Solution Overview

Problem

In shared vehicle systems, users often need to perform manual selection operations for parking methods even when another user has already set them, leading to inconvenience and annoyance.

Innovation Solution

A parking assistance system that stores parking methods associated with specific parking sections and automatically proposes the stored method to subsequent users based on position information, reducing the need for repetitive selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If driver parameters are learned and stored for specific drivers, then convenience for identified drivers is improved, but users sharing a vehicle still need to perform manual selection operations

Engineering Contradiction:
Improveconvenience for identified driversVSAvoidusability for shared vehicle users
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system automatically performs the selection operation by itself using stored parking parameters for the parking section, without requiring the user to manually select a parking method. The control device executes the parking control based on previously stored parameters when the vehicle is parked in the same section, making the system serve itself rather than requiring user intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system stores parking parameters (parking method, trajectory, etc.) in advance for each parking section before the user needs them again. When the vehicle is parked in the same section, the pre-stored parameters are automatically retrieved and used, eliminating the need for repetitive manual selection operations.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If manual selection operation is required for each parking attempt, then user control is maintained, but operation time and user effort increase

Engineering Contradiction:
Improveuser controlVSAvoidoperation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The control device automatically executes parking control based on stored parameters without requiring manual selection operations from the user. The system identifies the current parking section, retrieves pre-stored parameters for that section, and automatically performs the parking maneuver, significantly reducing operation time while maintaining reliability through automatic execution.

Inventive Principle:
Principle #25Self-service

3Productivity

If parking parameters are stored for each parking section, then repetitive operations are eliminated, but system complexity increases

Engineering Contradiction:
Improveparking operation efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system creates and stores copies of parking parameters (parking method, trajectory, control settings) for each parking section. These parameter copies are saved in the storage device and automatically retrieved when the vehicle is parked in the same section, eliminating repetitive operations without requiring complex real-time processing during actual parking execution.

Inventive Principle:
Principle #26Copying

AI summary

To increase convenience, provided is a system including a device which executes control of executing an automatically parking a vehicle or causing the vehicle to automatically exit based on a method selected by a user. The device includes: a storage module which stores, in association with position information on a specific section, a parking method selected by a first user when the first user executes parking the vehicle in the specific section or causing the vehicle to exit from the specific section; a determination module which determines, when a second user executes parking the vehicle in a predetermined section or causing the vehicle to exit from the predetermined section, whether the predetermined section is the specific section; and a processing module which executes proposing, when the determination module determines that the predetermined section is the specific section, to the second user, the parking method stored in the storage module.
