Abstract
Combustion gas of an internal combustion engine passes through an exhaust system to an outlet opening. A detection device generates a state signal that describes an engine noise of the internal combustion engine. A control apparatus actuates at least one loudspeaker to produce a sound at the outlet opening based on the state signal to compensate for the engine noise or produce another engine noise, independently of the state signal based on predetermined audio data and thereby to use the at least one loudspeaker to audibly output an advisory signal described by the audio data.

1-10. (canceled)
A motor vehicle, comprising:
- doors;
- a locking system for the doors;
- an internal combustion engine producing a combustion gas during operation;
- an exhaust system having at least one pipe taking away the combustion gas, during operation of the internal combustion engine, to at least one outlet opening of the exhaust system;
- a sensing device generating a state signal, during operation of the internal combustion engine, that describes at least one of a current engine noise and a current operating parameter characterizing operation;
- a detection device configured to detect a predetermined output situation, including at least one change of state of the locking system, and to generate a trigger signal in response to the predetermined output situation;
- at least one loudspeaker configured to emit a sound into a respective pipe of the exhaust system toward the at least one outlet opening;
- and
- a control apparatus configured to actuate the at least one loudspeaker to produce the sound based on the state signal to at least partially compensate for the current engine noise and/or to at least partially replace the current engine noise with a predetermined other engine noise, and, independently of the state signal, based on predetermined stored audio data, to audibly output an advice signal described by the audio data in response to the trigger signal that is independent of the state signal and generated in the predetermined output situation with a predetermined time delay.
