AUTOSAR for Local Interconnect Network Management in Basic Software Modules

The AUTOSAR(Automotive Open System Architecture) is open and standardized automotive software architecture. Developed by automobile manufacturers, suppliers and tool developers. Its is an alliance of OEM manufacturers and Tier 1 automotive suppliers working together to develop and establish a de-facto open industry standard for automotive E/E architecture which will serve as a basic infrastructure for the management of functions within both future applications and standard software modules. AUTOSAR supports the re-use of software and hardware components of automotive electronic systems. In this paper gives Autosar layered architecture, and LINNM overview. Major LIN applications are some integration equipment such as, Door’s, steerin wheel, seats and airconditoning. The AUTOSAR LinNm Module is the hardware independent protocol that can only be used on LIN. The LinNm function provides an adaptation between Generic Network Management Interface (Nm) and LIN Interface (LinIf) module. Its main purpose is to coordinate the transition between normal operation and bus-sleep mode of the network.
