They enable quick access to modeling, serve as a reference for new technologies,
and create a virtual test environment for the development of new individual
components. Validated vehicle models can be used for a range of applications –
but what exactly are they?
hen validated vehicle models are discussed at AVL
the reference is to system simulation models that
are based on real, commercially available vehicles.
Although they are primarily intended to illustrate all the
functional aspects of a vehicle, these models are based on
physical principles.
Validated models like this can be used in a number of
ways, depending on the target customer: OEMs use them
primarily to benchmark their new developments with other
commercially available vehicles. However, suppliers mainly
use validated models as a virtual environment for new
components and subsystems that they have developed.
They can use the models to test their innovations under
realistic conditions. They can also clearly visualize potential
improvements for the new components.
To create validated models, AVL uses real vehicles that
are currently on the market. These vehicles are procured
as part of the AVL Benchmark program and are subjected
to several measurement and analysis steps. This includes
measuring the entire vehicle and the individual components.
The measurement data is then used to create detailed

The AVL database currently includes more than 300 validated
models of vehicles with a range of drive concepts – from
conventional internal combustion engines to hybrid concepts
and battery-powered and fuel-cell-driven vehicles. For
example, there are validated AVL models of the Porsche
Taycan, the Toyota Mirai II, the Toyota Yaris Hybrid, the
Hyundai IONIQ 5, the Tesla Models 3 and Y, and many more
vehicles. The database is being updated continuously and
sTecific models can Fe created on reUYest at any time.ɸ
