The Knorr-Bremse Group is the world’s leading manufacturer of braking systems for rail and commercial vehicles. Knorr-Bremse recognized the impending challenges posed by rising complexity and increasing certification requirements early on and collaborated with Fraunhofer IESE in developing a more sustainable reuse approach.

The Knorr-Bremse Group is the world’s leading manufacturer of braking systems for rail and commercial vehicles. As a technological pacesetter, the company has been a key agent in driving the development, production, sales, and service of modern braking systems for over a hundred years. Knorr-Bremse Systeme für Schienenfahrzeuge GmbH produces innovative pneumatic braking systems for rail vehicles in its business area, and is very successful in this area on the market. Due to different usage scenarios, customer wishes, and regulatory requirements, the braking systems are customized individually to each rail vehicle.
The functions of a braking system are strongly interconnected and at the same time realized in various disciplines. A generic system model was therefore developed in SysML/UML, which describes the functions down to the level of the technical realizations. The system model helps the project members use the available function components efficiently and effectively. A feature model is used to accurately describe adaptation possibilities in the system model. It allows automatic adaptation of requirements, design, implementation, and quality assurance artifacts throughout the model. After the sustainability of the approach has been demonstrated based on the first function components, the approach is rolled out broadly to further functions in the next step.
This is what Robert Seitz, Knorr-Bremse Systeme für Schienenfahrzeuge GmbH, System Functions & Architectures, CoC Brake Control, has to say:
