Intelligent Cruise Control
Maintains a preset distance from the vehicle ahead, reducing the driver's workload
Intelligent
Cruise
Control
(ICC)
measures
the
distance
from
the
vehicle
ahead
and
controls
acceleration
and
deceleration
to
automatically
maintain
a
suitable
following
distance.
This
distance
is
adjusted
according
to
the
speed
of
the
vehicle
ahead,
up
to
the
preset
speed,
and
the
ICC
speed
settings
set
by
the
driver.
ICC
reduces
the
driver's
workload
during
long
journeys
such
as
expressway
driving
or
in
traffic
congestion
situations.
The system controls vehicle speed in order to maintain a set distance from the vehicle ahead. Manual accelerator pedal operation is reduced in high speed driving or in traffic congestion, making the journey much easier for the driver.
System operation
When
the
ICC
system
detects
a
preceding
vehicle
driving
in
the
same
lane,
the
system
controls
acceleration
and
deceleration
in
order
to
maintain
the
preset
distance
between
vehicles
according
to
the
vehicle's
speed,
up
to
the
preset
speed,
and
ICC
speed
range
selected
by
the
driver.
If
the
preceding
vehicle
comes
to
a
stop,
the
driver's
vehicle
will
come
to
a
standstill
(within
the
limitations
of
the
system)
and
the
ICC
system
will
cancel.
In
situations
when
the
system
may
not
be
able
to
fully
decelerate
the
vehicle
due
to
the
preceding
vehicle
rapidly
decelerating,
or
a
vehicle
suddenly
merges
in
front
of
the
vehicle;
the
ICC
system
warns
the
driver
with
a
warning
chime
and
display
alert.
When
the
ICC
system
do
not
detect
a
vehicle
driving
ahead
in
the
same
lane,
the
system
maintains
the
vehicle
speed
that
was
set
by
the
driver.
On
some
models
such
as
the
Skyline,
the
ICC
system
also
modulates
vehicle
speed
according
to
the
size
of
a
curve
up
ahead,
utilizing
the
on-board
navigation
system
information.
After
clearing
the
curve,
the
vehicle
resumes
the
driver's
preset
speed.
System mechanism
The ICC system controls the acceleration and deceleration based on forward detection from a front-mounted radar sensor or front camera. Detection scope includes detecting a preceding vehicle in the same lane and the distance to it.
