Audi pre sense front emergency

In case of an emergency stop,
Audi pre sense front calculates
whether the driver brakes
sufficiently to prevent a collision. If
this is not the case, depending on
the situation the necessary
braking performance is increased
up to a full deceleration.

addition, the triggering algorithms
for the hydraulic brake assistant
are changed. As a result of this
action, the response time of the
brake is very fast. If the vehicle
continues turning and rolls/pulls
away now, Audi pre sense front
detects this with the speed
sensors of the ABS control
module J104.
In this case, Audi pre sense front
would initiate an automatic
emergency braking by the ABS
control module J104 so that the
vehicle stops in its own lane. The
driver is notified visually and
acoustically that the vehicle is
braking automatically.
Intervention of emergency steer

vehicle after a warning jolt, the
evasion assistant supports him
with steering torque if necessary.

If the own vehicle moves within

assistant attempts to guide the
vehicle along the evasion line by

limits, a loss of control can be
prevented when evading an
obstacle.
