## Abstract

The present disclosure relates to a vehicular electronic device including a power supply configured to supply power, an interface configured to receive high-definition (HD) map data on a specific area from a server through a communication device, and at least one processor configured to continuously generate electronic horizon data on a specific area based on the HD map data in the state of receiving the power, wherein the processor generates first electronic horizon data on a first section, and, upon determining that a vehicle is traveling the first section again after having travelled the first section based on the first electronic horizon data, does not generate electronic horizon data on the first section.

## Claims

### Claim 1

A vehicular electronic device comprising:
a power supply configured to supply power;
a memory configured to store data;
an interface configured to receive, from a server through a communication device, map data regarding an area within a predetermined range from a location of a vehicle; and
at least one processor configured to:
generate electronic horizon data on the area based on the map data and the location of the vehicle in a state of receiving the power from the power supply, and
provide the electronic horizon data to a driving system of the vehicle to thereby cause the driving system to operate the vehicle based on the electronic horizon data, wherein the at least one processor is further configured to:
generate first electronic horizon data regarding a first section, the first section including an area from a first point to a second point in the map data,
determine whether the vehicle travels the first section based on at least one of location data of the vehicle or traveling record data of the vehicle,
based on a determination that a number of times the vehicle has travelled the first section is greater than or equal to a reference number, store the first electronic horizon data in the memory,
based on a determination that the vehicle is traveling the first section again, retrieve the first electronic horizon data from the memory without generating electronic horizon data regarding the first section, and
based on a determination that the map data on the first section has changed, generate second electronic horizon data based on the changed map data.

### Claim 2 (depends on 1)

The vehicular electronic device of claim 1, wherein the first electronic horizon data comprises first horizon path data, the first horizon path data being defined as a trajectory to be taken by the vehicle within the first section.

### Claim 3 (depends on 1)

The vehicular electronic device of claim 1, wherein the processor is configured to acquire first dynamic data regarding the first section and apply the first dynamic data to the first electronic horizon data.

### Claim 4 (depends on 3)

The vehicular electronic device of claim 3, wherein the first dynamic data includes at least one of construction information, variable-speed road information, road condition information, traffic information, or moving object information regarding the first section.

### Claim 5 (depends on 4)

The vehicular electronic device of claim 4, wherein the at least one processor is configured to generate the first electronic horizon data based on the map data, the first dynamic data, and the location of the vehicle.

### Claim 6

A system comprising:
a server configured to provide map data; and
a vehicle comprising an electronic device configured to receive the map data,
wherein the electronic device comprises:
a power supply configured to supply power;
a memory configured to store data;
an interface configured to receive, from the server through a communication device, the map data on an area within a predetermined range from a location of the vehicle; and
at least one processor configured to: generate electronic horizon data on the area based on the map data and the location of the vehicle in a state of receiving the power from the power supply, and
provide the electronic horizon data to a driving system of the vehicle to perform a driving operation,
wherein the at least one processor is further configured to:
generate first electronic horizon data regarding a first section, the first section including an area from a first point to a second point in the map data,
determine whether the vehicle travels the first section based on at least one of location data of the vehicle or traveling record data of the vehicle,
based on a determination that a number of times the vehicle has travelled the first section is greater than or equal to a reference number, store the first electronic horizon data in the memory,
based on a determination that the vehicle is traveling the first section again, retrieve the first electronic horizon data from the memory without generating electronic horizon data regarding the first section, and
based on a determination that the map data on the first section has changed, generate second electronic horizon data based on the changed map data.

### Claim 7 (depends on 6)

The system of claim 6, wherein the first electronic horizon data comprises first horizon path data, the first horizon path data being defined as a trajectory to be taken by the vehicle within the first section.

### Claim 8 (depends on 6)

The system of claim 6, wherein the processor is configured to acquire first dynamic data regarding the first section and apply the first dynamic data to the first electronic horizon data.

### Claim 9 (depends on 8)

The system of claim 8, wherein the first dynamic data includes at least one of construction information, variable-speed road information, road condition information, traffic information, or moving object information regarding the first section.
