Solution Overview

Problem

Conventional parking control systems for autonomous vehicles fail to quickly and safely guide them to empty parking spaces, leading to congestion and inefficiencies due to lack of real-time monitoring and accurate route calculation, and often result in incorrect assignment of parking spaces.

Innovation Solution

A parking control system that uses a 3D electronic map to monitor and manage the location and movement of autonomous vehicles, providing a driving trajectory and guiding route to selected parking spaces, with the option for direct parking or autonomous valet parking, and preventing reassignment of spaces once occupied.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a conventional parking control system provides only a guiding route from current location to empty parking space, then the system structure is simple, but the autonomous vehicle cannot move quickly and safely to the parking space

Engineering Contradiction:
Improvespeed of moving to parking spaceVSAvoidcomplexity of parking control system
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The system segments the parking control function into two parts: a central server that performs complex computation and route calculation, and autonomous vehicles that execute navigation. This segmentation allows the vehicle to move quickly using pre-calculated driving trajectories while the complex computation is handled by the server, resolving the contradiction between speed and system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The server performs preliminary actions by calculating driving trajectories and guiding routes in advance before the vehicle begins movement. By pre-processing the complex computation and providing ready-to-execute navigation instructions, the system enables the vehicle to move quickly without performing complex computations in real-time, thus resolving the contradiction between speed and complexity.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the conventional parking control system assigns any empty parking space to autonomous vehicle, then the assignment process is simple, but the vehicle fails in parking when another autonomous vehicle occupies the assigned space

Engineering Contradiction:
Improvereliability of parking assignmentVSAvoidcomplexity of monitoring system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The server implements a feedback mechanism by monitoring the parking lot environment in real-time using sensor data and updating the parking space assignment based on current vehicle locations. When a parking space becomes occupied, the system receives feedback and reassigns alternative spaces, ensuring reliable parking completion while managing complexity through centralized coordination.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The server acts as an intermediary between autonomous vehicles and parking spaces, managing assignments and coordinating movements to prevent conflicts. This intermediary role allows multiple vehicles to be assigned parking spaces reliably without direct vehicle-to-vehicle communication, resolving the contradiction between reliability and system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the conventional parking control system does not monitor vehicle locations in real time, then the system operation is simple, but congestion occurs in the parking lot and parking time increases

Engineering Contradiction:
Improveparking efficiencyVSAvoidcomplexity of real-time monitoring system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The server performs multiple functions including route calculation, real-time monitoring of vehicle locations, dynamic reassignment of parking spaces, and traffic flow management. By consolidating these diverse functions into a single multi-functional system, the patent achieves high parking efficiency through coordinated control while managing complexity through centralized architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adjusts parking space assignments and driving trajectories based on real-time vehicle locations and parking lot conditions. This dynamic adaptation allows the system to prevent congestion and optimize parking efficiency by responding to changing conditions, resolving the contradiction between productivity and system complexity.

Inventive Principle:
Principle #15Dynamics

AI summary

A parking control system for an autonomous vehicle is provided. The parking control system includes a parking control device configured to monitor a location and movement of an autonomous vehicle which enters a parking lot, based on a 3D electronic map, calculate a driving trajectory to a parking space selected by a driver of the autonomous vehicle based on sensor data collected from various sensor in the parking lot and vehicle information received from the autonomous vehicle, and provide information about the calculated driving trajectory to the autonomous vehicle. The autonomous vehicle travels to the parking space based on the driving trajectory received from the parking control device and parks in the parking space.
