Depending on the accident situation, the post-col-
lision brake can minimise the se verity of a fur ther
collision or evenavo id it.
If an accident is de tected, the post-collision brake
can implement automatic braking. When theve hi-
cle has come toa standstill, the electric parking
brake is automatically applied. The driver can cancel automatic braking
bytaking
