Active City Brake
Active City B rake i s a d riving a ssistance s ystem t
hat aims to avoid a frontal collision or reduce
t
he speed of an impact if the driver does not
r
eact or reacts too late (brake application too
l
ate). This
system is designed to improve
d
riving safety.
It
remains the driver's responsibility to
c
ontinuously monitor the state of the
t
raffic and to assess the distances and
r
elative speeds of other vehicles.
Active
City Brake can in no
c
ircumstances replace the need for
v
igilance on the part of the driver.
Never
look at the laser sensor through
a
n optical instrument (magnifying glass,
m
icroscope...) at a distance of less than
1
0 centimetres: risk of eye injury.Automatic
braking occurs later than if
d
one by the driver, so as to intervene
o
nly when there is a high risk of
c
ollision.Principle
Using a laser sensor and a camera located at the top of the windscreen, this system detects
a
vehicle running in the same direction or
s
tationary ahead of your vehicle.
When
necessary, the vehicle's braking system
i
s operated automatically to reduce the speed
o
f impact or to help avoid a collision with the
v
ehicle
a
head.
Conditions for activation
Active City Brake only operates if the following
c onditions are met:
●
t
he engine is running,
●
t
he vehicle is in a for ward gear,
●
t
o trigger the pre-collision alert :
-
t
he speed is between 9 and 87 mph
(
15 and 140 km/h),
-
t
he difference in speed between your
v
ehicle and the one ahead is more than
a
bout 9 mph (15 km/h),
●
f
or braking assistance :
-
t
he speed is between about 18 and
5
0 mph (30 and 80 km/h),
-
t
he difference in speed between your
v
ehicle and the one ahead is more than
a
bout 18 mph (30 km/h),
●
f
or automatic pre-collision braking:
-
t
he speed is between about 6 and
5
0 mph (10 and 80 km/h),
-
t
he difference in speed between your
v
ehicle and the one ahead is more than
a
bout 6 mph (10 km/h),
●
t
he braking assistance systems (ABS,
E
BFD, EBA) are not faulty,
●
t
he trajectory control systems (TRC, DSC)
a
re not deactivated or faulty,
●
t
he vehicle is not in a tight corner,
●
t
he system has not been triggered during
t
he previous 10 seconds.
