Vehicle Parking Space Prediction Display System

Solution Overview

Problem

Conventional parking assist systems fail to provide drivers with an image of the target parking space within each parking section, making it difficult for novice or inexperienced drivers to select an optimal empty parking space, especially in challenging conditions like nighttime parking where visibility is limited.

Innovation Solution

A device and method that utilize a parking assist system and top-view imaging system to predict and display the target parking space on a top-view image by acquiring a parking reference point and parking section information, allowing the driver to visualize the optimal parking space within an empty section.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a conventional parking assist system only provides empty parking section information without target parking space prediction, then the system complexity remains low, but the driver cannot accurately select an optimal parking space especially in low-visibility conditions

Engineering Contradiction:

Improvetarget parking space informationVSAvoidsystem complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system performs preliminary prediction of the target parking space by processing the parking reference point and search space width before the driver makes a selection. The controller calculates and displays the predicted target parking space in advance, allowing the driver to make an informed decision without experiencing information loss during the actual parking selection moment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The controller acts as an intermediary between the parking assist system and the display system. It receives the parking reference point and search space width, processes this information to determine the target parking space, and then displays it to the driver. This intermediary processing resolves the contradiction by adding necessary information processing without requiring the entire system to become overly complex.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If the system displays target parking space prediction, then parking accuracy improves, but the information processing complexity increases

Engineering Contradiction:

Improveparking accuracyVSAvoidinformation processing complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary prediction of the target parking space by processing the parking reference point and search space width before the driver makes a selection. The controller calculates and displays the predicted target parking space in advance, allowing the driver to make an informed decision without experiencing information loss during the actual parking selection moment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a visual copy or representation of the predicted target parking space on the display device. Instead of directly manipulating the physical parking process, the controller generates a digital representation showing where the vehicle should be positioned, allowing the driver to verify and select the appropriate parking space before execution.

Inventive Principle:

Principle #26Copying

3Measurement precision

If the system processes parking reference point and search space width to predict target parking space, then parking selection accuracy improves, but the computational requirements increase

Engineering Contradiction:

Improveparking space detection precisionVSAvoidcomputational power

Core Design Contradiction:

Measurement precisionVSPower

Solution Approach 1:

The system performs preliminary prediction of the target parking space by processing the parking reference point and search space width before the driver makes a selection. The controller calculates and displays the predicted target parking space in advance, allowing the driver to make an informed decision without experiencing information loss during the actual parking selection moment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system processes only the essential parameters needed for target parking space prediction (parking reference point and search space width) rather than analyzing all possible environmental factors. This partial processing approach achieves sufficient measurement precision for parking space detection without requiring excessive computational power.

Inventive Principle:

Principle #16Partial or excessive action
