Automatic Parking Sensor Backup Using a Mobile Detection Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic parking systems, when infrastructure sensors such as cameras fail or become abnormal, it becomes difficult to calculate travel routes for vehicles, leading to the interruption of automatic parking services.
Innovation Solution
An automatic parking lot management system that employs a mobile body, such as an autonomous vehicle or drone, equipped with peripheral detection sensors to replace the failed infrastructure sensors by moving to a detectable position and continuing the detection of the affected range.

Engineering Contradiction Analysis
1Reliability
If infrastructure sensors are used to detect the parking lot range, then the automatic parking service can operate normally, but when an abnormality occurs in the infrastructure sensor, the service must be stopped
Solution Approach 1:
A mobile body (autonomous vehicle or drone) equipped with a peripheral detection sensor acts as an intermediary to detect the infrastructure sensor's detection range when the infrastructure sensor becomes abnormal. This mobile body moves to a detectable position and uses its peripheral detection sensor to capture images of the detection range, allowing the server to continue calculating travel routes without service interruption.
2Reliability
If a mobile body with peripheral detection sensor is introduced to detect infrastructure sensor range, then service continuity is maintained during sensor abnormalities, but system complexity increases
Solution Approach 1:
The mobile body serves multiple functions: it acts as both an autonomous vehicle/drone for normal operations and as an alternative detection device when infrastructure sensors fail. By utilizing existing mobile bodies already present in the parking lot system rather than introducing dedicated backup sensors, the solution maintains reliability while minimizing additional system complexity.

AI summary
An automatic parking lot management system includes an infrastructure sensor for detecting a preset range in a parking lot. A mobile body including a peripheral detection sensor is used, and the mobile body is able to be moved to a detectable position at which the peripheral detection sensor of the mobile body is able to detect a detection range of the infrastructure sensor. When determination is made that there is an abnormality in the infrastructure sensor, the mobile body is moved to the detectable position to cause the peripheral detection sensor to detect the detection range of the infrastructure sensor.
