The second generation of the modular P2 hybrid module represents the integration of a highly compact unit into a substantially unmodified classical design of drive train. The complete system comprises a damper, a decoupler integrated in the rotor with an actuator unit and an electric machine. The increase achieved in performance density forms the basis for integration with an optimum design envelope in existing transmissions and also opens up potential for realising a further increase in the extent of hybridisation. The module is this suitable for hybrids of the mild, full and plug-in variety, both in longitudinal as well as transverse mounting. For many years, active damping of vibrations by means of the electric machine has been discussed as an additional benefit of the module. Current results in this respect are presented. In addition to the second generation hybrid module, further development work is proceeding in which various approaches are required to address special requirements. The focus here is on development of entry hybridisation on the basis of 48 V systems, especially in conjunction with manual transmissions. The requirements specified at vehicle level have given rise to both coaxial and axially parallel solutions, which are then developed and presented individually.
