Vehicle Control Device for Cut-In Interference Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems are inadequate in determining evasive actions when another vehicle cuts into the own-lane at locations other than merging places, leading to potential interference and discomfort due to abrupt evasive maneuvers.
Innovation Solution
A vehicle control device with an object recognition unit, road shape information acquisition unit, monitoring target vehicle detection unit, evasive preparation execution unit, and evasive action execution unit, which recognizes potential cut-in scenarios from road shapes and executes evasive preparations and actions to avoid interference without causing discomfort to passengers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If evasive action is started early based on lateral position change of another vehicle, then interference with cutting-in vehicle is avoided, but passenger discomfort increases due to abrupt evasive maneuvers
Solution Approach 1:
The system performs preliminary action by detecting road shapes that prompt cut-in (merging lanes, bifurcating lanes, junctions) and identifying monitoring target vehicles in advance. Evasive preparation is executed before the actual cut-in occurs, allowing the own-vehicle to be positioned to avoid interference while preventing abrupt maneuvers. The evasive action is only executed when the monitoring target vehicle actually begins its cut-in motion, not merely based on lateral position changes.
Solution Approach 2:
The system dynamically adjusts the evasive strategy based on real-time conditions. It transitions from a static lateral-position-based approach to a dynamic road-shape-aware approach that considers the specific geometry of the road ahead. The monitoring target vehicle detection unit dynamically identifies vehicles likely to cut-in based on road context, and the evasive preparation execution unit adjusts preparations based on the detected road shape and vehicle motion patterns.
2Speed
If conventional lateral position-based evasive action is used, then response to cut-in is achieved, but it fails to account for road shapes other than merging places
Solution Approach 1:
The system achieves universality by extending the cut-in detection capability to multiple road shape types. The road shape information acquisition unit identifies not only merging places but also bifurcating lanes, junctions, and other road configurations that may prompt cut-in. The monitoring target vehicle detection unit applies the same detection logic across all these road shapes, making the system versatile while maintaining fast response through the unified early detection mechanism.
3Object-affected harmful factors
If evasive action is delayed until cut-in is certain, then passenger comfort is maintained, but interference with cutting-in vehicle occurs
Solution Approach 1:
The system executes evasive preparation in advance when a monitoring target vehicle is detected in a road shape that prompts cut-in, but before the actual cut-in motion begins. This preliminary positioning allows the own-vehicle to be ready to avoid interference while not yet executing abrupt maneuvers that would cause passenger discomfort. The actual evasive action is then executed smoothly when the cut-in motion is detected, maintaining comfort while ensuring avoidance.

AI summary
The vehicle control device recognizes an object around an own-vehicle and acquires information related to a road shape ahead of the own-vehicle. The vehicle control device detects, when a road shape prompting cut-in to an own-lane is acquired, a monitoring target vehicle likely to be prompted to cut into the own-lane among the recognized objects. The vehicle control device executes an evasive preparation for cut-in of the monitoring target vehicle when the monitoring target vehicle is detected. The vehicle control device executes an evasive action to avoid interference between the monitoring target vehicle and the own-vehicle when a predetermined motion from which cut-in of the monitoring target vehicle to the own-lane is expected is sensed after the evasive preparation is executed.
