Method and device for initiating an automatic emergency call
First Claim
1. A method for initiating an automatic emergency call by a controller, in which an emergency signal is initiated when an initiation threshold is reached based on sensor signals, the method comprising:
- initiating, by the controller, an emergency call when the initiation threshold is reached based on the sensor signals,assessing, by the controller, reliability of the sensor signalsdetermining, by the controller, a delay time based on the reliability of the sensor signals, the delay time and reliability having an inverse relationship with respect to each other, anddelaying transmission of the emergency call based on the determined delay time.

Abstract
A method and an apparatus for initiating an automatic emergency call wherein an emergency signal is sent when an initiation threshold is reached which is ascertained on the basis of a sensor signal. To prevent the incorrect transmissions of emergency calls and nevertheless to take account of a multiplicity of hazard situations, when the initiation threshold is reached an emergency call is initiated and additionally the reliability of the sensor signals prompting the initiation are assessed. When the sensor signals cannot be interpreted explicitly the emergency call is transmitted only after a delay time. During the delay time, the transmission of the emergency call can still be terminated.
