Solution Overview
Problem
Existing vehicle control technologies lack precision in navigating lane changes based on surrounding situations, leading to suboptimal control decisions.
Innovation Solution
A vehicle control device and method that recognizes surrounding situations by identifying specific first and second vehicles based on inter-vehicle distances and predicts future positions to strategically move the vehicle to their vicinity, optimizing lane changes by considering vehicle speeds and intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing vehicle control technology is used for lane changing, then the control can be implemented, but the precision of control in accordance with surrounding situation is insufficient
Solution Approach 1:
The patent segments the surrounding vehicles into three distinct groups based on their spatial relationship to the lane change target: first vehicles (in front of the target region), second vehicles (behind the target region), and third vehicles (other surrounding vehicles). This segmentation allows the control system to apply different control priorities and strategies to each group, thereby achieving precise control adapted to the specific surrounding situation.
Solution Approach 2:
The patent applies different control strategies to different spatial zones around the vehicle. Specifically, the system identifies a target region for lane changing and differentiates between vehicles in front of this region (first vehicles), vehicles behind the region (second vehicles), and other vehicles (third vehicles). Each group receives tailored control treatment based on its local spatial context, enabling adaptive precision control.
2Manufacturing precision
If the vehicle changes lane without considering specific vehicle positions, then the lane change can be performed, but the precision and smoothness of the maneuver is reduced
Solution Approach 1:
The patent performs preliminary identification and classification of surrounding vehicles into first, second, and third vehicles before executing the lane change maneuver. The system calculates appropriate speed ranges and determines target speeds in advance based on the positions of these classified vehicles. This preliminary action ensures that the lane change is executed with high precision while maintaining manageable control complexity through structured pre-planning.
3Measurement precision
If the vehicle does not predict future positions of surrounding vehicles, then the control calculation is simpler, but the accuracy of lane change timing and positioning is reduced
Solution Approach 1:
The patent incorporates feedback mechanisms where the system continuously monitors the positions and movements of surrounding vehicles (first, second, and third vehicles) and uses this information to calculate appropriate speed ranges and adjust target speeds. This feedback loop enables accurate prediction of future positions and optimal lane change timing while managing calculation efficiency through structured processing of vehicle group data.

AI summary
A vehicle control device includes: a recognizer configured to recognize a surrounding situation of a vehicle; and an action controller configured to control an action of the vehicle. The action controller is configured to specify a first vehicle in front of a region which the vehicle is scheduled to enter and a second vehicle behind the region according to inter-vehicle distances between a plurality of vehicles located in front of or on the side of the vehicle in a lane of a route changing destination recognized by the recognizer when a route of the vehicle is changed to a side. The action controller is configured to cause the vehicle to move to a vicinity of the specified first and second vehicles in a lane in which the vehicle is traveling.
