Automated Parking Correction Move for Longitudinal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated parking systems with transverse and longitudinal guidance do not effectively utilize parking space, as they do not consider the longitudinal orientation of the vehicle, leading to wasted space and difficulties in manually exiting the parking space due to improper positioning.
Innovation Solution
The method involves determining the distance from a bounding object at the front of the parking space and performing an additional corrective move with a steering angle of zero degrees to achieve optimal longitudinal orientation, allowing for efficient use of space and easy exit, by moving forward or backward as necessary to maintain a target distance from the bounding object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the vehicle is moved into a final parking position based only on distance from lateral boundary line and vehicle skew, then the parking process is completed with automated guidance, but an unnecessarily large amount of parking space is wasted
Solution Approach 1:
The system performs a first check to determine if the vehicle is oriented parallel to the lateral boundary line and at an admissible distance, then performs a second check to determine the distance from a bounding object at the front. Based on the results of these checks, the system decides whether to perform an additional corrective move, creating a feedback loop that optimizes parking space utilization while maintaining automated operation.
2Extent of automation
If the vehicle is parked in the middle of a large parking space as the final parking position, then the automated parking process is completed, but parking space in front of and behind the vehicle is wasted unnecessarily
Solution Approach 1:
The system performs preliminary checks during the parking process to determine the vehicle's orientation and distance from bounding objects. Based on these preliminary assessments, the system proactively performs an additional corrective move before the parking process is fully completed, ensuring optimal positioning and preventing wasted parking space.
3Productivity
If the distance between the front of the vehicle and the rear of the bounding vehicle parked in front is short, then the automated parking process is efficient, but it may be difficult for the driver to take the vehicle out of the parking space manually later
Solution Approach 1:
The system performs a second check to determine the distance from a bounding object at the front of the parking space. If this distance is insufficient, the system performs an additional corrective move to increase the gap, preemptively preventing the problem of difficult manual vehicle exit while maintaining efficient automated parking.

AI summary
A method performs an automated process for parking a motor vehicle in a longitudinal parking space, wherein the vehicle automatically controls the longitudinal and transverse movement of the vehicle and the vehicle is moved, in one or more moves, into a position in the longitudinal parking space in which the vehicle is aligned in the longitudinal direction substantially parallel to a lateral delimitation line of the longitudinal parking space and is at a permissible distance from the lateral delimitation line of the longitudinal parking space. The method is characterized in that the distance from a front delimiting object of the parking space is determined in the aligned position and, depending on the distance, the vehicle performs an additional correction move, in which the vehicle is moved in the forward or reverse direction under automatic control with a steering angle of substantially zero degrees.
