Cut-in Intention Determination Using Environmental Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles lack accurate methods to determine a surrounding vehicle's intention to cut in, often leading to unnecessary deceleration and discomfort for drivers, as they rely solely on physical values and limited environmental information, especially in specific road sections like merging or diverging lanes.
Innovation Solution
An apparatus and method that utilize a navigation module, camera, radar, and sensor to gather data on road environments, traffic, and curvature, adjusting parameters to assess the likelihood of a surrounding vehicle cutting in, considering factors like road sections, lane numbers, average speeds, and curvature, to provide more accurate intentions to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional vehicles use only physical values (lateral location, speed, acceleration) to determine cut-in intention, then the determination method is simple, but the accuracy of determining cut-in intention is low
Solution Approach 1:
The patent changes the parameters used for determination from only physical values (lateral location, speed, acceleration) to include environmental context parameters (road type, merging/diverging sections, lane information). This allows the system to accurately determine cut-in intention by considering whether the surrounding vehicle is in a merging or diverging section, resolving the contradiction between simple determination method and low accuracy.
2Reliability
If conventional vehicles increase distance from preceding vehicle in merging or diverging sections, then collision avoidance capability is improved, but unnecessary deceleration occurs when surrounding vehicle does not have cut-in intention
Solution Approach 1:
The patent applies preliminary action by proactively increasing distance from the preceding vehicle when the system detects that the surrounding vehicle is in a merging or diverging section. This preliminary distance increase is based on environmental context recognition before actual cut-in occurs, enabling collision avoidance while the system can then accurately track and respond only when genuine cut-in intention is detected, avoiding unnecessary continuous deceleration.
Solution Approach 2:
The system continuously monitors the surrounding vehicle's position, speed, and environmental context (road type, lane information) to provide feedback on cut-in intention. This feedback mechanism allows the system to adjust the distance maintenance dynamically - increasing distance when cut-in is likely in merging/diverging sections, and maintaining normal following distance when no cut-in intention is detected, thereby balancing collision avoidance with driver comfort.
3Measurement precision
If conventional vehicles utilize environmental information only near merging or diverging lanes, then the system complexity is low, but the accuracy of cut-in determination is insufficient in other road sections
Solution Approach 1:
The patent makes the environmental information utilization system universal by enabling it to process and respond to various road section types (merging sections, diverging sections, straight sections, curved sections) using the same navigation module and determination algorithm. The system adapts its behavior based on the detected road section type, making it versatile across different driving scenarios while maintaining consistent accuracy in determining cut-in intention.
