Detecting obstacles with City Safety

City Safety can help detect vehicles, cyclists,
large animals and pedestrians.

Vehicles

City Safety detects most types of vehicles that
are either stationary, moving in the same direc-
tion as your vehicle or those described in “City
Safety in crossing traffic” and City Safety braking
for oncoming vehicles”.

For City Safety to be able to detect a vehicle in
the dark, its headlights and taillights must be on
and clearly visible.

Cyclists

Optimal examples of what City Safety would interpret to
be a cyclist: clear body and bicycle shapes.

For optimal performance, the system's function
for cyclist detection needs the clearest possible
information about the contours of the bicycle and

of the cyclist's head, arm, shoulders, legs, torso
and lower body in combination with normal
human movements.

If large portions of the cyclist's body or the bicy-
cle itself are not visible to the function's camera,
it will not be able to detect a cyclist.

The system can only detect adult cyclists riding
on bicycles intended for adults.

WARNING

City Safety is supplementary driver support,

but it cannot detect all cyclists in all situations

and, for example, cannot see:

•

partially obscured cyclists.

•

cyclists if the background contrast of the
cyclist is poor - warning and brake inter-
ventions may then be late or not occur at
all.

•

cyclists in clothing that hides their body
contour.

•

bikes loaded with large objects.

The driver is always responsible for ensuring

that the vehicle is driven correctly and with a

safety distance suitable for the speed.

Pedestrians

Optimal examples of what the system considers to be a
pedestrian: clear body contours.

For optimal performance, the system's function
for pedestrian detection needs the clearest pos-
sible information about body and bicycle con-
tours. This entails being able to detect the con-
tours of the pedestrian's head, arm, shoulders,
legs, torso and lower body in combination with
normal human movements.

In order to detect a pedestrian, there must be a
contrast to the background, which could depend
on clothing, weather conditions, etc. If there is lit-
tle contrast, the person may be detected late or
not at all, which may result in a delayed reaction
from the system or no reaction at all.

City Safety can detect pedestrians even in dark
conditions if they are illuminated by the vehicle's
headlights.

WARNING

City Safety is supplementary driver support,

but it cannot detect all pedestrians in all sit-

uations and, for example, cannot see:

•

partially obscured pedestrians, people in
clothing that hides their body contour or
pedestrians shorter than 80 cm (32 in.).

•

pedestrians if the background contrast of
the pedestrians is poor - warning and
brake interventions may then be late or
not occur at all.

•

pedestrians who are carrying large
objects.

The driver is always responsible for ensuring

that the vehicle is driven correctly and with a

safety distance suitable for the speed.

Large animals

Optimal examples of what City Safety would interpret as
a large animal: stationary or moving slowly and with clear
body contours.

For optimal performance, the system's function
for detecting large animals (e.g. moose, horses,
etc.) needs the clearest possible information
about body contours. This entails being able to
detect the animal straight from the side in combi-
nation with normal movements for that animal.

If parts of the animal's body are not visible to the
function's camera, the system will not be able to
detect the animal.

City Safety can detect large animals even in dark
conditions if they are illuminated by the vehicle's
headlights.

WARNING

City Safety is supplementary driver support,

but it cannot detect all large animals in all sit-

uations and, for example, cannot see:

•

partially obscured larger animals.

•

larger animals seen from the front or from
behind.

•

running or fast moving larger animals.

•

larger animals if the contrast of the ani-
mal's background is poor - warning and
brake interventions may then occur late
or not at all.

•

smaller animals such as cats and dogs.

The driver is always responsible for ensuring

that the vehicle is driven correctly and with a

safety distance suitable for the speed.

City Safety in crossing traffic

City Safety can assist the driver when turning in
the path of an oncoming vehicle in an intersec-
tion.

: Sector in which City Safety can detect an oncoming

vehicle in crossing traffic.

In order for City Safety to detect an oncoming
vehicle in situations where there is a risk of a col-
lision, that vehicle must be within the sector in
which City Safety can analyze the situation.

The following criteria must also be met:

•

your vehicle's speed must be at least 4 km/h
(3 mph)

•

your vehicle must be making a left turn

•

the oncoming vehicle's headlights must be
on

WARNING

•

The "City Safety in crossing traffic" func-
tion is supplementary driver support
intended to improve driving safety – it
cannot handle all situations in all traffic,
weather and road conditions.

