DSC Functions: Overview

The Dynamic Stability Control on the F01/F02 (DSC F0x) essentially incorporates the same functions as on the E70/E71 (DSC E7x).

As the DSC F0x is based on the same highly advanced technology as the DSC E7x, all DSC functions on the F01/F02 achieve outstanding performance in terms of:

• dynamic response (brake pressure can be generated extremely quickly).
• control precision (brake pressure can be adjusted extremely precisely and without significant fluctuation).
• noise emission (operation of the valves and the hydraulic pump is quieter than the previous generations).
• tactile response (unpleasant feedback from the brake pedal has been substantially reduced, e. g. pedal vibration during brake modulation).

Differences between the DSC functions on the E70/E71 and F01/F02 arise from the different drivetrain configurations (4-wheel drive/rear-wheel drive). Therefore, the DSC F0x does not include the "Hill Descent Control (HDC)" function specific to 4-wheel drive vehicles.

Instead of the 4-wheel-drive version of the automatic differential brake (ADB-X), the DSC F0x uses the version for vehicles with rear-wheel drive (ADB).

A new subfunction of the ADB is that traction-control brake modulation is available even when the DSC is switched off. This subfunction is called "Electronic Differential Lock Control" and is described in one of the subsections below.
