A method for locating and further developing a digital map by a motor vehicle; localization device

摘要

The invention relates to a method for locating and further developing a digital map (1) by a motor vehicle (2). In order to enable resource-saving localization of the motor vehicle based on a digital map and to further develop the digital map, the following steps are provided: - Receiving a digital sub-map (4) of a plurality of sub-maps (4) of the digital map (1) by the motor vehicle (2) from a database (7), wherein the digital map (1) according to a predetermined division rule in the plurality of digital sub-maps (4) is divided, and wherein the digital sub-map (4) an environment (U) of the motor vehicle (2 ), - detecting an image (3) of the environment (U) of the motor vehicle (2) by means of a sensor arrangement (51) of the motor vehicle (2), - locating the motor vehicle (2) in the environment (U) by comparing the received digital Partial map (4) with the image (3) of the environment (U) of the motor vehicle (2), - further developing the digital sub-map (4) based on the image (3) of the environment (U) of the motor vehicle (2), - transmission n the further developed digital sub-map (5) and / or the image (3) of the environment (U) to the database (7) for further developing the digital map (1).
