Abstract
A device for operating a chassis of a two-track vehicle, in which each vehicle wheel is assigned a suspension spring, which carries the static body weight of the vehicle, and a vertical dynamics actuator, which is actuatable by a vertical dynamics control unit, having a tipping detection function which detects a tipping situation with a roll-over risk in which there is a danger that the vehicle will tip sideways on a transversely inclined roadway. When a roll-over risk is detected, the vertical dynamics control unit actuates the vertical dynamics actuators to avoid roll-over.

A device for operating a chassis of a two-track vehicle, in which each vehicle wheel is assigned a suspension spring, which carries the static body weight of the vehicle, and a vertical dynamics actuator, which is actuatable by a vertical dynamics control unit, having a tipping detection function which detects a tipping situation with a roll-over risk in which there is a danger that the vehicle will tip sideways on a transversely inclined roadway, wherein when a roll-over risk is detected, the vertical dynamics control unit actuates the vertical dynamics actuators to lower the vehicle center of gravity and/or to reduce a roll angle on an uphill side until a predetermined body position of the vehicle is reached, wherein if a tipping situation exists, the vertical dynamics control unit automatically actuates the vertical dynamics actuators, and/or the tipping protection function is assigned a display means which triggers a warning message for the user if a critical tipping situation is detected, and/or the device has an input means operable by the user by which the vertical dynamics control device is manually actuatable by the user in order to achieve the predetermined position.
