Abstract: A method for regulating an active chassis of a motor vehicle as a function of road elevation profile data which lie within a prognosis for a trajectory of the motor vehicle. The prognosis of the trajectory is calculated by a mathematical model at least on the basis of steering angle data of a steering angle sensor of the motor vehicle. The prognosis of the trajectory is assigned to the road elevation profile data detected by at least one environmental sensor. Based on the prognosis, at least one actuator of the active chassis is controlled, and the prognosis of the trajectory is then used exclusively to control the active chassis when the trajectory lies in an area that was classified as navigable based on the environmental data that was detected by at least one environment sensor.
