Solution Overview

Problem

Existing automated valet driving systems (AVDS) lack the capability to efficiently manage additional services such as EV charging and car washing during automated valet parking, and they do not define methods for sending a vehicle to an EV charging station before the previous EV's charging is completed, leading to inefficiencies in service provision.

Innovation Solution

The proposed apparatus and method enable the transmission of additional requests for AVDS reservations, allowing changes or additions to existing reservations, and include communication protocols for interacting with EV charging stations to optimize vehicle routing and service timing, ensuring efficient and safe automated valet driving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system waits for previous EV charging to complete before routing vehicles to charging stations, then charging safety is ensured, but service efficiency and productivity deteriorate

Engineering Contradiction:
Improvecharging safetyVSAvoidservice efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary actions by sending vehicles to charging stations in advance before previous charging completes. The server receives additional requests and determines routing information proactively, allowing vehicles to be positioned at charging stations ahead of time, thus improving service efficiency while maintaining safety through controlled dispatch timing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts vehicle routing based on real-time charging status. The server monitors whether previous EV charging has completed and dynamically determines when to send additional vehicles to charging stations, creating a flexible response that balances safety requirements with service efficiency improvements.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the system manages multiple additional services (EV charging, car washing) simultaneously, then service versatility improves, but system complexity increases

Engineering Contradiction:
Improveservice versatilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The server is designed with universal functionality to manage multiple types of additional services including EV charging, car washing, and other services. The system uses a unified request processing mechanism that can handle different service types through additional requests, providing multi-functionality without requiring separate dedicated systems for each service.

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

Solution Approach 2:

The server acts as an intermediary that coordinates between vehicles, charging stations, and other service providers. It receives additional requests from vehicles, determines appropriate routing and timing, and manages the overall service coordination, thereby reducing the complexity burden on individual service components while maintaining versatile service capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the system allows additional service requests during automated valet parking, then customer convenience improves, but communication complexity increases

Engineering Contradiction:
Improvecustomer convenienceVSAvoidcommunication complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables self-service by allowing vehicles to autonomously send additional requests for services such as EV charging and car washing during automated valet parking. The vehicle's onboard system can independently communicate service needs to the server without requiring manual customer intervention, improving convenience while using standardized communication protocols to manage complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The server provides feedback mechanisms to confirm receipt and processing of additional requests. The system communicates request status and service arrangement information back to vehicles, creating a closed-loop communication system that enhances customer convenience through clear status information while managing communication complexity through structured feedback protocols.

Inventive Principle:
Principle #23Feedback
