Pilot Assist

Pilot Assist helps the driver to drive the car
between the lane's side markings using steering
assistance as well as to maintain an even speed,
combined with a preselected time interval to the
vehicle ahead.

How Pilot Assist works

The Pilot Assist function gives more comfortable
driving and a more relaxed driving experience
during, for example, long journeys on motorways
in even traffic flows.

The camera and radar unit measures the distance to the
vehicle ahead and detects side markings

Camera and radar unit

Distance readers

Readers, side markings

The driver selects the desired speed and a time
interval to the vehicle ahead. Pilot Assist scans
the distance to the vehicle ahead and the lane's
side markings on the road surface using the
camera and radar unit. The preset time interval is
maintained with automatic speed adjustment
whilst the steering assistance helps to position
the car in the lane.

Pilot Assist steering assistance takes into
account the speed of the preceding car and the
lane markings. The driver can at any time ignore
the Pilot Assist steering recommendation and
steer in another direction, e.g. to change lane or
avoid an obstruction on the road.

If Pilot Assist cannot interpret the lane unambig-
uously, e.g. if the camera and radar unit does not
see the lane's side markings, Pilot Assist tempo-
rarily deactivates steering assistance, but
resumes it if the lane can be interpreted again -
although the speed and distance control func-
tions remain active.

WARNING

Pilot Assist steering assistance is automati-

cally deactivated and is resumed without prior

warning.

The current status of steering
assistance is indicated by the
colour of the steering wheel's
symbol:

• GREEN steering wheel indi-
cates active steering assis-

tance

• GREY steering wheel (as in illustration) indi-
cates deactivated steering assistance.

NOTE: The illustration is schematic - details may vary depending on car model.

DRIVER SUPPORT

318

WARNING

•

The Pilot Assist function is supplementary
driver support intended to facilitate driv-
ing and make it safer – it cannot handle
all situations in all traffic, weather and
road conditions.

•

The driver is advised to read all sections
in the Owner's Manual that relate to this
function to learn about factors such as its
limitations and what the driver should be
aware of before using the system (see
the list of links at the end of this article).

•

Pilot Assist must only be used if there are
clear lane lines painted on each side of
the lane. All other use involves increased
risk of contact with surrounding obstacles
that cannot be detected by the function.

•

Pilot Assist is not a substitute for the driv-
er's attention and judgement. The driver
is always responsible for ensuring the car
is driven in a safe manner, positioned cor-
rectly in the lane, at the appropriate
speed, with an appropriate distance to
other vehicles, and in accordance with
current traffic rules and regulations.

Pilot Assist regulates the speed with acceleration
and braking. It is normal for the brakes to emit a
low sound when they are being used to adjust
the speed.

Pilot Assist attempts to regulate the speed
smoothly. In situations that demand sudden brak-
ing the driver must brake himself/herself. This
applies in case of large speed differences or if
the vehicle in front brakes suddenly. Due to the
limitations of the camera and radar unit, braking
may come unexpectedly or not at all.

Pilot Assist aims to follow the vehicle ahead in
the same lane at a time interval set by the driver.
If the radar unit cannot see any vehicle in front
then the car will instead maintain the speed set
and stored by the driver. This also takes place if
the speed of the vehicle ahead increases and
exceeds the stored speed.

The following applies for cars with automatic
gearbox:

•

Pilot Assist can follow another vehicle at
speeds from 0 km/h up to 200 km/h
(125 mph).

•

Pilot Assist can give steering assistance from
almost stationary up to 140 km/h (87 mph).

The following applies for cars with manual gear-
box:

•

Pilot Assist can follow another vehicle at
speeds from 30 km/h (20 mph) up to
200 km/h (125 mph).

•

Pilot Assist can give steering assistance from
30 km/h (20 mph) up to 140 km/h
(87 mph).

WARNING

•

Pilot Assist is not a collision avoidance
system. The driver must intervene if the
system does not detect a vehicle in front.

