Definitions

  • the present application relates to an audio device for a vehicle and a group of model-type vehicles including the audio device.
  • Audio devices in vehicles are generally used to process and output audio signals and can serve various functions.
  • Such audio devices typically include mechanical and electromechanical components, for example controls that can be actuated by the driver or other occupants of the vehicle, audio signal sources such as music players, radio receivers or navigation systems, input units such as microphones and output units such as speakers.
  • audio signal sources such as music players, radio receivers or navigation systems
  • input units such as microphones
  • output units such as speakers.
  • An audio device may include, for example, a vehicle radio and/or an infotainment system and a variety of speakers.
  • emergency call systems for vehicles are increasingly being developed, e.g. a so-called "eCall system”.
  • An eCall system short for emergency call, is an automatic emergency call system for vehicles planned by the European Union, which will have to be installed in all new vehicle models and light commercial vehicles in the future.
  • Appropriate devices are installed in a vehicle for an eCall system, which can automatically report a traffic accident involving an equipped vehicle to the uniform European emergency number 112 and are thus intended to help to reduce the number of road deaths and the severity of injuries in the vehicle through the more quickly initiated rescue measures to reduce road traffic.
  • audio messages from a driver or other vehicle occupants are recorded, for example using a microphone, and sent to an emergency call center. Audio messages received from the emergency call center are output via one or more loudspeakers of the eCall system installed in the vehicle. In this way, a voice connection to the emergency call center can be established.
  • components for wireless communication between the driver or other occupants of the vehicle and an emergency call center must be available.
  • Various methods and devices are known for implementing such communication between a vehicle and other external communication devices, e.g. the emergency call center. Some of them go under the term "telematics".
  • the DE 10 2014 100 084 A1 discloses a method and system for establishing short-range wireless communication between a portable communication device and a vehicle telematics unit.
  • the telematics unit can then establish a connection to an emergency call center, for example.
  • such a telematics unit is attached to a window of the vehicle, for example, and has various modules, such as a GPS module for satellite positioning or a mobile radio module for Europe-wide data transmission.
  • the vehicle's position data is sent to a server via a mobile phone connection, for example, and evaluated there.
  • Portable communication devices can be, for example, smartphones and other mobile devices.
  • the disclosed method and system provides wireless configuration of a telematics service provider equipped vehicle by cellular service providers and telematics service providers.
  • FIG. 1 Such a prior art implementation is in FIG. 1 shown.
  • An audio device is in FIG. 1 represented schematically by an audio amplifier 104 .
  • Audio signals output from the audio amplifier 104 are output from various speakers.
  • the number of loudspeakers depends, for example, on an equipment variant of the vehicle.
  • a so-called center speaker 105 which can be installed in the middle of the vehicle's dashboard, is shown as an example.
  • the audio amplifier 104 can amplify audio signals from various audio signal sources, eg from an infotainment device. This provides a range of media in which a user of a vehicle can be both informed and entertained in a targeted manner.
  • Such an infotainment device can include, for example, a car radio, a navigation device, a vehicle information system, a CD or DVD player and the like.
  • FIG. 1 implements an emergency call system, in the example shown by means of an OCU ("Online Connectivity Unit") 102.
  • OCU Online Connectivity Unit
  • the OCU 102 can generally enable a connection between a vehicle and a so-called “back end”.
  • the back end can be, for example, a service provider running on a server that enables communication with the vehicle via a wireless Internet connection. Networking of different vehicles via the back end is also possible.
  • the communication can take place via a transmission and reception unit 101 which is coupled to the OCU 102 .
  • the OCU 102 can, for example, automatically establish a connection to an emergency call center via a mobile phone network as described above and provide a voice connection to the emergency call center via a microphone 101 and a loudspeaker 105 .
  • the speaker 105 must be installed in a place where a risk of damage in an accident is low. Since many other components are already installed in a vehicle, it is often not easy to find a suitable place for to find speaker 105.
  • the loudspeaker 105 is sometimes installed in central positions, for example in ashtrays or air conditioning units, which is sometimes complicated. To install the speaker in the ashtray, for example, its cover can be removed. Instead of the lid in the ashtray, a corresponding loudspeaker is integrated at the top.
  • the group of vehicles of a model type according to the invention then comprises at least one vehicle with a central loudspeaker and an audio device, and at least one further vehicle in which a loudspeaker is provided at the position of the central loudspeaker of the at least one vehicle only for the output of emergency calls.
