Data
The development state and quality of the available models
determine which simulation tools are deployed – for example,
AVL CRUISE™ M, or Simulink or even MOTRAN models. AVL
ModelConnect™ links the models from the various simulation
tools with a Digital Twin in co-simulation.
Flexibility with Changing Parameters
Complex projects regularly involve unexpected changes, and
this includes the AVL demonstrator truck. The intended in-
house developed battery was unavailable due to supply chain
issYes. 'Langes enaFled tLe overall veLicle to Fe modified to
allow the use of a commercial battery instead. A simulation
was run to evaluate the effects and compare the battery
originally planned with the new battery in terms of hydrogen
consumption, with several cycles simulated.
AVL used AVL Testbed.CONNECT™ and Model.CONNECT™
to build a HiL system of the demonstrator truck to test its
newly developed control units in a network, from the vehicle
control unit to the e-axle control unit to the fuel cell control
unit. AVL’s control units were available as hardware, while the
output signals and vehicle input data were simulated using
a CruiseM® model and fed into the control units via a further
CAN bus (the HiLSimCAN). This allowed the interaction of the
new components to be tested before the vehicle was built.
On the Road by Beginning of 2025
The demonstrator truck highlights AVL’s skills in the
development of overall vehicles, propulsion systems, and their
integration into the vehicle. We can support our customers
in every phase of their development and have the relevant
e\Tertise, tLe reUYired tools, and sYƾcient testFed caTacity.
AVL’s simulation methodology is pivotal in meeting customer
requirements for CODž reduction, shortened development times,
integration of new technologies, and simultaneous assurance
of the highest quality. The demonstrator truck shows the
potential for use in heavy-duty commercial vehicles, and the
vehicle and its simulation models have been validated by
numerous testbed results. The vehicle will be on the road by
beginning of next year, demonstrating AVL’s visionary solution.
Identifying Solutions
The AVL fuel cell technology demonstrator truck’s
performance will be comparable with today’s standard tractor
units for long-haul transport. However, there are no plans
to mass TrodYce tLe veLicle in tLis configYration. 6atLer,
