AVP-AVC Coordination for Automated Vehicle Battery Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for automated charging and discharging of vehicle batteries in highly automated motor vehicles lack efficient coordination between Automated Valet Parking (AVP) and Automated Valet Charging (AVC) processes, leading to potential inefficiencies and safety risks.
Innovation Solution
A main system coordinates the execution of automated charging and discharging processes by decoupling AVP and AVC systems, ensuring that AVP processes are completed before initiating AVC, allowing separate implementation and operation by different operators, and utilizing environmental sensors for monitoring and safety area management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If AVP and AVC systems are integrated in a single system, then system complexity is reduced, but safety risks and operational conflicts increase due to lack of clear responsibility separation
Solution Approach 1:
The system is segmented into two independent subsystems: AVP system for automated valet parking operations and AVC system for automated valet charging operations. Each system has its own control unit and operates independently, with clear functional boundaries. This segmentation reduces safety risks by preventing operational conflicts while maintaining manageable complexity through modular architecture.
Solution Approach 2:
A main system acts as an intermediary coordinator between the AVP system and AVC system. It receives requests, determines the appropriate system to activate, and manages the transition between parking and charging operations. This mediator ensures clear responsibility separation and coordinated execution without requiring direct integration between AVP and AVC systems.
2Productivity
If AVP and AVC processes run simultaneously, then operational efficiency improves, but safety conflicts and resource contention increase
Solution Approach 1:
The main system performs preliminary determination of whether to activate AVP or AVC based on received requests. It pre-assesses the operational state and decides which system should execute first, preventing simultaneous conflicting operations. This preliminary action ensures safe sequential execution while maintaining operational efficiency through optimized scheduling.
3Device complexity
If a single system controls both AVP and AVC, then coordination is simplified, but operational flexibility and independent optimization are reduced
Solution Approach 1:
The main system provides universal coordination capabilities by managing both AVP and AVC operations through a unified request handling interface. It can determine and activate either system based on operational needs, providing multi-functionality at the coordination level while allowing independent optimization of each subsystem.

AI summary
A method for coordinating an execution of an automated charging and/or discharging process of a battery of an at least highly automated motor vehicle. The method includes: a main system receives a request for executing an automated charging and/or discharging process of a battery of an at least highly automated motor vehicle; the main system starts an AVP system in order to guide the motor vehicle in an at least highly automated manner by means of the AVP system to a charging location as part of an AVP process; when the main system receives a message from the AVP system that the AVP process has been terminated, the main system starts an AVC system in order to charge and/or discharge the battery of the motor vehicle parked at the charging location, in an automated manner, using the AVC system as part of an AVC process, according to the request.
