Remote Parking Path Control Around the Vehicle User
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems fail to account for the position of the vehicle user when they are outside the vehicle, leading to potential collisions and inconvenient emergency braking situations, as the user may not be aware of the vehicle's movement path or target position.
Innovation Solution
A method that continuously monitors the vehicle user's position and adjusts the parking trajectory and target position to avoid collisions, allowing for real-time replanning of the parking process based on the user's location, and provides visual or acoustic instructions for the user to change their position if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the parking assistance system maneuvers the vehicle remotely without considering the vehicle user's position, then the parking operation can be completed efficiently, but the vehicle user may be in the vehicle's trajectory or at the target position causing collision risks
Solution Approach 1:
The system determines a provisional vehicle target position and trajectory before executing the parking maneuver, then checks whether this provisional path causes collision with the vehicle user. This preliminary check allows the system to identify and correct potential collision risks before the vehicle actually moves, maintaining both efficiency and safety.
Solution Approach 2:
The system continuously monitors the vehicle user's position during the parking operation and uses this feedback to determine whether to proceed with the provisional target position or to request user repositioning. This feedback mechanism ensures that the parking operation adapts to real-time conditions, preventing collisions while maintaining operational flow.
2Reliability
If the parking assistance system checks the vehicle user's position and adjusts the trajectory to avoid collisions, then collision risk is reduced, but the parking process becomes more complex
Solution Approach 1:
The vehicle user themselves serves as the reference for determining whether a collision risk exists. The system detects the user's position and uses this information to make autonomous decisions about trajectory adjustment, eliminating the need for additional complex sensor systems or external monitoring infrastructure.
Solution Approach 2:
The system implements a simplified collision check that focuses specifically on whether the vehicle user is in the trajectory or at the target position, rather than performing a comprehensive environmental scan. This partial check provides sufficient safety for the specific use case while keeping the system relatively simple.
3Reliability
If the system requests the vehicle user to change position when a collision is detected, then safety is improved, but the user experiences inconvenience and the process takes longer
Solution Approach 1:
The system takes preliminary action to prevent the harmful effect (collision) by detecting potential collision risks before they occur and requesting user repositioning in advance. This prevents the more severe consequence of emergency braking and collision, even though it requires the user to move temporarily.
Solution Approach 2:
The system provides a buffer by detecting collision risks in advance and giving the user opportunity to reposition before the vehicle executes the maneuver. This cushioning approach prevents the harsher outcome of emergency stopping and potential collision, maintaining user safety and comfort.

AI summary
The invention relates to a method for controlling a parking operation of a vehicle (1) by means of a parking assistance system (4), comprising the following steps: capturing the position of a vehicle user (2) who is located close to but outside of the vehicle; determining a provisional vehicle target position (VZP) and a provisional vehicle motion path (VBB) on the basis of the vehicle starting position (FSP) and the position of the vehicle user (2); checking if the provisional vehicle target position (VZP) and/or the motion of the vehicle into the provisional vehicle target position (VZP) on the provisional vehicle motion path (VBB) causes a collision with the vehicle user (2); changing the provisional vehicle target position (VZP) into a changed vehicle target position (AZP) and/or changing the provisional vehicle motion path (VBB) into a changed vehicle motion path (ABB) if a collision with the vehicle user (2) occurs at the provisional vehicle target position (VZP) or during the motion of the vehicle (1) into the provisional vehicle target position (VZP), the changed vehicle target position (AZP) and/or the changed vehicle motion path (ABB) being selected in such a way that no collision with the vehicle user (2) occurs at the changed vehicle target position (AZP) and/or during the motion of the vehicle (2) on the changed vehicle motion path (ABB).
