Solution Overview

Problem

Conventional automatic parking systems face inaccuracies in determining available parking spaces, leading to failure in parking path generation due to unforeseen conditions, resulting in wasted resources and reduced success rates.

Innovation Solution

The method involves continuously determining available parking spaces while the vehicle is traveling, acquiring and updating parking space and vehicle position information in real-time, and dynamically updating candidate parking spaces based on changing conditions to ensure accurate selection and utilization of available spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional automatic parking systems determine candidate parking spaces based on initial visual frames and ultrasonic line segments, then the parking process is simplified and executed quickly, but the determination accuracy is insufficient leading to failure in parking path generation due to unforeseen conditions

Engineering Contradiction:
Improveparking path generation success rateVSAvoidreal-time detection and updating mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system transitions from static parking space determination based on initial sensor data to dynamic real-time updating of candidate parking spaces during vehicle movement. The control device continuously receives updated position information from sensors and recalculates candidate parking spaces dynamically, allowing the system to adapt to changing road conditions and unforeseen obstacles, thereby improving parking path generation success rate without excessive complexity increase

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a feedback mechanism where the control device continuously monitors vehicle position information and parking space conditions during the parking process. Based on this feedback, the system updates the candidate parking spaces in real-time and adjusts the parking path generation accordingly. This closed-loop feedback ensures that the parking system can respond to unforeseen conditions and maintain high reliability without requiring overly complex preliminary analysis

Inventive Principle:
Principle #23Feedback

2Productivity

If the system preliminarily determines candidate parking spaces before parking path generation, then the parking process is efficient, but available parking spaces may be ignored when conditions change, resulting in resource waste and reduced parking success rate

Engineering Contradiction:
Improveparking execution efficiencyVSAvoidavailable parking space information
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system maintains continuous detection and updating of parking space information throughout the parking process rather than performing a one-time determination. The control device continuously receives vehicle position information and updates candidate parking spaces in real-time, ensuring that available parking spaces are not missed due to condition changes. This continuous action preserves productivity by enabling quick parking execution while preventing information loss about available spaces

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system performs preliminary identification of potential parking spaces before final candidate selection, but maintains the flexibility to update this preliminary list during vehicle movement. By continuously monitoring and updating candidate parking spaces based on real-time position information, the system ensures that spaces that initially appeared unavailable may be added to the candidate list if conditions change, thus preventing resource waste while maintaining efficient parking execution

Inventive Principle:
Principle #10Preliminary action
