BMW 7 Series: Introduction

Refinements in Detail

The longitudinal dynamics systems described in this document comprise the following:

• Dynamic stability control (DSC) and
• Electromechanical parking brake (EMF)

Both DSC and EMF are standard equipment on all F01/F02 models. Thus BMW has consistently continued the standards set by the E65/E66 and the E70/E71. Both systems are based on the technology used on the E70/E71.

However, many specific details have had to be changed. Those changes were essential to ensure that DSC and EMF could be seamlessly integrated in the new dynamic handling system complex on the F01/F02.

As far as the Dynamic Stability Control was concerned, co-ordination with the central dynamic handling controller on the Integrated Chassis Management (ICM) master control unit had to be taken into consideration.

And the new "dynamic handling control" function also affects the way the DSC operates. The thresholds and the nature of the DSC interventions have to be adapted to suit the setting selected.

Thus the DSC doesn't simply contain a setting that suits a luxury-class vehicle such as the F01/F02. Instead, several different settings have been developed which correspond to the characteristics of the various dynamic handling control settings.

In addition to adaptation to handling characteristics, there are numerous other changes to the Dynamic Stability Control on the F01/F02 which relate to location, display features, fault diagnosis and repair.

Starting from the basis of the system on the E70/E71, the electromechanical parking brake has been adapted to the requirements of the F01/F02. That includes such things as location and attachment to the vehicle. In addition, design enhancements have been introduced to make the EMF actuator quieter in operation.

This reference document sets out in detail all the changes to the Dynamic Stability Control and electromechanical parking brake that are specific to the F01/F02.

However, features of the two systems that are familiar from the E70/E71 are not repeated in this document.

Those details can be found in the respective training manuals.
