Operation starting conditions
■
When the PKSB OFF indicator is not illumi-
nated or flashing (P.253, 390) and all of
the following conditions are met, the system
operates.
● Hybrid system output restriction control
• The Parking Support Brake function (for
static objects) is on.
• The vehicle speed is 10 mph (15 km/h) or
less.
• There is a static object in the traveling
direction of the vehicle (6 to 13 ft. [2 to 4
m] ahead).
• The system determined that a stronger-
than-normal brake operation was neces-
sary to avoid a collision.
Brake control
●
• Hybrid system output restriction control
is being performed.
• The system determined that an emer-
gency brake operation was necessary to
avoid a collision.
Operation ending conditions
■
In any of the following situations, the system
stops operating.
Hybrid system output restriction control
●
• The Parking Support Brake function (for
static objects) has been turned off
(stopped).
• The collision became avoidable with nor-
mal brake operation.
• The static object is no longer in the travel-
ing direction of the vehicle (6 to 13 ft. [2
to 4 m] ahead).
Brake control
●
• The Parking Support Brake function (for
static objects) has been turned off
(stopped).
• Approximately 2 seconds elapsed after
the vehicle was stopped by brake control.
• The brake pedal was depressed after the
vehicle was stopped by brake control.
• The static object is no longer in the travel-
ing direction of the vehicle (6 to 13 ft. [2
to 4 m] ahead).
Sensor detection range
■
The detection range of the Parking Support
Brake function (for static objects) differs
from the detection range of the clearance
sonar (P.250).
Therefore, even if the clearance sonar
detects a static object and provides a warn-
ing, the Parking Support Brake function (for
static objects) may not start operating.
Static objects not detected by the sen-
■
sors
The following static objects may not be
detected by the sensors.
Objects such as people, cloth and snow,
●
that are difficult for sonic waves to reflect
off of. (In particular, people may also not
be detected depending on the type of
