Service-Specific Parameters for DEbag
When driving in Germany, the following parameters must be manually updated on the On-Board Unit (OBU) based on your current vehicle configuration:
- Trailer Axles
Update the number of trailer axles whenever your trailer configuration changes. This directly impacts toll calculations.
- Gross Train Weight (GTW)
The GTW is the maximum permissible weight of both the tractor unit and the attached trailer. This must be updated each time a trailer is connected.
Example display on OBU: selecting a weight range such as “≥7.5t and <12t” will show the lower value on the screen (7.5t).
- Axle Configuration
Ensure the total number of axles (tractor + trailer) is correctly shown. Trailer axles must be configured separately via the OBU.
- CO₂ Emission Class
Enter the correct CO₂ class (1–5) as per Directive 1999/62/EC, Article 7ga.
If unknown, the system defaults to class 0, and toll charges will be calculated at the most expensive rate (class 1).
Please make sure you are regularly updating these values to maintain compliance and avoid unnecessary toll charges.
