Vehicle Object Tracking With Integrated-Line ROI Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face issues with misrecognizing objects due to sensor errors or delays, leading to frequent deceleration and reduced ride comfort as they misjudge the movement of objects around the vehicle.
Innovation Solution
A device and method that utilize a sensor to acquire vehicle and road information, create an integrated line, and set a region of interest based on travel data, adjusting this region using critical distances and compensation functions to accurately determine object behavior, even when sensor errors occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle control system uses sensor data to determine object movement, then collision prevention is improved, but false misjudgments occur due to sensor errors or delays causing unnecessary deceleration
Solution Approach 1:
The patent introduces an integrated line as an intermediary reference that combines multiple road line detections over time. This integrated line serves as a mediator between the sensor data and the object movement determination, providing a more stable and accurate reference frame that reduces false positives from sensor errors while maintaining collision prevention capability
Solution Approach 2:
The system performs preliminary actions by creating and updating the integrated line before determining object movement. The integrated line is continuously refined using historical sensor data and road information in advance, so that when object movement is assessed, the reference framework is already optimized, reducing the impact of transient sensor errors
2Reliability
If the system frequently decelerates to prevent collision with misjudged objects, then safety is improved, but ride comfort deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors sensor data, integrated line position, and object trajectories. When an object is detected near the integrated line, the system evaluates multiple factors including sensor reliability indicators, historical data consistency, and predicted trajectories before triggering deceleration. This feedback loop ensures deceleration only occurs when truly necessary, maintaining safety while avoiding unnecessary comfort degradation

AI summary
A device for controlling a vehicle may include a sensor that senses an object around the vehicle and acquires travel information of the vehicle, and a controller that creates an integrated line corresponding to a road where the vehicle is traveling, and sets a region of interest corresponding to the object based on the integrated line, and changes the region of interest based on the travel information of the vehicle.
