Abstract

A method of a control center for operating an automated transportation vehicle and an automated transportation vehicle allowing operation by the control center. The method includes reception of a request message for driving assistance and information on a traffic scenario of the automated transportation vehicle; determination by the control center at least one command for a maneuver of the automated transportation vehicle based on the traffic scenario and determination of a validity information for the at least one command, wherein the at least one command and/or the validity information is determined based on a channel quality; and submission of the at least one command and the validity information to the automated transportation vehicle.

First claim

The invention claimed is:

1 . A method of a control center for operating an automated transportation vehicle, the method comprising:
receiving a request message comprising a request for driving assistance and information on a traffic scenario of the automated transportation vehicle; determining at least one command for a maneuver of the automated transportation vehicle based on the traffic scenario and determining a validity information for the at least one command, wherein the at least one command and/or the validity information is determined based on a channel quality between the control center and the automated transportation vehicle, wherein the validity information is for a feasibility time of the at least one command, wherein the validity information for each command is determined as a difference of a time window of the maneuver of the command and a total of a duration of the maneuver and the latency, wherein the time window is based on the traffic scenario; and transmitting the at least one command and the validity information to the automated transportation vehicle to enable selection and performance by the automated transportation vehicle on an automated basis in response to receipt of the transmission of the at least one command and the validity information transmitted by the control center.

2 . The method of claim 1 , wherein the channel quality relates to a latency of a transmission of the request message and/or to a latency of a transmission of the at least one command.

3 . The method of claim 1 , wherein the channel quality relates to at least one of an error bit rate (BER) a signal to interference plus noise ratio (SINR) and a predicted Quality of Service (PQOS).

4 . The method of claim 1 , wherein the channel quality is related to a specific area and/or time.

5 . The method of claim 1 , wherein the communication between the control center and the automated transportation vehicle is performed via a mobile communication network.

6 . The method of claim 5 , wherein channel quality information is received periodically or as a single notification from at least one server of the mobile communication network.

7 . The method of claim 1 , wherein the validity information for each command is determined as a difference of a time window for the maneuver of the command and a duration of the maneuver, wherein the time window is based on the traffic scenario.

8 . The method of claim 1 , wherein the validity information for the feasibility time specifies a time length in which the at least one command has to be executed by the automated transportation vehicle and/or a time point until which the at least one command has to be executed by the automated transportation vehicle.

9 . The method of claim 7 , wherein the determining of at least one command comprises:
determining a set of commands based on the traffic scenario and determining the duration of the maneuver of every command in the set of commands; determining, for every maneuver, the time window based on the traffic scenario; and selecting the at least one command for which the validity information exceeds a predetermined threshold.

10 . The method of claim 9 , wherein selecting the at least one command further comprises selecting one of the at least one command that is providing the highest safety margin.

11 . An automated transportation vehicle comprising:
at least one first sensor configured to acquire ambient data; at least one second sensor configured to acquire vehicle data; a communication module configured for communication with a control center; and a controller configured for:
determination of a traffic scenario based on data received by the at least one first sensor and by the at least one second sensor;
transmission of a request message comprising a request for driving assistance and information on the traffic scenario to the control center via the communication module;
receipt of at least one command and validity information for the at least one command from the control center via the communication module, wherein the at least one command and/or the validity information is based on a channel quality for communication between the control center and the automated transportation vehicle, wherein the validity information relates to a feasibility time of the at least one command, wherein the communication between the control center and the automated transportation vehicle is performed via a mobile communication network, wherein channel quality information is received periodically or as a single notification from at least one server of the mobile communication network, wherein the validity information for each command is determined as a difference of a time window of the maneuver of the command and a total of a duration of the maneuver and the latency, wherein the time window is based on the traffic scenario;
determination of a feasibility of the at least one command based on the validity information;
selection of one of the at least one command based on the determined feasibility; and
performance of the selected command on an automated basis in response to the command selection.

12 . The automated transportation vehicle of claim 11 , wherein the controller is further configured to determine a time of feasibility from the validity information and to select the one command with the largest feasibility time and/or for discarding any command with a feasibility time being below a predetermined threshold.

13 . The automated transportation vehicle of claim 12 , wherein the controller is further configured to determine a latency of the communication with the control center and to determine the feasibility time based on the validity information and the determined latency.

14 . The automated transportation vehicle of claim 12 , wherein the controller is further configured to send a new request message to the control center in response to the feasibility of each of the at least one command being insufficient.

15 . The automated transportation vehicle of claim 11 , wherein the channel quality relates to a latency of a transmission of the request message and/or to a latency of a transmission of the at least one command.

16 . The automated transportation vehicle of claim 15 , wherein the validity information for the feasibility time specifies a time length in which the at least one command has to be executed by the automated transportation vehicle and/or a time point until which the at least one command has to be executed by the automated transportation.

17 . The automated transportation vehicle of claim 11 , wherein the channel quality relates to at least one of an error bit rate (BER) a signal to interference plus noise ratio (SINR) and a predicted Quality of Service (PQOS).

18 . The automated transportation vehicle of claim 11 , wherein the channel quality is related to a specific area and/or time.

19 . The automated transportation vehicle of claim 11 , wherein the communication between the control center and the automated transportation vehicle is performed via a mobile communication network.

20 . The automated transportation vehicle of claim 19 , wherein channel quality information is received periodically or as a single notification from at least one server of the mobile communication network.

21 . The automated transportation vehicle of claim 20 , wherein the determination of the at least one command comprises:
determination of a set of commands based on the traffic scenario and determining