•

Warnings and brake interventions due to
a collision risk with an oncoming vehicle
often come very late.

•

Never wait for a collision warning or for
City Safety to intervene.

•

City Safety is not a substitute for the driv-
er's attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

Limitations of City Safety in

crossing traffic

In certain situations, it may be difficult for City
Safety to help the driver avoid a collision with
crossing traffic.

For example:

•

on slippery roads when Electronic Stability
Control (ESC) is actively operating

•

if an approaching vehicle is detected at a late
stage

•

if the oncoming vehicle is partially obstructed
by another vehicle or object

•

if the oncoming vehicle's headlights are off

•

if the oncoming vehicle is moving erratically
and e.g. suddenly changes lanes at a late
stage.

The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".

City Safety and delayed evasive

maneuvers

City Safety can assist the driver by automatically
braking the vehicle when it is not possible to
avoid a collision by steering alone.

City Safety assists the driver by periodically
attempting to predict possible "escape routes" to
the sides of the vehicle in the event a slow-mov-
ing or stationary vehicle were to be detected at a
late stage.

Your vehicle (1) cannot detect any potential escape
routes for veering away from the vehicle ahead (2) and
may therefore apply the brakes at an earlier stage.

Own vehicle

Slow-moving/stationary vehicles

City Safety will not intervene to automatically
apply the brakes if it is possible for the driver to
avoid a collision by steering the vehicle.

However, if City Safety determines that an eva-
sive maneuver would not be possible due to traf-
fic in the adjacent lane(s), the function can assist
the driver by automatically starting to apply the
brakes at an earlier stage.

WARNING

•

The possibility of City Safety predicting a
certain situation is supplementary driver
support intended to improve driving safety
– it cannot handle all situations in all traf-
fic, weather and road conditions.

City Safety braking for oncoming

vehicles

City Safety can help you apply the brakes for an
oncoming vehicle in your lane.

If an oncoming vehicle veers into your lane and a
collision is unavoidable, City Safety can help
reduce your vehicle's speed to attempt to miti-
gate the force of the collision.

Own vehicle

Oncoming vehicles

The following criteria must be met for the func-
tion to work:

•

your vehicle's speed must be above 4 km/h
(3 mph)

•

the road must be straight

•

your lane must have clear side lane markings

•

your vehicle must be positioned straight in
your lane

•

the oncoming vehicle must be positioned
within your vehicle's lane markings

•

the oncoming vehicle's headlights must be
on

•

the function can only handle “front-to-front”
collisions

•

the function can only detect vehicles with
four wheels

•

the function requires functioning Electric
Seat Belt Tensioners (see section “Seat
belt tensioners”).

The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".

WARNING

•

The "City Safety braking for oncoming
vehicles" function is supplementary driver
support intended to help improve driving
safety – it cannot handle all situations in
all traffic, weather and road conditions.

•

Warnings and brake interventions due to
an imminent collision with an oncoming
vehicle always come very late.

•

Never wait for a collision warning or for
City Safety to intervene. If you notice any
hazard or other potentially dangerous sit-
uation, always fully apply the brakes.

City Safety limitations

City Safety functionality may be reduced in cer-
tain situations.

Surroundings

Low objects

Hanging objects, such as flags for overhanging
loads or accessories such as auxiliary lights or
front protective grids that extend beyond the
height of the hood, may limit City Safety function-
ality.

Slippery road conditions

The extended braking distance on slippery roads
may reduce City Safety's capacity to help avoid a
collision. In these types of situations, the Anti-
lock Braking System and Electronic Stability Con-
trol (ESC

) will help provide optimal braking

power with maintained stability.

Backlighting

The visual warning signal in the windshield may
be difficult to detect in bright sunlight, if there are
reflections, or if the driver is wearing sunglasses
or not looking straight ahead.

Heat

If the temperature in the passenger compartment
is high due to e.g. bright sunlight, the visual warn-
ing signal in the windshield may be temporarily
disabled.

Camera and radar sensor's field of vision

The camera's field of vision is limited and in cer-
tain situations, it may be unable to detect pedes-
trians, large animals, cyclists or vehicles, or it may
detect them later than expected.

