(Advanced Driver Assistance Systems)

The DEWETRON ADAS series instruments are made for any
dynamic test of vehicles where precise position information
is required. All dynamic movements such as acceleration,
speed, position, turning speed and angle of the vehicle are
measured synchronously to analog sensors, counters, CAN
bus and video data.
There are a lot of applications such as ADAS (Advanced
Driver Assistance System) testing, LDW (Lane Departure
Warning), functional safety testing, etc. where very accurate
position information (down to 2 cm possible!) is needed.

Key Features
t Precise position, angle, distance, speed
and heading information is recorded fully
synchronized together with analog, counter,
CAN bus and video data
t High accurate combined GPS and Gyro
measurement
t INS/GPS system from GeneSys for six tt
t degree of freedom motion analysis

t
One typical application is to test longitudinal control systems
such as ACC (Adaptive Cruise Control). These measurements are usually performed with two or more vehicles. Each
vehicle is equipped with a DEWETRON ADAS instrument
and a GeneSys ADMA GPS/INS system. The communication
link between each vehicle is WLAN. The DEWETRON data
acquisition unit synchronously records the CAN data from
the ADMA GPS/INS system and vehicles, together with data
from optional digital and analog sensors and video images
of the driver.

t High performance differential GPS position tt

t GPS synchronized measurements from 2
vehicles with online data transfer
t Easy mounting, setup, alignment and
calibration
t Comparable and reproducible tests
t Automated report generation for predefined
maneuvers

t Safe investment, all systems can grow with
The key parameters for testing longitudinal control systems
future applications
such as ACC include the relative position, the relative velocity and the relative heading between the leading car and the
hunting car. (The ACC system to be analyzed is in operation in the hunting car.) There are also further parameters that
are relevant, such as acceleration, velocity, 3D track data, corner radius and the precise time reference. Captured
video data should simultaneously be available to check the driver status as well as the environmental conditions.
Perfect synchronization of data is essential to reach the required accuracies for relative position.
