Electronic communication device, related monitoring apparatus, supervision installation, communication method and computer program

1. An electronic communication device able to be coupled to a sensor and intended to be installed in the road infrastructure or embedded in a vehicle, the communication device comprising:

a determining module configured to determine a tracking list for at least one traffic element detected by the sensor, each tracking list including several information elements, the traffic element being located within a geographical zone covered by the sensor,

a computer configured to compute, as a function of at least one determined tracking list, a motion limitation setpoint for each vehicle located in the geographical zone; and

a transmitter configured to send the computed limitation setpoint(s) to an electronic supervision equipment item via a data link, the electronic supervision equipment item being able to remotely supervise, or remotely monitor, a fleet of the vehicle(s),

wherein the transmitter is configured to operate in a first sending mode according to which the transmitter transmits the computed limitation setpoint(s) to the electronic supervision equipment item.

2. The device according to claim 1 , wherein the communication device further comprises an acquisition module configured to acquire at least one setpoint computing rule, from an electronic apparatus; and

the computer is configured to compute the motion limitation setpoint further as a function of the at least one acquired computing rule.

3. The device according to claim 2 , wherein the electronic apparatus is the electronic supervision equipment item.

4. The device according to claim 1 , wherein the motion limitation setpoint is chosen from the group consisting of: a speed limitation setpoint; an acceleration limitation setpoint; and a speed and acceleration limitation setpoint.

5. The device according to claim 1 , wherein the determining module is configured to determine, for each traffic element, at least one information element chosen from the group consisting of:

the type of traffic element, such as pedestrian, stationary obstacle, motor vehicle or bicycle;

the position of the traffic element;

at least one dimension of the traffic element;

a speed of the traffic element;

an acceleration/deceleration of the traffic element; and

a confidence index associated with the traffic element.

6. The device according to claim 1 , wherein the communication device further comprises a switch configured to switch the transmitter between the first sending mode and a second sending mode according to which the transmitter transmits at least part of each tracking list to the electronic supervision equipment item.

7. The device according to claim 6 , wherein the switch is configured to evaluate a charge of the data link between the transmitter and the electronic supervision equipment item, and to switch the transmitter to the first sending mode if a charge of the data link is detected above a predefined charge threshold.

8. A monitoring apparatus comprising a sensor and an electronic communication device able to be coupled to said sensor, the communication device being according to claim 1 .

9. A supervision installation of a transport system including at least one motor vehicle, the supervision installation comprising:

at least a monitoring apparatus intended to be installed in the road infrastructure or on a corresponding motor vehicle; and

an electronic supervision equipment item coupled to each monitoring apparatus, the supervision equipment item being configured to transmit at least one instruction to a respective motor vehicle;

wherein at least one monitoring apparatus is according to claim 8 .

10. The supervision installation according to claim 9 , wherein the electronic supervision equipment item is configured to establish a resulting motion limitation setpoint for a geographical zone from one or several motion limitation setpoints received for said geographical zone.

11. A communication method implemented by an electronic communication device able to be coupled to a sensor and intended to be installed in the road infrastructure or embedded in a vehicle, the method comprising:

determining a tracking list for at least one traffic element detected by the sensor, each tracking list including several information elements, the traffic element being located within a geographical zone covered by the sensor,

computing, as a function of at least one determined tracking list, a motion limitation setpoint for each vehicle located in the geographical zone; and

sending the computed limitation setpoint(s) to an electronic supervision equipment item via a data link, the electronic supervision equipment item remotely supervising, or remotely monitoring, a fleet of the vehicle(s).

12. A non-transitory computer readable medium including a computer program including software instructions which, when implemented by a computer, implement a method according to claim 11 .
