Abstract

A method for controlling the speed of a vehicle is proposed, where, in the vehicle to be controlled, the yaw rate or rotation rate is measured, in particular to determine the curvature of the vehicle's own travel trajectory, and where, using a proximity sensor or position sensor, at least one vehicle traveling ahead or at least some other object within a sensor's sensing range is detected, particularly with regard to an offset from the travel course of the vehicle to be controlled. From the detection of one or of a plurality of objects, the curvature of the vehicle's own travel trajectory may be corrected with a view to a prediction of an expected curvature from the averaging of the positional changes ascertained at the plurality of the objects.
