(WO9708008-A1)      The hybrid drive system comprises an internal combustion (IC) engine, and at least one electric machine for providing a drive slip or traction control arrangement in which the electric machine (4) is designed to reduce drive slip, in particular by braking action and/or by electromagnetic coupling slip action in the drive train. The electric machine functions specifically as an eddy-current brake for producing a reduction in drive slip, and more specifically as a generator brake, in which the electrical energy produced by recuperative (dynamic) braking is stored for re-utilisation or is converted into heat. The automatically actuated coupling is arranged between the drive unit and the electrical machine, and is fully or partially opened when the drive torque is reduced, or more specifically the electric machine is itself designed as an electromagnetic coupling.    Energy stored in the flywheel during braking, the flywheel being connected, via the electrical machine into which it feeds back the stored energy, to the drive system, can be re-used to complement the use of the electrical machine as part of a hybrid-drive arrangement where the electrical machine can provide or support an acceleration of a drive shaft in order to accelerate the vehicle.    USE/ADVANTAGE -   Motor vehicle hybrid-drive system with traction control Improved drive slip control arrangement. Compact and simplified design.
