Abstract

A method and a device for acquiring, offering, and transmitting vehicle-based data of a route section, in particular environment data acquired by a vehicle of a vehicle swarm traveling on the route section and offered to a back-end computer and transmitted if required, comprising: reporting available vehicle-based data relating to the route section currently being traveled on to the back-end computer; requesting at least one selection of the vehicle-based data offered relating to the predefined route section from the vehicle by means of the back-end computer; collecting the requested selection of the vehicle-based data by means of the sensors of the vehicle and storing the data in a memory the vehicle; and transmitting the requested and collected data to the back-end computer.

First claim

What is claimed is:

1. A computer-implemented method for acquiring, offering, and transmitting vehicle-based sensor data of a route section, wherein the vehicle-based sensor data includes environment data acquired by a vehicle of a vehicle swarm traveling on the route section and offered to a back-end computer, comprising:
reporting, by a control circuit of the vehicle, available types of vehicle-based sensor data relating to the route section currently being traveled on to the back-end computer;
receiving, from the back-end computer, a request for at least one selected type of vehicle-based sensor data selected from the available types of vehicle-based sensor data reported by the control circuit of the vehicle, the request specifying at least one of a requested measuring frequency or a requested block length of at least one selected type of vehicle-based sensor data;
in response to the received request for the at least one selected type of vehicle-based sensor data, collecting, by at least one sensor associated with the at least one selected type of vehicle-based sensor data, vehicle-based sensor data in a memory of the vehicle; and
transmitting the requested and collected vehicle-based sensor data to the back-end computer.

2. A computer-implemented method for acquiring, offering, and transmitting vehicle-based sensor data of a route section, wherein the vehicle-based sensor data includes environment data acquired by a vehicle of a vehicle swarm traveling on the route section and offered to a back-end computer, comprising:
reporting, by a control circuit of the vehicle, available types of measured vehicle-based sensor data relating to the route section currently being traveled on to the back-end computer, wherein the measured vehicle-based sensor data are stored in a memory of the vehicle;
receiving, from the back-end computer, a request for at least one selected type of measured vehicle-based sensor data selected from the available types of measured vehicle-based sensor data reported by the control circuit of the vehicle, the request specifying at least one of a requested measuring frequency or a requested block length of the at least one selected type of measured vehicle-based sensor data;
in response to the received request for the at least one selected type of measured vehicle-based sensor data, collecting from the memory of the vehicle, measured vehicle-based sensor data of the at least one selected type of measured vehicle-based sensor data; and
transmitting the requested and collected measured vehicle-based sensor data to the back-end computer.

3. The method of claim 1 , wherein the requested and collected vehicle-based sensor data are transmitted at the request of the back-end computer.

4. The method of claim 1 , wherein the vehicle reports the availability of the requested and collected vehicle-based sensor data to the back-end computer, which requests the vehicle-based sensor data or ignores the report from the vehicle.

5. The method of claim 1 , wherein the vehicle-based sensor data collected in the vehicle are deleted in the vehicle after a predefined amount of time.

6. The method of claim 5 , wherein the deletion time for the vehicle-based sensor data that is determined by the predefined amount of time is determined on the basis of a storage capacity of the vehicle.

7. The method of claim 5 , wherein, in the event the back-end computer no longer needs the requested vehicle-based sensor data, the deletion time for the vehicle-based sensor data that is determined by the predefined amount of time is specified to the vehicle by the back-end computer.

8. The method of claim 1 , wherein the vehicle transmits information about available sensors of the vehicle to the back-end computer when reporting the available types of vehicle-based sensor data and the back-end computer makes a selection of the available types of vehicle-based sensor data based on the available sensors.

9. The method of claim 1 , wherein the vehicle logs in to a vehicle management system for communication with the back-end computer upon departure using its vehicle identification, wherein the vehicle management system either forms a separate unit or a component of the back-end computer.

10. A device for acquiring, offering, and transmitting vehicle-based sensor data of a route section, wherein the vehicle-based sensor data includes environment data acquired by a vehicle of a vehicle swarm traveling on the route section and offered to a back-end computer, comprising:
environment sensors for recording vehicle-based sensor data;
a data aggregator for storing and arranging the vehicle-based sensor data acquired by the environment sensors; and
a vehicle-based control circuit for controlling the data aggregator and for communication with the back-end computer, the control circuit configured to:
report available types of vehicle-based sensor data relating to the route section currently being traveled on to the back-end computer;
receive, via a bidirectional communication channel between the vehicle-based control circuit and the back-end computer, a request from the back-end computer for at least one selected type of vehicle-based sensor data selected from the available types of vehicle-based sensor data;
in response to the received request for the at least one selected type of vehicle-based sensor data, control the data aggregator to collect and aggregate vehicle-based sensor data collected by at least one of the environment sensors associated with the at least one selected type of vehicle-based sensor data; and
transmit, via a unidirectional communication channel between the vehicle-based control circuit and the back-end computer, the requested and collected vehicle-based sensor data to the back-end computer, wherein the unidirectional communication channel is distinct from the bidirectional communication channel.

11. The method of claim 2 , wherein the requested and collected vehicle-based sensor data are transmitted at the request of the back-end computer.

12. The method of claim 2 , wherein the vehicle reports the availability of the requested and collected vehicle-based sensor data to the back-end computer, which requests the vehicle-based sensor data or ignores the report from the vehicle.

13. The method of claim 2 , wherein the vehicle-based sensor data collected in the vehicle are deleted in the vehicle after a predefined amount of time.

14. The method of claim 3 , wherein the vehicle-based sensor data collected in the vehicle are deleted in the vehicle after a predefined amount of time.

15. The method of claim 4 , wherein the vehicle-based sensor data collected in the vehicle are deleted in the vehicle after a predefined amount of time.

16. The method of claim 13 , wherein the deletion time for the vehicle-based sensor data that is determined by the predefined amount of time is determined on the basis of a storage capacity of the vehicle.

17. The method of claim 13 , wherein the deletion time for the vehicle-based sensor data that is determined by the predefined amount of time is specified to the vehicle by the back-end computer.

18. The method of claim 2 , wherein the vehicle transmits information about available sensors of the vehicle to the back-end computer when reporting the available types of vehicle-based sensor data and the back-end computer makes a selection of the available types of vehicle-based sensor data based on the available sensors.
