Autosar advances with triumph of Mentor-Volvo project

The announcement (June 18) of the success of the Autosar demonstrator project of Mentor Graphics Corp. and Volvo Trucks is driving forward the adoption of the standard in commercial vehicles.

The Metor-Volvo project entailed redeveloping an existing climate control system using the Autosar technology. Mentor was responsible for the development and integration of the software. A key element, according to Mentor, in the development of the tool for the project was the adaptation of Vehicle Network Architect (VNA) into the design flow. Meanwhile, Live Devices of ETAS Group was tapped for the development of the OS and the run-time environment generator.

Five months after the start of the project, a prototype was integrated and tested in a truck. "The prototype included support commercial vehicle-specific bus protocols such as SAE J1587 as well as advanced control of actuators such as stepper motors," said Joakim Ohlsson, senior software architect, Volvo 3P, in a statement. "The application was also split in different wars over ECUs [electronic control units] to test the transferability of functions across the network."

Gaining ground
Results from the demonstrator project indicate that the major Autosar concepts are working; it is possible to handle special needs for commercial vehicles; and, Autosar components and tools are mature enough to start concept studies targeting product development.

These developments, according to Antal Ranjak, Mentor's chief scientist, automotive programs, system level engineering division, will step up further interest in Autosar. "There is increasing interest [in the Autosar standard] in Japan and in the United States," revealed Ranjak, during a meeting with Asian editors last week in Campbell, California. In fact, carmaker Chrysler, said Ranjak, "has perceived the standard as stable." Interest is also increasing in China, particularly on the software development front.

Mentor is a premium member of the Autosar consortium, which is working to create an open standard for automotive engineering architecture. Autosar released its first set of specifications (release 2.1, January 2007) to be used as the basis for product development.
