6.2. Dynamic Stability Control
Dynamic Stability Control is standard in all BMW vehicles.
The DSC prevents spinning of the drive wheels when starting up and when accelerating.
The DSC also identifies unstable driving conditions, such as oversteer or understeer. The DSC helps to keep the vehicle on a safe course by applying brake interventions on the individual wheels (within the physical limits) and by reducing the engine output in order to control wheel spin and maintain traction.
Note. It always remains the responsibility of the driver to adapt his or her driving style. Even with the DSC, the laws of physics still apply. Always Drive Safely!
The DSC system control unit is attached to a hydraulic valve block and it includes many individual functions that are listed in the following table.
| Function | Subfunction | Description |
|---|---|---|
| ABS | Antilock Brake System | |
| EBV | Electronic brake force distribution | |
| CBC | Cornering Brake Control | |
| DBC | Dynamic Brake Control | |
| ASC | Automatic Stability Control | |
| MMR | Engine torque control | |
| MSR | Engine drag torque control | |
| BMR | Brake torque control | |
| DSC | Dynamic Stability Control | |
| GMR | Yaw moment control | |
| SDR | Thrust differential control | |
| DTC | Dynamic Traction Control |

EXPLANATION CHART
The F10 uses Vertical Dynamics Management (VDM) with Electronic Damper Control (EDC).
Beginning with the F01/F02, the EDC is also called VDC (Vertical Dynamic Control) and is a function of the VDM.
The VDM was introduced with the E70/E71, enhanced for the F01/F02 and now further developed for the F10.
With Vertical Dynamics Control (VDC), independent electronic damper control for each wheel is possible, whereas EDC is only capable of front to rear adjustments.
During this process, the servomotors and the sensors on the shock absorbers, known as satellites, are connected to the VDM control unit via FlexRay.
The VDC and the Dynamic Drive (ARS for the vehicles BMW 535i, BMW 550i) are available only in combination as Adaptive Drive (option 2VA). EDC can only be ordered individually as optional equipment (option 223) on the BMW 528i.
