Abstract
A vehicle includes at least one of (i) an undercarriage and an upper carriage arranged rotatably about a vertical axis with respect to the undercarriage and (ii) a leverage means arranged pivotably about a horizontal axis with respect to the upper carriage, wherein a sensor system is provided for monitoring at least one stability criterion with respect of a tilt movement of the vehicle, and wherein a control unit is coupled to the sensor system for automatically initiating an action and/or performing an action for stabilizing the vehicle depending on the at least one stability criterion. The risk of an unexpected tilting of the vehicle can be reduced.
