Method for operating a hybrid vehicle and hybrid vehicle with a multi-cylinder internal combustion engine coupled to an electric motor

A hybrid vehicle comprising:

• a multi-cylinder internal combustion engine coupled to an electric motor having at least one partial power, from an overall drive power provided to the vehicle, provided by the internal combustion engine and a second partial power provided by the electric motor,
• a device for activating and deactivating a cylinder operable, upon the request for deactivating a cylinder that can be switched off, to cause said cylinder to be filled with fresh gas and, upon request of activating said cylinder, to cause an injection of a predetermined amount of fuel and to cause the ignition of the mixture in the temporal next suction and/or compression phase of the cylinder by no later than the end of the compression phase, and
• a device for adjusting the momentum operable to cause a multiple injection in a homogenous split mode of operation at the activation of a cylinder that was switched off.

A method for operating a hybrid vehicle with a multi-cylinder internal combustion engine coupled to an electric motor comprising at least one inlet and at least one outlet valve per cylinder, a variable valve control, and a fuel injection device for directly injecting fuel into the cylinders, with the overall driving power provided to the vehicle being provided in a first partial power by the internal combustion engine and a second partial power by an electric motor, the method comprising the steps of:

• upon the request for deactivating a cylinder that can be switched off, filling said cylinder with fresh gas and,
• upon request, to activate the cylinder, injecting of fuel multiple times in a homogenous split mode of operation and igniting a mixture of said fuel and fresh gas in the temporally next suction or compression phase of the cylinder by no later than the end of the compression phase.
