Servotronic (SVT): Notes

Servotronic is a transverse dynamics system. Servotronic has the task of continuously adapting the steering servo depending on the driving speed and steering angle. For this purpose, Servotronic correspondingly controls the electrical current of the Servotronic valve so that the flow of hydraulic fluid assists steering to a greater or lesser extent. The current steering angle is additionally taken into account in order to better meter the steering assistance based on the steering angle. The steering servo is determined with the aid of characteristic maps and decreases with increasing driving speed, thus increasing the amount of steering torque required.

The Servotronic can be realized by different control units:

• Control unit for Servotronic (SVT), e.g. RR4 and F15
• Integrated Chassis Management (ICM), 1st generation only, e.g. F01
