Profile master for driver assist systems
Some of the driver assist systems offered in the Audi A7
can be switched on and off in the profile master for driver
assist systems. Other driver assist systems which the driver
switches on and off specifically while the vehicle is moving
continue to use the classic controls. These include, for
example, the parking aid and the adaptive cruise assist.

Audi side assist
Description of function
The lane departure warning on the Audi A7 is an independent system. This function was previously known as Audi
active lane assist with the steering input set to "late".
The lane departure warning warns the driver if the vehicle
is at risk of leaving its current lane when the corresponding
turn signal has not been activated. If the turn signal is not
activated, the system assumes that the driver does not
intend to leave the lane.

The lane departure warning can be given in three different
ways:
>> By steering input from the system towards the middle of the
lane.
>> By a steering wheel vibration (this warning can be switched off
on the MMI).
>> By coloring the lane demarcation line red in the function displays.

The lane departure warning is switched on and off on the
lower touch display. If the lane departure warning is
switched off, it can be seen as a red bar above the function’s
symbol. If the lane departure warning is switched off, it only
applies for one Terminal 15 cycle. It is active again the next
time the ignition is switched on, regardless of whether it was
on or off when the ignition was switched off.

Master control module
The master control module for the lane departure warning
is Driver Assistance Systems Control Module J1121. Version
A0 of J1121 is sufficient for this function.

Note
The steering assist button on the end of the turn signal lever is not relevant to the lane departure warning. It is only used to
activate and deactivate the lane guidance system of the adaptive cruise assist.
84

Adaptive cruise assist
Description of function
Adaptive cruise assist offers combined longitudinal and
lateral guidance at speeds between 0 to 155 mph (0 to
250 km/h). Longitudinal guidance refers to accelerating
and braking and lateral guidance refers to steering the
vehicle. Because the longitudinal and lateral guidance has
been merged in the adaptive cruise assist, the driver assist
systems "Audi adaptive cruise control (ACC)" and "Audi
active lane assist (AALA)" can not be ordered for the 2019
Audi A7.

The function of the Audi active lane assist with "early"
steering input, the so-called "lane guidance", has been
integrated into the adaptive cruise assist. The section with
"late" steering input has become an independent system
with the new designation "lane departure warning".
The lane guidance can be switched off on the adaptive
cruise assist so that only longitudinal guidance remains
active. If lane guidance is switched off, the vehicle behaves
as it would previously have done when driving with adaptive
cruise control. However, it is not possible to deactivate
longitudinal guidance on the adaptive cruise assist when
lane guidance is active at the same time.

Restructuring of the longitudinal and side regulating
systems
Audi has fundamentally restructured the functions of the
Audi adaptive cruise control and the Audi active lane assist
for the introduction of the new Audi C and D segment
models. This has created the lane departure warning and
the adaptive cruise assist. This restructuring is shown by
the diagram below. It is a comparison of the systems in the
Audi Q7 and Audi A4/A5 with those in the Audi A8 and
Audi A6/A7 .

Displays and operation
There have been changes to the function symbols and
displays for the vehicle side guidance systems. If lane
guidance is active in the adaptive cruise assist, this is

shown by green triangles on the left and right of the
vehicle. If two white triangles appear, lane guidance is
switched on but not active. If no triangles are visible, lane
guidance is switched off.

The adaptive cruise assist is activated via the operating
lever previously used for ACC. This operating lever can be
used to set the desired speed and distance, as with ACC.

The steering assist button on the end of the turn signal
lever is only used to switch lane guidance on and off. The
lane departure warning has its own on/off button. This is
located in the virtual row of buttons on the lower touch
display.

Hardware and sensors
Both a long range radar sensor and a laser scanner are
installed on the Audi A7 to implement the longitudinal
regulation functions of the adaptive cruise assist.

Combining the strengths of two types of sensor means that
the longitudinal regulation functions perform better than
they would if two sensors of the same type were used.

