to the right, a second surrounding confirmation time is used. This allows each direction to have optimized confirmation time tailored to its specific requirements, rather than applying a uniform time to all directions.
Solution Approach 2:
The patent changes the time parameter of the surrounding confirmation period based on the lane change direction. By adjusting the confirmation time parameter according to whether the lane change is left or right, the system optimizes the balance between safety confirmation and execution efficiency for each specific scenario.

AI summary
A control device includes: a recognition unit configured to recognize at a surrounding situation of a moving object; a lane change determination unit configured to determine, based on the surrounding situation, whether lane change control is executable; a travel control unit configured to execute the lane change control in response to determination that the lane change control is executable; and a notification control unit configured to issue predetermined notification to an occupant of the moving object. The notification control unit issues, to the occupant of the moving object, notification that the lane change control is to be started in response to the determination. The travel control unit starts the lane change control after a predetermined time elapses from when the notification is started. The predetermined time differs depending on a lane change direction of the moving object under the lane change control.
