Buses And Control Units In The E70

The important buses in the E70 are called: K-CAN, MOST, PT-CAN, F-CAN, FlexRay.

FlexRay is a new communication system that offers extremely efficient, real time data transfer between the electrical and mechatronic components in the vehicle. FlexRay has a data transfer rate of 10 MBit/s.

FlexRay is used for data exchange between the VDM control unit and the shock absorber satellites.

CHAMP: On the US national version, instead of the multi-audio system controller (M-ASK), the Central Headset And Multimedia Platform (CHAMP) operates as the BMW "Professional" radio. In contrast to M-ASK, CHAMP does not  have a navigation system.
