Abstract

A vehicle includes a communication unit for the communication with an event management server, a navigation system for the output of at least one route, and a planning system. The planning system is configured to: a) retrieve a list, for a plurality of devices, particularly traffic light systems and/or signal groups of traffic light systems, the list including one identification respectively of the respective device and at least one position indication respectively of the respective device, b) compare the list with the route, in order to select at least one device from the list, c) for the subscription of events with respect to the selected device, send at least one subscription message to the event management server, the subscription message including the identifications of the selected devices.

Claims

1. A vehicle, comprising:

a communication unit that communicates with an event management server;

a navigation system that outputs at least one route;

a planning system, which is configured to;

a) retrieve a list for a plurality of devices, the list comprising one identification respectively of the respective device and at least one position indication respectively of the respective device;

b) compare the list with the route, in order to select at least one device from the list; and

c) for subscribing to events with respect to the selected device, send at least one subscription message to the event management server, the subscription message comprising the identifications of the selected devices.

2. The vehicle according to claim 1, wherein the plurality of devices are traffic light systems and/or signal groups of traffic light systems.

3. The vehicle according to claim 1, wherein:

the navigation system comprises a memory adapted to store a plurality of identifications and positions of devices, and

the list is provided at least partially by the navigation system.

4. The vehicle to according to claim 1, wherein

the planning system is further configured to:

d) receive an event message from the event management server;

e) process the event message and, based on the event message, predict a future event, which is assigned to one of the selected devices; and

f) communicate the future event and, if applicable, a point in time of the occurrence of the future event to a driver assistance system.

5. The vehicle according to claim 4, wherein the future event is a state of change of a device.

6. The vehicle according to claim 4, wherein:

the driver assistance system comprises a cruise control system, and

the cruise control system is designed to adapt a desired speed while taking into account the future event and/or the point in time of an occurrence of the future event.

7. The vehicle according to claim 1, wherein

the planning system is further configured to:

store a client subscription list which indicates at least some of the subscribed devices and/or events;

receive vehicle events with respect to a reached position and/or a new calculation of a route;

as a function of at least one vehicle event, send an unselection message to the event management server in order to terminate a subscription of an event.

8. A system, comprising:

an event management server, the event management server being configured to;

a) store a list of identifications which relate to devices;

b) receive subscription messages from a plurality of clients, an identification of a device and a sender address being assigned to the subscription messages;

c) select devices based on the subscription messages and store an assignment between the selected device and the respective sender address;

d) acquire at least one event that relates to one of the devices;

e) based on the stored assignments, select at least one client for the at least one event; and

f) send at least one event message to the selected client.

9. The system according to claim 8, wherein the plurality of clients are vehicles comprising a communication unit that communicates with the event management server, a navigation system that outputs at least one route, and a planning system configured to:

a) retrieve a list for a plurality of devices, the list comprising one identification respectively of the respective device and at least one position indication respectively of the respective device;

b) compare the list with the route, in order to select at least one device from the list; and

c) for subscribing to events with respect to the selected device, send at least one subscription message to the event management server, the subscription message comprising the identifications of the selected devices.

10. The system according to claim 9, wherein the storing of the assignment between the selected device and the respective sender address is stored in a server subscription list.

11. The system according to claim 9, wherein the devices are traffic light systems, signal groups, and/or signal transmitters, each comprising a control, wherein

the control is configured to, in an event of a current transition of state, determine a point in time of a future transition of state and communicate the current transition of state and the point in time of the future transition of state.

12. The system according to claim 11, wherein the future transition of state is an inverse of the current transition of state.

13. The system according to claim 11, further comprising a history database, in which a plurality of dwell time intervals for at least one device is stored, wherein

the event management server is configured to determine a dwell time for the device in a defined state while taking into account the dwell time intervals.

14. The system according to claim 8, wherein the event message comprises data indicating a future event and an occurrence point in time.

15. A method for forwarding events to a plurality of vehicles, each vehicle comprising

a communication unit that communicates with an event management server;

a navigation system that outputs at least one route;

a planning system, which is configured to;

a) retrieve a list for a plurality of devices, the list comprising one identification respectively of the respective device and at least one position indication respectively of the respective device;

b) compare the list with the route, in order to select at least one device from the list; and

c) for subscribing to events with respect to the selected device, send at least one subscription message to the event management server, the subscription message comprising the identifications of the selected devices,

the method comprising the acts of;

a) receiving at least one subscription message from at least one of the plurality of vehicles, an identification of a device and a sender address being assigned to the subscription message;

b) based on the subscription message, selecting a device from a list of devices;

c) storing an assignment of the vehicle to the selected device;

d) based on the stored assignment, forwarding an event which concerns the selected device to the assigned vehicle.

16. The method according to claim 15, further comprising the act of:

f) based on the stored assignment, forwarding data concerning a point in time of the occurrence of the future event to the assigned vehicle.

17. A computer product comprising a computer readable medium having stored thereon program instructions to carry out the method of claim 15.
