Zusammenfassung:A method and a device for starting an internal combustion engine of a motor vehicle, the internal combustion engine exerting a drive torque on a crankshaft in one direction of the internal combustion engine, a starting motor exerting a starting torque on the crankshaft during a starting process to achieve a minimum rotational speed of the internal combustion engine, and a control unit regulating the starting torque. The control unit regulates the starting torque in a time-dependent manner between a positive maximum starting torque and a negative minimum starting torque during the starting process, a positive starting torque acting on the crankshaft in one direction and a negative starting torque in the opposite direction.
