Blind Spot Obstacle Tracking for False Detection Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surroundings monitoring systems may erroneously detect a single obstacle as two, leading to continuous recognition of an obstacle in the blind spot area, which can result in unnecessary prohibition of lane change and parking assistance.
Innovation Solution
A surroundings monitoring apparatus with a detection unit and a tracking unit that determines if a first obstacle is entering a blind spot area and, once a second obstacle has passed that area, concludes the first obstacle is not present, thereby avoiding false detection and enabling accurate lane change and parking assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection unit continuously monitors the blind spot area, then the reliability of obstacle detection is improved, but false detection occurs where a single obstacle is erroneously recognized as multiple obstacles
Solution Approach 1:
The tracking unit performs preliminary tracking of obstacle positions and predicts movement trajectories before the obstacle actually enters or leaves the blind spot area. By pre-establishing tracking data and movement patterns, the system can distinguish between genuine multiple obstacles and false detections of a single obstacle, thereby maintaining detection reliability while improving measurement precision.
2Reliability
If the system prohibits lane change assistance when an obstacle is detected in the blind spot area, then safety is improved, but unnecessary prohibitions occur due to false detections
Solution Approach 1:
The system implements feedback mechanisms where the tracking unit continuously monitors obstacle movement and provides updated information to the lane changeability determination unit. When tracking data indicates that an obstacle has moved out of the blind spot area or that the detection was a false positive, the feedback loop allows the system to clear the prohibition and restore lane change assistance, thereby maintaining safety while reducing unnecessary prohibitions.
3Reliability
If the detection unit maintains continuous monitoring of the surroundings, then the reliability of drive assistance is improved, but false recognition of obstacles in the blind spot area occurs
Solution Approach 1:
The tracking unit serves as an intermediary between the detection unit and the drive assistance control unit. It processes raw detection data, applies tracking algorithms to distinguish genuine obstacles from false detections, and provides refined information to the control unit. This intermediary processing layer maintains drive assistance reliability while preventing loss of accurate obstacle presence information by filtering out false positives.

AI summary
A surroundings monitoring apparatus includes a detection unit configured to detect information on the surroundings of a host vehicle and a tracking unit configured to track a position and a speed of an obstacle in the surroundings of the host vehicle based on the result of detection by the detection unit. The tracking unit is configured to determine whether or not a tracked first obstacle is entering a blind spot area of the detection unit. In a case where it is determined that the first obstacle is entering the blind spot area of the detection unit and when a tracked second obstacle has passed the blind spot area where the first obstacle entered, the tracking unit determines that the first obstacle is not present in the blind spot area.
