Abstract

A method and a device for transmitting vehicle-based environment data of a transportation vehicle travelling on a predetermined section of a road to a backend device for collecting data records relating to the specified section of the road, wherein the backend includes a master data backend and a vehicle data backend that are independent of each other, including registration of the transportation vehicle with the actual vehicle identification number with the master data backend via a wireless communication, transmitting a pseudo-vehicle identification number that is different from the actual vehicle identification number to the transportation vehicle on the part of the master data backend, wherein the allocation of the pseudo-vehicle identification number to the actual vehicle identification number is known outside the transportation vehicle exclusively to the master data backend, and submitting data records or summaries of data records to the vehicle data backend using the pseudo-vehicle identification number exclusively.

First claim

The invention claimed is:

1. A device for transmitting vehicle-based environment data of a transportation vehicle travelling on a predetermined section of road to a backend device for collecting data records relating to the specified section of the road, wherein the device comprises:
a transportation vehicle environment sensor arrangement;
a transportation vehicle data aggregator; and
a transportation vehicle communication device,
wherein a master data backend that generates a pseudo-vehicle identification number as a function of the actual transportation vehicle identification number of the transportation vehicle feeds the pseudo-vehicle identification number to the transportation vehicle that includes the device,
wherein a transportation vehicle data backend with which the transportation vehicle communicates exclusively with the pseudo-vehicle identification number, wherein the transportation vehicle data backend includes a communication device for communication with the transportation vehicle or transportation vehicles, a data handling device for processing the headers and data records of the transportation vehicle, a data request device for requesting data records via the master data backend, and an interface for communication with a customer
wherein the pseudo vehicle identification number is generated by application of a hash function to the transportation vehicle identification number so as to mask the actual transportation vehicle identification number in the master data backend and;
wherein the assignment of the pseudo-vehicle identification number to the actual transportation vehicle identification number is changed at predetermined time intervals.

2. The device of claim 1 , wherein the predetermined time interval is one day, half a day or at least 1 hour.

3. The device of claim 1 , wherein the assignment of the pseudo-vehicle identification number to the actual transportation vehicle identification number is changed at random time intervals.

4. The device of claim 3 , wherein the random time interval is at least 1 hour.

5. The device of claim 1 , wherein the transportation vehicle with the environment sensor arrangement generates data for the surroundings, summarizes the data into a current data record concerning the given route section as a function of the recording time in a data aggregator and generates a header related to the current data record, which is transferred together with the pseudo-vehicle identification number to the transportation vehicle data backend, where it is decided as a function of the header whether or not the corresponding data record is requested by the transportation vehicle data backend.

6. The device of claim 5 , wherein the request of the data record from the transportation vehicle data backend is fed to the master data backend using the pseudo-vehicle identification number, and the master data backend requests the transportation vehicle to transmit the requested data record to the transportation vehicle data backend using the transportation vehicle identification number, wherein this transmission to the transportation vehicle data backend is carried out using the pseudo-vehicle identification number.

7. The device of claim 6 , wherein the request for data records relating to a specified section of the route is made by a customer that communicates with the transportation vehicle data backend exclusively via an interface.

8. The device of claim 7 , wherein the customer determines the measurement parameters of the data record concerning a given section of the route, so that the transportation vehicle data backend determines whether corresponding data records are retrieved from the transportation vehicle or transportation vehicles and made available to the customer based on the headers supplied by the transportation vehicle or transportation vehicles.

9. A method for transmitting transportation vehicle-based environment data of a transportation vehicle travelling on a predetermined section of road to a backend device for collecting data records relating to the specified section of the road, wherein the backend device includes a master data backend and a transportation vehicle data backend that are independent of each other, the method comprising:
registering the transportation vehicle with the actual transportation vehicle identification number with the master data backend via a wireless communication;
transmitting a pseudo-vehicle identification number that is different from the actual transportation vehicle identification number to the transportation vehicle on the part of the master data backend, wherein the assignment of the pseudo-vehicle identification number to the actual transportation vehicle identification number is known outside the transportation vehicle exclusively to the master data backend; and
submitting data records or summaries of data records, so-called headers, to the transportation vehicle data backend using the pseudo-vehicle identification number exclusively
wherein the pseudo vehicle identification number is generated by application of a hash function to the transportation vehicle identification number so as to mask the actual transportation vehicle identification number in the master data backend and;
wherein the assignment of the pseudo-vehicle identification number to the actual transportation vehicle identification number is changed at predetermined time intervals.

10. The method of claim 9 , wherein the predetermined time interval is one day, half a day or at least 1 hour.

11. The method of claim 9 , wherein the assignment of the pseudo-vehicle identification number to the actual transportation vehicle identification number is changed at random time intervals.

12. The method of claim 11 , wherein the random time interval is at least 1 hour.

13. The method of claim 9 , wherein the transportation vehicle with the environment sensor arrangement generates data for the surroundings, summarizes the data into a current data record concerning the given route section as a function of the recording time in a data aggregator and generates a header related to the current data record, which is transferred together with the pseudo-vehicle identification number to the transportation vehicle data backend, where it is decided as a function of the header whether or not the corresponding data record is requested by the transportation vehicle data backend.

14. The method of claim 13 , wherein the request of the data record from the transportation vehicle data backend is fed to the master data backend using the pseudo-vehicle identification number, and the master data backend requests the transportation vehicle to transmit the requested data record to the transportation vehicle data backend using the transportation vehicle identification number, wherein this transmission to the transportation vehicle data backend is carried out using the pseudo-vehicle identification number.

15. The method of claim 13 , wherein the request for data records relating to a specified section of the route is made by a customer that communicates with the transportation vehicle data backend exclusively via an interface.

16. The method of claim 15 , wherein the customer determines the measurement parameters of the data record concerning a given section of the route, so that the transportation vehicle data backend determines whether corresponding data records are retrieved from the transportation vehicle or transportation vehicles and made available to the customer based on the headers supplied by the transportation vehicle or transportation vehicles.
