Method and device for determining accident effects on a vehicle

1. A method for determining an accident effect on a vehicle, the method comprising:

repeatedly determining and storing movement data of the vehicle;

evaluating the movement data in order to detect an accident event and a secondary accident event, wherein the secondary accident event is due to the accident event causing a second impact of the vehicle against an obstacle; and

calculating at least one impact angle of an impact occurring external to the vehicle associated with both the accident event and the secondary accident event from the stored movement data following the detecting of the accident event and the secondary accident event,

wherein the movement data comprise velocity data and acceleration data,

wherein both the velocity data and the acceleration data are in at least two dimensions,

wherein the accident event and the secondary accident event are detected based on an absolute value of negative and positive movement data exceeding a predefined boundary value.

2. The method as recited in claim 1 , wherein the vehicle is a motor vehicle.

3. The method as recited in claim 1 , further comprising reconstructing from the stored movement data a movement sequence of the vehicle at least one of prior to and immediately after the accident event.

4. The method as recited in claim 1 , wherein the storing of the movement data includes storing the movement data for 5 min to 30 min.

5. The method as recited in claim 1 , wherein the storing of the movement data includes storing the movement data for 10 min to 15 min.

6. The method as recited in claim 1 , further comprising placing an emergency call upon detecting the accident event.

7. The method as recited in claim 1 , further comprising transmitting the movement data to a server upon detecting the accident event.

8. A device for determining an accident effect on a vehicle, comprising:

at least one motion sensor for detecting movement data of the vehicle;

at least one memory device for storing the movement data detected by the at least one motion sensor; and

an evaluation device for evaluating the movement data detected by the at least one motion sensor in order to detect an accident event and a secondary accident event, wherein the secondary accident event is due to the accident event causing a second impact of the vehicle against an obstacle, and to calculate at least one impact angle of an impact occurring external to the vehicle associated with both the accident event and the secondary accident event from the stored movement data following the detecting of the accident event and the secondary accident event, wherein the movement data comprise velocity data and acceleration data, wherein both the velocity data and the acceleration data are in at least two dimensions,

wherein the accident event and the secondary accident event are detected based on an absolute value of negative and positive movement data exceeding a predefined boundary value.

9. The device as recited in claim 8 , wherein the vehicle is a motor vehicle.

10. The device as recited in claim 8 , wherein the at least one motion sensor includes at least one of at least one velocity sensor and at least one acceleration sensor.

11. The device as recited in claim 8 , wherein the at least one memory device includes at least one circular buffer for temporarily storing the movement data detected by the at least one motion sensor.

12. The device as recited in claim 8 , further comprising a transmitter for, upon the detecting of the accident event, at least one of placing an emergency call and transmitting the movement data detected by the at least one motion sensor to a server.
