Global AVDS Server Coordination for Valet Access and Service Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated valet driving systems lack an efficient method for controlling vehicle access, reservation, check-in, and handover processes across global and local servers, which hinders seamless integration with value-added services like charging stations and car washes.
Innovation Solution
A method and apparatus that enable a global AVDS server to manage local AVDS servers, facilitating data transmission and control of autonomous driving functions, including reservation, check-in, and handover, by integrating with vehicle and user backends, and value-added systems like charging stations and car washes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a global AVDS server manages multiple local AVDS servers with centralized control, then system coordination and service integration are improved, but system complexity and communication overhead increase
Solution Approach 1:
The system divides the AVDS functionality into a global server that handles high-level coordination, reservation management, and service integration, while local servers handle region-specific autonomous driving operations. This segmentation allows centralized service integration without overwhelming any single component with all decision-making complexity.
Solution Approach 2:
The global AVDS server acts as an intermediary between users, local AVDS servers, and value-added services (charging stations, car washes). It receives service requests, coordinates with appropriate local servers, and manages the overall workflow, thereby integrating diverse services without requiring direct complex connections between all system components.
2Measurement precision
If real-time data transmission between global and local servers is implemented, then autonomous driving control accuracy is improved, but communication time and network bandwidth consumption increase
Solution Approach 1:
The system performs preliminary actions by having the global server pre-coordinate service reservations, check-in procedures, and handover arrangements before the actual autonomous driving operations begin. This allows real-time data transmission to focus only on critical control updates during operation, reducing overall communication time while maintaining control accuracy.
Solution Approach 2:
Instead of continuous real-time transmission, the system uses periodic status updates and event-triggered communications between global and local servers. Critical control data is transmitted when needed (e.g., during handover, reservation changes, or service transitions), reducing network bandwidth consumption while maintaining sufficient control accuracy.
3Ease of operation
If comprehensive service management including charging stations and car washes is integrated, then user satisfaction is improved, but operational complexity and management overhead increase
Solution Approach 1:
The global AVDS server implements a universal service management platform that handles multiple service types (parking, charging, car wash, maintenance) through a single integrated interface. This allows users to access diverse services without dealing with separate management systems, improving ease of operation while the server abstracts the underlying complexity of coordinating different service providers.

AI summary
A method for controlling automated valet driving system (AVDS) access of a subject vehicle (SV) by a global AVDS server, and an apparatus therefor. The method includes transmitting and receiving information between a global AVDS server and at least one local AVDS server; controlling autonomous driving of the subject vehicle (SV), wherein the global AVDS server manages each local AVDS server, transmits/receives data to/from at least one of a vehicle backend (VB) and a user backend (UB), wherein the at least one local AVDS server is a sub-AVDS server and the at least one local AVDS server transmits/receives data to/from at least one of the global AVDS server or a value added system (VA), and wherein the VA includes at least one of a charging station for the SV and a car wash for the SV.
