Part IV: ICT infrastructure for automated driving and future traffic management 12 Cooperative system integration

Kurzfassung

While cooperation offers a lot of benefits, the development of cooperative systems raises the complexity much. Now, not only the entity s behaviour needs to be developed separated of each other, but also the behaviour of the whole system. Key for such developments is of course a very precise definition of interfaces between the components and the entities, but the interdependency of the behaviour is the much more critical point. As it is not really simple to forecast the result of a given action of one entity to the others (imagine the effects of one sharp braking of a single car on highways which sometimes is the starting point of shockwaves in the system), testing of such systems is very important. Since testing of vehicle automation functions itself is still a topic under investigation (see e.g. H2020 Enable-S3 and the German national project Pegasus), it is clear that esp. system tests including several cars on an intersection needs new methods of testing. In MAVEN, the complete system had to be developed within roughly two years from getting the idea to having a real prototype on public roads, putting even more pressure on the development. This chapter is showing how the integration and testing was done within MAVEN, starting from simple simulation runs, doing hardware in the loop tests, preparing on test tracks with augmented reality and finally testing on the public road.
