Abstract

Techniques for automatically sending an emergency signal by means of a system of a vehicle are provided. According to one technique, an emergency situation is detected by evaluating signals of a number of sensors. A current position of the vehicle then determined, and a plurality of entries of emergency response services are received. A minimum cost is determined from the costs associated with respective entries of the plurality of entries to the current position of the vehicle, and a first-priority entry is determined from the minimum cost. An address for sending the emergency call signal is received, where the address is included in the first-priority entry. The retrieved address is used to start a setup of a connection to a device of the emergency response service.

Claims

1. A method for automatically sending an emergency call signal by a system of a vehicle, comprising:

Detecting an emergency situation by evaluating signals of a number of sensors;

Determining a current position of the vehicle by means of a position determining unit of the system;

Retrieving a plurality of entries of emergency response services from a database after the detection of the emergency situation;

Ascertaining a cost for each entry of the plurality of entries to the current position of the vehicle by means of a processor of the system;

Determining a minimum of costs;

Determining a first-priority entry, wherein the first-priority entry is determined from the minimum of costs;

Retrieving an address included in the first-priority entry for sending the emergency call signal; and

Starting a setup of a connection to a device of the emergency response service based on the retrieved address.

2. The method according to claim 1,

wherein the plurality of entries is a subset of a superset of entries of emergency response services;

and

wherein the subset is determined based on the signals of the number of sensors.

3. The method according to claim 1,

wherein a route and corresponding cost and/or flight distance and corresponding cost are calculated for the plurality of entries.

4. The method according to claim 1,

wherein a first route in a road network is determined at least for a first entry, and a second route in the road network is determined for a second entry;

and

wherein first cost based on the first route and second cost based on the second route and the minimum of first and second cost are determined.

5. The method according to claim 1,

wherein each cost is determined based on a risk factor, the risk factor depending on traffic congestion, transport availability and the like.

6. The method according to claim 1,

wherein a signal format of the emergency call signal is determined based on an identifier included in the first-priority entry.

7. The method according to claim 1,

wherein the entries of the emergency response services are updated by means of a memory or by means of a network connection to a server.

8. The method according to claim 1,

wherein a second-priority entry is ascertained;

wherein further address included in the second-priority entry for sending the emergency call signal is retrieved; and

wherein a further setup of a further connection to a further device of emergency response service by means of the further address is started if the setup of the connection to the receiving device of the first-priority entry is unsuccessful.

9. The method according to claim 1,

wherein a second-priority entry is ascertained;

wherein further address included in the second-priority entry for sending the emergency call signal is retrieved; and

wherein a further setup of a further connection to a further device of an emergency response service of the second-priority entry by means of the further address is started if an acknowledgement message is not received from the device of the emergency response service of the first-priority entry.

10. A system of a vehicle for sending an emergency call signal, comprising:

an interface for connecting a number of sensors for detecting an emergency situation based on signals of the number of sensors,

a position detecting unit for determining a current position of the vehicle,

a database for retrieving a plurality of entries of emergency response services,

a transceiver unit and

a processor;

wherein the processor is configured to;

determine a cost to the current position for each entry among the plurality of entries initiated by the detection of the emergency situation;

ascertain a minimum of costs;

determine a first-priority entry among the plurality of entries from the minimum of costs;

retrieve an address included in the first-priority entry for sending the emergency call signal;

start a setup of a connection to a device of the emergency response service by means of the retrieved address; and

wherein the transceiver unit is configured to send the emergency call signal via the connection.

11. A system of a vehicle for sending an emergency call signal, comprising:

an interface for connecting a number of sensors for detecting an emergency situation based on signals of the number of sensors;

an interface for connecting a position detecting unit for determining a current position of the vehicle;

an interface for connecting to a database containing a plurality of entries of emergency response services;

a transceiver unit; and

a processor;

wherein the processor is configured to;

retrieving a plurality of entries of emergency response services from a database after the detection of the emergency situation;

for the current position of the vehicle, determining an entry from the plurality of entries having a minimum cost relative to respective costs of other entries of the plurality of entries; and

initiating a connection to the emergency response service corresponding to the determined entry.
