Service Proxy Mapping for New Services and Signal Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conversion devices struggle to update conversion maps when new services are introduced and cannot support services that issue operation instructions to signal communication ECUs, leading to potential service limitations.
Innovation Solution
A service proxy device and system that includes a first communicator for service communication, a second communicator for signal communication, a database for mapping functions to services, and a controller to manage and update conversion maps, enabling support for new services and operation instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conversion device uses automatic update based on data similarity, then the conversion map can be updated efficiently, but it cannot support new services without similar data
Solution Approach 1:
The patent introduces a service proxy device as an intermediary between service communication ECUs and signal communication ECUs. This proxy maintains a conversion map that can be manually or automatically updated, allowing it to mediate communication for both existing and new services. The proxy device enables new service support by allowing manual addition of conversion rules without requiring similar historical data, thus resolving the contradiction between update efficiency and new service adaptability.
2Device complexity
If the conversion device only handles data conversion, then the system remains simple, but it cannot support services that issue operation instructions
Solution Approach 1:
The service proxy device is designed with multi-functionality, handling both data conversion and operation instruction forwarding. It maintains a conversion map for data translation between service and signal communication protocols, while also being capable of forwarding operation instructions to signal communication ECUs and relaying their responses. This universal design allows a single device to support diverse communication needs without significantly increasing overall system complexity.
3Adaptability or versatility
If manual updates are implemented for the conversion map, then new services can be supported, but the update process becomes more complex
Solution Approach 1:
The conversion map update mechanism is designed to be dynamic, supporting both manual updates for new services and automatic updates based on data similarity for existing services. The system can adapt the update method based on the service type and available information, making the update process flexible rather than statically complex. This dynamic approach allows manual intervention when necessary while maintaining simplicity through automation when applicable.

AI summary
A service proxy device (20), a service providing system (1), and a service proxy method store a map table in a database (230), wherein the map table associates functions with services and identifies a server (30) having the function and a client (10) requesting the service, receive a service execution instruction requesting execution of the service from the client (10) via a first communicator (210) connected to the client (10) via a first communication, receive an execution result of the function associated with the service from the server (30) via a second communicator (220) connected to the server (30) via a second communication, and transmit the execution result of the function associated with the service to the client (10) via the first communicator (210) based on the service execution instruction and the map table.
