Dynamic Stability Control (DSC): History
The history of wheel slip control systems used in BMWs is covered in the Chassis Dynamics course (ST056). DSC III was technically modified (deletion of the pre-charging unit), the functions were extended and renamed DSC 5.3. The DSC 5.3 was further developed into DSC 5.7 by adding these functions:
- Dynamic Brake Control (DBC)
- Dynamic Brake Support (DBS)
- Maximum Brake Support (MBS)
These functions have been used in Bosch systems since 1999. For the E65, DSC 5.7 is further developed and expanded to include the software functions to achieve improved system operation:
- FBS Fading Brake Support
- FLR Driving Performance Control
- Parking Brake (hydraulic service brakes)
- DTC Dynamic Traction Control
In addition, the evaluation of the 2-stage brake lining wear sensors is integrated in the DSC control module. The DSC system is connected to the PT-CAN Bus.
