    摘要： The invention relates to a method for controlling an operation of a motor vehicle equipped with a hybrid drive unit (10), which comprises a combustion engine (12) and at least one electric machine (14) that can be selectively operated as a motor or as a generator. The electric machine (14), when in generator mode, charges an energy store (22) and/or supplies power to a vehicle electrical system (24) of the motor vehicle. The invention provides that in generator mode the electric machine (14) is operated in alternating intervals, while maintaining predefined boundary conditions, wherein: (a) in a first interval, the electric machine (14) is operated with a first high electrical power output that is higher than an actual power consumption of the vehicle electrical system (24) of the motor vehicle; and (b) is switched off in a second interval. This largely prevents the electric machine (14) from approaching operating points under light load which have a low efficiency and achieves a fuel advantage in comparison to a continuous operating mode.

It is provided that during a startup process of the internal combustion engine (10) fuel is injected by at least one of the following measures: (a) activation of the fuel injection into the at least one combustion chamber (54) only after a minimum fuel pressure is reached, and (b) monitoring a course of a run-up of the internal combustion engine (10) after fuel injection has begun and, if a deviation of the course from a desired course is detected, at least partial compensation of the deviation by a motor intervention of the at least one electric machine (26). The startup process can be performed so as to result in considerable fuel savings and low emissions.
