Contemporary up-to-date vehicles contain more and more electronic devices. Besides passenger cars, commercial vehicles also have a large number of functions controlled by electronic units, from convenience systems to safety-critical systems. Electronic control units control the engine, the automatic gearbox and the brake system. Through interconnection of such control units in a vehicle such complex systems had been developed which could not be conceived without electronic control units.
Knorr-Bremse is one of the world’s leading manufacturers of braking systems and their control units, having a great experience in automotive development and production. I have written my thesis at the Budapest Research and Development Center of Knorr-Bremse, where I developed a new testing method for fault detection of the electronic control units for brake systems of commercial vehicles.
In my thesis I present this method and its results. After the basic information I describe the difficulties and highlights experienced during the implementation along with the details of integration of the newly developed module into the existing environment. During the development arose alteration suggestions that go beyond the scope of the original task; they are also covered in this thesis.
