Active Emergency Braking

Active emergency braking can help to
reduce the damage and injury from
crashes with vehicles and obstacles
directly ahead, when a collision can
no longer be avoided either by
manual braking or by steering. Before
the active emergency braking
applies, the driver is warned by the
forward collision alert 3 230.
The feature uses various inputs (e.g.
radar sensor, brake pressure, vehicle
speed) to calculate the probability of
a frontal collision.
Active emergency braking operates
automatically above walking speed,
provided that Auto collision
preparation setting is not deactivated
in the vehicle personalisation menu
3 124.
The system includes:
● brake preparation system
● emergency automatic braking
● forward looking brake assist
9 Warning
This system is not intended to
replace the driver responsibility of
driving the vehicle and looking
ahead. Its function is limited to
supplemental use only. The driver
shall continue to apply the brake
pedal as the driving situation
dictates.
Brake preparation system
When approaching a vehicle ahead
so quickly that a collision is likely, the
brake preparation system slightly
pressurises the brakes. This reduces
the response time, when a manual or
automatic braking is requested.
The brake system is prepared so that
braking can occur more rapidly.
Emergency automatic braking
After the brake preparation and just
before the imminent collision, this
function automatically applies limited
braking to reduce the impact speed of
the collision.
Forward looking brake assist
In addition to brake preparation
system and emergency automatic
braking, the forward looking brake
assist function makes the brake assist
more sensitive. In this way,
depressing the brake pedal slightly
results immediately in a strong
braking. This function helps the driver
brake quicker and stronger before the
imminent collision.
