Abstract

A computer-implemented method for implementing a V2X application on target hardware having a radio adapter, wherein the V2X application is modeled in the form of a block diagram by means of a graphical modeling environment and the block diagram is compiled into a V2X program that can be executed on the target hardware and the V2X program is transferred to the target hardware and executed there. The method for implementing a V2X application is realized in an especially simple and advantageous manner in that a V2X communication block that has at least one radio adapter interface, by means of which data are exchanged between the radio adapter and the V2X communication block, is used to create the block diagram.
