Experiences from Model Based Development of Drive-By-Wire Control Systems

Paper in proceeding, 2004

Research in distributed dependable control systems within the automotive industry is of high importance today. One reason is the introduction of more mechatronical systems. Volvo Car Corporation and the Royal Institute of Technology initiated a joint project in October 2002 to target this technology change. The project was named FAR, which stands for Function and ARchitecture integration. FAR focused on the development of drive-by-wire systems using model based development. The deliveries from the project were a tool chain for automatic code generation from Matlab Simulink and Matlab Stateflow models and also a prototype vehicle in scale 1:5. It was a very successful project and the result was delivered to Volvo Cars in June 2003. The project deliveries have been further developed at Volvo Cars since then. Primarily, a new hazard analysis method has been developed and new fault tolerance mechanisms have been implemented.
