AVL meets the high expectations of discerning
premium manufacturers. With a high level of
expertise, a comprehensive approach, and an
advanced AVL hardware and software toolchain, the
company can make an important contribution to the
time- and cost-effective development and validation
of challenging HP PHEV projects.

powertrain validation much quicker and cheaper.
The number of prototypes required can be
reduced to a minimum, especially as these are

rapid validation, manufacturers can optimize their
products up until shortly before release. With
virtual feature testing in operation 24/7, AVL can
test and validate a maximum spectrum of driving
maneuvers that can be experienced even before
Start of Production (SOP).

Through targeted use of HiL and SiL, AVL can
guarantee reliable and reproducible validation even
with very few prototypes – and while adhering to
tight schedules that can change dynamically at
any time during the process.
AVL’s Added Value
in Powertrain Validation
The Result
In the space of just 14 months*, AVL carried out a full
validation of the hybrid powertrain, thus enabling a global
market release of the Mercedes-AMG S 63 E PERFORMANCE.
As well as validating emissions (including their subsequent
treatment) this also included intelligent data harmonization
for other vehicle variants. By simulating more than 130,000
kilometers via multi-vECU powertrain SiL, a CODž-optimum
operating strategy including e-drive optimization was
achieved.
The creation of a system model was pivotal for rapid and
reliable validation. This served as a single source of truth
for the precise description of architecture, components,
interfaces, functions, and system behavior including the
respective interdependencies. Among other things, AVL used
this to carry out comprehensive virtual feature testing. The
simulation covered almost every possible driving situation. In
contrast to traditional driving tests on the road, this allowed
Totential TroFlems to Fe identified and resolved early on Ɓ Jor
example, for driving situations that were interpreted differently
by individual control units.
Special attention was paid to OBD: AVL made an important
contribution to the development of the overall system in
tLis area Ɓ Jrom defining sTecifications to release testing.
All OBD-relevant control units in the vehicle were checked
and the error-free interaction of the individual systems was
optimized in terms of emissions, range, and consumption.
AVL also found an optimum compromise between the various
cooling requirements of the vehicle, internal combustion
engine, and electric high-voltage system in terms of thermal
management.ɸ
