Active Brake Assist (Aba) - Daimler Freightliner Cascadia 2021 Driver Manual

Detroit Assurance 4.0

Active Brake Assist (ABA)

Overview
Active Brake Assist is always on, automatically track-
ing the distance from the front of the tractor to other
vehicles in its path using bumper-mounted radar.
The radar tracks stationary objects in the vehicle's
path and has the capacity to engage full braking on
these objects, such as a parked vehicle or stopped
traffic.
The radar system can detect most pedestrians mov-
ing within the vehicle's path as long as they stay in
motion; the system can act to help mitigate a colli-
sion at vehicle speeds below 25mph (40 km/h). If the
system detects a pedestrian in motion within the
radar system's parameters for potential danger, the
vehicle will give a visual and auditory warning, and, if
the driver doesn't respond, engage in partial braking.
The radar may not detect pedestrians in every pos-
sible situation, nor is it a substitute for cautious driv-
ing.
Safety Information
WARNING
Active Brake Assist (ABA) is intended only as an
aid for a conscientious and alert driver. The
driver is responsible for keeping a safe distance
from the vehicle in front, for the vehicle speed,
braking in good time, and remaining in lane.
ABA does not take road and weather conditions
into account, nor the prevailing traffic situation.
The driver should always adapt driving style to
suit prevailing road and weather conditions.
ABA is not a substitute for safe driving proce-
dures.
Operate a vehicle equipped with Detroit Assur-
ance Collision Mitigation System as if the vehicle
were not equipped with a collision mitigation sys-
tem.
The Detroit Assurance Collision Mitigation Sys-
tem will not warn of hazards such as animals,
oncoming vehicles, or cross traffic.
Failure to drive safely and use the system prop-
erly could result in personal injury and/or death
and severe property damage.
If your vehicle is equipped with ABA, it can (within
system limitations):
5.5
•
react more quickly to an object in your path of
travel;
•
perform emergency braking; and
•
react to moving people with a warning and par-
tial braking.
Active brake assist can minimize the risk of a front-
end collision with a moving or stationary vehicle. If
ABA detects the risk of a front-end collision, it issues
an audible and visual warning. If the risk persists,
ABA automatically initiates partial braking of the ve-
hicle. If the driver does not react to the warnings and
partial brake application, ABA automatically initiates a
full brake application.
Active brake assist may detect moving people within
the vehicle's path and along the edge of the lane and
can act to help mitigate a collision at speeds below
25mph (40 km/h).
Active brake assist may not detect narrow vehicles,
like motorcycle, driving in front, or vehicles driving on
a different lane.
Active brake assist does not automatically adapt to
road and traffic conditions. Brake the vehicle using
the service brake if:
•
an event window with the warning symbol ap-
pears on the driver display screen;
•
an intermittent warning tone sounds; or
•
an intermittent warning tone sounds and auto-
matic partial braking was initiated.
If no visual and/or acoustic warning is issued in a
critical situation:
•
Active brake assist has not recognized the
danger of the situation; or
•
Active brake assist is suppressed; or
•
Active brake assist has failed.
Active brake assist-triggered emergency braking can
be deactivated if the driver presses the accelerator
pedal beyond the pressure point (kickdown).
IMPORTANT: If there is risk of a collision, adap-
tive cruise control (ACC) may warn the driver
before active brake assist (ABA).
