Vehicle Access via Dynamic Unparking for Tight Parking Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fully automated valet parking systems, vehicles are often parked so closely together that accessing the vehicle interior via doors or trunk is not possible due to insufficient opening space.
Innovation Solution
A method and device that allow temporary access to a vehicle interior by partially unparking the vehicle to open doors or windows, and then re-parking it upon request completion, using communication networks to transmit and receive data for remote or autonomous control of the vehicle's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles are parked closely together to maximize parking area efficiency, then parking area utilization is improved, but access to vehicle interior becomes impossible due to insufficient door opening space
Solution Approach 1:
The vehicle dynamically changes its position between two states: parked in the parking space and pulled out to enable access. The control device receives an access request and automatically controls the vehicle to pull out from the parking space, creating door opening space. After access is completed, the vehicle returns to its original parking position. This dynamic position adjustment resolves the contradiction by temporarily sacrificing parking density to enable access, then restoring it afterward.
2Ease of operation
If the vehicle pulls out completely from the parking position to enable access, then access to vehicle interior is improved, but traffic interference increases
Solution Approach 1:
The vehicle performs a partial pull-out action - just enough to create sufficient door opening space for access, rather than pulling out completely to a driving position. The control device calculates and executes the minimal necessary displacement to enable door opening while keeping the vehicle largely within or near the parking space boundaries. This partial action enables access while minimizing obstruction to surrounding traffic flow.
3Extent of automation
If autonomous parking capabilities are implemented in the vehicle, then access automation is improved, but device complexity and resource demands increase
Solution Approach 1:
An external control device (server or parking management system) acts as an intermediary between the user's access request and the vehicle's parking control system. The control device receives access requests, determines the necessary pull-out parameters, and transmits control signals to the vehicle's existing parking assistance system. This approach enables automation without requiring complex autonomous driving capabilities in the vehicle itself, leveraging external intelligence and the vehicle's existing infrastructure.
Solution Approach 2:
The vehicle uses its own existing parking assistance systems and actuators to perform the pull-out and return movements, rather than requiring a completely new autonomous driving system. The control device leverages the vehicle's existing capability to execute parking maneuvers by transmitting appropriate control commands, allowing the vehicle to service itself using its own hardware resources.
Data Source
AI summary
A method for providing an access option to a vehicle interior of a vehicle parked at a parking position, including receiving an access request for an access to the vehicle interior via a communication network, in response to the received access request, ascertaining unparking data, based on which the vehicle may at least partially leave its parking position, to provide an access option to the vehicle interior by opening a vehicle window and/or a vehicle door, transmitting the ascertained unparking data to the vehicle via the communication network, —receiving a signal via the communication network that the access option is no longer needed, in response to the signal, ascertaining parking data, based on which the vehicle may drive back into its parking position, and transmitting the ascertained parking data to the vehicle via the communication network.
