Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle diagnostic systems face challenges in protocol conversion between the communication interface of a vehicle and a communication terminal, and the web server, requiring high performance from the communication terminal to handle protocol conversions between different communication protocols.
Innovation Solution
A protocol conversion device and system that includes a converter and communicator to convert vehicle data from a first protocol to HTTP or HTTPS, enabling seamless communication between the vehicle, communication terminal, and web server, thereby eliminating the need for high-performance protocol conversion capabilities in the communication terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication terminal performs protocol conversion between first protocol and HTTP/HTTPS, then protocol compatibility is improved, but the processing load and performance requirements of the communication terminal increase
Solution Approach 1:
The patent introduces a protocol conversion device as an intermediary component between the vehicle (using first protocol) and the communication terminal (using HTTP/HTTPS). This mediator performs the protocol conversion function, allowing the communication terminal to operate with simpler protocols while maintaining compatibility with the vehicle's communication system. The conversion device acts as a bridge that translates between the two protocol formats without requiring the terminal to handle complex protocol conversion logic.
2Adaptability or versatility
If the communication terminal handles protocol conversion, then protocol compatibility is improved, but the cost and performance requirements of the communication terminal increase
Solution Approach 1:
The protocol conversion device serves as a separate intermediary component that handles protocol translation between the vehicle's first protocol and HTTP/HTTPS. This allows the communication terminal to be manufactured with simpler, lower-cost specifications since it does not need to incorporate expensive protocol conversion capabilities. The conversion function is externalized to a dedicated device, reducing the terminal's hardware and software complexity requirements.
3Adaptability or versatility
If vehicle data is transmitted through protocol conversion at the terminal, then web server integration is improved, but the processing time and efficiency are reduced
Solution Approach 1:
The protocol conversion device performs protocol translation in advance, converting vehicle data from the first protocol to HTTP/HTTPS format before transmission to the communication terminal. This preliminary conversion action ensures that the terminal receives data in the correct format immediately, eliminating the need for the terminal to perform time-consuming protocol conversion during operation. The conversion is prepared beforehand, streamlining the overall data transmission and processing workflow.

AI summary
A protocol conversion device includes a converter and a communicator. The converter makes a protocol conversion of vehicle data acquired from a vehicle by communication based on a first protocol, into vehicle data in a format of HTTP or HTTPS as a second protocol. The vehicle data is directed to diagnosis of the vehicle. The communicator transmits the vehicle data protocol-converted by the converter, to a communication terminal that is able to execute, by communication based on the second protocol, a vehicle diagnosis program held by a web server. The converter makes a protocol conversion of data transmitted from the communication terminal by the communication based on the second protocol, into data in a first protocol format. The communicator transmits, to the vehicle by the communication based on the first protocol, the data in the first protocol format that is protocol-converted by the converter.
