Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 106 Instrume nt cluste r : approac h warn ing
Braking guard uses radar sensors and a video
camera. It also functions within the limits of
the system when adapt ive cruise control is
switched off .
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud-
denly or if your own vehicle is traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
guard does not react if it cannot detect the
situation.
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you will
not be able to avoid a collis ion. The indicator
light. in the display comes on.
- The
approach warning is given when a de-
tected vehicle up ahead in your lane is mov-
ing much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. The indicator
light . and indicator in the display will
warn you about the danger ~
fig. 106. You
will also hear an acoustic signal.
ll This is not available in som e coun t ries.
If you do not react fast enough or do not react
at all to the situation, braking guard wi ll inter·
vene by braking and the message
braking
guard intervention
w ill appear.
- If a collision is imminent, the system wi ll
first provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake wit h increasing
force w ithin the limits of the system . This
reduces the vehicle speed in the event of a
collision.
- The system can initiate maximum braking
shortly before a collision
1
>. Full deceleration
at high speeds occurs only in vehicles with
adapt ive cruise control and side assist (pre
sense plus) .
- If the braking guard senses that you are not
braking hard enough when a collision is im·
minent, it can increase the brak ing force.
- The pre sense functions also engage when a
collision is imminent ~
page 194 .
Which functions can be controlled?
You can switch braking guard and the dis-
tance/approach warn ing on or off in the MMI
~ page 99, Settings in the MMI.
A WARNING
-
Lack of attention can cause collisions, oth-
er accidents and serious personal injuries .
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene . The dr iver is
always responsible for braking at the cor-
rect time.
- Always pay close attention to traffic,
even when the braking guard is switched
on. Be ready to intervene and be ready to
take comp lete control whenever necessa-
ry. Always keep the safe and legal dis-
tance between your vehicle and vehicles
up ahead.
- Braking guard works within limits and
will not respond outside the system
