Conditions for Airbag Activation
If the control module detects a high collision force
and the seat is more than 30% from its front
position, the front airbags will be inflated in two
stages with a 5 to 20 ms delay between the
deployment of the two stages. If the collision
force is low, only stage 1 will be activated. If the
seat position sensor indicates that the seat is less
than 30% from its front position, stage 1 will be
activated. The front airbags will be activated
earlier if the seat-belt buckle is not locked.
A collision on one side of the car will activate the
side airbag only on the side where the collision
has taken place.
In situations where the front airbags are activated
to stage 1 only, there will be a safety activation of
stage 2 after 100 ms. This will disarm the airbag
so that there is no charge left to activate after the
collision.
The seat-belt tensioners will not be activated if
the seat-belt buckle is not locked.
Reserve power supply
The control module has an integrated reserve
power supply that supplies it with current for
150 ms after the normal power supply has
ceased.
This function has three capacitors that maintain
the level of current to the system and enable the
front airbags to be activated for 150 ms. The side
impact sensors are then turned off to save
energy. Bus communication continues during this
time.
