dSPACE NEWS Model-based Development T ool Chain at Volvo Cars In the development of electronic control units (ECUs) for automatic transmission, Volvo Cars has for the first time used a model-based development concept to develop gearshift strategies, and interlinked the subsequent development steps. The Challenge: Linking Development Steps After an ECU’s functions have been described as ei- ther a written specification or a block diagram, they have to be put into executable code as fast as pos- sible. One important objective is to connect the de- velopment steps seamlessly. For example, it is very helpful to developers if they can transfer specifica- tion data from the model design straight to the prototyping process or to production code genera- tion. Development tools that guarantee the r
