As is already familiar from the G12, the G30 does not have Integrated Chassis
Management (ICM). The
ICM functions are distributed between the optional equipment system (SAS) and
the Dynamic Stability
Control (DSC).
It has been possible to further improve the driving dynamics in the G30 by
selective use of various
control functions. This is particularly keenly felt in relation to the steering
behavior, the traction and the
vehicle's stability.
The control units necessary to meet the requirements on driving dynamics are
located on the FlexRay
bus. This allows them to quickly exchange their information with each other and
react to events.
The following actuators are activated as needed:
- Rear axle slip angle control HSR (optional equipment)
- Electronic Power Steering EPS (standard equipment)
- DME engine control unit
- VTG transfer case (optional equipment)
- Electric active roll stabilization at the front and rear (EARSV/EARSH)
(optional equipment)
- Electronic Damper Control (EDC) (optional equipment)
The tables below provide an overview of the various control functions and
their effects on the
drivability.

Alongside the Vertical Dynamics Platform (VDP) control unit, the Dynamic
Stability Control (DSC)
represents the core element of the driving dynamics control systems used to
increase active safety. I
The G30 has Electronic Power Steering (EPS) in the following different
versions:
Standard steering 12 V
Integral Active Steering 12 V
Integral Active Steering 24 V

Air Breathers are also used on the front fenders of the G30. The Air Breather
is an air outlet behind the
front wheel, which diverts the air flowing into the rear region of the wheel
well in a controlled manner
towards the fender in order to reduce turbulences in the wheel well area. As a
result,

Blind spot collision warning detects vehicles in
the blind spot or vehicles approaching from behind
in the adjacent lane. A warning is issued in
various gradations in these situations.