Master control module
The master control module for the adaptive cruise assist
function is Control Module for Adaptive Cruise
Control J428. However, the adaptive cruise assist’s basic
functions (longitudinal and side regulating function) are

86

implemented by different control modules. The master for
longitudinal regulation functions is Control Module for
Adaptive Cruise Control J428 and the master for side regulation functions is Driver Assistance Systems Control
Module J1121.

The layout and functions of Right Adaptive Cruise Control
Sensor and Control Module for Adaptive Cruise Control
J428 correspond to those of the 2019 A8. Even though the
locations are different than those of the A8, the adjustment process is not affected. For aesthetic reasons, the
sensor has a trim cover similar to the randome of the laser
scanner.

Laser Distance Regulation Control Module J1122
Laser Distance Regulation Control Module J1122 is
installed on the right side of the grill next to the Audi rings
and symmetrical to the radar sensor. There are no significant differences to the layout and function of the laser
scanner on the 2019 A8. The servicing needs and adjustment process are identical.
The location of the scanner washer jets is new compared to
the 2019 A8.

New lane guidance features
With the introduction of the adaptive cruise assist, the lane
guidance is, for the first time, operational until the vehicle
is stationary. This only applies if all the requirements for
the lane guidance have been met. With Audi active lane
assist, it is only available at 40 mph (65 km/h) and above.
Because of the lowering of the activation speed to zero,
Audi looked for further objects/structures which could also
be used to facilitate a lane guidance system. The Audi
active lane assist only allowed lane guidance on the basis of
road markings.

669_107

The following objects/structures can now be used for lane
guidance at low speeds:
>> An Armco barrier following the course of the road.
>> A transition from the road to the area surrounding the road
which offers sufficient contrast.
>> A curb following the course of the road.
>> Vehicle(s) ahead.

669_108

Roads without a central lane markers
The system still assumes that the road has two lanes if its
width exceeds a defined minimum. If this is assumed, lane
guidance can be implemented on the basis of the detected
right lane marking and a virtual center line. Calculating the
progression of the virtual center line is done by Driver
Assistance Systems Control Module J1121.
As an alternative to the right lane marking, lane guidance
can also, at lower speeds, be performed using one of the
structures specified above.
669_109

New predictive efficiency assist features
A new feature for predictive efficiency has been added to
the 2019 A7. It gives the option for the vehicle’s longitudinal guidance not only to regulate to a speed set by the
driver, but also to adapt that speed automatically to the
speed limits detected by the camera-based traffic sign
recognition system. In addition, it is possible to adjust the
vehicle’s speed for an upcoming corner as well as to reduce
the vehicle’s speed before a traffic circle which will then be
driven through. The focus of the function is a predictive
driving style focused on fuel saving via longitudinal regulation.

88

On the Audi A7, the predictive efficiency assist can also
adjust the speed when the vehicle is approaching an intersection with stop signs and all other requirements for this
have been met. In this case, the system automatically
reduces the vehicle’s speed to 9 mph (15 km/h). Continuing
to brake the vehicle remains the responsibility of the driver.
As with the adaptive cruise assist, the entire predictive
efficiency assist function is a driver assist system. The
driver alone remains responsible for controlling the vehicle
at all times.

Emergency assist
Description of function
The emergency assist is designed for situations in which the
driver is affected by a medical emergency and is therefore
no longer able to drive the vehicle.
The job of the emergency assist in this situation is to
assume longitudinal and lateral guidance of the vehicle and
then to brake the vehicle to a controlled stop in its lane. If
the vehicle is approaching another road user too fast, the
vehicle is braked more forcefully in an attempt to avoid an
impending collision. If a collision can no longer be avoided,
the system attempts to reduce the severity of the collision.
The emergency assist activates itself if the system does not
detect any driver activity in a specified period of time. The
driver activity is established from his/her steering behavior
and the longitudinal guidance the vehicle is receiving:
active acceleration and braking.
When the emergency assist is active, a sequence of measures is set in motion in the vehicle. These have been implemented to protect the driver and to keep the risk of collision as low as possible.
The following measures are initiated during the braking
procedure:
>> Activation of the hazard warning lights to warn other road
users.
>> Full tensioning of the seat belt during the process of braking to
a final standstill.
>> Automatic closure of the windows and the panoramic sunroof.

