Abstract

A method includes receiving data corresponding to spaces situated in a street section, the data being ascertained by at least one ascertaining vehicle driving through the street section and including information corresponding to a beginning edge of at least one object and a ending edge of at least one second object, determining boundaries of at least one space in which parking is permitted based on the received data, and generating a display representation of the boundaries of the at least one space in which parking is permitted. The method includes receiving the data and determining the boundaries, for example, each time an ascertaining vehicle drives through the street.

First claim

What is claimed is:

1. A method comprising:
determining, by processing circuitry and based on received data that (a) correspond to spaces in a street section and (b) include information corresponding to a beginning edge of at least one object and an ending edge of at least one second object, at least one of a first boundary and a second boundary of a space in which parking is permitted; and
generating, by the processing circuitry, a display representation of the at least one of the first boundary and the second boundary of the space in which parking is permitted;
wherein:
the received data are ascertained using sensors situated on at least one ascertaining vehicle driving through the street section;
the received data includes:
1) a total number of detected beginning edges for a particular region of the street section;
2) a total number of detected ending edges for the particular region; and
3) a total number of detected edges for the particular region;

the determining of the at least one of the first boundary and the second boundary includes determining, for the particular region of the street section, a boundary variable (R) as

Σ Edge end represents the total number of detected ending edges in the particular region of the street section;
Σ Edge beginning represents the total number of detected beginning edges in the particular region of the street section; and
Σ Edge region represents the total number of detected edges in the particular region of the street section.

2. The method of claim 1 , wherein the receipt of the received data and the determining of the at least one of the first boundary and the second boundary is performed each time at least one of the at least one ascertaining vehicle drives through the street section.

3. The method of claim 1 , wherein the sensors are distance sensors.

4. The method of claim 3 , wherein the beginning edge of the at least one object is detected as a result of the distance sensors detecting a change in distance corresponding to a decrease in object distance from the at least one ascertaining vehicle.

5. The method of claim 3 , wherein the ending edge of the at least one second object is detected as a result of the distance sensors detecting an increase in object distance from the at least one ascertaining vehicle.

6. The method of claim 1 , wherein the first boundary is determined as a result of R being equal to approximately −1.

7. The method of claim 1 , wherein the second boundary is determined as a result of R being equal to approximately 1.

8. The method of claim 1 , wherein a region between the first boundary and the second boundary is determined as a result of R being equal to approximately 0.

9. The method of claim 1 , wherein the first boundary is determined as a result of R being equal to approximately −1, the second boundary is determined as a result of R being equal to approximately 1, and a region between the first boundary and the second boundary is determined as a result of R being equal to approximately 0.

10. A system comprising:
a data store;
a communication interface; and
a processing unit;
wherein:
the processing unit is configured to perform the following:
based on data that (a) are received via the communication interface from at least one ascertaining vehicle, (b) correspond to spaces in a street section, and (c) include information corresponding to a beginning edge of at least one object and an ending edge of at least one second object, determine at least one of a first boundary and a second boundary of a space in which parking is permitted; and
generate a display representation of the boundaries of the space in which parking is permitted;

the received data includes:
1) a total number of detected beginning edges for a particular region of the street section;
2) a total number of detected ending edges for the particular region; and
3) a total number of detected edges for the particular region;

the received data are ascertained using sensors situated on the at least one ascertaining vehicle driving through the street section;
the determining of the at least one of the first boundary and the second boundary includes determining, for the particular region of the street section, a boundary variable (R) as

Σ Edge end represents the total number of detected ending edges in the particular region of the street section;
Σ Edge beginning represents the total number of beginning edges in the particular region of the street section; and
Σ Edge region represents the total number of detected edges in the particular region of the street section.

11. The server system of claim 10 , wherein the processing unit is configured for receiving the received data and to perform the determination of the at least one of the first boundary and the second boundary is performed each time a vehicle drives through the street section.

12. The server system of claim 10 , wherein the sensors are distance sensors.

13. The server system of claim 12 , wherein the beginning edge of the at least one object is detected as a result of the distance sensors detecting a change in distance corresponding to a decrease in object distance from the ascertaining vehicle, and the ending edge is detected as a result of the dista