  • Both the at least one vehicle and the at least one other vehicle have a control device which can be used for the at least one vehicle and for the at least one other vehicle, in that the control device always issues emergency call messages at a specific output which is connected to the position is.
  • the central loudspeaker is preferably a center loudspeaker of a loudspeaker system which also includes further loudspeakers, i.e. the central loudspeaker is preferably installed in the middle of the dashboard of a vehicle. Due to the central arrangement in the vehicle, the audio signal emitted by the central loudspeaker can be heard equally by people sitting to the left and to the right of the central loudspeaker. Alternatively, the central loudspeaker can also be installed in the interior mirror of a vehicle.
  • the central position of the central loudspeaker in the vehicle reduces the risk of it being destroyed in a traffic accident, in contrast to loudspeakers that are installed in the vehicle doors, for example.
  • loudspeakers can, for example, be destroyed by the impact of a side-on collision of the vehicle and no longer be functional.
  • the audio device for a vehicle includes one (ie at least one) at a predetermined minimum distance from the sides, front and rear of the vehicle to be arranged, central speaker and a control device.
  • the specified minimum distance can be, for example, at least 20 cm or at least 50 cm.
  • the center speaker is located on or near a center plane of the vehicle between the left and right sides.
  • the use of the central loudspeaker both for outputting emergency calls in the second operating mode and for outputting audio signals from the audio signal sources in the first operating mode, minimizes the effort involved in installing and implementing the audio device according to the invention.
  • No additional loudspeakers and brackets or additional installation space in the vehicle are required.
  • a loudspeaker provided anyway for the output of the audio signals can also be used for the output of the emergency call messages.
  • the line effort is lower.
  • a short production time is required for the production of the audio device.
  • emergency call messages are therefore output at the same loudspeaker position in all vehicles. This simplifies the wiring, for example.
  • a control device for example the OCU mentioned above, can be set up in such a way that it can be used for both configurations (central loudspeaker or special emergency call loudspeaker), for example by always issuing emergency call messages at a specific output, which is then wired to the corresponding loudspeaker position. In this way, vehicles with different equipment can be realized with comparatively little effort.
  • some vehicles that have a central loudspeaker are used to output emergency calls, as explained in detail above.
  • a special emergency call speaker is installed in the position of the central speaker.
  • control device of the at least one vehicle is set up to output an audio signal from an audio signal source to the central loudspeaker in a first operating state and to interrupt the supply of the audio signal to the central loudspeaker in a second operating state.
  • Emergency calls received from an emergency call center are sent to the central forwarded to speakers.
  • the control device of the at least one vehicle is set up to switch to the second operating state when an emergency call signal is sent from the vehicle to the emergency call center.
  • control device In a first operating state, the control device outputs an audio signal from an audio signal source to the central loudspeaker and, in a second operating state, interrupts the supply of the audio signal to the central loudspeaker.
  • control device In the second operating state, the control device also forwards emergency call messages received from an emergency call center to the central loudspeaker and can switch to the second operating state if an emergency call signal is sent from the vehicle to the emergency call center.
  • control device can also be supplied with power from its own battery and therefore remain active after a traffic accident and enable the emergency call messages to be forwarded to the central loudspeaker, even if the central power supply of the vehicle should be defective after a traffic accident.
  • audio signals from an audio signal source which can be a vehicle radio, an infotainment system or a hands-free device, for example, are output to the central loudspeaker in the vehicle.
  • the second operating state is assumed when an emergency call signal has been sent by the vehicle, for example after the vehicle has been involved in a traffic accident.
  • an emergency call signal can be generated, for example, by an eCall system as mentioned above.
  • the central loudspeaker In the second operating state, the central loudspeaker then assumes the function of outputting incoming emergency call messages from an emergency call center. The audio signals mentioned above are then no longer output via the central loudspeaker in this second operating state.
  • Emergency call messages received from the emergency call center are thus treated with priority over other audio signals and are automatically output via the central loudspeaker in the vehicle, so that they can be heard to the same extent by the occupants of the vehicle.
  • Emergency messages are generally understood to be messages, in particular voice messages, which the emergency call center sends to the vehicle. This automatic prioritization of emergency calls is particularly advantageous when, after a traffic accident, for example, the driver of the vehicle is no longer able to manually set functions in the vehicle so that emergency calls can be received by the emergency call center.
  • the emergency call signal triggers the switch to the second operating mode.
  • a central loudspeaker is used to output emergency calls.
