AUTOSAR is finding its way into the automotive industry. European automotive manufacturing companies were the early adopters defining and promoting AUTOSAR standard. One of the main AUTOSAR goals is to improve containment of product and process complexity and risk. Increased scalability and flexibility to integrate and transfer functions is another important goal of AUTOSAR. Working with different suppliers and vendors and respect their confidentiality makes the process of application software development even more complex. Presented in this paper is a creative way of utilizing AUTOSAR to overcome the integration challenges in a multi-party object code based software integration. The run time environment (RTE) files for the application software are generated through a set of scripts to automate the process for consecutive releases. The low level device drivers are configured by one supplier and are being used by another supplier through a set of AUTOSAR client-server operation calls.

The heavy-duty diesel industry continues to expand the use of sophisticated electronic controls to reduce greenhouse gas emissions and improve fuel economy in the transportation sector. This inevitably leads to a need for increased knowhow in all aspects of embedded software development, e.g. in writing model-based specifications, rapid controls prototyping, automatic code generation, and hardware-in-the-loop (HiL) testing. In addition, the software development organization has to recognize the need to establish maturity in its verification and validation test framework, which includes, among other things, a proper definition of testing process and workflow, greater organizational focus, and a robust tool architecture for software testing. Navistar has already undertaken a model-based approach to software development and continues to improve their processes, technology, and tooling in this area.
