AR Vehicle Parking Assistant for Digital Twin Space Checking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle parking assistance systems face challenges in determining if a parking space is sufficient for a vehicle, especially when non-standard positions or attached objects are involved, which can lead to potential damage during parking.
Innovation Solution
A digitally enhanced customized vehicle entry and parking assistant system using Augmented Reality (AR) technology, including a Vehicle Platform, Attachment Sensing Device, and Automatic Parking System, creates a virtual digital twin of the vehicle to determine if a parking space is large enough, allowing drivers to position the vehicle virtually and adjust for personal preferences before autonomous parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a driver manually parks a vehicle in a narrow space, then the driver can control the vehicle position and path, but the parking process becomes time-consuming and may cause damage due to human error
Solution Approach 1:
The system performs a virtual parking simulation before actual parking to determine the optimal path and verify space sufficiency. This preliminary virtual action allows the system to plan the parking maneuver in advance, ensuring safety while automating the process to reduce time consumption.
Solution Approach 2:
The system creates a virtual copy (digital twin) of the vehicle and parking environment to simulate the parking process. This virtual model allows for risk-free testing of parking paths and space adequacy, improving reliability by identifying potential collisions before real-world execution.
2Ease of operation
If the system uses a standardized vehicle position for parking, then the parking process is simplified, but the driver's preference for non-centered positions cannot be accommodated
Solution Approach 1:
The system dynamically adjusts the virtual vehicle model's position and orientation based on driver preferences and parking space characteristics. Rather than enforcing a fixed standardized position, the system adapts the parking configuration to accommodate non-centered positions and driver-specific requirements while maintaining operational simplicity.
Solution Approach 2:
The system allows different parts of the parking process to have different characteristics - standardized procedures for safe critical operations (like collision avoidance) while allowing flexibility in less critical aspects (like lateral positioning within the space) to accommodate driver preferences.
3Device complexity
If the system does not detect attached objects on the vehicle, then the system complexity is reduced, but attached objects may cause damage during parking
Solution Approach 1:
The system performs preliminary detection of attached objects (such as roof racks, cargo boxes, or bicycles) before the virtual parking simulation. This early detection allows the virtual model to include these attachments, enabling the system to identify potential collisions with parking structures without significantly increasing system complexity.
Solution Approach 2:
The system uses sensors (such as cameras or radar) as intermediaries to detect attached objects on the vehicle. These sensors provide information about the vehicle's actual dimensions and protrusions, allowing the virtual model to accurately represent the vehicle including attachments, thereby identifying collision risks without requiring complex manual intervention.
4Device complexity
If the system determines parking space sufficiency using traditional methods, then the process is simple, but the system cannot accurately determine if the space is large enough for the vehicle
Solution Approach 1:
The system creates a virtual copy of the parking space and vehicle to perform accurate measurements and collision detection. This virtual model allows for precise determination of whether the space is sufficient by simulating the vehicle's entry and positioning, providing measurement precision that exceeds traditional manual or simplified automated methods.
Solution Approach 2:
The system transitions from two-dimensional parking space markings to three-dimensional virtual modeling, enabling accurate assessment of vertical clearance, lateral space, and depth requirements. This dimensional enhancement allows the system to account for vehicle height, attachment protrusions, and complex parking geometry that traditional methods cannot accurately measure.
