Implementation of DCM module for AUTOSAR Version 4.0

چکیده
Standardization is very much the trend in the development of automotive electronics. The use of open architectures and configurable components are intended to let developers focus more on the innovative and differentiating aspects of the development process. AUTOSAR (AUTomotive Open System ARchitecture) has the stated goal of standardizing a common open automotive software architecture. It is a standard platform for vehicle software. The components in AUTOSAR are hardware independent. The diagnostic stack in AUTOSAR consists of three modules: DCM, DEM and FIM. The DCM (Diagnostic Communication Manager) implements the diagnostic communication per ISO 14229-1. This paper focuses on the design and development of the DCM module for AUTOSAR 4.0. The Diagnostic Communication Manager (DCM) provides a common API for diagnostic services in the AUTOSAR-Basic Software. DCM checks if the diagnostic services request is supported and if the service may be executed in the current session according to the diagnostic states.
