Method for acquiring and providing a database which relates to a predetermined surrounding area and contains environmental data
First Claim
1. A method for acquiring and providing a database which relates to a predetermined surrounding area and contains environmental data relating to at least dynamic objects in the predetermined surrounding area, comprising:
- acquiring the environmental data from sensors of at least one motor vehicle;
providing access to the database by a first motor vehicle, acting as a server in the predetermined surrounding area, the first motor vehicle providing a central data collecting point and communicating with other motor vehicles, includingresponding to a request message received from a second motor vehicle by transferring at least a portion of the environmental data in the database to the second motor vehicle,transmitting an interrogation message and in response receiving transmission of the environmental data relating to at least the dynamic objects to and from the other motor vehicles,updating the database based on the environmental data relating to at least the dynamic objects obtained by the sensors of the first motor vehicle and the environmental data received by the transmission from the other motor vehicles, andtransferring, when a transfer criterion is satisfied, the database from the first motor vehicle acting as the server to a third motor vehicle which assumes responsibilities of the server.

Abstract
Data relating to at least the dynamic objects of the surrounding area is ascertained by sensors of at least one motor vehicle. The data is stored in a database provided by a motor vehicle, acting as a server for the surrounding area, which communicates with other motor vehicles. When a request message is received, the motor vehicle acting as a server transmits at least one part of environmental data in the database to the requesting motor vehicle and/or transmits a request message for transmitting environmental data, relating to the requested data about at least one object, to other motor vehicles to update the database and/or captures environmental data relating to the at least one object by other sensors. The database is updated to include the transmitted or captured environmental data.

11. A method for acquiring and providing a database which relates to a predetermined surrounding area and contains environmental data relating to at least dynamic objects in the predetermined surrounding area, comprising:
-
acquiring the environmental data from sensors of at least one motor vehicle; recording static objects which have a traffic-relevant changing state in the database; and providing access to the database by a first motor vehicle, acting as a server in the predetermined surrounding area, the first motor vehicle providing a central data collecting point and communicating with other motor vehicles, including responding to a request message received from a second motor vehicle by transferring at least a portion of the environmental data in the database to the second motor vehicle, transmitting an interrogation message and in response receiving transmission of the environmental data relating to at least the dynamic objects to and from the other motor vehicles, and updating the database based on the environmental data relating to at least the dynamic objects obtained by the sensors of the first motor vehicle and the environmental data received by the transmission from the other motor vehicles. - View Dependent Claims (12, 13, 14)

15. A method for acquiring and providing a database which relates to a predetermined surrounding area and contains environmental data relating to at least dynamic objects in the predetermined surrounding area, comprising:
-
acquiring the environmental data from sensors of at least one motor vehicle; providing access to the database by a first motor vehicle, acting as a server in the predetermined surrounding area, the first motor vehicle providing a central data collecting point and communicating with other motor vehicles, including receiving a request message from a second motor vehicle for at least a portion of the environmental data in the database, converting the environmental data in the database, taking into account a relative position information item contained in the request message, to a coordinate system of the second motor vehicle, before at least the portion of the environmental data in the database is transferred to the second motor vehicle, transferring at least the portion of the environmental data in the database to the second motor vehicle, transmitting an interrogation message and in response receiving transmission of the environmental data relating to at least the dynamic objects to and from the other motor vehicles, and updating the database based on the environmental data relating to at least the dynamic objects obtained by the sensors of the first motor vehicle and the environmental data received by the transmission from the other motor vehicles.
