Driver Behavior Acceleration

Rapid acceleration events can be triggered when one of four available thresholds are
exceeded as determined by the accelerometer in milli-Gs (e.g., 0.75) for a defined period of
time in seconds (e.g., 30 seconds). The event will clear if the acceleration falls below the
threshold for a defined period of time. The command may also be configured to clear the
event if it persists beyond a maximum duration.
The following AT Command example sets the rapid acceleration threshold #1 to .2G. If this
threshold is exceeded for 1 second, then an input event is triggered. Keeping the acceleration
of the vehicle below this threshold for 30 seconds will clear this event. There is no maximum
duration set in this example.
AT$DVBACL=1,200,1,30,0

Driver Behavior Deceleration (Harsh Braking)

Rapid deceleration events can be triggered when one of four available deceleration
thresholds are exceeded as determined by the accelerometer in milli-Gs (e.g., 1.0) for a
defined period of time in seconds (30 seconds). The command may also be configured to
clear the event if it persists beyond a maximum duration.
The following AT Command example sets the rapid deceleration threshold #1 to .5Gs. If this
threshold is exceeded for 1 second, then an input event is triggered. Keeping the deceleration
below this threshold for 30 seconds will clear this event. The event will also clear if the
threshold is exceeded for a duration of 10 seconds.
AT$DVBDCL=1,500,1,3,10

Motion Detection

Motion alerts for vehicles can be configured to communicate that a vehicle is being towed.
Motion detection, based on measuring movement via the accelerometer, occurs when the
vehicle ignition is off and the vehicle is stationary.
A motion alert is triggered when motion defined in milli-Gs is detected for a defined period of
time.
