Dynamic Stability Control

As standard, the new BMW X3 is equipped with Dynamic Stability Control (DSC). The DSC System relies on interaction with the central driving dynamics control in the Integrated Chassis Management (ICM) and control of the transfer case (VTG). The ICM supplies the setpoint data for DSC control operation. The VTG is controlled to modulate distribution of drive torque between the front and rear axles. This allows the VTG to support the DSC control operation.

The drive dynamic control switch also influences the operating principle of the DSC. Depending on the selected stage (NORMAL, SPORT+ identical to DTC), the threshold values and characteristics of the DSC interventions also have to be adapted. In addition to the matching of the threshold values, there are still additional changes to the dynamic stability control which affect the installation location, display scopes as well as the diagnosis and repair.
