A first card and / or a highly accurate card means a digital card which is in the form of (card) data values on a storage medium. By way of example, the first and / or high-precision card is designed such that one or more card layers are covered, wherein one card layer

For example, a map from a bird's eye view (history and position of streets, buildings, landscape features, etc.) shows. This corresponds for example to a map of a navigation system. Another card layer includes, for example, a

Radar map, wherein the environmental characteristics, which are covered by the radar map, are stored with a radar signature. A further map layer comprises, for example, a lid map, wherein the environmental features, which are covered by the lid map, are deposited with a lidar signature.

The first and / or the highly accurate map are in particular designed such that they are suitable for the navigation of a vehicle, in particular of an automated vehicle. These include the individual card layers, for example

Environmental features with a GPS position, this position is known with high accuracy. The environmental features represent the environment (of the mobile device and / or the automated vehicle), for example in the form of buildings and / or landscape features (lakes, rivers, mountains, forests, etc.) and / or

Traffic infrastructure features and / or other features. In one embodiment, the high accuracy map represents the updated first map. In another embodiment, the high accuracy map is recreated starting from on the first map.

A highly accurate position means a position which is so accurate within a given coordinate system, for example GNSS coordinates, that this position does not exceed a maximum allowable blur. In this case, the maximum blur, for example, on the environment - or the number and / or design of the environmental characteristics - depend. Furthermore, the maximum blur may for example depend on whether the automated vehicle is partially, fully or fully automated operated. Basically, the maximum

Blurring so low that in particular a safe operation of the automated Vehicle is guaranteed. For a fully automated operation of the automated vehicle, the maximum blur, for example, in the order of about 10 centimeters. There are various applications, in particular the operation - navigation, localization, moving by means of lateral and / or longitudinal control, etc. - one

automated vehicle that relies on a high accuracy map. The mobile device according to the invention advantageously contributes to this by simply, quickly and up-to-the-minute recording an environment with high precision in the form of a highly accurate map to a server.

In this case, the objects correspond, for example, to the environmental features that are encompassed by the first and / or the highly accurate map. This shows the advantage that in particular the current state of the environment is detected by means of the environment sensor, for example, objects in the environment, which are not covered by the first map, linked to a high-precision position (or determines their highly accurate position) and then be integrated into the first card, which is then available as a highly accurate map.

Preferably, the at least one object is designed as a traffic route, wherein the environment sensor is adapted to detect as length and / or size ratios a number of lanes of the traffic route and / or a width of the respective lane and / or a course of the respective lane. The current state of a traffic route, which is advantageously detected by means of the mobile device, is in particular for a secure and reliable operation of an automated system

Vehicle highly relevant. Just construction sites lead here temporarily or permanently to large changes (for construction sites, for example, the left lane of a multi-lane traffic route per direction of travel can be relocated to the opposite lane, etc.). Preferably, the mobile device is designed to be mobile.

By this is meant that the mobile device is designed, for example, such that it can be moved by a person (for example by means of wheels) without being carried.

This shows the advantage that the mobile device can be moved comfortably.

Preferably, the high accuracy card includes a timestamp representing the validity of the high accuracy card.

For example, a time stamp is a date on which the highly accurate map is created. Furthermore, the timestamp, for example, additionally or alternatively, a validity, for example, a duration in hours and / or days and / or weeks, etc., and / or another date and / or time, which represents a expiration of validity.

This shows the advantage that the high-precision card, in particular in the case of only a temporary change in the environment, without the environment having to be detected again, the highly accurate card, for example, replaced by the first card (on the server). By this is meant, for example, that depending on the time stamp, the first card is again provided instead of the high-precision card.
