Active Brake Assist (ABA) (system description)
Active Brake Assist (ABA) (system
description)
Active Brake Assist (ABA) is an assist-
ance system for critical driving situ-
ations. Active Brake Assist can help to
minimise the risk of colliding with the
vehicle in front or at least reduce the
severity of accident.
Active Brake Assist is merely an aid to
assist the driver.
Whenever Active Brake Assist detects a
hazardous situation, the driver is alerted
by an audible and a visual warning.
If there is a risk of a collision, the warn-
ing level is escalated and automatic par-
tial braking of the vehicle is initiated.
If the driver does not react to the warn-
ings, Active Brake Assist automatically
initiates emergency braking (full brake
application).
Note:
If distance cruise control is active, the
warnings of distance cruise control are
issued before those of Active Brake As-
sist. The warnings of Active Brake Assist
are still issued if distance cruise control is
not active.
Danger. Risk of accident.
Active Brake Assist does not relieve you
of the responsibility for adopting a driving
style which takes traffic and road condi-
tions into account. Deceleration by Active
Brake Assist may not be sufficient to pre-
vent a collision with the vehicle in front.
The driver is always responsible for the
speed driven, for initiating braking or
evasive manoeuvres in good time and
for maintaining a safe distance from the
vehicle in front. If Active Brake Assist
cannot interpret a traffic situation unequi-
vocally, it always transfers responsibility
for braking the vehicle to the driver. For
this reason, you should never rely on Act-
ive Brake Assist to brake the vehicle in
every situation. Do not wait until Active
Brake Assist initiates full braking. In the
following situations, you should brake the
bus manually using the service brake:
If the distance warning icon appears
on the display screen.
If a continuous and intermittent warn-
ing tone sounds.
If a continuous and intermittent warn-
ing tone sounds and automatic partial
braking has been initiated.
Danger. Risk of accident.
Active Brake Assist cannot always inter-
pret complex driving situations unequivoc-
ally. Active Brake Assist is able to issue
warnings and brake the vehicle only when
objects are identified unequivocally. Ob-
ject recognition may be particularly im-
paired if the distance sensor is dirty or
otherwise covered. This may also be the
case in snow or heavy rain. Active Brake
Assist does not react to persons, animals,
oncoming vehicles or cross traffic. Act-
ive Brake Assist may fail to detect narrow
vehicles, e.g. motorcycles.
If no visual and/or audible warning is giv-
en in a critical situation,
