Overview
Fragrance diffuser system

Air ionization system

As with the 2019 A8, the fragrance diffuser system with
two different fragrance types is offered for the Audi A7. The
fragrances are kept in cylindrical vials in Fragrance Diffuser
System Functional Unit GX43. A small blower distributes
the fragrance from the vial into the outer front air outlets.
In addition to the fragrance type, four levels of intensity
can be selected.

An air ionization system is used to improve the air quality.
The air ionization system works by negatively charging air
particles to a limited extent. They are distributed in the
vehicle interior via the side and front air outlets. These
negatively charged ions attract dust and similar very small
particles. As a result, the air in the vehicle interior is
cleaner.

Controls in front of vehicle
The climate control system of the 2019 A7 is managed by
Vehicle Electrical System Control Module J519. Therefore,
Climate Control Module J255 is not installed in the vehicle.
Communication between J519 and the climate control
components is done via a LIN bus system.

Driver assist systems
Introduction
This topic includes short descriptions of the five most
important innovations in the 2019 Audi A7. All of these
innovations made their début in the 2019 Audi A8. The
innovations concern new hardware which continues to pave
the way for autonomous driving, a new and innovative
operating concept and new driver assist systems.

Further information on all the new features can be found
on the following pages and more detailed information is
available in eSelf-Study Program 990393, The 2019 Audi
A8 Driver Assistance Systems.

Driver assist system innovations in the 2019 Audi A7
Driver Assistance Systems Control Module J1121

Laser Distance Regulation Control Module J1122

J1121 is the first step toward reducing the number of
control modules for driver assist systems. With and eye on
the major vision of autonomous driving, Audi is gradually
moving away from a decentralized approach of several
individual control modules to an approach with a powerful
central computer. There are four versions of J1121 for the
2019 A7. The version installed depends on the driver assist
systems in the vehicle.

Laser Distance Regulation Control Module J1122 is a combination radar sensor and laser scanner. It replaces the two
long range radar sensors that previously implemented the
longitudinal regulation functions of adaptive cruise assist.

Profile master for driver assist systems
The profile master is a new operating concept that specifies
the activation conditions for the different driver assist
systems. A total of eight driver assist systems participate in
the profile master system. The customer can choose
between three profiles: maximum, individual and basic. The
maximum setting switches all participating systems on.
With the individual setting, the customer decides which
systems to activate and with basic, a maximum of two
permanently specified systems are switched on.

Lane departure warning and adaptive cruise assist

The laser scanner is installed at the front of the vehicle, has
a scanning angle of approximately 145 degrees and can
detect objects up to approximately 262 ft (80 m). A significant strength of the laser scanner is that its measurement
precision is not dependent on the distance of the target
object.

Intersection assist
The intersection assist helps the driver to avoid collisions
with road users crossing the vehicle’s path. The intersection
assist works between speeds of 0 to 19 mph (0 to 30
km/h). However, a brake application is only made at speeds
of up to 6 mph (10 km/h). The intersection assist is very
similar to the rear cross-traffic assist. The main difference
is that the intersection assist performs its task in front of
and not behind the vehicle.

ACC and Active lane assist “early” comprise a new system
called Adaptive cruise assist.
The lane departure warning warns the driver if there is a
risk of inadvertently leaving the current lane. However, the
adaptive cruise assist offers the customer combined longitudinal and lateral guidance for the vehicle at speeds
between 0 to 155 mph (0 to 250 km/h).

79

Driver Assistance Systems Control Module J1121
Introduction
The 2019 Audi A7 will have a J1121 control module. This is
because Audi pre sense front, which requires J1121 for its
functions, has been specified as standard equipment .
Driver Assistance Systems Control Module J1121 is now the
master control module for all driver assist systems for
which calculations were previously performed by Driver
Assistance Systems Front Camera R242.
The front camera still captures the area in front the vehicle.
However, the images from the camera are processed by
J1121.

J1121 has taken over the following functions:
>> High beam assist.
>> Camera-based traffic sign recognition.
>> Lateral vehicle guidance (lane departure warning and lane
guidance by the adaptive cruise assist).
>> Emergency assist.

It remains the master control module for the following
driver assist systems:
>> Surround view cameras (Peripheral Camera Control Module J928
is no longer installed).
>> Intersection assist (introduced in the 2019 Audi A8).

669_091

Driver Assistance Systems Control Module J1121 has
another designated name. The second designation is zFAS
control module. This comes from technical development
and has established itself in general usage. zFAS is the

80

abbreviation of the German term for "driver assist systems
central control unit" (zentrales Steuergerät für
Fahrerassistenz­system).

Versions of the J1121
Four versions of J1121 are available. The version installed
depends on which driver assist systems are chosen by the
customer when the vehicle is ordered.

Control module version A/A0

The J1121 in the 2019 Audi A7 has the same part number
as that of the 2019 Audi A8: 4N0.907.107. The versions
can only be differentiated by the index letters following the
part number.

Control module version C/D

669_093

All location table for driver assist systems — Control module version
The following table shows which version of the control
module is required (at least) by the different driver assist
systems. The lowest version of the control unit is A0, the
highest at the launch of the Audi A7 is version C. The higher
versions are always backward-compatible, meaning that,
version C is also suitable for all assist systems with an X in
the columns for A0, A and B.

The following table includes a fifth version of J1121. This is
version D, which also includes the software for the traffic
jam pilot. The traffic jam pilot will be introduced at a later
date.
