Overall Network (GVN) Function - GF00.19-P-0001FG
Model 213
up to model year 2021
Overall network, general
The requirements for vehicle electronics, e.g. in the following areas are constantly increasing:
- Vehicle safety
- Comfort
- Communication
- Diagnosis
This requires 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 bus systems are used.
The vehicle electronics are networked using the following bus systems:
- CAN
- Chassis FlexRay
- MOST
- Ethernet
CAN
The CAN is an electrical bus system for the transmission of data via 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 sent digitally via 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
- Reduction of the number of electrical lines
- Improvement of the electromagnetic compatibility
