Electronic device and method for monitoring a set of autonomous motor vehicles, associated transport system and computer program

1. An electronic device for monitoring a set of autonomous motor vehicles, the device comprising:

a detection module configured to detect an event associated with a plurality of vehicles from among the set of autonomous motor vehicles;

a calculating module configured to calculate, as a function of the detected event, a setpoint for limiting the movement for each vehicle of said plurality of vehicles; and

a transmission module configured to transmit the calculated setpoint(s) to the plurality of vehicles associated with the detected event,

wherein the transmission module is configured to transmit, to the plurality of vehicles associated with the detected event, a command message for commanding a limitation of the movement of the vehicle, said command message including the calculated setpoint, and

wherein the calculating module is configured to calculate each setpoint for limiting the movement via a selection, as a function of an intensity of the detected event, of a level from among several setpoint levels.

2. The device according to claim 1 , wherein the calculating module is configured to calculate a single setpoint for limiting the movement for the plurality of vehicles.

3. The device according to claim 2 , wherein the transmission module is configured to transmit, to the plurality of vehicles associated with the detected event, a single command message for commanding a limitation of the movement of the vehicle, said command message including the calculated setpoint,

wherein the command message is a single message for the plurality of vehicles associated with the detected event.

4. The device according to claim 1 , wherein the setpoint limiting the movement includes a limitation of the speed of the vehicle and/or a limitation of the variation of the speed of the vehicle.

5. The device according to claim 1 , wherein the event detected by the detecting module is chosen from among the group consisting of: a weather event, a high density of traffic elements and an attack against the plurality of vehicles.

6. The device according to claim 5 , wherein a maximum setpoint level corresponds to a stop of the vehicle.

7. The device according to claim 5 , wherein the setpoint values associated with the setpoint levels depend on a type of the detected event.

8. The device according to claim 7 , wherein the type of the detected event is chosen from among the group consisting of: a type of weather event; an abnormal density of traffic elements; and a type of attack.

9. The device according to claim 8 , wherein the type of weather event is chosen from among the group consisting of: fog; ice; snow; rain; and wind.

10. The device according to claim 8 , wherein the type of attack is chosen from among the group consisting of: a cyberattack; and a terrorist attack.

11. A transport system comprising a set of autonomous motor vehicles and an electronic monitoring device configured to monitor said set of autonomous motor vehicles, the electronic monitoring device being according to claim 1 .

12. A method for monitoring a set of autonomous motor vehicles, the method being carried out by an electronic monitoring device and comprising:

detecting an event associated with a plurality of vehicles from among the set of autonomous motor vehicles;

calculating, as a function of an intensity of the detected event, of a level from among several setpoint levels, a setpoint for limiting the movement via a selection for each vehicle of said plurality of vehicles; and

transmitting a command message for commanding a limitation of the movement of the vehicle, said command message including the calculated setpoint(s) to the plurality of vehicles associated with the detected event.

13. A non-transitory computer-readable medium including a computer program comprising software instructions which, when executed by a computer, carry out a method according to claim 12 .
