Driving Control Device Lane Change Intervention Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane change systems may improperly intervene by suppressing vehicle movement when a rear vehicle approaches, leading to driver discomfort due to varying right of way circumstances during lane changes.
Innovation Solution
A driving control device that includes side object detection, entry start determination, and activation suppression mechanisms to prevent unnecessary intervention by detecting the vehicle's entry into an adjacent lane and suppressing control activation when a side object is detected after entry has begun, especially in situations where the vehicle is likely to quickly finish changing lanes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control system activates suppression of sideways movement when a side object is detected, then collision avoidance with the side object is improved, but improper intervention occurs when the vehicle has already started entering the adjacent lane
Solution Approach 1:
The system determines whether the vehicle has started entering the adjacent lane before activating the suppression control. By checking the lateral position and movement state in advance, the system prevents improper intervention while maintaining collision avoidance capability. This preliminary determination ensures that suppression control is only activated when appropriate, avoiding unnecessary interference with ongoing lane changes.
2Reliability
If the system suppresses lane change whenever a rear vehicle is detected, then safety is improved, but the vehicle cannot complete timely lane changes when it has already started entering the adjacent lane
Solution Approach 1:
The system dynamically adjusts its response based on the vehicle's current state. When the vehicle has started entering the adjacent lane (determined by lateral position and movement), the system allows the lane change to complete even if a side object is detected. When the vehicle has not yet started entering, the system activates suppression control. This dynamic adjustment optimizes both safety and lane change efficiency.

AI summary
A driving control device according to the present invention activates a control for suppressing sideways movement of a vehicle towards a side object, when the side object present to the side of the vehicle as well as towards the rear of the vehicle is detected. Also, the activation of the control is suppressed when, in the absence of detection of the side object, the vehicle starts entering an adjacent lane in order to change lanes.