Vehicles that are dirty may be detected later than
clean vehicles, and in dark conditions, motorcy-
cles may be detected late or not at all.

If a text message displayed in the instrument
panel indicates that the camera/radar sensor is
obstructed, it may be difficult for City Safety to
detect pedestrians, large animals, cyclists, vehi-
cles or lane markings in front of the vehicle. City
Safety functionality may therefore be reduced.

Text messages may not be displayed for all situa-
tions in which the windshield sensors are
blocked. The driver must therefore always keep
the windshield in front of the camera/radar sen-
sor clean.

CAUTION

Maintenance and replacement of City Safety
components may only be performed by a
workshop – an authorized Volvo workshop is
recommended.

Driver intervention

Backing up

City Safety is temporarily deactivated when the
vehicle is backing up.

Low speed

City Safety is not activated at very low speeds
under 4 km/h (3 mph). The system will therefore
not intervene in situations in which your vehicle is
approaching another vehicle very slowly, such as
when parking.

Active driver

Action by the driver always has priority. City
Safety will therefore not react or will react at a
later stage with a warning or intervention in situa-
tions in which the driver is clearly steering and
operating the accelerator pedal, even if a collision
is unavoidable.

An active and aware driving style may therefore
delay collision warnings and intervention in order
to minimize unnecessary warnings.

Other limitations

WARNING

•

Warnings and brake interventions can be
triggered late or not at all if the traffic sit-
uation or external influences prevent the
camera and radar unit from properly
detecting pedestrians, cyclists, large ani-
mals or vehicles ahead of the vehicle.

•

To be able to detect vehicles at night, its
front and rear lights must work and illumi-
nate clearly.

•

The camera and radar unit have a limited
range for pedestrians and cyclists – the
system can provide effective warnings
and brake interventions if the relative
speed is lower than 50 km/h (30 mph).
For stationary or slow-moving vehicles,
warnings and brake interventions are
effective at vehicle speeds of up to
70 km/h (43 mph). Speed reduction for
large animals is less than 15 km/h
(9 mph) and can be achieved at vehicle
speeds over 70 km/h (43 mph). At lower
speeds, the warning and brake interven-
tion for large animals is less effective.

•

Warnings for stationary or slow-moving
vehicles and large animals can be disen-
gaged due to darkness or poor visibility.

•

Warnings and brake interventions for
pedestrians and cyclists are disengaged
at vehicle speeds over 80 km/h
(50 mph).

•

Do not place, affix or mount anything on
the inside or outside of the windshield, or
in front of or around the camera and
radar unit – this could disrupt camera-
based functions.

•

Objects, snow, ice or dirt in the area of
the camera sensor can reduce the func-
tion, disengage it completely or give an
improper function response.

The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".

Rear Collision Warning limitations (p. 346)

DRIVER SUPPORT

346

Rear Collision Warning

The Rear Collision Warning (RCW) function can
help the driver avoid rear-end collisions from
vehicles approaching from behind.

RCW is automatically activated each time the
engine is started.

RCW can warn the driver of a potential collision
with vehicles approaching from behind by rapidly
flashing the turn signals.

If, at a speed below 30 km/h (20 mph), the RCW
function detects that the car is in danger of being
hit from behind, the seatbelt tensioners may ten-
sion the front seatbelts and activate the Whiplash
Protection System safety system.

Immediately before a collision from behind, RCW
may also activate the foot brake in order to
reduce the forward acceleration of the car during
the collision. However, the brakes will only be
applied if your vehicle is stationary. The brakes
will be immediately released if the accelerator
pedal is depressed.

Whiplash Protection System (p. 46)

Rear Collision Warning limitations

In some situations, it may be difficult for RCW to
warn the driver of a collision risk.

This may be the case if:

•

the vehicle approaching from the rear is
detected at a late stage

•

the vehicle approaching from the rear
changes lanes at a late stage

•

the vehicle approaching from the rear is mov-
ing at a speed above 80 km/h (50 mph)

•

a trailer, bicycle holder or similar is con-
nected to the vehicle's electrical system - the
RCW function will then be automatically
deactivated.

In certain markets RCW does not warn with
the direction indicators due to local traffic
regulations – in such cases, that part of the
function is deactivated.

Rear Collision Warning (p. 346)
