Abstract

Provided are a smartkey operating system equipped with a wireless charging function and an operating method thereof, which controls performing of a wireless charging function equipped in a smartkey system, thereby preventing an overlap of frequencies even when there is an overlap section between a wireless charging operating frequency and a low frequency of the smartkey system. The smartkey operating system includes a switching unit configured to cut off or supply the wireless charging power, and a control unit configured to determine whether to cut off the wireless charging power to control the switching unit according to a current mode. When the current mode is a fob search mode, the control unit cuts off the wireless charging power by using the switching unit.

Claims

1. A smartkey charging apparatus equipped with a wireless charging function, which supplies wireless charging power, the smartkey charging apparatus comprising:

a switching unit configured to cut off or supply the wireless charging power; and

a control unit configured to determine whether to cut off the wireless charging power according to a current mode, wherein in response to the current mode being a fob search mode, the control unit cuts off the wireless charging power for at least the duration of the fob search mode by controlling the switching unit.

2. The smartkey charging apparatus of claim 1, wherein,

the switching unit comprises a high side switch, and

the switching unit cuts off the wireless charging power by using the high side switch.

3. The smartkey charging apparatus of claim 1, wherein in response to the current mode being a sleep mode, the control unit cuts off the wireless charging power by using the switching unit.

4. The smartkey charging apparatus of claim 3, further comprising a display unit configured to display a sleep-mode state according to a control command of the control unit in response to the current mode being the sleep mode.

5. The smartkey charging apparatus of claim 4, wherein the display unit displays a fob search-mode state according to the control command of the control unit in response to the current mode being the fob search mode.

6. The smartkey charging apparatus of claim 4, wherein the display unit displays a wireless charging power supply state according to the control command of the control unit in response to the current mode being a default mode.

7. A smartkey charging apparatus equipped with a wireless charging function, the smartkey charging apparatus comprising:

a coil configured to be used for wireless charging and data communication;

a switching unit configured to include a high side switch, which cuts off or supplies wireless charging power, and an analog switch that switches the coil according to an operation; and

a control unit configured to control the switching unit by determining whether to cut off the wireless charging power and a use of the coil for at least the duration of a current mode in response to the current mode being a sleep mode or a fob search mode.

8. The smartkey charging apparatus of claim 7, wherein in response to the current mode being the sleep mode, the control unit controls the high side switch to cut off the wireless charging power.

9. The smartkey operating charging apparatus of claim 7, wherein in response to the current mode being the fob search mode, the control unit controls the high side switch to cut off the wireless charging power.

10. The smartkey charging apparatus of claim 7, wherein in response to the current mode being a default mode, the control unit controls the high side switch to supply the wireless charging power.

11. The smartkey charging apparatus of claim 7, wherein in response to an emergency start button being in a turn-on state, the control unit controls the analog switch to be used for wireless response.

12. The smartkey charging apparatus of claim 7, wherein in response to a fob diagnosis learning request being acquired, the control unit controls the analog switch to be used for wireless response.

13. A method of operating a smartkey charging apparatus equipped with a wireless charging function, which supplies wireless charging power and in which a switch is ordinarily used for wireless charging, the method comprising:

cutting off the wireless charging power, for at least the duration of a sleep mode or a fob search mode, in response to a current mode being the sleep mode or the fob search mode;

supplying the wireless charging power in response to the sleep mode or the fob search mode ending; and

switching the switch to be used for data communication in response to a fob battery being discharged, and an emergency start button is in a turn-on state or a fob diagnosis learning request is acquired.

14. The method of claim 13, wherein the switching of the switch comprises switching an analog switch.

15. The method of claim 13, further comprising displaying a sleep-mode state in response to a current mode being the sleep mode, or displaying a fob search-mode state in response to the current mode being the fob search mode.

16. The method of claim 13, further comprising switching the switch to be used for wireless charging in response to the emergency start button being in a turn-off state or the fob diagnosis learning request is not acquired.

17. The method of claim 16, wherein the switching of the switch comprises controlling an analog switch to switch the switch.
