METHOD AND DEVICE FOR THE SELECTIVE TRANSMISSION OF DATA
First Claim
1. A method for selectively transmitting data from a transmitter to a receiver in a non-railbound land vehicle, wherein the method at the receiver end comprises:
- selecting at least one geographical region,wherein a geographical region corresponds to a limited area on a map,transmitting a request to the transmitterto transmit data relating to the at least one selected geographical region,receiving a data transmission initiated by the transmitter in response to the request,characterized in that a size of the limited area which corresponds to a geographical region and for which data are transmitted is adjustable, is automatically varied on the basis of a speed of the land vehicle, and/or is variable along a planned route, wherein regions at the start and end of a route, at planned intermediate stops or at intersections along the route are larger than on sections of the route which are driven through without stopping.

Abstract
A method for selectively transmitting data from a transmitter to a receiver in a non-railbound land vehicle comprises, at the receiver end, selecting at least one geographical region. In this case, a geographical region corresponds to a limited area on a map. After the at least one region has been selected, a request is transmitted to the transmitter to transmit data relating to the at least one selected geographical region, and finally a data transmission initiated by the transmitter in response to the request is received. The data relating to the at least one selected geographical region contain, in particular, information relating to a traffic route infrastructure in the geographical region, which information is valid for a limited period or for a longer time.

9. A method for selectively transmitting data from a transmitter to a receiver in a non-railbound land vehicle, wherein the method at the transmitter end comprises:
-
receiving a request from the receiver to transmit data relating to at least one selected geographical region to the receiver, extracting data relating to the at least one geographical region from a database, initiating a data transmission to the receiver in response to the request.

10. A transmitter-end apparatus having at least one wireless interface, a computer and a database which are communicatively connected to one another by means of one or more bus systems, characterized in that the computer stores program instructions which, when executed by the computer, carry out a method for selectively transmitting data from a transmitter to a receiver in a non-railbound land vehicle, wherein the method at the transmitter end comprises:
-
receiving a request from the receiver to transmit data relating to at least one selected geographical region to the receiver, extracting data relating to the at least one geographical region from a database, initiating a data transmission to the receiver in response to the request.

11. A receiver-end apparatus having at least one wireless interface, a computer and a device for determining a current position on the earth'"'"'s surface which are communicatively connected to one another by means of one or more bus systems, characterized in that the device for determining a current position on the earth'"'"'s surface or the computer stores program instructions which, when executed by the device for determining a current position on the earth'"'"'s surface or the computer, carry out a method for selectively transmitting data from a transmitter to a receiver in a non-railbound land vehicle, wherein the method at the receiver end comprises:
-
selecting at least one geographical region, wherein a geographical region corresponds to a limited area on a map, transmitting a request to the transmitter to transmit data relating to the at least one selected geographical region, receiving a data transmission initiated by the transmitter in response to the request, characterized in that a size of the limited area which corresponds to a geographical region and for which data are transmitted is adjustable, is automatically varied on the basis of a speed of the land vehicle, and/or is variable along a planned route, wherein regions at the start and end of a route, at planned intermediate stops or at intersections along the route are larger than on sections of the route which are driven through without stopping.
