1. A method for acquiring transverse-position information of a motor vehicle on a roadway wherein radar data describing at least part of the roadway is acquired by at least one radar sensor of the motor vehicle, environmental features describing the location of a roadway boundary are detected and localized in the radar data by evaluation, from these, a course of the roadway boundaries of the roadway and lateral distances of the motor vehicle with respect to the roadway boundaries are determined, and the transverse-position information is determined as, or as a function of, the lateral distances of the motor vehicle from the roadway boundaries, wherein a radar sensor with a semiconductor chip implementing the radar transceiver is used as the at least one radar sensor, and, as environment features, a transition from the road surface to another surface is detected and localized, wherein, as transverse-position information, a lane assignment of the motor vehicle is determined, taking into additional consideration further information describing the number of traffic lanes of the roadway, wherein roadway division information derived from digital map data and including section information describing the presence and/or the width and/or the location of a part of the roadway not used as a traffic lane is taken into consideration as additional information.
