Servotronic Unit





System Components

The Servotronic unit is speed dependent and is triggered by the electronic speedometer. It is entirely independent of the engine speed:
- A microprocessor evaluates the speed signal and decides the amount of hydraulic power assistance required. This in turn determines the amount of driver effort required.
- The power value is transmitted as impulses to the rotary spool steering valve, via an electro-hydraulic converter.
- The degree of assistance is proportional to the road speed. This means that minimum driver effort is required at parking speed.
- As the road speed increases, the steering characteristic feels more direct (less hydraulic assistance), enabling precise and responsive reactions to steering wheel movement.
