Validating Autonomous
Driving Systems

Visteon is participating with 22 partners in
a research project aimed at developing legal,
time-saving, cost-effective validation methods
for fully automated and autonomous driving func-
tions (SAE levels 4 and 5). These driving functions
are expected to play a key role in future mobility
solutions. The aim is to jointly develop a method
for validating driving simulations in order to pro-
duce a reliable test environment. Visteon is sup-
porting this project in a number of areas, including
with its modular, flexible DriveCore solution. The
system is based on an open hardware and software
platform and consists of three elements. With
Compute, Runtime, and Studio, all the require-
ments of the test project can be evaluated in order
to confirm that the simulated validation has been
tested efficiently and the amount of real-life test- © Visteon
ing can be reduced.
