Overall network (GVN) function - GF00.19-P-0001LE
MODEL 216.3, 221.0 /1 as of model year 2009/YoM 08
General overall network
The heightened requirements placed on vehicle electronics, e.g. in the following areas:
- Vehicle safety
- Comfort
- Communication
- Diagnosis
require networking of the existing systems in the vehicle so that the necessary information can be exchanged.
This cannot be achieved using conventional data transfer since the amount of installation space is limited and a reduction of the weight of the vehicle is targeted. This is why data bus systems are used.
The vehicle electronics are networked using the following data bus systems:
- Controller Area Network (CAN)
- Media Oriented System Transport (MOST)
CAN
The CAN is an electrical bus system for the transmission of data on two lines.
The CAN consists of a twisted two-core data line that connects all CAN participants (control units) via a parallel connection. The two lines of the data line must not be swapped (low level/high level). Each connected control unit is able to transmit or receive data (bidirectional bus).
The data is transmitted digitally on the CAN at various intervals.
The individual data blocks are defined in a data protocol and it is specified which data are received or transmitted by a control unit.
The sum of the data blocks, the short break between two transmission intervals and other properties of the CAN are checked constantly. Detected faults are stored and placed in the fault memory.
The CAN offers the following advantages:
- Data exchange between individual control units
- Provision of sensor signals for several systems
- Reduces number of electrical lines
- Improved electromagnetic compatibility (EMC)
The following CAN systems are involved in the overall network:
- Telematics CAN (CAN A)
- Interior CAN (CAN B)
- Drive train CAN (CAN C)
- Diagnostic CAN (CAN D)
- Chassis CAN (CAN E)
- Central CAN (CAN F)
- Front end CAN (CAN G)
- Vehicle dynamics CAN (CAN H)
- Drive train sensor CAN (CAN I)
- Sensor CAN (CAN S)
