Abstract

A method of providing parking information for autonomous parking, may include receiving, by an autonomous driving vehicle based on a connected car entering a parking lot, pieces of global positioning system (GPS) information for a driving route in the parking lot from the connected car, configuring a map of the parking lot on the basis of the received pieces of GPS information, and providing a driving route on the map of the parking lot according to a request of the autonomous driving vehicle entering the parking lot, wherein the driving route is selected by a weight value assigned to each route on the map of the parking lot.

First claim

What is claimed is:

1. A method of providing parking information for autonomous parking, comprising:
receiving, by an autonomous driving vehicle based on a connected car entering a parking lot, pieces of global positioning system (GPS) information for a plurality of driving routes in the parking lot from the connected car;
configuring a map of the parking lot on the basis of the received pieces of GPS information;
assigning a low weight value to a driving route of the plurality of driving routes on the map after a predetermined amount of time;
assigning a high weight value to each of the plurality of driving routes on the map when an amount of the pieces of GPS information collected from the connected car becomes larger;
selecting the driving route having the low weight value on the map according to a request of the autonomous driving vehicle entering the parking lot; and
providing the selected driving route to the autonomous driving vehicle.

2. The method of claim 1 , further comprising:
selecting the selected driving route by excluding the driving route having the low weight value in which an obstacle is detected on the map.

3. The method of claim 1 , further comprising:
selecting a position farthest away from an entrance of the parking lot as a waypoint on the selected driving route, and selecting the waypoint as a next destination.

4. The method of claim 1 , further comprising:
additionally assigning a weight value to the selected driving route on the map where the autonomous driving vehicle passes.

5. The method of claim 1 , further comprising:
selecting the selected driving route by excluding a driving route of the plurality of driving routes on the map, which is adjacent to an entrance and an exit of the parking lot.

6. A service server for providing parking information for autonomous parking, the service server comprising:
a memory configured to store:
pieces of global positioning system (GPS) information for a plurality of driving routes in a parking lot, which are received from an autonomous driving vehicle based on a connected car entering a parking lot; and
a map of the parking lot which is configured on the basis of the received pieces of GPS information; and

a processor configured to execute instructions stored in the memory and to:
assign a low weight value to a driving route of the plurality of driving routes on the map after a predetermined amount of time;
assign a high weight value to each of the plurality of driving routes on the map when an amount of the pieces of GPS information collected from the connected car becomes larger;
select the driving route having the low weight value on the map, which is provided to the connected car according to a request of the connected car entering the parking lot; and
provide the selected driving route to the connected car entering the parking lot.

7. The service server of claim 6 , wherein the processor is configured to select the selected driving route by excluding the driving route having the low weight value in which an obstacle is detected on the map.

8. The service server of claim 6 , wherein the processor is configured to:
select a position farthest away from an entrance of the parking lot as a waypoint on the selected driving route, and
select the waypoint as a next destination.

9. The service server of claim 6 , wherein a weight value is additionally assigned to the selected driving route on the map where the autonomous driving vehicle passes.

10. The service server of claim 6 , wherein the processor is configured to select the selected driving route by excluding a driving route of the plurality of driving routes on the map, which is adjacent to an entrance and an exit of the parking lot.

11. A system for providing parking information for autonomous parking, the system comprising:
a connected car configured to enter a parking lot and transmit pieces of global positioning system (GPS) information for a plurality of driving routes in the parking lot; and
a service server configured to provide parking information for autonomous parking by configuring a map of the parking lot on the basis of the pieces of GPS information received from the connected car;
assigning a low weight value to a driving route of the plurality of driving routes on the map after a predetermined amount of time;
assigning a high weight value to each of the plurality of driving routes on the map when an amount of the pieces of GPS information collected from the connected car becomes larger;
selecting a driving route having the low weight value of the plurality of driving routes on the map of the parking lot; and
providing the selected driving route to the connected car entering the parking lot.
