Toyota Safety Sense 4.0
Emergency Driving Stop SystemEmergency Driving Stop SystemThe emergency driving stop system is a system which automatically decelerates and
stops the vehicle within its lane if the driver becomes unable to continue driving
the vehicle, such as if they have suffered a medical emergency, etc.During LTA (Lane Tracing Assist) operates, if the system does not detect driving operations,
such as if the driver is not holding the steering wheel, and determines the driver
is not responsive, the vehicle will be decelerated and stopped within its current
lane to help avoid a collision or reduce the impact of a collision.The vehicle will also decelerate/stop during the Traffic Jam Assist (if equipped)
operates, when no driver’s response to the vehicle’s warning to hold the steering
wheel is detected. Warning:For safe useDriving safely is solely the responsibility of the driver. Pay careful attention to
the surrounding conditions in order to ensure safe driving. The emergency driving
stop system is designed to provide support in an emergency where it is difficult for
the driver to continue driving, such as if they have had a medical emergency. It is
not designed to support driving while drowsy or in poor physical health, or inattentive
driving.Although the emergency driving stop system is designed to decelerate the vehicle within
its lane to help avoid or help reduce the impact of a collision if the system determines
that it is difficult for the driver to continue driving, its effectiveness may change
according to various conditions. Therefore, it may not always be able to achieve the
same level of performance. Also, if the operating conditions are not met, this function
will not operate.After the emergency driving stop system operates, if driving becomes possible again,
immediately begin driving again or, if necessary, park the vehicle on the shoulder
of the road and set a warning reflector and flare to warn other drivers of your stopped
vehicle.After this system operates, passengers should attend to the driver as necessary and
take appropriate hazard prevention measures, such as moving to a place where safety
can be ensured, such as the shoulder of the road or behind a guardrail.This system detects the condition of the driver through the operation of the steering
wheel. This system may operate if the driver is aware but intentionally and continuously
does not operate the vehicle. Also, the system may not operate if it cannot determine
that the driver is not responsive, such as if they are leaning on the steering wheel.Summary of the systemOperation of this system is separated into 3 control states. Through control state
warning phase, 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 “deceleration stop phase” and “stop
hold phase” and decelerate and stop the vehicle. It will then operate continuously
in “stop hold phase”.Note:Operating conditionsThis system operates when all of the following conditions are met:When LTA and dynamic radar cruise control are activatedOr during the Traffic Jam Assist (if equipped) operates When the vehicle speed is approximately 22 mph (35 km/h) or moreDuring the Traffic Jam Assist operates (if equipped), the system may operate at below
22 mph (35 km/h). Operation cancelation conditionsIn the following situations, system operation will be canceled:When driver operation is detected (emergency flasher switch is operated, the steering
wheel and the pedal [brake pedal or accelerator pedal] are operated.)When the shift position is set to P while in the stop hold phaseWhen the parking brake is operated while in the stop hold phaseWhen the brake pedal is operated and the parking brake is canceled while in the stop
hold phaseWhen the power switch has been turned to OFFAccelerator pedal operation while the system is activeAcceleration cannot be performed by operating the accelerator pedal while the system
is activeLTA and dynamic radar cruise control when operation is canceledWhen emergency driving stop system operation is canceled, LTA and dynamic radar cruise
control are canceled.Warning phaseAfter entering the warning phase, a buzzer will sound in short intervals and a message
will be displayed to warn the driver, and the vehicle will slowly decelerate. If driving
operations such as the steering wheel and pedal operation are not performed within
a certain amount of time, the system will determine that the driver is not responsive
and enter the deceleration stop phase.When the vehicle is decelerating, the brake lights may illuminate, depending on the
road conditions, etc.Deceleration stop phaseAfter the system determines that the driver is not responsive, it warns the driver
by continuously sounding a buzzer and displaying a message, and then decelerates the
vehicle to a stop. After the vehicle comes to a stop, the system will enter the stop
hold phase.Stop hold phaseAfter the vehicle is stopped, the parking brake will be applied automatically. After
entering the stop hold phase, the buzzer will continue sounding continuously, and
the emergency flashers (hazard lights) will flash to warn other drivers of the emergency.
Additionally, emergency rescue and assistance requests for the driver will be made
automatically through the Safety Connect services (only for subscribers).Note:Automatic connection to Safety Connect servicesAfter automatically connecting to Safety Connect services, if there is no response
from inside the vehicle to a call from the operator, emergency services or the police
will be notified for rescue and assistance.Restricted functions after the operation is canceledAfter shifting to the deceleration stop phase, the following functions will not be
available until the hybrid system is re-started even though the emergency driving
stop system is canceled: LTALCA (if equipped)Traffic Jam Assist (if equipped)Warning:Automatic connection to Safety ConnectAn automatic connection to Safety Connect services is only performed when the user
is in the Safety Connect communication area and has a Safety Connect contract. If
you are outside the Safety Connect communication area, do not have a Safety Connect
contract, or if the contract has not been renewed, the connection will not be made,
and no notifications will be sent to the police or emergency services. Please confirm
your communication area and your Safety Connect contract in advance before using the
system.
