Automatic Parking Position Registration on Inclined Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic parking systems struggle to accurately register parking positions when the vehicle is parked on an inclined surface, as they do not account for the display shift caused by the incline in the imaging data.
Innovation Solution
A control device equipped with an imaging unit, a reception unit, and a control unit that executes automatic parking control and registers the parking position. When the vehicle stops before reaching the intended parking position, the control unit registers the stop position as the designated parking position, accounting for the distance threshold to correct for incline-related display shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle is parked on an inclined surface using conventional automatic parking systems, then the vehicle can be parked at the intended position, but the parking position registration becomes inaccurate due to display shift in imaging data
Solution Approach 1:
The system uses imaging data to detect the actual parking position and compares it with the intended position, then feeds back the stop position information to correct the registration. This feedback mechanism allows the system to account for display shifts caused by inclined surfaces and accurately register the actual parking position.
Solution Approach 2:
The system changes the registration parameter from the intended parking position to the actual stop position detected by imaging data. By using the stop position as the registration target when the vehicle stops before reaching the intended position, the system adapts to inclined surfaces and maintains registration accuracy.
2Device complexity
If the system registers the intended parking position without correction, then the registration process is simple, but the registered position overlaps with obstacles due to display shift
Solution Approach 1:
The system implements a feedback mechanism that detects when the vehicle stops before reaching the intended position using imaging data, then uses this information to determine the actual stop position. This feedback ensures reliable position registration without excessive complexity by only activating correction when needed.
Solution Approach 2:
The system performs preliminary detection of the stop position using imaging data before finalizing the parking position registration. This preliminary action prevents overlap with obstacles by ensuring the registered position reflects the actual vehicle location.
3Measurement precision
If the system continuously monitors and corrects parking position registration, then registration accuracy improves, but the control process becomes more complex
Solution Approach 1:
The system performs preliminary detection of the stop position using imaging data during the parking process. This preliminary action captures the actual position before final registration, ensuring accuracy without requiring continuous complex corrections throughout the entire parking operation.
Solution Approach 2:
The system uses feedback from imaging data to detect when the vehicle stops, then applies correction only at that specific moment. This targeted feedback approach maintains high registration accuracy while avoiding the complexity of continuous monitoring and adjustment throughout the entire parking process.

AI summary
A control device includes an imaging unit configured to acquire imaging data of surroundings of a moving body, a reception unit configured to receive selection of a predetermined parking position from a user of the moving body, and a control unit configured to execute automatic parking control for parking the moving body at the predetermined parking position based on the imaging data and the predetermined parking position, and to register the predetermined parking position as a designated parking position. When the moving body is stopped after the automatic parking control is started and before the predetermined parking position is reached, the control unit registers a stop position where the moving body is stopped as the designated parking position.
