Abstract

An apparatus for updating a vehicle and a method thereof may calculate an update time for each update target of an over-the-air (OTA) update for the vehicle in which a battery is charged based on a charging schedule. The apparatus and the method may also perform the OTA update of the vehicle while the battery of the vehicle is being charged, in consideration of the update time for each update target and the charging schedule. By performing the update in conjunction with the charging schedule, it is possible to maintain a stable battery state.

First claim

What is claimed is:

1. An apparatus for updating a vehicle, the apparatus comprising:
a processor configured to
calculate an update time for each update target of an over-the-air (OTA) update for the vehicle in which a battery is charged based on a charging schedule, and configured to perform the OTA update of the vehicle while the battery of the vehicle is being charged, in consideration of the update time for each update target and the charging schedule,
classify an update area for each update target into a first update area where a full update is needed and a second update area where a partial update is possible,
calculate an update time for the first update area and an update time for the second update area, and
perform the partial update of the second update area while the battery is being charged, when the update time of the second update area exceeds a time obtained by subtracting the update time of the first update area from a time during which charging is in progress determined through the charging schedule, after performing the OTA update of the first update area.

2. The apparatus of claim 1 , wherein the processor configures a lookup table associated with the OTA update for each update target and calculates the update time for each update target through the lookup table.

3. The apparatus of claim 1 , wherein the processor performs all of the OTA update for each update target, when the update time for each update target does not exceed the time during which the charging is in progress determined through the charging schedule.

4. The apparatus of claim 1 , wherein the processor performs the OTA update of the first update area prior to the OTA update of the second update area while the battery is being charged.

5. The apparatus of claim 1 , wherein the processor performs the OTA update of the first update area while the battery is being charged, when the OTA update of the first update area is possible within the time during which the charging is in progress determined through the charging schedule.

6. The apparatus of claim 1 , wherein the processor performs the OTA update depending on whether a power supply state, which is determined in consideration of a state of the battery, is an updateable power supply state.

7. The apparatus of claim 1 , wherein the processor resets the charging schedule by applying a consumption amount of the battery consumed in the OTA update.

8. The apparatus of claim 1 , wherein the processor performs the OTA update of the vehicle in consideration of the update time for each update target and the charging schedule when the battery of the vehicle is in slow charging.

9. A method of updating a vehicle, the method comprising:
calculating an update time for each update target of an over-the-air (OTA) update for the vehicle in which a battery is charged based on a charging schedule;
performing the OTA update of the vehicle while the battery of the vehicle is being charged, in consideration of the update time for each update target and the charging schedule;
classifying an update area for each update target into a first update area where a full update is needed and a second update area where a partial update is possible;
calculating an update time for the first update area and an update time for the second update area; and
performing the partial update of the second update area while the battery is being charged, when the update time of the second update area exceeds a time obtained by subtracting the update time of the first update area from a time during which charging is in progress determined through the charging schedule, after performing the OTA update of the first update area.

10. The method of claim 9 , further comprising:
configuring a lookup table associated with the OTA update for each update target,
wherein the calculating of the update time for each update target includes calculating the update time for each update target through the lookup table.

11. The method of claim 9 , wherein the performing of the OTA update of the vehicle, in consideration of the update time for each update target and the charging schedule, includes
performing all of the OTA update for each update target, when the update time for each update target does not exceed the time during which the charging is in progress determined through the charging schedule.

12. The method of claim 9 , wherein the performing of the OTA update of the vehicle, in consideration of the update time for each update target and the charging schedule, further includes
performing the OTA update of the first update area prior to the OTA update of the second update area while the battery is being charged.

13. The method of claim 9 , wherein the performing of the OTA update of the vehicle, in consideration of the update time for each update target and the charging schedule, includes
performing the OTA update of the first update area while the battery is being charged, when the OTA update of the first update area is possible within the time during which the charging is in progress determined through the charging schedule.

14. The method of claim 9 , wherein the performing of the OTA update of the vehicle, in consideration of the update time for each update target and the charging schedule, further includes
performing the OTA update depending on whether a power supply state, which is determined in consideration of a state of the battery, is an updateable power supply state.

15. The method of claim 9 , further comprising:
resetting the charging schedule by applying a consumption amount of the battery consumed in the OTA update.

16. The method of claim 9 , wherein the performing of the OTA update of the vehicle, in consideration of the update time for each update target and the charging schedule, includes
performing the OTA update of the vehicle in consideration of the update time for each update target and the charging schedule when the battery of the vehicle is in slow charging.
