- vehicle functions and driver assistance functions include a wide variety of signal, warning and warning tones that draw attention to certain situations or prompt the driver to take certain actions. These tones are usually played through the vehicle's audio system. Due to the high number of different tones and different functions, it is possible that the driver does not know exactly what situation he is being alerted to or what action he is being asked to do. It is not uncommon for the operator to make sure Drivers by also consulting the visual signals displayed, such as an ad on a display.
- the invention has for its object to provide an audio device for a vehicle and a method for operating an audio device for a vehicle, which at least partially overcome the disadvantages in the prior art.
- a first aspect of the invention relates to an audio device for a vehicle, the audio device having a loudspeaker system.
- the loudspeaker system has a plurality of loudspeakers which are spatially arranged in such a way that they enable a three-dimensional listening experience in a vehicle interior.
- the audio device has a control unit which is coupled to the loudspeaker system and is designed to control at least one loudspeaker of the loudspeaker system in order to generate a position-specific warning signal which is associated with a specific position is linked to play. In order to reproduce the position-specific warning signal, the control unit controls only that speaker or speakers of the speaker system that are closest to the specific position.
- a second aspect of the invention relates to a method for operating an audio device for a vehicle, which is equipped with a loudspeaker system which has a plurality of loudspeakers which are spatially arranged in such a way that they enable a three-dimensional listening experience in a vehicle interior.
- the method comprises the control of at least one of the several loudspeakers of the loudspeaker system in order to reproduce a position-specific warning signal which is linked to a specific position. Only the speaker or speakers of the several speakers that are closest to the specific position are controlled.
- a vehicle in the sense of the present document is to be understood to mean any type of vehicle with which people and / or goods can be moved.
- motor vehicles trucks, land vehicles, buses, driving cabins, cable car cabins, elevator cabins, rail vehicles, water vehicles (e.g. ships, boats, submarines, diving bells, hovercraft, hydrofoil boats), aircraft (airplanes, helicopters, ground effect vehicles, airships, balloons ).
- water vehicles e.g. ships, boats, submarines, diving bells, hovercraft, hydrofoil boats
- aircraft airplanes, helicopters, ground effect vehicles, airships, balloons ).
- the vehicle is preferably a motor vehicle.
- a motor vehicle in this sense is a land vehicle that is moved by machine power without being tied to railroad tracks.
- a motor vehicle in this sense comprises a motor vehicle, a motorcycle and a tractor.
- the coupling for example the coupling between the loudspeaker system and the control unit, means a communicative connection.
- the communicative connection can wireless (e.g. Bluetooth, WLAN, cellular) or wired (e.g. using a USB interface, data cable, etc.).
- the audio device has a loudspeaker system with several loudspeakers.
- the loudspeakers are spatially arranged so that they enable a three-dimensional listening experience in a vehicle interior.
- the vehicle interior in the sense of the present document comprises the passenger compartment of a vehicle, that is to say the space in which the vehicle occupants are located, the interior trim, seats, benches, dashboard, other fittings, operating elements and the trunk of a vehicle.
- a vehicle occupant in the sense of the present document is a living being, preferably a person, who is in a vehicle. It does not matter where the vehicle occupant is or what the occupant is doing.
- the term three-dimensional listening experience means a listening experience in the horizontal and vertical directions.
- audio signals are distributed to the individual speakers so that different soundscapes can be generated.
- a possible soundscape can, for example, cause a listener to feel enveloped by the tones (for example music, language, sound effects).
- the soundscape can be designed so that the listener can assign it to a specific object or a specific direction. This can be achieved, for example, by using audio methods that deliver object-based audio data to loudspeakers.
- the three-dimensional listening experience allows audio signals to be precise depending on a specific direction or position are reproduced. This increases the intuitive perception of audio signals from a certain direction or from a certain position. This means that a vehicle occupant in a vehicle interior can experience a three-dimensional listening experience through the specific arrangement of the loudspeakers and can differentiate whether the audio signals span a space around them or come from a specific direction or from a specific position.
- the control unit controls at least one loudspeaker of the loudspeaker system.
- the control unit causes at least one loudspeaker of the loudspeaker system to reproduce a position-specific warning signal.
- the control unit delivers object-based audio data to the corresponding loudspeaker of the loudspeaker system.
- the control unit is communicatively connected to the speaker system.
