Abstract
A drive system for a vehicle has an internal combustion engine and a torsional vibration damping arrangement. The internal combustion engine is switchable between operating modes of different performance. The torsional vibration damping arrangement includes an input region, which can be driven in rotation, and an output region. A first torque transmission path is provided between the input region and output region, and a second torque transmission path is provided parallel thereto. A coupling arrangement superposes the torques transmitted via the torque transmission paths, and a phase shifter arrangement is provided in at least one torque transmission path for generating a phase shift of rotational irregularities transmitted via the one torque transmission path in relation to the rotational irregularities transmitted via the other torque transmission path.
