1. A method for placing an emergency call from a vehicle in an accident to a rescue co-ordination center by text-to-speech method, comprising the steps:
- detecting an accident of the vehicle by a sensor system of an automatic accident monitoring unit in the vehicle, and in response to a detected accident;
determining geographic accident co-ordinates of the vehicle by a positioning system,transmitting at least the accident co-ordinates to a central call unit processor, the central call unit processor correlating the accident coordinates with a digital map to determine a cartographic accident position as text information,converting the text information of the cartographic accident position into voice information by the central call unit processor, andtransmitting the voice information from the central call unit to the rescue co-ordination center over a voice channel,transmitting the voice information from the rescue coordination center to a rescue vehicle, andautomatically establishing, by the rescue coordination center, a voice channel between the vehicle in the accident and the rescue vehicle.

Abstract
An emergency call device for a vehicle is specified in which, on occurrence of a certain event, a data record is generated which thereupon is transmitted during the emergency call. The event can be an external request by an operator or a trigger signal inside a vehicle. In this way, the operator can obtain the most recent information at any time during the emergency call.

5. A system for placing an emergency call from a vehicle in an accident to a rescue co-ordination center by text-to-speech method, comprising:
-
a processor configured to; detect an accident of the vehicle by a sensor system, and in response to a detected accident determine the current geographic accident co-ordinates of the vehicle, transmit the accident co-ordinates to a central call unit processor for correlating the accident coordinates with a digital map stored there centrally, to obtain a cartographic accident position as text information which is converted by the central call unit processor into voice information in order to transmit the voice information over a voice channel to the rescue co-ordination center, wherein the rescue coordinator center transmits the voice information to a rescue vehicle, and automatically establishes a voice channel between the vehicle in the accident and the rescue vehicle. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
