Because of the increase of world wide motorization, legislation aims at minimizing exhaust emissions of vehicles. One possibility to minimize these is to use special hybrid configurations. The authors have designed a hybrid testbed for use in parallel as well as serial hybrid configurations. The parallel configurations can be split into three major classes: pure starter generator functionality; mild hybrid; full hybrid. The aim was to use automotive components as far as necessary for a sufficient representation of reality. Automotive components widely use a CAN bus data link architecture but sensors often do not provide CAN interfacing. For easy integration of all components into one modular control system the authors decided to generally use the CAN bus. For the sensors converter circuits are used to first preprocess and second convert the sensor data to the CAN format. All data is collected and logged via 'xPC Target' from 'The MathWorks'. For drivetrain analysis and modeling as well as determination of fuel consumption in various drivetrain configurations the authors have developed a Matlab/Simulink based simulation tool called Fahrsim/Versim. Using xPC Target as a platform for both the simulation tool and the testbed automation, an easy data exchange between the simulation tool and the hybrid testbed is possible and simplifies verification of the testbed results.
