Abstract

A control device for a land vehicle is described. The control device is set up to control at least one actuator of the land vehicle on the basis of an avoidance trajectory calculated by the control device in order to support a driver of the land vehicle during an evasive maneuver. The control device is also set up to receive sensor signals of at least one sensor; to generate an environmental model from the received sensor signals; to determine the position of an object relative to a current position of the land vehicle in the generated environmental model; and to calculate a preliminary avoidance trajectory. In the calculation of the preliminary avoidance trajectory, the current position of the land vehicle in the generated environmental model constitutes the starting point of the preliminary avoidance trajectory. A preliminary end point of the preliminary avoidance trajectory is determined on the basis of the determined position of the object. To determine the parameters of the preliminary avoidance trajectory, at least the coordinates of the starting point and of the preliminary end point are used.
