In a method for operating a parallel motor vehicle hybrid drive, with an internal combustion engine which is connected to a drive shaft via a clutch and a manual transmission, and with a three-phase machine which is directly coupled with its rotor to a countershaft of the manual transmission and is connected to an electrical energy store via a three-phase converter, a time average of the driving torque required during a respective predeterminable travel time interval is determined by a hybrid drive control unit. The power outputs of the internal combustion engine and of the three-phase machine are controlled so that the internal combustion engine outputs driving torque corresponding to the time average determined, and the three-phase machine outputs the difference between the driving torque currently required and the driving torque delivered by the internal combustion engine.
