The operational fields of the listed systems are distributed as follows.
- Class B data bus (CAN B) links comfort and lighting control units (e.g. power windows, heated windows, exterior and interior lighting).
- Class C data bus (CAN with) links the control units of the engine, transmission, brakes and stability control systems.
- Digital data bus (D2B) via fiber optic cable provides communication of navigation and communication tools.
These information networks place high demands on electromagnetic compatibility and data transmission speed.
