While most of the existing systems focus on a limited range of driving situations and use input from a single sensor (e.g. radar-based emergency braking systems or camera-based lane keeping assistance) future active safety systems will use the input of several sensors and assist drivers in highly complex traffic scenarios, thus leading the way toward automated driving. This development puts a big challenge on the Human Machine Interface (HMI). The Daimler commercial vehicle development recently established an interactive real-time test setup, where SIMPACK vehicle models are combined with a PreScan sensor simulation and an integration of the assistance system as Hardware-in-the-Loop (HiL) or Software-in-the-Loop (SiL). This allows interactive testing of various ADAS and the corresponding HMI in a variety of traffic scenarios and with realistic vehicle behavior.
