Autonomous Parking Safety Controller for Unexpected Incident Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous parking systems lack countermeasures for unexpected incidents during navigation, potentially leading to accidents due to system errors or obstacles detected during the parking slot search process.
Innovation Solution
An apparatus and method for controlling safety in autonomous parking systems, which includes a data collection unit, a brake unit, and a communication unit to stop the vehicle, analyze data for unexpected incidents, and notify the driver, thereby preventing accidents by determining whether to resume navigation or alert the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the autonomous parking system performs autonomous navigation without driver intervention, then the convenience and time efficiency are improved, but the safety risk increases due to lack of driver monitoring
Solution Approach 1:
The system continuously monitors navigation status and obstacle detection results, comparing expected parameters with actual sensor data. When deviations are detected (such as unexpected obstacles or system errors), the feedback loop triggers an emergency stop and notifies the driver, resolving the safety risk while maintaining autonomous operation convenience
Solution Approach 2:
The notification system acts as an intermediary between the autonomous parking system and the driver. It provides real-time information about system status and unexpected incidents, enabling the driver to take over control when necessary while allowing autonomous operation to proceed during normal conditions
2Reliability
If the system continuously monitors for obstacles during autonomous navigation, then the safety is improved, but the system complexity increases
Solution Approach 1:
The monitoring system is integrated into the existing autonomous parking control unit, which also handles navigation control and emergency stopping. This multi-functional approach allows obstacle detection, navigation management, and safety responses to be handled by a single integrated system rather than separate components, reducing overall system complexity
