the audi a8 zfas adas platform by aptiv - system plus
TRANSCRIPT
Today’s semi-autonomous cars use a
wide range of sensors (i.e. cameras,
radar, and LiDAR) to assist the driver.
However, the driver must still handle the
actual driving. In order to reach the
conditional autonomy offered at level 3,
it was necessary to bundle sensor-
derived data into a central interface unit
that can combine and interpret the data,
and react without human intervention.
The zFAS control unit, manufactured by
Aptiv (Delphi) in Hungary, is the brain of
the Audi A8’s advanced driver assistance
system (ADAS) platform. zFas combines
multiple computing tasks on a powerful
main board equipped with multiple
microprocessors and a microcontroller.
The included Nvidia Tegra K1 sensor is
dedicated to processing data from the
cameras to create a 360-degree
surround view of the vehicle.
Meanwhile, the Mobileye EyeQ3
processes the more time-critical data
from the stereo front-camera and driver-
monitoring camera. The Intel (Altera)
Cyclone V chip, with an integrated ARM
processor, is used for most of the sensor
data fusion, and the Infineon Tricore chip
is responsible for steering and braking
decisions. Lastly, AT&S supplies the
electronic board, which uses semi-Flex
technology.
Our report, which is based on a
complete teardown analysis of the Audi
A8 zFAS control unit, provides the bill-of-
materials (BOM) and manufacturing cost
of the control unit. The report also
includes a resumed physical analysis of
the main ICs (NVIDIA, Intel, and
Infineon), along with a complete cost
analysis and an estimated sales price.
