Solution Overview

Problem

Current automatic parking systems do not allow users to choose their preferred parking space, and if a space is missed, the vehicle must manually return to the vicinity and wait for re-identification before parking.

Innovation Solution

A vehicle-mounted control system that detects reachable parking spaces, stores their positions, and allows users to select a target parking space via a display interface, enabling intelligent automatic parking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the automatic parking system directly parks the vehicle into the first identified usable parking space, then the parking process is simple and fast, but the user cannot choose their preferred parking space

Engineering Contradiction:
ImproveUser ability to choose parking spaceVSAvoidParking system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary detection and caching of multiple usable parking spaces before the user makes a selection. The controller detects parking spaces in advance, stores their position information in a cache, and presents options to the user before execution, allowing informed choice without complicating the actual parking operation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cache acts as an intermediary data structure between the parking space detection system and the user interface. It temporarily stores position information of detected parking spaces, enabling the user to review and select from multiple options before the system executes the parking maneuver

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the vehicle manually returns to the vicinity of a missed parking space, then the user can attempt to park again, but this wastes time and reduces parking efficiency

Engineering Contradiction:
ImproveAbility to park in previously missed spacesVSAvoidTime to re-park in missed space
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection and caching of multiple usable parking spaces in advance, storing their position information before the user has a chance to miss them. This allows the user to select from previously detected spaces even after driving past them, eliminating the need to manually return

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a digital copy (cache) of the detected parking space positions that can be stored and referenced later. This cached information allows the user to select and park in previously detected spaces without physically returning to their original locations

Inventive Principle:
Principle #26Copying

3Ease of operation

If the system caches position information of multiple parking spaces, then user choice is enabled, but the information processing and storage requirements increase

Engineering Contradiction:
ImproveUser selection capabilityVSAvoidParking space data management
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system extracts only the essential position information (coordinates, boundaries) of detected parking spaces and stores it in a cache, separating this critical data from the full detection process. This extracted information is sufficient for user selection and parking execution, reducing storage and processing requirements

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An automatic parking method based on multi-parking space detection and a vehicle-mounted control system are provided. The method includes: detecting (101, 201, 301) a reachable region around a vehicle, and detecting one or more usable parking spaces in the reachable region; obtaining (102, 202, 302) a position of each of the one or more usable parking spaces and storing the position of each of the one or more usable parking spaces in a cache, and determining (103, 203, 303) at least one of the one or more usable parking spaces as at least one candidate usable parking space; receiving (104, 206, 304) a selection instruction for the at least one candidate usable parking space to determine a target parking space; and controlling (105, 207, 309) the vehicle to park at the position of the target parking space. With the above method, a user can choose a parking space based on his/her intention, such that the automatic parking processing can be made more intelligent.
