A control system is suitable for use in a motor vehicle and is configured and intended for using information concerning objects and/or driving-related information about another motor vehicle in order to distinguish real objects in the surroundings of the motor vehicle from erroneously detected objects, based on surroundings data that are obtained from at least one surroundings sensor situated on the motor vehicle and provided to the control system. Based on these surroundings data, an object in the surroundings of the motor vehicle is detected, and a distance and/or a relative speed and/or an angle between the motor vehicle and the object are/is determined. The object is then classified as an actually existing object or as an erroneously detected object, based on the determined distance and/or based on the determined relative speed and/or based on the determined angle.