•

Pilot Assist does not brake for people,
animals, objects, small vehicles (e.g.
cycles and motorcycles), low trailers as
well as oncoming, slow or stationary vehi-
cles.

•

Do not use Pilot Assist in demanding sit-
uations, such as in city traffic, at junctions,
on slippery surfaces, with a lot of water or
slush on the road, in heavy rain/snow, in
poor visibility, on winding roads, on slip
roads, or with a trailer connected to the
car.

IMPORTANT

Maintenance of Pilot Assist internal compo-
nents must only be performed at a workshop
- an authorised Volvo workshop is recom-
mended.

Round bends and when the road splits

Pilot Assist interacts with the driver, who should
therefore not await the steering assistance from
Pilot Assist but should always be prepared to
increase his/her own steering input, especially on
bends.

DRIVER SUPPORT

}}

319

When the car approaches an exit or if the lane
splits, the driver should steer towards the desired
lane so that Pilot Assist can specify the desired
direction.

Pilot Assist strives to keep the car in
the middle of the lane

When Pilot Assist helps to steer, it strives to posi-
tion the car in between the lane markings and
therefore it is recommended to let the car find
the optimal placement to achieve as smooth a
driving experience as possible. The driver checks
that the car is positioned safely in the lane, and
always has the ability to adjust the position by
making his/her own steering corrections.

If Pilot Assist does not position the car in an
appropriate way in the lane, it is recommended to
turn Pilot Assist off or switch to Adaptive cruise
control.

Collision risk warning

Warning light for collision warning on the windscreen

Pilot Assist uses approx. 40% of the foot brake's
capacity. If the car needs to be braked more
heavily than Pilot Assist is capable of and the
driver does not brake, the warning lamp and
acoustic warning are activated to alert the driver
that immediate intervention is required.

NOTE

Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the vis-
ual warning signal in the windscreen difficult
to recognise.

WARNING

Pilot Assist only gives warning about vehicles

detected by its camera and radar unit – there-

fore a warning may not occur or be delayed.

•

Never wait for a warning. Apply the
brakes when the situation requires!

NOTE: The illustration is schematic - details may vary depending on car model.

Pilot Assist must first be activated and then
started to be able to control speed and distance
and to give steering assistance.

NOTE: The illustration is schematic - details may vary

depending on car model.

In order to start the Pilot Assist it is required that:

•

The driver's seatbelt must be buckled and
the driver's door must be closed.

•

There must be a vehicle (the "target vehicle")
within reasonable distance in front of the car,
or the current speed must be at least
15 km/h (9 mph).

•

For cars with manual gearbox. Speed must
be at the lowest 30 km/h (20 mph).

NOTE: The illustration is schematic - details may vary depending on car model.

With the Adaptive cruise control in standby
mode:

1. Press the steering wheel button ▶ (6).

> The

symbol changes to Pilot Assist

in standby mode (8).

2. Press the steering wheel button

(2).

> Pilot Assist is started and current speed is

stored, which is shown with figures in the
centre of the speedometer.

...or...

With the Adaptive cruise control started:

–

Press the steering wheel button

▶ (6).

> Pilot Assist is started.

Pilot Assist steering assistance
is only active when the steering
wheel symbol (2) has changed
from GREY to GREEN.

Pilot Assist only regulates the
time interval to the vehicle

ahead when the distance symbol shows a vehicle
(1) above the steering wheel symbol.

At the same time a speed
range is marked.

The higher speed is the
stored/selected speed and the
lower speed is that of the vehi-
cle ahead (target vehicle).

Hands on the steering wheel

In order for Pilot Assist to function, the driver’s
hands must be on the steering wheel. If Pilot
Assist detects that the driver is not holding the
steering wheel, the driver is prompted to actively
steer the car via a text message and an acoustic
signal.

If Pilot Assist still cannot detect that the driver is
holding the steering wheel, the function shifts to
standby mode. Pilot Assist must then be restar-
ted with the steering wheel button

NOTE

Note that Pilot Assist only works when the
driver has hands on the steering wheel.

