A computer-implemented method for implementing a V2X application on target hardware having a radio adapter is provided. The V2X application is modeled in the form of a block diagram, wherein received telematics data of surrounding objects are recorded in an LDM object list. Detected telematics data of surrounding objects are recorded in a sensor object list, and, by comparing the LDM object list with the sensor object list, a telematics data comparison block determines differential surrounding objects that are recorded only in the sensor object list. For at least one differential surrounding object, a proxy V2X message with the telematics data of this differential surrounding object is created, and the block diagram is translated into a program that can be executed on the target hardware. The program is transferred to the target hardware and executed there, and the proxy message is sent by the target hardware over the radio adapter.


A computer-implemented method for simulating a restbus control unit network that includes at least two restbus control units connected through a bus system. The restbus control unit network is connected to at least one additional control unit through the bus system. The communication relationships of the restbus control units are described, program code for simulating the restbus control units is generated based on the communication relationships. The restbus control unit network is simulated on a simulation computer via an executable version of the program code. Simplified and flexible simulation of the restbus control unit network is made possible in that a single, joint restbus control unit model is generated for the restbus control units as program code for simulating the restbus control units.


A method for automated configuration of a tester equipped for testing a control unit. A first and second model of technical systems being executed in the tester. The execution of the models taking place periodically with defined sampling rates. An FPGA executes the first and/or the second model and a CPU executes the first or the second model. A first individual sampling rate is allocated for the first model and a second individual sampling rate is allocated for the second model. The first model is assigned for execution on either the CPU or the FPGA and the second model is assigned for execution on either the CPU or the FPGA. The tester is automatically configured for execution of the first model with the first allocated sampling rate on the FPGA or the CPU and of the second model with the second allocated sampling rate on the FPGA or the CPU.
