Abstract

A method for detecting data of a vehicle operated at least partially in an automated manner, including at least one sensor, in particular, a surroundings sensor, in particular, a video sensor, a radar sensor, a LIDAR sensor, an ultrasonic sensor, an infrared sensor, and/or a GNSS sensor, in particular, for receiving a GPS signal, a GLONASS signal or a Galileo signal, and/or a vehicle sensor, in particular, for engine control, for activating occupant protection means, for activating assistance functions and/or convenience functions, in particular, an acceleration sensor, a rotation rate sensor, a pressure sensor, and at least one memory, in particular, a ring memory, including detecting data of the at least one sensor; saving the data in the memory, in particular, in the ring memory; detecting an event; initially storing the content of the memory, in particular, of the ring memory, at the point in time of the detected event.

First claim

What is claimed is:

1. A method for detecting data of a vehicle operated at least partially in an automated manner, the vehicle including at least one sensor and a ring memory, the method comprising:
detecting data of the at least one sensor;
saving the detected data in the ring memory, such that, after the ring memory is initially filled, each subsequent new data element of the detected data overwrites a respective earliest saved data element of the detected data that was previously saved in the ring memory;
detecting an event, wherein the event is an occurrence of a manual intervention by a driver of the vehicle that overrules or alters an action carried out by the vehicle in an automated manner; and
responsive to the detection of the event, transferring of all of the detected data that, due to the previous saving, fills an entirety the ring memory at a point in time of the detected event.

2. The method as recited in claim 1 , wherein the ring memory has a cycle time in which an entirety of the ring memory fills with the detected data, and wherein the method further comprises, responsive to the detection of the event, a second transferring of all of the detected data after passage of the cycle time subsequent to the point in time of the detected event.

3. The method as recited in claim 1 , wherein the transferring is to a cloud memory.

4. The method as recited in claim 1 , wherein the at least one sensor includes a surroundings sensor of the vehicle.

5. The method as recited in claim 1 , wherein the at least one sensor includes a video sensor, a radar sensor, a LIDAR sensor, an ultrasonic sensor, an infrared sensor, a GNSS sensor for receiving a GPS signal, a GLONASS signal, and/or a Galileo signal.

6. The method as recited in claim 1 , wherein the at least one sensor includes a vehicle sensor for engine control, a vehicle sensor for activating occupant protection devices, a vehicle sensor for activating assistance functions, a vehicle sensor for convenience functions, an acceleration sensor, a rotation rate sensor, and/or a pressure sensor.

7. The method as recited in claim 1 , wherein, based on the transferring, the action is not carried out in the automated manner in a different vehicle than the vehicle in which the manual intervention occurs.

8. A method for updating a scenario catalog, comprising:
responsive to a detection of an event of a vehicle, obtaining all detected sensor data of the vehicle that, due to a previous saving of the detected sensor data, fills an entirety of a ring memory, wherein the ring memory is operated such that, after the ring memory is initially filled, each subsequent new data element of the detected data overwrites a respective earliest saved data element of the detected data that was previously saved in the ring memory, wherein the event is an occurrence of a manual intervention by a driver of the vehicle that overrules or alters an action carried out by the vehicle in an automated manner;
ascertaining a probability of an occurrence of the detected event as a function of the obtained data; and
updating the scenario catalog using the ascertained probability and the detected event.

9. The method as recited in claim 8 , wherein based on the updating, the automated action is not performed in a different vehicle than the vehicle in which the manual intervention occurs.

10. The method as recited in claim 8 , wherein:
the ring memory has a cycle time in which an entirety of the ring memory fills with the detected sensor data; and
the method further comprises, responsive to the detection of the event, obtaining all further detected sensor data of the vehicle that fills the entirety of the ring memory after passage of the cycle time subsequent to the point in time of the detected event.

11. A non-transitory machine readable memory medium on which is stored a computer program for detecting data of a vehicle operated at least partially in an automated manner, the vehicle including at least one sensor and a ring memory, wherein the computer program is executable by a processor and, when executed by the processor, causes the processor to perform the following:
detecting data of the at least one sensor;
saving the detected data in the ring memory, such that, after the ring memory is initially filled, each subsequent new data element of the detected data overwrites a respective earliest saved data element of the detected data that was previously saved in the ring memory;
detecting an event, wherein the event is an occurrence of a manual intervention by a driver of the vehicle that overrules or alters an action carried out by the vehicle in an automated manner; and
responsive to the detection of the event, transferring of all of the detected data that, due to the previous saving, fills an entirety of the ring memory at a point in time of the detected event.

12. The non-transitory machine readable memory medium as recited in claim 11 , wherein:
the ring memory has a cycle time in which an entirety of the ring memory fills with the detected data; and
the computer program, when executed by the processor, causes the processor to perform, responsive to the detection of the event, a second transferring of all of the detected data after passage of the cycle time subsequent to the point in time of the detected event.

13. The non-transitory machine readable memory medium as recited in claim 11 , wherein, based on the transferring, the action is not carried out in the automated manner in a different vehicle than the vehicle in which the manual intervention occurs.

14. A device for detecting data of a vehicle that is operated at least partially in an automated manner and that includes at least one sensor, the device comprising:
a processor; and
a ring memory, wherein the processor is configured to:
obtain detected data of the at least one sensor;
save the detected data in the ring memory, such that, after the ring memory is initially filled, each subsequent new data element of the detected data overwrites a respective earliest saved data element of the detected data that was previously saved in the ring memory; and
in response to a detection of an event, transfer of all of the detected data that, due to the previous saving, fills an entirety of the ring memory at a point in time of the detected event, wherein the event is an occurrence of a manual intervention by a driver of the vehicle that overrules or alters an action carried out by the vehicle in an automated manner.

15. The device as recited in claim 14 , wherein the at least one sensor includes a surroundings sensor of the vehicle.

16. The device as recited in claim 14 , wherein the at least one sensor includes a video sensor, a radar sensor, a LIDAR sensor, an ultrasonic sensor, an infrared sensor, a GNSS sensor for receiving a GPS signal, a GLONASS signal, and/or a Galileo signal.

17. The device as recited in claim 14 , wherein the at least one sensor includes a vehicle sensor for engine control, a vehicle sensor for activating occupant protection devices, a vehicle sensor for activating assistance functions, a vehicle sensor for convenience functions, an acceleration sensor, a rotation rate sensor, and/or a pressure sensor.

18. The device as recited in claim 14 , wherein:
the ring memory has a cycle time in which an entirety of the ring memory fills with the detected data; and
the processor is further configured to, in response to the detection of the event, perform a second transfer of all of the detected data after passage of the cycle time subsequent to the point in