Managing the speed for

Pilot Assist

Pilot Assist can be set to different speeds.

Setting/changing the stored speed

NOTE: The illustration is schematic - details may vary

depending on car model.

–

Change the set speed with short or long
presses on steering wheel button

(1) or

(3):

•

Short press: Each press changes the
speed in increments of +/- 5 km/h
(+/- 5 mph).

•

Press and hold: Release the button when
the set speed indicator (4) has moved to
the desired speed.

•

The speed set after the last button press is
stored in the memory.

If the driver increases the car’s speed using the
accelerator pedal before pressing the steering
wheel button

, the speed stored will be the

car’s speed when the button is depressed, provi-
ded the driver’s foot is on the accelerator pedal at
the moment when the button is depressed.

A temporary increase in speed with the accelera-
tor pedal, e.g. during overtaking, does not affect
the setting - the car returns to the last stored
speed when the accelerator pedal is released.

Automatic gearbox

Pilot Assist can follow another vehicle at speeds
from 0 km/h up to 200 km/h (125 mph).

Note that the lowest programmable speed for
Pilot Assist is 30 km/h (20 mph) - even though it
is capable of following another vehicle down to 0
km/h, a speed lower than 30 km/h (20 mph)
cannot be selected/stored.

The maximum speed selectable is 200 km/h
(125 mph).

Manual gearbox

Pilot Assist can follow another vehicle at speeds
from 30 km/h (20 mph) up to 200 km/h
(125 mph).

The lowest programmable speed for Pilot Assist
is 30 km/h (20 mph) - the maximum speed is
200 km/h (125 mph).

Setting the time interval for

Pilot Assist

Pilot Assist can be set with different time inter-
vals.

Different time intervals to the
vehicle in front can be selected
and shown in the driver display
as 1-5 horizontal lines - the
more lines the longer the time
interval. One line represents
about 1 second to the vehicle

in front, 5 lines represents about 3 seconds.

NOTE

When the symbol in the driver display shows
a car and a steering wheel, Pilot Assist fol-
lows a vehicle in front at a preset time gap.

When only one steering wheel is shown, there
is no vehicle within a reasonable distance
ahead.

Control for time interval.

Decrease time interval

Increase time interval

Distance indicator

–

Press the steering wheel button (1) or (2) to
increase or decrease the time interval.
> The distance indicator (3) shows the cur-

rent time interval.

In order to follow the vehicle ahead in a smooth
and comfortable way, Pilot Assist allows the time
interval to vary noticeably in certain conditions.
For example, at low speed, when the distances
become short, Pilot Assist increases the time
interval slightly.

NOTE

•

The higher the speed the longer the cal-
culated distance in metres for a given
time interval.

•

Only use the time intervals permitted by
local traffic regulations.

•

If Pilot Assist does not seem to respond
with a speed increase when activated, it
may be because the time window to the
vehicle ahead is shorter than the set time
window.

WARNING

•

Only use a time window that suits the
current traffic conditions.

•

The driver should be aware that short
time windows limit the amount of time
available to react and take action if an
unexpected traffic situation arises.

Select how Pilot Assist shall maintain
the distance

* to the vehicle ahead

The driver can select different driving styles for
how Pilot Assist should maintain the preset time
interval to the vehicle ahead. Selection is made
via the drive mode control DRIVE MODE.

DRIVER SUPPORT

}}

* Option/accessory.

325

Select one of the following alternatives:

•

Eco

- ACC focuses on optimal fuel economy,

which means longer time interval to the vehi-
cle ahead.

•

Comfort

- Pilot Assist focuses on following

the set time interval to the vehicle ahead as
smoothly as possible.

•

Dynamic

- Pilot Assist focuses on following

the set time interval to the vehicle ahead
more closely, which in certain cases may
mean heavier acceleration and braking.

...or...

DRIVER SUPPORT

326

–

Press the steering wheel button

◀ (3).

