BMW 3: Driving comfort
Adaptive M chassis
Concept
The Adaptive M chassis is a controllable sport chassis/suspension. This system reduces undesirable vehicle motion when using a dynamic driving style or traveling on uneven road surfaces.
This enhances the driving dynamics and driving comfort depending on the road surface condition and driving style.
General information
The system offers several different damping settings.
The damping settings are assigned to the different driving modes of the Driving Dynamics Control.

Performance Control
Performance Control enhances the agility of the vehicle.
To increase maneuverability, wheels are braked individually when a sporty driving style is used.
The resulting braking power is simultaneously largely compensated by an engine intervention.

Flat Tire Monitor FTM
Concept
The system detects tire inflation pressure loss
on the basis of rotation speed differences between
the individual wheels while driving.
In the event of a tire inflation pressure loss, the
diameter and therefore the rotational speed of
the corresponding wheel changes. The difference
will be
DC/DC converter
The DC/DC converter in the Electrical Machine Electronics of the G20 PHEV is
able to adopt the
following operating modes:
Standby (also in the event of a component fault or short circuit, power
electronics off)
Buck mode (energy flow to the low-voltage side, converter adjusts
voltage on
