BMW E46 325i Touring: 6 SI Techniques, 34 Brakes, 2 SBT DSC Mk60 E85
The DSC dynamic driving system is a lateral and transverse dynamic control system that actively intervenes in the
actions of the brakes and engine control systems. DSC comprises a number of functions:

Anti-lock braking system ABS
ABS prevents the wheels from locking when the brakes are applied.
Advantage: short braking distances, the vehicle remains stable.
Brake pressure is regulated at all wheels to ensure that each wheel runs in the best possible slip range. When
this happens, slip is controlled so that the maximum possible braking and lateral stability forces can be
transmitted.
Electronic brake force distribution EBV
EBV is a component of ABS and controls the brake force distribution between the front and rear wheels.
Advantage: regardless of the load state of the vehicle, the best possible braking distance is achieved while
driving stability is maintained.
Modern vehicles have relatively large brakes on the rear axle to shorten braking distances. To prevent the rear
wheels from being overbraked in certain driving situations, EBV permanently monitors the slip values. EBV
controls rear axle slip in dependence of the front axle.
Cornering brake control CBC
CBC is an extension of ABS. CBC enhances driving stability if the brakes are applied when cornering.
Advantage: if the brakes are applied in a corner, optimum brake force distribution ensures the best possible
tracking stability.
The shifting of wheel loads when cornering (even if brakes are only applied lightly) can adversely affect driving
stability. If required, CBC generates a stabilising load moment when the brakes are applied lightly outside the
