    • The invention relates to a method and to a device for starting an internal combustion engine with a summed torque, extending in a wave form over a rotational angle of the crank shaft of said internal combustion engine, by means of an electric machine which is rotationally coupled to the crank shaft and rotational elasticity which is effective between the crank shaft and the electric machine. In order, in particular in the case of large summed torques, to permit the internal combustion engine to be started with an electric machine which has a low step-down ratio compared to the crank shaft or is optimized for small power levels, at the start of a starting process the crank shaft which is positioned between two wave peaks of the summed torque is rotated by means of the electric machine through a predefined rotational angle in the opposite direction to a direction of rotation of the crank shaft during the operation of the internal combustion engine with a smaller summed torque than a maximum summed torque, and the rotational elasticity is prestressed and subsequently accelerated by means of the electric machine with a reversal of the direction of rotation in order to overcome the maximum summed torque.
