emergency brake assis-
tance system (Front As-
sist)
Introduction
The objective of the system is to prevent head-
on collisions against objects that may be in the
vehicle’s path or minimise the consequences
of such impacts.
The function is designed to avoid collisions
against:
•
Parked vehicles.
•
Vehicles, pedestrians and cyclists that are
travelling in the same lane and direction.
•
Pedestrians and cyclists who transversely
cross the vehicle path.
The Front Assist records the mentioned ob-
jects by means of a camera on the top of the
windscreen and a radar sensor on the front of
the vehicle
.
Depending on several factors and how critical
the situation is, the system operates in a stag-
gered manner.
First informing the driver, and if there is no or
insufficient reaction, then activating an auton-
omous emergency braking or an evasive ma-
noeuvre as indicated by the conditions that will
be discussed in the following points.
The system can be cancelled if the accelerator
pedal is pressed or the steering wheel is turned
firmly.
Depending on the equipment and the coun-
try, the Front Assist also includes the following
functions:
•
Pedestrian protection
•
Cyclist protection
•
Dodge assist
•
WARNING
•
Front Assist is a driving assistance function
that can never replace the driver’s attention.
•
Front Assist cannot change the laws of
physics or replace the driver in terms of
keeping control of the vehicle and reacting
to a possible emergency situation.
•
Following a Front Assist emergency warn-
ing, pay immediate attention to the situation
and try to avoid the collision where appropri-
ate.
