Ready for VECTO: Certified simulation for maximum efficiency

Trucks and buses cause around a quarter of all CO2 emissions from road transport. However, the Paris Agreement stipulated that lorry manufacturers must reduce average CO2 emissions for new commercial vehicles by 15% by 2025 compared to 2019, and by 30% by 2030. To check this, the VECTO simulation tool was developed in 2019. This tool can be used to calculate the fuel consumption and CO2 emissions of commercial vehicles. Lorry manufacturers must now record the VECTO value for each of their vehicles.

VECTO: Vehicle Energy Consumption Calculation Tool

The following data is required to record the VECTO value:

Simulated driving behaviour
Engine power
Rolling resistance of the tyres
Coefficient of drag (cw)

The aerodynamic drag can be determined by means of an experimental constant speed test. However, this method proves to be very time-consuming.

Why act now?

An alternative is to determine the drag coefficient using CFD analysis. However, in order to be able to use the drag coefficients calculated with a CFD analysis in VECTO, the analysis expert must be certified. In order to achieve certification, he must prove the quality of his simulation results by carrying out a comparative simulation himself.

For this purpose, a drag coefficient analysis must be carried out using a basic simulation model provided by the EU. In addition to the original basic model, calculations with add-on parts must also be verified. This involves integrating Tall Rear Flaps (TRF) and Long Side Covers (LSC) into the basic model and simulating the drag coefficient again.
