Solution Overview

Problem

Existing parking assistance technologies require manual activation near the target parking position, leading to inefficiencies and potential annoyance when the user does not intend to park.

Innovation Solution

A parking assistance method that initiates preparations based on learning the driver's travel route, determining the vehicle's orientation, and providing notifications to start parking assistance before reaching the target position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If parking assistance preparations are started early before the vehicle arrives near the target parking position, then the productivity of parking assistance is improved, but the user may be annoyed by unnecessary guidance notifications

Engineering Contradiction:
Improveparking assistance preparation timingVSAvoiduser annoyance from unnecessary notifications
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by determining whether the vehicle is likely to park at a target parking position before the vehicle actually arrives near it. This early determination allows parking assistance preparations to start in advance, improving productivity while avoiding unnecessary notifications by only activating them when parking is actually intended.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from sensor data and vehicle state information to continuously assess whether the vehicle is likely to park at the target position. This feedback mechanism allows the system to adjust notification timing dynamically, starting preparations early when appropriate while suppressing notifications when the user has no intention of parking, thereby avoiding user annoyance.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the vehicle must arrive near the target parking position before starting parking assistance, then the ease of operation is improved, but the loss of time increases

Engineering Contradiction:
Improveparking assistance activation conditionVSAvoidtime to start automatic parking
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary determination of parking intention using sensor data and vehicle state information before the vehicle arrives near the target parking position. This allows parking assistance to be prepared in advance, reducing the time loss while maintaining ease of operation by only activating when the system determines parking is actually intended.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the activation conditions for parking assistance based on real-time vehicle state and sensor data. Rather than using a fixed threshold distance, the system adaptively determines when to start preparations, balancing ease of operation with time efficiency by activating early only when parking is actually intended.

Inventive Principle:
Principle #15Dynamics

AI summary

A parking assistance method is provided, which performs autonomous travel of a vehicle based on a teaching travel by a driver. The parking assistance method: stores a traveling route traveled by the vehicle according to a driving operation of the driver; displays first image information representing a start position of the traveling route in a first display mode; and displays second image information representing a parking position of the traveling route in a second display mode different from the first display mode.
