4-5. Using the driving support systems
LS500h_OM_OM50F42U_(U)
■ Parking Support Brake function (rear
pedestrians) will operate when
The function will operate when the PKSB
OFF indicator is not illuminated or flashing
(→P.73, 74) and all of the following condi-
tions are met:
● Hybrid system output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is 10 mph (15 km/h) or
less.
• The shift position is in R.
• The rear camera sensor detects a pedes-
trian behind the vehicle while backing up
and the system determines that the possi-
bility of colliding with the detected
pedestrian is high.
● Brake control
• Hybrid system output restriction control
is operating.
• The Parking Support Brake determines
that an emergency brake operation is
necessary to avoid a collision with a
pedestrians.
■ The Parking Support Brake function
(rear pedestrians) will stop operating
when
The function will stop operating if any of the
following conditions are met:
● Hybrid system output restriction control
• The Parking Support Brake is disabled.
• The collision becomes avoidable with
normal brake operation.
• The pedestrian is no longer detected
behind your vehicle.
● Brake control
• The Parking Support Brake is disabled.
• Approximately 2 seconds have elapsed
since the vehicle was stopped by brake
control.
• The brake pedal is depressed after the
vehicle is stopped by brake control.
• The pedestrian is no longer detected
behind your vehicle.
■ Detection area of the Parking Support
Brake function (rear pedestrians)
The detection area of the Parking Support
Brake function (rear pedestrians) differs
from the detection area of the RCD func-
tion (→P.278). Therefore, even if the RCD
function detects a vehicle and provides an
alert, the Parking Support Brake function
(rear-crossing vehicles) may not start oper-
ating.
■ Situations in which the system may not
operate properly
● Some pedestrians, such as the following,
may not be detected by the Parking Sup-
port Brake function (rear pedestrians),
preventing the function from operating
properly:
• Pedestrians who are bending forward or
squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the
detection area
• Pedestrians riding a bicycle, skateboard,
or other light vehicle
• Pedestrians wearing oversized clothing
such as a rain coat, long skirt, etc., making
their silhouette obscure
• Pedestrians whose body is partially hid-
den by an object, such as a cart or
umbrella
• Pedestrians which are obscured by dark-
ness, such as at night
● In some situations, such as the following,
pedestrians may not be detected by the
Parking Support Brake function (rear
pedestrians), preventing the function
from operating properly:
• When backing up in inclement weather
(rain, snow, fog, etc.)
• When the rear camera is obscured (dirt,
snow, ice, etc. are attached) or scratched
• When a very bright light, such as the sun,
or the headlights of another vehicle,
shines directly into the rear camera
• When backing up in a place where the
surrounding brightness changes sud-
■ If the Parking Support Brake function
(rear pedestrians) operates unneces-
sarily
Depress the brake pedal immediately
after the Parking Support Brake function
(rear pedestrians) operates. (Operation
of the function is canceled by depressing
the brake pedal.)
