Autonomous Vehicle Engineering - September 2021 - 7

Cover Story
Another important feature is a
" fail operational window " that can
be different for different actuation
systems. " A general best practice could
be to report the validated time that is
available for the virtual driver to bring
the vehicle to a safe stop when fail
operation is initiated by a particular
actuation system, " Pandy noted. " This
information can be used by other actuation
systems, or it could be used for
compliance purposes to ensure that
the vehicle was indeed brought to a
safe state within the fail-operational
window that was provided. "
Over-the-air
troubleshooting
during the early stages of development
and integration work also is key.
" A master diagnostic message that
consolidates the status of a fail-operational
system, including the fault
codes, fail-operational time window,
and performance measures, can help
other subsystems to plan for safe
actions as well as roadside inspections, "
Pandy said. " This can be similar
to the existing diagnostic message, but
it is tailored for AVs such that it can be
easily integrated with the V2V or V2I
[vehicle-to-vehicle or vehicle-to-infrastructure]
communications. "
Release testing and
homologation
A sequence of testing - from modelin-the-loop
(MIL), software-in-theloop
(SIL), component, domain and
vehicle hardware-in-the-loop (HIL)
and finally real-vehicle testing - is
necessary to achieve the software
quality and robustness required for
ADAS and AV systems.
" It's about running a lot of tests and
finding the critical edge cases that you
need to validate the software that needs
to be deployed, " said Jace Allen, director
of ADAS/AD Engineering and Business
Development for dSPACE, Inc. " Integral
to all of this is really trying to get a truck
to certification or homologation. "
dSPACE participates with different
organizations including ISO and
collaborates with companies such as
TÜV to offer broad expertise from
system requirements to release testing
and homologation. The company also
expanded its partnership with BTC
Embedded Systems to offer a new
web-based solution, SIMPHERA, that
uses simulation to validate and homologate
autonomous-driving systems.
Available for use in general
customer projects starting second half
of 2021, the SIMPHERA simulation
and validation environment integrates
the BTC ScenarioPlatform that creates
scenarios and generates and evaluates
