Back-Sideways Alarming System Lane Recognition False Alarm Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back-sideways alarming systems generate false alarms due to their inability to differentiate between actual and unnecessary alarm areas, particularly in road environments with multiple lanes or structures like centerlines and guardrails, leading to reduced driver reliability.
Innovation Solution
A back-sideways alarming system that includes an image acquiring unit, a collecting unit, and an electronic control unit capable of recognizing the driving lane and resetting alarm areas based on road information, thereby generating alarms only when target information enters the valid alarm area, reducing false alarms by distinguishing between lanes and non-alarm areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all predetermined areas around a vehicle are set as alarm areas, then the alarm system can detect all potential threats, but false alarms are generated due to targets outside the actual driving lane such as centerlines, guardrails, or diffused-reflection noise signals
Solution Approach 1:
The alarm area is segmented into multiple lanes based on road information. The electronic control unit recognizes the number of lanes and divides the monitoring area accordingly, so that only relevant lanes are monitored for alarms. This segmentation prevents false alarms from objects in non-driving areas while maintaining detection capability in actual driving lanes.
Solution Approach 2:
The alarm area is dynamically adjusted based on recognized road environment and lane information. The electronic control unit modifies the alarm area configuration in real-time according to the detected number of lanes and vehicle position, making the alarm system adaptive to different road conditions rather than using fixed predetermined areas.
2Ease of operation
If the alarm area is reset according to recognized lane and road information, then false alarms are reduced, but the system complexity increases due to lane recognition and alarm area resetting functions
Solution Approach 1:
The electronic control unit performs multiple functions: it recognizes lanes, determines the number of lanes, analyzes target information, and resets alarm areas all through a single integrated component. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while achieving the desired ease of operation.
Solution Approach 2:
The lane recognition function and alarm area control function are merged into the electronic control unit. Instead of having separate systems for lane detection and alarm management, the patent combines these functions, allowing the same processor to handle both tasks and share computational resources, thus reducing overall system complexity.

AI summary
Provided are a back-sideways alarming system and an alarming control method, which are capable of reducing the generation of a false alarm by detecting a driving road environment of a vehicle and preventing an unnecessary alarm caused by target information generated at a centerline of a road and an outside of a road. The back-sideways alarming system includes: an image acquiring unit configured to acquire road information of a vehicle; a collecting unit configured to collect target information on targets located around the vehicle; and an electronic control unit configured to recognize a lane based on the road information acquired by the image acquiring unit, reset an alarm area according to information on the recognized lane and the road information, and generate an alarm when the target information is located in the reset alarm area.