The second main job of the emergency assist is to take
various measures to attempt to get an inactive driver to
reassume the task of driving the vehicle. It could be the
case that the driver is simply distracted and is no longer
assuming the task of driving the vehicle as a result, even
though he/she would have no problem doing so.
To do this, the system takes the following measures before
and also during the braking procedure:
>>
>>
>>
>>
>>
>>

Display of text notifications in the instrument cluster.
Emitting acoustic signals.
Giving a brake jolt.
Giving a strong emergency brake jolt.
Tensioning the driver's seat belt.
Muting the infotainment system’s audio output.

If the driver is able to reassume the task of driving the
vehicle, he/she can do so in the following ways:
>> Actively taking over the steering again.
-or>> Pressing the brake pedal.
-or>> Pressing the accelerator pedal.

If the emergency assist detects that the driver is once again
active, it deactivates itself and ends its longitudinal and
lateral guidance.
The emergency assist can be activated more than once in
one Terminal 15 cycle.

Once the vehicle has come to a stop, the following measures are initiated.
>>
>>
>>
>>

Transmission position "P" is selected.
Vehicle doors are unlocked.
Interior lighting is switched on.
An emergency call is made.

Intersection assist
Description of function
Intersection assist helps the driver to avoid collisions with
road users crossing the vehicle’s path. These road users can
be normal vehicles, buses or lorries, but also cyclists or
motorbike riders.

If a cyclist or motorbike rider is detected by the system, the
same warnings are given as with a vehicle.

The intersection assist provides assistance in the following
traffic situation:
The red vehicle (equipped with the intersection assist) is
standing at an intersection and wishes to drive straight
across it. To do so, the driver needs to pay attention to the
traffic coming from both the left and right on the main
road. On both sides, the crossing traffic consists of a car
and a bicycle. If the driver of the red vehicle were now to
move off, the intersection assist would activate and would,
depending on the current estimation of the danger level,
warn the driver or apply the brakes.

669_113

Intersection assist works at speeds between 0 and 19 mph
(0 and 15 km/h).
The intersection assist is very similar to the rear cross-traffic assist. It corresponds to a front cross-traffic assist, but
has been renamed to intersection assist.

Sensors

Master control unit

The vehicle requires two additional radar sensors for the
intersection assist. These are located on the front left and
right sides behind the front bumper. The front radar
sensors are very similar to the two rear radar sensors.

The master control module for the intersection assist
function is Driver Assistance Systems Control Module
J1121. A minimum of control module version B is required.

In service, they are referred to as:
>> Control Module for Left Front Object Detection Radar Sensor
J1088.
-and>> Control Module for Right Front Object Detection Radar Sensor
J1089.

Surround view cameras
The surround view cameras are now in their third generation. The first two generations of the surround view
cameras required Peripheral Camera Control Module J928.
The software for the 3rd generation surround view camera
function is now integrated in Driver Assistance Systems
Control Module J1121 along with the software for other
driver assist systems. The surround view cameras require a
J1121 control module of version C.

The data from these ultrasonic sensors can only be read by
J1121 (version C). In this case, J1121 is the master control
module for the surround view cameras and also the parking
system plus.
If the vehicle has the parking system plus but not the
surround view cameras as optional equipment, 5th generation ultrasonic sensors are used. The data from these can
only be read by Vehicle Electrical System Control
Module J519. In this case, J519 is the master control
module for the parking system plus.

All four surround view cameras transmit their images to
J1121 via shielded LVDS wires. J1121 then generates the
vehicle view desired by the customer from the camera
images. The vehicle view is transmitted to Information
Electronics Control Module 1 J794 via two screened LVDS
wiring pairs as a Full HD image. The image is shown on the
upper touch display.
If the vehicle has both the parking system plus and the
surround view cameras as optional equipment, 6th generation ultrasonic sensors are used to meet the requirements
of the surround view camera system.
