Abstract
The invention relates to a method for operating a hybrid vehicle, in particular a series-produced hybrid vehicle, comprising at least one electric motor and at least one internal combustion engine, wherein the internal combustion engine is operated in at least one first operating range (B, D) of the vehicle, in particular in a stationary manner, and is deactivated in at least one second operating range (A, C) of the vehicle. In order to enable a basic constant sound without sudden changes, a basic sound (SB) which corresponds to the operating sound (SC) of the internal combustion engine is generated during the second operating range (A, C).

- 14. A method for operating a hybrid vehicle, comprising at least one electric motor and at least one internal combustion engine, with the internal combustion engine being operated in at least one first operating range of the vehicle and being deactivated in at least one second operating range of the vehicle, wherein a basic sound is artificially generated during the second operating range, which basic sound corresponds to an operating sound of the internal combustion engine.
- 28. An apparatus for performing a method for operating a hybrid vehicle, comprising at least one electric motor and at least one internal combustion engine which can be operated in at least one first operating range of the vehicle and which can be deactivated in at least one second operating range of the vehicle, wherein the apparatus comprises a sound emission device, a synthetic sound generation device and a control device, with the control device having an input for at least one operating parameter of the internal combustion engine, and with the sound generation device being activatable and deactivatable by the control device depending on the operating parameter.
