EmergencyDrivingStopSystem
EmergencyDrivingStopSystem
The 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) control, 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.
WARNING

Summaryofthesystem
Operation of this system is separated into 4 control states. 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 "deceleration stop phase" and "stop hold phase" and decelerate andstop the vehicle. It will then operate continuously in "stop hold phase".
INFORMATION

If driving operations, such as holding the steering wheel, 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.
The audio system will be muted until the driver becomes responsive.
When the vehicle is decelerating, the brake lights may illuminate, depending on the road
conditions, etc.
Decelerationstopphase
After entering the deceleration stop phase, a buzzer will sound continuously and a
message will be displayed to warn the driver, and the vehicle will slowly decelerate and stop. After the vehicle stops, the system will enter the stop and hold phase.
Stopholdphase
After the vehicle is stopped, the parking brake will be applied automatically. After
entering the stop and hold phase, the buzzer will continue sounding continuously
and the emergency flashers (hazard lights) will flash to warn other drivers of the emergency.
