Servotronic
E83
Introduction
The Servotronic does not regulate the steering force support in a conventional way by using the engine speed, rather
it is dependant upon the car's road speed. The Servotronic regulates the hydraulic pressure in the power-steering
pump. Adaptation of the hydraulic pressure to the car's road speed has the effect of:
-
High steering force support at low road speeds
-
Minimum steering force support at high road speeds
This means that minimum force is required for steering force at slow road speeds. As the road speed increases the
steering force support is continuously reduced. Contact to the road surface therefore becomes more direct and
steering is more precise. Consequently, steering is very comfortable and manoeuvrability is maximised, for instance
when parking and manoeuvring at slow speeds.
[system overview ...]
New: In E83 the Servotronic is integrated in its own control unit.
The Servotronic is available as special equipment (option 216).
Brief description of components
The following control units are involved in the Servotronic:
-
Servotronic control unit (SVT)
The SVT control unit specifies the nominal values for controlling the Servotronic valve (hydraulic pressure). The
SVT control unit is connected to the PT-CAN (powertrain CAN) and K-Bus (body bus).
