摘要： A method for creating or augmenting a map for a motor vehicle, wherein the motor vehicle establishes its location in a surrounding environment by comparing environment data acquired by at least one sensor with map data stored in the map. The method provides a base map of a surrounding environment of the motor vehicle; provides at least one base segment, wherein the at least one base segment has at least one characteristic feature; and creates or augments the map by generating map data, wherein the map data is generated by a map creation unit by assigning the at least one provided base segment to an associated position in the provided base map. Also disclosed is a corresponding device.

摘要： A method for determining a location of a motor vehicle, wherein a respective rotational position signal is received from a respective wheel sensor of at least one wheel, and a steering angle signal is received from a steering angle sensor of a steering device, and a wheel-based location estimation is determined, the respective rotational position signal and geometric data of the at least one wheel. A respective relative location of the motor vehicle with respect to at least one object arranged in the surroundings is detected, and a respective relative change in location with respect to the at least one object is determined during a movement of the motor vehicle, and a surroundings-based location estimation is determined, and a combined location estimation of the location is determined from the wheel-based and the surroundings-based location estimation.
