Method, Computer Program Product, and Electronic Control Device for Locating a Parking Space for Vehicles

摘要

To find a parking space for a vehicle in a target area, a connection server stores connection data associated with the target area for a plurality of data servers. A search request to find a parking space in the target area is addressed to the connection server. The connection server uses the association data to establish a connection to the data servers and, in the process, queries whether availability data relating to available parking spaces in the target area are stored in the respective database. In a first query stage, the data servers are preselected, in which case first parking space data based on the target area are requested by the connection server and corresponding first feedback data from the data servers are used to respond whether the respective data server contains parking space data relating to the target area. Based on the first feedback data, the connection server decides which of the respective data servers are preselected, and at least one data server is selected as a selection server, and second feedback data, more detailed than the respective first feedback data, are respectively retrieved in a second query stage of the selection server.

1. A method for finding a parking space for a vehicle in a target area, the method comprising the acts of:
storing, in a connection server, connection data associated with the target area for a plurality of data servers, each of which store data relating to at least one parking space; receiving, by the connection server, a search request from the vehicle to find a parking space in the target area; establishing a connection to the plurality of data servers, by the connection server, using the connection data associated with the target area for the plurality of data servers, and querying whether availability data relating to available parking spaces in the target area are stored in a respective database and, if availability data are available, receiving feedback data transmitted by the respective data servers to the connection server; and wherein the act of querying by the connection server is carried out in multiple stages such that:
in a first query stage, the data servers are preselected, in which case first parking space data based on the target area are requested by the connection server and corresponding first feedback data received from the data servers are used to respond whether the respective data server contains parking space data relating to the target area;based on the first feedback data, the connection server decides which of the respective data servers are preselected; andat least one of the data servers is selected from the preselected data servers as a selection server, and second feedback data, which are more detailed than the respective first feedback data at least in terms of parking space location, are respectively retrieved in a second query stage with respect to the selection server.
