Definitions

  • the invention relates to an emergency call method for vehicle users and a vehicle emergency call device for carrying out the emergency call method.
  • Emergency call devices for motor vehicles are known, for example, under the English name eCall and are mandatory as basic equipment in new vehicles with EU type approval after March 31, 2018 for passenger cars and light commercial vehicles, see for example the EU press release of June 31, 2013 (https://ec .europa.eu/commission/presscorner/detail/de/IP_13_534).
  • the eCall system includes an in-vehicle communication device that is set up to establish a mobile phone connection to a control center automatically if an accident is detected in the vehicle, or at the user's initiative in the event of a medical emergency involving a vehicle occupant.
  • a so-called MSD minimal set of data
  • the control center can then initiate adequate assistance, including dispatching an emergency service to the scene of the accident or where the vehicle is located.
  • a voice connection can also be established between the vehicle user and the control center as part of the mobile phone connection, so that additional spoken help instructions can be given to the vehicle user.
  • the invention with the features of the independent patent claims improves an emergency call method for vehicle users and a vehicle emergency call device to the effect that the mediation of help positions by the control center on the part of the vehicle or to the vehicle user making an emergency call is facilitated, in particular their comprehensibility and perception by the vehicle user is improved.
  • vehicle emergency call device and the abbreviation emergency call device are used synonymously in connection with the present invention.
  • an emergency call method for vehicle users comprising the steps
  • the improved mediation of the help instructions generated on the part of the control center on the part of the vehicle or to the vehicle user or the vehicle user helping person is thus achieved in that the spoken help instructions in a textual help information, ie help information is converted into text form, which can then be displayed on an on-board display device. Furthermore, in addition to the display of the textual help information, the spoken help instructions can also be played back via a loudspeaker on the vehicle or on the emergency call device.
  • a voice message from the vehicle user is recorded or recorded and transmitted to the control center in addition to or as part of the emergency call message via the communication link.
  • the emergency message means that the voice message is recorded and transmitted to the control center as part of the emergency message or, for example, as an additional data packet to the emergency message.
  • the emergency call message includes the possibility of establishing a voice connection between the emergency call device and the control center or on the initiative of the control center in response to the received emergency call message between the control center and the emergency call device, so that the vehicle user can communicate verbally with the control center.
  • a voice connection has been established, a person helping the vehicle user can communicate directly verbally with the control center.
  • the spoken help instructions can be adapted in such a way that they are reliably and can be converted without misunderstandings, for example using simple language with short sentences and common vocabulary.
  • the spoken help instructions are converted into textual help information by the control center.
  • a speech-to-text conversion based on the current state of the art requires not inconsiderable computer resources, which are easier to maintain and operate in a control center than in or on a vehicle.
  • the speech-to-text conversion or the associated computer and software infrastructure would only have to be provided once in the control center or possibly multiple times for several intercom stations, while in the case of in-vehicle conversion, the infrastructure would have to be available in or on each individual vehicle . The latter option would obviously be significantly more expensive.
  • the spoken help instructions are preferably converted into textual help information by the control center when the vehicle type information transmitted to the control center indicates a motorcycle or two-wheeler.
  • the spoken help information can continue to be reproduced acoustically in the vehicle via a voice connection.
  • the spoken help instructions are converted into textual help information by the emergency call device. This relieves the control center of the task of converting speech-to-text.