- position-specific warning signal means that the warning signal is linked to a specific position. In other words, only a specific loudspeaker or only specific loudspeakers of the loudspeaker system are activated, so that a vehicle occupant perceives the warning signal coming from a specific position. That That means that this warning signal is not reproduced via all loudspeakers of the loudspeaker system, but that individual loudspeakers are specifically selected and controlled for the reproduction of the position-specific warning signal. This gives the listener the impression that the warning signal is linked to a specific position. The listener can thus intuitively assign the warning signal to the specific position.
- warning signal is understood to mean an audible signal which indicates a potential or acute danger or an impending or action to be taken.
- the warning signal preferably relates to one or more specific vehicle functions and / or an operating state of one or more specific vehicle functions and / or one or more specific vehicle parts and / or a state of one or more vehicle parts.
- vehicle functions are: tire pressure measurement, seat occupancy, vehicle occupant seat belt application, obstacle detection, blind spot obstacle detection, side collision detection, front collision detection, rear collision detection, object detection, environment detection, etc.
- vehicle parts are: flap, window, loading flap, tailgate, Bonnet, trunk lid, cargo compartment lid, sunroof, folding roof, fuel filler flap, door, convertible top, vehicle seat belt, tires, vehicle seat, etc.
- a control unit in the sense of the present document is to be understood as a central or decentralized system which is intended to receive, process, output and, if necessary, store information, for example in the form of signals and / or data.
- the control unit can be a device in the vehicle, for example the on-board computer, the navigation device, the infotainment system, etc.
- the control unit or individual parts of the control unit can be an external device and / or a mobile terminal.
- a control unit in the sense of the present document has in particular at least one central processing unit (CPU, microcontroller, etc.) and, if appropriate, a memory device.
- control unit can have encoders and / or decoders which prepare received information for processing by the central processing unit and / or information to be output for output (ie for transmission), in particular via a data transmission system (for example BUS System).
- a data transmission system for example BUS System.
- the audio device for a vehicle described herein enables the vehicle occupants to intuitively perceive warning signals, to classify them and, if necessary, to take appropriate measures. As a result, the driver of the vehicle is not unnecessarily distracted from his task of driving the vehicle, for example.
- the position-specific warning signal is linked to a specific position in the vehicle interior.
- the warning signal therefore relates to a specific position in the vehicle interior.
- the warning signal gives a vehicle occupant the feeling that it starts from a specific position in the vehicle interior.
- the respective loudspeaker or the respective loudspeakers that are closest to the specific position in the vehicle interior are activated in order to reproduce the warning signal. If, for example, the warning signal "open door" is to be heard from the right rear vehicle door, the loudspeaker or the loudspeakers next to the rear right vehicle door are activated.
- the position-specific warning signal is generated by changing the sound settings of audio signals transmitted via the loudspeaker system at the loudspeaker or loudspeakers of the loudspeaker system that are closest to the specific position.
- the warning signal is generated by the sound settings emitted by Audio signals are only changed on a specific loudspeaker or on specific loudspeakers (namely the loudspeaker or loudspeakers that are closest to the specific position).
- Tone settings can include parameters for tone control, for example parameters of an equalizer.
- the sound settings can include, for example, the highs, the lows and / or the volume.
- the term “transmitted audio signals” is to be understood to mean continuously played audio signals, such as, for example, music, news, audio books, telephone calls, video conferences, etc.
- the audio signals are played through the speaker system, e.g. the radio is running and at some point the sound settings on a particular speaker or on certain speakers are changed. A vehicle occupant can perceive the changed sound settings
- a running music player can be adapted to play a position-specific warning signal in such a way that the sound of the music player only changes in a certain spatial direction, particularly in relation to the driver.
- Such a change could be implemented, for example, via dynamic frequency adjustments of the reproduction with respect to one direction.
- Sound settings Settings for bass and treble of the audio signals can be changed by raising or lowering the bass and / or raising or lowering the treble.
- a vehicle occupant therefore perceives the position-specific warning signal in that he perceives a change in the sound of the audio signals on a specific loudspeaker or on specific loudspeakers during the reproduction of audio signals. For example, an increase the depths on a rear right speaker are perceived as a position specific warning signal by that rear right speaker. If, in turn, while listening to music on all loudspeakers, the heights of the music reproduction are only audibly raised on a certain loudspeaker in the front right (i.e. in the front passenger seat), a vehicle occupant perceives this change in the front right and can assign this to a position-specific warning signal.
