Z Series E85 Z4 3.0Si (N52) ROADST
-
Brake light switch
Together with the signals from the brake pressure sensors, braking actions are recognised.
-
Parking brake warning switch
DSC will recognise skidding that has been deliberately initiated by the driver. Regulation will not take place.
Reason: a handbrake turn should remain technically possible.
DSC system functions
DSC uses brake actions and engine intervention to influence longitudinal and lateral dynamics.
DSC comprises numerous functions.
Functions familiar from current DSC:
-
ABS: Anti-lock braking system
-
EBV: Electronic brake force distribution
-
CBC: Cornering Brake Control
-
ASC: Automatic stability control
-
DTC: Dynamic traction control
-
MSR: Engine drag torque control
-
DBC: Dynamic brake control
-
RPA: Run Flat Indicator (not a driving dynamic control function)
-
CBS: Condition Based Service (not a driving dynamic control function)
New functions for DSC Mk60E5:
-
Brake Standby through pre-tensioning of the brakes in an emergency
-
Brake disc drying on wet roads
-
Fading compensation
-
Soft stop when braking to standstill (only E87 with 6-cylinder engine, E90, E91, E92, E93)
-
Start-off assistant
-
Adapted interface for cruise control with brake function (only E90, E91, E92, E93)
-
Adapted interface for active cruise control (only E90, E91, E92, E93)
-
Yaw-moment compensation via active steering (only E87 with 6-cylinder engine, E90, E91, E92, E93)
ABS: Anti-lock braking system
ABS prevents the wheels from locking when the brakes are applied.
Advantage: Optimum utilisation of road surface friction - the vehicle remains stable and steerable.
Brake pressure is regulated at all wheels to ensure that each wheel runs with optimum slip.
When this happens, slip is controlled so that the maximum possible braking and lateral stability forces can be
transmitted.
EBV: Electronic brake force distribution
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 slip. EBV controls rear
