Single Shaft Parallel Hybrid Drive System 970286

A joint venture of four German companies was build to develop and realize a hybrid car with a aluminium space frame. This paper summarizes the project from idea to prototype car. To find out the right drive system a comparison of alternatives was made. The result shows a clear advantage of the „single shaft parallel hybrid system with automated shift gearbox”. The electric motor is a brushless permanent magnet synchronous machine with an outer rotor construction and liquid cooling system. The automated shift gearbox has a hydraulic actuator. The entire system is controlled by micro controllers.
