Automatic Parking System Obstacle Removal Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic parking systems, when a vehicle encounters an obstacle during automatic drive control, it may become stuck on the path, hindering the operation and management of the parking lot, as existing systems fail to effectively remove the vehicle from the path to allow other vehicles to travel.
Innovation Solution
The system includes a contact determination unit that, upon detecting an obstacle, causes the vehicle to move to a predetermined removal position using automatic drive control, ensuring it does not interfere with other vehicles, and includes a door lock control unit to manage the vehicle's locking state during and after the automatic drive control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops on the path after contact determination during automatic drive control, then the contact avoidance is achieved, but the path becomes blocked and other vehicles cannot travel
Solution Approach 1:
The system dynamically adjusts the vehicle's final position based on real-time conditions. Instead of always stopping at a fixed position after contact determination, the vehicle is guided to a removal position that is dynamically selected to be away from the current path, ensuring both contact avoidance and path accessibility for other vehicles
Solution Approach 2:
The automatic drive control system acts as an intermediary between the contact determination unit and the vehicle's final positioning. It receives the contact determination signal and mediates the vehicle's movement to an appropriate removal position, rather than allowing direct stopping at the contact point, thus resolving the conflict between safety and path accessibility
2Productivity
If the vehicle is removed to a parking space after contact determination, then the path is cleared for other vehicles, but the vehicle may leave the original parking space unnecessarily
Solution Approach 1:
The system applies different removal strategies based on local conditions. The removal position is determined by evaluating the specific situation - whether the vehicle should return to its original parking space or be moved to a different removal position. This localized decision-making avoids unnecessary relocation while ensuring path accessibility when needed
3Device complexity
If the automatic drive control ends immediately after contact determination, then the control process is simplified, but the vehicle may remain stuck on the path
Solution Approach 1:
The system performs preliminary assessment before ending the control process. After contact determination, the automatic drive control unit evaluates whether the vehicle should be moved to a removal position before allowing the control process to end. This preliminary action prevents the vehicle from remaining stuck on the path while maintaining a relatively simple control structure

AI summary
An automatic parking system is disclosed. The automatic parking system includes: a monitoring device configured to monitor a parking space and a traveling path in a parking lot; an automatic drive unit configured to perform an automatic drive control for a vehicle in the parking lot to move from a current position to a predetermined target position in the parking lot based on a monitoring result of the monitoring device; and a contact determination unit configured to perform a contact determination between the vehicle in the automatic drive control and an obstacle, based on the monitoring result, or the like. In a case where the contact determination is performed by the contact determination unit, the automatic drive unit causes the vehicle to stop, and then, causes the vehicle to move to a removal position and to be parked using the automatic drive control.
