2. FCW(Forward Collision Warning)
<Function>
This warning is issued in the early stages of a
potentially dangerous situation, caused by such
circumstances as driver’s inattention/daydreaming, or
the sudden change in movement of a preceding
vehicle, which may result in a collision.
FCW is based on calculation of Time To
Collision(TTC)
with the vehicle ahead, taking into account the
distance from it and the relative traveling speed.
