Lane Change Warning Control Using After-Next Lane Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems lack an accurate method for controlling warnings during lane changes, particularly in determining the possibility of changing lanes to an after-next lane or a vehicle on the after-next lane entering the next lane.
Innovation Solution
A vehicle control device and method that includes a controller capable of determining, during a next lane change activation period, the possibility of a host vehicle changing lanes to an after-next lane or a vehicle on the after-next lane entering the next lane based on vehicle information, and controlling a warning device to issue warnings accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle system issues warnings during lane changes, then driving safety is improved, but false or unnecessary warnings increase
Solution Approach 1:
The system dynamically changes the warning determination parameters by considering multiple factors including vehicle speed, lane change activation period, and after-next lane vehicle presence. The controller adjusts the warning issuance criteria based on these parameter changes to distinguish between necessary and unnecessary warnings
Solution Approach 2:
The controller acts as an intermediary that mediates between the lane change detection system and the warning device. It introduces additional determination steps involving after-next lane vehicle information as an intermediary factor before triggering the warning, thereby filtering out false warnings
2Measurement precision
If the system determines possibility of lane change to after-next lane, then warning accuracy is improved, but system complexity increases
Solution Approach 1:
The warning determination process is segmented into distinct stages: first determining if a vehicle is present in the after-next lane, then separately evaluating the possibility of lane change to after-next lane or after-next lane vehicle entering next lane. This segmentation improves accuracy while managing complexity through structured decision-making
Solution Approach 2:
The system performs preliminary determination of after-next lane vehicle presence and lane change possibility before issuing the final warning. This preliminary action allows the system to pre-assess risk factors and only proceed with warnings when necessary conditions are met

AI summary
Provided are a vehicle control device and method, and a vehicle system. The vehicle control device include a controller operative to control a host vehicle. The controller is operative to determine, during a next lane change activation period during which the host vehicle is able to change lanes from a travel lane to a next lane, at least one of a possibility of the host vehicle changing lanes to an after-next lane or a possibility of an after-next lane vehicle entering the next lane based on vehicle information, and control a warning to be issued to the host vehicle based on the determination results.
