<div class="section abstract"><div class="htmlview paragraph">Due to increase in complexity of vehicle functionality and involvement of electronic components, the use of complex electronic control units is prevalent in today’s vehicles. This has led to increased amount of Electronic Control Unit (ECU) data, and in turn increased Diagnostic data. This Diagnostic data is described in the Automotive Open System Architecture Diagnostic Exchange Template (AUTOSAR DEXT), which is a standard diagnostic data format specified in AUTOSAR 4.2.1 for Unified Diagnostic Services and fault memory. It enables consistent exchange of Diagnostic information across Original Equipment manufacturer OEMs and between OEM and Suppliers, thereby aiding uniformity in configuration of basic software modules described in Automotive Open System Architecture (AUTOSAR) Layered Architecture across enterprise boundaries. DEXT provides the possibility to describe the data to be transported, using respective protocol, along with origin of data in ECU’s application software. When there is availability of both information and data, the configuration of diagnostic basic software becomes possible. This Paper explains the steps which are necessary to process diagnostic data which is being populated in DEXT file, and further tailor it for a production ECU.</div><div class="htmlview paragraph"><i>Index Terms</i></div><div class="htmlview paragraph">—Automotive Open System Architecture, Autosar Extensiable markup language, Basic Software, Controller Area Network, Communication Manager, Diagnostic Communication Manager, Diagnostic Event Manager, Diagnostic Extract Template, Diagnostic Data Identifier, Diagnostic Trouble Code, Electronic Unit Control, Function Inhibition Manager, Local Interconnect Network, Onboard Diagnostics, Open Diagnostic Extract, Original Equipment Manager, Diagnostic Extract Template, Electronic Control Unit, Original Equipment Manufacturer, Unified Diagnostic Services.</div></div>

During embedded software development of complex control system, the calibration is an important approach to obtain optimal parameters of embedded software. Currently, typical calibration systems are with poor adaptability for various controllers which have different communication interfaces and calibration protocols. In order to solve the problem, an improved architecture for embedded controller calibration system is proposed to support more communication buses and protocols. In this architecture, by introducing OPC (OLE for Process Control) technology, the host software of calibration system is separated into OPC server and client. The OPC server masks the difference of various calibration protocols and detail of communication devices, and provides a unified access interface for controller parameters. The OPC client calibrates and acquires the parameters though calling the interface provided by the OPC server. By the method, when communication device or calibration protocol is varied, only the corresponding OPC server is required to be replaced. Then the details of communication devices and calibration protocols are no longer considered while developing a calibration system, and the generality and openness of the calibration system are enhanced greatly. The calibration system corresponding to the architecture was applied to an engine controller to verify the effectiveness of the method presented.
