Parking Management Apparatus Detecting Vehicle Abnormalities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking management systems cannot effectively detect and determine the occurrence of abnormalities in parked vehicles that are not detected by in-vehicle sensors, making it difficult to identify and specify the cause of such abnormalities.
Innovation Solution
A parking management apparatus that uses cameras to capture and compare video information at different zones within a parking lot, determining abnormalities by calculating differences in video data between entry and exit points, and specifying the timing and location of occurrences using video comparison and responsibility determination devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If in-vehicle sensors are used to detect abnormalities, then the detection can be performed by the vehicle's own systems, but abnormalities that cannot be detected by in-vehicle sensors remain undetected
Solution Approach 1:
The patent introduces an external parking management apparatus as an intermediary system that independently monitors parked vehicles using external sensors and cameras. This intermediary system detects abnormalities that the vehicle's own sensors cannot detect, such as external damage or environmental factors, thereby complementing the in-vehicle detection system and reducing information loss.
Solution Approach 2:
The system performs preliminary recording of vehicle states using cameras and sensors before the vehicle exits the parking lot. By capturing images and data in advance during the parking period, the system establishes a baseline that can be compared against post-parking conditions, enabling detection of abnormalities that occurred during parking without requiring continuous real-time detection.
2Quantity of substance
If recording is performed only when abnormalities are detected by in-vehicle sensors, then storage resources are conserved, but no record is stored if the abnormality cannot be detected
Solution Approach 1:
The system performs preliminary recording of vehicle states using cameras and sensors before the vehicle exits the parking lot. By capturing images and data in advance during the parking period, the system establishes a baseline that can be compared against post-parking conditions, enabling detection of abnormalities that occurred during parking without requiring continuous real-time detection.
Solution Approach 2:
The system compares the pre-parking vehicle state information with post-parking information to determine if abnormalities have occurred. This feedback mechanism allows the system to identify changes in vehicle condition by analyzing differences between the recorded baseline state and the current state, triggering appropriate responses only when actual abnormalities are detected through comparison.
3Measurement precision
If comprehensive monitoring is implemented to detect all abnormalities, then detection accuracy improves, but system complexity and cost increase
Solution Approach 1:
The monitoring system is segmented into distinct functional modules: in-vehicle sensors for internal monitoring, external cameras for visual documentation, and a comparison unit for analyzing state changes. Each component has a specific, simplified function, and they work together through a standardized interface, achieving comprehensive monitoring capability while keeping individual component complexity low.

AI summary
A parking management apparatus is configured to manage parking of a vehicle in a parking lot. The parking management apparatus is provided with: a first acquirer configured to obtain first information about a state of the vehicle when the vehicle enters the parking lot; a second acquirer configured to obtain second information about the state when the vehicle exits from the parking lot; and a determinator configured to determine that an abnormality has occurred in the vehicle in the parking lot, when a difference between the first information and the second information exceeds a predetermined allowable range.
