1.2. Goal and Structure of this Work 1.2. Goal and Structure of this Work Thepresentwork focusesontheparametrizationprocessofADAS. Itproposesamethod for parametrizing an ADAS with the help of real-world test drives with non-professional drivers. The suggested method is validated by applying it to determine the controller parameters for an ACC controller. The hypothesis behind this research is that ACC systems parametrized by human behaviour will be better accepted, and this process will therefore provide a valuable tool for vehicle development. Chapter 2 provides an overview of the required components of an ACC system, which focuses on the environmental-recognition sensors and offers examples of different upper level controllers of the ACC that are mentioned in literature. Chapter 3 introduces the commonly used development process for ADAS. It shows the trade-off between shortening the development time for ADAS and delivering a system that satisfies the customer. Chapter 4 describes measurements obtained with a specially equipped vehicle. A very complicated measurement setup was used to synchronously measure the movement of two vehicles during the tests. In addition, a production Radio Detection and Ranging (RADAR) sensor delivers the data received by an ACC system in an ACC vehicle. Based on these measurements, chapter 5 describes the selection of the Object to Follow (OTF). To this end, algorithms from literature and a new algorithm are applied to the measured data, and the output is validated. Chapter 6 introduces a new non-linear ACC controller. The data measured for the OTF was used to parametrize this controller, and the identified parameters were verified via simulations. The output of the simulations indicates the high potential of the proposed method and the novel ACC controller. Chapter 7 summarizes the key findings by chapter and provides a final statement. 7