> Pilot Assist is switched off and changes

to the Adaptive cruise control in active
mode.

WARNING

•

With Pilot Assist in standby mode, the
driver must intervene and steer, regulat-
ing both speed and distance to the vehi-
cle ahead.

•

When Pilot Assist is in standby mode and
the car comes too close to a vehicle
ahead, the driver is warned of the short
distance by the Distance Warning func-
tion instead.

Standby mode on driver intervention

Pilot Assist is temporarily deactivated and set in
standby mode if:

•

the foot brake is used

•

the gear selector is moved to N position

•

the direction indicators are used for longer
than 1 minute.

•

the driver maintains a speed higher than the
stored speed for longer than 1 minute.

•

the clutch pedal is depressed for
approx. 1 minute - applies to cars with man-
ual gearbox.

A temporary increase in speed with the accelera-
tor pedal, e.g. during overtaking, does not affect
the setting - the car returns to the last stored
speed when the accelerator pedal is released.

When the direction indicators are used, Pilot
Assist steering assistance is temporarily disen-
gaged. When this is no longer the case, steering
assistance is automatically reactivated if the
lane's side markings can still be detected.

Automatic standby mode

Pilot Assist is dependent on other systems, e.g.
stability control/anti-skid ESC

. If any of these

other systems stops working, Pilot Assist is
switched off automatically.

WARNING

With automatic standby mode, the driver is

warned via an acoustic signal and a message

on the driver display.

•

The driver must then regulate the car's
speed, apply the brakes as needed and
maintain a safe distance to other vehicles.

Automatic standby mode may occur if, for exam-
ple:

•

the driver opens the door

•

brake temperature is high

•

the driver's hands are not on the steering
wheel

•

the parking brake is applied

•

engine speed is too low/high

•

the driver takes off the seatbelt

•

one or more wheels lose traction

•

the camera and radar unit is covered by e.g.
snow or heavy rainfall (camera lens/radio
waves are blocked)

•

the speed is below 5 km/h (3 mph) and Pilot
Assist is uncertain whether the vehicle ahead
is a stationary vehicle or an object, such as a
speed bump.

•

the speed is below 5 km/h (3 mph) and the
vehicle ahead turns off so that Pilot Assist no
longer has a vehicle to follow.

•

speed is reduced to below 30 km/h
(20 mph) - only applies to cars with manual
gearbox.

Change of target and automatic

braking with Pilot Assist

In combination with automatic gearbox, Pilot
Assist has functionality for change of target and
braking at certain speeds.

Change of target

If the target vehicle in front suddenly turns then there

may be stationary traffic in front.

When Pilot Assist is following another vehicle at
speeds below 30 km/h (20 mph) and changes
target from a moving to a stationary vehicle, Pilot
Assist will slow down for the stationary vehicle.

DRIVER SUPPORT

* Option/accessory.

328

WARNING

When Pilot Assist is following another vehicle

at speeds in excess of approx. 30 km/h

(20 mph) and the target is changed from a

moving vehicle to a stationary vehicle, Pilot

Assist will ignore the stationary vehicle and

instead accelerate to the stored speed.

•

The driver must then intervene him/
herself and brake.

Automatic standby mode with change of
target

Pilot Assist is disengaged and set in standby
mode:

•

when the speed is below 5 km/h (3 mph)
and Pilot Assist is uncertain whether the tar-
get object is a stationary vehicle or some
other object, e.g. a speed bump.

•

when the speed is below 5 km/h (3 mph)
and the vehicle in front turns off so the Pilot
Assist no longer has a vehicle to follow.

Automatic braking

For shorter stops in connection with inching in
slow traffic or at traffic lights, driving is automati-
cally resumed if the stops do not exceed
approx. 3 seconds - if it takes longer before the
vehicle in front starts moving again then Pilot
Assist is set in standby mode with automatic
braking.

–

Pilot Assist is reactivated in the following
way:

•

Press the steering wheel button

•

Depress the accelerator pedal.

