DISTRONIC PLUS
DISTRONIC PLUS is an extension of the DISTRONIC
adaptive cruise control.
DISTRONIC PLUS also incorporates a short range
radar with two new sensors at the front, which now
covers the vehicle speed range from 0 to 30 km / h
within a detection radius of 30 m.
This allows the distance to be regulated in the speed
range from 0 to 200 km / h and can also be used to
handle stop-and-go traffic.
If the lane ahead of the vehicle is clear, DISTRONIC
PLUS regulates the set target speed in the same way
as a conventional cruise control. As the car
approaches a preceding vehicle, the speed is reduced
in order to maintain the distance set by the driver.
BAS PLUS
BAS PLUS is coupled with the sensor system of
DISTRONIC PLUS. This makes BAS PLUS a predictive
brake assist system, the activation strategy of which,
in addition to the analysis of the driver's brake appli-
cation, can also call on an evaluation of the ambient
situation (detection of preceding objects) in front of
the vehicle.
The aim of the Brake Assist System in the event of an
imminent collision is to avoid a crash or, if this is not
successful, to significantly reduce the effects of the
accident.
BAS PLUS is only triggered when the driver applies the
brakes and the system detects the danger of an immi-
nent collision. If the reaction speed and brake force
are insufficient, the BAS PLUS Brake Assist System
assists the driver's braking action. It can apply full
braking until the vehicle comes to a stop. The brake
application is intensified by the system according to
the situation.
By not using full brake force at once, the stopping
distance for following vehicles is lengthened and the
risk of a collision is reduced.