  • the control device can have means for wireless communication with the emergency call center so that the control device can send the emergency call signal to the emergency call center. This can take place, for example, when an accident situation is detected via sensors in the vehicle. These emergency call signals are triggered, for example, via crash sensors, such as airbag sensors, which register an accident when the airbag has been deployed. Manual triggering, for example with a button, is possible on request.
  • the audio device may include a microphone.
  • the control device can forward a signal generated by the microphone to an emergency call center.
  • the microphone enables the users of the vehicle to communicate with the emergency call center.
  • the people in the vehicle then do not have to activate a microphone manually; this is done automatically using the audio device according to the invention.
  • an emergency signal can thus automatically be sent to an emergency call center, eg to a Processing device of the emergency call center are sent, for example, an implemented in the control device eCall system.
  • This eCall system automatically sends, for example, information about the location of the vehicle and any damage reports to the external processing device.
  • the emergency call center automatically receives an exact location report from the vehicle and can communicate with the users of the vehicle via the central loudspeaker which is integrated in the audio device according to the invention.
  • the emergency call center can thus receive further information about the severity of the traffic accident.
  • the audio device may include the audio signal source.
  • the audio signal source can include an amplifier and/or an infotainment system.
  • the central speaker can be used for a variety of different audio signal sources.
  • control device can send the emergency call message received from the emergency call center to an emergency call loudspeaker if no central loudspeaker intended for outputting audio signals from audio signal sources is installed in the vehicle.
  • Vehicles are often offered with different equipment variants, in particular with different speaker configurations.
  • a simple loudspeaker system in which no central loudspeaker is installed in the vehicle but, for example, a side loudspeaker, a simple emergency call loudspeaker can be installed.
  • This emergency loudspeaker can advantageously be installed at the same position in the vehicle.
  • the control device can be prepared for both alternatives (central loudspeaker and emergency loudspeaker), so that one control device can be used for different equipment variants.
  • Audio signals which are received via an amplifier of an audio system integrated in the vehicle, can be output via the central loudspeaker to the same extent and in the same quality both for the driver of the vehicle and for other users of the vehicle.
  • the amplifier can thus be integrated into an audio system, for example, and used as an audio amplifier.
  • the audio signals emanating therefrom are automatically sent to the central loudspeaker via the control device.
  • Audio signals from an infotainment device can also be forwarded via the control device to the central loudspeaker and can be prioritized accordingly, at least depending on which audio signal is required at which point in time.
  • a corresponding method according to the invention for controlling an audio device in a vehicle can include outputting an audio signal from an audio signal source to a central loudspeaker in a first operating state.
  • the method may further include changing from the first operating state to a second operating state when an emergency call signal is sent from the vehicle to an emergency call center.
  • the method can include interrupting the audio signal being fed to the central loudspeaker in a second operating state, and forwarding emergency call messages received from the emergency call center to the central loudspeaker in the second operating state.
  • the inventive method for controlling an audio device has the same advantages as the audio device discussed above.
  • the method can further include forwarding a signal generated by a microphone to an emergency call center in the second operating state.
  • the person in the vehicle does not have to manually activate a microphone in order to communicate with the emergency call center. This can be done automatically using the method according to the invention.
  • the method can further include outputting an emergency call message received from the emergency call center via an emergency call loudspeaker if no central loudspeaker is installed in the vehicle. Similar to the audio device, an adaptation to different equipment of a vehicle can take place here.
  • a vehicle may include an audio device and a center speaker.
  • the specified distance from the central loudspeaker ie the minimum distance from the sides, the front and the rear of the vehicle mentioned at the outset, can be at least 20 cm or also at least 50 cm.
  • the installation of a loudspeaker that is only provided for the output of emergency messages offers a more cost-effective alternative to an audio device with a central loudspeaker for audio signals in vehicles with simple equipment.
  • the same installation position of the emergency call loudspeaker and the central loudspeaker in all vehicles means that, apart from the loudspeakers, essentially the same configuration, e.g. wiring, can otherwise be used, which facilitates series production.
  • the audio device according to the invention can thus be installed in a standardized manner, that is to say a simplified installation on the assembly line, without having to provide solutions specially adapted for vehicles.

  • the central loudspeaker 202 is installed at a predetermined minimum distance from the sides, the front and the rear of the vehicle.
  • the predetermined minimum distance can, for example, be greater than or equal to 20 cm, preferably greater than or equal to 50 cm. Such a minimum distance reduces the risk of damage to the speaker in the event of an accident. More than one such central speaker may also be provided.
  • the audio signals output by means of the central loudspeaker 202 are heard equally well by all people in the vehicle due to the central installation position in the vehicle.
