Small, compact and unique worldwide:
A new generation of ADMA gyro systems for measuring
the vehicle dynamics with an output rate of 1000 Hz
For more than a decade, GeneSys Elektronik GmbH in Offenburg
has produced a GPS-aided gyro system named Automotive
Dynamic Motion Analyzer, ADMA in short. It is developed and
produced specially for measurements of vehicle dynamics and
driver assistance parameters in the automotive sector. With a
significantly
enhanced
computing
performance,
interface
extensions and an improved real-time capability, the new
generation
of
ADMA
meets
customers'
needs
worldwide.
Achievable previously was a maximum output rate of 400 Hz with
limited data records. ADMA 3.0 now allows an output rate of 1000
Hz with unlimited data records and a data latency of less than 1
millisecond! Besides CAN-bus interfaces, the device now includes
new Ethernet interfaces for data output, configuration and
updating. Measurement data are available for an evaluation in real
time, enabling a user access at very high data rates.
Driver assistance systems are becoming increasingly significant in
automotive engineering, due to their ability to further enhance the safety
and comfort of modern vehicles. When measuring the vehicle dynamics
in the automotive sector, the accurate determination of all movements is
an important requirement for it. The ADMA permits a high-precision
dynamic measurement of all states of motion such as acceleration,
velocity, position, rotational speed, position angle and slip angle of the
vehicle. GeneSys Elektronik GmbH developed the first ADMA
(Automotive Dynamic Motion Analyzer) gyro system specially for such
applications already more than a decade ago.

With the new ADMA 3.0 generation, the data output rate has been
increased to 1000 Hz by using a very fast signal processor and a
modern FPGA. A total of 3 Ethernet and 5 CAN-bus interfaces allow a
rapid data transfer, the various Ethernet interfaces serving for data
output, configuration and updates.
In practice, such high data rates in real time prove particularly valuable
in developing driver assistance systems. For example, the position of a
vehicle moving at 100 km/h can be resolved to less than 3 cm. Thus,
many new possible applications with even more accurate results can be
realized.
Another positive feature in addition to the extremely high sampling rate
is the ability to transmit GPS correction data via Ethernet. In the case of
distance measurements previously, for instance, it was necessary to
equip each participating vehicle with a receiver for DGPS correction
data. With the latest generation of ADMA, it suffices to simply link the
target vehicle to the correction data service. All other vehicles can be
connected free-of-charge via WLAN to the target vehicle. This saves
time and additional connection costs.
An enhanced computing power with a very fast DSP in conjunction with
a modern FPGA permits relative data calculations directly inside the
newly developed ADMA. The target vehicle sends its position data to
the following Ego vehicle via WLAN. The calculations of the distance,
the relative speed and the position angle with respect to the Ego vehicle
still take place inside the ADMA 3.0, the data being made available
online right away. Besides serving for the classical data output, the
Ethernet interface is also a convenient and simple means of

autonomous vehicle guidance is still possible.
