Abstract

An electronic device for a vehicle includes a power supply configured to supply power, an interface configured to receive high-definition (HD) map data of a specified region from a server through a communication device and to receive traveling situation information of the vehicle, and at least one processor configured to continuously generate electronic horizon data of the specified region based on the HD map data in a state in which the power is received, and to adjust a speed of reception of the HD map data based on the traveling situation information.

First claim

What is claimed:

1. An electronic device for a vehicle, comprising:
a power supply configured to supply power;
an interface configured to receive, from a server through a communication device, high-definition (HD) map data of a specified region and to receive traveling situation information of the vehicle; and
at least one processor configured to:
continuously generate electronic horizon data of the specified region based on the HD map data in a state in which the power is received, and
adjust a speed of reception of the HD map data based on the traveling situation information,

wherein, based on a traveling speed of the vehicle being equal to or greater than a reference speed, the at least one processor is configured to increase a geographic range of the HD map data and receive the HD map data through a first communication method,
wherein, based on the traveling speed of the vehicle being less than the reference speed, the at least one processor is configured to reduce the geographic range of the HD map data and receive the HD map data through a second communication method, and
wherein the speed of reception of the HD map data in the first communication method is greater than the speed of reception of the HD map data in the second communication method.

2. The electronic device of claim 1 , wherein the at least one processor adjusts a bandwidth for receiving the HD map data based on the traveling situation information.

3. The electronic device of claim 1 , wherein the at least one processor adjusts the geographic range of the HD map data based on the traveling situation information.

4. The electronic device of claim 1 , wherein the at least one processor adjusts the speed of reception of the HD map data based on at least one of autonomous driving state information, manual driving state information, traveling speed information, parking operation situation information, stop situation information, or vehicle position information.

5. The electronic device of claim 1 , wherein the at least one processor generates the electronic horizon data based on at least one of autonomous driving state information, manual driving state information, traveling speed information, parking operation situation information, stop situation information, or vehicle position information.

6. The electronic device of claim 1 , wherein the at least one processor is configured to, based on the traveling speed of the vehicle being equal to or greater than the reference speed, increase a length of horizon path included in the electronic horizon data, and
wherein the at least one processor is configured to, based on the traveling speed of the vehicle being less than the reference speed, reduce the length of horizon path included in the electronic horizon data.

7. A method of operating an electronic device for a vehicle, the method comprising:
receiving power by at least one processor;
receiving data of traveling situation information of the vehicle in a state in which the power is received, by the at least one processor;
adjusting a speed of reception of high-definition (HD) map data based on the traveling situation information in a state in which the power is received, by the at least one processor;
receiving, from a server through a communication device in the state in which the power is received, HD map data of a specified region depending on the reception speed, by the at least one processor; and
generating electronic horizon data corresponding to a geographic range based on the HD map data in the state in which the power is received, by the at least one processor,
wherein adjusting the speed of reception of the HD map data comprises:
based on a traveling speed of the vehicle being equal to or greater than a reference speed, increasing a geographic range of the HD map data and receiving the HD map data through a first communication method, by the at least one processor,
based on the traveling speed of the vehicle being less than the reference speed, reducing the geographic range of the HD map data to be reduced and receiving the HD map data through a second communication method, by the at least one processor, and

wherein the speed of reception of the HD map data in the first communication method is greater than the speed of reception of the HD map data in the second communication method.

8. The method of claim 7 , wherein the adjusting comprises adjusting a bandwidth for receiving the HD map data based on the traveling situation information by the at least one processor.

9. The method of claim 7 , wherein the adjusting comprises adjusting a geographic range of the HD map data based on the traveling situation information.

10. The method of claim 7 , wherein the adjusting comprises adjusting a speed of reception of the HD map data based on at least one of autonomous driving state information, manual driving state information, traveling speed information, parking operation situation information, stop situation information, or vehicle position information.

11. The method of claim 7 , wherein the generating comprises generating the electronic horizon data based on at least one of autonomous driving state information, manual driving state information, traveling speed information, parking operation situation information, stop situation information, or vehicle position information.

12. The method of claim 7 , wherein adjusting the speed of reception of the HD map data comprises:
based on the traveling speed of the vehicle being equal to or greater than the reference speed, increasing a length of horizon path included in the electronic horizon data, and
based on the traveling speed of the vehicle being less than the reference speed, reducing the length of horizon path included in the electronic horizon data.

13. A system comprising:
a server configured to provide high-definition (HD) map data; and
at least one vehicle comprising an electronic device configured to receive the HD map data, wherein the electronic device comprises:
a power supply configured to supply power;
an interface configured to receive HD map data of a specified region from a server through a communication device; and
at least one processor configured to:
continuously generate electronic horizon data of the specified region based on the HD map data in a state in which the power is received, and
adjust a speed of reception of the HD map data based on traveling situation information of the vehicle,

wherein, based on a traveling speed of the vehicle being equal to or greater than a reference speed, the at least one processor is configured to increase a geographic range of the HD map data and receive the HD map data through a first communication method,
wherein, based on the traveling speed of the vehicle being less than the reference speed, the at least one processor is configured to reduce the geographic range of the HD map data and receive the HD map data through a second communication method,
wherein the speed of reception of the HD map data in the first communication method is greater than the speed of reception of the HD map data in the second communication method.

14. The system of claim 13 , wherein the at least one processor generates a signal for adjusting a bandwidth for receiving the HD map data based on the traveling situation information.

15. The system of claim 13 , wherein the at least one processor adjusts the geographic range of the HD map data based on the traveling situation information.
