Abstract

An embodiment vehicle power management apparatus includes a memory configured to store a threshold state of charge (SOC) and a processing device functionally connected with the memory, wherein the processing device is configured to set a power management mode to a camping mode, identify a battery SOC, identify whether the battery SOC is greater than or equal to the threshold SOC, and enter the camping mode to allow an operation of a first vehicle function and limit an operation of a second vehicle function in response to the battery SOC being greater than or equal to the threshold SOC.

First claim

What is claimed is:

1. A vehicle power management apparatus comprising:
a memory storing a threshold state of charge (SOC); and
a processing device functionally connected to the memory,
wherein the processing device is configured to:
set a power management mode in the vehicle power management apparatus to a camping mode, wherein the camping mode is a state of the power management mode where a vehicle is used for camping,
identify a battery SOC of the vehicle in response to an ignition of the vehicle being turned off in a state where the camping mode is set,
identify whether the battery SOC is greater than or equal to the threshold SOC, and
enter the camping mode to allow an operation of a first vehicle function and limit an operation of a second vehicle function in response to the battery SOC being greater than or equal to the threshold SOC,
wherein the processing device is configured to automatically release the camping mode in response to the ignition being turned on from being turned off in a state in which the processing device identifies the battery SOC.

2. The vehicle power management apparatus of claim 1 , wherein the processing device is configured to set the power management mode to the camping mode in response to the vehicle entering a camping place to be parked as identified based on map data.

3. The vehicle power management apparatus of claim 1 , wherein the processing device is configured to set the power management mode to the camping mode based on a user input received from a user interface in a user setting menu.

4. The vehicle power management apparatus of claim 1 , wherein the first vehicle function includes a room lamp on and off function or a door unlock function.

5. The vehicle power management apparatus of claim 1 , wherein the processing device is configured to monitor the battery SOC after entering the camping mode and output a warning in response to the battery SOC decreasing to a predetermined reference SOC or less.

6. The vehicle power management apparatus of claim 1 , wherein the processing device is configured to switch the power management mode to a power-saving mode in response to the battery SOC being less than the threshold SOC.

7. The vehicle power management apparatus of claim 6 , wherein the processing device is configured to enter the power-saving mode to limit an operation of the first vehicle function and the second vehicle function sw.

8. The vehicle power management apparatus of claim 6 , wherein the processing device is configured to release the power-saving mode in response to receiving a reset command from a reset input device.

9. The vehicle power management apparatus of claim 1 , wherein the second vehicle function comprises lighting of a warning light of a cluster, a seat function, an automatic opening and closing function of a power tailgate, an automatic opening and closing function of a power sliding door, an automatic on and off function of a room lamp as a vehicle door is opened and closed, or an automatic on and off function of a tailgate luggage lamp as a tailgate is opened and closed.

10. A vehicle power management method comprising:
setting a power management mode in a power management apparatus to a camping mode, wherein the camping mode is a state of the power management mode where a vehicle is used for camping;
identifying, by a processing device, a battery state of charge (SOC) of the vehicle in response to an ignition of the vehicle being turned off in a state where the camping mode is set;
identifying whether the battery SOC is greater than or equal to a predetermined threshold SOC;
entering the camping mode to allow an operation of a first vehicle function and limit an operation of a second vehicle function in response to identifying that the battery SOC is greater than or equal to the predetermined threshold SOC; and
automatically releasing the camping mode in response to the ignition being turned on from being turned off in a state where the processing device identifies the battery SOC.

11. The vehicle power management method of claim 10 , wherein setting the power management mode to the camping mode comprises setting the power management mode to the camping mode in response to the vehicle entering a camping place to be parked as identified based on map data.

12. The vehicle power management method of claim 10 , wherein setting the power management mode to the camping mode comprises setting the power management mode to the camping mode based on a user input received from a user interface in a user setting menu.

13. The vehicle power management method of claim 10 , wherein the first vehicle function includes a room lamp on and off function or a door unlock function.

14. The vehicle power management method of claim 10 , further comprising:
monitoring the battery SOC after entering the camping mode; and
outputting a warning in response to the battery SOC decreasing to a predetermined reference SOC or less.

15. The vehicle power management method of claim 10 , further comprising switching the power management mode to a power-saving mode in response to identifying that the battery SOC is less than the predetermined threshold SOC.

16. The vehicle power management method of claim 15 , wherein switching the power management mode to the power-saving mode comprises entering the power-saving mode to limit an operation of the first vehicle function and the second vehicle function.

17. The vehicle power management method of claim 15 , further comprising releasing the power-saving mode in response to receiving a reset command from a reset input device.

18. The vehicle power management method of claim 10 , wherein the second vehicle function comprises lighting of a warning light of a cluster, a seat function, an automatic opening and closing function of a power tailgate, an automatic opening and closing function of a power sliding door, an automatic on and off function of a room lamp as a vehicle door is opened and closed, or an automatic on and off function of a tailgate luggage lamp as a tailgate is opened and closed.
