Through control state “warning
phase 1” and “warning phase 2”,
the system determines if the
driver is aware and responsive
while outputting a warning and
controlling the vehicle speed. If
the system determines the
driver is not responsive, it will
operate in control state “deceler-
ation stop phase” and “stop hold
phase” and decelerate and stop
the vehicle. It will then operate
continuously in “stop hold
phase”.
■ Operating conditions
This system operates when all of
the following conditions are met:
● When the LTA is on
● When the vehicle speed is
approximately 30 mph (50 km/h)
or more
■ Operation cancelation condi-
tions
In the following situations, system
operation will be canceled:
● When LTA control has been can-
celed (the LTA switch has been
pressed, etc.)
● When the dynamic radar cruise
control has been canceled
● When driver operations are
detected (the steering wheel is
held, the brake pedal, accelerator
pedal, parking brake, hazard light
switch, or turn signal lever is oper-
ated)
● When the driving assist switch is
pressed while in the stop and hold
phase
● When the engine switch has been
turned from ON to off
● Situations in which some or all of
the functions of the system cannot
operate:

■ LTA control when operation is
canceled
When emergency driving stop sys-
tem operation is canceled, LTA con-
trol may also be canceled.
If driving operations are not
detected after the hands off
steering wheel warning oper-
ates, a buzzer will sound inter-
mittently and a message will be
displayed to warn the driver, and
the system will judge if the driver
is responsive or not. If driving
operations, such as holding the
steering wheel, are not per-
formed within a certain amount
of time, the system will enter
warning phase 2.
After entering warning phase 2,
a buzzer will sound in short
intervals and a message will be
displayed to warn the driver, and
the vehicle will slowly deceler-
ate. If driving operations, such
as holding the steering wheel,
are not performed within a cer-
tain amount of time, the system
will determine that the driver is
not responsive and enter the
deceleration stop phase.
The audio system will be muted
until the driver becomes respon-
sive.
