Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
New Control Units: Notes
Two newly developed control units for dynamic driving systems will also be used in the F01/F02:
- Integrated Chassis Management (ICM) and
- Vertical Dynamics Management (VDM).
Although their names are already familiar from the E70/E71, they differ considerably in their functional range and design.
A multitude of driving dynamics functions is concentrated in these control units.
In addition to central signal provision, the essential functions of the ICM control unit are concerned with longitudinal and lateral dynamics. These include the control function for the new Integral Active Steering, for example.
The vertical dynamics functions on the other hand are incorporated in the VDM control unit: Vertical Dynamics Control in the 2nd generation and Active Roll Stabilization (also: Dynamic Drive).
Although both control units are standard equipment, two expansion stages are available in each case, depending on the options fitted to the vehicle.
