Abstract

The disclosure relates to system for uploading data from a main vehicle to a cloud server, comprising: a first sensor configured to obtain geo localization information of the main vehicle; a second sensor configured to monitor at least one predetermined characteristic of the main vehicle and/or of the environment of the man vehicle; a communication unit configured to transmit a report to an external cloud server and configured to receive network information from the external cloud server via a wireless communications network, said network information comprising at least one locally varying characteristic of the wireless communications network across a geographic region, and an electronic control unit configured to: repeatedly generate reports by collecting the at least one monitored characteristic and transmit them in predetermined time intervals via the communication unit, modify the predetermined time intervals as a function of the received network information and the obtained geo localization information.

First claim

The invention claimed is:

1. A system for uploading data from a main vehicle to a cloud server, comprising:
a first sensor configured to obtain geo localization information of the main vehicle;
a second sensor to monitor at least one predetermined characteristic of an environment of the main vehicle;
a communication unit configured to transmit a report to an external cloud server and configured to receive network information from the external cloud server via a wireless communications network, said network information comprising at least one locally varying characteristic of the wireless communications network across a geographic region, and
an electronic control unit configured to:
repeatedly generate reports by collecting the at least one monitored characteristic and transmit them in predetermined time intervals via the communication unit, and
modify the predetermined time intervals as a function of the received network information and the obtained geo localization information when the at least one locally varying characteristic indicates a reduced signal quality and a signal strength at a distance from the main vehicle below a predetermined distance threshold.

2. The system according to claim 1 , wherein the electronic control unit is configured to:
predict a reliability of the wireless communications network in an anticipated traveling direction of the main vehicle as a function of the received network information and the obtained geo localization information, and
modify the predetermined time intervals as a function of the predicted reliability.

3. The system according to claim 1 , wherein the electronic control unit is configured to shorten a current time interval until a next report is to be transmitted, in case the predicted reliability of the wireless communications network in an anticipated traveling direction is below a predetermined reliability threshold.

4. The system according to claim 1 , further comprising a data storage for storing street map data, wherein the electronic control unit is configured to anticipate a traveling direction of the main vehicle based on the street map data.

5. The system according to claim 1 , wherein the electronic control unit is configured to segment an anticipated traveling route of the main vehicle into a plurality of route segments, wherein the predetermined time intervals are defined such that at the end of each route segment a report is transmitted.

6. The system according to claim 5 , wherein a length of a route segment, in particular of a current route segment is changed as a function of the predicted reliability of the wireless communications network.

7. The system according to claim 1 , wherein the first sensor, the second sensor and the communication unit are installed in or on the main vehicle.

8. The system according to claim 1 , wherein at least one of the main vehicle or another vehicle is configured to repeatedly measure and report the at least one locally varying characteristic of the wireless communications network to the cloud server during traveling.

9. The system according to claim 1 , wherein the electronic control unit is installed in the main vehicle.

10. The system according to claim 1 , wherein the electronic control unit is external to the main vehicle.

11. The system according to claim 10 , wherein the electronic control unit is comprised by the external cloud server.

12. A method for uploading data from a main vehicle to a cloud server, the method comprising:
obtaining geo localization information of the main vehicle;
monitoring at least one predetermined characteristic of the environment of the main vehicle;
transmitting a report to an external cloud server and receiving network information from the external cloud server via a wireless communications network, said network information comprising at least one locally varying characteristic of the wireless communications network across a geographic region,
repeatedly generating reports by collecting the at least one monitored characteristic and transmitting them in predetermined time intervals via the communication unit, and
modifying the predetermined time intervals as a function of the received network information and the obtained geo localization information when the at least one locally varying characteristic indicates a reduced signal quality and a signal strength at a distance from the main vehicle below a predetermined distance threshold.

13. A vehicle comprising a system for uploading data from the vehicle to a cloud server, the system comprising:
a first sensor configured to obtain geo localization information of the vehicle;
a second sensor configured to monitor at least one predetermined characteristic of the environment of the vehicle;
a communication unit configured to transmit a report to an external cloud server and configured to receive network information from the external cloud server via a wireless communications network, said network information comprising at least one locally varying characteristic of the wireless communications network across a geographic region, and
an electronic control unit configured to:
repeatedly generate reports by collecting the at least one monitored characteristic and transmit them in predetermined time intervals via the communication unit, and
modify the predetermined time intervals as a function of the received network information and the obtained geo localization information when the at least one locally varying characteristic indicates a reduced signal quality and a signal strength at a distance from the main vehicle below a predetermined distance threshold.
