Vehicle Control Device Cut-in Evasive Preparation
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 from an adjacent lane, often resulting in delayed responses due to low detection accuracy of lateral position changes, which can lead to insufficient margins and discomfort for passengers.
Innovation Solution
A vehicle control device that includes an object recognition unit, a monitoring target vehicle detection unit, an evasive preparation execution unit, and an evasive action execution unit, which senses characteristic motions and relative motions to execute evasive preparations and actions in two stages, avoiding interference without early or abrupt evasive actions.

Engineering Contradiction Analysis
1Reliability
If evasive action is started based on lateral position change detection, then the system can respond to cut-in vehicles, but the detection accuracy is low causing delayed response and insufficient margin
Solution Approach 1:
The system performs preliminary action by detecting characteristic motions (acceleration, deceleration, lane position changes) that precede a cut-in maneuver. When such motions are detected, the system executes evasive preparation in advance, positioning the own-vehicle to be ready for potential cut-in scenarios before the actual lateral movement occurs, thereby reducing response time delay while maintaining reliable detection.
2Reliability
If evasive action is executed early to ensure safety margin, then interference with cut-in vehicle is avoided, but passenger discomfort increases due to abrupt or premature action
Solution Approach 1:
The system executes evasive preparation in advance when characteristic motions are detected, but delays the actual evasive action until the monitoring target vehicle enters the own-lane or is about to do so. This two-stage approach ensures safety margin is maintained while avoiding abrupt or premature actions that would cause passenger discomfort.
Solution Approach 2:
The system dynamically adjusts the timing and intensity of evasive actions based on real-time detection of the monitoring target vehicle's motion state and position. The evasive preparation phase allows gradual adjustment, while the execution phase is triggered only when necessary conditions are met, optimizing both safety and passenger comfort.

AI summary
A vehicle control device according to an example in the present disclosure detects a monitoring target vehicle that may potentially cut into an own-lane from an adjacent lane. Further, the vehicle control device first executes an evasive preparation when sensing a predetermined relative motion of the monitoring target vehicle relative to the flow of the adjacent lane. The vehicle control device executes an evasive action to avoid interference between the monitoring target vehicle and the own-vehicle.
