Abstract

The invention relates to a drive assembly of a motor vehicle, having a internal combustion engine and an electrical machine coupled or capable of being coupled to a crankshaft of the engine, wherein the electrical machine can be switched to motor and generator modes, and having an electronic control unit for controlling direct injection and ignition of the engine. It is provided that at the start of the engine (12) the crankshaft (16) can be put in a predeterminable starting position via the electrical machine (22) switched for motor operation, and upon attaining the starting position of the crankshaft (16), the ignition of the fuel injected into a starting cylinder (14) is effected, and via the electrical machine (22), a torque can be exerted on the crankshaft (16) during the entire starting operation.
