Electrodynamic drive train

Abstract

A method for starting an internal combustion engine (4) in a vehicle equipped with an electrodynamic drive system (2), which is comprised of an electric motor (24) and a planetary transmission (14) between the internal combustion engine (4) and a manual transmission (6) with an input shaft (28), provides that first the electric motor (24) is accelerated to a speed that is fundamentally sufficient to start the internal combustion engine (4); this is followed by a controlled closing of a brake (32) designed to halt the rotation of the input shaft (28) of the manual transmission (6) against a stationary housing component (34), whereby a level of torque that represents the sum of electromotive torque and rotational torque of the rotating components acts upon the internal combustion engine (4).
