Developing modern driver assistance systems
involves an ever-growing amount of data which
must be processed in real time. Hyundai MOBIS
uses a HIL setup that is based on dSPACE
SCALEXIO and can develop and test multiple
driver assistance systems at the same time.
means that it must be possible to
simulate the various driving situa-
tions realistically and reproducibly
on a test bench under defined con-
ditions. This task is becoming more
complex because many driver assis-
tance functions involve combining
and evaluating measurement data
from different environment sensors
in real time. One of many examples
is automatic emergency braking.
In this example, first the cameras
visually detect the road users, while
the radar measures the distances
and velocities of these traffic partici-
pants. On the basis of this overall
picture, the vehicle computer can
then decide whether emergency
braking is required and calculate
the appropriate instructions for the
brakes. This combining of measure-
ment data from different sensors in
a split second, also called sensor
fusion, is one of the biggest chal-
lenges when developing the driver
assistance systems of tomorrow.
Six in One Blow
Besides automatic emergency brak-
ing, there are many other situations
in which several driver assistance
systems need to interact with each
other. In the first step, Hyundai
MOBIS is using a SCALEXIO
®
HIL
simulator to test a total of six driver
assistance functions:
Parking assistance system (SPAS =
Smart Parking Assist System)
Lane departure warning system
(LKAS = Lane Keeping Assist System)
Automatic proximity control
(SCC = Smart Cruise Control)
Emergency braking (AEB = Auto-
nomous Emergency Braking)
Assisted steering (MDPS = Motor
Driven Power Steering)
Electronic stability control (ESC =
Electronic Stability Control)
Realistic Driving in the Lab
The central elements of the setup
are a dSPACE SCALEXIO HIL simula-
tor equipped with simulation mod-
els from dSPACE, and 3-D online
animation via dSPACE MotionDesk
to visualize the driving maneuvers.
This development environment is
connected to multiple test benches
for various driver assistance systems
(figure 2). There is one test bench
for the radar scan of the vehicle
environment, one for camera-based
