Driving Stability Control Systems - BMW X1 Owner's Manual

Driving stability control systems

Vehicle features and
options
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features that are not necessarily
available in your vehicle, for instance, due to the
selected options or country versions. This also
applies to safety-related functions and systems.
When using these functions and systems, the
applicable laws and regulations must be ob‐
served.
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during brak‐
ing.
The vehicle maintains its steering power even
during full brake applications, which increases
the active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically boosts the vehicle braking capabil‐
ity to the furthest possible extent. It reduces the
braking distance to a minimum during an emer‐
gency stop. This system utilizes all of the capa‐
bilities provided by the Antilock Brake System
ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.

Automatic Differential
Brake
The system controls the driving force by auto‐
matic braking intervention on individual wheels.
The function corresponds to a differential lock:
the system detects if a wheel begins to spin, be‐
cause of loose road surface, for instance and au‐
tomatically brakes it.
The driving force is diverted to the wheel with
better traction.
As a result, the engine force is transferred more
efficiently to the wheels during accelerations.
DSC Dynamic Stability
Control
Concept
Within the physical limits, the system helps to
keep the vehicle on a steady course by reducing
engine speed and by applying brakes to the indi‐
vidual wheels.
General information
DSC detects the following unstable driving con‐
ditions, for instance:
▷ Fishtailing, which can lead to oversteering.
▷ Loss of traction of the front wheels, which
can lead to understeering.
Dynamic Traction Control DTC, refer to
page 163, is a version of the DSC where forward
momentum is optimized.
