    Development of a Vehicle Simulator for the Evaluation of a Novel Organic Control Unit Concept
    (INFORMATIK 2020, 2021) Brinkschulte, Melanie
    New challenges in the field of automotive systems (e.g. autonomous driving) require innovative and highly robust vehicle architectures. These are intended to increase the reliability and fault tolerance of the system and therefore realize the transition from Fail-Save to Fail-Operational behavior. Organic computing is a possible approach to achieve these goals. Based on an artificial hormone system and an artificial DNA, a novel organic control unit concept exists. In this paper we introduce an evaluation tool for this novel concept. Therefore, a simulator physically models the longitudinal and lateral dynamics of a vehicle. For an easy handling, visualization and reproducibility of experiments, an user interface and a scripting language are designed. In extensive evaluation runs the usability of the vehicle simulator is tested. Hereby, real vehicle data is used.

    Locating an Acoustic Source Using Low-Cost Hardware
    (INFORMATIK 2017, 2017) Brinkschulte, Melanie
    The availability of cheap but powerful sensors and signal processing hardware allows the solution of problems, which previously could only be solved at high costs and efforts. In this paper we describe an approach to locate an acoustic sound source by three low cost microphones and operational amplifiers in combination with a simple microcontroller using its embedded analog/digital converters. There are several applications, e.g. the detection of the direction and distance of a police car by the sound of its siren or the location of a speaking person by an assistance robot in a household. The complete real-time analog/digital signal processing chain using cheap hardware is in the focus of this approach. By deriving an approximate solution for the location equations, the approach becomes suitable for low-cost microcontrollers.
