Solution Overview

Problem

Current parking assistance systems lack the ability to remotely control vehicles for both forward and reverse parking directions, limiting their functionality and user convenience, especially in various types of parking spaces such as head, side-limited, and parallel parking.

Innovation Solution

A remote-controlled parking assistance system that includes a receiving device for user-selected travel direction and a control device capable of independently determining the type of parking situation, allowing the vehicle to park or exit a space in either direction without additional user input, using environmental sensors and decision logic to adjust steering behavior based on the selected direction and vehicle position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the parking assistance system always reverses without steering during reverse movement, then the system is simple to operate for forward parking, but the system cannot successfully perform reverse direction parking maneuvers

Engineering Contradiction:
Improveoperation simplicityVSAvoidparking direction flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts steering behavior based on the detected parking situation. During forward movement, the vehicle steers automatically to align with the parking space. During reverse movement, the system determines whether to steer or move straight based on the parking configuration, enabling both forward and reverse parking directions while maintaining ease of operation through automated decision-making.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If the system requires additional user input to specify parking situation type, then the system can accurately distinguish parking scenarios, but the user experience becomes more complex

Engineering Contradiction:
Improveparking situation recognition accuracyVSAvoiduser input requirements
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The control device automatically determines the parking situation type (parking situation vs. parking exit situation) based on sensor data and vehicle position without requiring user input. The system uses environmental sensors to detect obstacles and calculates the vehicle's position relative to the parking space, autonomously deciding whether the user intends to park or exit the parking space.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors vehicle position, movement direction, and environmental obstacles using sensors, and uses this feedback to automatically determine the parking situation type. The control device adjusts steering and movement commands based on real-time feedback from the sensor system, enabling accurate situation recognition without additional user input.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the vehicle positions itself as centrally and directly in front of the parking space, then remote-controlled parking can be activated, but the system lacks flexibility for various parking space configurations

Engineering Contradiction:
Improveremote-controlled parking activationVSAvoidparking space configuration flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts its steering and movement strategy based on the detected parking space configuration and vehicle position. Environmental sensors detect the parking space boundaries and obstacles, and the control device calculates appropriate steering angles and movement paths to guide the vehicle into the parking space regardless of the initial positioning or parking space type (head, side-limited, or parallel parking).

Inventive Principle:
Principle #15Dynamics

AI summary

One aspect of the invention relates to a parking assistance system which can be remote-controlled from outside a motor vehicle and has a remote-controlled parking function for automated parking and exiting from a parking space with at least automated longitudinal guidance into and respectively out of a parking space. This is preferably a forward parking space (e.g. a garage). The parking assistance system permits parking in the forward parking direction or rearward parking direction depending on the position of the parking space with respect to the vehicle in question. The parking assistance system comprises a receiver device for receiving a movement direction of the vehicle selected by the user. The receiver device can receive as the movement direction (selected by the user) a selected forward driving movement direction for driving the vehicle forwards or a rearward driving movement direction for driving the vehicle in reverse depending on the user's choice. In addition, a control device which is coupled to the receiver device is provided, which control device is configured to decide independently - without the user making any specification about the presence of a parking situation or parking-space-exiting situation - whether there is a parking situation or parking-space-exiting situation. If the control device detects the presence of a parking situation, the vehicle is parked in the parking space in accordance with the received selected movement direction by means of forward driving or driving in reverse. On the other hand, if the control device detects the presence of a parking-space-exiting situation, the vehicle is made to exit the parking space in accordance with the received selected movement direction by means of forward driving or driving in reverse.
