BDC Body Domain Controller

The body domain controller (BDC) is the central control unit in the body electronics. The Body Domain Controller is installed in the passenger's side footwell. The central gateway module (ZGM) is a virtual independent module integrated in the Body Domain Controller (BDC).

The Body Domain Controller (BDC) is a newly developed control unit with many integrated functions. The aim is to reduce the number of control units and improve component networking. At the same time, the optimization of the wiring harness reduces the physical bus capacity.

The task of the central gateway module (ZGM) is to connect all bus systems. This combination allows general use of information from the individual bus systems. The central gateway module (ZGM) is able to implement various reports and speeds on other bus systems. The programming data are transferred to the vehicle by Ethernet via the central gateway module (ZGM).
