Abstract

A method is provided for controlling traffic in a parking environment comprising at least one parking space and used by at least a first group of manually operated traffic participants and a second group of automatically operated traffic participants. A central control device by considering current status information of traffic participants as determined by sensors and/or transmitted by the traffic participants, determines instruction information for each traffic participant. The instruction information describes the future operation of each traffic participant in a common route planning for all traffic participants using the parking environment. The central control device transmits the instruction information, via a communication link, to at least one part of the traffic participants. The instruction information is used for outputting information and/or automatically controlling each traffic participant.

First claim

The invention claimed is:

1. A method for traffic control in a parking environment comprising at least one parking space and used by at least a first group of manually operated traffic participants and a second group of automatically operated traffic participants, the method comprising:
determining, for each traffic participant of the first and second groups of traffic participants, using a central control device and by considering current status information of the first and second groups of traffic participants as determined by sensors or received from the first and second groups of traffic participants, instruction information describing an operation of each traffic participant in a common route planning in the parking environment,
wherein priority values are associated to the first and second groups of traffic participants and the determining the instruction information comprises an optimization step such that a traffic participant of a group having a higher priority value is weighted more than a traffic participant of a group having a lower priority value, and
wherein a priority value for the second group of traffic participants is higher than a priority value for the first group of traffic participants; and
transmitting the instruction information, via a communication link, to at least a part of the first and second groups of traffic participants, wherein the instruction information is used for outputting information or automatically controlling each traffic participant.

2. The method of claim 1 , further comprising:
in response to a deviation of a traffic participant of one of the first group of traffic participants or the second group of traffic participants from its instruction information, adjusting an instruction information for at least one traffic participant of the other one of the first group of traffic participants or the second group of traffic participants based on a deviation information describing the deviation.

3. The method of claim 1 , further comprising:
in response to a deviation by a manually operated traffic participant from its instruction information, adjusting a trajectory to be travelled or a destination to be reached for at least an automatically operated traffic participant.

4. The method of claim 1 , further comprising:
in response to a deviation by an automatically operated traffic participant from its instruction information, adjusting a trajectory to be travelled or a destination to be reached for at least a manually operated traffic participant.

5. The method of claim 1 , further comprising:
in response to a deviation of a manually operated traffic participant from its instruction information or in response to impossibility of transmitting the instruction information of the manually operated traffic participant to the manually operated traffic participant, adjusting the instruction information of the manually operated traffic participant to block a current spatial operating area of the manually operated traffic participant.

6. The method of claim 1 , wherein when a manually operated traffic participant, according to its instruction information, follows an automatically operated traffic participant for at least one trajectory segment, the instruction information of the manually operated traffic participant comprises a follow-up operation.

7. The method of claim 1 , wherein an instruction information of a manually operated traffic participant is configured to adapt a steering system of the manually operated traffic participant for outputting a steering torque to a steering handle to output a hint torque, and the hint torque is opposed to a steering process that is in contrast to the instruction information of the manually operated traffic participant.

8. The method of claim 1 , further comprising:
controlling at least one traffic influencing device of the parking environment based on an instruction information of a manually operated traffic participant, wherein the manually operated traffic participant is not configured to receive the instruction information.

9. The method of claim 8 , wherein the at least one traffic influencing device comprises a traffic light, a barrier, or an information display device.

10. The method of claim 1 , wherein the parking environment is used by a third group of traffic participants comprising pedestrians, for which the instruction information is determined.

11. The method of claim 10 , further comprising:
controlling a traffic influencing device for directing a pedestrian according to an instruction information of the pedestrian, wherein the traffic influencing device comprises a traffic light, a barrier, an information display device, or a locking device for a door.

12. The method of claim 10 , further comprising:
transmitting an instruction information of a pedestrian to a mobile device of the pedestrian, wherein the mobile device is configured to create the communication link with the central control device and is configured to output information to the pedestrian.

13. The method of claim 10 , further comprising:
in response to a traffic participant of the first group of traffic participants or the second group of traffic participants deviating from its instruction information, adjusting an instruction information of a pedestrian and an instruction information of a traffic participant of the other one of the first group of traffic participants or the second group of traffic participants.

14. The method of claim 10 , further comprising:
in response to a traffic participant of the first group of traffic participants or the second group of traffic participants deviating from its instruction information, blocking a spatial area occupied by a pedestrian, which is determined according to a predicted trajectory of the pedestrian, for access by the first and second groups of traffic participants.

15. The method of claim 10 , wherein the priority values are associated to the first, second, and third groups of traffic participants.

16. The method of claim 15 , wherein the priority value for the second group of traffic participants is higher than a priority value for the third group of traffic participants.

17. The method of claim 15 , wherein a priority value of the third group of traffic participants is selected lower than the priority value of the first group of traffic participants and the priority value of the second group of traffic participants.

18. The method of claim 1 , wherein the determining the instruction information comprises considering time-dependent information, which describes an expected traffic.

19. The method of claim 18 , wherein the time-dependent information comprises statistically determined load information of the parking environment.

20. The method of claim 19 , wherein the statistically determined load information comprises information about the at least one parking space, an entrance route, or an exit route.
