Solution Overview

Problem

Drivers face difficulty in comfortably maneuvering their vehicles to park in garages, especially without dedicated infrastructure for automated valet parking systems, as existing solutions require specific equipment in the parking garage.

Innovation Solution

An automated vehicle method using on-board sensor systems to detect ticket machines and maneuver the vehicle to align closely with them, allowing for fully or partially automated control of longitudinal and lateral movements to obtain a parking ticket without relying on external infrastructure, and can also be used for entering or leaving the garage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If automated valet parking is implemented using external infrastructure (sensor systems, cameras), then the barrier can be automatically opened and the vehicle can drive into the parking garage fully automated, but the parking garage must be equipped with dedicated infrastructure which limits adaptability

Engineering Contradiction:
Improveautomated barrier openingVSAvoidcompatibility with existing parking garages
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The vehicle performs the detection and maneuvering functions itself using its own sensor systems and control units, without requiring the parking garage to provide specialized infrastructure. The vehicle autonomously detects the ticket machine, calculates the maneuver trajectory, and executes the positioning maneuver independently.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Instead of having the parking garage infrastructure detect and guide the vehicle (traditional approach), the invention reverses the detection direction by having the vehicle's own sensors detect the garage's ticket machine and use that information to autonomously maneuver into position.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If drivers manually maneuver the vehicle to the ticket machine, then no special infrastructure is needed, but the driving experience is uncomfortable and requires steering corrections

Engineering Contradiction:
Improvecompatibility with existing parking garagesVSAvoidcomfort of manual maneuvering
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The invention replaces the mechanical steering and positioning actions with an automated control system that uses sensor data, trajectory calculation, and automated steering control to maneuver the vehicle, eliminating the need for manual steering corrections while maintaining compatibility with existing parking garages.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the vehicle positions itself very close to the ticket machine (below 80 cm distance), then the driver can easily reach the button, but precise lateral positioning control is required

Engineering Contradiction:
Improveaccessibility to ticket machineVSAvoidpositioning accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The control unit continuously receives feedback from the sensor system during the maneuvering process, comparing the actual position with the desired trajectory and making real-time adjustments to achieve precise positioning within 80 cm of the ticket machine.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary detection of the ticket machine's exact location and pre-calculates the optimal maneuver trajectory before execution, ensuring that the vehicle will achieve the required positioning accuracy when the maneuver is completed.

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided is a method for automatically driving an automated vehicle into and/or out of a parking garage. The method comprises detecting a ticket machine being installed at an access and/or an exit road of a parking garage using sensor data captured by an on-board sensor system of the vehicle, and maneuvering the vehicle to the detected ticket machine such that a distance between a window of the vehicle next to a driver seat of the vehicle and the detected ticket machine is below 80 cm. The vehicle controls a longitudinal and/or lateral movement of the vehicle during maneuvering the vehicle to the detected ticket machine.
