Abstract: A method controls an operation of a motor vehicle equipped with a hybrid drive unit having a combustion engine and at least one electric machine that can be selectively operated as a motor or as a generator. The electric machine, when in generator mode, charges an energy store and/or supplies power to a vehicle electrical system of the motor vehicle. In generator mode, the electric machine is operated in alternating intervals, while maintaining predefined boundary conditions. In a first interval, the electric machine is operated with a first high electrical power output that is higher than an actual power consumption of the vehicle electrical system of the motor vehicle. The electric machine is switched off in a second interval. This largely prevents the electric machine from approaching operating points under light load which have a low efficiency and achieves a fuel advantage in comparison to a continuous operating mode.

Abstract: A method is for controlling an overrun condition in a hybrid vehicle having a combustion engine and additionally at least one electric motor as well as an overrun fuel cutoff, which interrupts a fuel supply to the combustion engine when the vehicle is in an overrun condition and restores the fuel supply when the combustion engine reaches or falls below a restoring speed. At least in a combustion engine at operating temperature, the fuel supply is restored at a restoring speed of at most 200 min?1, e.g., at most 100 min?1 above an idling speed of the combustion engine. The restoring speed may be in the range of the idling speed or only slightly above the latter. The restoring speed is thus clearly lowered as compared to the usual restoring speeds and extends the overrun fuel cutoff phases and thus reduces fuel consumption.
