1. A method for providing operating data for an at least semi-automated vehicle, comprising the following steps:
locally storing in the vehicle a low-resolution digital localization map having map data at a first data resolution;
sensorially detecting surroundings data using a surroundings sensor system of the vehicle;
based on the sensorially detected surroundings data in view of the low-resolution digital localization map, over time making identifications, by the vehicle, of the vehicle entering respective ones of predefined mapping regions that are each drawn about a respective one of a plurality of lane change zones, wherein the lane change zones are each a respective area in which a number of lanes that are available to be driven changes;
responding, by the vehicle, to each of the identifications by responsively requesting from a cloud respective cloud map data for increasing in the vehicle the map data for the respective identified mapping region to a second data resolution that is higher than the first resolution with respect to feature density, wherein, for each of the requests, the vehicle conveys a respective portion of the sensorially detected surroundings data to the cloud;
for each of the requests, the vehicle responsively receiving from the cloud the respective cloud map data; and
for each of one or more of the lane change zones:
performing, by the vehicle, a refined localization of the vehicle according to the map data in the vehicle at the second data resolution;
ascertaining, by the vehicle, the operating data for use in a cooperative driving maneuver of the vehicle with at least one further road user according to the refined localization and the sensorially detected surroundings data; and
initiating, by the vehicle, the cooperative driving maneuver using the ascertained operating data.