- a further warning signal for example a loud signal tone, can be reproduced via one or more loudspeakers. This further increases the perception of the warning signal.
- control unit is further configured to receive object data on an object detected in an environment of the vehicle and to vary the content of the position-specific warning signal as a function of the received object data.
- object data means data that describe the object. Examples of such object data are: size, length, width, depth, consistency, speed, acceleration, weight, etc.
- the object data for an object detected in an environment of the vehicle can be determined by a detection device arranged in the vehicle and / or on the vehicle and / or outside the vehicle.
- the detection device can comprise a sensor system.
- the sensor system comprises at least one of the following devices: ultrasound sensor, radar sensor (eg near-range radar sensor, far-range radar sensor), lidar sensor, thermal imaging camera system, video system and / or image sensor (eg camera).
- the data (ie the object data in the present case) of the sensor system can originate from one of the aforementioned devices or from a combination of several of the aforementioned devices (sensor data fusion).
- the detection device is coupled to the control unit for receiving the object data.
- the content of the position-specific warning signal is varied depending on the object data received.
- the term “content of the position-specific warning signal” means the melody, the sequence of tones, the tones and / or the length of the warning signal.
- a certain object or a certain object class can be concluded.
- the position-specific warning signal can include, for example, the ringing of a bicycle bell in order to warn of a cyclist approaching the vehicle.
- the position-specific warning signal can include a child's smile to indicate a child in the area surrounding the vehicle.
- the position-specific warning signal can, for example, include the noise of a train in order to draw attention to an approaching level crossing.
- a position-specific warning signal is a certain sound, for example a beep or a whistle, which draws attention to an open door or an opened tailgate.
- the type of warning tone ie the content of the warning signal
- the content of the position-specific warning signal therefore provides information about what should be warned about. Because the warning signal is reproduced in a position-specific manner, information about the position or the direction from which the warning is emitted is additionally transmitted. A vehicle occupant thus intuitively receives information about a warning.
- the control unit is designed to reproduce a course of a position-specific warning signal, the control unit for successively controlling at least two loudspeakers of the loudspeaker system to reproduce the course of the position-specific warning signal.
- the position-specific warning signal is first reproduced on a loudspeaker; the speaker is then switched to reproduce this position-specific warning signal in order to reproduce a course of the position-specific warning signal.
- the reproduction of the course of the position-specific warning signal is therefore essentially not played simultaneously on two or more loudspeakers, but in succession on two or more loudspeakers.
- the warning signal may be played back briefly on two or more speakers at the same time. In other words, playback on one loudspeaker can change to playback on another loudspeaker (“crossfade”).
- control unit is further configured to receive object data on an object detected in an environment of the vehicle and, depending on the received object data, the sound settings of the audio signals transmitted via the loudspeaker system on that or to change those loudspeakers of the loudspeaker system that are closest to the detected object. The control unit can then vary the content of the position-specific warning signal generated in this way.
- a position-specific warning signal is first generated on the loudspeaker that is closest to the cyclist by lowering the levels of the audio reproduction on this loudspeaker. If the driver does not respond to this warning signal, a bicycle bell can be sent as a warning signal via the loudspeaker, which is then closest to the cyclist at this point in time.
- the audio device comprises a selection unit that is designed to provide a specific selection of contents of a warning signal for the assignment of a specific content to a specific vehicle function and / or a specific vehicle part put.
- a certain content of a warning signal for example a fanfare tune
- the selection unit for a specific vehicle part for example a vehicle door. be assigned. If, for example, the warning signal for an open vehicle door is played, a fanfare melody sounds. This fanfare melody only sounds on the loudspeaker or on the loudspeakers that are closest to the respective open vehicle door.
- the specific selection of contents of a warning signal made available by the selection unit is freely configurable.
- the warning signal for an open vehicle door can be configured as a beep and the warning signal for a dog recognized in the vicinity of the vehicle can be configured as dog axes.
- the plurality of speakers include vehicle seat speakers. At least one vehicle seat loudspeaker is assigned to each vehicle seat.
- the position-specific warning signal is a seat belt reminder signal. To reproduce the seat belt reminder signal, the control unit controls only the one or those vehicle seat loudspeakers which are assigned to the vehicle seat for which the seat belt reminder signal is intended.
- At least one vehicle seat loudspeaker is assigned to each vehicle seat.
