Abstract
A method for starting an internal combustion engine ( ) in a vehicle equipped with an electrodynamic drive system ( ), which is comprised of an electric motor ( ) and a planetary transmission ( ) between the internal combustion engine ( ) and a manual transmission ( ) with an input shaft ( ), provides that first the electric motor ( ) is accelerated to a speed that is fundamentally sufficient to start the internal combustion engine ( ); this is followed by a controlled closing of a brake ( ) designed to halt the rotation of the input shaft ( ) of the manual transmission ( ) against a stationary housing component ( ), 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 ( ).
