Abstract

A method is disclosed for identifying an appropriate parking space for a motor and a route leading thereto for a motor vehicle having a navigation system, wherein at least one collision-free route is calculated on the basis of at least one piece of information that is related to a search for a parking space and that is requested from at least one external server, which manages at least one parking lot having at least one parking space, before the motor vehicle reaches the parking lot. A motor vehicle with a navigation system and an external server, for execution of the method, are also disclosed.

Claims

1-10. -10. (canceled)

11. A method for identifying an appropriate parking space for a motor vehicle and a route leading thereto, comprising:

requesting, by a navigation system in the motor vehicle, of a piece of information regarding a parking place search from an external server that manages a parking lot having at least one parking space, before the parking lot is reached;

sending the piece of information requested from the external server to the navigation system in the motor vehicle;

executing, by the navigation system, a route search from a start node to a destination node, in which an initial basic reachability verification for the destination node from the start node is determined;

identifying a route section that is required in order to reach the destination node from the start node;

executing a second reachability verification that is more detailed in at least one testing characteristic than the initial reachability verification, and a specific suitability test for at least one parameter of the motor vehicle of the at least one parking space in the parking lot;

loading a detailed route section identified from the external server to the navigation system in the motor vehicle; and

calculating a collision-free route from the start node to the destination node.

12. The method of claim 11, wherein a current location of the motor vehicle or a point of arrival to the parking lot determined by the navigation system is used as the start node.

13. The method of claim 11, wherein the at least one parking space or a desired target position for the motor vehicle within the at least one parking space is used as the destination node.

14. The method of claim 13, wherein the target position within the at least one parking space is determined on the basis of the detailed route section, a geometric factor, a position of a loading ramp, a position of a charging device, or a user preference.

15. The method of claim 11, wherein the detailed route section includes a geometry of the road, a reference path, a localization of the route section in the parking lot, a sensor modality, the at least one parking space, an item of fleet data, an impediment, or an available room to maneuver.

16. The method of claim 11, wherein a navigation of the collision-free route can occur semi-autonomously, autonomously, or manually.

17. The method of claim 11, wherein the request from the navigation system includes at least one filter criterion that is specific to the motor vehicle.

18. The method of claim 11, wherein the piece of information to be transmitted to the navigation system in the motor vehicle is pre-filtered by the external server in accordance with at least one specific property of the motor vehicle.

19. A method for navigating a motor vehicle comprising the steps of:

requesting a piece of information regarding a parking place search from an external server that manages a parking lot having at least one parking space, before the parking lot is reached, wherein the request may include at least one filter criterion specific to the motor vehicle;

receiving the piece of information requested from the external server;

determining, and using as a start node, a current location of the motor vehicle or a point of arrival to the parking lot;

determining, and using as a destination node, the at least one parking space or a desired target position for the motor vehicle within the at least one parking space;

executing a route search from the start node to the destination node, in which an initial basic reachability verification for the destination node from the start node is determined by the external server;

identifying a route section that is required in order to reach the destination node from the start node;

requesting the external server to execute a second reachability verification that is more detailed in at least one testing characteristic than the initial reachability verification, and a specific suitability test for at least one parameter of the motor vehicle of the at least one parking space in the parking lot;

loading a detailed route section identified from the external server to the navigation system in the motor vehicle; and

calculating a collision-free route from the start node to the destination node.

20. The method of claim 19, wherein a navigation of the collision-free route can occur semi-autonomously, autonomously, or manually.

21. A method for communicating between an external server and a navigation system in a motor vehicle, wherein the external server manages a parking lot having at least one parking space, by performing the steps of:

receiving from the navigation system of the motor vehicle a request for a piece of information regarding a parking place search before the parking lot is reached by the motor vehicle;

sending the piece of information requested from the external server to the navigation system in the motor vehicle;

using as a start node a current location of the motor vehicle or a point of arrival to the parking lot;

using as a destination node the at least one parking space or a desired target position for the motor vehicle within the at least one parking space;

executing an initial basic reachability verification for the destination node from the start node;

identifying a route section that is required in order to reach the destination node from the start node;

executing a second reachability verification that is more detailed in at least one testing characteristic than the initial reachability verification, and a specific suitability test for at least one parameter of the motor vehicle of the at least one parking space in the parking lot; and

providing to the navigation system in the motor vehicle a detailed route section identified by the external server.

22. The method of claim 21, wherein the request from the navigation system of the motor vehicle for the piece of information regarding the parking place search includes at least one filter criterion specific to the motor vehicle.

23. The method of claim 22, wherein the piece of information to be transmitted to the navigation system in the motor vehicle is pre-filtered by the external server in accordance with at least one specific property of the motor vehicle.

24. The method of claim 21, wherein the external server sends information identifying available parking spaces to the navigation system in the motor vehicle.
