Operation starting conditions

When the PKSB OFF indicator is not illumi-

nated or flashing (

P.233, 370) 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 an obstacle in the traveling direc-

tion 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 obstacle is no longer in the traveling

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 obstacle is no longer in the traveling

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.230).

Therefore, even if the clearance sonar

detects an obstacle and provides a warning,

the Parking Support Brake function (for

static objects) may not start operating.

■

Obstacles not detected by the sensors

The following obstacles 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

clothing they are wearing.)

●

Objects not perpendicular with the

ground, objects not at a right angle to the

traveling direction of the vehicle, uneven

objects or waving objects

●

Low objects

●

Thin objects such as wires, fences, ropes

and signposts

●

Objects that are extremely close to the

bumper

■
