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.
