Definitions

  • the invention relates to a method for operating an audio system in a motor vehicle having a data source, a control device and a plurality of sound sources distributed in an interior of the motor vehicle and an audio system.
  • an audio system in order, for example, to receive traffic messages and to reproduce them to a user of the motor vehicle.
  • an audio system includes a data source, eg. B. in the form of a radio receiver, a cassette, a CD and / or a DVD player or MP3 player.
  • the signal of the data source is optionally forwarded via an amplifier to a plurality of sound sources distributed in the interior of the motor vehicle in order to offer the user of the motor vehicle the best possible listening experience.
  • the entire control of the audio system via a control unit, which is integrated in the audio system, for example, used in a standard bay car radio, and controls, for example, according to the position of the volume control the sound sources.
  • the sound sources z. B. on the right and left side of the dashboard of the motor vehicle and / or left and right at one Hat rack can be arranged in the rear of a limousine.
  • a data source which supplies a stereo signal either the sound sources on the left or right side seen in the direction of travel are activated with a balance controller in order to generate a higher sound pressure on these pages.
  • the rear or front sound sources can be set louder or quieter with a fader.
  • sound sources are here u. a. To understand membrane or Kalottenlaut Sacher that produce sound waves of desired frequency and intensity in a conventional manner according to their control.
  • the sound sources can also be designed to deliver only certain frequency ranges, z. B. in the form of low, mid and tweeters.
  • the audio system is usually set by the user or driver of the motor vehicle so that he feels a subjectively pleasing for him listening experience.
  • the different sound sources are controlled differently with the balance control and the fader, for example.
  • the present invention seeks to provide a method for operating an audio system in a motor vehicle, with the always reproduced by the audio system information, eg. As the traffic news, can be clearly and clearly perceived. Furthermore, a corresponding audio system should be specified.
  • the core idea of the invention is that an audio system already present in the motor vehicle with a data source, a control unit and a plurality of sound sources distributed in the interior also receives a signal regarding the occupancy of the interior, in particular the number of persons located in the interior of the motor vehicle. is forwarded. Based on this signal, the audio system or its control unit can conclude whether the handlebar has taken place alone on the driver's seat or in addition other people or other objects are in the interior. If only the handlebar in the interior, the audio system can be adjusted so that the sound field known to the expert is generated at the place of the driver or at the place of his head in which, for example, traffic messages are clearly understandable.
  • the audio system can be controlled in such a way, ie the individual sound sources with different intensities each, that compensates for these effects and at least the driver is still provided with the best possible sound field.
  • the signal or the type of detection of the number of persons in the interior or of other objects can be configured as desired, but preferably as described below. It is in principle possible to manually enter the number of persons and their distribution and / or the presence of other objects to the control unit or the audio system, for. B. via a menu-guided entry via a display.
  • control unit of the audio system which may also be integrated in a central control unit for controlling all functions in the motor vehicle, hardware and / or software is designed such that the audio system to a different number of people and the presence of other objects can be adjusted in the interior of the motor vehicle.
  • sensors may communicate with the controller via a CAN bus for data exchange.
  • the occupancy with persons and / or objects in the interior of the motor vehicle is detected by sensors according to claim 2.
  • sensors can be done for example by means of sensors on the damping system or with tire pressure sensors via a detection of the current total weight of the motor vehicle, the difference between a curb weight and the current total weight evaluated and, for example, by a standard value for an adult person, about 80kg, divided and it is deduced from the number of persons from the control unit.
  • the payload can be determined from the thus changed acceleration and braking behavior of the motor vehicle.
  • objects and / or people that are present in the interior of the motor vehicle are taken into account by the audio system or the control unit by means of a signal from a microphone.
  • Such items eg. As a lightweight cardboard, which does not cause a response of a seat occupancy sensor lead z. B. due to their sound-absorbing material yet to a significant change in the sound in the interior. This can u. a. be monitored with one or more microphones distributed in the interior. As soon as such a change in the sound quality, even if the number of people in the interior should not have changed, is determined by the controller, the sound sources are driven accordingly to compensate for this again.
  • the audio system is designed such that a separate sound field is generated for each person.
  • the different sound sources in particular separated according to different frequency ranges, can each be controlled with different intensity.
  • the audio system can be operated with an occupancy of the interior only with the driver so that the left front sound sources are relatively quietly controlled and the right rear sound sources relatively loud, so as to produce a pleasant for the driver sound field in his head. Then climb z. B. in a sedan four people, so that the motor vehicle is fully occupied, both the number of people and their distribution can be detected and the sound sources are controlled such that five sound fields are generated at the positions of persons to each person as possible to provide an optimal listening experience.
  • sound sources are controlled, the only in the operation of the audio system for a single person, d. H. the handlebar, are passive.
  • an additional source of sound may be present to separately sonicate that seat in the event that a person has taken a seat on it.
  • a sound field synthesis allows each passenger to best hear his or her particular audio source from a plurality of available sources, for example one of several replayable radio programs, or to perceive no audio signals if he wishes to remain undisturbed.
  • FIG. 1 From the illustration in Figure 1, the schematic representation of an interior 1 of a motor vehicle in plan view can be seen.
  • four sound sources 2 a, 2 b, 2 c, 2 d are respectively arranged at the corners of the inner space 1.
  • the sound sources 2 are for example commercially available speakers of an audio system, wherein a sound source 2 and several speakers, z. B. a low, middle and tweeter may include.
  • sensors 3 which can be configured as desired by a person skilled in the art, which are shown here by way of example as sensors 3a, 3b for monitoring the interior. It can the sensors 3a, 3b may be formed, for example, by an optical detection system with which the number and distribution of the persons 4 or other objects in the interior 1 of the motor vehicle can be detected.
  • the sensors 3 preferably forward their signals via data bus architectures known in motor vehicle technology to a control unit of an audio system of the motor vehicle, the control unit, which can also be integrated in a central control unit for controlling all functions of the motor vehicle, depending on the signals of the sensors 3, the audio system or the sound sources 2 so controls that for each person 4 a best possible listening experience is brought about.
  • the sound source 2d is actuated at the right rear in the interior 1 with a greater volume than the other sound sources 2a, 2b, 2c, in particular the left front seated arm 4a the motor vehicle also to provide a sufficient and uniform volume distribution of all sound sources 2, since the distance between the person 4a and the sound source 2d is greater than, for example, the distance to the sound source 2a.
  • the sound sources 2 are controlled in such a way that for each of the three persons 4a, 4b, 4c a separate sound field with the best possible listening experience is generated.
