TRUDI: Testing Environment for Vehicular Applications Running with Devices in the Loop Vehicles will be equipped with shortrange wireless technologies with the aim to improve safety and traffic efficiency. Novel applications are thus being implemented for future cars and trucks, and one of the main issues is how to conduct tests and optimizations in an effective way, limiting the need to perform costly and time consuming experiments on the road. To cope with this issue, we have implemented a simulator with hardwareintheloop (HIL), called TRUDI, where the hardware and the implemented applications are tested in the laboratory by injecting virtual positions of the vehicles with the support of a traffic simulator. TRUDI acts as a maninthemiddle between the communication module and the application itself, making it possible to perform tests with the real devices and providing as an output a system ready for the road. Using TRUDI, it is possible to check the application with a few vehicles and real wireless devices or many vehicles using simulated communication components before moving to experiments on the road. As an example use case, an application for the intersection management is presented, where the driver is warned of the presence and speed of other vehicles approaching the same junction.

Interference Tests of ITSG5 VehicletoVehicle Communication Networks with Virtual Drive Tests Automotive communication systems have become a hot topic in the research field, especially with a focus towards connected vehicles. The potential of connected and automated driving promises an enormous increase of road safety and traffic efficiency. With this purpose, dedicated short range communication standards (e.g. ITSG5) have been developed. These standards share spectral resources among all communication partners, which necessitates an evaluation of inband interference. As one potentially powerful evaluation approach, the road and radio environment can be emulated instead of being accessed through fieldoperational tests, with major advantages like repeatability and convenience aspects. This paper describes a testing framework that employs a virtualdrive test approach for the evaluation of the performance of ITSG5 equipment. According to the concept of virtualdrive testing, the road and radio environments have been emulated with regards to a realworld drive track. Packet loss measurements are presented for the evaluation of interference effects present in the communication. The results indicate that the virtualdrive test approach is suitable for testing automotive communication systems.
