In 1993 six chairs of the Technical University Munich started a special scientific project with the aim to realize and investigate a parallel hybrid car concept, called the Autark Hybrid. In a first step drive line configuration was chosen and concept of drive line was worked out. Based on this concept simulations were made in order to estimate the potential of the Autark Hybrid drive line to reduce fuel consumption in comparison to usual drive lines with combustion engine and manual gearbox. By means of simulations optimal size of battery and electric engine for the chosen prototype car (a typical middleclass passenger car) where determined. The results of the simulations furthermore gave the basis for the development and optimization of the drive line components. In the meantime drive line is installed in a prototype vehicle and on a test rig. While test vehicle is needed to get real driving experience and prove function of drive line, test rig plays a key role in implementation, testing and detailed investigation of the drive line. The following paper describes the status quo of the work at the drive line test rig, showing actual measurement plots of an acceleration process and a FTP 72 cycle. For a better understanding a description of drive line, the concept of the Autark Hybrid and the test rig setup is given first.
