SLC (suspension and level control) enables remote control of up to four cylinders for axle suspension. Various topologies of single-axle suspensions or even floating axle suspensions can be realized in different configurations. Ring-side closed-loop pressure control to adjust the suspension characteristics and relationships with engine speed and/or vehicle speed can also be implemented optionally.
Various modes are available for leveling the vehicle: in “Automatic” mode, the controller regulates the strut positions of all cylinders in a parameterized target level range. In “Manual” mode, on the other hand, the travel position can be moved to manually. The entire vehicle can thus be raised or lowered. It is also optionally possible to lift or lower an individual axle pair. The “Lock” function serves to prevent a suspension movement during travel and/or loading.
In addition to sensor specifications, the limits of the travel level, controller characteristics and the relevant geometry-related parameters of the system can also be adjusted.
