Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing automatic parking systems lack a secure and error-proof method for transferring motor vehicles to free parking spaces without drivers, as they are vulnerable to accidental or abusive releases.

Innovation Solution

A procedure where the parking system transmits a release code to the motor vehicle, which the driver must consciously enter into a mobile device to confirm, ensuring that the vehicle is only transferred to a free parking space after explicit authorization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If automatic parking systems transfer vehicles driverlessly without additional authorization steps, then the transfer process is fast and convenient, but the system is vulnerable to accidental or abusive releases

Engineering Contradiction:

Improvesecurity of transfer processVSAvoidcomplexity of authorization process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by transmitting the release code to the motor vehicle before the actual transfer occurs. The driver must consciously enter this code to confirm authorization, ensuring that the transfer is intentional and authorized before the automated process begins.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The release code serves as an intermediary element between the driver and the automatic parking system. This code acts as a mediator that requires conscious driver input while enabling the automated transfer process, thus bridging the gap between manual authorization and automated execution.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the system requires driver confirmation for transfer, then accidental releases are prevented, but the transfer process time increases

Engineering Contradiction:

Improveerror-proof handoverVSAvoidtime for authorization

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system replaces traditional mechanical or physical authorization methods with an electronic communication-based approach. The release code is transmitted electronically to the vehicle and entered through a digital interface, streamlining the confirmation process while maintaining security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The invention relates to a method for transferring a motor vehicle (10) to an automatic parking system (1) which is designed to transfer the motor vehicle (10) to a free parking space (14) of the parking system (1) without a driver. The parking system (1) transmits a release code (C) to the motor vehicle (10), said release code being output in the motor vehicle (10) so as to be perceivable to a motor vehicle user (26). After leaving the motor vehicle (10), the motor vehicle user (26) transmits the release code (C) to the parking system (1) in order to grant a drive release. As soon as the drive release is granted, the motor vehicle (10) is transferred to the free parking space (14) of the parking system (1) without the driver. The invention additionally relates to an automatic parking system (1) and to a motor vehicle (10) for carrying out the method.
