Solution Overview

Problem

Conventional parking assist apparatuses fail to provide an effective function for users to monitor the target parking space during autonomous parking control, as the target parking space is not adequately displayed on the setting screen and camera viewpoint image, making it difficult for users to visualize and adjust the parking position.

Innovation Solution

The parking assist apparatus includes a camera device, a display, and a control unit that captures images around the vehicle, produces a virtual viewpoint image from a virtual viewpoint located obliquely above the vehicle, and displays a target parking space frame on the display to clearly show the tentative target parking space, allowing users to easily recognize and adjust the parking position, even when the vehicle is at a parking start position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the conventional apparatus displays the target parking space on the setting screen and camera viewpoint image, then the autonomous parking control function is provided, but the target parking space is not displayed largely making it difficult for users to monitor and adjust the parking position

Engineering Contradiction:
Improvevisibility of target parking spaceVSAvoiduser ability to monitor and adjust parking position
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent introduces a virtual viewpoint located obliquely above the vehicle, creating a three-dimensional perspective that projects the target parking space onto a two-dimensional display. This dimensional transformation allows the target parking space to be displayed in an enlarged and visually distinct manner, solving the problem of insufficient visibility while maintaining accurate spatial relationships.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent employs a virtual viewpoint as an intermediary between the actual parking space and the user's perception. This virtual viewpoint acts as a mediator that transforms the real-world three-dimensional parking environment into an optimized two-dimensional representation, enabling users to clearly monitor and adjust the target parking space without directly observing the physical scene.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the parking space setting frame is moved within the bird's-eye view image according to vehicle movement, then the parking space can be selected, but the target parking space remains small and hard to recognize

Engineering Contradiction:
Improveparking space selection capabilityVSAvoiddisplay size of target parking space
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

By introducing a virtual viewpoint positioned obliquely above the vehicle, the system transforms the conventional top-down bird's-eye view into a three-dimensional perspective projection. This dimensional change enables the target parking space to be displayed in an enlarged format while maintaining accurate spatial relationships, allowing users to clearly recognize the parking space position and dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent applies local quality by displaying the target parking space with enhanced visual characteristics in the virtual viewpoint image. The parking space frame is superimposed on the virtual viewpoint image with specific positioning and scaling, creating a localized enhancement that draws user attention to the target area while preserving the overall contextual information.

Inventive Principle:
Principle #3Local quality

AI summary

A parking assist apparatus includes an ECU. The ECU displays a first left support image on a predetermined display area of a touch panel display section so that an entire area of a tentative target parking space is displayed within the predetermined display area, based on a relative position of the tentative target parking space with respect to a vehicle.
