Dynamic Stability Control (DSC)
*
– BMW 325i
The concept
The Dynamic Stability Control (DSC)
maintains vehicle stability, even in crit-
ical driving situations.
maintains vehicle stability, even in crit-
ical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
under- or oversteering, and, as far as is
possible within the laws of physics,
helps keeping the vehicle on a steady
course by reducing engine speed and
brake applications to the individual
wheels.

ADB (Automatic Differential Brake)
relies on selective braking applications
at the drive wheels to furnish the func-
tionality of a conventional limited-slip
differential for enhanced traction in crit-
ical driving conditions such as those
encountered on snow-covered road
surfaces, etc.