> Pilot Assist resumes following the vehicle

ahead if it starts moving forward within
6 seconds.

NOTE

Pilot Assist can hold the car stationary for a
maximum of 5 minutes - then the parking
brake is applied and the function is disen-
gaged.

Before Pilot Assist can be reactivated, the
parking brake must be released.

Cessation of automatic braking

In some situations, automatic braking ceases on
coming to a standstill and Pilot Assist is set in
standby mode. This means that the brakes are
released and the car may start to roll - the driver
must therefore intervene and brake the car him-
self/herself to keep it stationary.

This may take place in the following situations:

•

the driver puts his/her foot on the brake
pedal

•

the parking brake is applied

•

the gear selector is moved to P, N, or R posi-
tion

•

the driver sets Pilot Assist in the standby
mode.

Automatic activation of parking brake

In certain situations, the parking brake is applied
in order to keep the car stationary.

This takes place if Pilot Assist is holding the car
stationary with the foot brake and:

•

the driver opens the door or takes off his/her
seatbelt

•

Pilot Assist has kept the car stationary for
more than approx. 5 minutes

•

the brakes have overheated

•

the engine is switched off.

Limitations of Pilot Assist

The Pilot Assist function may have limitations in
certain situations.

The Pilot Assist function is an aid which can help
the driver in many situations. But the driver is at
all times responsible for maintaining a safe dis-
tance to surrounding objects and a correct posi-
tion in the lane.

WARNING

In certain situations, Pilot Assist steering

assistance may have difficulty helping the

driver in the right way or it may be automati-

cally deactivated - in which case, the use of

Pilot Assist is not recommended. Examples of

such situations may be that:

•

the lane markings are worn, missing or
cross each other.

•

lane division is unclear, for example, when
the lanes divide or merge or at exits or in
the event of multiple sets of markings.

•

edges or other lines than lane markings
are present on or near the road, e.g.
kerbs, joints or repairs to the road sur-
face, edges of barriers, roadside edges or
strong shadows.

•

the lane is narrow or winding.

•

the lane contains ridges or holes.

•

weather conditions are poor, e.g. rain,
snow or fog or slush or impaired view with
poor light conditions, back-lighting, wet
road surface etc.

The driver should also note that Pilot Assist

has the following limitations:

•

High kerbs, roadside barriers, temporary
obstacles (traffic cones, safety barriers,
etc.) are not detected. Alternatively, they
may be detected incorrectly as lane mark-
ings, with a subsequent risk of contact

between the car and such obstacles. The
driver must ensure him/herself that the
car is at a suitable distance from such
obstacles.

•

The camera and radar sensor does not
have the capacity to detect all oncoming
objects and obstacles in traffic environ-
ments, e.g. potholes, stationary obstacles
or objects which completely or partially
block the route.

•

Pilot Assist does not "see" pedestrians,
animals, etc.

•

The recommended steering input is force
limited, which means that it cannot always
help the driver to steer and keep the car
within the lane.

The driver always has the possibility of correcting
or adjusting a steering intervention imposed by
Pilot Assist and can turn the steering wheel to
the desired position.

Steep roads and/or heavy load

Bear in mind that Pilot Assist is primarily
intended for use when driving on level road surfa-
ces. The function may have difficulty in keeping
the correct distance from the vehicle ahead when
driving on steep downhill slopes - in which case,
be extra attentive and ready to brake.

•

Do not use Pilot Assist if the car has a heavy
load or a trailer is connected to the car.

DRIVER SUPPORT

* Option/accessory.

330

NOTE

Pilot Assist cannot be activated if a trailer,
bicycle rack or similar is connected to the
car's electrical system.

Miscellaneous

•

Off Road

drive mode cannot be selected

when Pilot Assist is activated.

NOTE

The function uses the car's camera unit,
which has some general limitations, see the
"Limitations for camera unit" section.

NOTE

The function uses the car's radar unit, which
has some general limitations, see the section
"Limitations for radar unit".
