Abstract

A parking guidance apparatus according to an embodiment comprises: a storage unit for storing parking state information of a parking slot within a predetermined space; a communication unit for receiving, from a first vehicle, occupancy state information 0 of at least a part of the parking slot in the predetermined space; an update unit for updating the parking state information by using the received occupancy state information; and a control unit for, when the parking state information for the predetermined space is requested by a second vehicle through the communication unit, providing the second vehicle with a parking slot, which is in a parking-available state, determined on the basis of the updated parking state information.

First claim

What is claimed is:

1. A parking guidance apparatus comprising:
a storage configured to store parking state information of a parking slot within a predetermined space;
a transceiver configured to receive, from a first vehicle, occupancy state information of at least one of the parking slot in the predetermined space; and
a processor configured to update the parking state information by using the received occupancy state information, and provide a second vehicle with a parking slot, which is in a parking-available state, determined based the updated parking state information when the transceiver receives a request for a parking slot guidance for the predetermined space from a second vehicle,
wherein the transceiver is further configured to receive occupancy state information of a first parking slot where the first vehicle parks or leaves and occupancy state information of a second parking slot where the first vehicle detects near the first parking slot,
wherein the processor is further configured to update, when the transceiver receives the occupancy state information of the second parking slot, the parking state information of the second parking slot by using a difference between the accumulated number of the occupancy states and the accumulated number of the inoccupancy states of the second parking slot from a time when the parking state information of the second parking slot is initialized, and
wherein the processor is further configured to determine whether the second parking slot is in a parking-available state based on the difference between the accumulated number of the occupancy states and the accumulated number of the inoccupancy states of the second parking slot.

2. The parking guidance apparatus of claim 1 , wherein the processor is further configured to initialize, when the transceiver receives the occupancy state information of the first parking slot, parking state information of the first parking slot to parking state information corresponding to the received occupancy state information of the first parking slot.

3. The parking guidance apparatus of claim 1 , wherein the processor is further configured to provide, to the second vehicle, a parking slot in a parking-available state determined based on the updated parking state information if the predetermined space is located within a predetermined range from a destination of the second vehicle.

4. A parking guidance method performed by a vehicle, the parking guidance method comprising:
obtaining first occupancy state information of a first parking slot where the vehicle parks or leaves;
obtaining second occupancy state information of a second parking slot sensed by the vehicle while driving to or from the first parking slot;
transmitting, to a parking guidance apparatus, at least one of the first occupancy state information and the second occupancy state information, causing the parking guidance apparatus to update parking state information of each parking slot stored in the parking guidance apparatus;
transmitting, to the parking guidance apparatus, a request for guidance on parking for a destination;
receiving, from the parking guidance apparatus, parking-available states on a plurality of parking slots in a parking space corresponding to the destination;
generating first routes from the destination to each of a subset of parking slots in the parking-available states; and
determining a final parking slot according to traveling times of the generated first routes.

5. The parking guidance method of claim 4 , wherein the vehicle comprises a sensing device including at least one of a radar, a LiDAR, a camera, and an ultrasonic sensor, and wherein the obtaining the second occupancy state information is obtaining the second occupancy state information of the second parking slot within the sensing area of the sensing device.

6. The parking guidance method of claim 4 further comprising:
receiving, from the parking guidance apparatus, a plurality of parking slots in the parking-available states updated after completing parking if a traveling time from the determined final parking slot to the destination is greater than or equal to a threshold value after completing the parking.

7. The parking guidance method of claim 6 , further comprising:
generating a second route from each of the plurality of the updated parking slots to the destination; and
changing the final parking slot based on a traveling time according to the second routes.

8. A non-transitory computer-readable storage medium including computer executable instructions, wherein the instructions, when executed by a processor, cause the processor to perform a parking guidance method, the method comprising:
obtaining first occupancy state information of a first parking slot where a vehicle parks or leaves;
obtaining second occupancy state information of a second parking slot sensed by the vehicle while driving to or from the first parking slot;
transmitting, to a parking guidance apparatus, at least one of the first occupancy state information and the second occupancy state information, causing the parking guidance apparatus to update parking state information of each parking slot stored in the parking guidance apparatus;
transmitting, to the parking guidance apparatus, a request for guidance on parking for a destination;
receiving, from the parking guidance apparatus, parking-available states on a plurality of parking slots in a parking space corresponding to the destination;
generating first routes from the destination to each of a subset of parking slots in the parking-available states; and
determining a final parking slot according to traveling times of the generated first routes.

9. The non-transitory computer-readable recording medium of claim 8 , wherein the second occupancy state information of the second parking slot is obtained by at least one of a radar, a LiDAR, a camera, and an ultrasonic sensor included in the vehicle.

10. The non-transitory computer-readable recording medium of claim 8 , the method further comprising:
receiving, from the parking guidance apparatus, a plurality of parking slots in the parking-available states updated after completing parking if a traveling time from the determined final parking slot to the destination is greater than or equal to a threshold value after completing the parking.

11. The non-transitory computer-readable recording medium of claim 10 , the method further comprising:
generating a second route from each of the plurality of the updated parking slots to the destination; and
changing the final parking slot based on a traveling time according to the generated second routes.
