Self-Parking Vehicle Orientation Correction via Turning Region Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-parking vehicles often exit parking spaces with incorrect orientation, particularly when entering a garage forward and exiting rearward, leading to undesired orientation in the handover zone.
Innovation Solution
A method for operating a self-parking vehicle that involves reading a parking data set and a turning region data set to determine a suitable maneuver for exiting the parking space, using surroundings sensors or user input to adapt the vehicle's orientation by adding a turning maneuver to the data set for exiting, allowing the vehicle to change its orientation during the exit process.

Engineering Contradiction Analysis
1Extent of automation
If the motor vehicle drives the recorded driving route in reverse direction to exit the parking space, then the motor vehicle can automatically exit the parking space, but the motor vehicle is oriented incorrectly in the handover zone
Solution Approach 1:
The system performs preliminary analysis of the driving route during the parking maneuver to identify suitable turning regions beforehand. This allows the exit maneuver to be optimized in advance, ensuring correct vehicle orientation in the handover zone while maintaining automatic operation. The turning region data set is created during the initial parking run, enabling the exit maneuver to be planned with orientation considerations.
Solution Approach 2:
The exit maneuver is divided into multiple segments: a first driving portion in reverse direction and a second driving portion in forward direction with a turning maneuver in between. This segmentation allows the vehicle to maintain automatic operation while correcting its orientation through the intermediate turning phase in the identified turning region.
2Ease of operation
If a turning maneuver is added to the data set for exiting the parking space, then the vehicle orientation can be adapted, but the complexity of the exit maneuver increases
Solution Approach 1:
The turning region data set is determined during the initial parking maneuver or by scanning the surrounding area beforehand. This preliminary action stores turning region information that can be directly utilized during the exit maneuver, avoiding the need for complex real-time calculations and reducing the overall system complexity.
Solution Approach 2:
The parking data set and turning region data set are combined to create a comprehensive exit data set that serves multiple functions: navigation to the handover zone, orientation correction, and automatic control. This multi-functional approach consolidates what would otherwise require separate systems into a unified maneuver plan.

AI summary
While a vehicle is operated from a first area to a second area based on a stored route, one or more turning regions are identified along the stored route based on sensor data. Upon selecting one turning region, a route is determined from the second area to the first area via the selected turning region based on the stored route. Upon receiving a message from a handheld device, the vehicle is actuated to operate along the route and turn around in the selected turning region.
