The proposed method offers maximum consistency in the model-based development of driver assistance systems. Based on an identical model platform MIL, SIL, HIL and VIL tests can be performed - with test scenarios that have to be configured only once and can be reused in all domains. Furthermore, the possibility of test automation ensures high productivity. The TestManager of CarMaker manages all maneuver-based tests, runs them automatically and files the results in protocols. The driver model IPGDriver carries out the maneuver task list of the TestManager. In the case of the VIL tests, IGPDriver accesses the actuators of the real-world test vehicle in real time. This means that the test vehicle is not driven by a human driver but by a driver model. This makes it possible to either maintain consistent driver behavior or to specifically vary it in order to systematically investigate the influence of the driver (for instance, his braking behavior) on the functions of the assistance system. The tests and test results are exactly reproducible and the automation leads to a significant reduction of time and costs. Another advantage of VIL simulation is the possibility of testing the driver in conjunction with the future assistance system in a virtual, augmented environment. In just a few years from now, manufacturers will launch vehicles on the market that in certain driving scenarios use partial or fully automatic driving capabilities (e.g. the "autopilot" on freeways). Even more than today, the design of the interface between the driver and the vehicle will be crucial, as the consumer who buys an "autopilot" expects to use it in order to be able to do something else besides driving. But it must be assured that the driver can be brought back "in-the-loop" at any time. Therefore, the development of handover strategies, the communication between the driver and the vehicle as well as driver monitoring are special aspects in the evolution of today's driver assistance systems into partially or fully autonomous systems. The Vehicle-in-the-Loop simulation including the Augmented Reality method offers a safe, realistic and resource-saving testing procedure for the comprehensive investigation of the interaction between the driver and the autonomous vehicle.
