Lane Change Control Timing for Consistent Autonomous Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems fail to appropriately adjust setting information during lane changes, potentially leading to improper settings and occupant discomfort due to inconsistent vehicle behavior.
Innovation Solution
A moving body control device and method that dynamically adjust the reference time for canceling a lane change based on setting information, such as lateral velocity and export destination, to ensure consistent and comfortable lane change operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lane change control is stopped when a predetermined event continues during a first time, then the safety is improved, but the lane change efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the first time period variable rather than fixed. The control stopping duration is dynamically adjusted based on whether the vehicle is in the process of changing lanes when the predetermined event occurs. If lane change is in progress, the first time is set to a shorter second time period; if not, the normal first time applies. This dynamic adjustment resolves the contradiction by adapting the safety monitoring duration to the actual operational context.
Solution Approach 2:
The patent changes the parameter of time duration based on the vehicle's operational state. When the vehicle is executing a lane change maneuver and the predetermined event occurs, the system switches from using the standard first time period to using a shorter second time period. This parameter change allows the system to maintain safety monitoring while reducing unnecessary control interruption duration, thereby improving lane change efficiency without compromising safety.
2Speed
If the first time is set to be shorter as the second time becomes shorter, then the responsiveness is improved, but the control stability deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the control stopping duration based on the specific operational context. Instead of using a uniform time period for all situations, the system applies a shorter second time period specifically when the vehicle is in the process of changing lanes, while using the standard first time period for other situations. This localized adjustment ensures responsiveness during critical lane change maneuvers while maintaining control stability during normal operations.

AI summary
A moving body control device includes a lane change controller configured to change a lane of a moving body from a first lane in which the moving body is located to a second lane adjacent to the first lane regardless of an operation of an occupant, the lane change controller configured to stop control related to the lane change when a predetermined event continues during a first time, and a setting change part configured to change setting of the first time on the basis of setting information of the lane change.
