In the following example vehicle (E) is approaching another
vehicle(A). Audipresensefront has detected a critical situation
based on the information provided by the ACC sensors or the front
camera.
The following action was taken by Audipresensefront:
• Audible and visual early warnings
• Pre-charging of the brake system
• Adaptation of hydraulic brake assist and the acute warning
(warning jerk), refer to functionA on page26.
If the driver (E) takes action to evade vehicle (A) after the acute
warning (brake jerk) has been given, evasion assist provides assist-
ance if needed by producing additional steering torque.
Audipresensefront computes a suitable evasion line based on
various items of information, such as one's own speed and the lane
in which the vehicle ahead in driving.
If vehicle (E) deviates too far from the evasion line, but is still
within certain bounds, evasion assist will try to guide the vehicle

to help the driver steer past the obstacle. This can help to prevent
loss of vehicle control while taking evasion action, provided this is
within the physical limitations of the system.
