Bus system analysis: Notes

The electronic control units in the vehicle are connected to one another via a network. In this system network, the central gateway module plays a decisive role. The central gateway module is responsible for ensuring that information is transferred from one bus system to another bus system.

The engine control system and chassis control system are linked via the PT CAN (or PT CAN2) and the FlexRay bus system to the ZGM. The control units of the general vehicle electrical system are connected via the K CAN and the K CAN2.

For most control units in the area of information and communication technology, the MOST is available as an information carrier. The vehicle diagnosis communicates across the D CAN. The vehicle is programmed/encoded via the Ethernet access. The overall network consists of various bus systems that ensure communication between the individual control units.
